Estimating the term…
The operation of an automated friction clutch between the output element of the engine and the input element of the variable-speed transmission in a motor vehicle is regulated by a fluid-operated system which receives signals from an evaluating circuit. The evaluating circuit receives signals from a number of sensors which monitor the RPM of the engine, the RPM of the input element of the transmission, clutch travel, the position of the throttle valve, the position of the shift linkage, the position of the gas pedal and other parameters. The fluid-operated system can select the condition of the clutch during starting, driving, acceleration, parking, driving in reverse and/or parking of the motor vehicle and/or during transitions between such stages of operation.
A method of regulating the operation of an automatic friction clutch, which is installed between a prime mover and a transmission in a power train of a motor vehicle, during at least one of various stages of operation including starting, driving, accelerating, braking, driving in reverse and parking of the vehicle and shifting of transmission into different gears as well as during transitions between said stages, comprising the steps of monitoring--at least for the purpose of starting the vehicle--at least one selected parameter including measuring the torque in the power train and/or the angular positions of clutch parts while the condition of the clutch is being changed from clutch-open, with the vehicle at a standstill and with the transmission in a gear other than neutral, at a predetermined speed toward clutch-closed to an extent such that the clutch transmits a torque less than that which is required to set the vehicle in motion;
A method of regulating the operation of an automatic friction clutch, which is installed between a prime mover and a power train in a motor vehicle wherein the power train has a transmission with at least one rotary element, during at least one of various stages of operation including starting, driving, acceleration, braking, driving in reverse and parking of the vehicle and shifting of transmission into different gears as well as during transitions between said stages, comprising the steps of monitoring--at least for the purpose of starting the vehicle--a selected parameter of the clutch while the condition of the clutch is being changed from clutch-open, with the vehicle at a standstill and with the transmission in neutral gear, at a predetermined speed toward clutch-closed to an extent such that the clutch transmits torque to the at least one rotary element so that the at least one rotary element rotates at less than idling speed of the prime mover;
