Based on the vehicle gear shift handle control system, the invention also provides a vehicle gear shift handle control method, as shown in fig. 2, the method comprises the following steps:
acquiring information of a driver operating a gear shifting handle, and acquiring operation information through a handle gear control module;
detecting the position of a gear shifting handle in real time, detecting whether the gear position of the gear shifting handle is pushed in place or not when detecting that a driver requests a gear, and identifying the current gear if the gear position is pushed in place to judge the driving mode of the vehicle;
if the alarm is not in place, the buzzer alarms;
if the automatic mode is selected, judging the current state information of the crawling selection module and the economic/power mode switching module;
if the crawling mode is started, judging whether the crawling mode is a neutral gear;
if the gear is neutral, judging the type of a starting mode and sending current gear information to a gearbox controller, if the gear is not neutral, judging the starting mode after returning to the neutral, and sending the current gear information to the gearbox controller; enabling the gearbox controller to execute according to the gear information selected by the driver;
the starting mode comprises the following steps: crawling starting, medium idle speed starting and high idle speed starting.
The crawling mode is suitable for special working conditions such as heavy-load climbing and the like; the crawling starting is suitable for the low-speed vehicle moving working condition in a field, the vehicle can be started without stepping on an accelerator, the gear shifting can be performed in a low gear area in the running process, and the vehicle speed can be controlled only by braking; in the medium and high idle speed starting mode, the rotating speed of an engine is increased to be medium and high speed in advance and then is combined with a clutch so as to improve the starting performance, and the clutch is used carefully so as to avoid influencing the service life of the clutch.
In the present invention, the above process is performed based on a manual mode. In the operation process, if the operating handle breaks down, the emergency mode function is realized. After the emergency mode is activated, the economy/power mode switching module moves forwards and can drive forwards; the function selection module is in neutral, namely the function selection module can return to neutral by pressing; the crawling selection module can realize backing and display corresponding functions on the instrument. After the vehicle enters forward, the economy/power mode switching module is in gear-up, and the crawling selection module is in gear-down.
In the method related by the invention, if the crawling mode is not selected, the current gear information is sent to a gearbox controller;
if the mode in the economy/power mode switching module is selected, judging a driving mode, and sending gear information of the selected mode to a gearbox controller;
the driving modes include: an economy mode, an economy coasting mode, and a power mode;
and if the economy/power mode switching module is not selected, the economy mode is not started by default, and the current gear information is sent to the gearbox controller.
The control system of the economic mode (E) selects a proper gear to enable the engine to operate in the most economic area, so that the economy is better, and the oil consumption is lower; in the economic sliding mode (E +), a driver does not step on an accelerator and brake in the driving process of the vehicle, the current road condition is a level road or a small slope, and the system automatically enters a neutral gear; when the driver steps on the accelerator (or the exhaust brake, the retarder and the E/P switching are performed to exit the E +) or the ramp is enlarged, the system is automatically engaged in a proper gear, and the neutral gear slides to exit. The economy is best, and the oil consumption is lowest. The power mode (P) control system selects the appropriate gear to maximize power production by the engine. The P mode or carefree function is recommended to be used under the working conditions of full-load mountain roads, soft roads and plateaus.
In the method, two driving modes can be realized: an automatic mode and a manual mode. The automatic mode driver does not need to carry out any gear shifting action, and the system automatically takes over the clutch; in the manual mode, a driver operates a gear shifting handle, gear shifting is carried out according to the driving desire of the driver, and the driver does not need to step on a clutch.
In the manual mode, when a driver operates, the system judges whether the current gear is a forward gear or a reverse gear;
if the gear is reverse gear, judging the vehicle state;
if the gear is in a parking state, the currently selected gear information is sent to a gearbox controller;
and if the gear is not in the parking state, executing a parking instruction, and sending the selected gear information to the gearbox controller. Namely, the vehicle is stopped first, and then the corresponding control mode is executed.
When a driver operates, the driver reselects a gear;
if the gear is a forward gear, judging whether to start a crawling selection module;
if the crawling selection module is started, judging whether the gear is neutral or not;
and if the crawling selection module is not started, sending current gear information to the gearbox controller.
When a driver operates, the driver reselects a gear;
if the gear is a forward gear, acquiring a range gear switch state and a shift switch state;
