Embodiment Construction

[0059] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0060] Before the detailed explanation of the creep control method of the automobile provided in the embodiment of the present application, the application scenario provided in the embodiment of the present application will be introduced first.

[0061]The creep control function of the car means that when the car is started, the brake pedal, hand brake and accelerator pedal of the car are all released, and the car is controlled to start on a flat road or a slope, and maintain a stable speed for driving. This function mainly affects the driving experience when the car is reversed and moved, followed by a car, or parked and started on a small ramp.

[0062] At present, the creep control function of automobiles usually has problems ...

Abstract

The invention discloses an automobile creeping control method and device and a storage medium, and belongs to the technical field of automobile engineering. The method comprises the following steps: when it is detected that an automobile is started, obtaining starting information of the automobile; acquiring control information for controlling the automobile when the starting information of the automobile meets a creeping control condition; and controlling an engine of the automobile based on the control information so as to realize creep control of the automobile. The control information is obtained when the starting information of the automobile meets the creeping control condition, the automobile is subjected to creeping control through the control information, so that the automobile quickly responds to creeping control, and due to the fact that control is conducted through the control information, the noise of automobile creeping control is reduced, and the flameout situation of the automobile in the starting stage is reduced.

Description

technical field [0001] The present application relates to the technical field of vehicle engineering, in particular to a method, device and storage medium for controlling creep of an automobile. Background technique [0002] With the development of technology, there are more and more functions of the car, for example, the creep control function of the car. The creep control function of the car means that when the car is started, the brake pedal, hand brake and accelerator pedal of the car are all released, and the car is controlled to start on a flat road or a slope, and maintain a stable speed for driving. [0003] At present, the creep control function of automobiles usually has problems such as slow creep response, small peak acceleration, poor slope ability, and easy flameout. Moreover, when the creep control is performed on the car, the creep response of the car heat engine is slow and the conduction torque is small. At the same time, when the creep speed is increased,...
