Next, a power swapping station 100 and its off-station environment according to an embodiment of the present application will be described with reference to fig. 1.

Fig. 1 is a schematic diagram of a power swapping station 100 and an environment outside the power swapping station according to an embodiment of the present application. As shown in fig. 1, a battery swapping area 106 is disposed in the battery swapping station 100, where the battery swapping area 106 is used for the vehicle 102 to swap batteries in the battery swapping station 100. The swapping station 100 further comprises a swapping station outlet 101. After the swapping of the vehicle 102 is finished, the vehicle 102 in the swapping area 106 can leave the swapping station 100 from the swapping station exit 101. As shown in fig. 1, since the power interchange station exit 101 is located on the front side of the power interchange station 100, the vehicle 102 after the end of power interchange can be driven from the front side of the power interchange station 100 to the area outside the power interchange station 100.

The monitoring area 103 and the safety area 104 are both located in the outer area of the power conversion station 100, and the monitoring area 103 is close to the safety area 104. No matter in the automatic driving mode or in the manual driving mode, due to the limitation of the form of the battery replacement station, the battery replacement vehicle does not have a complete and effective understanding of the traffic environment outside the station from the visual range of the sensor of the vehicle and the driver. That is, when the vehicle 102 is located in the battery swapping area 106 within the battery swapping station 100, it cannot sense or observe the traffic condition in the area outside the battery swapping station 100. This presents a certain safety risk for the vehicle that is about to exit the power exchange station 100. As illustrated in fig. 1, the safe area 104 is adjacent to the power station outlet 101, and thus traffic conditions of the safe area 104 are particularly important for the vehicle 102 to safely drive away from the power station 100.

The present application analyzes and predicts the risk condition of the safety area 104 by monitoring the traffic condition of the monitoring area 103 so as to guide the vehicle 102 to move away from the charging station 100. In the embodiment, the area related to the monitoring area 103 covers the area related to the safety area 104, and the larger area 103 of the monitoring area is beneficial to collecting more data about the traffic condition of the area outside the power exchanging station 100, so that the risk condition of the safety area 104 can be more accurately analyzed and predicted. In other embodiments, the monitoring area 103 and the safety area 104 may be arranged in other ways according to requirements. In addition, one or more deceleration strip devices are arranged on a safety area 104 outside the power swapping station 100. The arrangement of the deceleration strip device can effectively reduce the running speed of vehicles moving to and from the safe area 104, improve the safety and reliability of the vehicle after power change when the vehicle leaves the station, enhance the identification degree of the safe area 104 outside the power change station 100, and improve the thought awareness of the vehicle and drivers and passengers on entering the safe area 104. For example, some embodiments provide two deceleration strip assemblies on the safety area 104, one at each end of the safety area 104 in the direction of travel, using a minimum number of deceleration strip assemblies to achieve the goal of decelerating the vehicle from whichever direction the external vehicle enters the safety area 104. The arrangement of the deceleration strip device can be selected according to actual requirements. In other embodiments, no deceleration strip device or other types of deceleration devices may be disposed on the safety region 104 outside the swapping station 100.

A display 107 is further provided in the power swapping station 100, as shown in fig. 1, the display 107 is located at a position of the swapping station area 106 close to the swapping station outlet 101, so as to prompt an occupant on the vehicle 102 about to exit with information about a risk condition of the safety area 104 outside the station.

Fig. 2 shows a schematic view of an apparatus 200 for guiding a vehicle 102 away from the charging station 100 shown in fig. 1. As shown in fig. 2, the apparatus 200 for guiding the vehicle 102 away from the charging station 100 includes a risk monitoring unit 201, a target analysis unit 202, a driving mode determination unit 203, an output unit 204, and a vehicle monitoring unit 205. Among them, the risk monitoring unit 201 is communicatively connected to the target analyzing unit 202, the target analyzing unit 202 is communicatively connected to the output unit 204, the vehicle monitoring unit 205 is communicatively connected to the risk monitoring unit 201, and the driving mode determining unit 203 is communicatively connected to the output unit 204.

The risk monitoring unit 201 is configured to monitor the monitored area 103 to discover and monitor risk targets 105 (see fig. 1) in the monitored area 103. As can be seen in fig. 1, the risk target 105 is a vehicle that is about to drive into the monitored area 103. In other embodiments, risk targets 105 may also be other things, such as pedestrians, obstacles, and the like. When the risk monitoring unit 201 finds a risk object 105 entering the monitoring area 103, the risk monitoring unit 201 continuously monitors the motion trajectory of the risk object 105 and generates data describing the motion trajectory of the risk object 105.

The target analysis unit 202 is configured to: in a condition where the risk monitoring unit 201 finds the risk target 105, receives monitoring data describing a movement trajectory of the risk target 105 from the risk monitoring unit 201, and predicts the behavior of the risk target 105 by analyzing these monitoring data, the target analysis unit 202 is also able to determine the risk condition of the safety area 104 from the predicted behavior of the risk target 105. In the present embodiment, the target analysis unit 202 can generalize and deduce the motion law of the risk target 105 by analyzing the monitoring data describing the motion trajectory of the risk target 105. The predicted behavior of risk target 105 includes predicting a location where risk target 105 will appear when monitored to a later time t, where time t is selected from 0.5 seconds to 5 seconds. In the present embodiment, time t is 1 second, i.e. target analysis unit 202 is configured to predict the location where risk target 105 will appear when monitored 1 second later. In some embodiments, the secure area 104 is divided into n sub-secure areas (not shown), where n is a natural number selected from 2 to 5. The n sub-security regions correspond to different security levels, respectively. In this embodiment, the different security levels corresponding to 3,3 sub-security zones are represented by green, orange and red, respectively. Under the condition that the target analysis unit 202 can predict the position where the risk target 105 will appear at the time t after being monitored, if it is predicted that the risk target 105 will appear in one of the sub-safety regions of the safety region 104 at the time t after being monitored, the risk condition of the safety region 104 includes the safety level of the sub-safety region where the risk target 105 is predicted to arrive. For example, if it is predicted that risk target 105 will appear in a sub-safety zone of the green level after 1s, the risk status of safety zone 104 is the green level.

The driving mode determination unit 203 is configured to: the driving mode of the vehicle 102 is detected so that the output unit 204 can determine its output manner according to the determination result of the driving mode. In this embodiment, the apparatus 200 for guiding the vehicle to leave the power switching station 100 includes the driving mode determination unit 203, so that the output unit 204 can receive the determination signal from the driving mode determination unit 203 to adopt different output modes for different driving modes, and in other embodiments, the apparatus 200 for guiding the vehicle to leave the power switching station 100 may not include the driving mode determination unit 203 and does not switch the output modes for different driving modes.

The output unit 204 is configured to receive the risk condition of the safety area 104 from the target analysis unit 202 and notify the vehicle 102 or an occupant of the vehicle 102 of the risk condition. The output unit 204 may be configured to output different modes for different driving modes of the vehicle. In the present embodiment, for the automatic driving mode, the output unit 204 does not notify the vehicle 102 on the condition that the safety area 104 is at risk, and notifies the vehicle 102 that the outbound is possible only on the condition that the safety area 104 is not at risk. In the present embodiment, a situation where the risk monitoring unit 201 does not monitor the risk object 105 in the monitoring area 103 is considered as that the safety area 104 has no risk, and if the risk monitoring unit 201 monitors the risk object 105 in the monitoring area 103, the situation is considered as that there is risk. In other embodiments, the risk of the security area 104 may be determined according to other risk determination criteria. For the manual driving mode, the output unit 204 outputs the risk status of the safety region 104 on the display 107 within the charging station 100. For example, corresponding to the risk condition of the safety area 104 being a green level, the charging station 100 displays a green light on its display 107 to alert the driver and passengers: there is a security risk on the child security region of the security region 104 represented by the green level.

The vehicle monitoring unit 205 is configured to monitor the vehicle 102 to determine whether the vehicle 102 completely leaves the charging station 100, if so, notify the risk monitoring unit 205 to stop monitoring the monitoring area 103, and if not, allow the risk monitoring unit 205 to continue monitoring the monitoring area 103. In the present embodiment, the vehicle monitoring unit 205 determines whether the vehicle 102 completely leaves the power swapping station 100 by monitoring whether the vehicle 102 exists in the power swapping area 106 in the power swapping station 100 and monitoring whether the vehicle 102 exists in the safety area 104 outside the power swapping station 100. For example, if the vehicle monitoring unit 205 monitors that the vehicle 102 exists in any one of the battery swapping area 106 and the safety area 104, it is determined that the vehicle 102 does not completely leave the battery swapping station 100; if the vehicle monitoring unit 205 monitors that the vehicle 102 does not exist in the battery swapping area 106 and the safety area 104, it is determined that the vehicle 102 completely leaves the battery swapping station 100.

Next, a method 300 of guiding the vehicle 102 away from the charging station 100 according to an embodiment of the present application will be explained with reference to fig. 3.

Fig. 3 shows a schematic diagram of a method 300 of guiding a vehicle away from the swapping station 100 shown in fig. 1. The device 200 for guiding the vehicle 102 to leave the power swapping station in fig. 2 comprises a risk monitoring unit 201, a target analysis unit 202, a driving mode judgment unit 203, an output unit 204 and a vehicle monitoring unit 205, and the method 300 for guiding the vehicle to leave the power swapping station 100 in fig. 3 comprises a risk monitoring step 301, a target analysis step 302, a driving mode judgment step 303, an output step 304 and a vehicle monitoring step 305. Wherein the risk monitoring step 301 is performed by the risk monitoring unit 201, and is capable of performing the steps that can be performed as described for the risk monitoring unit 201 in fig. 2; the target analysis step 302 is performed by the target analysis unit 202, and is capable of performing the executable steps described for the target analysis unit 202 in fig. 2; the driving mode determining step 303 is performed by the driving mode determining unit 203, and can perform the steps described for the driving mode determining unit 203 in fig. 2; the outputting step 304 is performed by the outputting unit 204, and is capable of performing the steps that can be performed as described for the outputting unit 204 in fig. 2; the vehicle monitoring step 305 is performed by the vehicle monitoring unit 205 and can perform the steps that can be performed as described for the vehicle monitoring unit 205 in fig. 2. As shown in fig. 3, the risk monitoring step 301, the target analyzing step 302, the driving mode judging step 303, the outputting step 304 and the vehicle monitoring step 305 are sequentially executed in order, and in an actual operation process, these several steps may be executed in other orders, or several of them may be executed in parallel.

The specific flow of the method 300 for guiding the vehicle 102 away from the swapping station 100 in fig. 3 is described in detail by taking fig. 4 as an example.

Fig. 4 shows a flow chart of the method 300 shown in fig. 3. As shown in fig. 4, the method 300 of guiding the vehicle 102 away from the swapping station 100 is performed according to the following flow: the start step 401 is entered first. In this embodiment, the method proceeds to the starting step 401 after the vehicle 102 completes the battery swapping in the battery swapping area 106 of the battery swapping station 100. In other embodiments, the vehicle 102 located within the swapping area 106 may proceed to the start step 401 under other conditions that require an outbound trip. Subsequently, step 402 is performed by the risk monitoring unit 201 to monitor the risk target 105 of the monitored area 103. If the risk monitoring unit 201 finds a risk target 105 in the monitored area 103, step 403 is performed by the target analysis unit 202 to further confirm the location of the risk target 105. In the process of executing step 403, the risk monitoring unit 201 continues to monitor the behavior of the risk target 105, for example, the motion trajectory of the risk target 105, for the target analysis unit 202 to further analyze the motion pattern of the risk target 105. In step 403, the target analysis unit 202 can further predict the position where the risk target 105 will appear when monitored for a later time t (e.g., after 1 second) by analyzing the motion data of the risk target 105.

Step 404 is performed after step 403 to determine if the vehicle 102 is an autonomous vehicle. If it is an autonomous vehicle, step 408 is performed to further determine whether the safety zone 104 is currently in a safe state. The safe state indicates that the safety area 104 does not have a risk currently, and in this embodiment, the condition that the risk object 105 is not monitored in the monitoring area 103 is regarded as that the safety area 104 is in the safe state. If it is determined in step 408 that the safety area 104 is not currently in a safe state, the process returns to step 402 to continuously monitor the monitored area 103 for the presence of the risk target 105, so as to continuously provide driving advice for the vehicle 102. If it is determined in step 408 that the safe area 104 is currently in a safe state, step 409 is performed to notify the vehicle 102 to automatically drive away from the power exchange station 100. The above arrangement enables the autonomous vehicle to travel out of the charging station 100 again while ensuring all that is sufficiently safe. Step 407 is further performed after step 409.

If step 404 determines that the vehicle 102 is not an autonomous vehicle, then steps 405 and 406 are performed in sequence. In step 405, the security area 104 is divided into 3 sub-security areas corresponding to different security levels, the 3 sub-security areas being represented by green, orange and red, respectively. If the risk target 105 is predicted to appear in the green level safety sub-area after the monitored 1 second, step 406 is performed to display a green light at the station end of the power swapping station 100 to provide a risk alert to the occupants of the vehicle 102. Providing the occupant of the vehicle 102 with information of the risk status of the safety zone 104 will effectively help the occupant decide whether to drive out. In the present embodiment, step 405 is implemented by the target analysis module 202, and step 406 is implemented by the output unit 204. Step 407 is further performed after step 406.

In step 407, whether the vehicle 102 exists in the power swapping area 106 and the safety area 104 is monitored by the vehicle monitoring unit 205 to determine whether the vehicle 102 completely exits the station of the power swapping station 100. If the vehicle 102 exists in any one of the power swapping area 106 and the safety area 104, that is, the vehicle 102 does not completely exit the power swapping station 100 station, the process returns to step 402 to continuously monitor whether the risk target 105 exists in the monitoring area 103, so as to continuously provide driving advice for the vehicle 102 that does not completely exit the power swapping station 100 station. If the vehicle 102 does not exist in the swapping area 106 and the safety area 104, that is, the vehicle 102 completely exits the station of the swapping station 100, the ending step 410 is entered.

By the method 300 of guiding the vehicle 102 away from the power swapping station 100 as described above, the vehicle 102 can be quickly and safely driven out of the power swapping station 100 after the power swapping is completed. The method 300 of the present application for guiding the vehicle 102 away from the charging station 100 may be applied to an electric-only vehicle, a hybrid vehicle, and the like.

Further aspects of the present application also provide a computer storage medium comprising instructions that when executed may perform the method 300 of guiding the vehicle 102 away from the swap station 100 described above with reference to fig. 1-4.

For the scenario of the battery swapping station 100, the device 200 and the method 300 for guiding the vehicle 102 to leave the battery swapping station 100 according to the present application can be independently used as a station-side intelligent and automatic function, and can also become a loop in a full-self-service battery swapping service process. The device 200 and the method 300 for guiding the vehicle 102 to leave the power swapping station 100 are applicable to the scene of a full-self-service power swapping station, and the vehicle 102 can leave the station after power swapping under the condition that no station-side watch staff exists. The device 200 and the method 300 for guiding the vehicle 102 to leave the battery swapping station 100 can protect the safety of the battery swapping vehicle and drivers and passengers, maintain the sequence of the unattended battery swapping station 100 and ensure the operation efficiency of the battery swapping station 100.

The device 200 and the method 300 for guiding the vehicle 102 to leave the battery replacing station 100 can be applied to a scene in which the peripheral computing equipment is linked with the station, the vehicle and the cloud to form an effective service network, and can create a whole set of full-self-service battery replacing station flow which mainly uses automatic detection, is assisted by communication between the battery replacing station and the vehicle and is fed back to the bottom by the cloud in the peripheral computing equipment by taking AI artificial intelligence image reasoning as an entrance.
