Description
Technical field
The utility model belongs to technical field of automotive electronics, specially refers to the electronic control system of active suspension.
Background technology
Along with the progress of AE, decision travelling comfort and handling automotive suspension technology have obtained extensive attention and in-depth study.Automotive suspension is the general name that connects whole part and assemblies between vehicle body and the wheel, mainly is made up of spring, shock absorber and guiding mechanism three parts.When running car on different road surfaces and when making wheel be subjected to mechanical vibration, because draft hitch has been realized the resilient mounting between car body and the wheel, the dynamic load and the vibration of car body and wheel have been suppressed, have reduced effectively, thereby guarantee the ride comfort of running car and the stability of controlling, reach the purpose that improves average ground speed.
Automotive suspension comprises passive suspension and active suspension, and the control of passive suspension is mainly finished by mechanical mechanism, and the quantity of information of systems exchange seldom directly connects by common wire harness and just can satisfy communication need; Active suspension is because relate to more controller and sensor, and its control policy is also comparatively complicated, so its controller need carry out data exchange with more ECU (Electrical Control Unit), and finishes control policy by a large amount of vehicle body dynamic motion signal of sensor acquisition.The electronic control system of tradition active suspension need define a large amount of electric interfaces and relevant wire harness, and the connection of its signal wire (SW) is very complicated, and cost is also higher, and extensibility and stability are all relatively poor, the fault rate height.
The utility model content
The purpose of this utility model is to propose a kind of simple in structure, stable performance, expand the electronic control system of active suspension easily.
The electronic control system of active suspension of the present utility model comprises electronics suspension controller, suspension modes select switch, engine controller, brake controller, steering wheel angle sensor, car body controller and the acceleration pick-up of control executing mechanism work, described electronics suspension controller links to each other with car body controller, engine controller, brake controller, steering wheel angle sensor by high-speed CAN bus, and described electronics suspension controller links to each other with acceleration pick-up, suspension modes select switch.
The order of electronics suspension controller reception suspension modes select switch changes the mode of operation of suspension, and control executing mechanism work, concrete principle of work is as follows: in driving, electronics suspension controller is by the instant vehicle speed signal that receives from brake controller of high-speed CAN bus, the angular signal of wheel speed signal and steering wheel angle sensor, the tarnsition velocity signal, and the engine status signal of engine controller, the accelerator open degree signal, the torque request signal, moment of torsion output signal etc., gather vehicle body dynamic motion information by acceleration pick-up again, after above-mentioned information processing, drive the suspension dash pot valve of actuating unit, come dynamic adjustments to hang the coefficient of damping, improve travelling comfort and travel safety.
Described car body controller also links to each other with instrument by low speed CAN bus, in driving, electronics suspension controller can send to car body controller to the mode of operation of current suspension control system and fault status information by high-speed CAN bus, car body controller is forwarded to low speed CAN bus, after instrument receives, the mode of operation of current suspension control system and faulty condition are presented on the gauge panel, make the client can in time understand the service condition of current suspension control system, increased the reliability of travel safety and system.In above-mentioned working process, car body controller has played the effect that high-speed CAN bus and low speed CAN bus are coupled together, this be because this car body controller self integrated high-speed CAN bus gateway and low speed CAN bus gateway function.
Described car body controller also links to each other with air-conditioner controller by low speed CAN bus, the effective id signal of ambient temperature signal that air-conditioner controller sends and ambient temperature, send in the high-speed CAN bus by car body controller, electronics suspension controller receives these information and handles, and realizes its control policy.
Described acceleration pick-up comprises body-acceleration sensor and wheel acceleration sensor, so that the information of acceleration/accel is more comprehensive.
The electronic control system of active suspension of the present utility model utilizes car body controller that the car load network is split into high speed power and chassis CAN network and low speed vehicle body CAN network, make that network information transmitted amount is bigger, and make things convenient for the function expansion of system, thereby avoided the system load rate height of traditional single channel network, the shortcoming that extensibility is low, stability is low, realized the optimization of resource and shared, improved the real-time of system, make the performance of active suspension more stable, intelligent degree is higher.
