摘要： A rear wheel steering control system is provided. This system includes a traction control system which is responsive to generation of a difference in rotational speeds between front and rear wheels to recover traction of driven wheels and a compensating system which corrects a rear wheel steering angle, determined in a preselected relation to vehicle speed and a steered angle of the front wheels, based on the difference in rotational speeds between the front and rear wheels to provide a proper rear wheel target steering angle. The system restricts operation of the compensating system during operation of a traction control system to prevent a hunting frequency thereof from affecting the operation of the compensating system.

摘要： A system for controlling a steering angle for the rear wheels of a vehicle is provided. This system includes generally a rotational speed sensor for detecting rotational speeds of front and rear wheels to provide a difference in rotational speeds between the front and the rear wheels, an angle sensor for sensing a steered angle of a steering wheel, a steering controller for determining a rear wheel target steering angle, and an actuator for steering the rear wheels by the rear wheel target steering angle. The steering controller calculates a component of a difference in rotational speeds between the front and rear wheels caused by a difference in turning tracks therebetween and compensates for this component by the difference derived by the rotational speed sensor to provide a correction value for the rotational speeds between the front and rear wheels caused by acceleration during turning as a correction for a rear wheel steering angle. The steering controller determines the rear wheel target steering angle based on the correction.

摘要： Steering angle for rear wheels of a vehicle is controlled by determining a rear wheel steering angle in a preselected relation to a steered angle of a steering wheel. A correction factor for the rear wheel steering angle is based on a difference in rotational speed between front and rear wheels induced during turning. The correction factor for rear wheel steering angle is maintained at the value it had prior to braking to cancel the effect of braking slips on the determination of the rear wheel steering angle to improve steering stability.

摘要： To enable a smooth transition from motor travel to hybrid travel despite the situation-of-charge of a battery and reduce shock at the time of engagement of a clutch element.A hybrid system uses a state map 70 for deciding target torques of an engine and a motor on the basis of an accelerator stroke position, a vehicle velocity and a battery state-of-charge SOC. In the map 70, there are defined a motor maximum torque line that demarcates a motor upper limit torque that changes depending on the SOC and a motor margin torque line that is a predetermined margin lower than the motor maximum torque line. When the position on the map determined by the accelerator stroke position, the vehicle velocity and the battery state-of-charge is below the margin torque line, the hybrid system performs electric travel, and when the position on the map is on or above the margin torque line, the hybrid system initiates engine startup processing, and when the position on the map becomes a torque position exceeding the maximum torque line, the hybrid system sets target torques of the engine and the motor in order to achieve a torque corresponding to the accelerator stroke position.

摘要： A differential limiting torque control system for a vehicle includes a differential limiting clutch provided in a differential, a sensing section including sensors such as an accelerator position sensor, and sensors for sensing speeds of left and right front wheels and left and right rear wheels, and a control unit controlling a differential limiting torque of the differential limiting clutch in accordance with an accelerator opening degree of movement, a left and right drive wheel speed difference, and a drive wheel slip which is represented, for example, by a front and rear wheel speed difference, in such a manner that the differential limiting torque is held equal to a difference obtained by subtraction whose subtrahend is a quantity proportional to the drive wheel slip, and whose minuend is a sum of a quantity proportional to the accelerator opening degree and a quantity proportional to the left and right drive wheel speed difference. The control unit may further control the differential limiting torque in accordance with a lateral acceleration in such a manner that the subtrahend is decreased with increase of the lateral acceleration.

摘要： A hybrid vehicle includes an internal-combustion engine, an engine starter ISG motor, a main motor that drives rear wheels, a CVT pulley belt disposed between an engine output shaft and a front wheel shaft, a clutch connected between the output shaft of the internal-combustion engine and an input shaft of the CVT, a battery, and a hybrid controller. When the hybrid controller determines that there is a need to add a traction force of the engine from a state where the vehicle is driven by the main motor alone, the hybrid controller controls the respective components so as to start the engine by the ISG motor in a state where the clutch is disengaged, control a speed ratio of the CVT so that a CVT input speed achieves a target speed for starting clutch engagement, detects the engine rotation speed, detects the CVT input speed, and engages the clutch when a difference between those speeds falls within a predetermined range.
