the preset corresponding relation data of each piece of vehicle state data information comprises:
(1) data of correspondence between the acceleration limit and the vehicle speed, as shown in fig. 3;
the basis for making the corresponding relation data of the acceleration limit value and the vehicle speed is as follows: if the acceleration of the vehicle is too large, namely the vehicle is accelerated suddenly, the oil consumption of the vehicle is increased sharply at the moment, and the energy conservation and emission reduction are not facilitated, so that the corresponding relation between the acceleration limit value and the vehicle speed is established according to the acceleration limit value, and if the acceleration of the vehicle is below the corresponding acceleration limit value under the current vehicle speed, the oil consumption of the vehicle is stable in the region, and the energy conservation and emission reduction are realized;

the formulation basis of the data of the corresponding relation between the maximum vehicle speed and the water temperature is as follows: when the vehicle is started in a cold state, the water temperature is generally low, particularly in winter, under the condition, if the oil consumption and the abrasion are serious when the vehicle runs rapidly, corresponding relation data of the maximum vehicle speed allowed by the vehicle and the water temperature is formulated according to the situation, the vehicle runs at the corresponding maximum vehicle speed under the current water temperature, the energy is saved, the emission is reduced, and the service life of the vehicle is prolonged;

the basis for formulating the data of the corresponding relationship between the vehicle distance and the maximum vehicle speed limit value and the minimum vehicle speed limit value respectively is as follows: within a certain distance, if the vehicle speed is too high, the braking distance is increased, traffic accidents are easily caused, and the safety driving is not facilitated; if the vehicle speed is too low, the engine can work in an area with relatively high fuel consumption rate, so that the fuel consumption and the emission of the vehicle are increased, and therefore, the maximum vehicle speed limit value and the minimum vehicle speed limit value under the current vehicle distance are set according to the situation, and the vehicle can run in the corresponding maximum vehicle speed limit value and the minimum vehicle speed limit value under the current vehicle distance, so that the driving safety can be ensured, the engine can work in an area with high heat efficiency, and the effects of energy conservation and emission reduction can be achieved;

(2) when the data processing module receives the accelerator pedal opening data information and the vehicle speed data information, the accelerator pedal opening data information is processed and converted into an acceleration signal, as shown in fig. 3, the acceleration signal is compared with corresponding relation data of a built-in preset acceleration limit value and the vehicle speed, if the situation that the acceleration value of the current vehicle is more than twice greater than the acceleration limit corresponding to the current vehicle speed (the acceleration limit value can be set according to the vehicle state) continuously occurs in a preset time period, the driving habit of the driver is judged to be poor, and therefore the data processing module sends a prompt instruction of 'do not shake';
(3) when the data processing module receives the water temperature data information and the vehicle speed data information of the engine, as shown in fig. 4, the data processing module compares the data with corresponding relation data of the built-in preset highest vehicle speed and water temperature, if the current vehicle speed value is larger than the highest vehicle speed corresponding to the current water temperature, the fact that the vehicle running oil consumption and abrasion are serious under the current vehicle speed is judged, and therefore the data processing module sends a speed reduction prompting instruction;
(4) when the data processing module receives the vehicle distance data information and the vehicle speed data information, as shown in fig. 5, the data processing module compares the vehicle distance data information with corresponding relationship data of a preset vehicle distance with a maximum vehicle speed limit value and a minimum vehicle speed limit value respectively, if the current vehicle speed value is larger than the maximum vehicle speed limit value corresponding to the current vehicle distance, it is judged that the current vehicle speed is faster, the braking distance is increased, traffic accidents are easily caused, and safety driving is not facilitated, so the data processing module sends a prompt instruction of 'please slow down'; if the current vehicle speed value is smaller than the minimum vehicle speed limit value corresponding to the current vehicle distance, judging that the current vehicle speed is low, and the engine works in an area with relatively high fuel consumption rate at the moment to cause the increase of the fuel consumption and emission of the vehicle, so that the data processing module sends an acceleration prompting instruction;
(5) when the vehicle is in the manual gear control mode, the data processing module receives gear state data information and compares the gear state data information with a gear corresponding to the current vehicle speed under a built-in gear strategy, as shown in fig. 6, if the current gear of the vehicle is lower than the gear corresponding to the current vehicle speed, the data processing module sends a prompt instruction of 'please upshift'; if the current gear of the vehicle is higher than the gear corresponding to the current vehicle speed, the data processing module sends a gear descending prompting instruction to reduce the oil consumption and emission of the vehicle and improve the driving experience of a driver;

and the data processing module sends the sent instruction information to the information judgment module through a CAN line of the whole vehicle for further analysis and processing.
