    • PROBLEM TO BE SOLVED: To provide an improved vehicle control system for solving problems in a conventional technology.SOLUTION: A vehicle speed computer 10 has a configuration to calculate vehicle speed as the latest wheel speed or mean speed of two or more wheels to decide a vehicle speed value, and a wheel slip amount is decided by comparing each wheel speed with the calculated vehicle speed. In a controller 14, a predetermined wheel slip threshold is stored, a wheel slip amount signal 16 as a second output signal is always compared with the wheel slip threshold, and it is determined whether or not the state requires torque relaxation for wheel slip relaxation. If the value of the wheel slip amount signal 16 exceeds the wheel slip threshold, the state is certified as a wheel slip state, and additional toque from a power train to the wheel is relaxed, and thus a wheel slip start or the occurrence of a wheel slip more than that is prevented.
    • 要解决的问题:提供一种用于解决常规技术中的问题的改进的车辆控制系统。 解决方案:车速计算机10具有计算车速作为两个或更多个车轮的最新车轮速度或平均速度来决定车速值的结构,并且通过将车轮滑动速度与 计算车速。 在控制器14中,存储预定的车轮滑移阈值,作为第二输出信号的车轮滑移量信号16始终与车轮滑动阈值进行比较,并且确定状态是否需要用于车轮滑行松弛的转矩松弛。 如果车轮滑移量信号16的值超过车轮滑移阈值,则状态被认证为车轮滑移状态,并且从动力传动系到车轮的附加转矩被放宽,因此车轮打滑开始或发生 车轮滑动多于预防。 版权所有(C)2012,JPO&INPIT
