As shown in fig. 1, the front collision warning test apparatus may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may include a Display screen (Display), and the optional user interface 1003 may further include a standard wired interface and a wireless interface, and the wired interface for the user interface 1003 may be a USB interface in the present invention. The network interface 1004 may optionally include a standard wired interface, a WIreless interface (e.g., a WIreless-FIdelity (WI-FI) interface). The Memory 1005 may be a Random Access Memory (RAM) or a Non-volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a definition of a test device for front impact warning, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, a memory 1005, identified as one type of computer storage medium, may include an operating system, a network communication module, a user interface module, and a pre-crash warning test program.
In the testing device for early warning of a front collision shown in fig. 1, the network interface 1004 is mainly used for connecting to a background server and performing data communication with the background server; the user interface 1003 is mainly used for connecting user equipment; the test equipment for the front collision warning calls a test program for the front collision warning stored in the memory 1005 through the processor 1001, and executes the test method for the front collision warning provided by the embodiment of the invention.
Based on the hardware structure, the embodiment of the test method for the front collision early warning is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the front collision early warning testing method of the present invention, and provides the first embodiment of the front collision early warning testing method of the present invention.
In a first embodiment, the method for testing the front collision warning includes the following steps:
step S10: and confirming the basic functions of the test vehicle with the pre-collision early warning system to obtain basic function confirmation results.
It should be understood that the execution subject of the present embodiment is a control device of the front collision warning test. The control device may be a remote connected device such as a separate computer or server, or may be a control device installed in a vehicle such as a vehicle-mounted computer. The control equipment comprises an information acquisition module and an information processing module, wherein the information acquisition module is used for acquiring basic information of the test vehicle, and the information processing module is used for determining the current state of the test vehicle according to the acquired basic information and sending out a related instruction to test a front collision early warning system on the test vehicle.
It should be noted that the front collision warning system is a system for determining whether there is a collision risk between the test vehicle and the vehicle in front. The front collision early warning system can detect the front vehicle at any time through the radar system, judge the distance, the direction and the relative speed between the front vehicle and the vehicle, and warn a driver when potential collision danger exists. The front collision early warning system does not adopt any braking measures to avoid collision or control the vehicle, but can send out an alarm to prompt a driver to operate so as to avoid the test vehicle from sending collision with a target vehicle in front. The basic function refers to whether the vehicle can normally complete the related function of the front collision early warning test. For example, whether the vehicle can start or close the front collision early warning system, whether the front collision early warning system can be normally activated, whether the front collision system can normally give an alarm when determining that the collision risk exists, and the like. When any basic function cannot be started normally, the test vehicle cannot test the front collision early warning system. The basic function confirmation result is a result obtained after the basic function of the test vehicle is confirmed. The basic function confirmation result may be a confirmation result that the basic function is confirmed without error or a confirmation result that the basic function is confirmed with error.
In specific implementation, the control device may confirm the basic functions of the test vehicle on which the front collision warning system is mounted by testing each basic function in the front collision warning system in advance, so as to obtain a basic function confirmation result. For example, the control device may actively turn on or turn off the front collision early warning system to determine whether the front collision early warning system can normally receive an on or off instruction of the control device, and the control device may also determine the activation, alarm, and other modes of the front collision early warning system by this way; of course, the confirmation may be performed in other manners, and is not limited in particular.
Step S20: and when the basic function confirmation result is that the confirmation is correct, determining the current test working condition of the target vehicle positioned in front of the test vehicle.
It should be noted that the target vehicle is an auxiliary vehicle for testing a front collision warning system mounted on the test vehicle. The target vehicle needs to be located directly in front of the test vehicle. The current test condition refers to a current running state of the target vehicle. In an embodiment, the current test conditions include: the target vehicle static working condition, the target vehicle low-speed running working condition and the target vehicle deceleration working condition. The target vehicle low-speed running working condition refers to a working condition that the speed of the target vehicle is lower than that of the test vehicle; the target vehicle deceleration condition refers to a condition in which the speed of the target vehicle after deceleration is lower than the speed of the test vehicle. In the concrete test process, the vehicle to be tested is gradually close to the target vehicle in front, and under different working conditions, the speed of the target vehicle and the speed of the vehicle to be tested need to be limited, so that the meaningless test process is avoided.
In a specific implementation, the control apparatus may determine the current test condition of the target vehicle located ahead of the test vehicle by receiving the instruction when the basic function confirmation result confirms that there is no failure. For example, the control device may receive an instruction sent by a person to control a target vehicle operating condition, and determine a current test operating condition of the target vehicle based on the instruction. Of course, the control device may also set through a program when the target vehicle needs to be tested on the front collision warning system under any one of the above working conditions, and the control device determines the current testing working condition of the target vehicle according to the program.
Step S30: and determining a first running parameter of the target vehicle and a second running parameter of the test vehicle according to the current test working condition.
It should be noted that the first driving parameter refers to parameter information of the target vehicle driving under the current test condition; similarly, the second parameter information refers to the parameter information for testing the running of the vehicle under the current test working condition. The first parameter information may be parameter information such as speed information, acceleration information, and the like of the target vehicle. The second parameter information may be speed information, acceleration information, step length, etc. of the target vehicle. The first driving parameters of the target vehicle and the second driving parameters of the test vehicle under different working conditions need to be determined in advance before the front collision early warning system is tested. In this embodiment, the mapping table may be established, and certainly, the mapping table may also be established in other manners, which is not specifically limited herein.
In specific implementation, the control device may obtain the first driving parameter of the target vehicle and the second driving parameter of the test vehicle by searching a preset mapping table according to the current test condition. But may also be used in other ways, and is not limited in this respect.
Step S40: and controlling the target vehicle to run according to the first running parameter, controlling the test vehicle to run according to the second running parameter, and performing a front collision early warning test.
It should be noted that, in the present embodiment, the control device may control the target vehicle to travel according to the travel state of the first travel parameter by sending an instruction, and may also control the test vehicle to travel according to the form state of the second travel parameter. At the moment, the distance between the test vehicle and the target vehicle is gradually reduced along with the change of the test time, and when the distance between the test vehicle and the target vehicle is smaller than a certain value, whether a front collision early warning system on the target vehicle gives an alarm or not is determined, so that the front collision early warning test is completed.
In the embodiment, a method for testing front collision warning is provided, which obtains a basic function confirmation result by confirming a basic function of a test vehicle loaded with a front collision warning system; determining the current test working condition of a target vehicle positioned in front of the test vehicle when the basic function confirmation result is that the confirmation is correct; determining a first running parameter of a target vehicle and a second running parameter of a test vehicle according to the current test working condition; and controlling the target vehicle to run according to the first running parameter, controlling the test vehicle to run according to the second running parameter, and performing a front collision early warning test. In the embodiment, the basic function of the test vehicle is confirmed, and when the basic function is confirmed to be correct, the target vehicle is controlled to run by determining the first running parameter, and the test vehicle is controlled to run by the second running parameter and a front collision early warning test is carried out, so that the test of the driving assistance system technology of the front collision early warning system is completely realized.
Referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of the front collision warning testing method according to the present invention, and the second embodiment of the front collision warning testing method according to the present invention is proposed based on the first embodiment shown in fig. 2.
In the second embodiment, the step S10 includes:
step S11: and confirming the main switch function of the test vehicle of the pre-loading collision early warning system to obtain a main switch confirmation result.
It should be noted that the main switch function refers to a function of turning on or off the front collision warning system of the test vehicle according to an input command. When the main switch has a fault function, the control equipment cannot control the front collision early warning system to be turned on or turned off when receiving an input instruction. The main switch confirmation result means a result obtained after the main switch function is confirmed. The main switch confirmation result includes a main switch error-free confirmation result and a main switch error confirmation result.
In specific implementation, the control device may turn on or turn off the front collision early warning system according to the input instruction by receiving the input instruction, monitor whether the front collision early warning system is turned on or off correspondingly in real time, and obtain a main switch confirmation result according to the detected information. And the control equipment starts or closes the front collision early warning system according to a corresponding instruction, and outputs a confirmation result that the main switch is not wrong when the front collision early warning system is correspondingly changed, otherwise, outputs a confirmation result that the main switch is wrong.
Step S12: confirming the display function of the test vehicle to obtain a display function confirmation result, wherein the display function comprises the following steps: an activation function and an alarm trigger function.
The display function is a function for displaying the function related to turning on or off of the test vehicle. When the test vehicle starts or closes any function, the display module displays the changed state of the function, namely, the change of any function is intuitively reflected when the function is displayed. For example, when the vehicle is running, the turn signal of the vehicle is turned on, and after the turn signal is normally turned on, the currently turned on turn signal of the vehicle is displayed on the instrument panel. The activation function refers to a function of activating the front collision early warning system by the test vehicle. When the front collision early warning system is started, whether the front collision early warning system can normally determine that the collision risk exists between the test vehicle and the target vehicle is required, namely whether the front collision early warning system can be normally activated is required to be determined. The alarm triggering function is a function of triggering an alarm by the front collision early warning system when a collision risk exists between the test vehicle and the target vehicle.
In specific implementation, the control device can start the front collision early warning system under a certain condition, detect the display module of the test vehicle in real time, confirm that the display module of the test vehicle can normally display the started front collision early warning system, and record the display result of the display module as the confirmation result of the display function.
Step S13: and obtaining a basic function confirmation result according to the main switch confirmation result and the display function confirmation result.
It should be noted that the basic functions include a main switch function and a display function, the control device may integrate the main switch confirmation result and the display function confirmation result when the main switch function confirmation result and the display function confirmation result are obtained, and may obtain a basic function confirmation result without an error in the basic functions when both the main switch confirmation result and the display function confirmation result are correct, or obtain a basic function confirmation result with an error in the basic functions.
Wherein the step S11 includes:
step S111: and adjusting the gear of the test vehicle, and in the gear adjusting process, turning on and off a switch of the front collision early warning system according to the current gear state to obtain the display states of an instrument indicator light and an instrument interface.
When the main switch function is confirmed, the main switch function needs to be confirmed when the shift position of the test vehicle is in a different shift position. For example, when the vehicle gear is in the D gear, the reverse image system of the vehicle is not normally activated, and when the vehicle gear is in the R gear, the reverse image system of the vehicle is normally activated. In the gear adjustment process, the main switch function in the current gear state can be confirmed. The display state of the instrument indicator lamp and the instrument interface refers to the current display state of the instrument indicator lamp and the instrument interface when the main switch function of the test vehicle is confirmed.
In specific implementation, the control device may turn on and off the switch of the front collision early warning system according to the current gear state in the gear adjustment process, confirm the main switch function of the front collision early warning system in the current gear, and record whether the display states on the instrument indicator lamp and the instrument interface have the on or off state of the front collision early warning system.
Step S112: and confirming the function of the main switch according to the display states of the instrument indicating lamp and the instrument interface to obtain a main switch confirmation result.
It should be noted that the display states of the instrument indicator light and the instrument interface are the most direct indication of whether the main switch functions are normal or not. When the display states of the instrument indicating lamp and the instrument interface are determined, the function of the main switch can be confirmed according to the display states of the instrument indicating lamp and the instrument interface. In the specific implementation process, when the display states of the indicator light of the instrument and the instrument interface are consistent with the instruction of turning on or off the front collision early warning system, a confirmation result that the main switch is not wrong is output, and otherwise, a confirmation result that the main switch is wrong is output.
The step S12 includes:
step S121: and controlling the test vehicle to run at a first preset speed so as to confirm the activation function of the front collision early warning system and obtain an activation function confirmation result.
It should be noted that the first preset speed is a speed for confirming whether the activation function of the front collision warning system is normal. The activation function confirmation result refers to a result obtained after the activation function is confirmed. The activation confirmation result includes an activation confirmation result without an activation function error and an activation confirmation result with an activation function error.
In specific implementation, the control device may control the test vehicle to travel at a first preset speed on a road in which the test vehicle normally travels, determine whether a front collision warning system of the test vehicle enters an activated state, and obtain a determination result as an activation function confirmation result. For example, the vehicle runs in the center of a road, the speed of the vehicle is 30km/h, whether the front collision early warning system enters an activated state or not is judged, and test result records are recorded.
Step S122: and when the target vehicle is static, controlling the test vehicle to run in the same direction of the target vehicle at a second preset speed so as to confirm the alarm triggering function of the front collision early warning system and obtain an alarm triggering function confirmation result.
It should be noted that the second preset speed refers to a speed of the vehicle being tested when the alarm triggering function of the front collision early warning system is confirmed. When testing the alarm triggering function, the alarm condition needs to be satisfied. And under the condition of meeting the alarm condition, judging whether the alarm triggering function can be normally triggered to alarm. The alarm triggering function confirmation result is a result obtained after the alarm triggering function is confirmed. The alarm trigger function confirmation result comprises an alarm trigger function confirmation result with no alarm trigger function error and an alarm trigger function confirmation result with an alarm trigger function error.
In a specific implementation, the control device may control the test vehicle to run at a second preset speed on a road in which the test vehicle normally runs, determine whether a front collision early warning system of the test vehicle is normally alarming, obtain a determination result as an alarm triggering function confirmation result, for example, a gear of the test vehicle is engaged to a D gear, the target vehicle is stationary, the test vehicle runs in the same direction at a speed of 40km/h, when a distance between the test vehicle and the target vehicle is less than a certain value, determine whether to trigger an alarm, and record the result.
Step S123: and obtaining a display function confirmation result according to the activation function confirmation result and the alarm trigger function confirmation result.
It should be noted that the display function includes an activation function and an alarm trigger function. In the case where both the activation function confirmation result and the alarm trigger function confirmation result are obtained, the control device may sort the activation function confirmation result and the alarm trigger function confirmation result into one set, and use the sorted set as the display function confirmation result.
In the embodiment, a method for testing front collision warning is provided, which obtains a basic function confirmation result by confirming a basic function of a test vehicle loaded with a front collision warning system; determining the current test working condition of a target vehicle positioned in front of the test vehicle when the basic function confirmation result is that the confirmation is correct; determining a first running parameter of a target vehicle and a second running parameter of a test vehicle according to the current test working condition; and controlling the target vehicle to run according to the first running parameter, controlling the test vehicle to run according to the second running parameter, and performing a front collision early warning test. In the embodiment, by confirming each function in the basic functions of the test vehicle, when each function is confirmed to be correct, the target vehicle is controlled to run by determining the first running parameter, the test vehicle is controlled to run by the second running parameter, and the front collision early warning test is carried out, so that the test of the driving assistance system technology of the front collision early warning system is completely realized.
Referring to fig. 4, fig. 4 is a flowchart illustrating a third embodiment of a front collision warning testing method according to the present invention, and the third embodiment of the front collision warning testing method according to the present invention is proposed based on the first embodiment illustrated in fig. 2.
In the third embodiment, before the step S10, the method further includes:
step S101: after the test vehicle is started, adjusting the test speed of the test vehicle, and performing preheating braking on the test vehicle when the test speed reaches the target speed required by the brake system for preheating currently.
Note that the warm-up brake is a brake for warming up the brake system. The brake system of the test vehicle needs to be warmed up before the test vehicle starts the test. The test speed refers to the speed at which the test vehicle is performing the test. The target speed is a speed required when the brake system is braked. The corresponding brake preheating may be different in different scenes, and the corresponding target speeds are also different. Different target speeds may also be required during the preheating process in the same preheating scenario.
In specific implementation, after the test vehicle is started, the control device may adjust the test speed of the test vehicle by controlling the accelerator opening of the test vehicle, and when the test speed reaches the target speed currently required by the brake system, the test vehicle is braked until the test vehicle completely stops.
Step S102: and when the test vehicle is stopped by the preheating brake, circularly executing the step of adjusting the test speed of the test vehicle, and when the test speed reaches the target speed required by the brake system for preheating currently, carrying out the preheating brake on the test vehicle.
It should be noted that, when the test vehicle is preheated and braked, repeated braking is often required to complete preheating, and multiple times of braking is required to be performed on the test vehicle at this time. In a specific implementation process, the control device may repeatedly execute the preheating process after one preheating brake is completed until the preheating times reach the times that the brake preheating can be completed. For example, the test vehicle is braked to a stop at about a certain average deceleration at an initial speed of 56km/h, and is repeatedly performed 10 times, and then the vehicle is stopped by the full-force brake-activated antilock brake system at an initial speed of 72km/h, and is repeatedly performed 3 times. In the test process, if the test vehicle is stationary for more than a certain time, the brake system of the test vehicle needs to be preheated again. For example, when the test vehicle is stationary for more than 15 minutes, the brake-to-stop test is performed 3 times at a vehicle speed of 72km/h to warm up the brake system.
Step S103: and counting the braking times of the preheating braking of the test vehicle, and when the braking times reach the preset braking times, judging that the braking system finishes preheating and executing the step of confirming the basic functions of the test vehicle loaded with the pre-collision early warning system to obtain a basic function confirmation result.
The preset braking frequency is a preset braking frequency. And when the test vehicle completes the braking of the preset braking times, determining that the braking system of the test vehicle completes the preheating. In specific implementation, the control device can record the speed increasing process of the test vehicle and also record the braking-to-stop times of the test vehicle, and the recorded times are used as the braking times. And when the braking frequency reaches the preset braking frequency, judging that the braking system finishes preheating, and executing the subsequent step of confirming the basic function of the test vehicle loaded with the pre-collision early warning system to obtain a basic function confirmation result.
Wherein, before the step S101, the method further includes:
step S101': and acquiring the information of the tested road condition and the information of the tested environment.
When it needs to be explained, the testing traffic information refers to the traffic information of the road used in the testing. The test environment information refers to environment information where the test vehicle and the target vehicle are located during the test. Before testing the front collision early warning system of the test vehicle, whether the current test road condition information and the test environment information meet the test conditions needs to be determined. When the condition that the tested road condition information and the tested environment information both meet the condition is determined, an accurate test result can be obtained. For example, the traffic conditions in the tested traffic information are very poor, which may affect the measurement of the distance between the tested vehicle and the target vehicle, thereby resulting in an inaccurate test result. Similarly, when the environment in the test environment information is poor, the test environment is in a foggy day, at this time, there is not enough contrast between the target vehicle and the test environment, and the texture features of the target vehicle are difficult to identify, so that the test result is not accurate enough.
In specific implementation, the control device may collect the information about the tested road condition and the information about the tested environment through the information collection module. For example, the control device may collect video data of the test traffic information and the test environment information during the test, and analyze the collected video data to obtain the test traffic information and the test environment information.
Step S102': and comparing the test road condition information with a preset road condition, and comparing the test environment information with a preset environment condition.
It should be noted that the preset road condition is a preset condition for determining the test road condition. The preset environmental condition is a condition set in advance for determining the booklet number test environment. When the test road condition information and the test environment information are acquired, the test environment information and the test road condition information need to be judged, and the test of the front collision early warning system can be performed only when the test road condition information and the test environment information both meet the conditions. In a specific implementation process, the control device may compare the test traffic information with the preset traffic conditions to determine whether the test traffic information satisfies the traffic conditions tested by the front collision warning system. The control device can also compare the test environment information with a preset environment condition to determine whether the test environment information meets the environment condition of the front collision early warning system.
Step S103': and when the test road condition information meets the preset road condition and the test environment information meets the preset environment condition, executing the step of starting the test vehicle and increasing the test speed of the test vehicle.
It should be noted that, when the test road condition information satisfies the preset environmental condition and the test environmental information satisfies the preset environmental condition, it indicates that the current test road condition information and the test environmental information can accurately obtain the test result, and at this time, the control device may execute the relevant steps of starting the test vehicle and increasing the test speed of the test vehicle.
In this embodiment, the step S40 is followed by:
step S401: and acquiring vehicle state information when the test result of the front collision alarm test indicates that collision risk exists.
It should be noted that the test result refers to a result of whether or not there is a collision between the test vehicle and the target vehicle. When the test result shows that the collision risk exists, the driver needs to be warned so that the driver can change the current running state of the test vehicle. The vehicle state information refers to information of a current control state of the vehicle. For example, when the collision risk is determined, the front collision early warning system gives an alarm, the driver presses a brake pedal, the control device detects that the speed of the test vehicle is reduced, and the alarm is not needed at the moment.
In specific implementation, when the test result of the front collision alarm test indicates that the collision risk exists, the control device can monitor the test vehicle in real time to acquire the vehicle state information. For example, the control device may monitor the opening degree information of the brake pedal, the rotation information of the steering wheel, and the like of the test vehicle in real time to acquire the vehicle state information of the test vehicle.
Step S402: and matching the vehicle state information with a preset alarm-free case table, and closing an alarm function when the matching is successful.
It should be noted that the preset alarm-free case table is a table preset for judging whether the current vehicle state information of the test vehicle needs to be continuously alarmed or whether the current vehicle state information of the test vehicle needs to be alarmed. For example, when the front collision early warning system does not give an alarm, the alarm is not needed when the brake of the test vehicle is detected. In the specific implementation process, the control device can match the vehicle state information with the instances in the preset alarm-free instance table, and when the matching is successful, the control device indicates that the alarm is not needed to be performed on the current vehicle state information, and can actively turn off the alarm function.
