The invention provides a system and method for operating a vehicle in a low transmission range. Systems and methods for operating a driveline that includes a step ratio transmission or a continuouslyvariable transmission (CVT) that may be operated in a step ratio mode are disclosed. In one example, engagement speeds for transmission gears are adjusted as a function of vehicle mass, road grade, and requested braking torque.
本公开提供了“用于在低变速器范围内操作车辆的系统和方法”。公开了用于操作包括阶梯传动比变速器或可以以阶梯传动比模式操作的无级变速器(CVT)的传动系的系统和方法。在一个示例中,根据车辆质量、道路坡度和所需的制动扭矩来调节变速器挡位的接合转速。
