Abstract: A smart ECU switches on a traveling power supply on condition that a portable device of a user is present in a start area set in a vehicle. The smart ECU normally determines whether the portable device is present in the start area based on reception strength of a signal from the portable device at a first communication device that is a specific BLE communication device disposed in the vehicle. However, in a case where a failure is detected in the first communication device, the smart ECU determines that the portable device is present in the start area when reception strength at a second communication device, which is another BLE communication device set in advance as a substitute device, is equal to or greater than a predetermined value.

Abstract: A vehicle control apparatus determines a location of a key device through wireless communication with the key device. The vehicle control apparatus is configured to perform a wireless authentication process of determining whether a communication partner is the key device and a location determination process of determining whether the communication partner is present in a vehicle, and to identify an authentication failure reason that is a reason why the communication partner has failed to be determined as the key device.

Abstract: The sealing member includes a first sealing part and a second sealing part and a joining part connecting together the first sealing part and the second sealing part. The first sealing part extends to surround a peripheral edge of the first opening hole on the main body inner peripheral surface side. The second sealing part extends to surround a peripheral edge of the second opening hole on the main body inner peripheral surface side. The joining part is placed at a position where a mutual interval between the first sealing part and the second sealing part is the smallest in the circumferential direction. Each of the first joining end portion and the second joining end portion of the joining part is pressed outward in the valve radial direction by the valve body outer peripheral surface to be resiliently deformed.
