Description

Vehicle weight display

The present invention relates to a weight display device for a vehicle, and more particularly, a weight display for a vehicle that can reduce fuel consumption of a vehicle by detecting a weight of the vehicle and recognizing the driver when the overweight is detected, thereby removing unnecessary baggage. Relates to a device.

One of the most important things about driving a car is the driving resistance it receives when it runs, and the other is about fuel economy.

The total running resistance determines the driving force transmitted from the engine to the wheels. From the relationship between running resistance, engine power, and power train efficiency, the driving performance, ie maximum speed, climbing capacity and acceleration capacity, are determined.

On the other hand, the fuel consumption rate of the car varies a lot depending on the use of the car, the displacement, the load loading condition, the driving conditions, the running speed. According to KSR 1008, the measurement is performed by driving round-trip driving at a fixed speed on a vehicle with two people riding on an empty car on a flat, straight road. The test fuel shall be equivalent to that specified in KSM 2612.

As is well known, the fuel consumption rate can be calculated from the formula (100 * consumption fuel during test) / (fuel density * test distance) ℓ / 100km.

The fuel economy of a vehicle is determined by the engine displacement, the weight and structure of the vehicle, but it is also influenced by the driver's driving habits.

In particular, if the weight of the vehicle is larger than the proper weight by the loaded baggage, the driver may not immediately recognize that the fuel consumption is increased.

In other words, most drivers typically recognize that fuel consumption increases when the vehicle speed is too high.

However, when habitually carrying unnecessary luggage in the rear seat or trunk of the vehicle, the weight of the vehicle is greater than the appropriate weight by the driver's habit, which acts as a main cause of increasing fuel economy of the vehicle.

Conventionally, since there is no special device for recognizing the driver when the vehicle is driven by a heavy load or an excessive number of passengers, and the vehicle is driven at an appropriate weight or more, it is possible to reduce the life of the vehicle and to fix a large accident due to the fixing of the vehicle. There is a problem that causes.

The present invention has been made to solve the above-described problems, by configuring a display device capable of recognizing a signal detected from the weight sensors and weight sensors mounted on the seat and trunk bottom of the vehicle to the driver The driver's weight status and overweight location can be immediately recognized by the driver to remove unnecessary baggage that is overweight in the vehicle, or the excessive number of passengers can be unloaded to prevent fuel waste and extend the life of the vehicle. It is an object of the present invention to provide a vehicle weight display device.

The present invention is configured as follows to achieve the above object. That is, a plurality of weight detection unit mounted on the seat of the vehicle and the floor of the trunk to detect the weight and output the corresponding data; Arithmetic processing unit for arithmetic processing to add each data output from the weight sensing unit; And a weight display unit that displays numerical values obtained by digitizing data output through the calculation processing unit.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention in detail.

1 is a view showing an instrument panel equipped with a vehicle weight display device according to the present invention.

As shown in FIG. 1, the instrument panel 10 of the vehicle is equipped with an LCD and a digital indicator 40 as a vehicle weight display device, and the vehicle weight display device displays the current vehicle weight and the reference weight together. do.

In addition, the vehicle weight display device may display a corresponding position where the overweight of the vehicle is detected.

2 is a view showing a vehicle weight display device according to an embodiment of the present invention.

The present invention, as shown in Figure 2 is mounted on the seat and the trunk bottom of the vehicle weight detection unit 12 having a first and fourth weight detection sensors for detecting the weight and output the corresponding data, and the weight An arithmetic processing unit 14 for performing arithmetic processing to add each data output from the sensing unit 12, and comparing each data output from the weight sensing unit 12 with data according to a reference voltage signal and outputting the difference A comparator 16 having a first comparator and a fourth comparator, and a digitized value of the data output through the arithmetic processing unit 14, and the vehicle according to the output signal output through the comparator 16. It is composed of a weight display unit 20 consisting of an LCD and a digital display to display the overweight position of the display and the set value for the appropriate weight of the vehicle.

The operation process of the present invention configured as described above will be described with reference to FIGS. 1 and 2.

First, the weight detector 12 outputs respective data corresponding to the weight detected through the seats (driver's seat, passenger seat, rear seat) of the vehicle and the first and fourth weight sensors mounted on the trunk floor.

The operation processor 14 adds all the data output from each weight sensor from the weight sensor 12.

Then, the weight display unit 20 mounted on the instrument panel 10 displays the data value output through the arithmetic processing unit 14 as a digitized value to indicate the weight of the current vehicle and set a value for the proper weight of the vehicle. Is displayed to indicate the weight of the reference vehicle together.

In addition, although the present invention is not illustrated in FIG. 1, the weight display unit 20 may indicate an overweight position in the vehicle.

That is, when the weight data of the vehicle is output through the weight sensor 12, the comparator 16 may include a first weight voltage V _G1 corresponding to each data output from the weight sensor 12, and a second weight data. The second weight voltage V _G2 , the third weight voltage V _G3 , and the fourth weight voltage V _G4 are input to the non-inverting terminal (+), and the reference voltage Vref is input to the inverting terminal (-). After comparing the two voltages through the first and fourth comparators and outputs the voltage difference, respectively.

The weight display unit 20 displays the overweight position of the vehicle in response to the output signal output through the comparison unit 16.

For example, when the first weight sensor of the weight sensor 12 is mounted in the trunk and there is a lot of baggage in only the trunk, the comparator 16 receives the first weight sensor from the first weight sensor. The detected first weight voltage V _G1 is compared with the reference voltage Vref and a high level output signal corresponding to the overweight is applied to the weight display unit 20.

At this time, the comparator 16 applies a low level output signal corresponding to the reference weight or less to the weight display unit 20 through the second and fourth comparators except the first comparator.

Then, the weight display unit 20 receives signals applied from the comparator 16 and indicates only a trunk mark of the vehicle displayed on the screen of the LCD 40 to indicate that the driver is being overweight on the trunk. Make it aware.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.

Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.

As described above, according to the present invention, when a user loads a lot of luggage and rides a passenger, the weight display unit mounted on the instrument panel displays the reference weight of the economical vehicle together with the current vehicle weight so that the driver sees this and how much the vehicle is currently. Think about whether you are under heavy load.

Therefore, the driver can remove unnecessary luggage in the vehicle, thereby lowering the fuel economy of the vehicle and at the same time saving energy.
