Abstract:
1. A steer-by-wire system comprising: a steering handle disconnected mechanically from a pair of steerable wheels; a steering motor for steering the steerable wheels in dependence on the manipulation of the steering handle; a reaction force motor for generating a steering reaction force against the manipulation of the steering handle; road reaction force detection means for detecting a road reaction force acting on the steerable wheels; first made-up value determination means for determining a first steering reaction force made-up value (Hc steering position detection means for detecting the steering position of the steering handle or the steerable wheels away from a neutral position; second made-up value determination means for determining a second steering reaction force made-up value (Hc command value generation means for determining first and second gains (G  using the first and second gains (G
