Generate statistical data of error causes of the current test route according to the current test route and the first associative array, and store it in the student account data; The driving test simulation test is retriggered, and an error reason is prompted. 9. a kind of driving test simulation method based on VR driving simulator according to claim 8, is characterized in that, if described, if do not meet, then retrigger driving test simulation test, and the step of prompting error reason also comprises: According to the first associative array and the second associative array, it is determined that the test results of the same current test route and the same current traffic flow module difficulty level are similar test results; whether the number of similar test results is greater than expected set quantity; If so, obtaining the latest preset number of similar test results at the test time as the current test results, and generating a pass rate according to a plurality of the current test results; Obtain the difficulty coefficient edited corresponding to the difficulty level of the traffic flow module; Obtain a plurality of difficulty levels of the current traffic flow module and a plurality of corresponding pass rates according to the current examination route; Obtain the current difficulty coefficient according to the difficulty level of the current traffic flow module, and obtain the actual pass rate through a plurality of the current difficulty coefficients and a plurality of corresponding pass rates; judging whether the actual pass rate is higher than the preset pass rate; If yes, send the student account, the actual passing rate and the error reason statistical data corresponding to the current route to the coach account. 10. A driving test simulation system based on a VR driving simulator, characterized in that, a driving test simulation method based on a VR driving simulator as described in any one of claims 1-8; The test simulation system includes a server and multiple VR driving simulators, the servers are connected to multiple VR driving simulators respectively, and the server is connected to the Internet.
