摘要:
Drivetrain for a motor vehicle including an engine (1), a gearbox (9) having an intermediate shaft (11) with intermediate shaft brake (17) and a friction clutch (3) coupled between the engine and the gearbox. A torque sensor (19) is provided, which detects the input torque to the gearbox. The intermediate shaft brake and the clutch are controlled by a control unit (12), which is programmed in predetermined instances, when the gearbox is in the neutral position, the clutch is engaged and the intermediate shaft brake is released, to measure and store the torque loss from the gearbox and then to set the brake to a predetermined level and to register and store the torque increase during the setting until constant torque is attained. This is registered and stored in the control unit together with the time for the torque increase. The control unit is programmed to then deactivate the brake and to register and store the torque reduction during deactivation down to the torque loss and the time taken for this.
摘要:
Method and apparatus for distributing brake torque between at least one first and one second brake device on a motor vehicle including at least two wheel pairs. The first brake device is a friction brake which acts on at least one wheel pair and the second brake device acts on at least the driven wheel pair via the transmission and is disposed before the clutch device of the transmission. Brake torque is distributed between the first and the second brake device in a manner that compensates for the loss of brake torque which occurs when the second brake device is disengaged by the clutch device of the transmission.
