Problems solved by technology
[0003] In the prior art, when a new off-line automatic transmission is assembled for the first time, the shifting of the transmission may be uneven and shocking when the vehicle is first driven. This is due to the limitation of the manufacturing process and the valve of the transmission oil circuit. There is no guarantee that every gearbox can meet the design requirements due to the difference of body
Due to the different manufacturing tolerances of each gearbox, it can lead to poor shifting smoothness of the entire gearbox

The invention provides a gearbox self-learning state entering method and device, and relates to the field of gearbox inspection. When the gearbox self-learning state entering method and device meet the factory self-learning condition, a control command is sent to a diagnostic tool through an automatic gearbox controller, and the control command comprises a limiting value for limiting an accelerator pedal; then, a factory self-learning command and the control command to an engine management system through the diagnostic tool; and finally, the engine management system selects the minimum value of the actual opening degree of the accelerator pedal and the limiting value which contained in the control command and is used for limiting the accelerator pedal to limit the opening degree of the accelerator pedal. According to the gearbox self-learning state entering method and device, when a driver is in the actual self-learning state, clutch self-learning is completed by limiting the opening degree of the accelerator pedal, accordingly, the driver can accurately control the opening degree of an accelerator, and the gear shifting smoothness of the whole gearbox is improved.
Description
technical field [0001] The invention relates to the field of gearbox inspection, in particular to a method and device for entering a gearbox self-learning state. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into two types: manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; while the automatic gearbox AT is a hydraulic torque converter. It is composed of gear, planetary gear, hydraulic pitch change system and hydraulic control system. Variable speed and torque are achieved through hydraulic transmission and gear combination. [0003] In the prior art, when a new off-line automatic transmission is assembled for the first time, the shifting of the transmission may be uneven and shocking when the vehicle is first driven. This is due to the limitation of the manufacturing process and the valve of the transmissio...
