<P>PROBLEM TO BE SOLVED: To contribute to stability of a vehicle behavior by notifying a driver that a toe angle control function of a rear wheel is put into a prescribed state. <P>SOLUTION: When a saturation state deciding part 81d compares a target toe angle α<SB>TR</SB>(α<SB>TL</SB>) input from a steering control ECU 130 with an actual toe angle α<SB>R</SB>(α<SB>L</SB>) of the present rear wheel 2R (2L) input from a stroke sensor 38 and the toe angles α<SB>TR</SB>(α<SB>TL</SB>) and the α<SB>R</SB>(α<SB>L</SB>) coincide with each other, the saturation state deciding part 81d decides that the toe angle control function of the rear wheel 2R (2L) is in a saturation state and outputs a decision signal to the steering control ECU 130. In the steering control ECU 130, a driving signal is output to an electric motor driving circuit 23 of an electric power steering device 110 since the decision signal is input from the saturation state deciding part 81d, and operation reaction of a steering wheel 3 is made heavier than a conventional steering wheel 3 by controlling the electric motor 4. <P>COPYRIGHT: (C)2010,JPO&INPIT |
