In this embodiment, the advanced driving assistance system includes a control module and millimeter wave radar, ultrasonic wave, and camera. The data acquisition unit outputs the acquired index parameters to the testing device in a CAN signal mode.

The test apparatus in the first embodiment of the present application is described below with reference to fig. 6.

As shown in fig. 6, in this embodiment, a test device 600 is connected to a data acquisition unit through a CAN bus, and the test device 600 includes a CAN signal transceiver 601, an arithmetic processing unit 602, a storage unit 603, an acousto-optic unit 604, and a display unit 605. The CAN signal transceiver 601 receives a CAN bus signal carrying a target performance index parameter, extracts the target performance index parameter from the CAN bus signal, and sends the target performance index parameter to the operation processing unit 602 and the storage unit 603, respectively. The CAN signal transceiver unit 601 comprises a preprocessing module, the preprocessing module filters a large number of status signals which are not changed repeatedly, the preprocessing module stores each frame of received message in real time, and meanwhile, the data content of the same frame ID of the next frame is compared, if the data content of the same frame ID of the next frame is the same, the data content of the same frame ID of the next frame is filtered, and otherwise, the data content of the same frame ID of the next frame is normally output to the test operation module.

The storage unit 603 may use a Secure Digital (SD) card to store received data while storing a time stamp of performance index parameter collection, and store a log of operations and a log of failures generated during the test process, so as to develop an analysis of the failures. The arithmetic processing unit 602 detects the operation state of the advanced driving assistance system based on the target performance parameter, and outputs the detection result through the acousto-optic unit 604 and the display unit 605. Specifically, the operation processing unit 602 is burned into the system by self-grinding software, and CAN identify the standard CAN Database (DBC) protocol, and analyze the actual values of all the performance parameters according to the DBC protocol. And according to the limiting range of each performance parameter, judging, analyzing and testing results by oneself. If the failure item is detected, the test log is automatically recorded, and the test log is fed back to the acousto-optic unit according to a set program, so that the state of the indicator lamp and the state of the buzzer are changed, and a tester can timely grasp the test state of the product.

The unit can be self-adaptive to various DBC protocol items, so that portability and expandability are good. At present, each vehicle-mounted item can be directly put into use.

The test system can be used for monitoring the actual running state of the advanced driving assistance system under various severe test conditions in real time and continuously, recording the performance index parameters at any moment in running, and not only can control the performance of the advanced driving assistance system on a real vehicle in advance, but also can provide data support for the sensor selection of the advanced driving assistance system.

Specifically, the test device 600 is implemented by a development board based on an STM32 micro control unit (Microcontroller Unit, MCU), and the CAN signal transceiver unit 601 on the development board is configured with a plurality of CAN signal transceiver modules, so that the development board has the capability of simultaneously transceiving multiple CAN signals. At present, independent CAN equipment is adopted for receiving and transmitting CAN signals, and meanwhile, an industrial personal computer is required to be matched with an upper computer for testing, so that the cost is high, and the laboratory is not facilitated to deploy a test bench in a large scale. The embodiment is based on secondary development of the CAN module on the development board, CAN save CAN equipment and an industrial personal computer, supports multipath CAN signal processing, has the advantage of light weight of the testing device and saves equipment cost.

VD1 and VD2 are voltage input ports, the resistances of the resistor R1 and the resistor R2 are the same, C1 is a capacitor, and the capacities of the resistor R1 and the resistor R2 and C1 can be determined according to the actual measurement voltage range. The first voltage acquisition module and the second voltage acquisition module are isolated through a resistor R3, and the resistance value of the resistor R3 can be 50mohm. The two detection mutual backups can be realized, and whether the power supply has a short circuit fault can be detected through the voltage difference. The MCU detects the collected node voltage through an Analog-to-Digital Converter (ADC) port, if the detected voltage exceeds the ADC detection voltage range of the MCU, the voltage can be reduced through voltage division, and then the collected voltage signal is sent to the MCU.

The device temperature is detected by two different acquisition modes, one is detected through an ADC port.

The temperature-sensitive resistor R4 is arranged on the periphery of the integrated circuit to be detected, then the corresponding temperature is calculated through the variation of the resistance value,

Another method of acquisition is to monitor the temperature by acquiring temperature data monitored by the integrated circuit itself. The MCU can monitor the temperature of the core by itself, and can read out the temperature data through the corresponding function, and then output the temperature data to the DBC.

Two detection mutual backups can be realized in the same way through two temperature acquisition modes, and the detection accuracy is improved.

The communication function parameter acquisition of the radar sensor can be realized through a function acquisition module. The function acquisition module is developed by using an on-board safety communication (Secure Onboard Communication, secOC) module, and the accuracy and the instantaneity of the radar CAN message transmission are detected by adding RollingCounter and Checksum information to the traditional message. If the bilateral count is inconsistent in the radar message transmission or the bus data is not abnormal, a radar data error is reported, and the MCU outputs a radar error frame or how many frames have no radar data error to the DBC, so that the function monitoring is used for radar CAN data monitoring.

The collection of the operation state of the advanced driving assistance system can be realized through a state monitoring module, and the state monitoring module is realized through a serial peripheral interface (SERIAL PRIPHERAL ITERIC, SPI) channel between the MCU and the advanced driving assistance system. According to various well-defined fault states, if an advanced driving assistance system fails, various state bits are reported, and the MCU reads the corresponding state through the SPI and outputs the state as a CAN signal.

The test system of the embodiment realizes the capability of a set of test kits to test a plurality of products. According to different projects, the detection scheme can be self-adapted only by importing corresponding DBC protocols, the expandability of different detection requirements is realized, the cost is low, the maintenance is easy, and the method can be applied to various tests in batches.
