Description

Consumption Instruction System for Vehicles {CONSUMPTION INDICATION SYSTEM FOR A VEHICLE}

The invention relates to at least one display for displaying consumption information, means for detecting a current energy consumption of a vehicle, a calculation unit for generating consumption information to be displayed on the display according to the detected energy consumption, and a connection with the calculation unit. A consumption indication system for a vehicle, in particular for a motor vehicle, comprising an integrated navigation system.

Further, the present invention comprises at least one display in which consumption information is displayed according to the energy consumption of the vehicle, and the data is exchanged with the navigation system of the vehicle, in particular the method of operating the consumption indication system of the vehicle as described above. It is about.

The consumption instruction system and the method of operation of the consumption instruction system are known in the prior art. Increasing environmental awareness and rising fuel prices have increased interest in the energy consumption of vehicles, especially fuel economy. Each driver's individual driving style can produce completely different results with regard to energy consumption at the same distance. In order to raise the driver's awareness of energy consumption, it is known to install a consumption instruction system in the vehicle which displays the consumption information to the driver in accordance with the detected energy consumption. It is known to direct the driver of the current energy consumption, in particular the current fuel economy, via the display of the consumption indication system. The calculating unit evaluates the data of the means for detecting the current energy consumption to generate corresponding consumption information. Such a consumption indication system is known, for example, from European patent application EP 1 018 449 A2. The known system displays the current moment consumption and average consumption simultaneously on the display. Further, it is known in the publication that a navigation system of a vehicle is connected into the consumption instruction system to display the fuel economy estimated for the distance to be traveled together with the current fuel economy. This makes it possible for the driver to adjust the driving mode on a case-by-case basis by comparing the current consumption with the estimated consumption.

The problem of the present invention is that the driver can know information on the distance-related energy consumption so that there is always a motivation to improve the energy consumption.

This object is achieved by a vehicle consumption instruction system according to claim 1 and a method of operating a vehicle consumption instruction system according to claim 10.

The consumption indication system according to the present invention has the advantage that, compared to the prior art, the driver can know the information on the distance-related energy consumption and always have the motivation to improve the energy consumption. It stores according to the invention at least one starting point-target point pair detected by the navigation system by the calculation unit of the consumption indication system and / or at least one consumption value respectively detected between the moved point and the starting point and the target point, If necessary, for example by the driver, this is achieved by displaying on the display. In the consumption instruction system according to the present invention, the consumption information related to the distance traveled may be displayed to the driver by considering the data of the navigation system. Thus, the driver can compare the consumption values of the traveled distance with each other. In particular, by comparing the consumption values of the distance that the driver has traveled several times with each other, it is possible to be motivated to adjust the driving characteristics or to improve the energy consumption. The calculating unit may store only the starting point and the target point of the distance together with the at least one associated consumption value. In addition, the calculation unit may store the actually traveled distance together with the at least one associated consumption value. The detected start point-target point pair and the moved distance are the driving start point where the vehicle was actually and the distance the driver traveled to that vehicle. Thus, in particular the distance already stored before the start of driving can be directed to the driver with at least one relevant consumption value, and the driver can select a suitable distance for navigation or a distance with the most desirable consumption value so far. In addition, the consumption value experienced by the driver at the end of the driving can be directed to the driver for comparison with at least one, preferably a plurality of stored consumption values with respect to the starting point-target point pair or the distance traveled. It is particularly desirable for a list with the best consumption values and the current consumption value to be displayed for comparison.

If at least the starting point-target point pair of the current distance coincides with the starting point-target point pair of the stored consumption value, it is preferred that at least one stored consumption value is displayed on the display of the consumption indication system together with the at least one current consumption value. The starting point-target point pair of stored consumption values is the starting point-target point pair to which the stored consumption value has been assigned or has been assigned by the calculation unit. By simultaneous display of the stored consumption value and the current consumption value, assigned to the same starting point-target point pair, the driver is explained how the current operating characteristic differs from the previous operating characteristic with regard to energy consumption in a simple manner. As a result, the driver is always motivated to achieve or reduce the consumption value previously experienced.

It is particularly preferred that at least one stored consumption value is displayed on the display along with the at least one current consumption value if the current distance moved or predetermined distance by the navigation system matches the stored distance assigned to the stored consumption value. On the basis of the data of the navigation system, if the calculating unit detects that the driver has traveled or intends to travel a distance already traveled, the consumption value stored at least so far with the current consumption value is indicated by the driver At each time point of the distance, the driving characteristics can be evaluated and optimized in relation to the previous driving characteristics.

Preferably the calculating unit calculates the theoretical consumption value according to the distance selected by the navigation system. In this case, the calculation unit calculates at least one theoretical consumption value with the selected, i.e. knowing distance to travel. This may be based on engine data or engine characteristic curves and optionally other data stored in the navigation system. It is used by the driver as an additional manual on its driving characteristics.

It is preferred that the lowest consumption values are selected from the stored consumption values and indicated with the current consumption values. If a number of consumption values have already been detected and stored for the starting point-target point pair and / or for a particular distance, since the driver has already traveled from the starting point several times to the target point, the lowest consumption values are preferably selected and together with the current consumption value. By being instructed, the driver is informed of the best mark thus far with respect to the consumption value to motivate them to have different consumption optimized driving characteristics.

As at least one consumption value, it is particularly preferred that the average consumption value and / or moment consumption value is detected or calculated. The average consumption value is a value representing the average consumption over the entire distance from the starting point to the target point or the current place. Of course, the partial-average consumption value can be detected or calculated and indicated. The moment consumption value is the actual consumption that was detected / detected at each point of the distance.

According to a preferred refinement of the invention, if the detected starting point-target point pair matches the stored starting point-target point pair, the navigation system selects the distance with the lowest consumption value stored. In particular, this was the case when the driver had already indicated that he wanted to take a travel optimized journey. The driver can dictate this, for example, via a navigation system or by selection of a consumption optimized driving stage.

Preferably, the calculation unit is assigned an input device, by which the driver of the vehicle can enter the name, which name together with the detected starting point-target point pair and / or the moved distance, in particular the date and And / or stored with time. Thus, at least one consumption value is assigned the name of the driver who has achieved this consumption value. Preferably the calculation unit indicates a table with, for example, 5 or 10 best consumption values, with each consumption value being further indicated with a date, time and / or driver name. The driver can have a table or top list (top 10) indicated until the end of the journey and know where the consumption value has been achieved or how the consumption value is compared to the consumption value already experienced. The input means may be input means provided to the navigation system or additional input means may be provided.

Preferably the consumption indication system is formed as a combination device. Usually, a combination device of a vehicle consists of a combination of a speedometer, a tank indicator, a coolant temperature indicator, a caution and the like, and a driving direction indicator, and optionally a speed sensor. In this case, the display of the consumption indication system is integrated into the driver combination device. The consumption indication system is connected via means of the vehicle CAN-bus with means provided for detection of consumption, such as speed and / or speed sensors and injection systems and / or navigation systems of internal combustion engines.

The method according to the present invention provides at least one starting point-target point pair detected by the navigation system and / or the moved distance and at least one consumption respectively detected between the starting point and the target point, as described above in particular with respect to the consumption indication system. The value is stored and indicated on the display if necessary. It is particularly preferred that at least one stored consumption value is displayed on the display together with at least one current consumption value if at least the starting point-target point pair of the currently moved distance matches the starting point-target point pair of the stored consumption value. In addition, if the distance that is currently moved or predetermined by the navigation system coincides with the stored distance, it is preferred that at least one stored consumption value is displayed on the display together with the at least one current consumption value. It is particularly preferable that the lowest consumption value is selected from the stored consumption values and is indicated with at least one current consumption value, thereby motivating the driver to configure its driving characteristics to be optimized for consumption. Preferably at least one moment consumption value and / or at least one average consumption value is detected or calculated as a consumption value. In particular, if the detected starting point-target point pair matches the stored starting point-target point pair, the navigation system selects the distance with the lowest consumption value stored.

The method according to the invention gives the driver the advantage of allowing the distance stored before the start of driving to be indicated with its consumption in order to select the distance and / or the most economical distance suitable for him. In addition, the driver can compare the current consumption value with the stored consumption value during driving, so that the driver can always be motivated to achieve a new consumption-best value or to further reduce the energy consumption.

According to the present invention, the driver can know the information about the distance-related energy consumption, thereby always being motivated to improve the energy consumption.

Hereinafter, the present invention will be described in detail with reference to the drawings.
1 is a schematic diagram of a consumption indication system;

1 schematically shows a consumption support system of a motor vehicle. The consumption instruction system comprises a screen or display 2 on which at least consumption information can be displayed to the driver of the vehicle. In addition, the consumption instruction system 1 includes a calculation unit 3, which determines the information to be displayed on the display 2. The calculating unit 3 is also connected with means 4 for detecting the current energy possession of the vehicle. The means 4 are in this case a unit 5 for detecting the current speed v of the motor vehicle. The unit 5 preferably comprises at least one speed sensor and / or a speed sensor. As another means 4, the engine control device 6 of the motor vehicle 1 is used. The engine control device 6 transmits data relating to the current energy consumption of the motor vehicle to the calculation unit 3. If the motor vehicle comprises a so-called hybrid drive device consisting of an internal combustion engine and at least one electric machine, the data can relate to the electric energy consumption and fuel consumption of the motor vehicle. However, for the sake of convenience, in the present embodiment, only an internal combustion engine is included as the engine, so that an automobile in which the engine control device 6 transmits data d of the fuel injection system of the internal combustion engine to the calculation unit 3 is assumed.

The calculation unit 3 first calculates the moment consumption value a and the average consumption value b by the consumption calculation device 7 from the data v, d related to the speed and the injection system. The moment consumption value represents the current fuel consumption of the vehicle, while the average consumption value b represents the average consumption of the vehicle since the start of the run or since another starting point selected by the driver.

The calculating unit 3 also comprises a device 8, to which the moment consumption value a and the average consumption value b are supplied. The device 8 determines which of these values and how the value should be displayed on the display 2. The device 8 can determine, for example, whether the moment consumption value a and the average consumption value b are displayed on the display 2 at the same time. The device 8 comprises a nonvolatile memory 9, in which the consumption values, ie the moment consumption value a and the average consumption value b, can be stored.

In addition, the consumption instruction system 1 is connected to the navigation system 10 of the automobile, so that the navigation system 10 forms a component of the consumption instruction system 1 in this case. As an alternative, the consumption instruction system 1 may be formed as a component of the navigation system 10. The calculation unit 3 and the display 2 are preferably a calculation unit or a display of a navigation system. The navigation system 10 detects a starting point and a target point and optionally detects a distance traveled by the driver between the starting point and the target point. The starting point-target point pair of the mileage and optionally the distance itself is transmitted to the device 8, which associates the data obtained by the navigation system 10 with the consumption data obtained by the consumption calculation device 7, At least one associated consumption value is assigned to the detected starting point-target point pair and / or the moved distance and stored in the memory 9 together with the starting point-target point pair and / or distance. If the calculating unit 3 detects whether the starting point-target point pair currently detected by the apparatus 8 corresponds to the already stored starting point-target point pair, the calculating unit is configured on the display 2 and the consumption value a actually detected. In addition to (b), one or more consumption values assigned to the starting point-target point pair, previously stored in the memory 9, are represented. Thus, the current consumption value and the previous consumption value are simultaneously instructed to the driver of the vehicle, so that the driver can directly compare the current driving characteristic with respect to the energy or fuel consumption with the previous driving characteristic and adjust or optimize as the case may be. Preferably the calculation unit 3 or the device 8 selects the lowest consumption values from the stored consumption values which have always been detected between the starting point and the target point of the starting point-target point pair. Preferably stored consumption data in which the moved distance matches the stored distance is indicated.

Preferably the communication between the navigation system 10 and the computing unit 3 or the device 8 is such that the device 8 matches the starting point-target point pair already stored with the starting point-target point pair required by the navigation system 10. If it is detected, the calculation unit 8 transmits the consumption value assigned to the stored starting point-target point pair to the navigation system 10, so that the navigation system 10 has the lowest consumption value stored based on the stored consumption value. Is made to select. This makes it possible for the driver to provide in advance the distance by the navigation system 10 which generates the lowest consumption value in the individual driving characteristics. As an alternative, the device 8 may select and transfer the distance with the lowest consumption value between the predetermined start point-target point pairs to the navigation system 10. Likewise on the display 2 or on the display of the navigation system 10 the lowest stored consumption values are indicated for each distance along with a number of distances selected between a given start-target point pair, thereby allowing the driver himself to It can be determined whether the distance is the best for the moment.

If the starting point-target point pair is driven by the driver several times, for example, the driver can always compare the current consumption with the stored consumption since the driver can always be directed with the lowest consumption value so far, in particular the lowest average consumption value. The driver always achieves a new consumption-best value and is motivated to lower its consumption or adjust its operating characteristics for lower consumption. The driver can cause the stored distance on the starting point-target point to be indicated with the corresponding stored consumption value and start selecting the appropriate or most economical distance before starting the journey.

In order to keep the memory need of the consumption support system 1 low, preferably only the lowest consumption value with respect to the starting point-target point pair and / or the moved distance is stored. In other words, if a new consumption value of the starting point-target point pair and / or distance, ie, a consumption value lower than the corresponding stored consumption value, is detected, then the already stored consumption value is replaced with the currently detected consumption value.

The consumption indication system may determine or use the consumption value of the starting point-target point pair regardless of the moved or given distance or according to the moved distance. The consumption instruction system 1 is preferably connected for data exchange with the means 4 and the navigation system 10 via a CAN bus not shown here. Preferably, the consumption indication system 1 is formed as a combination device or a combination device of a vehicle, so that, together with the consumption value and optionally navigation data, the speed, the amount of fuel remaining, the temperature of the coolant or the internal combustion engine, and in some cases It may include or form a back and / or speedometer and driving direction indicator.

The navigation system 10 may determine the starting and target points of travel and / or the distance traveled, preferably by GPS data, in particular whether or not the driver of the vehicle has activated or not the navigation system 10 for guiding the driver. Detect regardless. Once the driver has activated the navigation system 10 for guidance, it is preferred to him from different distances to achieve the goal and from the lowest consumption values detected so far or theoretically calculated consumption values, as described above. The selection of is displayed / indicated.
