Fahrzeugsicherheitssystem

摘要

A vehicle safety system (10) includes a first vehicle occupant safety device (50) including a first pyrotechnic device (60) that is electrically energizable in response to a first actuation signal (76). The system also includes a second vehicle occupant safety device (50) including a second pyrotechnic device that is electrically energizable in response to a second actuation signal (80). The system includes at least one sensor (14-28) for sensing a first occupant or vehicle condition and for providing a first output signal indicative of the sensed first condition. An electronic control unit (ECU) (30) receives the first output signal (14-28) and in response to the first output signal determines whether one or both of the first and second safety devices should be actuated. An radio frequency (RF) transmitter (40) electrically connected with the ECU (30) is selectively actuatable by the ECU to transmit first and second individually coded RF signals (72, 80). The system (10) includes a first RF receiver (64) electrically connected with the first safety device (50) for receiving the first individually coded RF signal (72) and for providing a first actuation signal (74) for energizing the first pyrotechnic device. The system (10) also includes a second RF receiver electrically connected with the second safety device for receiving the second individually coded RF signal (80) and for providing a second actuation signal for energizing the second pyrotechnic device.
