  • Publication number: 20240100992
    Abstract: A vehicular control system includes an electric motor operable to, when powered, drive one or more wheels of a vehicle, a primary battery operable to provide electric power to the electric motor, and a backup battery operable to provide electric power to the electric motor. When a switch is operating in a first state, the primary battery provides electric power to the electric motor and the backup battery does not provide electric power to the electric motor. When the switch is operating in a second state, the backup battery provides power to the electric motor and the primary battery does not provide electric power to the electric motor. The system, via processing of the battery status information of the primary battery, determines a failure of the primary battery. The system, responsive to determining the failure of the primary battery, adjusts the switch from the first state to the second state.

  • Publication number: 20230080530
    Abstract: A vehicular sensing system includes a first set of first sensors disposed at a first rear portion of a vehicle. The system includes a second set of second sensors disposed at a second rear portion of the vehicle that is above the first rear portion of the vehicle. A respective first field of sensing of at least one first sensor at least partially overlaps a respective second field of sensing of at least one second sensor. The system includes an electronic control unit (ECU) for processing sensor data to detect objects that are located within the at least partially overlapping fields of sensing of the at least one first sensor and the at least one second sensor. The vehicular sensing system, responsive to detecting the objects that are located within the at least partially overlapping fields of sensing, determines three-dimensional locations of the detected objects relative to the vehicle.

  • Patent number: 5384949
    Abstract: A torque transmitting structure for an automatic transmission has an inner hub for rotating the structure and an outer annular shell. The annular shell has an internal radial spline portion, an external brake surface, a torque tube and an axially facing drive connecting surface. The annular shell is manufactured in a flow forming process, wherein a cup-shaped blank is secured on a mandrel which has a shape complementary to the internal shape of the shell. Forming rolls engage the outer surface and are moved axially relative to the mandrel in a manner to form the desired outer contour of the shell. After the flow forming operation, the shell is removed from the mandrel, the axial drive connection is formed by metal removal and the hub is bonded to the shell.
