    • PURPOSE: A portable sliding resistance measuring device is provided to make an automatic measurement possible, to enhance the reliability of a measurement result, and to reduce power consumption. CONSTITUTION: A portable sliding resistance measuring device comprises a body(100), a driving unit(110), a load block(130), a push pull gauge(120), and a connection unit(140). An opening is formed in the body. The driving unit comprises a replaceable battery, a linear motor and a forward-backward switch. The load block comprises a block body, a plurality of bearings, and a rubber sensor. The block body is arranged in an opening area of the body. The bearing is arranged in the one side of the block body, thereby roll-contacting to the ground through the opening area. The rubber sensor is arranged in the other side of the block body and contacts to the ground, thereby being supported. The push pull gauge is mounted on the block body of the load block, thereby measuring a coefficient of static friction. The connection unit connects the driving unit and the load block.

    • Control means (10) for controlling operations of actuators (3A, 3B, 3C) of a vehicle (1) creates time series of future behavior of the vehicle (1) by using a vehicle model (41). Here, a state amount of the vehicle model (41) is initialized according tot he state amount of the actual vehicle (1) and the future behavior is created starting from the initial state amount. The future behavior is created by matching the operation instruction of the actuators in the vehicle model (41) at the current time with a basic value based on the operation of an operator (5) such as a steering wheel of the vehicle (1). It is judged whether evaluation objects such as the vehicle movement, the road surface reaction force, and wheel sliding in the created future behavior satisfy predetermined conditions. According to the evaluation results, operation instructions of the actuators (3A, 3B, 3C) are successively decided. Thus, it is possible to appropriately predict the future behavior of the vehicle and enable appropriate travel of the vehicle.
    • 用于控制车辆(1)的致动器(3A,3B,3C)的操作的控制装置(10)通过使用车辆模型(41)创建车辆(1)的未来行为的时间序列。 这里,根据实际车辆(1)的状态量来初始化车辆型号(41)的状态量,并且从初始状态量开始创建未来行为。 通过将当前时刻的车辆模型(41)中的致动器的操作指令与基于车辆(1)的方向盘的操作者(5)的操作的基本值相匹配来创建未来行为。 评估对象如车辆运动,路面反作用力以及在创建的未来行为中的车轮滑动是否满足预定条件。 根据评价结果,依次确定执行器(3A,3B,3C)的操作指令。 因此,可以适当地预测车辆的未来行为并使车辆适当行驶。
