All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

According to the scheme, the message data with the fault information is generated and sent to the intelligent driving controller, the fault zone bit and the function degradation zone bit which are generated by the intelligent driving controller based on the message data corresponding to the message data with the fault information are obtained, the sending time of the message data with the fault information and the generating time of the fault zone bit and the function degradation zone bit are compared, and the test result is determined based on the comparison result.

Specifically, referring to fig. 1, the diagnostic automation test method disclosed in the embodiment of the present application includes:

Step S101: and generating and continuously transmitting message data containing fault information to the intelligent driving controller in a preset period.

In this scheme, the preset period is preset according to a rule, for example, the preset period may be an integer multiple of the message period, and the message period is generally a selected standard period (10 ms, 20ms, etc.). And the difference value between the preset period and the standard fault reporting period of the intelligent driving controller is smaller than a set value, and when the microcontroller unit in the intelligent driving controller detects that an error message (a message containing fault information) reaches the standard fault reporting period, a fault diagnosis code corresponding to the error message is reported, and a fault zone bit is generated. The difference between the preset period and the standard fault reporting period is smaller than a set value, the set value is an effective value which is preset, and when the difference exceeds the set value, the test process is invalid. In this scheme, the specific value of the preset period is determined according to the value of the standard fault reporting period. For example, the step may specifically be: generating and continuously transmitting message data containing fault information to the intelligent driving controller in a first preset period; or generating and continuously sending message data containing fault information to the intelligent driving controller in a second preset period; or generating and continuously transmitting message data containing fault information to the intelligent driving controller in a third preset period; the first preset period is smaller than a second preset period, the second preset period is a standard fault reporting period of the intelligent driving controller, and the third preset period is larger than the second preset period.

The diagnostic automatic test method disclosed by the embodiment of the application can be applied to an upper computer, wherein the upper computer is internally provided with a pre-stored test case, the fault types corresponding to different test cases are different, for example, the fault types can comprise signal error faults, counting error faults, checking error faults, overtime faults or data length error faults, if the fault type is the signal error faults, the wrong signal value is sent to a bus, and the wrong signal value is message data with fault information; if the fault type is a counting error fault, repeatedly sending a counting value at the previous moment to the bus, wherein the counting value at the previous moment is message data with fault information; if the fault type is a check error fault, directly sending a value calculated by standard check to a bus, wherein the value calculated by standard check is message data with fault information; if the fault type is overtime fault, stopping sending the message, wherein the time for stopping sending is the cycle number of the corresponding mark, and at the moment, the empty message is the message data with fault information. If the fault type is a data length error fault, the DLC (DATE LENGTH Code) data length Code is modified and then sent to the bus, and at the moment, the modified DLC data length Code is the message data with fault information. The upper computer can utilize tool compiling language to carry out loading management of test cases, in the scheme, when testing is carried out, a user can send a proper control instruction based on test requirements, a proper test case is selected and determined based on the control instruction, after the test case is determined, a fault sequence matched with the test case is generated, the fault sequence is used for prescribing a specific structure of message data containing fault information and a sending mode of the message data, and the fault sequence is sent to a test tool, so that the test tool generates and sends the message data containing the fault information to an intelligent driving controller. The test tool can generate message data with fault information according to the fault sequence, and send the message data to an intelligent driving controller to be tested based on a preset period set by the fault sequence, wherein the duration of each preset period can be set according to user requirements, for example, the duration can be an integral multiple of the message period, and the message period is generally 10ms, 20ms, 50ms and the like.

Step S102: acquiring the end time of the continuous transmission message data, and recording the end time as the first time;

in this step, when the transmission of the message data is completed, the end time is recorded as a first time, and for example, when the message data including the fault information for n periods is transmitted, the end time of the last period of the n periods is recorded as the first time.

In this scheme, referring to fig. 2, the intelligent driving controller includes a MCU (MicroControllerUnit) microcontroller unit and a SOC (System on Chip) system-level chip, the MCU microcontroller unit is connected to the ethernet switch through the ethernet, the SOC system-level chip is connected to the ethernet switch through the ethernet, after the MCU microcontroller unit obtains the message data with fault information, analyzes the message data with fault information, when detecting that the message data in a certain period is the message data with fault information, the counter starts counting, and when detecting that one message period is the message data with fault information, the counter counts up by 1, and when detecting that the message data with fault information continuously reaches n message periods, that is, when the count result reaches n, the MCU microcontroller unit first reports a fault diagnosis code corresponding to the message data with fault information, the fault diagnosis code can determine the fault diagnosis code corresponding to the message data with fault information through the diagnosis instrument, generate a fault flag bit, send the fault flag bit to the SOC system through the ethernet, and then the SOC system-level system is degraded, and the SOC system is degraded, and the relevant function is degraded, and the SOC system is degraded is then, and the function is degraded.

The upper computer can acquire the time of the function degradation zone bit generated by the intelligent driving controller directly or through a testing tool, and the time is recorded as third time.

Step S106: calculating comparison results of the first time, the second time and the third time;

After the first time, the second time and the third time are obtained, comparing the three based on a preset comparison strategy to obtain a comparison result, wherein the comparison result can be specifically calculated as the difference between the second time and the first time; a difference between the third time and the second time is calculated. And taking the difference between the second time and the first time and the difference between the third time and the second time as the comparison result of the first time, the second time and the third time.

Step S107: and outputting a test result matched with the comparison result.

In the scheme, test results matched with different comparison results are configured in advance, after the comparison results are determined, the test results are called and output based on the comparison results, and in order to facilitate the user to read the test results, the test results can be sent to a visual interface.

Specifically, in this step, if the difference between the second time and the first time is greater than the first preset duration, the failure flag bit test is indicated to be failed, and when the difference between the second time and the first time is less than or equal to the first preset duration and greater than zero, the failure report and the corresponding failure flag bit test are considered to be passed, and of course, when the value obtained by subtracting the first time from the second time is less than 0, the intelligent driving controller is considered to be set in advance and is also considered to be failed. And outputting a third test result for representing the failure of the function degradation zone bit test when the difference between the third time and the second time is larger than a second preset duration, and outputting a fourth test result for representing the passing of the function degradation zone bit test when the difference between the third time and the second time is smaller than or equal to the second preset duration and larger than zero, wherein, of course, when the value of the third time minus the second time is smaller than 0, the intelligent driving controller is considered to be set in advance and also to be the failure of the test. And then outputting the determined test result to a corresponding document so as to facilitate the visual check of the result by a tester. In the scheme, the first preset time length and the second preset time length are set to take the influence of inconsistent calculation tasks in the MCU and Ethernet message periods and loads on the bus into consideration, the test result can be more accurate by setting the first preset time length and the second preset time length, and the first preset time length and the second preset time length can be one message period length.

In the technical scheme disclosed in this embodiment, in order to ensure the reliability of the test result, the operation of step S101 may be repeated for multiple times, where the message data including the fault information is generated and sent to the intelligent driving controller in consecutive preset periods, and each time the step S101 is executed, the corresponding preset period has different values, and each corresponding preset period may represent an increasing relationship, and there is a preset time interval between two adjacent operations of executing step S101, so that the preset time interval needs to be set, so as to prevent unnecessary errors from occurring and affect the test accuracy. At this time, when the step S101 needs to be executed multiple times, in the above steps, generating and continuously presetting a period to send message data including fault information to the intelligent driving controller, including: generating for the X time and continuously transmitting message data containing fault information to the intelligent driving controller in a preset period; Judging whether the value of X is a preset secondary value, if not, controlling the value of X to be added with 1, and continuing to execute the action after waiting for a preset time interval: and generating and continuously presetting the number of times and sending the total number of times of the message data containing the fault information to the intelligent driving controller in the period of X, wherein the initial value of X is 1, and the preset number of times is the test number of times, namely, the total number of times of generating and continuously presetting the number of times and sending the message data containing the fault information to the intelligent driving controller in the period of X can be 2, 3, 4, 5, 6 or other times. For example, taking 3 times as an example, if each of the foregoing is regarded as a separate test procedure, the generating and continuously presetting the cycle sends message data including fault information to the intelligent driving controller, including: firstly generating and continuously transmitting message data containing fault information to an intelligent driving controller in a preset period; Generating for the second time and continuously transmitting message data containing fault information to the intelligent driving controller in a preset period; thirdly, generating and continuously transmitting message data containing fault information to the intelligent driving controller in a preset period; the number of the preset periods corresponding to the first time is smaller than the number of the preset periods corresponding to the second time, the preset period corresponding to the second time can be a standard fault reporting period of the intelligent driving controller, the preset period corresponding to the third time is larger than the preset period corresponding to the second time, and the first time, the second time and the third time correspond to the first time, the second time and the third time respectively and are generated for the first time, the second time and the third time, and the preset periods are continuously transmitted to the intelligent driving controller to form message data containing fault information. And sending message data containing fault information to the intelligent driving controller each time, wherein the total length of preset periods is different. In order to facilitate analysis of the test results, the adjacent two times of sending the message data containing the fault information to the intelligent driving controller are in continuous preset periods, and the total length of the preset period corresponding to the former time is smaller than that of the preset period corresponding to the latter time. For example, taking 3 times as an example, the first preset period is n-p message periods, the second preset period is n message periods, the third preset period is n+q message periods, and both p and q are greater than 0; n > p, and n > q. specifically, the length of the first corresponding preset period may be set to n-2 message periods, the length of the second corresponding preset period may be set to n message periods, the length of the third corresponding preset period may be set to n+2 message periods, n is set to several, signals representing that several message periods are continuously sent in the preset period, and n message periods may be set to be standard fault reporting periods of the intelligent driving controller, where, of course, the number of message periods included in each sent preset period may be set according to the user requirement, and the method is not limited to the forms of n-2, n, and n+2. After each execution of step S101, the steps of steps S102-S107 are executed once after the message data including the fault information is sent to the intelligent driving controller. the test mode can effectively detect the boundary of the fault reported by the intelligent driving controller, namely the earliest time and the latest time of the fault, grasp the calculation stability of the intelligent driving controller software and determine the fault tolerance interval of the follow-up fault calculation.
