摘要： Disclosed herein are stability display apparatus and methods. One apparatus comprises a driving state detection unit configured to detect a driving state of a vehicle in operation; a controller comprising an instability estimation unit configured to estimate an instability index indicating driving instability of the vehicle based on the driving state of the vehicle detected by the driving state detection unit and configured to determine changes in the instability index; and a display unit configured to display the instability index estimated by the instability estimation unit in a display region within a range less than or equal to an upper limit that is a limit of display and configured to display in the display region a representation of the changes of the instability index when the instability index is beyond the upper limit.

摘要： A vehicle steering control system is provided with a steering angle ratio varying mechanism, a variable power assisted steering mechanism and a steering angle ratio controller. The steering angle ratio varying mechanism varies the steering angle ratio, which is the ratio of the turning angle of the front wheels with respect to the steering angle of the steering wheel. The variable power assisted steering mechanism outputs an auxiliary steering force that supplements the steering force of the driver to the steering mechanism for turning the front wheels. The steering angle ratio controller increases the steering angle ratio in a steering angle range in the vicinity of the steering angle center point, and reduces the steering angle ratio in the steering angle range in the vicinity of the rack stopper position, regardless of the steering angular speed of the steering wheel.

摘要： An apparatus controls the steering angle of a pair of front or rear wheels and the braking forces to be applied to left and right wheels of at least one of the wheel pairs. The apparatus includes a control unit for calculating a target value for a dynamic parameter related to a motion of the vehicle based upon sensed vehicle operating conditions. The control unit calculates a target value for the steering angle of the one wheel pair and controls the steering angle to the calculated target value so as to bring the dynamic parameter to its target dynamic parameter value. An absolute value of the target or actual steering angle is calculated for comparison with a predetermined value. The control unit controls the second control unit to provide a difference between the braking forces applied to the left and right wheels of the one wheel pair so as to bring the dynamic parameter to the target dynamic parameter value only when the calculated absolute value exceeds the predetermined value.
