Problems solved by technology
However, in view of the insufficient anti-pitch performance of the suspension, in the traditional structure, adjusting the angle of the cross arm in the side-view geometry or increasing the suspension bias frequency are two common solutions to solve the excessive pitch angle of the car body under the pitching state of the racing car. But both solutions have limited practical impact and complicate the design process
Therefore, there is still no effective suspension technology to fill the gap in the control of the body pitch attitude of the formula car under extreme conditions.

The invention belongs to the technical field of automobiles, and particularly relates to an electric control hydraulic interconnection suspension system for a formula car, and a control method thereof. The system comprises a data processing system, an actuator, a hydraulic interconnection suspension mechanical device and a formula car suspension system; the data processing system is connected withthe actuator; the actuator is connected with the hydraulic interconnected suspension mechanical device; and a hydraulic pipeline in the actuator is fixedly connected with the formula car suspension system. An electric control anti-pitching hydraulic interconnected suspension system is introduced based on the double-wishbone independent suspension design of the formula car, and interconnection suspension system arrangement and control method design are carried out on the formula car suspension structure, so that the car body pitching posture control capacity of the formula car under an emergency braking / acceleration working condition is improved, the influence on the actual performance of an aerodynamic device is reduced, and the formula car control stability is improved.
Description
technical field [0001] The invention belongs to the technical field of automobiles, and specifically relates to an electronically controlled hydraulic interconnected suspension system and a control method thereof for formula racing cars. Background technique [0002] With the continuous development of the suspension technology of formula racing cars, the suspension system in the field of domestic formula student racing cars has gradually completed the transformation from the traditional "double damper-spring double wishbone independent suspension with stabilizer bar" to "third spring independent Suspension", "third damping independent suspension", "single spring-double damping independent suspension" and many other changes in suspension forms. However, in view of the insufficient anti-pitch performance of the suspension, in the traditional structure, adjusting the angle of the cross arm in the side-view geometry or increasing the suspension bias frequency are two common solu...
