Security Systems: Front Assist

System "Front Assist" Volkswagen Its main function is to monitor the distance to the vehicles in front, and to recognize those situations in which this distance is too small. it safety and prevention system, which warns the driver and brakes automatically in the event of a collision threat. Its advantage is that such a system can help reduce the severity of an accident or even avoid it.

The city's emergency braking function and pedestrian detection system are also part of Front Assist. So, it warns if you are driving too close to an obstacle and, if necessary, slows down the car automatically when the car is moving at high speed.

Let's take a closer look at how this system works and its main functions:

What specific features does Front Assist include?

SECURITY DISTANCE SENSOR

A distance sensor visually alerts the driver when he is driving less than 0,9 seconds from the front of the vehicle. The distance to the vehicle in front must be sufficient to stop the car without exposing itself to danger of a collision if it brakes abruptly.

The functioning of the system is divided into the following phases:

• Observation: The distance sensor uses a radar sensor at the front of the vehicle to measure the distance to the vehicle in front. The sensor software contains tables of values ​​that determine the critical distance as a function of speed.
• A warning: If the system detects that the car is approaching too close to the car that is driving ahead, and this poses a safety hazard, it warns the driver with an appropriate sign.

EMERGENCY BRAKE FUNCTION IN THE CITY

An additional Front Assist function that controls the area in front of the car when you are moving slowly.

Work:

• Control: The emergency braking function in the city continuously monitors the distance to the vehicle in front.
• A warning: First, it warns the driver with optical and acoustic signals, followed by a deceleration.
• And auto braking: If the driver brakes at low intensity in critical situations, the system generates the braking pressure necessary to prevent a collision. If the driver does not brake at all, Front Assist brakes the car automatically.

PEDESTRIAN DETECTION SYSTEM

This function combines information from the radar sensor and front camera signals to detect pedestrians near the road and on the roadway. When a pedestrian is detected, the system issues a warning, optical and acoustic, and causes braking if necessary.

Job:

• Monitoring: The system is able to detect the possibility of a collision with a pedestrian.
• A warning: A warning is issued to the front camera, and the driver receives warnings, in optical and acoustic form.
• And auto braking: If the driver brakes at low intensity, the system generates the brake pressure necessary to prevent a collision. Otherwise, if the driver does not brake at all, the car brakes automatically.

Without a doubt, Front Assist is another step in the field of safety and a necessary feature for any modern car.
