<p><P>PROBLEM TO BE SOLVED: To reduce incongruity of driving feeling when performing rear wheel steering while enhancing driving performance by the rear wheel steering. <P>SOLUTION: A rear wheel toe angle steering torque value setting part 32 includes a yaw rate standard value setting part for setting a yaw rate standard value, a lateral acceleration standard value setting part for setting a lateral acceleration standard value and a roll rate standard value setting part for setting a roll rate standard value based on a steering torque T and a rear wheel toe angle yaw rate value setting part for setting a rear wheel toe angle raw rate value, a rear wheel toe angle yaw rate value setting part for setting a rear wheel lateral acceleration value and a rear wheel toe angle roll rate value setting part for setting a rear wheel toe angle roll rate value respectively. A target rear wheel toe angle setting part 33 sets a target rear wheel toe angle in consideration of the rear wheel toe angle roll rate value. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
