Problems solved by technology

However, this method for controlling vehicle cruising is only applicable to vehicles powered by engines, and when the vehicle is a hybrid vehicle, the cruising of the hybrid vehicle cannot be realized. Therefore, a control method that is also applicable to hybrid vehicles is urgently needed. Vehicle Cruise Method

Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] figure 1 It is a flow chart of a method for controlling vehicle cruising provided by an embodiment of the present invention. The execution subject of the method may be a control terminal, such as figure 1 As shown, the method includes:

[0042] Step 101: When it is detected that the vehicle reaches the preset cruising condition, according to the cruising speed of the vehicle, determine the virtual accelerator pedal opening corresponding to the cruising speed;

[0043] Step 102: Determine the target wheel end torque of the vehicle according to the virtual accelerator pedal opening and the current vehicle speed of the vehicle;

[0044] Step 103: Determine the target engine torque of the engine and the target motor torque of the ...

Abstract

The invention discloses a method and device for controlling vehicle cruise, and belongs to the technical field of vehicle electronic control. The method comprises the following steps of when a vehicleis detected to achieve a preset cruise condition, according to the cruise speed of the vehicle, determining the opening degree of a virtual accelerator pedal corresponding to the cruise speed; according to the opening degree of the virtual accelerator pedal and the current speed of the vehicle, determining a target wheel end torque of the vehicle; according to the target wheel end torque and a speed ratio signal of the vehicle, determining the engine torque of an engine and the motor torque of a motor in the vehicle; and adjusting the current torque of the engine to be the engine torque, andadjusting the current torque of the motor to be the motor torque, so that the purpose that the current speed of the hybrid vehicle is controlled to achieve the cruise speed, is realized.

Description

technical field [0001] The invention relates to the technical field of vehicle electronic control, in particular to a method and device for controlling vehicle cruising. Background technique [0002] With the development of vehicle electronic control technology, the control terminal in the vehicle can electronically control the cruising of the vehicle. Vehicle cruising means that the vehicle automatically maintains a fixed speed without the driver stepping on the accelerator pedal during driving. For example, when the vehicle is driving on the expressway for a long time, the control terminal can control the vehicle to perform the vehicle cruise state, thereby reducing the driving fatigue of the driver. [0003] The control process of the control terminal to control the vehicle cruise is as follows: the control terminal adjusts the fuel supply of the engine in real time according to the vehicle speed set by the driver, combined with factors such as road conditions and vehicle...
