A reinforcing member for vehicles comprises a pair of fixed parts fastened on spaced-apart portions of a vehicle body, and a bar body for connecting the respective fixed parts. A rotation allowing mechanism is provided on at least one of the fixed parts in order to allow the bar body to rotate with respect to the vehicle body. Therefore, the respective two portions of the vehicle body, on which the fixed parts are fastened respectively, are allowed to have angle variations to each other without changing the space between the two portions of the vehicle body. Consequently, the rigidity of the entire vehicle body can be improved without the degradation in the drivability and the ride comfortableness of the vehicle.

摘要:
In a configuration where a main control unit and various peripheral modules are bus-connected on a communication line, the communication line includes a control line in addition to signal lines serving as a differential pair. The control line is, for example, a bus of the logical AND. When the main control unit drives the control line to a ‘L’ level for a certain period of time or more, the peripheral modules detect that and carry out a hardware reset for itself. When the main control unit issues a command to output a value of a particular bit of own identification number to the peripheral modules via the signal lines, the peripheral modules output the result to the control line, and the control line performs an AND operation. By utilizing the AND operation result, automatic address allocation to the peripheral modules is carried out.
