Definitions
- the invention is based on a method or a device for determining the distance still travels in vehicles with the features of the preamble of the independent claims.
- a display is usually present, which informs the driver about the level of the fuel tank. In many cases, the driver is also shown which route he can probably cover by means of the remaining fuel. For this purpose, the driver is the value of
- an electric vehicle is known in which vehicle, driving distance and / or environmental information about the vehicle is detected and processed by a vehicle computer in order to determine the range of an electric vehicle. Subsequently, the remaining range of the electric vehicle is calculated from this information and / or the evaluation result and displayed in a display device. Disclosure of the invention
- the present invention is based on a method and / or a device for determining the still traversable travel distance in vehicles which have a plurality of drive modes.
- vehicles which are operated with different fuels, e.g. Gas vehicles. These vehicles are usually powered by gas.
- the gas stations are not as common as the usual gasoline / diesel gas stations.
- the use of these vehicles should not be limited only to those areas where gas stations are available. Therefore, in addition to the gas drive, these vehicles also have a second drive mode as the first drive mode.
- the internal combustion engine can be switched to gasoline operation. For this purpose, an additional gas tank is available. Thus, a nationwide use of the vehicle is guaranteed.
- Another characteristic of the two drive modes are hybrid vehicles which are driven by both an internal combustion engine and by means of an electric machine.
- the operation of the internal combustion engine with a fuel represents the one drive mode.
- the other drive mode is by the operation of the vehicle with the electric
- Machine represented by means of electrical energy from a battery storage.
- Fuel cells or mechanical energy sources, e.g. Flywheel mass storage are represented.
- the essence of the invention is that the failure of a drive mode is taken into account when determining the distance that can still be covered.
- the invention has the advantage that after recognizing an intended unavailability of a drive mode, the still traversable distance and still achievable destinations are determined directly and communicated to the driver. This allows the driver to remove the vehicle from danger zones and or to target destinations where the
- the vehicle can not be moved on its own.
- the vehicle may normally continue to be moved by itself. This is particularly advantageous when the vehicle is in an area of increased danger, e.g. Railroad crossing, intersection or expressway is located. In such cases, the vehicle can be moved out of the danger area on its own.
- the at least two drive modes of the vehicle are represented by operation with at least two of the fuels and / or energy forms - gaseous, liquid and / or solid fuel - mechanical and / or electrical energy.
- gaseous eg. Natural gas, hydrogen
- liquid for example: gasoline, (bio) diesel, (bio) - ethanol, vegetable oil
- solid fuels for example: coal, wood
- flywheel mass memories which, for example, represent the mechanical energy form as a drive mode for a vehicle.
- the fuels mentioned and / or the energy will each be made available by means of different energy sources. This is because the storage of different forms of energy has different requirements for the energy storage.
- the gaseous, liquid and solid fuels are stored in containers and by hollow body to the
- the electrical energy can be stored in batteries or supercapacitors or made available directly by means of fuel cells and fed by electric conductors to the electric drive.
- the mechanical energy of a flywheel mass accumulator is contained in the mechanical flywheel mass system and can be transmitted by means of a clutch to other mechanical systems, for example a vehicle drive train. Depending on the application, environmental and environmental conditions, the optimal combination of drive modes can be used.
- the distance still to be covered and / or the destinations still to be reached are calculated on the basis of the remaining energy with which the at least one available drive mode can be used, in particular taking into account further influencing variables.
- the more limited the distance that can still be covered the lower the range of accessible destinations. All the more important is the quality of the information, since alternative routes can not be covered anymore.
- vehicle data for example, temperature, voltage and battery state of charge of the drive system
- driver influence pedal position, driving behavior of the last time, evaluation of the
- Navigation data ambient conditions (temperature, topology of the environment, navigation data), vehicle influence parameters (load condition) and connected units (comfort consumers, ancillary units).
- the still available drive mode is the operation by means of electrical energy, in particular by means of an electric machine, and for the determination of the still legible distance and / or still achievable destinations a state of charge the energy source, in particular the state of charge of a battery storage, is taken into account.
- a state of charge the energy source in particular the state of charge of a battery storage
- the determined information is transmitted to a driver of the vehicle by means of a navigation device.
- a navigation device already existing in the vehicle navigation device for the acoustic, visual and / or haptic transmission of the information can be used.
- the destinations are provided by a driver of the vehicle or already available via electronic maps, in particular workshops, parking lots and nearest exits of expressways representing the destinations. If the driver himself enters his workshop destinations in the map, can be checked in case of unavailability, which of the workshops is still available. Otherwise, alternative workshops, parking lots and exits available to the driver can be displayed, which are stored in the electronic maps.
- a driver of the vehicle is additionally supported in response to a detected unavailability of at least one drive mode, in particular by instructions regarding the driving dynamics and / or the choice of the route, so that the achievable destinations still reliable with the remaining energy available for the at least one remaining drive mode.
- an electronic control system can capture the driving dynamics of the vehicle, inform the driver and or lead to a more ideal driving style. This can be done, for example, in such a way that the driver is informed that the accelerator pedal is pressed more or less strongly in order to avoid strong accelerations with correspondingly high energy consumption.
- Another possibility is, for example, an ad that indicates that a Gear change is possible with which the average energy consumption can be reduced.
- the method according to the invention can be carried out after recognition of the unavailability of a drive unit. Since the situation in which the vehicle is constantly changing, also the calculated still Anlagenlegbaren change
- Figure 1 is a device for determining the distance still travels and / or still achievable destinations in vehicles with at least two
- FIG. 2 shows a method for determining the still traversable distance and / or still achievable destinations in vehicles with at least two
- FIG. 1 shows a device for determining the distance that can still be covered and / or destinations that can still be reached in vehicles with at least two drive modes. To the drive train (106) are two
- Driving machines an internal combustion engine (102) with a fuel tank (103) and an electrical machine (104) with a battery storage (105), flanged.
- a drive machine together with their respective energy storage devices each represent a drive mode.
- One Control unit (101) monitors the two drive modes for their availability and the level or state of charge of the associated energy storage. The determination of the still legible distance and / or still achievable destinations is also carried out by the control unit (101).
- FIG. 2 shows a method for determining the still traversable distance and / or still achievable destinations in vehicles with at least two drive modes.
- the first method step (201) it is detected that a drive mode is no longer available. This may be because coupling to the powertrain is not possible, that a prime mover has failed, that the fuel is no longer available for a drive mode, or that another condition has occurred that makes it impossible to use a drive mode.
- the second method step (202) it is detected what amount of energy is still available with which the at least one available drive mode can be used. For this are appropriate
- the still traversable distance and / or the still achievable destinations are determined with the remaining at least one drive mode. This determination takes into account that a drive mode has failed. Thus, only the legible distance that can be traveled with the remaining drive mode (s) is relevant. Accordingly, the destinations to be reached also reduce to those that can be achieved with the remaining drive mode (s). As mentioned above, the quality of the determined traversable distance and or destinations is critically dependent on which and how much additional information is used for the calculation.
- the steps mentioned can be cyclically repeated and processed.
