摘要： The invention relates to a device for controlling an automatic gearbox, particularly for a motor vehicle, of the type including means (1, 2, 3) for selecting the position of the gearbox, namely of the main operating mode of the latter (P, R, N or D) and the ratios (''3'', ''2'', ''1'') allowed in forwards travel, the means being connected to a unit (6) for processing data and controlling means (8, 14) for positioning the gearbox depending on the selection means and on the speed of the vehicle, according to at least one gear change law. This device is characterised in that the data-processing unit (6) is connected to means (17) by which the user can actuate at least one forced operating mode of the gearbox, in which the data-processing unit (6) determines permissible limiting ratios (gears) for the gearbox, with the aid of at least one gear change law, substituted for that of the means for positioning this gearbox.

摘要： The present invention relates to an adaptive correction of servo activating hydraulic fluid pressure during shift. In one embodiment according to the present invention, a ratio of a mass airflow rate of intake air admitted to an engine (Qa) to a revolution speed of a transmission output shaft (No) is calculated, and a first parameter (TqSEN) is determined in response to the ratio (Qa/No). Besides, a second parameter (No) is the transmission output shaft speed (No). The servo activating hydraulic fluid pressure is determined in response to this first and second parameters. In another embodiment, a turbine shaft speed (Nt) is calculated from the output shaft speed (No) and a gear ratio (g) of a gear position established before shifting. The turbine shaft revolution speed (Nt) is used instead of the output shaft speed (No) in determining the first parameter (TqSEN).

摘要： The method involves implementing protection functions for one or more temperature stages, whereby the functions of the gearbox are restricted in a controlled manner depending on the temperature stages. Threshold temperatures are defined that in turn define the temperature stages. The gearbox temperature is used as the control parameter oir control signal for entering and exiting the protection functions and/or temperature stages.

摘要： A method for controlling a damper clutch of an automatic transmission that can perform a normal shifting quality by selecting a correction value according to an outside air temperature for direct connection of the damper clutch and delaying the direct connection of the damper clutch until the operational oil temperature rises by considering the correction value to thereby enable it to get to an appropriate degree of operational oil temperature, a normal state of operational oil, the method for controlling a damper clutch of an auto transmission comprising the steps of: detecting the outside air temperature; correcting oil temperature to determine a point of time for direct connection of the damper clutch according to the determined outside air temperature; and performing controlling operations for direct connection of the damper clutch with a requirement that the operational oil temperature reaches to the correction value.

摘要： A system and method for controlling a vehicular powertrain including an internal combustion engine, an automatic transmission having a plurality of selectable gear ratios, and a controller in communication with the internal combustion engine, the transmission, and an accelerator pedal, include determining a driver requested wheel torque based on position of the accelerator pedal, and determining a vehicle speed ratio changing threshold based on the driver requested wheel torque. In one embodiment, the system and method determine a value indicative of current barometric pressure, determine a current gear ratio, and modify the driver requested wheel torque based on the current barometric pressure and the current gear ratio to determine a compensated wheel torque. The compensated wheel torque is used to determining the ratio changing threshold. Offset values are included to adjust for barometric pressure variation, transmission oil temperature, and to prevent gear hunting or excessive ratio changing.

摘要： When a cold start condition exists, an electronic gear control (4) calculates for an automatic transmission (3) driven by an internal combustion engine (1) the energy throughput of the internal combustion engine (1). The energy throughput is added up and compared with a limit value. The shift points of the automatic transmission (3) are pushed up to higher values as long as the calculated value remains less than the limit value.

摘要： A hydrostatic drive in a car for both the cooling fan of a heat exchanger and the generator uses a load pressure-controlled pump driven by the engine. Each circuit uses a hydromotor supplied with pressurised fluid by the pump, the two circuits being in parallel. The generator is run at constant speed. There are solenoid-operated proportional throttle valves (43) for the fluid to the hydromotors fed by an electronic control unit (60), which receives signals from a temperature sensor at the fan and a speed sensor at the generator. The control unit has a pre-defined program of operation. ADVANTAGE - Load on the pump is constantly matched to the requirements of the fan and the generator to maintain max. efficiency at all times.
