Description

Bad driving habit judging and correcting method and system Technical Field The invention relates to the technical field of vehicle driving, in particular to a bad driving habit judging and correcting method and system. Background The clutch half-linkage is also called as a half-clutch state, namely after a driver presses a clutch pedal, the pressure of a clutch pressure plate is gradually reduced, so that the engine flywheel and an input shaft of the gearbox are in a sliding friction state of 'rotating and sliding', at the moment, the power of the engine and the gearbox is partially connected, and a rotating speed difference exists between the input shaft and an output shaft. Two-gear starting refers to the operation of skipping the first gear and accelerating the vehicle from a stationary state directly from the second gear when the vehicle starts, and two-gear starting refers to the operation of the engine to drag the stationary vehicle with a higher rotational speed, which results in a longer time for the clutch to be in a semi-interlocked state to allow the vehicle to move. When the vehicle is started, the high-speed rotation of the engine can cause abnormal abrasion of key parts such as a cylinder wall, a bearing bush and the like. When a driver drives a vehicle, the bad driving behavior of the high-speed operation of the engine during the half-linkage of the clutch, the second gear starting or the starting can cause the ablation of the clutch and the damage of the engine, and the service life of the vehicle is influenced. In the prior art, correction and improvement of bad driving habits of a driver who works at a high engine speed when a clutch is in half-linkage, second gear starting or starting cannot be performed. Disclosure of Invention The invention aims to overcome the defect that the prior art cannot correct and improve the bad driving habit of a driver working at a high rotating speed of an engine when the clutch is in half-linkage, the second gear is started or started, and provides a method and a system for judging and correcting the bad driving habit. In order to solve the technical problems, the invention adopts the following technical scheme: the method for judging and correcting bad driving habits comprises the following steps: Judging whether the driver has bad driving behaviors or not in a first period, counting the times of the bad driving behaviors of the driver in the first period, and reminding the driver when the bad driving behaviors of the driver occur; Step two, judging whether the number of times of bad driving behaviors in the step one is larger than a first preset value, if so, performing the step one, otherwise, performing the step three; Judging whether the driver has bad driving behaviors or not in a second period, counting the times of the bad driving behaviors of the driver in the second period, and not reminding the driver when the bad driving behaviors of the driver occur; Judging whether the number of bad driving behaviors in the third step is larger than a second preset value, if so, performing the first step, otherwise, performing the fifth step; and fifthly, outputting a corrected result of the bad driving habit of the driver. In the third and fourth steps of the scheme, counting the number of times of bad driving behaviors of the driver in the second period and judging whether the number of times of bad driving behaviors is larger than a second preset value are performed synchronously, and when the number of times of bad driving behaviors in the second period is accumulated to exceed the second preset value, the first step is performed. The method for judging and correcting the bad driving habit not only can prompt the driver in time after judging that the bad driving behavior of the driver occurs, and prompt the driver to correct the bad driving behavior, but also can set a monitoring period to judge whether the driver has improved the bad driving habit, thereby being beneficial to helping the driver to correct the bad driving habit of the driver when driving, leading the driver to have a good driving habit, improving the safety of the driver in the driving process and being beneficial to prolonging the service life of the vehicle. Preferably, determining whether the driver has poor driving behavior includes: Judging whether the time of clutch half-linkage is normal, judging whether the vehicle starts in a second gear and judging whether the engine speed is overlarge when the vehicle starts. When the occurrence of the three types of bad driving behaviors is judged and the occurrence times are counted, the statistics can be performed separately or together. The preset values of the times of each bad driving behavior are different in the separate statistics, and the preset values of the times of the bad driving behavior are the sum of the times of the three behaviors when the three behaviors are counted together. The calculation modes of the first period and the
