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

A control device for a lock-up clutch includes a control unit, an abnormality determination unit, a release control unit and a prohibition unit. The control unit is configured to control an engagement state of a lock-up clutch, and to perform a slip lock-up control by performing a feedback control of an engagement hydraulic pressure to be a first slip amount during coasting. The abnormality determination unit is configured to determine an abnormality when a state continues with a slip amount being equal to or greater than a second slip amount. The release control unit is configured to release the lock-up clutch when the abnormality is determined. The prohibition unit is configured to allow the control unit to raise the engagement hydraulic pressure by a prescribed pressure, and to prohibit determination by the abnormality determination unit, when the transmission ratio is downshifted during coasting while the slip lock-up control is performed.
