step S101, acquiring a preset whole vehicle calibration and debugging strategy.

The whole vehicle calibration and debugging strategy comprises any one or more of an misoperation response strategy and a normal operation response strategy.

In the development process of the electric automobile, the calibration and debugging of the automobile are related to the normal use of the automobile, and in the debugging stage, in order to ensure the debugging effect, a whole automobile calibration and debugging strategy is preset, wherein the strategy refers to a debugging scheme and comprises various operation actions, such as a gear shifting device, an accelerator pedal and the like, so that the whole automobile is debugged through the operation actions in the whole automobile calibration and debugging strategy. In the debugging process of gear control, multiple types of data such as vehicle running data generated by the debugging actions of a whole vehicle controller and a debugging user are required to be comprehensively analyzed, so that the triggering action under each strategy is generated through the whole vehicle calibration and debugging strategy.

In the control process of the electronic gear, there are two general cases, the first is electronic gear control executed under normal operation, that is, electronic gear control under the condition of no misoperation, that is, the electronic gear control corresponds to a normal operation response strategy, and the gear control under the normal condition is debugged through the operation action in the corresponding normal operation strategy; the second is electronic gear control executed under misoperation, that is, electronic gear control under the influence of misoperation of a user corresponds to an misoperation response strategy, and gear control under the misoperation condition is debugged through operation actions in the misoperation response strategy so as to adapt to various operations in the actual running process of the whole vehicle.

Step S102, based on the whole vehicle calibration and debugging strategy, acquiring a designated gear signal of the self-return gear under the triggering action corresponding to the calibration and debugging strategy and real-time operation data of the designated vehicle, and sending the designated gear signal and the designated vehicle real-time operation data to the whole vehicle controller through CAN communication.

Specifically, in one embodiment of the present disclosure, based on the entire vehicle calibration and debug policy, a specified gear signal of the self-return gear under a trigger action corresponding to the calibration and debug policy and specified vehicle real-time operation data are obtained. And determining a debugging action corresponding to the whole vehicle calibration and debugging strategy through the whole vehicle calibration and debugging strategy. When the whole vehicle calibration debugging strategy is a normal operation response strategy, the locking button debugging action, the accelerator pedal debugging action, the brake pedal debugging action and the gear selector debugging action corresponding to the debugging actions all meet the normal gear shifting operation requirements, and the whole vehicle runs under the triggering of the debugging actions corresponding to the normal gear shifting operation. The designated gear signals acquired by the self-return gear and the designated vehicle real-time running data corresponding to the whole vehicle under the drive of the debugging action are used for acquiring the designated vehicle real-time running data.

When the whole vehicle calibration debugging strategy is a misoperation response strategy, the locking button debugging action, the accelerator pedal debugging action, the brake pedal debugging action and the gear selector debugging action corresponding to the debugging actions comprise at least one misoperation, such as that the locking button is not pressed, the gear selector is shifted to generate smaller displacement and the like. And under the triggering of the debugging action corresponding to the misoperation, the whole vehicle runs. The designated gear signals acquired by the self-return gear and the designated vehicle real-time running data corresponding to the whole vehicle under the drive of the debugging action are used for acquiring the designated vehicle real-time running data.

For example, the first position identification signal, the second position identification signal, the third position identification signal, the fourth position identification signal and the fifth position identification signal are set to be gsm_levepost=2, gsm_levepost=1, gsm_levepost=0, gsm_levepost=3 and gsm_levepost=4, the gear corresponding to gsm_levepost=0 is the D gear, the corresponding positions pushed forward are gsm_levepost=1 and gsm_levepost=2 in order, the corresponding gear is the R gear, the corresponding positions pushed backward are gsm_levepost=3 and gsm_levepost=4 in order, and the corresponding gear is the D gear.

That is, the current bar position signal is a plurality of position signals, the gear position signal corresponding to the debugging time is taken as the initial bar position signal, after the debugging time, the debugging process is started, that is, the position signal after the initial bar position signal is taken as the real-time bar position signal, for example, the uploading frequency of the position signal of the gear is once per second, and if the bar position is unchanged within three seconds, the bar position signals corresponding to the three seconds are the same.

First, a gear shift condition judgment logic is executed, and fig. 2 is a schematic diagram of a gear shift condition judgment logic provided in the embodiment of the present disclosure, as shown in fig. 2, in the case of a READY state of the whole vehicle, whether a gear shift condition is provided is judged by a gear failure state signal and a lock button state signal in a gear signal.
