A vehicle includes an engine and a battery, and is configured to perform external power feeding of supplying electric power to the outside of the vehicle. The vehicle includes an MG that generates electric power by using motive power of the engine, and an ECU that controls the engine and the MG. When an outside air temperature is below a reference temperature and an amount of remaining fuel of the engine is below a reference amount in a case where the external power feeding is to be performed, the ECU limits the driving of the engine.

Hybrid vehicle and method of controlling the same

An apparatus for starting an engine of a mild hybrid vehicle is disclosed having low and high voltage starting devices and controlled by an electronic controller. The electronic controller is operable to use the high voltage starting device as a motor to crank the engine whenever possible so as to partially discharge a high voltage battery and facilitate the increased use of automatic stopping and starting of the engine.

Apparatus and method for starting an engine

A hybrid vehicle propulsion includes an engine and a first electric machine, where each is configured to selectively provide torque to propel the vehicle. The propulsion system also includes a second electric machine coupled to the engine to provide torque to start the engine from an inactive state. A high-voltage power source is configured to power both of the first electric machine and the second electric machine over a high-voltage bus. The propulsion system further includes a controller programmed to deactivate the engine and propel the vehicle using the first electric machine in response to the vehicle being driven at a steady-state speed for a predetermined duration of time. The controller is also programmed to restart the engine using the second electric machine powered by the high-voltage power source.

Hybrid vehicle propulsion systems and methods

A method and an apparatus for controlling a hybrid electric vehicle are provided The apparatus includes a navigation device that provides information regarding a gradient, a speed limit, and a traffic speed of a road An accelerator pedal position detector detects a position of an accelerator pedal and a brake pedal position detector detects a position of a brake pedal A vehicle speed detector detects a vehicle speed, a state of charge (SOC) detector detects an SOC of a battery, and a gear stage detector detects a gear stage that is currently engaged A controller operates the hybrid vehicle based on signals of the navigation device, the accelerator pedal position detector, the brake pedal position detector, the vehicle speed detector, the SOC detector, and the gear stage detector

Method and apparatus for controlling hybrid electric vehicle

A hybrid vehicle includes an engine and an electric machine, both capable of propelling the vehicle. The electric machine is electrically connected to a high voltage traction battery. The state of charge of the battery can decrease if the battery is used to power the electric machine, and can increase if the electric machine supplies power to the battery via regenerative braking. Constraints are placed on the vehicle such that the battery operates within a preferred operating window, defined between minimum and maximum state of charge thresholds. At least one controller is programmed to alter the preferred operating window of the battery in response to various vehicular activities, such as when the vehicle is towing another object, or when the vehicle weighs above a certain threshold due to contents within the vehicle, for example.

Load-based vehicle operating control

A vehicle power generation mode control method includes initiating a vehicle power generation mode request; determining whether at least one of the following conditions exists: high engine revolutions per minute is allowed; high voltage or amperage draw is allowed; current fuel level supports power generation mode; and carbon monoxide readings are within acceptable limits; denying requests for engagement of a vehicle transmission if at least one of the conditions exists; and allowing or commanding the vehicle power generation mode.

Vehicle power generation mode control method

A system and method for controlling a hybrid vehicle having an engine configured to automatically stop in response to an engine stop request and automatically start in response to an engine start request include selectively inhibiting an engine stop request based on an anticipated duration of an expected decreased driver power command state to reduce occurrence of successive automatic stops and automatic starts.

Predictive engine pull up and pull down in hybrid vehicle

A powertrain for a vehicle may include an engine and at least one controller. The controller may be programmed to, while the engine is off and during a generally constant accelerator pedal input, start the engine in response to an increase in relative acceleration of an object in front of the vehicle greater than a threshold.

Ein Verfahren zum Steuern eines Hybridfahrzeug, das einen Verbrennungsmotor aufweist, beinhaltet das automatische Stoppen des Verbrennungsmotors als Reaktion darauf, dass der Fahrzeugleistungsbedarf unter die aktuell verfugbare elektrische Leistung fallt und, als Reaktion auf das Aufnehmen eines Signals, das eine positive Steigung angibt, das automatische Starten des Verbrennungsmotors, wenn der Fahrzeugleistungsbedarf bei einem ersten Offset unter der aktuell verfugbaren elektrischen Leistung liegt, um eine Zeitverzogerung zum Starten des Verbrennungsmotors zu reduzieren und eine aktuell verfugbare Fahrzeugleistung zu erhohen, um das Fahrzeug eine Steigung hinauf zu bewegen. Ein Hybridfahrzeug enthalt einen Verbrennungsmotor, eine Elektromaschine und einen Controller. Der Controller ist dazu ausgelegt, Starten/Stoppen des Verbrennungsmotors als Reaktion auf eine erste Fahrerabforderung zu steuern, wenn er ein Signal aufnimmt, das angibt, dass ein Fahrbahnsteigungswinkel einen entsprechenden Schwellenwert uberschreitet, und andernfalls als Reaktion auf eine zweite Fahrerabforderung.
