  • Patent number: 8634987
    Abstract: A creep travel capability of an electric vehicle is secured when an abnormality occurs in a brake sensor. When an accelerator operation amount reaches 0% in a low vehicle speed region, a target creep torque is set, whereupon a motor-generator is controlled toward the target creep torque. The target creep torque is reduced as a brake pedal is depressed in order to suppress heat generation and the like in the motor-generator during vehicle braking. Hence, in an electric vehicle in which the target creep torque is varied in accordance with the brake operation amount, when an abnormality occurs (step S11) in a brake sensor for detecting a brake operation amount, a preset prescribed creep torque is employed as the target creep torque regardless of the brake operation amount (step S15). The prescribed creep torque is set at a required magnitude for securing the creep travel capability.

Responsive to a further determination, the vehicle diagnostic device may transmit the obtained diagnostic data to the one or more display devices via the second separate vehicle diagnostic device. The further determination may be based on one or more of wireless connectivity status, power level status, transmission power requirements, or other facts or determinations.

  • Patent number: 8558713
    Abstract: A weight based occupant detection device that includes a weight sensing device installed in a vehicle seat in a manner effective to sense weight on a seating surface. The weight sensing device is configured to output a weight signal indicative of an occupant weight of a seat occupant residing on the vehicle seat. The occupant detection device also includes a seat orientation angle sensing device that is configured to output an orientation angle signal indicative of a seat orientation angle. The occupant detection device may also include an accelerometer for sensing vertical acceleration of the vehicle seat, and a seat backrest angle device for measuring the angle of the seat backrest. The occupant detection device compensates a signal from the weight sensing device for errors caused by seat orientation, seat vertical acceleration and seat backrest angle.

  • Patent number: 8494711
    Abstract: An automated start/stop system for a vehicle comprises an auto-stop module, a diagnostic module, and an auto-start module. The auto-stop module selectively initiates an auto-stop event and shuts down an engine while the vehicle is running. The diagnostic module selectively diagnoses a fault in a clutch pedal position sensor of the vehicle. The auto-start module, while the vehicle is running and the engine is shut down, selectively initiates an auto-start event after the fault has been diagnosed when current drawn by a starter motor is less than a predetermined maximum starting current.
