Abstract
A SBW-ECU includes: a P unreleasable region determination portion configured to determine whether a road surface slope Sr at a vehicle position and an output voltage Volr of an auxiliary battery fall within a predetermined parking lock unreleasable region or not; and a P release request rejection portion configured to reject a P release request in a case where P release request rejection conditions to are all satisfied, including a fact that the P unreleasable region determination portion determines that the road surface slope Sr at the vehicle position and the output voltage Volr of the auxiliary battery fall within the parking lock unreleasable region (the P release request rejection condition (c) is satisfied).
Claims8
A parking lock control device for a vehicle,
- the parking lock control device being configured to change a parking lock mechanism to a non-parking lock state by an electric actuator using a first power supply as a power supply, in response to a change request to change a state from a parking lock state to the non-parking lock state,
- the parking lock control device comprising
- an electronic control unit configured to
- determine whether a road surface slope at a vehicle position and an output voltage of the first power supply are within a predetermined parking lock unreleasable region or not, and
- reject the change request when the electronic control unit determines that the road surface slope at the vehicle position and the output voltage of the first power supply are within the parking lock unreleasable region.
