  • Patent number: 9002533
    Abstract: A message generation module generates a message that is to be transmitted to a serial data bus of the vehicle once per first predetermined period. A queue manager module resets a timer value when the message is added to a transmit queue and selectively adds the message to the transmit queue when: a number of messages in the transmit queue is less than a first predetermined value; the timer value is greater than the first predetermined period; and one of (i) the first predetermined period is less than a second predetermined period and (ii) the first predetermined period is greater than the second predetermined period and the number of messages in the transmit queue is less than a second predetermined value. The second predetermined value is less than the first predetermined value. A communication control module selectively transmits messages from the transmit queue to the serial data bus.

  • Patent number: 8631891
    Abstract: A vehicular powertrain system includes an engine, an electro-mechanical transmission and an electric machine arranged in an input-split hybrid configuration. A control system for the powertrain system includes a control module signally connected to a plurality of input devices and configured to execute program code stored on a computer readable medium to control the powertrain. The program code monitors operator inputs, determines an intent to service the vehicle based upon the operator inputs, commands the electric machine to generate a net torque output of zero, and controls the engine speed correlative to an operator depression of an accelerator pedal.

  • Patent number: 8271173
    Abstract: A control method for vehicular hybrid powertrain system includes monitoring operator inputs to an accelerator pedal and a transmission gear selector, and determining an operator torque request based upon the operator inputs to the accelerator pedal and the transmission gear selector. Torque output from the electric machine is commanded based upon the operator torque request. Engine output is controlled based upon the operator torque request and the commanded torque output from the electric machine. Vehicle hood position is monitored and the engine output is controlled correlative to the operator input to the accelerator pedal when the monitored position of the vehicle hood is open and the operator input to the transmission gear selector is one of a PARK and a NEUTRAL position.
