Problems solved by technology

However, this invention does not take into account that when the electromagnetic actuator fails, the suspension performance will become very bad, the handling stability and smoothness of the vehicle will deteriorate, and the driving safety will be affected in severe cases; The theme of energy feeding and energy saving should be achieved as much as possible while improving ride comfort
[0007] In addition, the control methods of energy self-supply active suspension actuators in the prior art often focus on a certain aspect of the performance of the active suspension, without the overall performance of the comprehensive energy self-supply active suspension actuator, resulting in the actuator being The active control effect is not obvious during the working process, and the switching speed between the energy feedback mode and the active control mode is too frequent, which causes a serious hysteresis effect in the system and has a great impact on the life of the battery; The control method of the active suspension needs to be improved, and the existing technology cannot make the active suspension in the best state of vibration reduction

Abstract

The invention discloses an electromagnetic energy feeding type vehicle active suspension actuator. The electromagnetic energy feeding type vehicle active suspension actuator comprises an actuator body and an actuator controller. The actuator body comprises an electromagnetic linear motor module and a variable-damping shock absorber module. The electromagnetic linear motor module comprises a plurality of primary coils, a plurality of primary iron chips and a secondary piston rod. The variable-damping shock absorber module comprises a shock absorber piston rod, a piston, a piston cylinder and damping oil. The shock absorber piston rod is a hollow piston rod. The multiple primary iron chips are arranged on the inner wall of the shock absorber piston rod. The primary coils are wound in gaps between the multiple primary iron chips. A throttling hole is formed in the piston. A throttling hole adjustment valve plate and a throttling hole adjustment motor are connected to the piston. The invention further discloses a control method of the electromagnetic energy feeding type vehicle active suspension actuator. The electromagnetic energy feeding type vehicle active suspension actuator is stable and reliable in work and high in energy feeding efficiency; the service life of a vehicle-mounted storage battery can be effectively prolonged, and an active suspension can be made to be in an optimal shock absorbing state.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension systems, and in particular relates to an electromagnetic energy-feeding vehicle active suspension actuator and a control method thereof. Background technique [0002] The performance of the vehicle suspension directly affects the ride comfort and driving safety of the vehicle. As people's requirements for vehicle comfort and safety are getting higher and higher, because the traditional passive suspension converts vibration energy into heat energy in the form of friction and dissipates it, thereby generating damping force to attenuate the vibration of the car, its stiffness damping Once the parameters are determined to be fixed, they cannot change in real time as the vehicle's driving conditions change. It can only ensure that the car achieves the best performance under a specific road state and driving speed, while at the same time it must take into account the ride comfort. Therefo...
