  • Patent number: 9383007
    Abstract: A vehicle includes an engine, a transmission with a shift valve, an alternator, an auxiliary battery, a voltage sensor operable to measure an auxiliary voltage, and an electronic transmission range selection (ETRS) system. The ETRS system includes a controller, and also an electronic range selector device that transmits an electronic range request signal to the controller to request the shift of the transmission to a requested operating range. The controller executes a method to predict a loss of auxiliary power aboard the vehicle, and to control an action of the vehicle in response to the predicted loss of auxiliary power. The electronic range request signal is received from the range selector device and auxiliary voltage. The controller calculates a slope of a decrease in the measured auxiliary voltage. A control action is executed with the alternator is in the charging state and the calculated slope exceeds a calibrated slope threshold.

  • Patent number: 8543286
    Abstract: A method includes: receiving classification data for a hazard associated with a system of a vehicle, the classification data indicating a classification of the hazard under standard 26262 of the International Organization for Standardization (ISO); receiving fault tree data for a fault tree of the hazard; analyzing the fault tree data using a fault tree analysis (FTA) application; identifying a minimal cut-set for the hazard; retrieving standards data for the hazard based on the classification of the hazard, the standards data indicating a minimum value for minimal cut-sets under the 26262 standard; comparing a number of elements in the minimal cut-set with the minimum value; and indicating whether the minimal cut-set complies with the 26262 standard based on the comparison.

  • Patent number: 6600988
    Abstract: A method for controlling a powertrain of a vehicle is described. The method determines a desired vehicle condition based on three driver actuated elements. In a preferred embodiment the first element can be pedal position, the second element can be a brake actuator or, more specifically, brake actuation duration, and the third element can be a gear selection lever. Further, the desired vehicle condition can be desired powertrain output, vehicle acceleration, or various other parameters.
