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.

Claims6

Dependent claims

A control device for a vehicle, the control device comprising:

a slope starting assistance section 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 including a motor as a power source does not slide down on a slope road, and the brake release operation is an operation for releasing the braking force applied to a wheel of the vehicle;
an acquisition section that acquires a gradient of a road surface on which the vehicle is stopped and an overall weight of the vehicle;
and
a control section that executes 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.
