Definitions
- the invention relates to a method for determining an aging state of a
- Fuel in a motor vehicle in particular a hydrocarbon compounds contained fuel.
- the method finds particular application in motor vehicles with at least two mutually different drives, eg. B. with a
- Internal combustion engine and an electric drive or with at least two independent energy storage, eg. B. a fuel tank and a battery, so z. B. in hybrid electric vehicles, or z.
- a fuel tank and a gas tank e.g. B. a fuel tank and a battery.
- Hybrid electric vehicles can be driven depending on the selected type of drive (drive the motor vehicle via the electric drive or via the internal combustion engine) with or without the use of fuel.
- drive the motor vehicle via the electric drive or via the internal combustion engine with or without the use of fuel.
- Motor vehicle can cause the motor vehicle for a longer period without the consumption of fuel, namely, for. B. purely electric, is operated. Under these circumstances, it is possible for a fuel stored in the motor vehicle to become old and to deteriorate
- powered motor vehicles for example bivalent gas and liquid fuel vehicles.
- Aging condition of the fuel known, which is usually used on the measurements of a tank level sensor. From a change in the tank level is thereby closed on a refilling of fuel. On the basis of the tank levels before and after the refueling process weighting factors are then derived, so that an aging state of the fuel mixture now contained in the fuel tank (from older and younger fuel) can be determined.
- a method is z. B. from WO 2009/128355 A1.
- the known methods for determining the aging board are sometimes complex in terms of apparatus and / or too inaccurate.
- an alternative method for determining an aging state is to be proposed, which preferably allows a technically simple, possibly retrofittable and / or as accurate as possible determination of the state of aging.
- a method for determining a state of aging of a fuel, in particular a liquid fuel, in a motor vehicle is proposed, wherein the state of aging is determined on the basis of a residence time of an amount of fuel in the motor vehicle, in particular in a hybrid motor vehicle having an internal combustion engine as one of the plurality of drives ,
- the method comprises at least the following steps: a) determining a maximum amount (a volume [liter] or a mass [kilogram]) of fuel that can be stored in a given fuel tank of the motor vehicle;
- the residence time (at least or exactly) corresponds to a period in which a
- the method is preferably carried out in the order given here, it being possible for the steps to be carried out, at least partially, also temporally parallel and / or immediately afterwards. It is possible that the steps (individually, grouped or in total) are repeated become.
- the method is preferably carried out in the operational state of the motor vehicle (automatically).
- a maximum amount can be determined which can be stored at most in the fuel tank of the motor vehicle.
- the fuel tank has as part of the motor vehicle on a fixed, and thus predetermined capacity, which is taken into account. If necessary, the capacity can be changed and / or specified.
- step b) the fuel consumption of the motor vehicle can be determined. This can be calculated in particular via the injection times (and / or injection rates) of the fuel. The injection times are controlled by the control of the injection valves
- a first group of embodiments may be injectors for injecting fuel into a suction pipe of the
- DI injection Internal combustion engine
- Control unit of the internal combustion engine before and can be used for the present method In determining the fuel consumption, the following factors may be considered in particular: geometry of the injection nozzle, pressure of the fuel, properties of the fuel, etc.
- the residence time of the fuel stored in the fuel tank can be determined.
- a first (predetermined or predeterminable) proportion of the maximum amount of fuel can be set.
- This proportion can z. B. amount to 100% of the maximum amount.
- the proportion is at least 80% of the maximum amount, preferably at least 90%.
- the proportion is at most 98%, preferably at most 95% of the maximum amount.
- This proportion may correspond to the usual amount of fuel that can be supplied to the motor vehicle in a refueling process. It is preferable to assume that this is the amount of fuel that corresponds to the maximum amount less a reserve amount.
- the reserve quantity is the amount of fuel present in the fuel tank, in which a
- step c) Reserve indicator for the user of the motor vehicle is activated. In step c), therefore, an assumption is made for the amount of fuel contained in the fuel tank. This amount corresponds to a (percentage) proportion of the maximum amount of fuel.
- the residence time of the fuel stored in the fuel tank determined in step c) can thus correspond approximately to a period in which a charge (the amount of fuel which is usually supplied to the motor vehicle as part of a refueling operation) of the fuel tank is consumed via the internal combustion engine.
- step c) The lower the consumption of fuel, the more the residence time determined in step c) is extended.
- the aging state of the fuel can be determined on the basis of the residence time.
- Determining the residence time according to step c) can be done exclusively on the basis of the cumulative injection times. In particular, refueling operations are therefore not detected and tank levels are not determined. Preferably, only the tank levels are not determined.
- the residence time of the fuel stored in the fuel tank can (automatically or possibly in feedback with a sensor system for detecting a refueling operation) to a Output value are reset when the predetermined proportion of the maximum amount of fuel is consumed.
- a (previously known or current) fuel quality of the stored fuel can be taken into account.
- the fuel quality is at least through
- a direct specification of fuel quality e.g. determined by coding the control unit for a certain fuel quality depending on the target market of the vehicle.
- the fuel quality includes in particular the type of fuel (diesel / biodiesel / gasoline, possibly the octane number or cetane number, possibly the proportion of ethanol and other types of alcohol) and preferably also the proportion z.
- type of fuel diesel / biodiesel / gasoline, possibly the octane number or cetane number, possibly the proportion of ethanol and other types of alcohol
- proportion z preferably also the proportion z.
- the fuel quality can be determined in particular by known fuel quality sensors. Such a fuel quality sensor may, for. B. are arranged in the vehicle. Alternatively or additionally, the fuel quality in a refueling operation can be transmitted from a refueling device (external to the motor vehicle) to the motor vehicle.
- Just the transmission of such a first information can be used to the residence time z. B. to reset to a (customized) output value.
- a quantity of fuel supplied with the refueling process can preferably be taken into account.
- the limit value of the aging state represents a limit from which (promptly) a (negative) influence on the vehicle function can no longer be reliably ruled out.
- a safety period (possibly depending on the quantity of fuel available in the fuel tank) is taken into account, so that appropriate measures are not initiated until the limit value has been reached.
- This forwarded to the user (driver) of the vehicle second information can, for. B. be a display and / or an audible warning to the user, after which z. B. visit a workshop or to use the internal combustion engine exclusively with the aging form of energy.
- the internal combustion engine ie no (sole) use of the alternative drive
- the consumption of the (aging) fuel can be accelerated, so that, considered in terms of aging state critical amount of fuel is consumed quickly.
- Internal combustion engine which consumes a fuel for driving the motor vehicle or for generating electrical energy, as well as an alternative drive for the motor vehicle; wherein the internal combustion engine is operated in response to an aging condition determined by the newly proposed method.
