Definitions
- the invention relates to a method for determining the range of a motor vehicle.
- the range is of particular interest in motor vehicles which comprise an electric drive, ie electric vehicles or so-called hybrid vehicles, because electric vehicles in particular only have a relatively short range at least at the present time;
- electrical energy must be provided to motor vehicles, typically in electro-chemical energy stores (batteries), and these can not be recharged as quickly as a fuel tank can be refilled.
- the present invention is equally applicable when the motor vehicle has only one internal combustion engine.
- a method for determining the range of an electric vehicle is known from DE 103 02 504 A1.
- vehicle, route and / or environmental information about the vehicle and a planned or current driving route are recorded and processed by a vehicle computer by means of suitable information recording devices.
- the processing includes an evaluation of a variably changing vehicle operation.
- This document also mentions as to whether the driver certain vehicle comfort functions such. B. would like to use an air conditioner. If the comfort functions desired by the driver attack the supply of electrical energy too much, he receives information in this regard from the vehicle computer. The aim is that he can reduce his comfort wishes to the degree necessary to achieve the goal.
- the object is achieved by a method having the features of patent claim 1.
- the measured ambient conditions but preferably the climate data obtained via weather data in the range of the route to be traveled and / or at least the temperature of at least one predetermined component of the motor vehicle are taken into account.
- the amount of energy to be consumed by at least one electrical consumer which is dependent on the at least one detected temperature variable, namely for producing and / or maintaining the operability of the motor vehicle, is taken into account in determining the range.
- another variable can be measured which detects the physical or chemical state of at least one component (eg the state of charge of a battery), provided that this quantity can be used to determine the extent to which energy can be produced and maintained.
- the invention is based on the recognition that obstacles which would prevent the motor vehicle from being put into operation or starting up occur at certain temperatures and do not occur or only to a lesser extent in others or that such obstacles are detected on measured values of a different size and / or weather data can be.
- the at least one electrical load also includes means for changing the temperature of an electrochemical energy store (the battery) to operate the electric drive.
- the invention is based on the recognition that the main batteries used for electric drives must have a predetermined temperature in order to provide sufficient energy for an electric drive can. They must therefore be preheated before starting the motor vehicle at low temperatures, cooled at high temperatures and also cooled during operation.
- the energy to be applied in this case is taken into account in determining the range in the context of the invention, so that the range is determined as precisely as possible; because of the o. g. Energy consumption is not inconsiderable at least at some temperatures.
- the predetermined component of the motor vehicle is preferably the battery itself.
- the at least one electrical consumer comprises a device for clearing a window pane of a fog (with moisture etc.) or a coating (with ice); For an icing of the window, for example, occurs only below a certain temperature limit.
- the humidity can be considered.
- the device may, for. B. have a hot air blower, simply heat by means of a heating wire, or with metal vapor coated and heated discs include.
- the invention is preferably used in a motor vehicle which comprises an electric drive.
- the energy to be applied for moving the motor vehicle is estimated as a function of the corresponding temperature variable during the determination of the range;
- the rolling resistance, the internal friction resistance (eg in the drive train) and also the air resistance of a motor vehicle depend on the temperature.
- the component in question whose temperature is being measured may be itself the predetermined component.
- the method according to the invention is carried out in an alternative before driving.
- the determination of the range is then used to inform the driver, whether he can perform a designated trip - with desired reserves.
- the range is typically determined by (or in) the motor vehicle itself and then transmitted wirelessly to a vehicle-external device (eg, an intelligent mobile radio telephone) carried by the driver, or an information center.
- the actual energy consumption is continuously determined, compared with the contents of the energy storage, the range calculation is constantly updated, and the vehicle driver or other vehicle occupant informed whether the predetermined destination is achievable with or without a predetermined measure especially in the case of an electric vehicle or a motor vehicle with hybrid drive the predetermined measure may consist in recharging a battery of the motor vehicle.
- a desired destination can be entered, and the navigation system can then determine the proposed route.
- the altitude, the rolling resistance of the road and other components are known, for. B. obstacles such as traffic lights and railroad crossings.
- the range it is also possible to take into account whether the driver has certain comfort requirements, eg. B. would like to put an air conditioner or a seat heating in operation. If the properties of the motor vehicle are known, then the consumption of energy can be estimated on the basis of an energy balance.
- the motor vehicle is not readily operable. For example, it may be that due to too low a temperature of a battery of the motor vehicle, if it is an electric vehicle, must first be preheated, or that it must be cooled at high temperatures, first or during the entire journey. Likewise, in conventional vehicles with internal combustion engine after a cold start additional energy for the heating of this engine - and to overcome the higher vehicle-specific resistances - are used in hot engine, additional energy for cooling may be necessary.
- the windshield and the other windows of a motor vehicle are icy or misted and must be heated, at least when driving and possibly during the entire journey. It may be necessary to use energy for air cleaning and temperature control systems for the vehicle interior. All of this can be calculated by the fact that the ambient conditions (such as temperature, humidity, solar radiation or pollution of the ambient air) are recorded and / or actually measured via generally available weather data or also via the temperature of a predetermined component of the motor vehicle, such , the battery, the An intelligent unit in the motor vehicle (data processing device) can then calculate on the basis of the measured values of corresponding sensors and / or the information about weather data, how driving resistances have to be considered and which electrical consumers for the production / Maintaining the operability of a motor vehicle must be activated.
- the ambient conditions such as temperature, humidity, solar radiation or pollution of the ambient air
- the energy to be consumed in this case is taken into account in the overall energy balance and thus in the determination of the range by an intelligent unit, preferably in the motor vehicle.
- an intelligent unit preferably in the motor vehicle.
- the temperature In terms of energy consumption - and thus also on the range of a vehicle - there is a dependency on certain parameters, such. B. the temperature. This dependence can be determined in the development of a new vehicle and by maps in databases, such. B. store in control units.
- the corresponding production vehicle can already have this optimized range calculation from day one.
- the amounts of energy are additionally detected in each case, which are needed beyond a normal operation beyond, this normal operation is defined, for. For example, by specifications, as they are set for a type test. These data can also be stored, for example, in control units and - under the same boundary conditions - again be used for an intelligent range calculation.
- the range is calculated very precisely.
- the determined range can be transmitted to the motor vehicle driver long before the journey starts to a mobile phone, another mobile device, or an information center (networked computer).
- an information center networked computer.
- corresponding updated range displays or instructions to the vehicle driver, to other occupants in the motor vehicle, or an information center can be made.
