Abstract

The application provides a simulation device suitable for automatic driving steering function acceptance, which comprises a fixing frame, a steering mechanism, a limiting device and a resistance mechanism, the steering mechanism is fixedly connected with the fixing frame in a manner capable of rotating along a first axis relative to the fixing frame; the limiting device comprises a stroke component capable of moving axially along the first axis direction under the driving of the steering mechanism and a stop mechanism for limiting the axial movement stroke of the stroke component; the resistance mechanism comprises an elastic body connected between the stroke component and the fixing frame, and the elastic body can provide a spring pressure parallel to the first axis direction. The mechanical limiting device and the angle sensor cooperate to simulate the functions of small-angle lightness, large-angle stability, rack end limiting and smooth damping feeling, etc., so as to provide a smooth steering feeling for the driver, and the driver has an intuitive feeling for the steering angle, and the cost is low.
