Traffic jam assistant.
Traffic jam assistant eases the burden on the driver on motorways and in other monotonous traffic situations. At speeds of up to 60 km/h, the system lets the car simply "glide along" with the other cars in dense traffic situations, making traffic jams less stressful.
It automatically maintains the desired distance from the vehicle ahead and regulates the car's speed down to standstill, as well as providing active steering support. The vehicle is therefore able to help the driver stay in the correct lane, as long as the driver keeps at least one hand on the wheel. Having been at a complete standstill for up to 30 seconds (instead of the three seconds which was the case up until now), the car automatically starts moving again. This represents another milestone on the path to achieving highly automated driving.
