Abstract

The invention provides a vehicle control system and a control method thereof. TheA control method comprises the following steps that a first controller acquires a demand torque according to the position of a throttle gear, calculatinges a target output torque of an engine according to the demand torque and sendings the target output torque of the engine to a second controller; the second controller calculates an actual output torque of the engine according to the target output torque of the engine, and the engine outputs a torque according to the actual output torque of the engine; a third controller obtains an actual monitoring torque according to a running condition of a power output shaft and provideings the actual monitoring torque to the second controller; the second controller calculates a self-learning torque of the engine according to the actual output torque of the engine and the actual monitoring torque and obtains the actual output torque of the engine according to the self-learning torque of the engine when calculating the actual output torque of the engine.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a vehicle control system and a control method thereof. Background technique [0002] Even based on changes in the same vehicle operating conditions (operating conditions of accelerator pedal depression amount, driving conditions of vehicle speed), the acceleration obtained by the vehicle is also greatly different due to the output torque characteristics of the driving power source. The actual situation is that the driver passes the vehicle. The expected acceleration cannot be obtained due to changes in the driving conditions (the driving conditions of the accelerator pedal depression amount and the running conditions of the vehicle speed). [0003] Therefore, it is necessary to design a vehicle control system and its control method that accurately responds to the output torque. Contents of the invention [0004] The purpose of the present invention is to provide a vehicle c...
