Abstract
A vehicle air bag control system includes an impact detector for detecting impact on a vehicle and for outputting an impact detection signal, an air bag deployment determination unit for outputting a deployment command when the impact detection signal is more than a predetermined value, a state estimation unit for estimating whether a vehicle engine is stopped during an idling stop, and a power control unit for driving the impact detector, the air bag deployment determination unit and the state estimation unit when the vehicle engine is stopped during an idling stop as indicated by the state estimation unit.
Claims18
A vehicle air bag control system comprising:
- an impact detector for detecting an impact on a vehicle and for outputting an impact detection signal;
- an air bag deployment determination unit for outputting a deployment command when the impact detection signal is more than a predetermined value;
- a state estimation unit for estimating whether a vehicle engine is stopped during an idling stop;
- and
- a power control unit for driving the impact detector, the air bag deployment determination unit and the state estimation unit when the vehicle engine is stopped during the idling stop as indicated by the state estimation unit.
A vehicle air bag control system comprising:
- an impact detector for detecting an impact on a vehicle and for outputting an impact detection signal;
- and
- a microprocessor configured
- to output an air bag deployment command when the impact detection signal is more than a predetermined value,
- to estimate whether a vehicle engine is stopped during an idling stop, and
- to drive the impact detector and deploy an air bag when the vehicle engine is stopped during the idling stop.
A method of controlling a vehicle air bag comprising:
- detecting an impact on a vehicle and outputting an impact detection signal by using an impact detector;
- and
- providing a microprocessor that is configured to:
- output an air bag deployment command when the impact detection signal is more than a predetermined value;
- estimate whether a vehicle engine is stopped during an idling stop;
- and
- drive an impact detector and deploy the air bag when the vehicle engine is stopped during the idling stop.
