Shift control method and system, vehicle and computer readable storage medium

Abstract

The invention provides a return type vehicle gear-shifting control method and system, a vehicle and a computer readable storage medium. The gear-shifting control method comprises the steps that a position signal of a position where a gear-shifting handle is located is collected in real time; when the position signal changes, the change sequence of the position signal is recorded; when the change sequence is the first preset sequence, the position signal is marked as an invalid signal; and when the collected position signal is the invalid signal, the gear-shifting operation is not executed. According to the technical scheme provided by the invention, even if the position signal transmitted via a CAN bus is discontinuous due to packet loss, the success of the gear-shifting operation is not affected, the gear-shifting control has relatively high reliability and accuracy without increasing the production cost, the corresponding gear-shifting operation can be correctly executed under a variety of service conditions according to the operation of a driver on the gear-shifting handle, the safety level requirement on a gear-shifting device assembly can be appropriately reduced, and further,the production cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, in particular, to a gear shift control method, a gear shift control system, a vehicle and a computer-readable storage medium. Background technique [0002] At present, in the shifting device of electric vehicles, as shown in Table 1, there are usually five gear positions for the return shift handle, which are respectively F1, F2, O, R2, and R1, which correspond to the reverse gear positions in turn. , neutral position, initial position, neutral position and forward gear position, wherein, when changing the gear position, such as switching to reverse gear, the handle is switched from the position of O to the position of F1, and the position of F2 needs to be passed through in the process; similarly, When switching to the forward gear, the handle switches from the O position to the R1 position, and needs to pass through the F1 position during the process. [0003] Table 1 [0004]...

AI Technical Summary

Problems solved by technology

When the D gear is requested again, the signal collected by the VCU may be F1→R1, that is, one or more signals of F2, O, and R2 are lost. If the current strategy is used, the gear cannot be successfully switched
