摘要： PROBLEM TO BE SOLVED: To provide a steering device for a vehicle, further improving responsiveness, and achieving better steering property. SOLUTION: An ECU 9 (microcomputer 21) in the steering device for a vehicle calculates a torque differential instruction angle θdt* as a compensation component based on a differential value of a steering torque τ input to steering. The torque differential instruction angle θdt* as a second compensation component is superimposed on a gear ratio variable instruction angle θgr* as a basic component, together with a differential steering instruction angle θls* as a first compensation component.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle steering device, capable of restricting occurrence of overshooting due to delay in counter steering by a driver so as to quickly stabilize the vehicle. SOLUTION: An IFS control computation part 35 is provided with a counter steering determination part 77 as a means to determine whether or not there is counter steering by a driver under OS control. As the counter steering determination part 77 determines that there is counter steering during OS-controlled operation, in case where it is determined that the yaw moment of the vehicle is varied to be stabilized, then correction is carried out to reduce an OS-controlled ACT command value θos* computed by an OS control computation part 65.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle steering device, capable of stabilizing a vehicle posture quickly even on a low-μ road. SOLUTION: An IFS control computation part 35 is provided with a counter steering detection part 77 as a counter steering detection means for detecting counter steering by a driver during OS-control. A vehicle model computation part 61 is provided with a regular circle turning value computation part 78 to compute a target state quantity value in case where the vehicle is turning on a regular circle (the regular circle turning value RyO_cy, θspO_cy). To the vehicle model computation part 61, a counter signal S_cs outputted by the counter steering detection part 77 is inputted. The vehicle model computation part 61 substitutes previous values RyO_b and θspO_b for the target state quantity (target yaw rate RyO and target slip angle θspO) as bases for vehicle model computation by values representing the other way to the counter direction more than the previous values in a case where the counter signal S_cs indicates completion of counter steering.
