This will bring about a problem, that is, the active suspension parameters adjusted by the proving ground cannot fully cover China's complex road conditions, changing road conditions, and roads that are aggravating damage, which is not conducive to the improvement of ride comfort and handling performance. of
[0003] On the other hand, the information collected by the active suspension system on the road surface is only limited to the use of a single vehicle, but it has not been systematically analyzed and shared with other vehicles. This important information has not been fully utilized to improve the ride comfort of other vehicles. sex and stability

The inventor provides an active suspension control method of an electric vehicle with an intelligent adjusting function. The control method comprises the following steps: S1, acquiring information ofbumpy road conditions, vehicle speed and sprung mass; S2, generating active suspension parameters; S3, adjusting the vehicle active suspension; S4, uploading the information to a cloud system; S5, collecting information of the vehicle position, the vehicle speed and the sprung mass; S6, determining the vehicle position and automatically generating the active suspension parameters; and S7, before the vehicle reaches the bumpy road surface, adjusting the vehicle active suspension. According to the technical scheme, the active suspension can be controlled by adopting different parameters according to the conditions in the vehicle, road conditions in differentiated areas can be controlled, the driving comfort and the operation stability are improved, and meanwhile, various complex and severe bumpy road conditions in front are provided with precautions in advance.
Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to an active suspension control method for intelligent adjustment functions of electric vehicles. Background technique [0002] At present, in the field of electric vehicles, the mainstream active suspensions are adjusted on the proving ground and then locked in the system parameters before mass production. However, the road conditions in China are complex, and the road conditions in each province, city, district, and county are also different. This will bring about a problem, that is, the active suspension parameters adjusted by the proving ground cannot fully cover China's complex road conditions, changing road conditions, and roads that are aggravating damage, which is not conducive to the improvement of ride comfort and handling performance. of. [0003] On the other hand, the information collected by the active suspension system on the road surface is only limited to the use ...
