PROBLEM TO BE SOLVED: To provide a steering reaction control device capable of stabilizing action of a vehicle by properly controlling steering reaction without generating feeling of disorder due to response delay. SOLUTION: To steering reaction Tfy+Tsat caused by front wheel lateral force and self-aligning torque, steering additive torque Ta of such characteristics as to quickly increase as a front wheel slip angleβf is increased is added to determine a steering torque Ts. Quick decrease of the steering reaction (steering torque Ts) in a range around a turning limit where the front wheel slip angleβf is large is thus prevented. Excessive steering by a driver is restricted, and return of a steering wheel by a driver is positively promoted. |
