Embodiment Construction

[0023] The present invention realizes the purpose of preventing the vehicle from slipping backward without uneconomical power consumption by changing the amount of torque according to the inclination state of the road surface.

[0024] Figure 1 to Figure 5 Examples of the present invention are shown. Such as figure 1 As shown in , an electrically driven vehicle (hereinafter referred to as a vehicle) such as a hybrid vehicle or an electric vehicle includes a drive motor 1 for driving the vehicle and a control device 2 for controlling the drive motor 1 .

[0025] The control device 2 has a control unit that controls the torque amount of the creep torque generated by the drive motor 1 .

[0026] The control unit 3 is connected to a vehicle speed detection unit 4 for detecting a vehicle speed (hereinafter referred to as a vehicle speed), a brake operation detection unit 5 for detecting a brake operation as a depressed state of the brake pedal, that is, on / off And an accelerato...

Abstract

Provided is a vehicle control device. The control unit is configured to control the torque amount of the creep torque generated by the drive motor for driving the vehicle. The vehicle speed detection unit is configured to detect the vehicle speed. The brake operation detection unit is configured to detect operation of the brake. The road surface state acquisition unit is configured to calculate or detect an inclination angle of the road surface on which the vehicle is parked. The control unit includes a torque amount changing unit configured to, when the vehicle is in a stopped state based on the vehicle speed detected by the vehicle speed detecting unit and the operation of the brake is detected by the brake operation detecting unit, then The torque amount is changed according to the inclination amount of the road surface acquired by the road surface state acquisition unit.

Description

technical field [0001] The present invention relates to a control device for a vehicle, and more particularly, to a control device for a vehicle capable of preventing an electrically driven vehicle such as a hybrid vehicle or an electric vehicle from slipping back on an inclined road surface or the like. Background technique [0002] In a conventional vehicle equipped with an automatic transmission, according to its principle, creep torque is generated to move the vehicle forward even if the driver does not depress the accelerator pedal. [0003] Furthermore, electrically driven vehicles such as hybrid vehicles or electric vehicles employ a structure capable of controlling motor torque so as not to generate creep torque. [0004] However, an electrically driven vehicle is generally set to generate a creep torque, making it uncomfortable for a driver who is experienced in vehicles equipped with automatic transmissions. Generating creep torque when the brake pedal is depresse...
