    摘要: A control system for an electric vehicle comprises a motor speed detector and a sensor for detecting an accelerator angle and outputting a motor speed error command based on the difference between motor speed and a speed required by the present accelerator angle. A motor speed command is generated based on the error command and the detected motor speed. A feedback control portion outputs a torque command based on the motor speed command and the detected motor speed and the driving force of the motor is controlled based on the torque command.

    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: A method of and system for controlling a torque distribution over four wheels of four-wheel drive vehicle when the vehicle is making a turn. When an outer wheel revolution speed is higher than an inner wheel revolution speed, a differential action limiting force is decreased or weakened and a torque distribution ratio, viz., a ratio of a portion of torque distributed toward the front wheels (secondary driving wheels) to the remaining portion of torque distributed toward the rear wheels (primary driving wheels), is decreased. When the inner wheel revolution speed is higher than the outer wheel revolution speed, the differential acting limiting force is increased or strengthened and the torque distribution ratio is increased.

    摘要: To reduce a torque drop caused by shift shock and time lag in a hybrid system.In a hybrid system control method of the present invention, when the gear ratio of a transmission is upshifted, the torque of a motor is instantaneously increased when half clutch control of a clutch is started, and during half clutch control, the torque of the motor is controlled to be zero or minus to compensate for an increase in a vehicle drive torque resulting from rotational inertia of an engine. The torque of the motor is increased when the clutch is completely engaged and, after this increase of the torque, is attenuated by a predetermined time constant. When the gear ratio of the transmission is downshifted, the torque of the motor is increased when half clutch control of the clutch is started, and during half clutch control, the torque of the motor is attenuated by a predetermined time constant from the torque that was increased to compensate for a drop in the vehicle drive torque resulting from rotational inertia of the engine and is smoothly connected to a torque up amount at the time of complete engagement of the clutch.

    摘要: A travel condition detecting section detects travel conditions of an electric motor car. According to the detected travel conditions, a required output calculating section calculates a required travel output. According to the calculated required travel output, a control commanding section determines travel outputs to be allocated to a plurality of motors coupled to driven wheels of the electric motor car, respectively in such a way that the total power consumption of the motors can be minimized, and further outputs control commands to the motors on the basis of the determined travel outputs allocated to the respective motors.

    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.
