Abstract:
In the case that a plug-in hybrid electric vehicle 10 runs using a motive power of electric motor 25 and an internal-combustion engine 27, a HV-ECU 60 prohibits that the clutch Plate 42, 43 becomes a connected state when a HV-ECU 60 determines a remaining fuel amount in the fuel tank 35 is less than or equal to a predetermined amount M based on information obtained from the fuel gauge 38.
Abstract:
Die vorliegende Erfindung betrifft ein Energiemanagementverfahren für ein Fahrzeug (1), das einen Energiespeicher (2) und mehrere Verbraucher (4) umfasst, bei dem der Energievorrat im Energiespeicher (2) erfasst und eine prognostizierte Ist-Reichweite des Fahrzeugs (1) berechnet wird, ein graphisches Objekt (10) erzeugt und angezeigt wird, welches die prognostizierte Ist-Reichweite visualisiert, eine Nutzereingabe erfasst wird, mit welcher eine Soll-Reichweite dadurch eingestellt wird, dass mittels einer Eingabeeinrichtung (8) das graphische Objekt (10) verändert wird, nach der Einstellung der Soll-Reichweite aus der Differenz der Soll-Reichweite und der prognostizierten Ist-Reichweite berechnet wird, mittels welcher Zustandsänderungen zumindest einer Teilmenge der Verbraucher (4) die Soll-Reichweite erzielbar ist, und die berechneten Zustandsänderungen als Vorschlag ausgegeben werden. Des Weiteren betrifft die Erfindung eine Energiemanagementvorrichtung zum Ausführen dieses Energiemanagementverfahrens.
Abstract:
The invention relates to a method for distributing energy in an electric vehicle comprising at least one electric energy store and at least one conditioning module, which can be used to generate electric energy from fuel, as energy sources, wherein driving-related information, or information about a state of the electric vehicle, is recorded before driving, or when beginning to drive, the electric vehicle and, while driving, energy is distributed in the vehicle on the basis of the information.
Abstract:
The invention relates to a method and a device for determining the distance which can still be travelled and/or destinations which can still be reached in vehicles having at least two drive modes. The core of the invention is that the distance which can still be travelled and/or destinations which can still be reached are determined as a function of the detection of the unavailability of a drive mode.
Abstract:
A control device is provided for a hybrid vehicle power transmitting apparatus wherein when a fuel type supplied to an engine is altered, a drop in startability of the engine resulting from alteration on the fuel type is suppressed. Fuel-type determining means determines the fuel type for use in operating the engine, based on which a reactive control representing a control of reactive control of a second electric motor counteracting rotational resistance of the engine during engine startup, is altered. Accordingly, second-motor torque (reactive torque) for increasing an engine rotation speed during engine startup is adjusted depending on the fuel type, thereby increasing a temperature of fuel compressed and expanded in the engine, to a level available to initiate an ignition. This prevents the alteration of the fuel type from causing degradation in startability of the engine when the fuel type supplied to the engine is altered.
Abstract:
In a hybrid vehicle with fuel cells (60) and an engine (10) mounted thereon as energy output sources, the technique of the present invention adequately changes a working energy output source according to a driving state of the hybrid vehicle. The hybrid vehicle has the engine (10) and a motor (20), both enabling power to be output to an axle (17). The hybrid vehicle also has fuel cells (60) as a main electric power supply for driving the motor (20). The technique of the present invention changes the working energy output source between the fuel cells (20) and the engine (10), in order to reduce the output of the fuel cells (20) with consumption of a fuel for the fuel cells (20). With a decrease in remaining quantity of the fuel, the technique narrows a specific driving range, in which the motor (20) is used as the power source. The technique also causes the engine (10) to drive the motor (20) as a generator and charges a battery (50) not with electric power of the fuel cells (60) but with electric power generated by the motor (20). This arrangement effectively prevents the fuel for the fuel cells (60) from being excessively consumed in one driving mode. The fuel cells (60) can thus be used preferentially in a specific driving state of the hybrid vehicle where the fuel cells (60) have a high efficiency.
Abstract:
A remaining fuel Z is calculated by subtracting a fuel injection amount J supplied to an engine 14 from stored fuel F measured by a fuel meter 12. A fuel economy Fm is calculated by dividing a running distance M of a vehicle by a fuel injection amount J. A cruising distance K is calculated by multiplying the remaining fuel Z and the fuel economy Fm.
Abstract:
The invention relates to a display unit for displaying at least one remaining range in a motor vehicle in accordance with the remaining energy supply in at least one drive system (e.g. the tank fill level in a vehicle driven by a combustion engine and/or the state of charge of the high-voltage battery in a vehicle driven by an electric motor); the display of the remaining range can be hidden even when there is a remaining energy supply if at least one defined operating condition is met. Preferably, a defined operating condition allows the conclusion that a unit of the drive system is at least temporarily unavailable.
Abstract:
Technologies for assisting vehicles with changing road conditions includes vehicle assistance data based on crowd-sourced road data received from a plurality of vehicles and/or infrastructure sensors. The crowd-sourced road data may be associated with a particular section of roadway and may be used to various characteristics of the roadway such as grade, surface, hazardous conditions, and so forth. The vehicle assistance data may be provided to an in-vehicle computing device to assist or facilitate traversal of the roadway.
Abstract:
An HV-ECU executes refresh-discharging of a battery before the battery is charged from a commercial power source using an AC/DC converter (S 110). After the battery is refresh-discharged (S150), the HV-ECU outputs a control signal to the AC/DC converter such that the battery is charged from the commercial power source by the drive of the AC/DC converter (S 170).
