    摘要: Power brakes are typically vacuum assisted, with the vacuum provided from the intake manifold. If the engine is commanded to operate for a long period at a condition with low intake manifold vacuum, the vacuum within the brake booster may drop to a level which is marginal or insufficient for a present or subsequent braking operation. To ensure sufficient vacuum in the intake manifold to provide to the brake booster, the engine may be commanded to operate at a condition to increase intake manifold vacuum by one of: adjusting cam timing, increasing engine speed, and increasing EGR. In the case of a stop-start vehicle, the engine speed is increased from zero to a condition that provides the desired vacuum.

    摘要: In the event that the brake pedal and accelerator pedal are depressed simultaneously, powertrain output is decreased monotonically with brake pedal input. In a lower range of brake pedal input, the brakes are prevented from actuating or are allowed to actuate minimally. In a higher range of pedal input, the powertrain output continues to be decreased and the brakes are allowed to actuate. In yet another higher range of pedal input, the powertrain output is substantially decreased such that a minimal powertrain output is achieved. The powertrain may include an internal combustion engine and/or an electric motor. The brake pedal input is determined based on a sensor associated with the brake pedal, the brake booster, or the master cylinder.

    摘要: A hybrid electric vehicle includes an internal combustion engine, a high voltage traction battery, an electric motor powered by the traction battery, an electric air conditioning (AC) system, and a controller. The controller is programmed to start the vehicle. The vehicle is started by, if a climate control demand requires cooling: (a) if a vehicle start request is a remote start request, starting the engine; (b) if the vehicle start request is a local start request, avoiding starting the engine to provide a silent start.

    摘要: A method and system are described for extending an operating range of a motor vehicle, the vehicle having a first mode of operation and an economy mode of operation. A vehicle range may be estimated based on a vehicle fuel level and the first mode of operation. A distance to a fuel location may also be estimated. The economy mode of vehicle operation may be automatically entered a predetermined period of time after the estimated vehicle range based on the vehicle fuel level and the first operating mode decreases to within a predetermined threshold of the estimated distance to a fuel location.
