A method of controlling a clutch for vehicle may include determining, by a controller, raised offset engine torque, when engine torque is raised to a reference torque or more in an engine idle state, and controlling, by the controller, the clutch based on the determined offset engine torque.

A vehicle, in the drivetrain of which a clutch, in particular a wet-running multi-disc clutch, is connected as a starter element between an internal combustion engine and a transmission, having a clutch controller, which, as a function of current driving operation parameters, determines a setpoint clutch torque and actuates a clutch actuator with a manipulated variable correlating with the setpoint clutch torque, in order to set at the clutch an actual clutch torque, which manipulated variable is determined as a function of the setpoint clutch torque and of a coefficient of friction stored in the clutch controller in an actuation unit of the clutch controller, and having an engine controller, which determines an actual engine rotational speed and an actual engine torque, and, in a stationary state of the vehicle with the internal combustion engine running, regulates the actual engine rotational speed to a predefined idling rotational speed.

A method may be provided for correcting a raw signal supplied by a pressure sensor in an all wheel drive system having a hydraulic pump and a hydraulic fluid. The method may include measuring the raw signal supplied by the pressure sensor, determining when the all wheel drive system is in a state where the hydraulic fluid is at a known pressure determined independently from the pressure sensor, determining a new zero-point offset by comparing the raw signal to a voltage value associated with the known pressure, and creating a corrected voltage signal by adjusting the raw signal based on the new zero-point offset. This corrected voltage signal may be converted into a pressure reading for controlling the all wheel drive system.

A vehicle control system for a vehicle including an engine having a plurality of cylinders, a power transmission route between the engine and drive wheels and a clutch device for selectively connecting and disconnecting the power transmission route. The vehicle control system can disconnect the power transmission route during running to allow the vehicle to coast. The vehicle control system including an electronic control unit (ECU) for detecting, among other things, vehicle speed and operation of an accelerator by a driver, as well as for executing and controlling various components of the vehicle.
