Abstract
A collision between a vehicle and an obstacle is estimated, and based on the estimation result, vehicle deceleration control is performed by a brake actuator to reduce the collision and vehicle wheel load is controlled by a suspension actuator.
Claims13
A safety control apparatus for avoiding collision used in a vehicle comprising:
- a headway distance/relative speed detection unit measuring a distance and relative speed between the vehicle and an obstacle;
- a collision determination unit estimating and determining a collision with the obstacle based on the distance and relative speed measured by the headway distance/relative speed detection unit;
- a brake actuator controlling a brake to perform deceleration;
- and
- a suspension actuator controlling a suspension to vary one of or both a vehicle height and a damping coefficient of a shock absorber,
- wherein the collision estimation and determination is performed by the collision determination unit, whereby the vehicle deceleration control by applying the brake is performed by the brake actuator to reduce impact upon collision and along with the deceleration control, vehicle wheel load is controlled by the suspension actuator.
