All systems which actively intervene to help defuse critical driving situations and prevent accidents from happening come under the heading of active safety.
Driver assistance systems such as ESP, brake assist, Front Assist and Side Assist are of central importance in this respect.
The main aspects of active safety are:
- Directional stability: this is the result of the chassis set-up with regard to drive concept, suspension and cornering stability. Steering precision, braking power and braking stability also have a role to play.
- Physiological safety: this describes the strain placed on the occupants by vehicle vibrations, noise from the chassis and engine as well as climatic influences.
- Perceptual safety: this is improved by a well-designed vehicle lighting layout and by good visibility (all-round view, clear view to the rear with the blind spot kept as small as possible).
- Operational safety: this is achieved thanks to the logical arrangement of all control stalks and switches for e.g. the lights, windscreen wipers, air conditioning and infotainment systems. All elements must be placed within easy reach of the driver in the best position possible.
The combination of active and passive safety features helps to ensure optimum protection for all occupants of the vehicle.
