The ECU 2 stops the operation of the adaptive cruise control and informs the ECU 1. of non-operation state of the adaptive cruise control during the operation of the adaptive cruise control, when the preceding vehicle is lost, for example, because of an acceleration of the preceding vehicle (step S155). The ECU 1 resumes the operation of the cruise control (step S115: NO->step S120). The adaptive cruise control is resumed when the subject vehicle catches up the preceding vehicle (step S155: YES->step S160).
