20100332083 | STEERING SYSTEM FOR REAR WHEELS OF VEHICLE - A steering system for rear wheels of a vehicle without a dead zone in the vicinity of the steering wheel zero. The steering system includes a steering controller and control units that control the rear wheels to be steered in accordance with the steering angle of the steering wheel. The steering system performs a reduction control to provide a smaller steering control amount for the rear wheels in a range where a steering angle becomes smaller than a predetermined value, compared to a steering control amount for the rear wheels in the other ranges of the steering angle. When an angle speed of the steering angle becomes greater than a predetermined value, the steering system performs no reduction control or the reduction control with less reduced steering control amount for the rear wheels even in the range where the steering angle becomes smaller than the predetermined value. | 12-30-2010 |

20080203690 | ALIGNMENT CHANGING CONTROL DEVICE - An alignment changing control device that includes: a motor drive section which adjusts electrical power supplied to a motor of the electric actuator according to an operation command and, when receiving an operation inhibiting signal, limits or stops supplying the electrical power to the motor; a motor temperature estimating section for calculating an estimated temperature of the motor from at least a current supplied to the motor, an outside air temperature and a vehicle speed, based on heat balance relationship; and a comparators which transmits the operation inhibiting signal to the motor drive section when the estimated temperature of the motor calculated by the motor temperature estimating section is higher than a predetermined temperature, which is equal to or lower than an operation allowable temperature of the motor. | 08-28-2008 |
20090140502 | STEERING SYSTEM - The present invention improves response characteristics in turning traveling of a vehicle while traveling stability at the time of turning is kept. The present invention provides a system in which toe angles of left and right rear wheels are controlled based on a steering angular velocity, not a steering angle of a steering. In a steering system in which toe angles of left and right rear wheels are controlled independently, a steering angular velocity is calculated from a steering angle, and toe angle changers are controlled to tilt the toe angle of the right rear wheel to the left when the steering angular velocity is on the left side, and is controlled to tilt the toe angle of the left rear wheel to the left when the steering angular velocity is on the right side. | 06-04-2009 |
