摘要： The left rear wheel is driven with the left motor and the right rear wheel is driven with the right motor. Selection of a control mode is made from a first control mode in which the left and right motors are driven in common and a second control mode in which the left and right motors are driven discretely and separately. A region in which the motors are driven is so arranged as to be altered in accordance with the running state of the vehicle, such as the lateral acceleration acting upon the vehicle body, the road surface friction coefficient .mu., the vehicle speed, the steered angle of the steering wheel, etc. A clutch can be disposed to couple the left and right wheels to be driven with the motors when a predetermined condition is met. When the motor is of a hydraulic type, the accumulator for accumulating the hydraulic pressure is disposed to thereby drive the secondarily driven wheels by the motors by taking advantage of the hydraulic pressure from the accumulator, in addition to the driving of the engine, leading to an increase in acceleration with a force larger than the force generated by the engine.
摘要翻译：左后轮由左电机驱动，右后轮由右电机驱动。控制模式的选择是从其中左右电动机共同驱动的第一控制模式和左右电动机分别驱动的第二控制模式进行的。电动机被驱动的区域被布置成根据车辆的行驶状态来改变，例如作用在车体上的横向加速度，路面摩擦系数μ，车速，转向角度方向盘等。当满足预定条件时，可以设置离合器以将马达驱动的左右车轮联接。当电动机是液压式时，用于积蓄液压的蓄能器被设置成除了驱动发动机之外还利用来自蓄能器的液压的压力来驱动二次驱动的车轮，从而导致以大于发动机产生的力的力增加加速度。

摘要： A system for steering a rear wheel of a vehicle having a mechanism for altering a steering ratio, .THETA.S, based on an amount of steering of the rear wheel to an amount of steering a front wheel. The system is disposed in an interconnecting mechanism for mechanically interconnecting the mechanism for steering the front wheel with the mechanism for steering the rear wheel. The value of .THETA.S is set by the following formula:.THETA.S=C1+B.multidot.C3.multidot..vertline.Y.vertline.-C4.multidot..vertline.dY.vertline.where .THETA.S is a steering ratio;Y is a yaw rate of a vehicle body;dY is a yaw acceleration of the yaw rate;C1 is a basic steering characteristic term;C3 is a yaw rate control gain;C4 is a yaw acceleration control gain; andB is a correction coefficient control gain term.The value of B increases when the amount of steering of the front wheel is small and decreases when the amount of steering of the front wheel is large.
