Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
In order to realize vehicle testing, at least one vehicle to be tested needs to be prepared, a testing environment needs to be established, then a vehicle testing device issues testing contents to the vehicle, and the safe driving performance of the vehicle is evaluated based on the testing performance of the vehicle. The vehicle to be tested, the test environment, the vehicle testing apparatus, and the test procedure are described below, respectively.
The vehicle to be tested is described below, which may be, for example, a service vehicle with a higher safety requirement or a passenger vehicle. The following embodiments will be described by taking a commercial vehicle as an example.
Firstly, a to-be-tested operation vehicle is prepared and is ensured to be in a normal working condition that the vehicle can be put into operation for use, such as sufficient electric quantity of a storage battery and sufficient gasoline.
In order to evaluate the safe driving performance of a commercial vehicle, some sensor devices need to be installed on the vehicle. To determine which sensors to use, it is necessary to first determine an evaluation index of the safety performance. In the embodiment, the driving safety is measured from two situations of avoiding collision and rollover, for example, so that sensors such as an ultrasonic radar are selected to judge the collision condition, a pressure sensor is adopted to determine the pressure condition of a tire and a road surface, and embedded equipment is used for recording and analyzing signals obtained by the sensors.
And arranging a plurality of ultrasonic radars on the surface of the vehicle body, and calibrating the ultrasonic radars. According to the test requirement, the distribution of the ultrasonic radar can cover the vehicle body, so that any obstacle in a certain early warning range around the vehicle body can be effectively monitored finally, and the distribution of the ultrasonic radar can cover the front end of the vehicle or the part of the measuring end.
Pressure sensors are disposed on respective tires of a vehicle. The critical condition that the vehicle rolls over is that the pressure of at least one wheel and the ground tends to be 0, so the roll-over condition can be monitored by using the pressure sensor.
And (3) collecting and analyzing induction signals detected by the pressure sensor and the ultrasonic radar sensor according to a time sequence by using vehicle-mounted embedded equipment. Through analysis, once the operating vehicle is found to be too close to a surrounding obstacle (smaller than a preset distance, early warning collision) or a certain tire pressure signal tends to 0 (smaller than a preset pressure, early warning rollover), the potential safety hazard of the vehicle is judged to be about to occur, a vehicle braking system is immediately controlled to stop the vehicle in an emergency, and a safety evaluation failure result is reported according to a current test project. There are many test items, and the test result of the current test item needs to be reported in real time. The test result of the current test item is transmitted to the vehicle testing device at the environment end through the wireless device, and receives a next test instruction transmitted by the vehicle testing device, and the format of the test instruction can be voice guidance (suitable for the piloted vehicle) or a digital signal format instruction with a specific format (suitable for the pilotless vehicle).
An exemplary test environment is described below. Obviously, the test method of the present disclosure is not limited to such a test scenario, and other test environments may also be applicable to the test method of the present disclosure.
In order to fully test the running conditions of a commercial vehicle under various working conditions, several types of test environment elements are prepared, and a specific test environment can be formed by randomly combining the test environment elements so as to evaluate the safety performance of the vehicle in the test environment.
The categories of the environment elements of the present embodiment include: the coefficient of road friction (further including the road material and the degree of road dryness), the degree of road inclination, and the degree of lane curvature.
And aiming at the road surface friction coefficient, various road surface conditions are selected to simulate the road surface friction coefficient possibly occurring in actual operation. The selected pavement materials include, for example, the following 6 types: asphalt, fine sand, masonry, wood, plastic and concrete, and under the premise of selecting each material, two options of wetting the pavement or keeping the pavement dry are further selected, so that 12 pavement friction coefficient conditions can be constructed as candidate factors of the pavement condition. The material and amount of the road surface are only used as an example and not as a limitation, and other materials and amounts of the road surface can be selected according to the test requirements.
For the class of the inclination degree of the road surface, the road surfaces with two inclination degrees are arranged: one is a horizontal road surface, i.e. not containing any inclination; the other is to incline a certain angle along the direction orthogonal to the extending direction of the road, and the angle value can be determined by referring to the limit angle in the industry standard or the national standard in the road paving field and combining the actual requirement of the user. For example, if the operating vehicle to be tested can run safely on such a slope, a steeper slope than this does not appear in reality, so that the driving safety of the vehicle is ensured.
According to the lane bending degree type, a plurality of concentric annular regions are arranged, two adjacent concentric annular regions are connected through a straight lane, each concentric annular region comprises a plurality of concentric annular lanes with different curvatures, and at least one of the road surface material and the inclination degree of the different concentric annular lanes is different. Assuming that the minimum turning radius of the vehicle itself is R, the curvature radius of the circular lane may be set to 5 values of + ∞, 2R, 1.5R, R, and 0.9R, respectively. Obviously, the smaller the curvature radius of the lane is, the larger the road curvature degree is, and the rollover probability of the commercial vehicle is correspondingly increased. In the lane environment of 0.9R, when the commercial vehicle cannot drive through the excessively curved road at one time without reversing, a scene is added, and whether the dangerous behavior that the vehicle can abandon the one-time driving through the curved road at one time after judgment can be evaluated. A lane with a radius of curvature of + ∞isequivalent to a straight lane.
In summary, based on road surface conditions of 6 materials, 2 grades and 5 curvatures, the independent elements are combined to form a road scene of 6 × 2 × 5 ═ 60. And by matching with Boolean type operation variables of whether water is sprayed or not, 120 road scenes can be obtained. During specific implementation, the operation vehicle can carry out driving test in 60 dry road scenes, then sprinkle water on the dry road, and then continue driving test in 60 wet road scenes, so that the test of the whole 120 scenes can be carried out.
FIG. 1 shows a schematic diagram of the concentric annular zone test environment set-up of the present disclosure. As shown in fig. 1, the first concentric annular region is an asphalt horizontal pavement 11, the second concentric annular region is an asphalt inclined pavement 12, and the third concentric annular region is a fine sand horizontal pavement 13, each concentric annular region including a plurality of concentric annular lanes having different curvatures, such as lanes 111, 112, 121, 122, 131, 132, the outer lanes 111, 121, 131 having smaller curvatures than the inner lanes 112, 122, 132. The vehicle can run in different annular lanes corresponding to different curvature radiuses, then runs from the concentric annular area to the entrances of the straight lanes 14 and 15, and can migrate to the next concentric annular area through the straight lanes connected between different concentric circles to complete the test of other scenes. The construction mode of the test environment can improve the land use efficiency, so that the vehicle can finish the test of various lane environments one by one in a seamless connection and in a one-step manner.
In addition, static obstacles can be arranged in the scene, and vehicles to be tested need to avoid the static obstacles. The static obstacle may be, for example, a guardrail or curb, etc., and may be disposed at the edge of the roadway.
In addition, in the test scene, a road end device can be further arranged, and the road end device is used for transferring information between the vehicle and the vehicle test device. For example, the vehicle testing apparatus issues a test task to the road-end device, where the test task may include a plurality of test items, and in order to reduce the pressure stored in the vehicle-end system, the road-end device issues the test items to the vehicles one by one, the vehicles complete one test item, and the road-end device then sends the next test item to the vehicles. Because the road-end equipment is close to the vehicle, the delay problem of information receiving and sending can be ignored. In addition, the information such as the single test result reported to the vehicle testing device by the vehicle can also be uploaded through the road end equipment. If no road end equipment exists, the vehicle and the vehicle testing device can communicate in a wireless mode; if the road end equipment exists, a wired communication mode with a higher transmission speed can be deployed between the road end equipment and the vehicle testing device, and a wireless communication mode is still deployed between the road end equipment and the vehicle.
The following describes a vehicle testing apparatus.
The vehicle testing device is a central processing system of the whole test, has corresponding software and hardware settings, and has the main function of receiving the test result of each current test item of the tested operating vehicle in real time and dynamically adjusting the test item list of the subsequent test according to the test result.
In a vehicle testing apparatus, an initial list of test items is maintained, wherein the order of the test items is determined based on the natural driving order of the vehicle in a test environment. When the vehicle actually drives into the test site and starts to finish the test items in the list one by one, the test items in the list can be dynamically adjusted along with the failure result of the tested items.
FIG. 2 is a schematic flow chart diagram of some embodiments of a vehicle testing method of the present disclosure. The method may be performed by a vehicle testing device.
As shown in fig. 2, the vehicle testing method of the embodiment includes:
in step 21, a test task is sent to the vehicle to be tested according to the test item list, so that the vehicle completes each test item in turn in the test environment according to the sequence of the test items in the list.
Wherein, the testing task can be all of the testing item list or the item needing testing firstly.
In step 22, the test result of the current test item fed back by the vehicle is obtained in real time during the test process. If the test result of the current test item is failed, executing step 23; if the test result of the current test item is successful, step 24 is performed.
As described above, if the sensing information of the ultrasonic radar equidistant sensor mounted on the surface of the vehicle body of the vehicle indicates that the distance between the obstacle and the vehicle is less than the preset distance, or if the sensing information of the pressure sensor mounted on the tire of the vehicle indicates that the tire pressure is less than the preset pressure, the vehicle determines that the test result of the current test item is failed, and reports the result to the vehicle testing device. If the test result is successful, reporting to the vehicle testing device.
At step 23, untested items having a greater difficulty factor than the current test item are deleted from the list of test items. Step 24 is then performed.
At step 24, the tested items are deleted from the list of test items.
In step 25, a test task is sent to the vehicle according to the updated list of test items, so that the vehicle completes each untested item in the test environment in sequence according to the sequence of the test items in the updated list.
Wherein, the test task can be all of the updated test item list or the item needing test firstly.
It should be noted that, the step 24 of deleting the tested item from the test item list is an optional step, and if the step 24 is not executed, the vehicle records the tested item by itself. In this case, as shown in fig. 3, the vehicle test method (which may be executed by the vehicle test apparatus) of the embodiment includes:
in step 31, a test task is sent to the vehicle to be tested according to the test item list, so that the vehicle completes each test item in turn in the test environment according to the sequence of the test items in the list.
Wherein the test task may be the entirety of the list of test items.
In step 32, the test result of the current test item fed back by the vehicle is obtained in real time in the test process. If the test result of the current test item is failed, executing step 33; if the test result of the current test item is successful, no processing is performed, that is, the test item list is not updated, so that the vehicle still completes each untested item in the test environment in sequence according to the sequence of the test items in the initial test item list.
At step 33, untested items having a greater difficulty factor than the current test item are deleted from the list of test items.
In step 34, a test task is sent to the vehicle according to the updated list of test items, so that the vehicle sequentially completes each untested item in the test environment according to the tested items recorded by the vehicle per se and the sequence of the test items in the updated list.
Wherein the test task may be the entirety of the updated list of test items.
In the embodiment corresponding to fig. 2 and fig. 3, in the testing process, the testing result of the current testing item fed back by the vehicle is obtained in real time, if the current testing item fails to be tested, the untested item with the difficulty coefficient greater than that of the current testing item is deleted from the initial testing item list, and then the testing of each of the remaining untested items is continuously completed according to the updated list, so that the testing efficiency can be improved, and the testing resources can be saved. In addition, compared with the embodiment corresponding to fig. 2, since the test item list does not need to be updated and issued when a single test item succeeds, communication resources can be saved, and the real-time performance of the test can be improved.
Further, the method of determining "untested item having a greater difficulty factor than the current test item" referred to in the above-mentioned steps 23 and 33 includes: and in each test environment element of the untested item, if at least one test environment element has a difficulty coefficient larger than that of the same test environment element of the current test item and the other test environment elements have the same difficulty coefficient as that of the same test environment element of the current test item, judging that the untested item has a difficulty coefficient larger than that of the current test item.
For example, if all the test items are 120, if the current test item is that the vehicle tests on a dry, horizontal and non-inclined asphalt pavement with a curvature radius of 2R, if rollover warning occurs in the test process, the vehicle reports that the current test item fails in the test, the test is interrupted, and the test item list is adjusted, at this time, the number of future test items is not 119 any more, but is further reduced. Since the vehicle cannot safely run through the dry asphalt ring-shaped lane with no inclination in the horizontal direction and the curvature radius of 2R, the more severe test items such as the dry asphalt ring-shaped lane with no inclination in the horizontal direction and the curvature radius of 1.5R or 0.9R do not need to be tested continuously, because the vehicle cannot safely run on a more curved road surface under the same conditions without rollover, the three test items are removed from the items to be tested, the updated item which needs to be tested firstly can be issued to the vehicle end, and the vehicle to be tested runs directly to the next item which is really worthy of testing. If the tested vehicle is an unmanned vehicle, the tested vehicle can directly run to the next test item based on the position of the test item, or run to the next test item based on the remote control of the test device, or other feasible modes are all suitable for the invention.
The method comprises the steps that a vehicle to be tested receives a test task sent by a vehicle test device (or the vehicle test device forwards through road-end equipment), a single test item is executed according to the priority sequence appointed by the test task, the vehicle is driven to a test place of the test item to start testing, in the test process, a vehicle-mounted embedded device continuously collects and analyzes induction signals of a pressure sensor, a distance sensor and the like, once the induction signal of the distance sensor of the vehicle shows that the distance between the vehicle and an obstacle is smaller than a preset distance, collision is early warned, or the induction signal of the pressure sensor shows that a tire is smaller than a preset pressure, rollover is early warned, at the moment, the potential safety hazard of the vehicle is judged to be generated, a vehicle is immediately controlled to be emergently stopped, and meanwhile, the result of failure of safety test of the current test item is reported, and waits for the vehicle testing device to issue the adjusted testing task (see the description of the foregoing embodiment for the adjustment strategy). And once the vehicle receives the adjusted test task, continuously executing the rest single test items according to the priority order appointed by the adjusted test task, and driving to the test site of the test item to continuously test until the test is finished.
