ADAS to Autonomous: Front Assist

Volkswagen Front Assist is a system designed to help avoid or mitigate accidents into the rear of preceding traffic.

VW vehicles have a long-range radar at the front of the car that can detect vehicles up to 80m ahead which the car is likely to hit if no action is taken. The information from the front radar can be combined with data from a windscreen-mounted camera to calculate the probability of an impact.Screen Shot 2017-03-07 at 1.21.19 pm

When the system calculates that a collision is likely, it issues an optical and an acoustic warning and pre fills the braking system in preparation for an avoidance maneuver by the driver. If the driver does not react and the criticality increases a further warning is given: a small braking jolt serves as a ‘haptic’ warning, encouraging a driver reaction. At the same time, the brakes are prepared so that if the driver does brake, Front Assist will automatically apply the braking force needed to avoid or mitigate the collision. If there is still no reaction from the driver, the system autonomously applies braking to try to mitigate a collision.

Up to 30km/h Front Assist applies full braking, and can detect moving or stationary objects. Between 30km/h and 80km/h, there is no automatic braking but the system will warn the driver if it detects a stationary object. In moving traffic, between 30km/h and 200km/h, the system applies its full capacity of driver warnings, partial braking and brake assistance.
