Problems solved by technology

[0004] An object of the present invention is to set the exit condition for exiting the navigation function by using the steering wheel angle in the process of exiting the navigation function of the existing vehicle, so as to solve the problem of not setting the exit condition for exiting the navigation function by using the steering wheel angle in the prior art. The problem that causes the vehicle to accelerate unsafely after driving out of the curve

Embodiment Construction

[0020] see figure 1 , the method for exiting the vehicle navigation function of the present invention mainly includes the following steps:

[0021] S1. After the vehicle enters the navigating function, if the engine management system detects that the vehicle's preset index items meet the exit conditions of the navigating function, it sends an exit command to the transmission control unit to exit the navigating function, and the preset index items include: steering wheel angle;

[0022] S2. After the transmission control unit receives the exit command triggered by the steering wheel angle, if it detects that the engine speed is synchronized with the output shaft speed, it controls the clutch to close to exit the sailing function.

[0023] That is, if figure 1 As shown, in the method for exiting the navigation function of the vehicle in the present invention, first, after the vehicle enters the navigation function, if the engine management system (EMS) detects that the preset i...

Abstract

The invention provides a method for quitting a vehicle navigation function. The method comprises the following steps that after a vehicle enters a navigation function, if an engine management system detects that preset index items of the vehicle meet the quitting condition of the navigation function, a quitting instruction for quitting the navigation function is sent to a transmission control unit, and the preset index items comprise the steering wheel rotating angle; and the transmission control unit controls the clutch to be closed so as to quit the navigation function if detecting that therotating speed of the engine is synchronous with the rotating speed of the output shaft after receiving a quit instruction excited by the steering wheel angle. According to the method for quitting thevehicle navigation function, the quitting condition that the vehicle quits the navigation function through excitation of the steering wheel corner is set, and it is guaranteed that acceleration is safer after the vehicle drives out of the curve.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a method for exiting a navigation function of a vehicle. Background technique [0002] The internal combustion engine vehicle power transmission system is roughly composed of mechanical parts assembly such as engine, transmission and drive shaft, as well as electronic control units such as the engine management system (EMS) that controls the engine and the transmission control unit (TCU) that controls the automatic transmission. As we all know, an internal combustion engine vehicle burns fuel through the engine, converts chemical energy into mechanical energy, and overcomes various resistances to achieve driving functions. If the car is always running at a constant speed, the greater the resistance, the more fuel will be consumed. Conversely, the less drag, the less fuel is consumed. Therefore, in order to improve fuel economy and reduce fuel consumption rate, when the...
