Abstract

The invention provides a vehicle shake control method and device. The vehicle shake control method comprises the steps of detecting rotational speed extreme values of a vehicle which occur within a preset time period, and counting the occurrence frequency of the rotational speed extreme values, wherein the rotational speed extreme value comprises a rotational speed maximum value and a rotational speed minimum value; according to current operating conditions, the rotational speed extreme values and the occurrence frequency of the rotational speed extreme values of the vehicle, judging whether the vehicle shakes or not; when it is judged that the vehicle shakes, adjusting a filter time coefficient of a motor. Through the vehicle shake control method and device, when the vehicle is under different operating conditions, whether the vehicle shakes due to fluctuation of a rotational speed of the motor or not can be determined, when the vehicle shakes due to the rotational speed of the motor, the filter time coefficient of the vehicle is adjusted, the vehicle is further made to no long shake, and the taking comfort of the vehicle is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a method and device for controlling automobile vibration. Background technique [0002] When the car is running, it will vibrate due to various factors, such as car fluctuations caused by uneven roads, and car vibrations caused by speed fluctuations during motor operation, resulting in poor ride comfort. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a vehicle vibration control method and device to realize whether the vehicle vibrates under different operating conditions, and to control the vehicle after the vehicle vibrates so that the vehicle does not Then shake to improve the ride comfort of the car. [0004] In order to solve the above-mentioned technical problems, the automobile vibration control method provided by the embodiment of the present invention includes: [0005] Detecting the extreme va...
