Abstract
A shock detection system with a vehicle at rest includes a parking mechanism for locking rotation of a drive shaft which rotates a wheel of the vehicle, a revolution sensor for detecting a revolution speed of the drive shaft, and a shock detector for detecting a shock to the vehicle based on a magnitude and a frequency of variation in detection values of the revolution speed of the drive shaft detected by the revolution sensor in a state where the rotation of the drive shaft is locked by the parking mechanism.

A shock detection system with a vehicle at rest, comprising:
- a parking mechanism for locking rotation of a drive shaft which rotates a wheel of the vehicle;
- a revolution sensor for detecting a revolution speed of the drive shaft;
- and
- a shock detector for detecting a shock to the vehicle based on a magnitude and a frequency of variation in detection values of the revolution speed of the drive shaft detected by the revolution sensor in a state where the rotation of the drive shaft is locked by the parking mechanism.
A shock detection method with a vehicle at rest, comprising the steps of:
- (a) detecting a revolution speed of the drive shaft by a revolution sensor in a state where a parking mechanism for locking rotation of a drive shaft which rotates a wheel of the vehicle is used to lock the rotation of the drive shaft;
- and
- (b) detecting a shock to the vehicle based on a magnitude and a frequency of variation in detection values of the revolution speed of the drive shaft detected.
