Definitions
- the present invention relates to a method and a system for displaying a warning message to warn of insufficient drive power available for use in an electric vehicle.
- the invention also relates to a motor vehicle with a generic system.
- the driving performance of an electric vehicle depends largely on the cell chemistry of the floch-volt batteries used and the temperature. A distinction is made here with regard to the performance of floch-voltage batteries in peak and continuous output, which can be massively different at low temperatures and / or with a low energy content. This battery behavior can be relevant to safety, for example if a driver drives onto a motorway at low temperatures with a low battery. For this reason, it makes sense to warn a driver of such situations accordingly.
- DE 10 2013 220 015 A1 relates to a system and a method for estimating the available capacity of a battery element in a vehicle.
- US 2017/0254858 A1 relates to a system and a method for monitoring and controlling the state of a battery.
- the object of the invention to at least partially remedy the above-described disadvantages of a method or a system for displaying a warning message to warn of insufficient drive power for use in an electric vehicle; in particular, the object of the present invention is to to provide a method and a system for warning of insufficiently available drive power, which guarantee an effective and at the same time user-friendly warning of insufficiently available drive power in a particularly simple and inexpensive manner.
- the subject method for displaying a warning message can preferably be used in at least partially electrically operated vehicles, such as hybrid vehicles, or in fully electrically operated vehicles.
- the method in question can also be used in commercial vehicles, ships or flying objects.
- the method according to the invention for displaying a warning message to warn of insufficient drive power for use in an electric vehicle comprises the steps of acquiring measured values to determine a current power of an energy store of the electric vehicle by means of a detection unit, determining a current peak power and / or Continuous power of the energy store based on the recorded measured values by means of a processing unit, comparing the current peak power and / or continuous power with a threshold value of the peak power and / or continuous power by means of the processing unit and displaying a warning message when the threshold value of the peak power and / or continuous power is not reached by means of a Display means, the method not being started until an attempt is made to establish readiness to drive.
- a peak power is understood to mean, in particular, a maximum achievable instantaneous power which can preferably be provided for a short time interval of 1 to 30 seconds.
- continuous output is understood to mean, in particular, a permanently maximum achievable output, which is preferably a significantly longer time interval from minutes to hours can be provided.
- a threshold value is also understood to be a specified or specifiable value of a peak and continuous power, which can be specified, for example, in such a way that a vehicle in which the method in question is still able to travel a certain minimum distance, for example at least maneuvering can or can reach a charging station.
- an attempt to establish readiness to drive is understood in particular to mean a process in which a driving process is to be initiated. Such a process therefore preferably differs from merely starting a vehicle in which a vehicle is not intended to move.
- the establishment of readiness to drive should preferably be the criterion or the necessary condition that the method according to the invention is carried out at all.
- An objective determination of a current peak power and / or continuous power of the energy store on the basis of the recorded measured values by means of a processing unit can preferably include the preliminary processing of the recorded measured values. This can include, for example, a mere averaging or weighting of individual measured values, but it can also take the form of complex data evaluation methods.
- the objectively provided warning of insufficient drive power in particular due to the fact that the method is only started when an attempt is made to establish driving readiness, guarantees a particularly user-friendly warning of insufficient drive power in which the driver is not disturbed by warning messages during a charging process or simply starting the engine without wanting to initiate a driving process.
- the steps provided for determining an insufficiently available drive power it is also checked in a particularly reliable manner whether a driving process can still be carried out or not, so that a warning is only issued in this way if necessary.
- the acquisition of measured values to determine a current power of an energy store is the acquisition of a current voltage and / or a current current and / or a current Temperature and / or a current state of charge and / or a current component temperature and / or a current energy content.
- additional parameters such as the age of the energy store or the like can also be taken into account.
- individual parameters such as the current voltage and / or the current current, can also be determined in principle, whereas other parameters, how the current temperature or the like can only be determined when necessary, for example when a certain threshold value is reached.
- the method is at least partially carried out regularly during vehicle operation, the method preferably being carried out in fixed and / or definable periodic sections so that not only a warning message is displayed at the start, but also during the operation of a vehicle, provided that the correspondingly defined conditions, in particular falling below a peak and / or continuous power below a threshold value, are met.
- the fixed and / or definable periodic segments can be time segments, for example 500 ms or 5 minutes or the like, or also length segments of a covered length of, for example, 5 km, 10 km or the like.
- the warning message is in the form of a visual and / or acoustic signal.
- a visual warning message can take the form of a warning symbol or a warning text, for example.
- other signal forms such as vibratory signals or the like, can also be used.
- a number of warning forms such as a visual, acoustic and vibratory warning, can be combined with one another.
- an advance warning if the value falls below a fixed or definable multiple of the threshold value takes place, the multiple preferably being at least 1.25 times the threshold value.
- the type of advance warning differs from the warning message.
- the advance warning message in the form of another symbol, a different color, a different intensity or the like.
- an advance warning message is formed in the form of a yellow symbol and the subsequent warning message in the form of a red symbol, or the advance warning message has a smaller size than the warning message.
- the threshold value can be set individually, preferably determined as a function of an achievable machine speed.
- the achievable machine speed can in particular be in the form of an electric machine speed to be defined.
- the threshold value can advantageously also be touched at a maximum achievable speed of, for example, 15 km / h or the like.
- the threshold value can also be adapted to a maximum distance that can be covered, for example 500 m or several kilometers or the like, so that after the warning it is still possible to reach a charging station or at least to park the vehicle at a selected location.
- an adaptation to a maximum incline or the like of, for example, 5% that can be mastered can be provided.
- the output of a warning message depends on additional factors, such as, for example, falling below a previously defined electric machine speed or the like.
- a warning message can only be issued if, in addition to falling below a peak power and / or a continuous power, a definable threshold of an electric machine speed of, for example, 4000 min 1 (corresponding to approximately 50 km / h) is undershot.
- a proposed solution is generated during or after a warning message is displayed, the proposed solution preferably being a proposal for generation a higher drive power.
- the proposed solution can in this case, in particular, be suggestions for adapting a current energy consumption or also include proposals to adapt the operation of secondary consumers.
- a proposed solution can also include an adaptation of the operation from a first operating mode to a second operating mode.
- more than two operating modes can be provided.
- the invention also relates to a system for displaying a warning message to warn of insufficient drive power available for use in an electric vehicle.
- the system comprises a detection unit for acquiring measured values to determine a current power of an energy store of the electric vehicle, a processing unit for determining a current peak power and / or continuous power of the energy store on the basis of the recorded measured values and for comparing the current peak power and / or continuous power with a threshold value of the peak power and / or continuous power and a display means for displaying a warning message when the threshold value of the peak power and / or continuous power is not reached.
- the objective detection unit can preferably be integrated into the energy store or be arranged on it.
- the detection unit can preferably have a sensor unit or sensors for recording the measured values for determining the current power of an energy store.
- the sensors can be arranged directly on the system or, for example, also remotely from the system.
- the processing unit is in the form of a motor control device.
- the engine control unit is coupled to the energy store anyway and is therefore already arranged in the vicinity of the energy store, so that simple and uncomplicated data transmission is possible.
- the display means is in the form of an instrument display and / or an instrument cluster and / or a head-up display.
- An embodiment of the display element in question in the form of a capacitive display or the like arranged remotely from the steering wheel is also conceivable.
- a particularly effective warning it is also conceivable that several of the above-mentioned display forms are used and thus several display means are used simultaneously within a vehicle.
- the invention also relates to a motor vehicle comprising a system described above for displaying a warning message to warn of insufficient drive power available.
- FIG. 1 shows a schematic representation of the individual steps of a method according to the invention for displaying a warning message to warn of insufficient drive power available for use in an electric vehicle

As part of a particularly effective warning, several warning forms can also be combined with one another.
- the threshold value of the peak power and / or continuous power which is compared with the current peak power and / or continuous power in accordance with step 36, can advantageously be individually adjustable and, for example, can be set as a function of the maximum achievable machine speed or the like. In the context of an estimate of the drive power that is still available as precisely as possible, it is also conceivable that the expected consumption of secondary consumers is taken into account when determining the threshold value.
