  • Patent number: 8914195
    Abstract: A system for powering a steering angle sensor coupled to a steering wheel and a controller comprising a switch, coupled to the sensor and the controller. The switch is activated upon motion of the steering wheel or steering shaft. The switch, when activated, connects a power supply, such as a vehicle battery, to the sensor and the controller so that a new steering angle may be sensed and stored. After a predetermined period of time, the controller sends a signal to deactivate the switch and disconnect the power supply.

  • Patent number: 8762019
    Abstract: A method of operating a transmission device comprising at least one input shaft and at least two output shafts. Torque that is present at the input shaft can be distributed between the two output shafts with a variable degree of distribution which can be changed according to the operating state depending on a transmission capability of at least one shift element. When a request to set a predefined degree of distribution is received, a mechanical self-locking torque of the transmission device—which influences the degree of distribution between the output shafts and is dependent upon the torque present at the input shaft—is determined, and a difference between the mechanical self-locking torque and a target overall locking torque of the transmission device that is equivalent to the required degree of distribution is determined. The transmission capability of the at least one shift element is set depending on this difference.

  • Patent number: 8694224
    Abstract: A control system or method for a vehicle references a camera and sensors to determine when an offset of a yaw rate sensor may be updated. The sensors may include a longitudinal accelerometer, a transmission sensor, a vehicle speed sensor, and a steering angle sensor. The offset of the yaw rate sensor may be updated when the vehicle is determined to be stationary by referencing at least a derivative of an acceleration from the longitudinal accelerometer. The offset of the yaw rate sensor may be updated when the vehicle is determined to be moving straight by referencing at least image data captured by the camera. Lane delimiters may be detected in the captured image data and evaluated to determine a level of confidence in the straight movement. When the offset of the yaw rate sensor is to be updated, a ratio of new offset to old offset may be used.

  • Patent number: 8602151
    Abstract: A drive system for a motor vehicle with a continuously driven primary axle and a selectably driven secondary axle has a differential that acts between the wheels of the secondary axle, and has a torque transmission device for transmitting a drive torque to the differential. The torque transmission device has a clutch and a pump, wherein the pump produces a hydraulic pressure in a first pressure chamber of the clutch when a speed difference occurs between the primary axle and the secondary axle. The first pressure chamber is connected via a connecting line to a second pressure chamber, which is associated with an actuating member of the differential, so that the pressure produced by the pump also permits an at least partial locking of the differential. The first pressure chamber is connected to a low-pressure chamber through a first discharge line, in which is arranged a first control valve.

  • Publication number: 20130220722
    Abstract: A four-wheel-drive vehicle includes a dog clutch provided between a propeller shaft and an engine, a torque coupling provided between a rear differential and rear wheels, and an ECU that controls the dog clutch and the torque coupling. When a drive mode is switched from a two-wheel-drive mode where the transmissions of torque by the dog clutch and the torque coupling are both interrupted, to a four-wheel-drive mode, the ECU sets the amount of torque that is transmitted by the torque coupling to a first torque value (T1) to increase the speed of rotation of the propeller shaft, and then sets the amount of torque that is transmitted by the torque coupling to a second torque value (T2) that is lower than the first torque value (T1), and engages the dog clutch when the rotations of first and second rotary members of the dog clutch are synchronized with each other.
