PROBLEM TO BE SOLVED: To provide a program for performing initialization of ID setting or the like to a plurality of sensors, and flexibly coping with specification change such as a change in the number of buses to which the respective sensors are connected even when there is the specification change.SOLUTION: A plurality of sensors are mounted on a front bumper and a rear bumper of a vehicle, and the sensors are connected with an ECU by one bus. Software (a program) 5 for performing initialization processing of ID setting or the like to the respective sensors in system startup is installed in a ROM of the ECU. The software 5 has a software structure 50 in which unit programs 5a showing initialization processing to one sensor group are arranged in a matrix. A left arranged part 511 of the software structure 50 is selected as programs to be used. The ECU supplies power to a sensor group of the front bumper and a sensor group of the rear bumper in this order and executes the initialization processing by sequentially executing two unit programs 5a1, 5a2 of the arranged part 511. |
