Title:
VEHICLE COLLISION DETECTOR AND VEHICLE COLLISION DETECTION METHOD
Document Type and Number:
Japanese Patent JP2016068901
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve collision detection performance with a simple configuration and with simple processing.SOLUTION: When a motor vehicle on which a passenger rides collides against a vehicle bumper, a deformation amount of the vehicle bumper exhibits characteristics (50) that include a characteristic 52 of a small deformation amount due to the collision against a wheel of the motor vehicle and a characteristic 54 of a relatively large deformation amount with a time difference from the former characteristic. When the deformation amount of the vehicle bumper exceeds a threshold (th3), it is detected that the motor vehicle contacted the vehicle bumper, and a threshold for determining the collision of an object is changed from a threshold (th1) for a pedestrian to a threshold (th2) for detecting the passenger of the motor vehicle for time (T2) for detecting the collision against the passenger of the motor vehicle after passage of waiting time (T1) until the passenger of the motor vehicle secondarily collides. As a result, even the collision against the motor vehicle on which the passenger rides with the small deformation amount can be detected.SELECTED DRAWING: Figure 4
