Embodiment Construction

[0020] Examples such as figure 1 As shown, a method for anti-vibration control of tooth surfaces of electric vehicles is applied to electric vehicles. To realize this method, the drive motor, gear pair, accelerator pedal, and vehicle controller in the electric vehicle are required. Wherein, the specific structure and connection relationship of the driving motor, the gear pair, the accelerator pedal, and the vehicle controller are all existing technologies, and will not be repeated here. The tooth surface reversing anti-vibration control method disclosed in this embodiment is aimed at the reversing control during driving, including: when the vehicle controller judges that the vehicle needs to switch from driving mode to energy recovery or from energy recovery to driving mode , start the tooth surface commutation control: firstly, before the tooth surface commutation, reduce the torque conversion slope until the torque is zero; then in the commutation, send out a small reverse z...

Abstract

The invention discloses a tooth surface reversing anti-shake control method for an electric vehicle. The tooth surface reversing anti-shake control method for the electric vehicle comprises the stepsof a reversing signal obtaining step, a torque obtaining step, a reversing step, a step of processing a torque after reversing and a step of judging a torque value after reversing; and the tooth surface reversing anti-shake control method for the electric vehicle further comprises the steps of judging whether an output torque processed in the step of processing the torque after reversing reaches atorque preset value after reversing or not; and if so, finishing reversing and returning to the reversing signal obtaining step; and otherwise, returning to the step of processing the torque after reversing. According to the tooth surface reversing anti-shake control method for the electric vehicle, tooth surface reversing is realized during smoother running, the tooth surface reversing anti-shake control method for the electric vehicle is more in line with characteristics of pure electric logistics vehicles, and the comfort of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the fields of electric vehicle reversing and the like, in particular to a control method for anti-vibration control of electric vehicle tooth surface reversing. Background technique [0002] In the current general environment, new energy vehicles are becoming more and more popular, and among them, pure electric vehicles are being used more and more in various industries due to their relatively simple technical difficulties and the cost advantage of a relatively simple vehicle structure. Logistics vehicles are one of them. [0003] The mainstream structure of the pure electric logistics vehicle powertrain is that the drive motor transmits power to the wheels through the primary speed ratio and then the final reducer; compared with the traditional logistics vehicle using an internal combustion engine, the pure electric logistics vehicle removes the clutch and drives the motor. It is rigidly connected with the main reducer; the a...
