    • A method for gear selection during driving of a vehicle in a heavy uphill drive condition is provided, the vehicle including an engine, an automated mechanical transmission, a clutch, a control unit for receiving input signals including signals indicative of vehicle speed, engaged ratio of the transmission, rotational speed of the engine, rotational speed of a input shaft and displacement of a throttle control for engine torque request, and for processing the signals in accordance with programmed logic rules to issue command output signals to the engine, to the transmission and to said clutch. When sensing a heavy uphill drive condition a target gear is determined for the uphill drive condition, the target gear being the highest possible gear with lowest possible gear ratio where the vehicle, in view of at least current circumstances, will be at least theoretically able to hold a constant vehicle speed or accelerate at least slightly, and where further selection of downshifts will be adapted so that no lower gear than the target gear will be selected and engaged.
    • 提供了一种用于在重型上坡驾驶状态下驾驶车辆时进行档位选择的方法,所述车辆包括发动机,自动机械变速器,离合器,用于接收包括表示车速的信号的输入信号的控制单元, 发动机的转速,发动机的转速,输入轴的转速以及用于发动机扭矩请求的节气门控制的位移,以及根据编程逻辑规则处理信号以向发动机发出指令输出信号,以及 到离合器。 当检测到重的上坡驱动条件时,为上坡驱动条件确定目标档位,目标档是具有最低可能传动比的最高可能档位,鉴于至少目前的情况,车辆将至少在理论上能够 保持恒定的车速或至少稍微加速,并且进一步选择降挡将被适配,使得不会选择和啮合比目标档位更低的档位。
