Driver support systems without active intervention can be viewed as a pre-stage to vehicle guidance. They only warn the driver or suggest a driving manoeuvre. ○ Collision-mitigation systems – in addition to sending out a warning to the driver (either through audio, visual or vibrating the steering wheel), these systems aim to assess the danger ahead and activate various active safety features, such as pre-tensioning the seatbelts. ○ Collision-avoidance systems – using these systems means that some degree of control is taken over from the driver if he/she doesn’t react in time to avoid a crash.
