摘要： A control method for an engine of a vehicle includes generating a brake value indicative of an operating condition of a brake system of the vehicle, and selectively adjusting one of a fuel control value of the engine and a fuel adjustment diagnostic value for the engine based on the brake value. In the method, a mass of fuel delivered to the engine is based on the fuel control value, and a diagnostic result indicative of lean operation of the engine is based on the fuel adjustment diagnostic value. The brake operating condition is selected from a group including a state of operation, a pedal displacement, an actuation period, a fluid operating pressure, and a power assist pressure. The fuel control value is provided.

摘要： A dual voltage tandem engine start system provides a method for high rotational speed, low emissions, heat-engine start-ups in a hybrid electric vehicle. The system also provides a reliable backup system that can be jumpstarted in an emergency should part of the vehicle's electrical system fail. At start-up, a conventional low voltage starter motor (typically 12-volt) begins turning the heat engine up to a predetermined initial engine RPM. When this RPM is reached, a higher voltage motor/generator, in tandem with the low voltage starter motor, also begins turning the heat engine. Once a second, predetermined heat engine RPM is reached, the low voltage starter motor stops turning the engine, leaving the motor/generator to turn the heat engine to a final engine RPM where it begins fueling and combustion starts. This final engine RPM is sufficiently high to allow a low engine emission start once fueling begins.
