摘要： PROBLEM TO BE SOLVED: To provide a vehicular steering control device capable of avoiding any excessive steering response at a very low speed while ensuring the steering feeling.
SOLUTION: The vehicular steering control device comprises a transmission ratio variable means which varies the transmission ratio of the steering amount of a steering wheel to the turning amount of a turning wheel, and varies the response of the turning amount to the steering amount to the quick side or the slow side, and a control means which computes the target transmission ratio based on the vehicle speed, and outputs the transmission ratio command value to the transmission ratio variable means based on the target transmission ratio. The control means executes the transmission ratio limiting control of limiting the transfer of the transmission ratio command value to the quick side when the target transmission ratio is changed to the quick side during the acceleration of a vehicle.

摘要： PROBLEM TO BE SOLVED: To provide a steering control device for a vehicle having a good response and steering rigidity. SOLUTION: When the steering control device adds and subtracts the rotation angle with respect to the steering angle of a steering wheel and outputs the command value so as to be a desired transmission ratio for the transmission ratio variable actuator capable of changing the transmission ratio expressing the relationship between a turning wheel and a steered angle, the steering control device corrects the command value based on the relationship between the direction of the operating force and the rotating direction of the transmission ratio variable actuator, and allows the actual transmission ratio to follow the command value before correction.
