in this embodiment, the specific area includes sensitive areas such as ports and docks for automobiles to smuggle, but the present invention is not limited to the above areas as the specific area, and can be set according to actual requirements;
step 2.2, checking the vehicle operation state, and whether batch vehicles are off-line simultaneously;
the vehicle offline judgment criteria in this embodiment are:
stopping sending the vehicle-mounted T-BOX data, enabling the duration time to be longer than 30s, enabling the first off-line time in the batch of vehicles to be the starting time TS and the last off-line time to be the ending time TE, and when the difference value between the TE and the TS is smaller than 1min, considering that the batch of vehicles are off-line simultaneously;
if the vehicles are simultaneously off-line, it is deemed necessary to initiate the electronic fence function for each vehicle located in the particular area.
Preferably, in another embodiment, the batch of vehicles is further judged;
and 2.3, if the speed per hour of each vehicle in the batch of vehicles before offline is less than 1km/h and the SOC distribution interval of the battery is [20%,30% ], determining that the electronic fence function needs to be started for each vehicle in a specific area. It should be noted that the speed per hour and the battery SOC may be set according to actual needs, and the vehicle smuggling involves transportation, and from the viewpoint of safety, the battery SOC is controlled to a low SOC level when the electric vehicle is transported.
Preferably, in another embodiment, the vehicle in step 2 is further judged:
and 2.4, checking the recurrence condition of the T-BOX data, if the vehicle-mounted T-BOX recurrence data of any vehicle in the batch of vehicles is not received within 3min, or the T-BOX recurrence data of one or more vehicles is received within 3min, the vehicle speed is below 1km/h, the distribution interval of the SOC of the battery is [20%,30% ], judging that the vehicles have the risk of smuggling, starting an electronic fence function for each vehicle in a specific area, and ending the execution.
And S3, acquiring the fault level and the running track of the vehicle, and judging whether to start the electronic fence function of the vehicle according to the fault level and the running track of the vehicle.

From the vehicle fault level specified by the national standard, the fault drivers of the level 0 and the level 1 can not process the fault, and the situation that the vehicle operation area exceeds the preset area due to the fact that the driver changes the vehicle running track to a nearby vehicle maintenance station can not occur.
The 3-level fault vehicle cannot continue to run, the driver can request rescue, and the judgment processing for starting the electronic fence function of the vehicle can be omitted in the case.
S3.1, if the vehicle fault level is a level 2 fault, executing the step S3.2; if the vehicle fault level is less than the level 2 fault, namely the level 0 fault and the level 1 fault, executing the step S3.3;

and when the vehicle running track direction is consistent with the position of the vehicle maintenance station outside the nearby preset area, judging that the vehicle needs to be maintained nearby, and comprehensively analyzing the vehicle mileage, the battery SOC state and the vehicle running track direction.
S3.3 calculating the remaining mileage S of the vehicle according to the current accumulated mileage of the vehicle and the SOC of the battery NR Will S NR Distance S from complementary energy AE Comparing; when S is NR Distance S from complementary energy AE If the difference value is greater than the set distance and the vehicle running track is inconsistent with the direction of the charging station or the battery replacement station, the electronic fence function of the vehicle needs to be started;
for the 0-level and 1-level and 2-level fault vehicles with unreasonable vehicle running tracks and unreasonable maintenance station track directions, the possible situation that whether the vehicle operation area exceeds the preset area due to the energy supplementing requirement or not needs to be considered.
Generally, the remaining mileage S is displayed on the vehicle meter NR For identifying the energy supplementing requirement, the national standard GB/T32960.3-2015 does not define the remaining mileage, and the vehicle-mounted T-BOX does not forward the field, so the vehicle remaining mileage estimated by the vehicle end cannot be directly used, and the vehicle mileage and battery SOC state field defined by GB/T32960.3-2015 are combined to convert and estimate the remaining mileage S NR . The method comprises the following steps:
accumulated mileage S according to vehicle history HT And the variation delta SOC of the battery SOC in the driving process can be counted and analyzed to obtain the average daily mileage S of the vehicle DA And the whole vehicle energy consumption W, the calculation formula is as follows, wherein, the delta SOC isAnd the starting SOC is the first frame SOC value read after the vehicle is electrified, and the ending SOC is the SOC value at the previous moment after the vehicle is electrified.
S DA = vehicle accumulated mileage S HT Number of days in operation, unit km/d
W = battery discharge energy/vehicle daily mileage SDA, unit kWh/100km
Wherein, the battery discharge energy is rated energy Δ SOC;
combined with the current accumulated mileage S of the vehicle NT And battery SOC according to the formula: rated energy SOC/W- (S) NT -S HT ) Can estimate the remaining mileage S of the vehicle NR 。
Calculating the energy compensation distance S of the vehicle AE (ii) a Comparing the remaining mileage S of the vehicle NR Distance S from complementary energy AE If the difference value between the two is less than 30km and the direction of the vehicle running track is consistent with the direction of the charging station or the power changing station, the driver is considered to have the energy supplementing requirement, and the electronic fence function of the vehicle is not started; and if the difference value between the two is more than or equal to 30km and the vehicle running track direction is inconsistent with the direction of the charging station or the power changing station, starting the electronic fence function of the vehicle.
