摘要： A system for controlling a steering angle for the rear wheels of a vehicle is provided. This system includes generally, a torque sensor for detect torque of driven wheel, an angle sensor for sensing a steered angle of front wheels, 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 first determines a rear wheel steering angle based on the steered angle of the front wheels and then calculates a correction for the rear wheel steering angle according to variation in the torque of the driven wheels during running to determine the proper rear wheel target steering angle.

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： 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.

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： 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.

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.

摘要： A charging and discharging control device for a secondary battery includes a secondary battery, a controller, a charging unit for charging the battery, a ON/OFF switch between the battery and the charging unit and a control switch for controlling the discharge current. At charging the battery, the ON/OFF switch is turned on and a voltage Ve of the secondary battery is compared with a charge stop voltage Vmax by the controller. If Ve.gtoreq.Vmax, the charging operation is ended. At discharging, the control is turned on and the voltage Ve is compared with a discharge stop voltage Vmin. If Ve.ltoreq.Vmin, the discharging operation is ended. Corresponding to charging/discharging history of the battery, the controller corrects the voltage Vmin so as to be increased and the voltage Vmax so as to be decreased, whereby the life span of the secondary battery can be extended.
