    • PURPOSE: A control method of driving force in the turning of an FR(Front-engine Rear-wheel drive) vehicle is provided to prevent an accident caused by overspeed the turning of an FR vehicle by controlling driving force through comparison between a steering angle and vehicle speed in turning of the vehicle. CONSTITUTION: A steering angle of a steering wheel is detected from a corresponding sensor. The RPM(Revolutions Per Minute,Rf,Rr) of front and rear wheels is detected from each RPM sensor. Then, a slip rate(S) and velocity(V) of the rear wheels are calculated from the RPM of the front and rear wheels. If the slip rate is lower than 0, the RPM of the rear wheels is lower than the RPM of the front wheels. Turning of a vehicle is decided by the steering angle. When the vehicle is turned, the velocity of the rear wheels is compared with Vm wherein the Vm is value obtained from a map of an ECU(Electronic Control Unit). The Vm is the optimum velocity for securing safety in turning of a vehicle at the current steering angle. If the velocity is larger than the Vm, the vehicle has danger of escaping a traffic lane. The ECU isolates fuel to a fuel injector to reduce the drive force of the rear wheels. Therefore, the turning velocity of the vehicle is reduced.
    • 目的:提供FR(前置发动机后轮驱动)车辆的转动中的驱动力的控制方法,以通过控制驱动力来防止由于车辆的转向而引起的超车而引起的事故 车辆转向车速。 构成:从相应的传感器检测方向盘的转向角。 从每个RPM传感器检测前轮和后轮的RPM(每分钟转数,Rf,Rr)。 然后,根据前轮和后轮的RPM计算后轮的滑差率(S)和速度(V)。 如果滑差率低于0,则后轮的转速低于前轮的转速。 车辆的转弯由转向角决定。 当车辆转动时,将后轮的速度与Vm进行比较,其中Vm是从ECU(电子控制单元)的映射获得的值。 Vm是用于在当前转向角度下确保车辆转弯时的安全性的最佳速度。 如果速度大于Vm,则车辆有逃离行车道的危险。 ECU将燃料隔离到燃料喷射器以减小后轮的驱动力。 因此,车辆的转向速度降低。
