[0001] The present application relates to the field of vehicle intelligent control technology, and more specifically, to an automobile intelligent accompanying method. Background Art

[0002] In traditional life, people encounter a common problem when traveling by car: what to do when you don’t need a car for a period of time, but need to drive it later? There are many such scenarios, such as wanting to take a walk after attending a party before driving home; walking in a park or in the mountains with family and friends, and then driving away, etc. The usual practice is to wait until the event is over and then drive away from the original place, which brings considerable inconvenience to people. Summary of the invention

[0011] Preferably, in the destination accompanying mode, if the preset arrival time of the car is greater than or equal to the difference between the user's first estimated arrival time and the car's advance arrival time, the car is automatically controlled to depart immediately;

[0012] If the preset arrival time of the car is less than the difference between the user's first estimated arrival time and the car's advance arrival time, the car is automatically controlled to wait at the location. When it reaches half of the first estimated arrival time, the car is automatically controlled to set off immediately.

[0013] Preferably, if the sum of the waiting time at the place and the preset arrival time is greater than the difference between the first estimated arrival time and the early arrival time of the car, the car is automatically controlled to depart immediately.

[0027] Other features and advantages of the present application will become apparent from the following detailed description of exemplary embodiments of the present application with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the application and, together with the description, serve to explain the principles of the application.

[0030] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0031] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0034] The present application provides a method for intelligent car accompaniment. When a user does not need to drive temporarily but needs to drive later, the car can automatically move to the parking position closest to the user, so that the user can get on the car as soon as possible when needed, and minimize the trouble of the user finding the car. In addition, in the present application, the car can also use the intelligent rescue mode to ask for help from the outside world or realize self-help rescue through its own control when the user encounters danger after leaving the car, which greatly improves the convenience and success rate of rescue.

[0035] The automobile intelligent accompanying method provided in the present application is applicable to the intelligent driving system of the automobile. Through the interaction between the user's mobile terminal and the intelligent driving system, the automobile can move with the user after the user leaves the car.

[0036] like Figure 1 As shown, the automobile intelligent accompanying method provided by this application includes:

[0037] S110: Receive intelligent accompanying instructions.

[0038] As an embodiment, the intelligent accompanying instruction includes an intelligent accompanying mode.

[0039] S120: Tracking the location information of the user's mobile terminal (as the user's location information).

[0040] S130: According to the intelligent accompanying mode indicated by the intelligent accompanying instruction, the car is automatically controlled according to the location information of the mobile terminal to move the car to the parking position closest to the user.

[0041] As an embodiment, the intelligent accompanying mode includes a real-time accompanying mode, a destination accompanying mode, and a periodic updating accompanying mode. In the real-time accompanying mode, the intelligent driving system follows the location information of the mobile terminal in real time and moves in real time according to the location. In the destination accompanying mode, after the user inputs the destination location to the intelligent driving system, the car can automatically turn on the accompanying mode and move to the destination before the user arrives at the destination. The periodic updating accompanying mode includes a time periodic updating mode and a distance periodic updating mode. In the time periodic updating mode, the intelligent driving system updates the location information of the mobile terminal at every preset time, and automatically moves to the parking position closest to the mobile terminal to wait. In the distance periodic updating mode, through the real-time positioning of the mobile terminal, each time the user moves a preset distance, as a cycle, the intelligent driving system automatically drives the car to follow and stops at the nearest parking position to wait.

[0042] The real-time accompanying mode is mainly used in suburbs and parks where there are few people and vehicles, or in time periods or sections where there are few people and vehicles. Depending on the application scenarios, there are two situations where the pedestrian route and the vehicle route are consistent or inconsistent, and the pedestrian and vehicle route are respectively adopted. For example, after the user leaves the car and walks on the side of the road, the vehicle can accompany directly behind him, that is, the pedestrian and vehicle route is adopted. If the user needs to pass through non-vehicle routes such as parks and scenic spots after leaving the car, the vehicle can only accompany on a similar vehicle route, that is, the pedestrian and vehicle route is adopted.

[0043] Preferably, when the vehicle-passenger route is used, the intelligent driving system tracks the location information of the user's mobile terminal in real time, determines the most likely destination (e.g., the most likely park or scenic spot exit), and automatically selects the optimal driving route to control the car to move to the destination. It is understandable that the user can also manually select the optimal driving route on the mobile terminal, and the intelligent driving system moves the car to the destination according to the manually selected driving route. This embodiment is suitable for the case where the user cannot leave the park or scenic spot to find the car before reaching the above-mentioned destination.

[0044] Preferably, when the pedestrian and vehicle separation method is adopted, if there are multiple parking nodes on the pedestrian route that are closest to the vehicle route, the car is automatically controlled to reach the parking node closest to the destination before the user reaches the destination. This embodiment is suitable for the situation where the user cannot come out of the park or scenic area to find the car before reaching the above-mentioned destination. For example, the parking node closest to point A on the vehicle route is point A', and the parking node closest to point B on the vehicle route is point B', where point A is upstream of point B, and point B' is the parking node closest to the destination on the vehicle route. When the user walks to point A, the car arrives at point A', and in the process of the user walking from point A to point B, the intelligent driving system automatically controls the car to move from point A' to point B' at one time, and then waits for the user at point B'.

[0045] Preferably, if the vehicle route or pedestrian route is tortuous, so that the car needs to turn back when the user walks from point C to point D, the intelligent driving system controls the car to remain stationary until the car needs to move forward again. When the pedestrian route changes, the vehicle route is updated, and the intelligent driving system controls the car to turn around.

[0046] Preferably, when the pedestrian-vehicle separation method is adopted, after the ambient light is lower than the light threshold, the intelligent driving system automatically controls the lighting on the side close to the user.

[0047] Preferably, when the vehicle and the person are on the same road, after the ambient light is lower than the light threshold, the intelligent driving system automatically controls the vehicle's lights to light up, so that the user is within the illumination range of the lights, and the distance between the vehicle and the user is within a preset range.

[0048] The destination accompanying mode can be applied to areas with a large number of people and vehicles. The main application scenarios are: users temporarily use other means to go to the destination; in medium and large cities, when encountering traffic jams, roadblocks, etc., users go to the destination by themselves in order to save time. At this time, the destination accompanying mode is needed to let the vehicle go to the destination together.

[0049] In the destination accompanying mode, if there is no traffic jam, roadblock, etc., and the preset arrival time t2 of the car is greater than or equal to the difference between the user's first estimated arrival time t1 and the car's advance arrival time t0 (for example, 5 minutes) (that is, t2≥t1-t0), the car will be automatically controlled to depart immediately.

[0050] If the preset arrival time t2 of the car is less than the difference between the user's first estimated arrival time t1 and the car's advance arrival time t0 (i.e. t2<t1-t0), the car will be automatically controlled to wait in place. When it reaches half of the first estimated arrival time t1, the car will be automatically controlled to start immediately, thereby preventing the user from suddenly canceling the original plan during the journey or wanting to return to the car for some reason. In this case, if the vehicle has arrived at the destination before the user has completed half of the pedestrian route, the user will need to spend more than half of the first estimated arrival time to get on the car. If the vehicle is still in place at this time, the user will need to spend less than half of the first estimated arrival time to return along the original route.

[0051] Preferably, if the sum of the on-site standby time t3 and the preset arrival time t2 is greater than the difference between the first estimated arrival time t1 and the car's early arrival time t0 (ie t3+t2≥t1-t0), the car is automatically controlled to depart immediately to prevent the user from waiting for the car at the destination.

[0052] Preferably, in the destination accompanying mode (especially when encountering traffic jams, roadblocks, etc.), first determine whether the remaining energy of the vehicle is sufficient to reach the destination. If insufficient, the intelligent driving system will issue an energy alarm to the mobile terminal and will not start the car accompanying.

[0053] The scope and scenarios of application of the periodic update companion mode are also relatively wide.

[0054] As an embodiment, in the periodic update accompanying mode, the following steps are repeated until the user gets on the bus:

[0055] P1: Predict the user's movement trajectory in the next collection cycle (time collection cycle or distance collection cycle) based on the current pedestrian route.

[0056] P2: Determine the initial vehicle route based on the moving trajectory.

[0057] P3: Collect the user's actual location information in the next collection cycle.

[0058] P4: Determine the parking location closest to the user on the initial driving route based on the actual location information.

[0059] P5: Automatically control the car to move from its current position to the parking position closest to the user.

[0060] As an embodiment, the collection cycle of the present application is a time period or a distance range, for example, a time collection cycle is 10-15 minutes, that is, the location information of the mobile terminal within 5 minutes is collected each time. In this case, the parking position corresponding to the last location information collected in the collection cycle shall prevail.

[0061] Preferably, the above-mentioned intelligent companion mode has a preset remote control range (for example, within 150 meters) to avoid misoperation when one person is in multiple cars, and difficulty in calculating the route when the car is looking for a person.

[0062] On the basis of the above, preferably, the intelligent accompanying instruction also includes turning on the intelligent rescue mode. After the intelligent rescue mode is turned on, the intelligent driving system turns on the rescue mode when it detects that the user is in danger through the user's mobile terminal signal.

[0063] As an embodiment, the intelligent rescue mode includes a passive rescue mode and an active rescue mode.

[0064] In passive rescue mode, the intelligent driving system performs the following steps:

[0065] Q1: If it is determined that the user is in danger, a danger alert is issued to the user.

[0066] As an embodiment, when determining that a user is in danger, the intelligent driving system first reads the user's location information, motion information, and the user's surrounding environment, and then determines whether the user is in danger based on this information.

[0067] For example, the intelligent driving system obtains the user's altitude and acceleration, determines the rivers around the user in the map, and makes the following determinations:

[0068] A: If the altitude changes by more than 50-75m / min, the user is considered to have fallen.

[0069] B: If the user is in a river on the map and remains still for more than 3-5 minutes, or moves more than 100-150 meters in the river, the user is considered drowning.

[0070] C: The user's own acceleration peak reaches 1.5-2g (g is the acceleration due to gravity) or above, and the user is judged to have collided.

[0071] When at least one of the above judgments is true, it is determined that the user is in danger, and the intelligent driving system sends a danger alert to the user.

[0072] Q2: If the user does not respond to the danger alarm within the preset time or does not respond to at least two danger alarms, the first external rescue function is activated. If the user actively responds to the danger alarm, it means that the user is not in danger, and the smart rescue process ends.

[0073] Among them, the first external rescue function includes:

[0074] ① Send a distress message to the user's emergency contacts, including: the user's name, phone number, surrounding map and user location, alarm time, time the user left the car, and a half-length photo when leaving the car (automatically taken by the intelligent driving system when the car is parked and the engine is turned off), thereby providing necessary information for search and rescue.

[0075] ② The car sends out a distress voice and lights, and the trunk opens at the same time, popping out a rescue tool package. The items in the package include: an automatically opened tablet that displays: emergency contact information; the user's name, phone number, surrounding map and user location, alarm time, user departure time, and a half-body electronic photo of the user when leaving the car; a portable swimming ring, a 30-meter safety rope, a strong flashlight, a small marching pickaxe, a thank-you fee and a disclaimer. The disclaimer guarantees that the car owner will not pursue any responsibility for any actions taken by anyone after taking this package.

[0076] When a user encounters a problem while traveling, the active help mode can be turned on. In this application, active help includes emergency active help and control active help.

[0077] Emergency active help is applicable to situations such as encountering wild animals or criminals in the wild. When the intelligent driving system detects emergency active help signals such as one-handed, silent, and uncommon continuous operations on the user's mobile terminal (for example, continuous flipping of the terminal, pressing a button more than 20 times in a row, or more than 5 consecutive bumps), the intelligent driving system automatically turns on the emergency active help mode: the intelligent driving system reads the phone number and WeChat of the emergency contact, remotely controls the user's mobile terminal to start recording, stores the recording in the intelligent driving system, and then turns on the second external rescue function.

[0078] Preferably, in addition to the above-mentioned first external rescue function, the second external rescue function also includes sending real-time information transmitted from the user's mobile terminal to the emergency contact, including: video clips (for example, 30 seconds of video is transmitted each time at an interval of 5 minutes).

[0079] Active control for help is suitable for situations where you are trapped in the wild, such as falling or breaking a leg, where it may be difficult to get outside help. Users can send active control for help signals to the intelligent driving system through their mobile terminals. After the intelligent system turns on the active control for help mode, it can control the car to approach the user by receiving control signals from the user's mobile terminal, thus realizing the external driving function.

[0080] Specifically, the user first drives the car to the nearest road section through the above-mentioned car accompanying method through the mobile terminal. When there is no regular path between the car and the user's location, it can be switched to the external driving function:

[0081] The operation screen is simulated in the mobile terminal (such as APP), and multiple screens are matched (such as the car surrounding screen in the top view, the front screen of the vehicle in the front view, the map and the vehicle direction screen) through the car laser radar or camera image framing. Multiple screens can coexist and can be switched at any time. The user selects one of the multiple gears as the current driving speed through the mobile terminal. Then the car is controlled to move left and right and emergency brake through the operation interface of the mobile terminal. Through the external driving function, the car can be driven to the side without external help, or driven to the nearest position due to road problems, and the user can get on the car when he can move.

[0082] When the vehicle cannot move to the user, or the vehicle moves far away from the user, and the user has difficulty in moving, the user can send a drone delivery command to the intelligent driving system through the mobile terminal, and the intelligent driving system will start the drone delivery function:

[0083] The intelligent driving system controls the opening of the car trunk and the start-up of the drone, so that the drone connects to the intelligent driving system to read the map, generates a flight path from the car to the user, and after receiving the user's confirmation signal for the flight path and the drone's flight speed instruction, the drone flies to the user with the rescue package and delivers the rescue package to the user. After successful delivery, it lands next to the user and waits for new instructions.

[0084] Among them, the rescue package includes not only the above-mentioned rescue tool package, but also a survival package, including a certain amount of drinking water, compressed biscuits, mountaineering knives, climbing ropes, etc., so as to ensure that the occupants can escape or maintain their lives.

[0085] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
