摘要： In a passenger weight measuring apparatus, each of bend parts of front and rear brackets for supporting a seat to a vehicle main body side becomes bent and deformed in response to the load applied by the weight of the passenger sit in the seat. A load sensor on each the bend part detects the load based on the bend deformation and outputs a voltage signal of magnitude responsive to the load to a signal processor. The processor generates a load detection signal clamped in the voltage range corresponding to a preset passenger weight load range from the voltage signal and outputs the load detection signal to an output terminal. When the detected load is a collision load set in a load region out of the load range, the processor outputs an abnormal load detection signal different from the load detection signal to the same output terminal.

摘要： A weight detector for detecting the weight of a passenger seated on a vehicle seat includes a first load sensor and a second load sensor provided on opposite sides of a rear portion of the vehicle seat. Each of the first and second load sensors has a predetermined detection range. The weight detector further includes a third load sensor and a fourth load sensor provided on opposite sides of a front portion of the vehicle seat. Each of the third and fourth load sensors has a predetermined detection range. If a detection value based on a load acquired by one of the first through fourth load sensors exceeds its detection range, the weight detector uses an old value that was determined under proper condition. Otherwise, the weight detector determines the size of the passenger based on the currently detected values.

摘要： An information request portion receives an information request signal transmitted to an information response portion at its own receiving port. The information request portion comprises at least either of a power supply system anomaly determination portion or a ground anomaly determination portion. The power supply system anomaly determination portion determines a short-circuit between a signal line and a power supply system in a case where the information request signal received at the receiving port is always fixed to a H (high) level. The ground anomaly determination portion determines a short-circuit between a signal line and a ground in a case where the information request signal received at the receiving port is always fixed to a L (Low) level. Consequently, the anomaly region of the signal line connecting the information request portion and the information response portion in such a manner that bidirectional digital communications are possible or the cause of the anomaly is specified.
