Problems solved by technology

[0002] In the prior art, the various schemes of active damping anti-shake control for electric vehicles only propose control at the motor controller end, such as band-pass filtering method, rotation speed and wheel speed comparison method, etc., but from the perspective of the whole vehicle, anti-shake The control corresponds to different working conditions (that is, the working state of the equipment under the conditions directly related to its action) requires different anti-shake control measures, and there are also cases of false triggering of the active damping anti-shake control in the prior art. False triggering can cause additional compensation torque to be applied to the driveline causing undesired driveline jerk

Abstract

The invention provides a cross-controller active damping anti-shake control method and system and an electric vehicle. The method comprises the steps that a vehicle control unit recognizes a working condition based on information acquired and processed in the vehicle running process; if the working condition is recognized to need anti-shake control, the vehicle control unit sends out a request signal for anti-shake control to the motor controller, and the request signal lasts for a preset time period; and the motor controller receives the request signal and performs graded active damping anti-shake control on the corresponding working condition. Through cross-controller-platform active damping anti-shake control of the vehicle control unit and the motor controller, the working condition can be recognized more quickly and better, anti-shake control can be carried out quickly, false triggering of active damping anti-shake control is prevented, the working range is safely limited, and theadaptability and universality are high.

Description

technical field [0001] The invention relates to the technical field of active damping and anti-shake control, in particular to a cross-controller active damping and anti-shake control method, system and electric vehicle. Background technique [0002] In the prior art, the various schemes of active damping and anti-shake control for electric vehicles only propose control at the motor controller end, such as band-pass filtering method, rotation speed and wheel speed comparison method, etc., but from the perspective of the whole vehicle, anti-shake The control corresponds to different working conditions (that is, the working state of the equipment under the conditions directly related to its action) requires different anti-shake control measures, and there are also cases of false triggering of the active damping anti-shake control in the prior art. False triggering can lead to the problem of undesired driveline jerk by applying additional compensating torque to the driveline. ...
