First Claim
Patent Images
1. A method of classifying an obstacle on the basis of pre-crash sensor signals, the method comprising:
- determining a relative velocity between a vehicle and the obstacle from the pre-crash sensor signals;
determining an obstacle velocity from the relative velocity and a vehicle velocity;
determining an acceleration and an acceleration change from the obstacle velocity; and
classifying the obstacle on the basis of the acceleration, the acceleration change and the obstacle velocity.

Abstract
A method of classifying an obstacle on the basis of pre-crash sensor signals is described, acceleration and acceleration change being determined from the obstacle velocity, and the obstacle is classified on the basis of these parameters. The deployment algorithm is tightened as a function of this classification; if appropriate, restraining means are deployed at an early stage and an automatic braking and/or steering intervention takes place.
