摘要： A system and method for operating an electric vehicle. In another exemplary embodiment, a system for operating an electric vehicle is disclosed. The system includes a first motor and a transmission coupled to the first motor. The transmission is configured to shift gears when a speed of the electric vehicle crosses a shift threshold. The shift threshold is independent of a position of an acceleration pedal of the electrical vehicle.

摘要： A method of controlling torque output of a power-plant during launch of a vehicle having a transmission with a manually-operated clutch is disclosed. The power-plant torque is varied based on clutch pedal and throttle pedal positions using a proportional-integral-derivative (PID) control logic in an electronic fuel control system. The method includes setting power-plant idle speed, detecting clutch engagement without application of the throttle pedal, and raising power-plant torque after clutch engagement is detected. In each PID feedback loop, the method includes detecting actual power-plant speed and a rate of change in actual power-plant speed, and adjusting the raised power-plant torque in response to the determined rate of change in actual power-plant speed. The method additionally includes determining a difference between the set idle speed and the actual power-plant speed, and maintaining constant power-plant torque, if the difference between the set idle and actual power-plant speeds is within an acceptable range.
摘要翻译： 公开了一种在具有手动离合器的变速器的车辆发射期间控制发电厂的扭矩输出的方法。 在电子燃料控制系统中，使用比例积分微分（PID）控制逻辑，电厂扭矩基于离合器踏板和油门踏板位置而变化。 该方法包括设置发电厂怠速，检测离合器接合而不施加油门踏板，并且在检测到离合器接合之后提高发电厂扭矩。 在每个PID反馈回路中，该方法包括检测实际发电厂速度和实际发电厂转速的变化率，并根据确定的实际发电厂转速变化率来调整升高的发电厂转矩。 该方法还包括确定设定怠速和实际发电厂速度之间的差异，并且如果设定的怠速和实际电厂速度之间的差在可接受的范围内，则保持恒定的发电厂转矩。
