Patent number: 9308899Abstract: A brake control section can select an automatic mode in which a mechanical brake is automatically transitioned from a released state to a braking state in response to the running condition of a vehicle. A diagnostic section outputs a fail signal when an abnormal condition of the brake control section is detected. A power control section automatically stops a drive power source of the vehicle when the running condition of the vehicle satisfies a predetermined condition for determining a vehicle stop. When the automatic mode of the brake control section is released or when the diagnostic section outputs a fail signal of the brake control section, the power control section is inhibited to automatically stop the drive power source, so that an unintentional movement of the vehicle caused by an inclination of the road surface and the automatic stop of the drive power source can be prevented.Type: GrantFiled: January 25, 2007Date of Patent: April 12, 2016Assignee: FUJI JUKOGYO KABUSHIKI KAISHAInventors: Yukiya Uchimura, Katsufumi Ichikawa, Tsuyoshi Nakano
