Embodiment 1

[0024] Such as figure 1 As shown, a schematic diagram of the motor anti-shake control system of the anti-shake control method of the motor of a hydrogen fuel cell vehicle; the anti-shake control method of the motor is realized based on the vehicle controller, the motor controller, the motor and the reducer; the vehicle control The device is electrically connected to the motor controller; the anti-shake control method includes:

[0025] The vehicle controller recognizes the driver's operation intention by collecting the handbrake status signal, brake depth signal and gear position status signal, and judges whether the vehicle has the conditions to enter the motor anti-shake preparation state according to the driver's operation intention;

[0026] When the vehicle controller judges that the vehicle has the conditions to enter the motor anti-shake preparation state, the vehicle controller collects the data of the accelerator opening signal, brake depth signal, gear status signal,...

Embodiment 2

[0034] The steps in this embodiment are basically the same as in Embodiment 1, except that the first target torque is 2Nm, the first target torque lasts for 7 frames, and the period of each frame is 5ms; the second target torque is 4Nm; the third target torque The torque is -2Nm, the third target torque lasts for 7 frames, and the period of each frame is 5ms; the fourth target torque is -4Nm.

Embodiment 3

[0036] The steps in this embodiment are basically the same as in Embodiment 1, except that the first target torque is 1Nm, the first target torque lasts for 3 frames, and the period of each frame is 20ms; the second target torque is 2Nm; the third target torque The torque is -1Nm, the third target torque lasts for 3 frames, and the period of each frame is 20ms; the fourth target torque is -2Nm.

[0037] What is not involved above is applicable to the prior art.

Abstract

The invention discloses an anti-vibration control method for a motor of a hydrogen fuel cell vehicle. The anti-shake control method includes: the vehicle controller recognizes the driver's operation intention, and judges according to the operation intention whether the vehicle has the conditions for entering the motor anti-shake preparation state; when the conditions for entering the motor anti-shake preparation state are met, the vehicle The controller judges whether the motor needs anti-shake processing according to the collected accelerator opening signal, brake depth signal, gear switch state signal, handbrake state signal and vehicle state information; when it is judged that the motor needs anti-shake processing, the whole The vehicle controller sends a target torque signal to the motor controller, and the motor controller controls the motor to execute the target torque. This method is based on the car's own vehicle controller and motor controller to realize the anti-shake of the motor. The anti-shake control process is simple and does not require additional hardware costs; this method has high reliability and can effectively prevent the motor from shaking and protect the car. Continuity and comfort of driving.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel vehicles, in particular to an anti-vibration control method for a motor of a hydrogen fuel cell vehicle. Background technique [0002] With the popularization of new energy vehicles, more and more motors and reducers are used in various hydrogen fuel cell vehicles, and the reliability and difference of the mechanical structure of the motor and reducer make it possible to control the vehicle under the premise of ensuring the comfort of the vehicle. The difficulty of the motor increases. [0003] In the current state of the art, the anti-shake control technology of the motor is not very mature, and the implementation of the anti-shake control of the motor has problems such as increased cost, complicated process, and low effectiveness and reliability. Therefore, it is necessary to develop a suitable motor anti-shake control technology in a targeted manner. Contents of the invention [0004]...
