    • PROBLEM TO BE SOLVED: To suitably support the driving operation of a driver by using an estimated road surface μ not only for controlling vehicle behavior but also for effectively informing the driver thereof.
      SOLUTION: S102 and S103 compute braking/driving force Fx and lateral force Fy, respectively. S104 selects a road surface μ estimation part (a first road surface μ estimation part 25 or a second road surface μ estimation part 26, or no determination) to be used for determination with reference to a map preset from the braking/driving force Fx and the lateral force Fy. S105 reads a display flag Fla from the road surface μ estimation part. In the case of a high μ road, a display 1 is shown (S107), in the case of a medium μ road, a display 2 is shown (S109), in the case of a low μ road, a display 3 is shown (S111), and in the case of another uncertain road surface μ, a display 0 is shown (S112), respectively.

    • 要解决的问题:通过使用估计路面μ来适当地支持驾驶员的驾驶操作,不仅用于控制车辆行为,而且有效地通知驾驶员。 解决方案:S102和S103分别计算制动/驱动力Fx和横向力Fy。 S104根据从制动/驱动力Fx预先设定的地图,选择要用于确定的路面μ估计部分(第一路面μ估计部25或第二路面μ估计部26,或不确定),以及 侧向力Fy。 S105从路面μ估计部读取显示标志Fla。 在高μ路的情况下,示出了显示1(S107),在中等μ路的情况下,示出了显示2(S109),在μ路低的情况下,显示3 (S111),在另一不确定路面μ的情况下,分别显示显示0(S112)。 版权所有(C)2005,JPO&NCIPI
