AI Technical Summary
Technical Problem
How to improve the shift success rate of new energy vehicles, reduce the risk of gearbox damage, and improve driving comfort.
Method used
By acquiring multiple detection data, the target speed of the drive motor is calculated according to different priorities and accuracies. The high-precision data is used to adjust the motor speed first, ensuring that the speed difference between the dog gear and the gear sleeve is small, reducing wear and noise, and ensuring shift reliability.
Benefits of technology
It improves the shift success rate of new energy vehicles, reduces the risk of gearbox damage, and improves the smoothness and safety of the driving process.

Abstract
The present application provides a vehicle shift control method, device, vehicle, and computer-readable storage medium, relating to the field of vehicle control technology. The method comprises: when the shift condition for switching from the first forward gear to the second forward gear is met, switching the first forward gear to neutral and acquiring multiple detection data; each detection data is used to calculate the motor speed, and each detection data calculates the motor speed in a different manner, and the multiple detection data all carry a priority, and the detection data with a higher priority has a higher accuracy in calculating the motor speed, and vice versa; determining target data from the multiple detection data according to the priority; determining the target speed of the drive motor according to the target data; adjusting the speed of the drive motor according to the target speed, and switching from neutral to the second forward gear when the speed of the drive motor reaches the target speed. The present application can improve the shift success rate of new energy vehicles.
