20100023217 | Rear wheel steering angle controlling device for vehicles - The present invention provides a rear wheel steering angle controlling device for vehicles comprising: a rear wheel steering mechanism ( | 01-28-2010 |
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 |
20110029202 | VEHICLE MOTION STABILITY CONTROL SYSTEM - Provided is a vehicle motion stability control system that combines the VSA and RTC devices in a favorable manner, and is able to effectively control the behavior of the vehicle over an entire operating range including an extreme operating region and a normal operating region. An output of the RTC is transformed by a certain transfer function, and the front wheel steering angle δ | 02-03-2011 |
20110035113 | VEHICLE TOE ANGLE CONTROLLER - It is possible to drive a motor ( | 02-10-2011 |
20110046851 | REAR WHEEL STEERING VEHICLE - In a rear wheel steering vehicle equipped with a vehicle motion stability control system that can be selectively switched on and off, the motion stability of the vehicle is prevented from being impaired when an abnormal condition should develop to a rear wheel steering device of the vehicle. In addition to the rear wheel steering device, the vehicle is provided with an abnormal condition processing unit that turns on the vehicle motion stability control system upon detection of the abnormal condition of the rear wheel rear wheel steering device while the vehicle motion stability control system is turned off. | 02-24-2011 |
20110307142 | VEHICLE MOTION CONTROL SYSTEM - Provided is a vehicle motion control system that comprises a plurality of vehicle behavior control units that are controlled in a mutually coordinated manner, and is configured to operate as designed even when one of the vehicle motion control units should fail. If a RTC-ECU ( | 12-15-2011 |
20110313624 | REAR WHEEL TOE ANGLE CONTROL SYSTEM - Provided is a rear wheel toe angle control system that can prevent the impairment of the tracking performance of the electric actuator and enable the rear wheel toe angle control system to ensure the stability of the vehicle even when the electric actuator for steering the rear wheel according to the operating condition of the vehicle is subjected to an axial force. An ECU ( | 12-22-2011 |
20120041649 | REAR WHEEL TOE ANGLE CONTROL SYSTEM - An electric actuator (electric motor) is thermally protected without causing any unfamiliar impression in steering a vehicle. A temperature compensation gain computing unit ( | 02-16-2012 |

20080196966 | STEERING SYSTEM - A steering controller for an electric power steering device | 08-21-2008 |
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 |
20090177348 | VEHICLE WITH A VARIABLE REAR TOE ANGLE - In a vehicle provided with a rear wheel toe angle varying device for individually varying toe angles of rear wheels, upon detection of a failure to steer one of the rear wheels, the rear wheel of a healthy side is steered in a direction to enable the vehicle to travel straight ahead. Preferably, a control unit of the rear wheel toe angle varying device steers the rear wheel of a healthy side in parallel to the rear wheel of the faulty side, and the vehicle is enabled to travel straight ahead even though the traveling direction of the vehicle is at a certain angle with respect to the longitudinal line of the vehicle body. At this time, front wheels are typically steered at the same angle as the rear wheels. The device may further comprise a toe angle estimating unit. | 07-09-2009 |
