1. A collision object discrimination apparatus for vehicles, comprising:
- a collision load detection sensor fitted to a vehicle body for detecting a collision load applied from a collision object in a longitudinal direction of the vehicle body; and
a collision object discrimination means for discriminating kinds of the collision object based on an output of the collision load detection sensor, characterized by a collision width detection sensor fitted to the vehicle body for detecting a collision width of the collision object in a lateral direction of the vehicle body, wherein the collision object discrimination means attains a collision object discrimination based on an output of the collision width detection sensor in addition to the output of the collision load sensor.

Abstract
A collision object discrimination apparatus for vehicles includes two collision detection sensors for discriminating kinds of a collision object based on two sensor outputs. The collision object is determined based on a collision width (W) detected by a collision width detection sensor fitted to a vehicle body. Alternatively, the collision object is determined based on a difference between operation characteristics of the two sensors. Further alternatively, the two sensors are integrated into a single unit including a plurality of censor cells.
