  • Patent number: 11027592
    Abstract: A vehicle climate control system includes a heat exchanger to heat ambient air using engine waste heat, and a plurality of positive temperature coefficient (PTC) heating elements to heat air passed through the heat exchanger. The vehicle also includes a controller programmed to, while the vehicle is driven without engine propulsion, issue a command to sequentially de-energize the PTC heating elements before an upcoming engine activation. The sequential de-energization of the PTC heating elements is performed according to a schedule that is based upon a power surge dissipation time.

  • Publication number: 20210043015
    Abstract: Methods and systems are provided for restarting an engine following an engine idle-stop. In one example, a method may include, following a first unsuccessful engine restart attempt, prompting a driver, via a human machine interface (HMI) to apply a brake pedal and upon application of the brake pedal, carrying out one or more restart attempts. If the driver does not apply the brake pedal within the threshold duration, the driver may be prompted to manually restart the engine.

  • Patent number: 10704676
    Abstract: A transmission assembly including a clutch system, an accumulator, and a controller is provided. The clutch system may include a flow source. The accumulator may be selectively in communication with the flow source via a solenoid valve. The controller may be programmed to, responsive to detection of a vehicle stop and the accumulator charged below a predetermined threshold, output a command to open the solenoid valve to rapidly charge the accumulator from the flow source. The predetermined threshold may be an accumulator pressure between 700 kPa and 900 kPa. The controller may be further programmed to, responsive to detection of the accumulator being charged to or above the predetermined threshold, output a shut down command to an engine in communication with the transmission assembly and to output a close command to the solenoid valve. The flow source may be a pump out circuit or a line pressure circuit.

  • Patent number: 10597024
    Abstract: A vehicle includes an engine cranked by an electric machine powered by a first battery, a first plurality of components powered by the first battery, a second plurality of components powered by a second battery, and a processor programmed to isolate the second battery and associated components from the first battery and associated components at least during engine cranking. The first battery may be a low voltage battery having a first chemistry, such as a lead-acid battery with associated components that are less sensitive to voltage variation induced by engine cranking or starting, such as heated mirrors, seats, wipers, a climate control blower, power windows/doors, and auxiliary pumps. The second battery may be a low or high voltage battery having a second chemistry, such as a lithium-ion battery with associated components that may be more sensitive to low voltage during engine cranking/starting, such as lighting, electronics, and infotainment systems.

  • Patent number: 10449945
    Abstract: A hybrid electric vehicle (HEV) that includes an internal combustion engine and a climate control system (CCS) coupled to controllers configured to auto start-stop the engine when the HEV decelerates to an engine-stop threshold speed. The controllers are also configured to adjust a climate-fan-speed by a predetermined initial-factor, and at subsequent timed-intervals with a speed-factor that is adjusted from the initial-factor at each timed-interval, such that engine restart is inhibited by perceptually small speed adjustments and perceptually slow timed-interval cabin cooling adjustments. Such gradual adjustments are tuned to increase passenger perceptions of continuing cabin comfort, which reduce the likelihood that a passenger may adjust the CCS to require engine restart, and to increase auto stop-start fuel economy.
