The present invention relates to a method of determining at least one area (ZON) of a road network reachable by a vehicle driving on the road network. The method is based on the use of a dynamic model (MOD) of the vehicle depending on the vehicle speed and acceleration, the construction of a line graph (GA) and a shortest path algorithm (ALG).

A vehicle control system may include a power generator, a storage battery, a running electric motor, a determiner configured to determine an area toward which a vehicle occupant of the vehicle has a line of vision directed; a deriver configured to derive an index based on a frequency at which the vehicle occupant has the line of vision directed toward a specific area on the basis of a determination result; and a controller configured to operate the power generator in a case in which an amount of power of the storage battery is equal to or smaller than a threshold and operate the power generator regardless of the threshold of the amount of power of the storage battery in a case in which the index derived is equal to or higher than a predetermined degree.

An apparatus for displaying a distance to empty of a vehicle includes a controller configured to: estimate a mass of the vehicle, which increases or decreases while the vehicle is running; to calculate a driving energy consumption using a past-learned energy consumption based on a mass level corresponding to the increase or decrease in mass of the vehicle while the vehicle is running, and a current energy consumption of the vehicle; to calculate the distance to empty of the vehicle based on the driving energy consumption; to determine whether to update the distance to empty displayed on a display based on the mass level while the vehicle is running; and to update display information on the display based on the distance to empty.

The invention relates to a vehicle, in particular a motor vehicle, having reproduction means for displaying at least one current parameter of the vehicle, wherein the reproduction means are configured to represent the current parameter value on the reproduction means in the form of numbers or numerical words, wherein there are provided allocation means which are configured to allocate to the number or numerical word, on the basis of the value of the number or numerical word, the size of the number or numerical word and/or at least one parameter of the number or numerical word relating to the color and/or of the background thereof, and wherein the reproduction means are configured to represent the number or numerical word on the reproduction means with the allocated size and/or the color parameter.

An electric propulsion system includes a rotary electric machine having an output member, a rechargeable energy storage system (RESS) connected to the electric machine, a user interface device, and a controller. The RESS includes multiple battery modules and a switching circuit, the latter being configured, in response to electronic switching control signals, to connect the battery modules in a parallel-connected configuration or a series-connected configuration, as a selected battery configuration. The user interface device receives an operator-requested drive mode request as an electrical signal indicative of a desired drive mode of the electric propulsion system. The controller, which is programmed with mode-specific electrical loss information associated with the desired drive mode, establishes the selected battery configuration in response to the drive mode request, and presents a drive mode recommendation via the user interface device when the loss information associated with the desired drive mode exceeds a calibrated loss threshold.

An image display device includes an acquisition unit that acquires two or more types of information, a detection unit that detects at least one of an acceleration, an orientation, and an angular velocity of the image display device, an image change section that determines a state of the image display device on the basis of a detection result of the detection unit, switches information, which is to be selected from the two or more types of information acquired by the acquisition unit, in accordance with the determined state of the image display device, and generates display data based on the switched information, and a display unit that displays the display data.

A vehicle includes a battery that is mounted as a power source in the vehicle and an instrument panel that displays, to a user of the vehicle, an index (a capacity retention ratio Q or an electric vehicle (EV) travelable distance) indicating a larger value as deterioration of the battery progresses less. The instrument panel displays a maximum value of the index until a predetermined condition has been satisfied.

A display device includes: a display unit configured to display an index corresponding to a deterioration state of a secondary battery and an EV travelable distance; and a control unit configured to control display of the display unit such that a first decreasing amount by which the EV travelable distance displayed on the display unit decreases with the elapse of time until a predetermined condition has been satisfied is less than a second decreasing amount by which the EV travelable distance displayed on the display unit decreases with the elapse of time after the predetermined condition has been satisfied.

A display device includes: a display unit configured to display a degradation level of a secondary battery; and a controller configured to calculate the degradation level from measurement data of the secondary battery in every predetermined period and to control the display unit so as to display the degradation level. The controller is configured to, when a first degradation level indicating a newly calculated degradation level is lower than a second degradation level indicating a previously calculated degradation level, correct the first degradation level to a value equal to or higher than the second degradation level and to control the display unit so as to display the corrected degradation level.

A method is used to control a fuel level gauge of a vehicle system and includes: monitoring, via an engine controller, a fuel economy of the vehicle system; comparing, via the engine controller, the fuel economy with a predetermined fuel economy threshold to determine whether the fuel economy is less than the predetermined fuel economy threshold; adjusting, via the engine controller, a sensitivity of a display filter in response to determining that the fuel economy is less than the predetermined fuel economy threshold for a predetermined amount of time in order to maximize an accuracy of the fuel level gauge, wherein the display filter smoothes an unfiltered fuel level signal received from a fuel level sensor of the vehicle system, thereby generating a filtered fuel level signal; and controlling, via an instrument panel controller, the fuel level gauge of the vehicle system.
