Automobile and control method and system thereof

Abstract

The invention discloses an automobile and a control method and system thereof. The automobile comprises an air conditioner controller, a gearbox controller and an engine controller. The method comprises the following steps that when the automobile stays in a driving state, whether or not the gearbox controller generates a gear shift signal is judged; if the gearbox controller generates the gear shift signal, information of maintaining an air conditioner state is transmitted to the engine controller; the engine controller generates information for forbidding an air conditioner from being turnedon / off according to the information of maintaining the air conditioner state, and the information for forbidding the air conditioner from being turned on / off is transmitted to the air conditioner controller, so that the air conditioner controller forbids the air conditioner of the automobile from being turned on / off during gear shifting of the automobile conveniently. The control method of the automobile can avoid the situation that unstable influences are caused to an engine when the air conditioner of the automobile and gear shifting of the automobile are changed at the same time; prolonging of the service life of the engine is facilitated, and the automobile and the control method and system thereof are simple and easy to implement.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile control method, an automobile control system and an automobile. Background technique [0002] Ride comfort is an important indicator of car drivability, mainly referring to the subjective comfort of the driver and passengers, and the uncomfortable feelings such as frustration and shaking during driving are the main content of ride comfort evaluation. The quality of ride comfort may be reflected in structural parameters such as vehicle acceleration, engine speed, and clutch shaft speed. [0003] Automobile air conditioner is like a load to automobile power system (especially engine system). Since it is necessary to show the same dynamic and smooth feeling to the outside (driver and passenger), the torque output of the power system is different when the air conditioner is turned on / off, and when the air conditioner is turned on / off, the torque output of the power system T...

AI Technical Summary

Problems solved by technology

[0005] First, limited by working conditions, this technology is only for idling and idling driving conditions, not for normal driving conditions; second, multiple calibrations are required. Calibration of the air compensation amount is carried out separately under different conditions, so it can be seen that re-calibration is required for different models and different working conditions; third, the compensation is single, this technology only describes the air compensation for the load of the air conditioner, and lacks the coordination of multiple loads during driving. The solution to the adverse effects on engine stability and vehicle driving
