摘要:
A method for operating a drivetrain of a motor vehicle having in the force flow direction and in the following order an internal combustion engine, a clutch, an electric motor, a transmission and an axle gearset, or an internal combustion engine, a clutch, an electric motor, a transmission input shaft, a transmission and an axle gearset. The electric motor is used for pre-lubricating and warming the transmission such that, with the vehicle clutch disengaged, the lubricant pump of the transmission is driven by the electric motor so bearings are supplied with lubricant before the engine is started, and the heat, produced by splashing the lubricant, additionally warms the transmission.
摘要:
A method for operating a drive train of a vehicle in which the drive train has at least an internal combustion engine, an engine clutch, an electric machine, a single and a multi-group manual transmission with synchronized and/or unsynchronized shift elements for shifting gears, an axle transmission, as well as an associated control device for controlling the gear shifts. It is provided for the purpose of expanding the functional possibilities, that the electric machine is used, during gear shifts in the manual transmission, as a mode of synchronization, a synchronization aid, or at least as a shifting aid such that changes in the direction of rotation of the transmission shafts are taken into consideration.

摘要:
A device for controlling a fluid-actuated, double-action operating cylinder (2) having two cylinder chambers (6, 8) separated from one another by a piston (4). Each cylinder chamber (6, 8) communicates with a respective valve (12, 14) for controlling the flow of fluid in and out of the cylinder chamber (6, 8) and a pressure sensor (40) for detecting the fluid supply pressure. A control unit (20) is connected to the switching valves (12, 14) and the pressure sensor (40). To determine the actual control force of the operating cylinder (2), the pressure sensor (40) is arranged between the cylinder chambers (6, 8) and the control unit (20). The output from the pressure sensor (40) can be processed in the control unit (20) and used for actuating a pressure regulation valve (22) arranged in the pressure line (32).
摘要:
A method for controlling the driving operation of motor vehicles in which specific driving conditions are detected by rotational sensors located at individual wheels and/or sub-assemblies in the power train, and are then evaluated in a control unit and converted into control commands for specific functions of the vehicle or into warning signals. ABS, ASC or EBS systems as well as automatic gearboxes are controlled in this manner. Rotational sensors detect the current rotational direction and additionally determine of the presence of a rotary motion. The rotation sensors permit numerous functions of the vehicle to be controlled in a simple manner and with the aid of various parameters obviate the need for the calculation of the rotational direction by way of the determination algorithms.

摘要:
A method for controlling and regulating a transmission brake which, for the purpose of synchronization, determines a target rotational speed of a shaft that is to be synchronized on the basis of an actual rotational speed of a transmission shaft, and controls a transmission brake such that the determined target rotational speed is set for the shaft that is supposed to be synchronized. The transmission brake also carries out additional functions. These functions require no, or only minimal, additional hardware complexity in a cost-neutral way, but considerably increase the functional and practical value of the transmission brake. The comfort and speed of shifting operations, the protection, or as the case may be the detection of error states in sensors, clutch, main clutch, and motor control are improved, and undesirable transmission states avoided. It is also possible to account for and influence other conditions, such as the operation of ancillary devices.
摘要:
A transmission, such as an automated manual transmission for a motor vehicle, with at least one shift group, such that the shift group or each shift group comprises a shift rail which actuates a shift fork that co-operates with a shift sleeve of the shift group concerned. Associated with the shift rail of the shift group or of each shift group there is a sensor that moves together with the respective shift rail relative to a corresponding measurement receiver such that in the area of at least one shift group, a first relative position between the measurement receiver and the sensor in the actuation direction and a second relative position between the measurement receiver and the sensor perpendicular to the actuation direction of the shift rail concerned can be detected, and from the second relative position, an evaluation device deduces system conditions of the shift group concerned.
