DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measurement result of a deviation indicating the degree of deviation of a load applied to a vehicle, such as a truck, which is measured based on outputs of a plurality of load measurement sensors provided on the vehicle. The present invention relates to a vehicle loading state display device for displaying a loading state on a display unit.

2. Description of the Related Art Conventionally, in a large vehicle such as a truck, the load weight of the vehicle is measured based on the output of a weight measuring sensor such as a strain gauge sensor arranged near each wheel of the vehicle. In calculating the inclination of the vehicle, in order to correct the change in the output of each sensing element due to the inclination of the vehicle and measure the accuracy of the calculated loading weight, the vehicle inclination indicating the degree of inclination of the vehicle, and the inclination of each sensing element A loading state display device for a vehicle that calculates the loaded weight with the output corrected and displays the result is mounted.

In this vehicle loading state display device, when calculating the loading weight of a vehicle from the output of the sensing element of each wheel, the lateral direction of each axle is calculated based on the output of the sensing elements corresponding to the wheels at both ends of each vehicle. (The width direction of the vehicle) is calculated, and the left and right deviation values of each axle are weighted by counting according to the distribution of the respective dispersed loads according to the front, middle, and rear positions of the axle. The left and right deviation values of each vehicle are summed up to calculate the left and right deviation values of the entire vehicle.

In this integrated weight calculating device, the ratio of the total output of all sensing elements to the difference between the total output of each sensing element in front of the vehicle and the total output of each sensing element behind the vehicle is determined. Is the deviation value in the front-rear direction of the vehicle. Based on the left-right deviation value and the front-rear deviation value, the display lamp indicates which direction the load is deviating in front, rear, left and right.

However, such an indication of the direction in which the load of the vehicle is deviated in the front, rear, left and right directions can be used as a guide for loading the luggage so that the collapse of the load does not occur. It is important to note that if the load on the vehicle is actually biased in any of the front, rear, left, and right directions, it is necessary to transfer the load in which direction and how to reload the load in order to correct and eliminate it. Unless it is known beforehand that the bias of the load is eliminated, for example, trial and error must be repeated until the above-mentioned display lamp is completely turned off, and there is a problem that the efficiency is extremely low.

Therefore, a loading state display device for a vehicle for solving this problem has been proposed by the present applicant (Japanese Patent Application No. 10-57137). FIG. 11 is a view for explaining a conventional vehicle loading state display device.

As shown in FIG. 11, in this vehicle loading state display device, the direction of the relative deviation from the schematic diagram (solid line) of the deviation display graphic displayed on the display unit together with the schematic diagram (dashed line) of the vehicle. Thereby, it is possible to visually recognize the direction of the deviation of the load of the vehicle, which is indicated by the deviation of the vehicle measured based on the outputs of the plurality of load measurement sensors, in which direction. At the same time, the degree of deviation of the load of the vehicle is recognized based on the magnitude of the deviation of the deviation display graphic from the schematic diagram.

For example, when the load of the vehicle is deviated rightward and forward, a schematic diagram of a solid line is displayed at a position shifted to the right front from the schematic diagram of the broken line (see FIG. 11A), and the load of the vehicle is reduced. Is shifted to the left from the schematic diagram of the broken line, a schematic diagram of the solid line is displayed at a position shifted to the left (see FIG. 11B). If the load of the vehicle is biased to the rear of the left, A schematic diagram of a solid line is displayed at a position shifted to the rear left from the schematic diagram of the broken line (see FIG. 11C).

For example, when the loading weight is 0t, FIG.
As shown in (a), the load weight display area 41a of the schematic display area 41 is not turned on, and the center of gravity position display area 41 is displayed.
b is lit in orange at the approximate center of the loaded weight display area 41a, and the alarm area 41c is not lit. Loading weight is 2
In the case of t or less, as shown in FIG. 8 (b), the area up to the one-step portion of the loaded weight display area 41a is lit in green, and otherwise the same as FIG. 8 (a). When the load weight is 4t or less, as shown in FIG. 8C, the area up to the two-stage portion of the load weight display area 41a is lit in green, and the other areas are the same as in FIG. 8A.

The following description of FIGS. 9 (c) to 9 (i) also assumes that the loaded weight is 14t. Before the vehicle travels (N in step S2), no overloading has occurred (N in step S3), and the center of gravity position is deviated but is not a dangerously deviated load (step S6).
N), display pattern information corresponding to the load weight, the position of the center of gravity, and the like is generated in the RAM 33, and a display corresponding to the display pattern information is performed on the display unit 40 (step S9).
To S12).

For example, when the loading state is slightly deviated to the front, as shown in FIG. 9C, the center of gravity display area 41b moves one frame forward from the center of the loading weight display area 41a to the front of the loading platform of the vehicle. It is lit in orange with a slight shift, and all other areas of the seven stages of the loaded weight display area 41a are lit in green.

Similarly, when the loading state is largely deviated to the front, as shown in FIG. 9D, the center of gravity position display area 41b is moved from the center of the loading weight display area 41a to the front of the loading platform of the vehicle. Frame (loading weight display area 41a
Off to the front edge of the car carrier).

If the loading state is largely deviated to the front left side, as shown in FIG.
1b is displaced from the center of the load weight display area 41a to the left front of the vehicle bed (to the left front edge of the vehicle load bed in the load weight display area 41a) and is lit in orange.

If a dangerous uneven load has occurred (Y in step S6), the dangerous uneven load display information is stored in the RAM3.
3 (step S8), and display pattern information is generated based on the dangerous eccentric load display information (step S11). Then, as shown in FIG. 9 (i), according to the display pattern information, the center of gravity position display area 41b
Is shifted from the center of the loading weight display area 41a to the right rear of the vehicle loading platform (to the right rear edge of the loading platform of the vehicle in the loading weight display area 41a), and is lit in orange, for seven stages of the loading weight display area 41a. All areas are lit green,

The schematic display area 41 before traveling and the center-of-gravity position display area 41b are two frames forward from the center of the load weight display area 41a to the front of the vehicle bed (the front edge of the vehicle load bed in the load weight display area 41a). Until then, the display area 40 is alternately displayed with the schematic display area 41 after traveling, which is lit in orange with a shift.
