Embodiment Construction

[0048] In order to make the technical solutions and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] The embodiment of the present application provides a method for controlling the power output of the engine, see figure 1 , the control method includes:

[0050]Step S101 , according to the altitude coefficient of the target vehicle and the intake air temperature of the target vehicle, an optional gear position of the target vehicle is determined, wherein the optional gear position includes at least one of all forward gear positions in the target vehicle.

[0051] For example, in an implementation of the embodiment of the present application, since some people may experience altitude sickness in high-altitude plateau areas, in order to meet the driver's needs when driving in areas with different altitudes, the driver can The altitude ...

Abstract

The invention belongs to the field of automobile electronic control, and particularly relates to an engine power output control method. The method comprises the following steps: determining selectablegears of a target vehicle according to an altitude coefficient of the position where the target vehicle is located and an air inlet temperature of the target vehicle, wherein the selectable gears comprise at least one of all advancing gears in the target vehicle; obtaining the torque loss of an air conditioning system, and determining a driver required torque of the target vehicle according to the gear selected by the driver; and cutting off the air conditioning system of the target vehicle when the sum of the driver required torque and the torque loss of the air conditioning system is greater than a torque threshold and an engine rotating speed is greater than a rotating speed threshold. By using the method, the power output of the engine to the air conditioning system can be controlledin real time, so that the driving comfort of the automobile is improved.

Description

technical field [0001] The invention relates to the field of automotive electronic control, in particular to a control method and device for engine power output. Background technique [0002] The non-independent air-conditioning system in the car is directly driven by the driving power of the car. This type of car only needs one engine, but since the engine mainly drives the car, there is not much power reserved for the air-conditioning system , and the air-conditioning system generally consumes 10%-15% of the power of the engine, which will directly affect the acceleration performance of the car, and then affect the driving comfort of the car. [0003] In order to improve the driving comfort of automobiles, most of the non-independent air-conditioning systems in automobiles are replaced with independent air-conditioning systems. The car is equipped with a special engine to drive the operation of the air conditioner, which can run independently and will not conflict with th...
