A vehicle selects a parking position when a state in which a P range button () is operated overlaps a state in which an N range button () is operated. Thereafter, the vehicle maintains the parking position when the operation of P range button () is released and switched to the state in which N range button () is operated. This allows the vehicle to suppress the selection of a shift position that is different from the intention of the driver.

Control method for vehicle and control device for vehicle

An automatic parking control device includes an automatic parking controller that carries out automatic parking control, and a park-by-wire controller in which a park lock is automatically engaged when automatic parking is completed at a target stopping position by the automatic parking control. The park-by-wire controller determines whether a system abnormality would occur, in which the park-by-wire system does not operate normally during the automatic parking control. The automatic parking controller prohibits the starting of the automatic parking control upon determining that the system abnormality would occur before the automatic parking control is started.

Automatic parking control method and automatic parking control apparatus for vehicles

A vehicular power supply failure time safety measures control apparatus for a vehicle equipped with an electric park lock mechanism includes a means to detect a power supply failure in a park lock power supply, and a means to examine an electric storage state of the park lock power supply after the time of the power supply failure. The control apparatus further includes a park lock means to lock rotation of the wheel by operating the park lock mechanism when the electric storage state of the park lock power supply approaches a lower limit of the electric storage state ensuring the operation of the park lock mechanism.

Control device for use in vehicle, adapted to control safety measures against electric power supply failure

When a traveling drive system is activated at a time tin response to a turning of an ignition switch to an ON state at a time t, a request of P/N inhibit (a park lock release inhibit) from an electrically operated motor controller vanishes. Therefore, originally, according to an execution of a park lock release, the vehicle is started in response to a holding of a D position of a shifter. However, in a case where a park lock release inhibit state occurs at a time immediately before time tand the shifter is at the D position at time t, a present shift inhibit flag takes over the park lock inhibit state at the time immediately before tuntil a time tat which the shifter returns to a home (H) position so that the above-described start of the vehicle is prevented.
