Abstract

The invention relates to a car rollover-prevention system and a control method. The car rollover-prevention system comprises a car frame, a first suspension and a second suspension; the first suspension and the second suspension are each connected with the car frame through a damping spring; the first suspension and the second suspension are in rigid connection with a first wheel and a second wheel respectively. The car rollover-prevention system further comprises a first linear motor connected between the car frame and the first suspension and a second linear motor connected between the car frame and the second suspension; a first sensor and a second sensor are each arranged below the car frame; a third sensor is arranged below the car frame; a first controller is used for receiving distance signals transmitted by the first sensor and transmitting moving signals to the first linear motor; a second controller is used for receiving distance signals transmitted by the second sensor and transmitting moving signals to the second linear motor; a third controller is used for receiving an inclined angle value transmitted by the third sensor and transmitting moving signals to the first linear motor and the second linear motor.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, and in particular relates to a vehicle anti-rollover system and a control method. Background technique [0002] Suspension is an important structural and functional part of the vehicle, which has a great influence on the overall performance of the vehicle. Vehicle suspension can be divided into passive suspension, semi-active suspension and active suspension according to its working principle. Passive suspension is mainly composed of springs, shock absorbers, etc. The shock absorber consumes and the spring buffers the vibration energy between the vehicle axle and the body mass to obtain the vibration reduction effect, but the fixed stiffness and damping are difficult to meet various vibration reduction requirements . Ordinary semi-active suspension is to transform the shock absorber with constant damping value of passive suspension into a damping element with real-time adjustable dampin...
