Embodiment Construction
[0052] Referring to FIG. 1 , there is schematically shown a steering control device according to an embodiment of the present invention, the steering control device is installed in a vehicle as shown in FIG. 2 , for example. That is, the apparatus is installed in a vehicle including: a steering wheel SW adapted to steer a pair of wheels WHfr and WHfl serving as right and left steering wheels; an engine EG serving as a power source for generating power and drive shafts DSfr and DSfl adapted to transmit power to wheels WHfr and WHfl, which also serve as right and left drive wheels. The device includes a steering torque control device, wherein the steering wheel torque (abbreviated as steering torque) Ts of the steering wheel SW is detected by the steering torque detection device M1 as shown in FIG. The assist torque target value determining means M2 of the target value of the steering assist torque calculates the target value of the torque used as the assist torque for assisting...

A steering control apparatus is provided for a vehicle having a steering wheel for steering its steered wheels, a power source for generating power, and drive shafts for transferring the power to the wheels, to be served as driving wheels of the vehicle, and a traction control device for controlling braking torque applied to the wheels. The apparatus comprises a detection device for detecting the braking torque applied to the wheels, a calculation device for calculating a driving force difference between the wheels, on the basis of the detected braking torque, a power source state detection device for detecting an actuating state of the power source, and a control device provided for controlling steering torque created by the steering wheel, and applying torque steer reducing torque to the steering wheel. A desired value of the torque steer reducing torque is determined, on the basis of the driving force difference and the actuating state of the power source. And, the torque steer reducing torque is applied to the steering wheel, in accordance with the desired value of the torque steer reducing torque, to reduce the torque steer.
Description
technical field [0001] The present invention relates to vehicle steering control apparatus, and in particular to steering control apparatus for alleviating torque steer induced on a vehicle steering wheel. Background technique [0002] In general, in a steering apparatus of a vehicle in which steered wheels are used as drive wheels, a phenomenon in which a steering force or a steering holding force changes in response to a change in driving force is called torque steer, which is desired to be suppressed. For example, Japanese Patent Laid-Open Publication No. 11-129927 corresponding to U.S. Patent No. 6,154,696 discloses a vehicle equipped with an electric power steering device and a vehicle for independently controlling (or distributing) tractive force and / or Torque distribution device for braking force to improve its handling and stability. In U.S. Patent No. 6,154,696 is disclosed a steering control system for controlling torque in a vehicle equipped with an electric stee...
