Abstract: A method of controlling a motor vehicle with an automated clutch is provided and includes the steps of: (a) detecting the vehicle speed, (b) detecting if the brake and/or the gas pedal is actuated, (c) detecting whether or not the engine is running, (d) disengaging the clutch if the engine is found to be running while the vehicle is found to be moving faster than a threshold speed, and if at the same time neither the brake nor the gas pedal is found to be actuated, and (e) subsequently re-engaging the clutch if the brake and/or gas pedal is found to be actuated. Prior to re-engaging the clutch, a transmission input rpm-rate is determined, and an engine rpm-rate is controlled in such a manner that that the respective rpm-rates of the engine and the transmission are brought towards a closer agreement.

Abstract: A method for automatically adjusting slip in an automatic friction clutch arranged between an engine and a gearbox of a motor vehicle. The clutch has a clutch-adjusting positioning drive which adjusts the clutch to a position which is defined by a position set-point signal. The clutch input speed and the clutch output speed are detected using speed sensors and a position set-point signal is produced according to the difference of the speeds (slip speed). The slip speed is equal to a predefined set slip value and is used as a control variable for the transmitted clutch torque. An engine torque is used as a control variable for the clutch instead of the clutch torque or as a complement thereto.

Abstract: Specific shift positions of an electrically actuated vehicle transmission, such as first to fifth, neutral and reverse gears, are detected by monitoring one or more characteristic electrical variables, e.g., actuator currents, during a shift movement of the transmission and by correlating increased or decreased levels of current with the arrival at or passage through the specific shift positions.

Abstract: In a method and apparatus for diagnosing a malfunction in a clutch actuator of a motor vehicle, the actual position of the clutch actuator is measured by a position sensor. Simultaneously, an estimated position of the clutch actuator is calculated by an emulation unit that emulates the function of the clutch actuator. Malfunctions of the clutch-actuator are diagnosed by comparing the actual, measured position to the estimated position.

Abstract: The comfort level gear shift motor vehicle with an automated gear-shifting transmission is determined by shift parameters, which are dependent on driving parameters and on a shift program mode. The shift program mode identified through a characteristic parameter, which can vary a range of parameter values corresponding to a range of shift program modes. The method has the steps of detecting current values the driving parameters, detecting a current value of the characteristic parameter, determining respective minimum and maximum values that each of said shift parameters can assume within the range of characteristic parameter values as a function of the current driving parameter values, calculating actual shift parameter values as intermediate values between said maximum and minimum values for each of said shift parameters based on said current value of the characteristic parameter, and performing the gear shift with the actual shift parameter values.

Abstract: A method of cooling on a cooling bed hot-rolled steel sections from rolling heat, wherein the sections, particularly rails, have section parts of different masses arranged at a distance from each other over the cross-section of the section, and an apparatus for carrying out the method. Initially, the heat quantities to be proportionally removed from the different section parts in dependence on their mass and temperature and the quantity of cooling medium required for this removal are determined and computed by using measuring equipment together with a computing unit by means of a computer program. Subsequently, cooling of the different section parts or their masses is carried out in a controlled manner in such a way that the section parts reach with as little time delay as possible the transformation line Ar3/Ar1 during the decomposition of the gamma-mixed crystal into ferrite and/or pearlite while releasing the transformation heat.

Abstract: A vehicle securing system to prevent a motor vehicle having an automated transmission with a clutch between the transmission and the engine from rolling away after turning off the ignition. The automated transmission includes a plurality of gears and a control device that receives signals representative of the vehicle's operating parameters and that processes them as well as engages the driver-selected transmission gear. The control device is operative after ignition shutoff for a predetermined time period, or is operative after ignition shutoff by operation of a brake pedal, and effects the engagement of a selected gear when the vehicle is moving at a speed that is lower than a predetermined threshold speed value.

Abstract: A motor vehicle has an automated clutch (2) and/or an automated transmission (3) that are operated by an actuator (11, 8) through control commands of a control device (7). At least some of the control commands depend on sensor input indicating whether or not the brakes of the motor vehicle are applied. To detect the actuation of the brakes, the motor vehicle uses two brake sensors or switches (71, 72) rather than only one, thereby providing an additional margin of safety in the operation of the vehicle.

Each cooling water pipeline has arranged thereat water boxes. The cooling water pipelines have cooling water pipes having an inner pipe diameter matching the inner diameter of the correlated cooling water pipeline.

Abstract: A motor vehicle (201) has an engine (201), a clutch (203), and a transmission (204) with a shift lever (230). A sensor (232) arranged at the shift lever (230) detects movements of the shift lever or forces applied to the shift lever. When the sensor (232) detects a movement or force, the activity is interpreted as a signal that the driver intends to shift gear. A detector system of the motor vehicle detects conditions such as the presence and magnitude of a mechanical play which can affect the process of shifting gears in the transmission (204).

A gear machine is arranged between the gear unit of the shear and the drive motor, wherein torsion-proof couplings are arranged between the gear unit or the shear and the gear mechanism and between the gear mechanism and the drive motor.

Abstract: The positions of a gear selecting lever in a combined automatically and manually shiftable transmission which is installed in the power train of a motor vehicle are monitored by a first sensor which transmits signals to a control circuit serving to initiate the operation of an actuator for the gear selecting lever. Certain positions of the lever are monitored and reported to the control circuit by one or more additional sensors which influence the operation of the actuator in the event of failure of the first sensor. One of the additional sensors can monitor a first range of positions of the lever including the position when the transmission is shifted into reverse gear, and another additional sensor can monitor a second range of positions of the lever including the position when the transmission is in neutral gear.
