摘要： A combustion engine (1) for a motor vehicle, having electronic members (20, 23) with memory function for controlling the output torque of the engine at least in dependence on signals representing an injected quantity of fuel. Reference values of engine torque at different rev speeds are stored in the control members. A torque transmitter (24) detects and transmits to the control members a signal representing the current output torque. The control members compare the current torque with the stored reference value in order to determine whether the performance of the engine is normal.

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： Motor-driven cargo vehicle with an automated clutch ( 33 ) and gearbox ( 39 ) between the engine ( 31 ) and the vehicle drive wheels. The gearbox and the clutch are controlled by an electronic control unit ( 19 ) depending on a set position of a manual gear selector ( 53 ). The control unit is arranged, when starting off with the gear selector in the position for automatic shifting, to select the highest gear speed which makes starting off of the vehicle possible with the available torque at engine idle speed, introducing an amount of energy from the engine to the clutch which at most amounts to a predetermined maximum value.

摘要： Drive means for motor vehicles, comprising an internal combustion engine (1) and an unsynchronised autoshift gearbox (9). The clutch and the gearbox are s controlled by an electronic transmission control unit (45) which communicates with an engine control unit (48), to which are fed signals representing the selected gear from a gear selector (46) and signals representing various engine and vehicle data. The input shaft of the gearbox is coordinated with a torque sensor (60), which provides a signal dependent of the torque on the input shaft to to the transmission control unit, which is disposed to continuously register the current torque on the input shaft and utilize the torque signal from the torque sensor to calculate the current vehicle motion resistance. The gear selection is made here based on the calculated vehicle motion resistance.

摘要： The invention relates to an increment shifted transmission (9) for motor vehicles, comprising an in-going shaft in a housing, at least one intermediate shaft in the housing which exhibits at least one gear wheel 816, 17) in engagement with a gear wheel (12, 15) on the in-going shaft, a main shaft in the housing with gear wheels (15, 21, 22, 23) in engagement with gear wheels (18, 19, 20) on the intermediate shaft with at least one of the gear wheels in each neutrally engaging pair of gear wheels on the intermediate shaft and the main shaft being rotateably arranged about its shaft and by means of coupling organs (13, 24, 25) being lockable onto its shaft and manoeuvring organs (40, 41, 42) co-operating with the coupling organs and being controlled by a control unit (45) depending on signals fed to the control unit representative of various engine and vehicle data. The invention is characterized in that the manoeuvring organs (40, 41, 42) are arranged to, in the case of in-signals to the control unit (45) which indicate a predetermined driving condition at which the fuel consumption of the vehicle is optimally low, be set by means of the control unit (45) so that a synchronized gear engaged at the time is placed in neutral position, and in that the manoeuvring organs (40, 41, 42) are arranged to deactivate said neutral position when said driving condition is no longer present. By means of the invention, a gear box is obtained which permits a lowered fuel consumption of an associated engine.

摘要： A method is provided to control a drivetrain of a vehicle, especially a utility vehicle, wherein the drivetrain includes an engine with a cooling system. The cooling system includes a fan. The cooling system and the drivetrain are controlled by an electronic control unit (ECU). The ECU has access to a navigation system with topographic data. The method includes determining a topology of an upcoming route of the vehicle, estimating the load of the engine dependent of the topology of the upcoming route, estimating a temperature variation of the cooling system during the upcoming route, and controlling the drivetrain dependent on the estimated temperature variation, such that an actual temperature of the cooling system is kept below a temperature threshold value during the upcoming route of the vehicle. The temperature threshold value is dependent on a temperature at which said fan is activated.

摘要： A method and a system for automatic freewheeling of a vehicle, where in the vehicle is arranged a speed-lowering arrangement, including an engine, a wheel driven by the engine via an automated stage-geared gearbox, a gas pedal for regulating the driving torque of the engine, and a control unit. The control unit is arranged to, when the freewheel function is activated and in the presence of an input signal indicating that a predetermined vehicle speed limit is exceeded, to automatically deactivate the freewheel function and brake the vehicle with the speed lowering arrangement. The control unit is arranged to reactivate the freewheel function in the presence of an input signal indicating that the vehicle speed has fallen to close to the predetermined vehicle speed limit. The future progression of the vehicle may be simulated with a view to optimizing the freewheel function in terms of good fuel economy and/or increased comfort.
