<p>PURPOSE:To improve linear stability by generating a motor signal corresponding to deviation between a target steering torque signal and a manual steering torque detection value when a vehicle in given with lateral wind during its linear driving, and then driving a motor to resuming a vehicle to a position in the linear direction. CONSTITUTION:To a control box 1 a lateral acceleration detection sensor 2, a yawing angle detection sensor 3 and a steering torque detection sensor 4 are connected. Signals S1, S2 from the respective sensors 2 to 4 are input to data tables DT1, DT2, and respective target steering torque values TG, Tpsi obtained thereat are input to an adder 5. Next, the added values TG and Tpsi and a signal S3 from the sensor 4 are input to a reduction unit 6 and deviation DELTAT between the two is obtained and input to a data table DT3. Then corresponding to increase/decrease of the deviation DELTAT a target motor drive current signal IT is obtained, and according to the current signal IT and the drive current detection value detected by a current detection sensor 14, a motor 13 is drive controlled so that a stable linearity is obtained.</p> |
