[0030] Vehicle overloading will directly affect the braking distance of the vehicle, reduce the braking performance of the vehicle, increase the danger of driving, and easily cause traffic accidents. Measure the vehicle load to prevent vehicle overloading.
[0031] At present, fixed vehicle load measurement systems are generally fixed in fixed places and fixed equipment, and the vehicle drives to a designated location to measure the vehicle load. However, fixed vehicle load measurement systems cannot monitor the vehicle load in real time, and there is a problem of poor timeliness.
[0032] In view of this, the utility model proposes a vehicle load measuring device.
[0033] Please refer to Figures 1 to 3 In the embodiment of the utility model, the vehicle load measurement device 10 includes a plurality of height sensors 100, the height sensors 100 include a circuit board 110, and a sensor body 120 disposed on the circuit board 110, and at least one height sensor 100 also includes an ECU unit 130 disposed on the circuit board 110; wherein the sensor body 120 is used to measure the vehicle height change value before and after the vehicle is loaded, the ECU unit 130 is used to receive the vehicle height change value and calculate the vehicle load value, and the ECU unit 130 is used to communicate with the vehicle display device 21 (please refer to Figure 4 ) communication connection to send the vehicle load value to the display device 21 for display.
[0034] Specifically, the vehicle load measurement device 10 includes a plurality of height sensors 100, which are installed between the suspension and the vehicle body beside the wheel. The height sensor 100 includes a circuit board 110 and a sensor body 120, wherein the sensor body 120 is arranged on the circuit board 110, and an ECU unit 130 is arranged on the circuit board 110 of at least one height sensor 100.
[0035] When the vehicle is loaded, the height of the vehicle changes, and the height sensor 100 can measure the change in the height value of the vehicle, that is, the sensor body 120 can measure the height change value of the vehicle before and after the vehicle is loaded. The height value of the vehicle refers to the height distance between the bottom plate of the vehicle body and the ground. Generally, the vehicle body will sink after the vehicle is loaded, that is, the distance between the bottom plate of the vehicle body and the ground will become smaller. In one embodiment, the vehicle is a van, and the height value of the vehicle body refers to the height distance between the bottom plate of the cargo compartment and the ground. The ECU unit 130 is connected to the sensor body 120 in communication to receive the height change value of the vehicle body measured by the sensor body 120. After receiving the signal of the height change value of the vehicle body, the ECU unit 130 calculates the load value of the vehicle through the algorithm strategy and control logic, and transmits the load value of the vehicle to the display device 21 of the vehicle. Generally, the display device 21 is a display instrument panel of the vehicle, so that it is convenient for the operator to intuitively observe the load information of the vehicle from the display instrument panel. In one embodiment, the ECU unit 130 transmits the vehicle load information to the instrument panel via the CAN line through the vehicle communication protocol, and displays the load information on the instrument panel. It is worth noting that the algorithm strategy and control logic of the ECU unit 130 for converting the vehicle height change value into the vehicle load value are prior art and will not be described in detail here.
[0036] In this way, the vehicle load measurement device 10 is installed on the vehicle body, so that the vehicle load measurement device 10 can move with the vehicle, which is convenient for real-time detection of the vehicle load condition, thereby improving the timeliness of the vehicle load measurement. Compared with the separately arranged ECU unit 130, the utility model integrates the ECU unit 130 in the height sensor 100, so that the integrated height sensor 100 can directly measure the vehicle body height change value and calculate the vehicle load value to directly output the vehicle load value. In this way, the volume of the vehicle load measurement device 10 is reduced, which is conducive to the installation of the vehicle load measurement device 10.
[0037] The number of height sensors 100 can be consistent with the number of wheels, that is, a height sensor 100 is installed between the suspension and the vehicle body next to each wheel. The height sensor 100 can measure the change value of the vehicle height at the wheel. Compared with the technical solution of only setting one height sensor 100 in the vehicle load measurement system 20, the technical solution of the utility model makes the measurement result more accurate. In one embodiment, the vehicle has four wheels, namely, the front right wheel, the front left wheel, the rear right wheel, and the rear left wheel. Accordingly, four height sensors 100 are also provided, thereby improving the measurement accuracy of the vehicle load information.
[0038] A technical solution of the utility model is to set a plurality of height sensors 100 in the vehicle load measurement device 10, and the plurality of height sensors 100 are respectively installed between the suspension and the vehicle body beside the wheel to measure the vehicle body height value before and after the vehicle load at the wheel, so as to obtain the vehicle body height change value after the vehicle load. At the same time, an ECU unit 130 is integrated in at least one height sensor 100, and the ECU unit 130 is used to receive the vehicle height change value and calculate the vehicle load value, and the ECU unit 130 is used to communicate with the display device 21 of the vehicle to send the vehicle load value to the display device 21 for display. In this way, on the one hand, compared with the solution in the prior art that the vehicle needs to go to a fixed place for load measurement, the utility model installs the vehicle load measurement device 10 on the vehicle body, so as to facilitate the real-time measurement of the vehicle load, thereby improving the timeliness of the vehicle load measurement. On the other hand, compared with the prior art that only one sensor is set, the utility model is provided with multiple sensors, thereby improving the accuracy and precision of the measurement results of the vehicle load information. On the other hand, compared with a separately arranged ECU unit 130, the utility model integrates the ECU unit 130 in the height sensor 100, so that the integrated height sensor 100 can directly measure the vehicle body height change value and calculate the vehicle load value to directly output the vehicle load value. In this way, the volume of the vehicle load measuring device 10 is reduced, which is beneficial to the installation of the vehicle load measuring device 10.
[0039] Furthermore, an ECU unit 130 is provided on the circuit board 110 of a height sensor 100, and multiple height sensors 100 are respectively communicated with the ECU unit 130. The ECU unit 130 receives multiple vehicle height change values measured by the multiple height sensors 100 and calculates a vehicle load value.
[0040] Please refer to Figure 5 Specifically, in one embodiment, the vehicle load measurement device 10 includes a plurality of height sensors 100, and only one of the height sensors 100 is integrated with an ECU unit 130. That is, only one of the height sensors 100 is provided with an ECU unit 130 on its circuit board 110. The other height sensors 100 are respectively connected to the ECU unit 130 of the height sensor 100 in communication. In one embodiment, the other height sensors 100 are respectively connected to the ECU unit 130 in communication through a signal line, so that the vehicle height change values measured by the other height sensors 100 are respectively transmitted to the ECU unit 130. The ECU unit 130 receives the vehicle height change value transmitted by its own height sensor 100, and also receives the vehicle height change values transmitted by other height sensors 100, and obtains a vehicle load value through an algorithm strategy and control logic, that is, obtains the vehicle load value. At the same time, the ECU unit 130 is also connected to the display instrument panel through the CAN line through the vehicle communication protocol, so that the load information is displayed on the display instrument panel. In this way, the operator can observe the vehicle load value from the display device 21. In this way, the ECU unit 130 is integrated into the height sensor 100, so that the integrated height sensor 100 can directly measure the change in vehicle height and calculate the vehicle load value to directly output the vehicle load value. In this way, the volume of the vehicle load measuring device 10 is reduced, which is beneficial to the installation of the vehicle load measuring device 10.
[0041] It is worth noting that the communication connection between the ECU unit 130 and other height sensors 100 belongs to the existing technology. The algorithm strategy and control logic of the ECU unit 130 receiving multiple vehicle height change values and converting the multiple vehicle height change values into a vehicle load value are existing technology and will not be repeated here.
[0042] Furthermore, an ECU unit 130 is provided on the circuit board 110 of the multi-height sensor 100, and the multiple ECU units 130 respectively receive the vehicle height change values measured by the corresponding sensor body 120, and respectively calculate multiple vehicle load values, and the multiple ECU units 130 are respectively used to communicate with the vehicle's display device 21 to send the multiple vehicle load values to the display device 21 for display.
[0043] Please refer to Figure 4Specifically, in one embodiment, the vehicle load measurement device 10 includes a plurality of height sensors 100, and the plurality of height sensors 100 are integrated with an ECU unit 130. That is, an ECU unit 130 is provided on the circuit board 110 of each height sensor 100. The plurality of ECU units 130 are respectively connected to the display instrument panel via the CAN line through the vehicle communication protocol. In this way, the sensor body 120 of each height sensor 100 can measure the vehicle height change value at the installation location, and transmit the vehicle height change value to the ECU unit 130 of the height sensor 100, and the ECU unit 130 receives the vehicle height change value and calculates the vehicle load value at the location through the algorithm strategy and control logic. Each ECU unit 130 transmits the vehicle load value measured at the location to the instrument panel, and the instrument panel will display a plurality of vehicle load values. The operator adds up the plurality of vehicle load values to obtain the overall load value of the vehicle. In this way, the ECU unit 130 is integrated into the height sensor 100, so that the integrated height sensor 100 can directly measure the vehicle body height value and calculate the vehicle load value to directly output the vehicle load value. In this way, the volume of the vehicle load measuring device 10 is reduced, which is beneficial to the installation of the vehicle load measuring device 10.
[0044] It is worth noting that the algorithm strategy and control logic for an ECU unit 130 to receive the vehicle height change value at that location and calculate the vehicle load value at that location belong to the prior art and will not be elaborated here.
[0045] Furthermore, the ECU unit 130 includes a single chip microcomputer 131, and the single chip microcomputer 131 is in communication connection with the sensor body 120. Figure 3 Specifically, the single-chip microcomputer 131 is an integrated circuit chip, which is a small and complete microcomputer system that integrates a central processing unit CPU with data processing capability, a random access memory RAM, a read-only memory ROM, a variety of I / O ports and interrupt systems, timers / counters and other functions on a silicon chip using ultra-large-scale integrated circuit technology. In the height sensor 100, the single-chip microcomputer 131 is responsible for algorithm strategy and logic control. The height sensor 100 integrated with the ECU unit 130, the single-chip microcomputer 131 and the sensor body 120 of the height sensor 100 are both arranged on the same circuit board 110, and the single-chip microcomputer 131 and the sensor body 120 are connected to each other through a circuit. The sensor body 120 of the height sensor 100 without the ECU unit 130 can be connected to the single-chip microcomputer 131 through a signal line. It is worth noting that the connection method between the single-chip microcomputer 131 and the sensor body 120 is a prior art and will not be repeated here.
[0046] More specifically, in one embodiment, the sensor body 120 uses a signal chip. When the vehicle is loaded, the height of the vehicle body changes, which will drive the installation angle of the height sensor 100 installed on the vehicle body to change. The change in the angle of the height sensor 100 will drive the magnetic field of the height sensor 100 to change. The signal chip receives the signal from the change in the magnetic field, and the signal is transmitted to the single-chip microcomputer 131. The single-chip microcomputer 131 processes the signal through internal algorithm strategy and logic control, outputs the calculation result to the CAN bus, and the CAN transmits and displays the load information on the instrument.
[0047] Furthermore, the ECU unit 130 further includes a cache chip 132, and the cache chip 132 is in communication with the single-chip computer 131. Figure 3 The cache chip 132 can improve the computing power of the single-chip microcomputer 131, improve the processing speed of the single-chip microcomputer 131, and make the measurement of the vehicle load information more timely.
[0048] The utility model also proposes a vehicle load measurement system 20, which includes a vehicle load measurement device 10 and a mounting assembly.
