The driver is still fully responsible for the driving task and must always pay attention to traffic, encompass the steering wheel, and be ready for braking. However, advanced assistance systems are at driver´s disposal. When driving assisted, the assistance systems support either steering and braking or accelerating, either laterally or longitudinally, but not simultaneously. For example, Level 1 includes either a lane keeping assist (LKA) or an adaptive cruise control (ACC) with which the vehicle regulates the speed and its distance from the vehicle in front. The driver can override them at any time or even switch them off (if and on/off control is available). These advanced driver assistance systems (ADAS) are already available in almost all vehicle classes. ZF also offers a multitude of them.
