Problems solved by technology
[0003] However, the usual SUV models have the following inherent problems: the body shakes greatly when braking, the body rolls sharply when turning sharply, and the body nods severely when braking in an emergency, etc. These problems will lead to stable handling of the vehicle. Reduced performance and comfort, bringing users a bad driving experience; however, these problems are all problems of the passive damping shock absorption system, which are difficult to overcome from the design principle

The present application discloses a shock absorber control method, the method includes: obtaining vehicle shaking roll speed and vehicle running parameters; determining a shock absorber control strategy adapted to the current driving state according to the vehicle running parameters, the shock absorber The control strategy is used to calculate the suppression damping value correspondingly according to the obtained vehicle shaking and rolling speed; then, output the control current to each shock absorber through the constant current source module to control each shock absorber to generate its corresponding suppression damping value, Applied to the body of the vehicle to reduce the amount of shaking and / or roll of the vehicle. In the above method, by applying the corresponding damping force to each shock absorber, the shaking and / or rolling phenomenon generated by the current driving state of the vehicle is correspondingly suppressed, thereby improving the driving experience of the user.
Description
technical field [0001] The present application relates to the technical field of vehicle control, in particular to a shock absorber control method, device and system. Background technique [0002] Nowadays, sport utility vehicle (sport / suburban utility vehicle, SUV) is favored by more and more consumers. [0003] However, the usual SUV models have the following inherent problems: the body shakes greatly when braking, the body rolls sharply when turning sharply, and the body nods severely when braking in an emergency, etc. These problems will lead to stable handling of the vehicle. Sex and comfort are reduced, which brings bad driving experience to users; but these problems are all problems of passive damping shock absorption system, which are difficult to overcome from the design principle. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the present application provides a shock absorber control method, which can effectively sol...
