Embodiment Construction

[0028] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

[0029] figure 1 It is a schematic diagram of the gear meshing state when the vehicle is moving forward, figure 2 It is a schematic diagram of the gear meshing state when the vehicle is running backward. In an electric vehicle, the front drive motor and the rear drive motor can be used to simultaneously drive the vehicle. The front drive motor drives the front wheels of the vehicle through the transmission mechanism, and the rear drive motor drives the rear wheels of the vehicle through the transmission mechanism.

Abstract

The invention provides a torque control method and device, a vehicle, electronic equipment and a storage medium. The torque control method comprises the steps that the current speed of the vehicle isdetected; under the condition that the current speed is smaller than or equal to a first speed threshold value, first threshold torque is distributed to a first motor located on the first direction side, first demand torque is distributed to a second motor located on the side deviating from the first direction, the first direction is the direction marked by a current gear, the driving direction ofthe first demand torque is the same as the first direction, and the driving direction of the first threshold torque is opposite to the first direction; and under the condition that a gear switching request is received, second threshold torque is distributed to the second motor, second demand torque is distributed to the first motor, the driving direction of the second demand torque is opposite tothe first direction, and the driving direction of the second threshold torque is the same as the first direction. According to the torque control method, in the gear switching process, irregularity caused by gear gaps can be reduced, and the driving comfort is improved.

Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to a torque control method, device, vehicle, electronic equipment and computer-readable storage medium. Background technique [0002] An electric vehicle refers to a vehicle powered by an on-board power supply and driven by a motor to drive the wheels. Due to the characteristics of energy saving and environmental protection, the prospect of electric vehicles is widely optimistic. Electric vehicles can have both front-drive and rear-drive motors. The front drive motor is connected to the front wheels of the vehicle, and the rear drive motor is connected to the rear wheels of the vehicle. When the vehicle is moving forward, that is, when the gear is in the D gear, the total output torque of the vehicle is a positive torque to drive the vehicle forward. When the vehicle moves backward, that is, when the gear position is R, the total output torque of the vehicle i...
