    • PROBLEM TO BE SOLVED: To provide an all-wheel drive traction control system for a turf maintenance vehicle capable of preventing slip of tires. SOLUTION: The all-wheel drive traction control system 110 of the turf maintenance vehicle 10 includes a primary wheel for propelling the vehicle. A first motor rotates the primary wheels 34, 34'. The traction control system has a first portion for communicating with a first motor to monitor either a first motor 80 current demand or a rotational speed of the primary wheel or the first motor and generates a traction control value. A secondary wheel 28 rotated by a second motor 90 steers the vehicle in a vehicle non-slip condition. A second portion of the traction control system determines a steering angle value α of the secondary wheel. A speed threshold limit stored in the traction control system and compared to the traction control value generates a slippage occurrence message indicative of a primary wheel traction loss event. A second motor drive signal created by comparing the steering angle value and the slippage occurrence message energizes the second motor during the traction loss event. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供一种能够防止轮胎滑动的草坪维护车辆的全轮驱动牵引力控制系统。 解决方案:草皮维护车辆10的全轮驱动牵引力控制系统110包括用于推进车辆的主轮。 第一马达使主轮34,34'旋转。 牵引力控制系统具有第一部分,用于与第一电动机通信以监测第一电动机80的电流需求或主轮或第一电动机的转速,并产生牵引控制值。 由第二马达90旋转的副轮28以车辆防滑状态转向车辆。 牵引力控制系统的第二部分确定次级车轮的转向角度值α。 存储在牵引力控制系统中并与牵引力控制值相比较的速度阈值极限产生指示主轮牵引损失事件的滑动发生信息。 通过比较转向角值和滑动发生消息而产生的第二电动机驱动信号在牵引损耗事件期间激励第二电动机。 版权所有(C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a turf maintenance vehicle which is easy of operation control, a dynamic tactical steering feedback system therefor, and a method of controlling the turf maintenance vehicle.
      SOLUTION: The dynamic tactical feedback system for the turf maintenance vehicle includes an input device that detects a steering angle and/or a ground speed of the turf maintenance vehicle. The input device transmits an input signal correlative to the steering angle and/or ground speed of the turf maintenance vehicle. The system also includes an output device that affects a steering resistance, a turning ratio, a speed limit, the ground speed and/or a turning angle limit of the turf maintenance vehicle. The system additionally includes a controller that receives the input signal and outputs a control signal to the output device from the input signal so as to change the steering resistance, the turning ratio, the speed limit, the ground speed and/or the turning angle limit of the turf maintenance vehicle from the input signal. A method of controlling the turf maintenance vehicle is also disclosed.
