Abstract

The invention provides an automobile gear shifting control method and device, a controller and an automobile. The method comprises the following steps that when the gear shifting operation is detected, the current vehicle speed of the automobile is acquired; the current running control signal of the automobile is acquired according to the current vehicle speed; and whether the gear shifting operation is a gear error operation is determined according to the current operation control signal. According to the method, the problem that the condition in an existing electric vehicle that the vehiclespeed is low in the gear error operation judgment logic is not considered is solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile shift control method, device, controller and automobile. Background technique [0002] With the rapid development of automobile technology, new energy vehicles, mainly electric vehicles, have gradually opened up the market and entered people's lives. Different from the multi-speed gearbox and single-speed reducer used in traditional fuel vehicles, electric vehicles generally only use a single-speed reducer, and because the motor has better operating characteristics, it can achieve forward and reverse rotation, torque The response speed is faster than the internal combustion engine, and the electric vehicle has the advantages of convenient gear shifting, low noise and quick power response. [0003] However, if the shift logic design of electric vehicles is improper, such as some working conditions where the accelerator pedal is accidentally stepped on to shift g...
