The invention discloses a heavy truck AMT curve gear selection method, device and equipment and a storage medium, and the method comprises the steps: activating a curve gear selection function when a heavy truck meets an activation condition of curve gear selection; obtaining current vehicle parameters and road parameters of the heavy truck, and determining corresponding downshift regulation and control data according to the vehicle parameters and the road parameters; according to the downshift regulation and control data, downshift rotation speed limiting operation is conducted on the AMT gearbox of the heavy truck, fast downshift can be conducted according to the activation condition, a correct gear is selected in the heavy truck curve process, the speed and efficiency of downshift of the heavy truck curve gear are improved, engine flameout is avoided, and the service life of the heavy truck curve gear is prolonged. The curve gear downshift accuracy and timeliness are improved, and the driving experience of a driver is improved.
Description
Technical field [0001] The present invention relates to the field of automotive technology, and more particularly to a heavy card AMT curve gear selection method, apparatus, device, and storage medium. Background technique [0002] Due to the large number of heavy card AMT load range, the single-point connection of the tractor of tractor and the head of the car has led to a significant increase in vehicle resistance during the overlying process. Once the downs is not timely, it is easy to cause frequent dimming, and forced to stop the vehicle, and may even Leading the engine flameout, seriously affecting the driving experience, and there is no better solution. Inventive content [0003] The main object of the present invention is to provide a heavy card AMT curve gear selection method, device, device, and storage medium, aimed at solving the prior art in-vehicle cars over-curve, and it is easy to cause the engine to turn off, affect the driver. Technical issue of driving experie...
