Occupant restraint system
First Claim
1. An occupant restraint system comprising:
- an occupant restrainer;
a collision predictor which judges whether or not a vehicle is likely to collide with an object, and outputs a pre-crash signal indicating a prediction of a collision of the vehicle with the object when the vehicle is likely to collide with the object;
an acceleration detector which detects a degree of acceleration of the vehicle and starts outputting an acceleration signal indicating the detected degree of acceleration in response to the outputting of the pre-crash signal from the collision predictor; and
an occupant restraint controller which processes the acceleration signal outputted from the acceleration detector to obtain a processing result, and actuates the occupant restrainer when the processing result indicates a collision of the vehicle with the object.

Abstract
An occupant restraint system of a vehicle has an airbag, a pre-crash sensor which calculates a probability of a collision of a vehicle with an object and outputs a pre-crash signal indicating a prediction of the collision when the probability is higher than a predetermined value, a satellite sensor which detects a degree of acceleration of the vehicle and starts outputting an acceleration signal indicating the detected degree of acceleration in response to the pre-crash signal, and an airbag ECU which processes the acceleration signal to obtain a processing result and deploys the airbag when the processing result indicates a collision of the vehicle with the object. Therefore, because the airbag ECU does not start processing the acceleration signal until the satellite sensor outputs the acceleration signal in response to the pre-crash signal, a load on the airbag ECU can be alleviated.
