摘要： Methods and systems are provided to heat a catalyst of an after-treatment system for a vehicle. The after-treatment system is powered by a battery. An operational parameter of the battery and the driving mode of the vehicle is determined. After receiving an indication that a first operational parameter threshold has been surpassed and a torque demand of the vehicle has been predicted, heat is provided to the catalyst of the after-treatment system based on the predicted torque demand of the vehicle surpassing a second operational parameter threshold.

摘要： A method of providing a heating cycle for an after-treatment system is described. The method comprises initiating a pre-charge cycle of a DCDC converter and determining a temperature of the after-treatment system. In response to determining the temperature of the after-treatment system is below a threshold temperature and the pre-charge is complete, the method further comprises operating a solid-state switch to electrically connect a high voltage power source to a heating element to of the after-treatment system, and heating the after-treatment system with the heating element until the after-treatment system reaches the threshold temperature.

摘要： Systems and methods for operating an engine of a vehicle that may be automatically stopped and started are disclosed. In one example, a speed at which a vehicle system induced automatic engine stop inhibit request is cleared may be adjusted to permit automatic engine stopping during a wide variety of driving conditions so that fuel may be conserved and the possibility of disturbing vehicle occupants may be reduced.

摘要： A system for providing electric creep in a manual transmission vehicle having an accelerator pedal, a brake pedal, and an engine uses an electric motor configured to provide creep torque to a transmission output shaft when the manual transmission is in neutral, the electric creep mode is activated and the engine is auto-stopped. The system may provide forward or reverse creep torque. The system may cancel the electric creep in response to a vehicle door opening, a driver unbuckling a seatbelt, or depressing the accelerator pedal or the clutch pedal, or shifting the manual transmission out of neutral.

摘要： Methods and systems are provided for dealing with a change of mind event during an automatic shut-down of an engine in which the speed at which a starter motor used to restart the engine is disengaged is based upon the comparison of current engine speed (N) with a cranking speed limit (SLIM). In one example, during an engine restart while the engine is spinning down, the starter motor may crank the engine to a threshold cranking engine speed adjusted based on a position of the gear.

摘要： A method and apparatus for warning a driver of a motor vehicle of a predicted collision with a stationary object. A proximity sensor is used to determine a position of an obstacle relative to the vehicle. A steering angle of the vehicle is determined and used to predict a trajectory of the vehicle. A collision zone on the vehicle is identified based on the vehicle trajectory, the collision zone being that spot or location on the vehicle which is predicted to contact the obstacle. A visual display within the vehicle (on the control panel, for example) provides a visual indication to the driver of the position of the collision zone on the vehicle and a predicted trajectory of the collision zone as the vehicle moves in accordance with the steering angle.

摘要： Methods and system are provided to heat a catalyst of an after-treatment system for a vehicle. The after-treatment system comprises a heating module having a plurality of heating elements. Each of the plurality of heating elements is independently operable to provide thermal energy to the catalyst of the after-treatment system. One or more of the heating elements of the heating module are selectively operated to provide heat to the catalyst based on an operational parameter of the after-treatment system.

摘要： A method of controlling the engine of a vehicle having a stop-in-gear (SIG) stop-start system comprises: a control module determining that a brake is being applied, based on an output from a brake sensor, and that a transmission is in an in-gear position, based on an output from a transmission sensor; and, while the brake is applied and the transmission is in an in-gear position, the control module causing the engine to start in response to detecting movement of a clutch pedal towards a released position based on an output from a clutch pedal sensor.
