PROBLEM TO BE SOLVED: To enable preventing that adverse effect is exerted on a portable telephone by repetition of ON/OFF of an ACC switch, even if the ON/OFF is performed repeatedly. SOLUTION: When a microcomputer 15 of electronic control equipment 10 decides that the ACC switch is subjected to OFF-ON transition (S100), the portable telephone is so controlled that transition from power source OFF to power source ON is performed in the state of power source (S120). When the elapsed time from OFF-ON transition of the ACC switch is shorter than a definite time T1, the portable telephone is so controlled that a power source OFF state is held (S130). As a result, repetition of power source ON/OFF of the portable telephone which is to be generated together with repetition of ON/OFF of the ACC switch can be prevented even if ON/OFF of the ACC switch is performed repeatedly. |
