Embodiment Construction
[0044] The invention provides an integrated control device for an automobile active suspension and an electric power steering system. Such as figure 1 As shown, the device includes a data acquisition module, an A / D conversion module, an electric control unit, and an actuator. The actuator includes a stepping motor and a booster motor. The data acquisition module is sequentially connected with the A / D conversion module and the electric control unit, and the electric control unit is connected with the stepper motor and the booster motor through communication.
[0045] The data acquisition module includes an acceleration sensor, a torque sensor, and a Hall current sensor. The Hall current sensor is arranged on the fixed platform of the active suspension, and is used in the electric power steering system of the steering shaft power assist type composed of the planetary gear reduction mechanism to detect the working current of the power assist motor. The torque sensor is located...

The invention provides an automobile active suspension and electric power steering system integrated control device and a working method. The device comprises a data acquisition module, an A / D conversion module, an electronic control unit and an actuator. The actuator comprises a stepping motor and a booster motor. The data acquisition module is sequentially connected with the A / D conversion module and the electronic control unit, and the electronic control unit is then communicatively connected to the stepping motor and the booster motor. An electric power steering system is combined with anactive suspension system for integrated control, so that the mutual interference between the two systems can be better solved. At the same time, the system configuration is streamlined, information sharing is achieved between the systems, and limited sensor and controller resources are fully utilized to improve system reliability and reduce system cost.
Description
technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to an integrated control device and working method of an automobile active suspension and an electric power steering system. Background technique [0002] As a complex whole, the automobile has certain mutual influence and mutual restriction among the various subsystems during its driving process, and each control subsystem is generally only designed to improve a certain performance index of the vehicle, so the overall performance of the vehicle Depends on the coordination between the various subsystems. On the other hand, the application of electronic products in automobiles has gradually increased, and the layout of electronic circuits has also begun to appear, because the complexity of the circuits will not only increase the manufacturing cost, but also increase the weight of the vehicle. [0003] Based on the above two reasons, in order to obtain better o...
