4 An automotive steering system having intelligent 4 wheels steering function

摘要

The present invention relates to a steering apparatus of a vehicle having an intelligent four-wheel steering function, wherein the front and rear wheels of the vehicle are controlled together with the engine by using an electric motor independent of the engine, as well as when changing lanes while driving at a high speed. Steering the rear wheels of the vehicle in reverse phase to stabilize the behavior of the vehicle while steering the rear wheels in the same phase during parking or U-Turn of the vehicle to reduce the radius of rotation of the vehicle relatively.;The present invention for achieving the above object, the signal input unit 10 for measuring the steering angle and the vehicle speed of the steering wheel, the signal of the signal input unit 10 according to the built-in logic (Logic) and Program (Program) The main controller 20 and the front and rear wheel drive devices 30 and 40 which are controlled according to the control signal of the main controller 20, which are processed to generate a control signal, are controlled by the main controller 20. The front and rear wheel drive devices 30 and 40 respectively include motion controllers 31 and 41, power amplifiers 32 and 42 for amplifying the signals of the motion controllers 31 and 41, and the power amplifiers 32 and 42. Steering motors 33 and 43 operated at a predetermined rotation amount according to a signal transmitted through the connecting means, and connecting means for manipulating steering racks 36 and 46 for steering the front wheels according to the rotational force of the steering motors 33 and 43 ( 35, 45).
