Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar parameters or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
According to the method and the system for checking the abnormal functions of the whole vehicle, provided by the invention, after the test cases of the abnormal functions of the whole vehicle are determined, the whole vehicle reaction of the test cases of the abnormal functions of the whole vehicle is predicted instead of only predicting the reaction of relevant core components, so that the abnormal functions of the whole vehicle can be checked more comprehensively.
In order to better understand the technical scheme and technical effect of the present invention, the following detailed description will be made on specific embodiments with reference to a flow diagram. As shown in fig. 1, a flowchart of a method for checking abnormal functions of a finished automobile according to an embodiment of the present invention is provided, where the method includes the following steps:
and step S01, collecting the abnormal functions of the whole vehicle.
In the embodiment of the invention, the abnormal functions of the whole vehicle can be manually collected, for example, the abnormal functions of the whole vehicle fed back by the vehicle owner and the maintenance part are summarized to obtain the abnormal functions of the whole vehicle. In addition, the abnormal function of the entire vehicle may also be collected by a specific processor, which is not limited herein.
Wherein, whole car unusual function can include: limp, collision, low insulation of the whole vehicle, high-voltage safety, power-off overtime, over-high temperature of the battery, complete discharge of the battery and an abnormal prompting lamp.
In a specific embodiment, the abnormal functions of the whole vehicle include any one or more of the following: ABS fault, low vehicle insulation, and vehicle collision protection fault. When the automobile is a pure electric automobile, the abnormal functions of the whole automobile further comprise any one or more of the following functions: the misoperation touches high voltage, the primary thermal instability of the power battery and the complete discharge of the power battery.

Step S02, determining the checking mode of each vehicle abnormal function, wherein the checking mode comprises the following steps: manual operation, software simulation, or vehicle test verification.
In this embodiment, after various vehicle abnormal functions are collected, the inspection mode of each vehicle abnormal function is determined, and since the test cases need to be detected by a specific inspection mode and the test cases required by different inspection modes are different, the inspection mode of each vehicle abnormal function needs to be determined first, and then the test case of each vehicle abnormal function needs to be determined.
Considering the problems of implementability, efficiency and cost, different checking modes can be selected for different abnormal functions of the whole vehicle, and the checking modes can include the following three modes: manual operation, software simulation, or vehicle test verification. The abnormal function of the whole vehicle is caused to be the simplest and most convenient in a manual operation mode, and the cost is low, so that manual operation can be adopted preferentially; the convenience of software simulation is slightly worse than that of manual operation, but the cost is also lower: destructive tests are not needed, so that a mode of priority software simulation of manual operation cannot be adopted; if the abnormal function of a certain whole vehicle cannot be simulated by manual operation and software simulation, a whole vehicle test verification mode is adopted, such as a collision test, a wading test and the like, and the mode belongs to a destructive test, so that the period is long and the cost is high.

And step S23, if not, judging whether the abnormal function of the whole vehicle can be formed through a whole vehicle test verification mode, if so, checking by adopting the whole vehicle test verification mode.
Specifically, (1) manual operation: for the failure of system hardware, some faults can be artificially produced through simple operation, the whole vehicle reaction is checked and confirmed, for example, a connector of a certain sensor is pulled out, and signal abnormity caused by the damage of the sensor is artificially produced; (2) software simulation: for some test cases which need to consume a large amount of test resources and time or have certain dangerousness in the test, test conditions can be simulated through relevant software (such as a vehicle control unit VCU, a motor controller PCU and a battery management system LBC), and the result of the vehicle after the vehicle executes relevant strategies can be checked and confirmed, for example, the battery management system BMS simulates that the temperature of a battery cell is too high; (3) and (3) vehicle test verification: and developing related tests to restore the abnormal state of the whole vehicle, predicting possible reactions of the whole vehicle, executing corresponding strategies, checking and confirming the difference between the actual result and the expected result of the whole vehicle, and verifying whether the insulation of the whole vehicle reaches the standard or not through collision and wading tests.
And step S03, determining the test cases of the abnormal functions of the whole vehicles according to the abnormal functions of the whole vehicles and the checking mode of the abnormal functions of the whole vehicles.
In this embodiment, after the checking mode of the abnormal function of each whole vehicle is determined, the corresponding test case is determined according to the characteristic of the abnormal function of each whole vehicle. Specifically, the following steps may be included:
1. determining possible objects of abnormal functions of the whole vehicle; 2. determining the most critical parts through experiments; 3. analyzing related parts of each key part and the influence on the whole vehicle function; 4. the test is carried out to verify; 5. making a decision list of the influence of each verified key part on the relevant parts and the whole vehicle function; 6. and taking each case of the judgment table as a basis to design a test case. The tests are shown in Table 1, for example.
TABLE 1 test case
And step S04, predicting the whole vehicle reaction of the test case of the abnormal function of each whole vehicle.
In this embodiment, the overall vehicle reaction of the test case may be predicted according to the determination table provided in step S03, for example, when a certain sensor is unplugged or an error signal is considered to be input, the reaction that the relevant control unit should make may include a correct reaction and an error reaction, where the error reaction may be further divided into a serious error reaction, a non-critical error and the like, which is not limited herein. The overall vehicle response can be shown in table 2.
TABLE 2 complete vehicle reaction
And step S05, testing by using the test cases of the abnormal functions of the whole vehicle, comparing the test result with the predicted whole vehicle reaction, and if the comparison result is consistent, checking the abnormal functions of the whole vehicle.
In the embodiment, the actual result is compared with the expected result to check the abnormal function of the whole vehicle, and the targeted improvement is facilitated, such as taking remedial measures for threatening the personal safety.
Further, as shown in fig. 3, another flowchart of the method for checking the abnormal function of the entire vehicle according to the embodiment of the present invention is provided, and the method may further include the following steps:
step S36, if the test result is consistent with the predicted vehicle reaction, the vehicle abnormal function verification is completed;
and step S37, if the test result is inconsistent with the predicted complete vehicle reaction, modifying the complete vehicle function strategy until the test result is consistent with the predicted complete vehicle reaction.

The method has the advantages that the whole vehicle reaction time of the test case of each whole vehicle abnormal function is predicted, whether the reaction of related core components is correct or not is considered, and the reaction of the whole vehicle is considered, so that the problems that in the prior art, the whole vehicle abnormal function checking method is incomplete, and the whole abnormal function checking process cannot be fully verified can be effectively solved. In addition, the checking modes of the abnormal functions of the whole vehicle include three modes, so that a most appropriate checking mode can be selected from the three checking modes, for example, the simplest or lowest-cost checking mode capable of checking the abnormal functions of the whole vehicle is adopted: the convenience degree of manual operation is more than the convenience degree of software simulation is more than the convenience degree of test verification of the whole vehicle.
