摘要： The invention relates to a method for facilitating hill-starting of a stationary motor vehicle, which method comprises the following steps: - at least one braking device is applied using a brake pedal, - a control unit (30) estimates the traveling resistance of the vehicle, - the control unit (30) determines a starting gear, a starting torque and a starting speed with regard to said estimated traveling resistance, - the driver releases a brake pedal, the brakes being kept applied for a certain time, - the driver operates an accelerator pedal to a position at least corresponding to said minimum transmitted torque, - a clutch device (2) for a gearbox (3) is activated by the control unit (30) when the starting speed has been achieved, - the control unit (30) releases the braking devices as a function of the increase in the transmitted, driving torque of the clutch. The invention also relates to a device for implementing the method.

摘要： A method for operating a semi-automatic or automatic mechanical transmission (310) of a heavy truck when driving at idle speed. The method includes supplying fuel to the engine (300) of the heavy truck at a rate that facilitates engine-idle operation. In another step, the method engages the automatic or semi-automatic transmission in a gear higher than the starting gear of the transmission and permits the truck to operate at a first substantially uniform driving velocity (S1) under engine-idle power. Depending upon traffic and environmental requirements which require a higher speed, the driver upshifts the semi-automatic or automatic transmission by depressing a control device (350) for manual gear selection arranged on a gear shift lever (340) of the truck and then drives the truck at a second substantially uniform driving velocity (S2) under engine-idle power. The second (S2) substantially uniform driving velocity is greater than the first (S1) substantially uniform driving velocity.

摘要： A drive unit for a motor vehicle, comprising a drive engine (1), a transmission (9) having an intermediate shaft (11) with intermediate shaft brake (17), and a friction clutch (3) which is engaged between the engine and the transmission and which, via an electronic control unit (12), is operated by an operating cylinder (15). A torque transmitter (19) is provided, which detects input torque to the transmission. The control unit (12) is arranged so as, on predetermined occasions, when the transmission is in the neutral position, the friction clutch is disconnected and the intermediate shaft brake is applied, gradually to engage the friction clutch and to register and store, as a function of the position the operating piston of the operating cylinder, the torque measured by the torque transmitter.

摘要： Automatic engaging method (and disengaging method and device) for a coupling-dependent power take-off (32) when the vehicle is in motion, which is driven by an engine (1), arranged in the vehicle, via an automated disk clutch (3), an automatic stage-geared gearbox (9) in which a shaft (11) for driving the power take-off (32) is arranged. A control unit (45) controls the gearbox (9), the disk clutch (3) and the engine (1). The method is characterized in that the control unit registers that engagement of the power take-off (32) is requested; the speed of the engine (1) is controlled so that the input shaft (7) of the gearbox becomes virtually torqueless; the disk clutch (3) is disengaged and the gearbox is put in neutral position so that the intermediate shaft (11) of the gearbox is disengaged from the driving wheels of the vehicle; the intermediate shaft (11) is braked; the power take-off (32) is engaged; the control unit (45) couples the disk clutch (3) together. A torque transmitter is arranged at the power take-off (32).

摘要： Drive unit for motor vehicles, comprising an internal combustion engine (1) and a non-synchronized auto-shift gearbox (9), which has an intermediate shaft 850) and is connected to the engine via an automated clutch (3). The clutch and the gearbox are controlled by an electronic control unit (45), to which there are fed signals representing the selected gear from a gear selector (46) and signals representing various engine and vehicle data. The control unit is disposed, when the gear selector is in the neutral position, the clutch is engaged and the vehicle speed is so low the synchronisation by means of the engine requires an engine rpm lower than the enging idle rpm, to first disengage the clutch, then brake the intermediate shaft to a standstill, thereafter engage the clutch slowly and finally engage the selected gear, when the input shaft has reached a suitable rpm range for engagement of the selected gear.
