Detailed Description
In order to make the technical problems, technical solutions and advantageous technical effects to be solved by the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and a plurality of exemplary embodiments. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Fig. 1 is a flowchart schematically illustrating main steps of a vehicle light illumination method according to an exemplary embodiment of the present invention. As shown in fig. 1, a vehicle light illumination method according to an exemplary embodiment of the present invention mainly includes the steps of:
s1: acquiring travel destination information of a vehicle user;
s2: determining a path of a user to a destination according to the travel destination information and parking information of a vehicle, wherein the parking information comprises parking azimuth information and parking environment information; and
s3: a lighting operation of an associated lighting device of the vehicle with respect to the path is determined based on the determined path and the parking environment information.
In step S1, for example, the life schedule information of the user may be obtained from the mobile terminal of the user by communicating with the mobile terminal of the user such as a smart phone or a tablet computer, and then the travel destination information of the current trip may be extracted from the life schedule information in combination with the time. For example, the user makes an appointment for seven night to go to a hotel, the appointment information is recorded in a schedule type application of the smart phone, and then the corresponding hotel can be acquired from the schedule type application by communicating with the smart phone and takes the address of the hotel as trip destination information. If the current time is six and a half in the evening and no other journey is performed before seven, the hotel address can be determined to be the travel destination information of the current trip. Alternatively, in the case where the user inputs the destination in the navigation system, travel destination information may be directly acquired from the navigation system. In an alternative embodiment, the travel history of the user may also be recorded and counted, and the possible travel destination is estimated according to the travel history information and the travel route. The user here may be any driver using the vehicle. The user can register in the car system, record the user information in the car system in advance, log in the car system through authentication operations such as face brushing and finger print brushing after each time the user gets on the car, so as to synchronize schedule information or record and extract historical data, and can also manually connect the mobile terminal with the car system in a communication way so as to perform operations such as information synchronization.
In step S2, parking information of the vehicle is determined when the vehicle is in a parked state and at least one door is transitioned from a locked state to an openable unlocked state. Alternatively, when the vehicle is in a flameout state and the distance from the travel destination is smaller than a predetermined value, the parking information of the vehicle is determined. That is, when the vehicle waits for a traffic signal, for example, in the middle of a driving route, or when it is parked temporarily due to other circumstances, the vehicle is not considered to arrive at the destination, and the parking information of the vehicle is not determined. Only when the door is changed to an openable unlocked state, or the vehicle is flameout and the vehicle is closer to the travel destination, it is considered that there is a user about to get off and the parking information of the vehicle is determined. The predetermined value may be a value set by the user himself or a value determined according to the environmental road conditions, for example, the predetermined value may be increased appropriately when only walking is allowed within a predetermined range around the destination.
As described above, the parking information of the vehicle includes the parking azimuth information and the parking environment information. The vehicle orientation information includes a parking position of the vehicle and a vehicle orientation. The vehicle position information can be determined by means of a vehicle navigation system, a positioning system, a high-precision map and the like, so that the relative position relationship between the vehicle and the destination can be determined. The parking environment information includes static object information and environment brightness information. The surrounding environment of the vehicle can be detected by various environment sensors such as cameras and radars mounted on the vehicle to identify static objects such as grass, trees, road facilities and other obstacles in the surrounding environment as static object information. Ambient brightness information can be detected by means of an ambient brightness sensor. After determining the various parking information described above, the destination information may be combined to determine a specific path for the user to walk from the vehicle to the destination.
In a preferred embodiment, after determining the parking information, the opening of the door is also awaited to enable further determination of the path the user walks in conjunction with the opened door. The opening of the door can be detected by means of a door lock sensor or the like. More preferably, the dynamics of the user and the opening of the door can also be detected by means of the in-car and/or out-car camera, so that it is also possible to identify which user gets off at the same time in order to be better associated with the destination information of the respective user.
In step S3, after the path is determined, the relevant lighting device to be activated and its lighting operation with respect to the path may be determined based on the determined path and parking environment information. Wherein it may first be determined whether illumination is required based on ambient brightness information. For example, when the daytime environment is high in brightness, a symbol indicating the direction may be displayed or projected only at a specific position with a certain brightness without lighting, or the user may be prompted with voice. When the ambient brightness is low, the brightness, color, and/or display content of the illumination, etc. may be determined according to the ambient brightness. The illumination range and/or dynamic pattern of the illumination to be illuminated may be determined based on the determined path and the static object information and the vehicle lighting device to be activated may be determined accordingly. Wherein the illumination range and/or dynamic pattern is to be determined such that the user can see and avoid various obstacles that may be present and can appreciate the location of the destination. The relevant lighting device may be selected from all external lighting devices with which the vehicle is equipped, such as a headlight, a taillight, a license plate light, an LED lamp integrated on a door or a body frame or an LED lamp integrated in an exterior mirror, etc.
In a particularly preferred embodiment, the user's location is further tracked and identified after getting off the vehicle, and the determined path is updated in conjunction with the user's real-time location. Thus, for example, when a user needs to bypass the car body to take articles from another car door or trunk, the following path illumination can be provided for the user, and the safety of the user is further ensured.
An example of a scene to which the vehicle light illumination method according to an exemplary embodiment of the present invention is applied is described below with reference to fig. 2.
In the example shown in fig. 2, it is assumed that the vehicle H is parked near the travel destination TD and the right rear door is opened in a dark ambient brightness, and the determined path is shown by a thick arrow in the figure. In addition, it is detected from the environmental sensor that there is a bush O1 beside the path, and there is an obstacle O2 in the path, which is, for example, a puddle, a construction point, or some kind of obstacle temporarily placed. According to the above information, it is possible to determine that the body lamp having the illumination range R1 and the exterior mirror lamp having the illumination range R2 are turned on, and the illumination ranges of both can cover the determined path and the related obstacle, so that the user can be effectively assisted to avoid the obstacles O1 and O2. Furthermore, dynamic or static arrows may be projected on the ground within the illumination range to alert the user to the direction of travel. The headlights with illumination range R3 may also be turned on to provide direction indication or path illumination, for example by flashing the headlights at a predetermined frequency to prompt the user to move in the direction of the head of the vehicle after getting off the vehicle, as desired. It is contemplated that the illumination colors of the three regions R1, R2, R3 may be graded to provide directional indications, or that one or both regions may be dynamic. It is also contemplated that a left-side related lighting device may be turned on to provide illumination and path guidance to the user when the user is detected as exiting the left door.
By using the vehicle light illumination method provided by the embodiment of the invention, proper path guidance and safety illumination can be provided for the user leaving the vehicle, and the use experience of the user is improved.
As shown in fig. 3, the present invention also provides a corresponding vehicle light illumination system 100, which includes at least a controller 10. The controller 10 is implemented, for example, as an Electronic Control Unit (ECU) of the vehicle. The controller may comprise a memory storing computer program instructions and a processor, which, when executed by the processor, is capable of, for example, performing or at least assisting in the performance of the above-described vehicle lighting method according to an embodiment of the invention. The computer program product may be stored in a computer readable storage medium. The computer readable storage medium may include, for example, high speed random access memory, but may also include non-volatile memory, such as a hard disk, memory, a plug-in hard disk, a smart memory card, a secure digital card, a flash memory card, at least one magnetic disk storage device, a flash memory device, or other volatile solid state storage device. The processor may be a central processing unit, but also other general purpose processors, digital signal processors, application specific integrated circuits, off-the-shelf programmable gate arrays or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general purpose processor may be a microprocessor or may be any conventional processor or the like. The controller 10 may be a dedicated controller for the vehicle light illumination method according to the embodiment of the present invention, or may be integrated in a central controller of the vehicle, or the controller 10 may be implemented as the central controller.
