Description

Vehicle ADB system testing method

Technical Field

The invention relates to the technical field of vehicle testing, in particular to a vehicle ADB system testing method.

Background

With the rapid development of the domestic lamp industry and the improvement of the requirements of people on driving safety and driving comfort, the traditional headlamp only comprising two illumination modes of near light and far light cannot completely meet the requirements of people. An Adaptive high Beam (ADB) lighting system is developed, which can adjust the distribution of high Beam to form a shadow area around the front vehicle and the oncoming vehicle, thus ensuring the sight distance of the driver and avoiding glare for other road users.

In the standard system of lamps and lanterns and lights of motor vehicles at present, only GB 4785-2019' installation regulations of external lighting and light signal devices of automobiles and trailers and the currently established integration standard of front lighting systems are relevant standards of an adaptive high beam system (ADB); the current effective adaptive front lighting system does not contain the content of the adaptive high beam. GB4785-2019 has the requirement of a self-adaptive high beam path test, but the requirement is simpler, only whether the self-adaptive high beam can be automatically turned on and off and cause glare is checked, and a test scheme required by the path test is not mentioned; the integration standard of a front lighting system in the manufacturing belongs to the light distribution requirement of a lamp part level, and does not have the road test requirement of a whole vehicle level. However, the ADB system is a finished automobile level system consisting of four parts, namely a sensor, a transmission channel, an ECU (electronic control unit) and an actuating mechanism, and the current standard assessment items only aim at single-product lamps and are fixed working conditions, so that the problem of missing finished automobile level test standards exists. Therefore, a set of test methods for the ADB system is needed to examine the actual working capability thereof.

Currently, there are two main approaches to testing ADB systems. The first method is to carry out light distribution test in a laboratory to evaluate the requirement of the ADB system on the luminous intensity under different modes; the second is a road test performed on a real vehicle to check whether the ADB system can be automatically turned on or off. However, both methods cannot perform quantitative test on the performance of the ADB system of the whole vehicle level.

FIG. 1 illustrates a block flow diagram of a vehicle ADB system testing method in accordance with one embodiment of the present invention. As shown in the figure, the invention provides a vehicle ADB system testing method, which comprises the following steps:

s1, selecting a test vehicle and a target vehicle, configuring an ADB system to be tested on the test vehicle, and respectively setting a VBOX in the test vehicle and the target vehicle. VBOX is an intelligent testing instrument with a high-performance microcomputer as a core, and obtains running parameters of a test vehicle, such as vehicle speed, braking, coasting and the like, through other testing equipment. The VBOX can display the test data and generate a curve in real time, is clear and visual, automatically stores the test parameters and results, and is not lost when power is down; meanwhile, a standard RS232 interface is arranged, a test result can be sent out, and a user can conveniently perform secondary analysis processing or storage on the data acquired by the VBOX by using a system machine or a notebook computer.

And S2, setting an illuminometer on the target vehicle based on the test scheme, and connecting the illuminometer to the VBOX of the target vehicle. An illuminometer is a scientific instrument specially used for measuring the illuminance, and is used for measuring the degree of illumination of the surface of an object. A typical illuminometer is used to measure visible light illumination in the wavelength range 380 to 780 nm. An illuminometer is provided on the target vehicle for obtaining an illuminance value of the test vehicle headlamp for characterizing glare caused by the test vehicle. The glare is a psychological parameter for measuring the subjective reaction of discomfort caused by outdoor stadiums and other outdoor field lighting devices to human eyes, and the value of the psychological parameter can be calculated according to a CIE glare value formula.

And S3, each test scheme can contain one or more test scenes. Implementing each test scenario in the test scenario, including:

and S31, zeroing the illuminometer and activating the ADB system. Specifically, the illuminometer is zeroed before each test is started. For a bend test conducted in an environment with ambient light, such as moonlight or other infrastructure lighting, the illuminometer should be zeroed in the direction of maximum ambient light. The target vehicle light should remain unchanged during the test.

And S32, testing is carried out based on the test scene, at each moment of the test time period, the VBOX arranged on the target vehicle obtains the glare value of each illuminometer, and the two VBOX synchronously obtain the position information of the corresponding vehicles.

Preferably, in step S1 or S2, a GPS device is provided on each of the test vehicle and the target vehicle. Each GPS device is accessed into VBOX of each corresponding vehicle, and the VBOX obtains position information of the corresponding vehicle through the GPS device. As is readily understood, at the same time, the VBOX on the test vehicle acquires the position information of the test vehicle, and the VBOX of the target vehicle acquires the position information of the target vehicle and the glare value of the illuminometer.

Preferably, the GPS device is a GPS range finder or a GPS antenna. The GPS range finder is used for acquiring the moving distance of the corresponding vehicle. The GPS antenna is used for acquiring the position coordinates of the corresponding vehicle. Conventionally, a GPS range finder is preferably used, which is also capable of acquiring the position coordinates of the vehicle and calculating the distance between the starting point and the time at different times.

in the third scheme, the test vehicle 201 and the target vehicle 202 are positioned on adjacent straight lanes and run in the same direction;

according to the fourth scheme, the test vehicle 201 and the target vehicle 202 are located in adjacent curved lanes and run in the same direction;

the speed of the test vehicle 201 is greater than or equal to that of the target vehicle 202, and the test vehicle 201 is located in the left lane when the vehicle runs in the same direction and is located in the adjacent lane;

Preferably, in step S32, the vehicle speed of the target vehicle 202, the vehicle speed of the test vehicle 201, and the test distance are set according to the test scenario;

if the fourth aspect is selected in step S2, the curve radius of the set curved lane is increased in step S32. Wherein the test distance is used to characterize the distance of the intersection of a horizontal plane through the headlight light source of test vehicle 201, a vertical plane through the headlight light source of test vehicle 201, and a vertical plane through the longitudinal centerline of test vehicle 201 to the forwardmost end of the illuminometer on target vehicle 202.

It should be noted that for each test scenario, the target vehicle 202 and the test vehicle 201 meet the speed requirements of table 2. Before the test formally starts, the speeds of the target vehicle 202 and the test vehicle 201 need to reach ± 0.45m/s of the vehicle speed specified in table 2, and the vehicles are kept within the specified range throughout the test distance. At each test section, once the test speed is reached, it must be maintained all the time, and it should not suddenly accelerate or brake.

Since the target vehicle 202 and the test vehicle 201 in the second to fourth schemes are traveling in the same direction, attention is paid to the feeling of the driver of the target vehicle 202 from the rear view mirror to the high beam, and the arrangement position of the illuminance meter 203 is different from that in the first scheme. Referring to fig. 7a and 7c, two of the three illuminometers 203 are provided on the driver-side and passenger-side rearview mirrors 207, respectively, and the other illuminometer 203 is provided to the interior rearview mirror 207 of the target vehicle 202.

Meanwhile, the capacity of the vehicle battery is in a full state, so that the voltage in the headlamp testing process is basically kept stable and is not influenced.
