摘要： In a vehicle steering apparatus having a variable gear ratio unit arranged midway along a steering transmission system for connecting a steering wheel and tires to change the transmission ratio, and an ECU for variably controlling the variable gear ratio unit in accordance with the state of a vehicle, the variable gear ratio unit includes a motor controlled by the ECU, and a reducing mechanism which has a transmission ratio for allowing to maintain the steering angle of the steering wheel with respect to an RF reverse input and transmits the rotation of the motor to the output side. Even if a reverse input acts from a tire side during traveling, the relationship between the steering amount of the steering wheel and the turning amount of the tire can be kept unchanged.

摘要： Provided is a steering control device (10) for a vehicle (12), including a front wheel steering device (14) and a rear wheel steering device (42). When a magnitude of a steering angle (MA) is large in a state in which rear wheels are steered by the rear wheel steering device in the same phase with respect to front wheels, the steering control device carries out calculation so as to increase a rear wheel target correction steering angle Δδbt for a correction steering for the rear wheels (18RL and 18RR) toward an opposite phase direction with respect to the front wheels (18FL and 18FR) compared with when the magnitude of the steering angle is small, and controls the rear wheel steering device based on the target correction steering angle Δδbt, thereby increasing a slip angle toward the inside of a turn of the vehicle.

摘要： A vehicle steering control device includes a turning angle varying device serving as a first turn response change device for changing a gain of yaw rate of a vehicle with respect to steering operation, and a rear wheel steering device serving as a second turn response change device for changing a gain of lateral acceleration of the vehicle with respect to the steering operation. Under a state in which magnitude of curvature of a travel path is equal to or less than a first reference value, at least one of the turning angle varying and rear wheel steering devices is controlled so that a ratio of the gain of the lateral acceleration to the gain of the yaw rate increases when a width of the travel path is small compared with when the width of the travel path is large.
