Description

Technical Field

[0001] The present invention belongs to the field of automobile technology, and in particular relates to a lighting control system and method for an automobile charging port. Background Art

[0002] With the rapid development of new energy vehicles, electric vehicles are loved and used by more and more users. When users charge their cars, in order to facilitate users to plug and unplug the charging gun and accurately insert the charger into the charging port of the charging socket at one time, electric vehicles will provide a lighting system for the charging port.

[0003] Most of the existing electric vehicles are equipped with charging port lights, which are turned on through mechanical structures or cover opening as a prerequisite. However, the existing charging port lights do not pay attention to the specific intensity of external light. When the external light is strong, users can accurately plug and unplug the charging gun without turning on the charging port lights, and there is no need to turn on the charging port lights every time. Summary of the invention

[0004] In view of the above problems, the present invention provides a vehicle charging port lighting control system and method.

[0005] The present invention is achieved through the following technical solutions:

[0006] In a first aspect, a vehicle charging port lighting control system includes:

[0007] light and rain sensor, body control module, charging port cover actuator, charging port lighting, and battery management system module;

[0008] The optical rain sensor is connected to the vehicle body control module via an on-vehicle wired network;

[0009] The battery management system module and the body control module are connected via an on-vehicle wired network;

[0010] The lamp charging port cover actuator is connected to the body control module via a common vehicle wiring harness;

[0011] The charging port lighting is connected to the body control module through a common vehicle wiring harness.

[0012] In some embodiments, the in-vehicle wired network includes a CAN bus and a LIN line.

[0013] In some embodiments, the battery management system module and the body control module perform signal interaction via a CAN bus;

[0014] The optical rain sensor and the vehicle body control module perform signal exchange via a LIN line.

[0015] In some embodiments, the body control module collects the charging port cover opening status through a feedback hard line of the charging port cover actuator.

[0016] In some embodiments, the charging port lighting is directly driven and lit by the body control module.

[0017] In a second aspect, a method for controlling lighting of a vehicle charging port includes:

[0018] When the vehicle is stationary, the light intensity of the external light is greater than or equal to the threshold value, as sensed by the light and rain sensor;

[0019] The opening and closing status of the charging port cover is obtained through the body control module;

[0020] When the charging port cover is in the open state, the charging port lighting lamp is driven to light up by the body control module;

[0021] When the charging port cover is in a closed state, the charging port lighting lamp is stopped from being driven by the body control module;

[0022] When the body control module obtains the jump status of the charging gun being inserted or unplugged through the battery management system module, the charging port lighting is driven to light up through the body control module.

[0023] In some embodiments, the threshold is a set light intensity required to illuminate the charging port lighting.

[0024] In some embodiments, the opening and closing status of the charging port cover is fed back to the body control module by the charging port cover actuator.

[0025] In some embodiments, the charging port lighting light automatically turns off after being lit for a period of time.

[0026] In some embodiments, when the light intensity of the external light sensed by the light rain sensor is greater than the threshold, the charging port lighting will not light up.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. Use existing components on the vehicle to refine the lighting scenes of the charging port lights, saving costs;

[0029] 2. The usage scenarios of light intensity are refined;

[0030] 3. It is divided into scenes with sufficient light and scenes with insufficient light, and provides targeted lighting services for the charging port, thus improving the user's scene experience.

[0031] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or be understood by implementing the present use information. The purpose and other advantages of the present invention can be realized and obtained by the structures pointed out in the description, claims and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0036] like Figure 1 The illustrated embodiment of a vehicle charging port lighting control system includes: a light and rain sensor, a body control module, a charging port lighting lamp, a charging port cover actuator, and a battery management system module.

[0037] Specifically, the light rainfall sensor is connected to the body control module through an on-board wired network, and is used to detect the intensity of external light, send out a signal of corresponding light intensity, and determine the light intensity threshold required to light up the charging port lighting.

[0038] The battery management system module is connected to the body control module via an on-vehicle wired network, and the collected connection status signal of the vehicle charging plug is sent to the body control module.

[0039] The charging port lighting is connected to the vehicle body control module through a common vehicle wiring harness, and the charging port lighting is directly driven by the body control module.

[0040] The charging port cover actuator is connected to the body control module through a common vehicle wiring harness, and the open or closed state of the vehicle charging port cover is fed back to the body module through a hard line.

[0041] Furthermore, the body control module and the battery management system are connected via a CAN (Controller Aera Network) bus; the light rain sensor and the body control module are connected via a LIN (Local Interconnect Network) line.

[0042] In some embodiments, Figure 2 A method for controlling the lighting of a car charging port is shown. When a user charges the vehicle according to the driving time or battery power requirements of the vehicle, if the vehicle is located in a dark environment, the light and rain sensor senses that the external light intensity is less than or equal to the threshold, the user opens the charging port cover, and the body control module controls the charging port cover to perform an opening action. The body control module collects the opening state of the charging port cover through hard-line feedback. If the charging port cover is open, the body control module drives the lighting lamp to light up, and it automatically turns off after a period of time. If the charging port cover changes from open to closed, the body control module immediately stops driving the charging port lighting lamp to light up; or when the user plugs in or unplugs the charging gun, the battery management system module sends the charging gun connection status to the body control module. If the charging gun changes from an inserted state to an unplugged state or from an unplugged state to an inserted state, the body control module controls the driving of the charging port lighting lamp to light up, and it automatically turns off after lighting up for a period of time. If the charging port cover updates the opening state to a closed state, the charging port lighting lamp immediately turns off.

[0043] In addition, if the vehicle is located in a bright environment, the light and rain sensor senses that the external light intensity is greater than the threshold, and the user opens the charging port cover, regardless of whether the charging port cover is open or not; or regardless of whether the charging gun is connected or not, the body control module will not drive the charging port lighting.

[0044] The modules used in the present invention include a light and rain sensor, a body control module, a charging port lighting lamp, a charging port cover actuator and a battery management system module, all of which are already components on the vehicle, thereby avoiding the increase of additional costs and improving the user experience.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
