Abstract

Embodiments of the present disclosure relate to a vehicle gear shifting method, device, and vehicle; wherein, the vehicle gear shifting method includes: when the vehicle is in a driving state, when a gear shift command is received, judging whether the current torque of the motor is greater than preset torque; if the current torque of the motor is greater than the preset torque, control the motor to perform a torque reduction operation within a preset duration; according to the result information of the motor performing a torque reduction operation within a preset duration, the The vehicle's current gear shifts to the target gear. The technical solution provided by the embodiments of the present disclosure solves the problem that the existing vehicle is prone to stuttering during gear shifting.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of vehicles, and in particular to a vehicle gear shifting method, device and vehicle. Background technique [0002] The vehicle needs to change gears during driving, such as shifting from D gear to R gear, or from R gear to D gear. Usually, after receiving the user's gear shift operation, the target torque is output according to the target gear to control the motor. Quickly switch to the target torque in a short time. However, in the process of shifting the current gear to the target gear, due to the large torque gap between the two gears, the motor speed will change greatly, and it is easy to cause frustration when shifting gears, giving users in the car a certain sense of impact. Reduced vehicle comfort. Contents of the invention [0003] Embodiments of the present disclosure provide a vehicle gear shifting method, device and vehicle, so as to solve the problem that existing vehi...
