    摘要: A method for cold start protection of a vehicle drivetrain is provided. If temperature is below a certain predetermined temperature limit, which is lower than normal working temperature of an engine, then maximum allowable engine torque and/or maximum allowable engine rate of rotation is/are limited to define a limited drivetrain working area adapted to cold start sensitivity of at least one of the engine, and the transmission. Transmission control is automatically adapted to prevailing limited engine working area.

    摘要: A method for a more efficient use of a vehicle combustion engine during driving, the vehicle including an automatic step geared transmission. The method includes the steps of sensing current engine rotational speed and engine rotational speed increase, estimating necessary minimum upshift engine rotational speed for a coming gear upshift, registering that the engine rotational speed stops increasing without reaching the minimum upshift engine rotational speed, and where the engine rotational speed stops increasing relatively close to a maximum engine rotational speed where engine efficiency is relatively low and, automatically controlling engine output torque in order to limit the engine rotational speed to a first predetermined engine speed where engine efficiency is relatively high.

    摘要: A method and device for modifying throttle control characteristics of a throttle control in a vehicle, the vehicle including an engine coupled to engine driven vehicle wheels via a stepped gear mechanical transmission, and where requested engine torque at a given engine speed of the engine is controlled as a function of positions of the throttle control. When sensing a gear shift to a vehicle high speed gear, a control unit modifies the characteristics so the engine torque and engine speed will be controlled via said throttle control along a first set of relatively flat curves, when the curves are plotted in a diagram with engine torque on the y-axis and engine speed on the x-axis. When sensing a gear shift to a vehicle low speed gear, the characteristics are modified so the engine torque and engine speed will be controlled via the throttle control along a second set of curves that are steeper than the first set of curves, so that when driving with a vehicle low speed and for a certain change in engine speed, a greater change in torque will be provided than when controlling is done in accordance with the first set of curves.

    摘要: 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.
