PROBLEM TO BE SOLVED: To accomplish a steering reaction force control mechanism capable of suitably setting steering reaction force according to a driver and to contribute to reduction of a burden of steering or accurate steering angle control. SOLUTION: A mechanical impedance of the driver is presumed based on an operation amount of steering operation of the driver performed in a predetermined period or when a steering wheel is forcedly turned by a predetermined amount, and the steering reaction force of the steering wheel is set based on the mechanical impedance. Thereafter, the steering reaction force is changed based on the driving state of the vehicle. COPYRIGHT: (C)2007,JPO&INPIT |
