Problems solved by technology

[0002] Snowy road surface is a common road condition in winter in northern my country. When a car is driving on snowy ground, due to the very low adhesion coefficient of the road, the available road adhesion is very small, and the vehicle is prone to skidding, resulting in vehicle loss. If the driver does not respond properly, it will cause a great safety hazard
In addition, skidding will seriously aggravate the wear and tear of car tires and reduce the service life of tires.
In addition, when braking on snowy ground, the wheels are more likely to lock up and slip due to the slippery ground, which reduces the braking performance of the vehicle.

Abstract

The invention provides an automobile control method and device and an automobile. The automobile control method comprises the steps of obtaining the current working mode of the automobile; when the automobile is currently in a snow mode, controlling an engine to output torque according to a first preset ignition control curve MAP; when the automobile is currently in a non-snow mode, controlling the engine to output torque according to a second preset ignition control curve MAP, wherein when the openings of an accelerator pedal are the same, the torque output by the engine according to the first preset ignition control curve MAP is smaller than the torque output by the engine according to the second preset ignition control curve MAP. According to the automobile control method and device, the automobile is has low possibility of slipping in the snow mode by reducing the output torque so that the automobile is suitable for running under snow conditions; and the running safety of the automobile on the snow roads is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control method, device and automobile. Background technique [0002] Snowy road surface is a common road condition in winter in northern my country. When a car is driving on snowy ground, due to the very low adhesion coefficient of the road, the available road adhesion is very small, and the vehicle is prone to skidding, resulting in vehicle loss. If the driver does not respond properly, it will cause a great safety hazard. In addition, skidding will seriously aggravate the wear and tear of automobile tires and reduce the service life of tires. In addition, when braking on snowy ground, the wheels are more likely to lock up and slip due to the slippery ground, which reduces the braking performance of the vehicle. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a vehicle control method...
