PURPOSE:To provide a rear wheel steering control device providing rear wheel steering giving no feeling of physical disorder to a diver. CONSTITUTION:This device is provided with sensors such as a steering wheel angle sensor 16, vehicle speed sensor 18, forward and rearward acceleration sensor 20, lateral acceleration sensor 22 and a yaw angle speed sensor 24, a 4WS controller 25 for computing a target rear wheel steering angle based on detection signals, approximate computing block 26 computing an approximate value A of vehicle body center-of-gravity slip angle, a preprocessing block generating input information and memory 30, a neural network 32 inputting input information and approximate value and outputting control gain which is learnt based on the teaching gain selected by a function evaluation driver and is corresponding to the teaching gain C, compensation block 27 outputting a new target rear wheel steering angle deltar by multiplying together the control gain and a target rear wheel steering angle from a 4WS controller, and a rear wheel steering system 10. |
