摘要
本文研究了采用一个附加的驱动力矩作用于一带 ABS系统的控制机构来缩短制动距离的可能性。在该 ABS的控制周期内 ,只有减小制动压力才能使锁止轮再加速 ,当在制动压力比较低的阶段可采用一外加牵引力矩来缩短加速时间。可用车辆发动机或一个附加电机作为一外加牵引力矩源。可以用一个数字模型来研究该系统缩短制动距离的可能性。采用一个仿真模型来分析该附加加速力的影响 ,并获得可缩短制动距离达到 1 0 %的结论。
The possibility of shortening the braking distance by the application of an additional driving torque to a control mechanism working with an ABS system is investigated in this work. In the ABS control cycle, the reacceleration of the locking wheels is provided only by decreasing the braking pressure. An external tractive torque can be used to shorten the time for acceleration during the phase of lowering of the braking pressure. The engine of the vehicle or an additional electric motor could be used as a source of external tractive force. The possibility of decreasing the braking distance by such a system is investigated by using a mathematical model. The effect of the additional accelerating torques is analysed with a simulation model and it is concluded that an increase of up to 10 per cent in braking distance may be obtained.
