Abstract: PROBLEM TO BE SOLVED: To improve a steering feel of a driver who is countersteering.SOLUTION: A vehicle steering device mounted on a vehicle is configured such that a target steering reaction force to be provided to a steering wheel is set on the basis of a steering angle and a vehicle speed, and that reaction force control is performed which provides the target steering reaction force. When the vehicle is in a countersteering state, a correction unit for correcting the target reaction force is included. The correction unit corrects the target steering reaction force by changing a referential steering angle MA1 in which the target steering reaction force S becomes a reference value (e.g., zero), so that the steering angle MA1 matches a vehicle body slip angle θs specified by a specifying unit in a target steering reaction force map for defining the target steering reaction force according to the steering angle.

Abstract: PROBLEM TO BE SOLVED: To provide a steering control device capable of appropriately controlling the response of an actual steered angle to a steering angle.
SOLUTION: The steering control device controls to add an assisting torque based on a steering operation by a driver. Specifically, the steering control device sets to a predetermined frequency response a transfer function in a range from the inputted steering angle to the actual steered angle. Then, based on the frequency response, the transfer function of the steering angle in a relational expression between the steering angle, the actual steered angle, and the assisting torque, and the transfer function of the assisting torque in the relational expression, the steering control device determines the assisting torque with respect to the steering amount. By performing the steering assist based on the determined assisting torque, it is possible to accurately control the response of the actual steered angle to the steering angle.

Abstract: PROBLEM TO BE SOLVED: To detect whether or not tire information is transmitted from an uninstalled tire when the tire information is transmitted from a plurality of tires including an installed tire attached to a vehicle and the uninstalled tire loaded on the vehicle without being attached to the vehicle and to perform no output to a vehicle control device when it is transmitted from the uninstalled tire. SOLUTION: When the received tire information is the one transmitted from the installed tire, air pressure information included in the tire information is outputted to the vehicle control device, however, when it is detected that the information is the one transmitted from the uninstalled tire, it is not outputted. Therefore, the vehicle control cannot be performed based on the air pressure of the uninstalled tire. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a steering vibration reduction device capable of appropriately reducing steering vibration while an engine is idling in accordance with a tilt-telescope position of the steering.
SOLUTION: In the steering vibration reduction device, when the tilt-telescope position of the steering is changed to a position B, while the engine is idling during free running of a vehicle, a target vibration number ftg/B corresponding to a target vibration level Ltg of the steering at the position B is calculated and a vibration level of the steering is significantly reduced to the target vibration level Ltg as an idling speed of the engine is changed to a target idling speed Nitg/B corresponding to the target vibration number ftg/B. When the vehicle stops, the tilt-telescopic position of the steering is changed to a position A where a vibration level corresponding to a basic setting value Nis of the idle speed becomes lower than that at the position B and the vibration level of the steering is significantly reduced to a level lower than the target vibration level Ltg.
