Abstract
This vehicle control device comprises: a slope movement start assistance unit that maintains a braking force until elapse of a predetermined period since execution of a braking release operation for releasing a braking force applied to the wheels of a vehicle equipped with a motor serving as a power source such that the vehicle does not go down a slope; an acquisition unit that acquires each of the gradient of a road surface on which the vehicle is stopped and the total weight of the vehicle; and a control unit that executes control for causing the motor to generate, in the predetermined period, a threshold torque that corresponds to each of the gradient of the road surface on which the vehicle is stopped and the total weight of the vehicle.
Claims4
A vehicle that includes a motor as a power source for driving wheels, a brake actuator applying brake force to the wheels, and a memory storing executable instructions that, in response to execution, cause a processor to perform operations comprising:
- controlling the brake actuator that maintains braking force until a predetermined period of time elapses after a brake release operation is performed,
- wherein the braking force is maintained so that the vehicle does not slide down on a sloped road, and
- wherein the brake release operation releases the braking force applied to a wheel of the vehicle;
- acquiring a gradient of a road surface on which the vehicle is stopped and an overall weight of the vehicle;
- and
- executing control to cause the motor to generate, in the predetermined period of time, threshold torque in accordance with the gradient of the road surface on which the vehicle is stopped and the overall weight of the vehicle so that the vehicle does not slide down on a sloped road after the predetermined period of time,
- wherein the predetermined period of time is selected from a plurality of predetermined periods of time set to have a plurality of lengths respectively.
