Problems solved by technology

[0004] However, after the emergency braking of a vehicle with automatic start-stop function, the engine will automatically shut down and the engine will be turned off. After the automatic shutdown, the driver needs to restart the engine before starting the vehicle again. The movement often occurs when the vehicle is driving on the road. If the vehicle cannot be moved in time, it will bring many potential safety hazards.

Abstract

The invention relates to an engine control method and system and a vehicle comprising the engine control system. The engine control method is applied to the vehicle with the automatic starting and stopping function. The engine control method comprises the steps that it is detected that a brake pedal of the vehicle is in the pedaled state, and the current related running parameters of the vehicle are obtained; whether the related running parameters at least meet one emergency braking criterion in a preset emergency braking criterion set is judged; and if the related running parameters at least meet one emergency braking criterion in the preset emergency braking criterion set and the current vehicle speed of the vehicle is smaller than the preset vehicle speed threshold value, stopping of a vehicle engine is restrained. Potential safety hazards caused by untimely vehicle moving due to automatic stopping after the vehicle with the automatic starting and stopping function is emergently braked can be reduced or avoided.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to an engine control method and system, and a vehicle including the engine control system. Background technique [0002] With the continuous development of the automobile industry, automobiles have become the main means of transportation for people to travel. When the driver is driving the vehicle, if there is an emergency, the driver can quickly and correctly use the brakes to stop the vehicle within the shortest distance, which is called emergency braking. [0003] In response to increasingly stringent fuel consumption regulations, more and more vehicles are equipped with an automatic start-stop function. Automatic start-stop refers to automatically controlling the shutdown and start-up of the vehicle engine, while reducing unnecessary fuel consumption, reducing emissions, and improving fuel consumption. economy. The automatic start-stop function is mainly suitable for waiting for...
