Test Drive Bosch Shows Innovation at IAA 2016
Trucks of the future are connected, automated and electrified
Bosch turns the truck into a technology showcase. At the 66th International Truck Show in Hannover, the technology and service provider presents its ideas and solutions for the connected, automated and electrified trucks of the future.
Everything can be seen on digital side mirrors and modern displays.
New displays and user interface: Connectivity and infotainment are evolving. Bosch is installing large displays and touch screens in trucks to make these features easier to use. Freely programmable displays always show important information. For example, in hazardous situations, the display prioritizes warnings and visually focuses on them. The buttons on the Bosch neoSense touchscreen feel real, so the driver can press them without looking. Easy operation, intuitive menu navigation and fewer distractions are the benefits of the various types of smartphone integration offered by Bosch. Along with Apple CarPlay, Bosch's mySPIN is the only alternative solution for connecting Android and iOS devices to the infotainment system. Bosch is also developing GPS devices that will make maps easily accessible. They include XNUMXD elements such as feature buildings at an additional map level to help users navigate their environment. Also, real-time information about the weather and fuel prices will be displayed.
Digital Exterior Mirror: Large mirrors on the left and right sides of the truck provide a rear view of the driver. While these mirrors are vital for safety, they affect the vehicle's aerodynamics and limit forward visibility. At the IAA, Bosch is presenting a camera-based solution that completely replaces two side mirrors. It is called the Mirror Cam System - "mirror-camera system" and significantly reduces wind resistance, which means it reduces fuel consumption by 1-2%. Video sensors can be integrated into the driver's cab, where monitors are located on which the video image is launched. Digital technologies create a screen for a specific situation. When the truck moves along the highway, the driver sees the car far behind, and in the city the viewing angle is as wide as possible for maximum safety. Increased contrast improves visibility during night courses.
More safety and efficiency on the road with connectivity solutions from Bosch
Connection Control Module: Bosch's Connection Control Module - The Connection Control Unit (CCU) is the central communication unit in commercial vehicles. The CCU communicates wirelessly with its own SIM card and can optionally determine the location of the vehicle using GPS. It is available both in the original configuration and as a module for additional installation. It can be connected to the vehicle's on-board network via the on-board diagnostics (OBD) interface. The CCU sends truck operating data to a cloud server, opening the door to a wide range of potential services. For many years, Bosch has been manufacturing trailer control units. It registers the position of the trailer and the temperature of the cooling, can register strong vibrations and immediately send information to the fleet manager.
Connected Horizon: Bosch's electronic horizon has been on the market for several years, but the company is now expanding it with real-time data. In addition to topographic information, the assistant functions will be able to use data from the cloud in real time. Thus, the engine and gearbox controls will take into account road sections being repaired, traffic jams and even icy roads. Automatic speed control will also reduce fuel consumption and improve vehicle efficiency.
Secure Truck Parking: The smartphone app makes it easy to book parking spaces in the recreation areas, as well as pay online without cash. To do this, Bosch connects the parking infrastructure to the information and communication systems used by dispatchers and truck drivers. Bosch provides real-time parking data from its own cloud. Parking areas are guarded by intelligent video equipment, and access control is provided by identification on license plates.
Entertainment for coaches: Bosch's powerful infotainment systems offer bus drivers a rich interface for downloading various types of multimedia content to the system and playing it on high-resolution monitors and high-definition audio systems also manufactured by Bosch. The Coach Media Router offers passengers the entertainment of their choice with Wi-Fi and streaming of movies, TV shows, music and magazines.
Eyes and ears for assisted and automated driving
MPC - Multifunctional camera: The MPC 2.5 is a multifunctional camera designed especially for heavy trucks. The integrated image processing system identifies, classifies and locates objects in the truck's environment with a high degree of accuracy and reliability. In addition to the emergency braking system, which has been mandatory for all trucks in the EU with a total weight of more than 2015 tons since autumn 8, the camera also opens up the possibility for a number of auxiliary functions. One of them is intelligent headlight control, which automatically turns on the light when driving at night or when entering a tunnel. The camera also helps recognize traffic signs by showing them on the in-cab display to better inform the driver. In addition, the camera is the basis of a number of assistance systems - for example, the lane departure warning system warns the driver by vibration of the steering wheel that he is about to leave the lane. With intelligent safety mechanisms for lane recognition, the MPC 2.5 is also the basis of a lane keeping system that keeps the car in lane with small steering wheel adjustments.
Front medium range radar sensor: For light commercial vehicles, Bosch offers a front range radar sensor (Front MRR). It detects objects in front of the vehicle and determines their speed and position relative to it. In addition, the sensor transmits FM radar waves in the range of 76 to 77 GHz via transmitting antennas. With the front MRR, Bosch implements driver-assisted ACC functions - adaptive cruise control and emergency braking system.
Rear mid-range radar sensor: A rear-mounted version of the Rear MRR radar sensor allows van drivers to monitor blind spots. The cars are equipped with two sensors hidden at both ends of the rear bumper. The system detects all vehicles in the truck's blind spots and alerts the driver.
Stereo camera: Bosch's compact SVC stereo camera is a mono-sensor solution for many driver assistance systems in light commercial vehicles. It fully captures the 3D environment of the car and the empty spaces in front of it, providing a 50m 1280D panorama. Each of the two highly sensitive image sensors equipped with color recognition technology and CMOS (Optional Metal Oxide Semiconductor - Additional MOSFET Logic) has a resolution of XNUMX x XNUMX megapixels. Numerous safety and comfort features are implemented with this camera, from automatic emergency braking to traffic jam assistants, road repairs, narrow sections, avoidable maneuvering and, of course, ACC. The SVC also supports intelligent headlight control, lane departure warning, lane keeping and side guidance, and traffic sign recognition.
Proximity camera systems: With proximity camera systems, Bosch helps van drivers to easily park and maneuver. A CMOS-based rear-view camera gives them a realistic view of their immediate surroundings when reversing. Four macro cameras form the basis of the Bosch multi-camera system. One camera is installed in the front, another in the back, and the other two are in the side mirrors. Each one has a 192 degree aperture and together covers the entire vehicle environment. Thanks to a special imaging technology, three-dimensional images are displayed on the display. Drivers can select the desired perspective to see even the slightest obstacle in the parking lot.
Ultrasonic sensors: It is often difficult to see everything around the van, but Bosch ultrasonic sensors capture the environment up to 4 meters away. They detect possible obstacles and, during maneuvers, determine the constantly changing distance to them. The information from the sensors is sent to the parking assistant, which helps the driver to park and maneuver safely.
Steering systems for Bosch trucks set the course
Bosch Servotwin improves the efficiency and comfort of heavy trucks. The electro-hydraulic steering system offers speed-dependent support for active reaction control that uses less fuel than pure hydraulic power steering. The servo unit reliably compensates for unevenness in the road and provides the driver with good traction. The electronic interface puts the steering system at the center of auxiliary functions such as lane assist and crosswind compensation. The steering system is used in many truck models, including the Actros self-propelled gun. Mercedes-Benz.
Rear Axle Control: eRAS, an electric rear axle steering system, can steer the drive and rear axles of trucks with three or more axles. This reduces the turning radius and consequently reduces tire wear. ERAS consists of two components - a cylinder with an integrated encoder and a valve system and power supply. It consists of an electrically driven pump and a control module. Based on the steering angle of the front axle transmitted via the CAN bus, the steering system determines the optimal steering angle for the rear axle. After the turn, the system takes over the task of straightening the wheels. eRAS consumes power only when the steering wheel is turned.
Electronic airbag control unit: With the electronic airbag control unit, Bosch improves the protection of the driver and passengers of commercial vehicles. The electronic control unit reads the signals sent by the acceleration sensors to determine the impact force and accurately activate the passive safety systems - seat belt pretensioners and airbags. In addition, the electronic control unit constantly analyzes the movement of the vehicle and recognizes critical situations, such as a rollover of a truck. This information is used to activate the seat belt pretensioners and the side and front airbags to mitigate the effects of the crash on the driver and passengers.
Drive electrification increases torque and reduces fuel consumption
48-Volt Starter Hybrid: Fast Recovery System: With the Bosch 48-Volt Starter Hybrid for Light Commercial Vehicles, you can coast to save fuel, and its higher power means it recovers energy better than conventional voltage applications. As a replacement for a conventional belt-driven alternator, the 48V BRM boost system provides comfortable engine starting. Like a high efficiency generator, BRM converts braking energy into electricity that can be used by other consumers or to boost the engine.
Electric hybrid drive: Bosch has developed a 120 kW parallel hybrid system for trucks. It can help reduce fuel consumption by 6%. The system can also be used on trucks weighing between 26 and 40 tons, as well as off-road vehicles. The main components for long-distance transport are the electric motor and power electronics. The compact electric drive is integrated between the engine and gearbox, so no additional transmission is required. It supports the combustion engine, recovers energy, and provides an inertial and electric drive. The inverter converts DC current from the battery into AC current for the motor and regulates the required torque and engine speed. A start-stop function can also be integrated, further increasing the fuel saving potential.
Variable turbine geometry: As in the passenger car segment, requirements for lower fuel consumption and emissions are becoming more stringent. The exhaust turbine plays a very important role. In addition to reducing friction and improving thermodynamic efficiency by optimizing air components, Bosch Mahle Turbo Systems (BMTS) develops Variable Geometry Turbines (VTG) for commercial vehicle engines. Here, development is focused primarily on achieving a high degree of thermodynamic efficiency through the geometry of the entire range and increasing the durability of the system as a whole.
Bosch is preparing an electric drive for construction sites
Electric drive for off-road engines: the future of cars is not only electricity, the future of off-road applications is also connected to electricity. This will make it easier to comply with emission requirements, and electric machines will significantly reduce noise levels, for example, at construction sites. Bosch offers not only various electric drive components, but also a complete drive system for SUVs. Combined with the power storage module, it is suitable for electrification of various applications in the off-road market, including those outside the purely driving range. It can work with both speed control and torque control. The system can be installed on any vehicle by simply connecting it to another module such as an internal combustion engine or another type of transmission such as an axle or chain. And since the required installation space and interface are similar, a series hydrostatic hybrid can be installed at little extra cost.
State-of-the-art Heat Recovery Testing Procedures: Commercial Vehicles with Heat Recovery (WHR) systems reduce costs for fleet operators and conserve natural resources. The WHR system recovers some of the energy lost in the exhaust system. Today, most of the primary energy for driving trucks is lost as heat. Some of this energy can be recovered by the WHR system, which uses the steam cycle. Thus, the fuel consumption of trucks is reduced by 4%. Bosch relies on a combination of computer simulation and realistic bench testing to develop complex WHR systems. The company uses a hot gas dynamic test bench for the safe, repeatable testing of individual components and complete WHR systems in stationary and dynamic operation. The bench is used to test and evaluate the operating effects of fluids on efficiency, pressure levels, installation space and the safety concept of the entire system. In addition, different system components can be compared to optimize the cost and weight of the system.
Modular Common Rail system – the best solution for every requirement
Versatility: The sophisticated common rail system for trucks can meet all current and future requirements for road traffic and other applications. Although the modular system is designed for engines with 4-8 cylinders, on SUVs it can even be used for engines with up to 12. The Bosch system is suitable for engines from 4 to 17 liters and up to 635 kW in the highway segment and 850 kW off-road. ...
The perfect match: System components and modules are combined in various combinations to suit the specific preferences of the engine manufacturer. Bosch manufactures fuel and oil pumps (CP4, CP4N, CP6N), injectors (CRIN) for various mounting positions, as well as the new generation MD1 fuel manifolds and electronic control units optimized for network systems.
Flexibility and Scalability: Because different pressure levels are available from 1 to 800 bar, manufacturers can meet the requirements of a wide range of segments and markets. Depending on the load, the system can withstand 2 million km on the road or 500 1,6 hours off the track. Since the flow rate of the injectors is very high, the combustion strategy can be optimized and ultra-high engine efficiency can be achieved.
Efficiency: The electronically controlled eGP fuel pump adjusts the fuel pre-flow according to demand and thus reduces the required drive power. With up to 8 injections per cycle, the improved injection pattern and optimized injectors further reduce fuel consumption.
Economical: Overall, the modular system reduces fuel consumption by 1% compared to conventional systems. For heavy vehicles this means up to 450 liters of diesel per year. The system is also ready for drive electrification – it can handle the 500 start-stop processes required for hybrid operation.
Other Bosch innovations for combustion trucks
Common Rail Starter System for Emerging Markets: CRSN Baseline systems with system pressures up to 2000 bar for medium and heavy trucks as well as off-road vehicles are ideally suited to the requirements of emerging markets. They are equipped with a wide range of Baseline oil pumps and nozzles. Thanks to a high degree of integration, calibration and certification, new car models can be quickly equipped with these systems.
Natural Gas Power Plants: Gasoline powered trucks are a quiet, economical and environmentally friendly alternative to diesel. Bosch original equipment quality technologies reduce CO2 emissions by up to 20%. Bosch is systematically improving the CNG drive. The portfolio includes components for engine management, fuel injection, ignition, air management, exhaust aftertreatment and turbocharging.
Exhaust Gas Treatment: The stringent legal restrictions will only be respected by an active after treatment system such as an SCR catalyst for the reduction of nitrogen oxide. The Denoxtronic metering system injects a 32,5% urea aqueous solution into the exhaust stream ahead of the SCR catalytic converter. There, ammonia decomposes nitrogen oxides into water and nitrogen. By processing engine operating data and all sensor readings, the system can fine-tune the amount of reductant to match engine operating conditions and catalyst performance to maximize NOx conversion.
