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

A vehicle-used controller is provided; a control unit controls a torque value of a crawl torque generated by a driving motor driving the vehicle; a vehicle speed detection unit is configured to detect vehicle speed; a brake operation detection unit is configured to detect brake operation; a road state obtaining unit is configured to calculate or detect a tilting angle of the road with parking cars; the control unit comprises a torque value changing unit; when the vehicle speed detected by the vehicle speed detection unit is in the stop state, and the brake operation is detected by the brake operation detection unit, the torque value can be changed according to the road tilting value obtained by the road state obtaining 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...
