Abstract: A driver assistance device for a motor vehicle with a drive assembly, which can be connected to a drivetrain via a clutch that can be activated by an actuator. The clutch being a component of an electronically controlled clutch system, in which a clutch pedal sensor detects an actuation of a clutch pedal on the driver's side and in which an analysis unit determines, in a first control mode on the basis of the detected clutch pedal actuation, a clutch torque and actuates the clutch with a corresponding clutch signal. For an adjustment of the clutch response on the driver's side, the analysis unit is associated with an input unit, for the actuation of which, on the driver's side, it is possible to shift between the first control mode and at least one second control mode.

Abstract: A clutch control device is provided for a four-wheel drive vehicle. The clutch control device is able to suppress the elevation of the temperature of the oil supplied to a friction clutch during two-wheel drive travel when the friction clutch is released. The clutch control device includes a dog clutch and an electronic control coupling. The friction clutch is housed in a coupling case. When the dog clutch and the friction clutch are released, a two-wheel drive mode is selected. The coupling case has a passage opening that is closed to retain lubrication oil in an oil chamber with respect to a clutch chamber that houses the friction clutch. When oil stirring conditions are met thereafter, the passage opening is opened and the lubrication oil is allowed to flow into the clutch chamber from the oil chamber.

Abstract: A method is provided for protecting an all-wheel drive clutch of a two-axle vehicle with clutch-controlled all-wheel drive. A power braking situation, where both the accelerator pedal and the brake are actuated and the vehicle is stationary or moves only slightly in the vehicle longitudinal direction, may be critical for the all-wheel drive clutch. For example, when the friction coefficient of the primary axle is very small and the wheel braking torque is less than the driving torque, a clutch slip may occur at the all-wheel drive clutch. Upon detecting a power braking situation, a protective measure is implemented against thermal overload of the all-wheel drive clutch, such as reducing or limiting the engine torque output, so that the clutch slip and the energy input into the all-wheel drive clutch are reduced.
