  • Patent number: 11326657
    Abstract: A method for operating an electrohydraulic transmission clutch of a motor vehicle, wherein, for a clutch operation, a hydraulic pressure is set by way of a regulating device of a controller as a function of a clutch signal, and, through the pressure, a disengagement element of the transmission clutch is moved through a soft region into a rigid region via a rigid point, or vice versa. The soft region is to be compensated for. Further, as a function of the clutch signal, the regulating device generates a preliminary target value signal for the pressure and a time derivative of the preliminary target value signal is generated as a movement signal, and a pilot control generates a pilot control signal as a function of the movement signal, and the preliminary target value signal and the pilot control signal are combined to give a final actuating value signal for the pressure.

  • Patent number: 11320004
    Abstract: The disclosure relates to an overrunning clutch, comprising a torque-introducing clutch element, a torque-receiving clutch element and switching element, which is forced from an engagement position into a freewheeling position or from a freewheeling position into an engagement position in dependence on the direction of a sufficient change in the rotational angle position between the torque-introducing clutch element and the torque-receiving clutch element by means of an actuating force applied to the switching element by an actuator. According to the disclosure, the actuating force is a friction-induced actuating force, which is induced by means of a friction-force pairing between the actuator and a component of the overrunning clutch that is in frictional contact with the actuator and the actuator forms an interlockingly acting actuating stop, by means of which the actuating force acts on the switching element.

  • Patent number: 11307042
    Abstract: Systems including one or more sensors, coupled to a vehicle, may detect sensor information and provide the sensor information to another computing device for processing. The processing may include analyzing the sensor information to identify one or more risk objects, such as animals, pedestrians, potholes, etc. The processing may further include generating a three-dimensional (3D) risk map, which may be displayed to a passenger in the vehicle. The 3D risk map may illustrate the one or more risk objects as one or more point clouds, respectively, within a virtual world representation of the vehicle's surroundings. Such a display may be used to alert drivers to possible risks while driving. In case of an accident, the 3D risk map may also be leveraged by insurance providers to process insurance claims and to notify customers that an insurance claim has been established.

  • Patent number: 11267362
    Abstract: Systems and methods are provided for dynamically selecting a control policy from among several available control policies for controlling an electric vehicle fleet charging system. A control policy may take into account fluctuating local renewable generation and/or time of use electricity pricing. The performance of the selected control policy is monitored and a different control policy may be deployed in its place if the different control policy has a higher chance of providing better performance given the current control environment. Thus, as the control environment changes, the control policy that controls the power system may also be changed in an adaptive manner. In this way, the control policies may be changed as the control environment changes to provide an improved real-time performance compared to the use of a single control policy.

    Abstract: A clutch assembly includes an outer ring having a first and second pocket, and an inner ring. A strut and pawl may be disposed within the first and second pockets. The pawl may be configured such that rotation of the strut pushes the pawl toward teeth of the inner ring for engagement therewith. In a first mode of operation, the pawl does not contact the teeth and the inner ring is free to rotate in the first and second rotational directions. In a second mode of operation, the pawl is in partial engagement with the teeth and the inner ring is free to rotate in the second rotational direction and prevented from rotation in the first rotational direction. In a third mode of operation, the pawl is in full engagement with the teeth and the inner ring is prevented from rotation in both the first and the second rotational directions.

  • Patent number: 11248666
    Abstract: A system is configured to control a clutch that connects a first rotating body and a second rotating body. The system includes a biasing portion, an actuator, an energization device, and a control unit. The biasing portion permanently biases the clutch in a connecting direction. The actuator drives the clutch in a disconnecting direction. The energization device energizes the actuator. The control unit controls the energization device. The energization device outputs a first current value to the actuator when a connection of the clutch is detected even if a condition for permitting a disconnection is satisfied. The energization device outputs a second current value lower than the first current value when the condition for permitting the disconnection is satisfied and a disconnection of the clutch is detected.
