Vehicle control system, vehicle and control method

Abstract

The invention proposes a vehicle control system, a vehicle and a control method. The control system comprises an engine, an air conditioning system comprising an air conditioner and a fan, and a controller for judging if the vehicle is located in an idling state after detecting an air conditioner opening signal and controlling the rotating speed of the engine to raise from the idling rotating speed to the target rotating speed when judging that the vehicle is located in the idling state, wherein when the rotating speed of the engine rises to the target rotating speed, the timing is began; and the air conditioning system is controlled to be started after delaying by a first preset time. According to the vehicle control system of the embodiment of the invention, when the vehicle is in the idling state, the air conditioner is opened, and the rotating speed fluctuation of the engine can be lowered, so that the oil consumption and the emission are reduced to a certain extent, the vehicle taking comfort is enhanced, the engine noise is reduced, and the service life of the engine is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control system, a vehicle and a control method. Background technique [0002] At present, when the car turns on the air conditioner at idle speed, since the torque consumed by the air conditioning system cannot be obtained directly, such an uncertain torque consumption is loaded on the engine. If the engine has insufficient torque control reserve at idle speed, it will directly cause the engine speed to drop If the torque compensation is too large, it will directly cause the engine speed to swell, and the engine will produce large speed fluctuations, which will cause the driver to feel obvious and poor comfort. At the same time, the instability of the speed will lead to deterioration of fuel consumption and emissions. It may even reduce engine life. In addition, due to large fluctuations in speed, the noise will also increase, which will reduce user experience. C...

Problems solved by technology

[0002] At present, when the car turns on the air conditioner at idling speed, since the torque consumed by the air conditioning system cannot be obtained directly, such an uncertain torque consumption is loaded on the engine. If the torque compensation is too large, it will directly cause the engine speed to bulge, and the engine will produce large speed fluctuations, which will cause the driver to feel obvious and the comfort is poor. At the same time, the instability of the speed will lead to the deterioration of fuel consumption and emissions.

It may even reduce the service life of the engine

In addition, due to large fluctuations in speed, the noise will also increase, reducing user experience
