Abstract: When a microcomputer of an electronic control unit determines that an ACC switch undergoes OFF-ON shift, the mobile telephone is controlled to shift the power supply state from the power supply OFF to the power supply ON. If the time passing after the ACC switch undergoes the OFF-ON shift is within a certain period of time, the mobile telephone is controlled to maintain the power supply OFF state. Therefore, even when the ACC switch is turned on and off repeatedly, it is prevented that the power supply of the mobile telephone is turned on and off repeatedly in connection with the repetition of the ON/OFF of the ACC switch.

Abstract: A shock absorber control system comprises a plurality of switches for setting respective desired dampening forces, and controls a dampening force of a vehicle shock absorber linearly in accordance with a manipulation of one of the switches. The control system further comprises a height sensor for detecting a height of the vehicle and detects the dampening force of the shock absorber by the change of the detected height and corrects the dampening force of the shock absorber in accordance with a difference between the desired dampening force corresponding to the manipulated switch and the detected dampening force.
