Test drive MERCEDES-BENZ ACTROS: TRUCK WITH REAR EYES
Cameras instead of mirrors and the second level of autonomous control
Mercedes-Benz has officially presented the fifth generation of Actros in Bulgaria, nicknamed “digital tractor” for a reason. On a special media test drive, I was convinced of its much improved maneuverability thanks to cameras that replace mirrors, as well as its almost automated control on intercity roads and highways, which greatly facilitates the driver's work. Truck of the Year 2020 can reduce fuel consumption by up to 3% on highways and up to 5% on intercity routes. This is achieved through technological innovations focused on safety and autonomous driving, as well as digital innovations that optimize handling and fuel consumption.
Visibility
Undoubtedly the most impressive innovation is the rearview mirror replacement cameras. Called MirrorCam, the system reduces drag in aerodynamically optimized vehicles, reducing fuel consumption by about 2% at high speeds. The camera also provides a wider perimeter observation compared to a classic mirror, allowing continuous monitoring of the rear of the trailer, even in the sharpest corners. Simply put, if you break the track at a bend, you will not only see the logo of the trailer you are pulling, but also what is happening behind it and that you can move.
In addition, when reversing, a digital marker showing the end of the trailer can be displayed on a mirror change screen located inside the cab. Thus, there is no danger of colliding with the ramp when loading or getting trapped, for example when overtaking. We tested the system in a specially prepared landfill, and even colleagues without a category and getting into a truck for the first time could easily park it. In real traffic, the advantage is even greater, especially on the roundabouts. Cameras significantly increase safety while in a parking lot. When the driver pulls down the curtains to sleep, ordinary mirrors remain outside and he cannot see what is happening around the truck. MirrorCam, however, have motion sensors, and if, for example, someone tries to steal cargo, drain fuel or push refugees into the body, the screens inside "light up" and show the driver in real time what is happening outside.
Similar to the concept of Mercedes-Benz cars, the conventional dashboard is replaced by two displays that show information about the ride and the technical condition of the car. The MBUX infotainment system (developed in Bulgaria by Visteon) for trucks is much more complex in terms of architecture and comprehensive in terms of vehicle handling. In addition to the display in front of the steering wheel, a 10-inch center display is standard, which replaces the instrument cluster and integrates radio controls, interior and exterior lighting, navigation, all Fleet Board telematics functionality, vehicle settings, air conditioning and heating. Apple car play and Android Auto.
From space
One of the most valuable driver aids is the cruise control and engine and transmission management system, which ensures economy and reduces fuel consumption. It uses not only satellite information about the location of the vehicle, but also accurate digital 3D road maps built into the tractor system. They contain information about speed limits, topography, turns and geometry of intersections and roundabouts. Thus, the system not only calculates the required speed and gear according to the road conditions, but also optimizes the driving style depending on the complexity of the particular road section.
Combined with Active Drive Assist, driver efficiency is greatly improved. With this feature, Mercedes-Benz became the first truck manufacturer to reach the second level of autonomous driving. The system combines comfort and safety functions - a distance control assistant to the front vehicle and a system that monitors the lane and actively adjusts the angle of the tires. Thus, when driving, the car autonomously maintains its position within the lane and autonomous transverse and longitudinal steering is provided. We tested it on the Trakia, it works flawlessly in areas where there are markings. It is important to note that due to legal restrictions, this system works completely autonomously within 1 minute
Active Break Assist also plays a key role in safety. When driving at speeds up to 50 km / h, the truck can perform a full emergency stop upon detecting a moving pedestrian. When driving outside the village at a speed of more than 50 km / h, the system can completely stop in an emergency (detection of a stopped or moving vehicle in front), thereby preventing a collision.
Big Brother
The new Actros is also equipped with the Mercedes-Benz Uptime system for proactive monitoring of the technical condition of the car and the presence of active errors recorded in the on-board electronics of the car. The system provides preliminary information about the technical problem by transmitting it to the data center, where it is analyzed by the maintenance team. The goal is to prevent a forced stop on the road due to an accident. Fleet Board telemetry system for fleet monitoring and management is now available as standard. This helps trucking company owners optimize costs, increase vehicle capacity, and even anticipate upcoming maintenance such as pad changes or oil changes. Information in it comes from each truck on the road in real time, both to a personal computer, and smart devices of fleet managers. It monitors more than 1000 vehicle parameters and is an indispensable assistant when performing logistic tasks.
