    摘要： A foot controlled engine start and stop system characterized by a control circuit arranged among an ignition switch, an ignition grounding circuit, a warm-up switch, a starter motor, an accelerator pedal, an alternator and an actuator to disengage the parking brake when the engine is started. The system controls automatic start and stop of the starter motor and engine by feeding back the output frequency of the alternator. When installed on an off-road utility vehicle, this system, will allow the operator to conveniently start and stop the engine by depressing or releasing the accelerator pedal. The system senses the engine speed by monitoring the frequency of the alternator output voltage and disables the starter circuit when the engine speed is at or above a level necessary to allow the engine to run without starter assistance. When the operator removes his/her foot from the accelerator pedal, the ignition circuit is grounded to stop the engine. A warm-up switch is incorporated to disable the grounding switch when the operator wishes to allow the engine to continue to run while not present.

    摘要翻译： 一种脚踏控制的发动机起动和停止系统，其特征在于，在点火开关，点火接地电路，预热开关，起动电动机，加速器踏板，交流发电机和致动器之间布置有控制电路，以在停车制动器 发动机启动。 系统通过反馈交流发电机的输出频率来控制起动电机和发动机的自动启动和停止。 当安装在越野多功能车上时，该系统将允许操作员通过按下或释放加速踏板来方便地起动和停止发动机。 该系统通过监测交流发电机输出电压的频率来检测发动机转速，并且当发动机转速等于或高于允许发动机在没有起动器辅助下运行所需的水平时禁用起动器电路。 当操作者将他/她的脚从加速器踏板上移开时，点火电路接地以停止发动机。 当操作者希望允许发动机在不存在的情况下继续运行时，结合了预热开关来禁用接地开关。

    摘要： A method is provided for automatically determining a hitch raise rate calibration value for a hitch control system having a hydraulic actuator for moving the hitch, a valve for controlling flow of hydraulic fluid to the actuator and an electronic hitch control unit. The method includes applying a first control signal to the valve to cause the hitch to raise, determining a first hitch velocity as the hitch moves in response to the first control signal, and repeating these steps for a second control signal. The raise rate calibration value is then calculated as a function of a desired raise velocity, the first and second control signals and the first and second velocities.

    摘要： A towed scraper control system automatically lowers the scraper blade to a working position at the start of a scraping operation according to a certain method. The method includes sensing a ground speed of the vehicle and sensing a draft force applied by the scraper to the vehicle. With the vehicle pulling the scraper at or near a target ground speed over terrain with the blade positioned above a surface of the ground, the blade is automatically lowered with respect to the scraper frame at a first rate until the blade begins to engage the surface of the ground. Thereafter, while the vehicle continues to move forward at or near the target ground speed, the blade is lowered with respect to the frame at a second rate and for a duration related to the sensed ground speed so that lowering of the blade stops when the scraper wheel begins to enter a cut produced by the blade. With the blade fixed with respect to the scraper frame, the scraper is moved forward at the target ground speed for a distance determined as a function of the sensed draft force. Thereafter, the blade is raised with respect to the frame at a rate which matches a lowering rate of the wheels as they descend along the cut, and the blade is raised at this matching rate until the position of the blade matches the position of the blade after the first lowering step. Preferably, the second rate is slower than the first rate.
