Adaptive cruise control with Porsche Active Safe (PAS)

Adaptive cruise control including Porsche Active Safe (PAS).

Also available as an option is the enhanced version of cruise control, which regulates the speed of your vehicle in line with the speed of the vehicle in front. A radar sensor scans the road ahead up to a distance of 200 m.

Imagine you’ve selected a cruising speed but have begun to gain on the vehicle in front because it is driving more slowly – this is detected by the radar sensor. The system now reduces the speed of your vehicle at a maximum rate of 3.5 m/sec² by restricting throttle or by applying the brakes as appropriate to the prevailing situation until your chosen distance from the vehicle in front is maintained.

Your vehicle now follows the vehicle ahead at a reduced speed. If the vehicle ahead slows further, adaptive cruise control will decelerate your vehicle accordingly – even down to a halt. As soon as the road ahead clears, your vehicle will accelerate back up to the cruising speed originally set.

Porsche Active Safe (PAS) issues an audible and a visual warning if the system detects that your vehicle is approaching the vehicle in front too quickly. This is accompanied by a brief jolt of the brakes and, where necessary, the initiation of targeted braking. During this process, any braking by the driver is boosted to achieve the maximum braking force that the system is able to provide.
