In addition, the flows may include more or fewer operations, and the operations may be performed sequentially or in parallel. It should be noted that, the descriptions of "first" and "second" herein are used to distinguish different messages, devices, modules, etc., and do not represent a sequence, and are not limited to the "first" and the "second" being different types.

As described in the background art, the super capacitor can provide stronger power for the electric automobile in some cases, and can recover the power of the electric automobile in the braking process of the electric automobile, but the super capacitor is only arranged inside the electric automobile at present.

Firstly, because the super capacitor has a certain volume, when designing an electric vehicle comprising the super capacitor, a certain space is reserved for the super capacitor, and the design complexity is increased.

The inventor envisions whether the super capacitor can be used as a mounting component to be mounted outside the electric automobile, so that the complexity of the electric automobile can be reduced, the requirement of a user for mounting the super capacitor can be met, and the super capacitor is easy to repair and replace under the condition that the super capacitor is damaged.

Further, it is not cost-effective to think that the tail of the animal rotates to improve the stability of walking and running during the running of the animal, and a single dead reuse is used to add the tail to the car to improve the driving stability of the car, and the super capacitor has a certain weight, so the inventor thinks whether the super capacitor can be mounted at the tail of the electric car, and the super capacitor is arranged in a certain structure for improving the stability of the electric car during the running of the electric car.

In order to achieve the above-mentioned assumption of the inventor, the inventor proposes a technical solution of an embodiment of the present application, and in the embodiment of the present application, an electric automobile control system is provided, which is applied to an electric automobile, and includes: a control module and an auxiliary power structure; the auxiliary power structure is detachably connected with the control module and the battery module of the electric automobile; the auxiliary power structure comprises a super capacitor and a rotating mechanism, wherein the super capacitor is arranged on the rotating mechanism; the control module is used for controlling the battery module to charge the super capacitor when the electric automobile is in the first electricity condition; when the electric automobile is in the second electricity utilization condition, the super capacitor is controlled to discharge to the power mechanism; and controlling the rotating mechanism to drive the super capacitor to rotate based on the running parameters of the electric automobile. According to the embodiment of the application, the auxiliary power structure comprising the super capacitor is connected with the electric automobile in a detachable mode, a personalized mounting mode can be provided for a user, and the auxiliary power structure can be controlled to rotate to a corresponding target rotation mode based on different vehicle running parameters, so that the running stability of the electric automobile is improved.

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application.

Fig. 1 shows a schematic structural diagram of an embodiment of an electric vehicle control system provided in the present application, as shown in fig. 1, the system includes: a control module 101 and an auxiliary power structure 102;

the auxiliary power structure 102 comprises a super capacitor 1021 and a rotating mechanism 1022, wherein the super capacitor 1021 is arranged on the rotating mechanism 103;

It should be noted that, the specific values corresponding to the first electricity consumption condition and the second electricity consumption condition on different electric vehicles are different, so that the first electricity consumption condition and the second electricity consumption condition can be flexibly set according to the actual situation of the electric vehicles.

Alternatively, the target rotation mode corresponding to the auxiliary power structure may be determined first based on the vehicle running parameter, and then the auxiliary power structure may be controlled to rotate to the corresponding target mode.

The target mode may be rotation around a fixed point in a preset rotation mode, or movement of the auxiliary power structure to a preset position, or the like.

For example, in a state that the electric automobile runs stably, the control module can control the auxiliary power structure to extend towards the direction perpendicular to the tail of the electric automobile so as to control the moment of inertia of the automobile and further stabilize the automobile.

Optionally, after the rotation mode prediction model is obtained, the vehicle running test parameters are input into the rotation mode prediction model, so that the test rotation modes, corresponding to the auxiliary power structures predicted by the vehicle running test parameters in the position prediction model, are obtained.

The correction process of the rotation mode test model can be realized as follows: the method comprises the steps of establishing a virtual running environment of the electric automobile, wherein the virtual running environment can simulate the real running environment of the electric automobile, so that the corresponding vehicle running condition of an auxiliary power structure in the electric automobile under the condition of a certain rotation mode is obtained, and the virtual running environment can be based on the corresponding vehicle running actual parameters of the vehicle running. Taking a single auxiliary power structure as an example, an electric vehicle is driven by a normal road condition to turn, an obtained model output instruction is that the auxiliary power structure is required to rotate 30 degrees in a bending direction, the auxiliary power structure in the electric vehicle is controlled to rotate in the mode, the turning process of the electric vehicle is further simulated in a virtual running environment, in the turning process, the air pressure of the wheels at the outer side of the turning of the vehicle is found to be still at a higher level, and the tail flicking feeling is strong, so that the predicted turning mode is unsuitable, and the auxiliary power structure is required to rotate in the bending direction by a larger angle.

The rotation mode prediction model is input and corrected based on the actual vehicle running parameters, so that the rotation mode output next time is more accurate.

It will be appreciated that the above described corrective action may need to be performed multiple times to refine the predictive model.
