    • PROBLEM TO BE SOLVED: To provide a driving force distribution control system with a good steering feeling that not only securely detects disconnection but also prevents torque shock or sound from being generated when checking the disconnection.SOLUTION: A microcomputer 30 makes test current flow for use to detect the disconnection failure of an inductive load circuit. It is counted that the disconnection failure has occurred in the inductive load circuit if a difference between the value of the test current and that of the current flowing in the inductive load circuit is greater than the current difference threshold value. Further, the disconnection failure is determined to stop the system operation if the count number counted as if the disconnection failure has occurred in the inductive load circuit exceeds a predetermined frequency when the test current flowing frequency reaches the predetermined one.
    • 要解决的问题:提供一种具有良好转向感的驱动力分配控制系统,其不仅可靠地检测到断开,而且还防止在检查断开时产生扭矩冲击或声音。 解决方案:微型计算机30使测试电流用于检测感性负载电路的断开故障。 如果测试电流的值与在电感负载电路中流动的电流之间的差异大于电流差值阈值,则计算出在感性负载电路中发生断线故障。 此外,当测试电流流动频率达到预定值时,如果在感性负载电路中发生的断开故障计数的计数数量超过预定频率,则确定断开故障以停止系统操作。 版权所有(C)2012,JPO&INPIT
