In a differential limiting torque control section, a target differential rotation speed between front and rear drive shafts is established according to a dial position inputted by a driver of a variable dial. Further, an actual differential rotation speed between front and rear drive shafts is calculated and a deviation between the target differential rotation speed and the actual differential rotation speed is calculated. Based on the deviation, a first differential limiting torque and based on a dial position of a variable dial a second differential limiting torque are calculated. Further, a third differential limiting torque is calculated based on the dial position and a throttle opening angle. A final differential limiting torque between front and rear drive shafts is obtained by summing up these first, second and third differential limiting torques.

The present invention relates to a system for controlling driving modes of a vehicle having a driver, wherein each of said driving modes is adapted to control a behaviour of said vehicle during operation of the vehicle in said driving mode, each of said driving modes being associated with a set of driving sub-modes, wherein each driving sub-mode is adapted to be activated by the vehicle in response to ambient circumstances. One of said driving modes is associated with a first and a second driving sub-mode, said first and second driving sub-modes being accompanied with a first and a second driver controlled setting respectively. The system further comprises input means for selection between said driving modes and for controlling said driver controlled settings when applicable, wherein said first and second driver controlled settings are adapted to be manually set by the driver through said input means only upon activation of the accompanying driving sub-mode by the vehicle.

When fail signals from first and second inverters are rendered inactive, i.e., when all inverters are proper, an ECU renders first and second shut down permit signals active for output to first and second AND gates regardless of the operating state of motor generators. The first AND gate takes an AND operation of the fail signal from the second inverter and the first shut down permit signal to output a shut down signal to the first inverter. The second AND gate takes an AND operation of the fail signal from the first inverter and the second shut down permit signal to provide a shut down signal to the second inverter.

In a differential limiting torque control section, a target differential rotation speed between front and rear drive shafts is established according to a dial position inputted by a driver of a variable dial. Further, an actual differential rotation speed between front and rear drive shafts is calculated and a deviation between the target differential rotation speed and the actual differential rotation speed is calculated. Based on the deviation, a first differential limiting torque and based on a dial position of a variable dial a second differential limiting torque are calculated. Further, a third differential limiting torque is calculated based on the dial position and a throttle opening angle. A final differential limiting torque between front and rear drive shafts is obtained by summing up these first, second and third differential limiting torques.

The invention relates to a driver assistance device for a motor vehicle, comprising a drive assembly (1) which can be connected to a powertrain (5) via an actuator-activatable clutch (3), said clutch being part of an electronically controlled clutch system in which a clutch pedal sensor (19) detects a driver-side actuation of a clutch pedal (17) and in which an analysis unit (21) ascertains a clutch torque (M) using the detected clutch pedal actuation and actuates the clutch (3) with a corresponding clutch signal (SKI) in a first control mode (I). According to the invention, an input unit (31) is paired with the analysis unit (21) for a driver-side adaptation of the clutch behavior, and when the input unit is actuated by the driver, a switch-over is carried out between the first control mode (I) and at least one second control mode (II).
