[0080] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0081] Reference Figure 1 The diagram illustrates a flowchart of an auxiliary lighting method according to an embodiment of the present invention, applied to a vehicle, and may include the following steps:

[0082] Step 101: When an auxiliary lighting event is detected, acquire the target ambient light intensity;

[0083] The auxiliary lighting event may include at least one of the following: the target user gets out of the vehicle; the target user enters the preset range of the vehicle; or the auxiliary lighting command generated after the target user performs a user operation.

[0084] The target user can refer to a user associated with the vehicle, such as the driver of the vehicle, a user getting out of the vehicle, etc. This embodiment of the invention does not limit this.

[0085] The preset range can be relative to the vehicle; specifically, the preset range of the vehicle can be divided with the vehicle as the center and the preset value as the radius.

[0086] User operation refers to the operation performed by a user on the vehicle or mobile device when the auxiliary lighting function of the vehicle is needed; the vehicle or mobile device may generate an auxiliary lighting command in response to the user operation performed by the user.

[0087] If a mobile device generates the auxiliary lighting command, the mobile device can send the generated auxiliary lighting command to the vehicle to trigger the auxiliary lighting event.

[0088] As an example, when a target user is detected getting out of the vehicle, it can indicate that an auxiliary lighting event has been triggered.

[0089] As another example, when a target user is detected entering a preset range of the vehicle, it can also indicate that an auxiliary lighting event has been triggered.

[0090] As another example, when it is detected that the vehicle has generated an auxiliary lighting command, or when the vehicle receives an auxiliary lighting command, it can also indicate that an auxiliary lighting event has been detected.

[0091] In practical applications, target users only need auxiliary lighting when the ambient light intensity is low; therefore, when an auxiliary lighting event is detected, the target ambient light intensity can be obtained first to determine whether auxiliary lighting function needs to be provided to the target user.

[0092] Step 102: When the ambient light intensity of the target is lower than the preset light intensity threshold, obtain the target location of the target user;

[0093] If the ambient light intensity is higher than a preset light intensity threshold, it means that the target user can see the surrounding environment clearly using the ambient light; in this case, auxiliary lighting need not be provided to the target user. The preset light intensity threshold can be set according to actual conditions or based on the target user's settings; this embodiment of the invention does not impose any limitations on this.

[0094] If the ambient light intensity is lower than the preset light intensity threshold, it means that the target user cannot see the surrounding environment clearly by relying solely on ambient light. In this case, in order to help the target user see the surrounding environment clearly, auxiliary lighting can be provided to the target user.

[0095] Specifically, the target user's target location can be obtained first, and then auxiliary lighting function can be provided to the target user through the following steps 103-104.

[0096] Step 103: Determine the corresponding target auxiliary lighting strategy based on the target location;

[0097] The target-assisted lighting strategy may include at least one of the following: a first strategy for adjusting the lighting brightness; and a second strategy for adjusting the lighting angle.

[0098] In practical applications, the required lighting brightness and lighting angle will vary depending on the target user's position relative to the vehicle. Therefore, after obtaining the target user's target position, the target lighting strategy corresponding to the target position can be determined first.

[0099] For example, if the target user's target location is at an angle that the vehicle's lights cannot reach, the vehicle's lights can be controlled by determining a second strategy to adjust the lighting angle so that the vehicle's lights can reach the target location; if the target user's target location gradually moves away from the vehicle, the vehicle's lights can be controlled by determining a first strategy to adjust the lighting brightness so that the light intensity at the target location exceeds a preset light intensity threshold.

[0100] Step 104: Control the vehicle's lighting fixtures according to the target auxiliary lighting strategy.

[0101] After determining the target auxiliary lighting strategy corresponding to the target location, the vehicle's lighting fixtures can be controlled according to the target auxiliary lighting strategy; for example, if it is the first strategy, the brightness of the vehicle's lighting fixtures can be adjusted; if it is the second strategy, the lighting angle of the vehicle's lighting fixtures can be adjusted. This embodiment of the invention does not limit this.

[0102] In this embodiment of the invention, upon detecting a triggering auxiliary lighting event, the target ambient light intensity can be obtained first; when the target ambient light intensity is lower than a preset light intensity threshold, the target user's target location is obtained; based on the target location, a corresponding target auxiliary lighting strategy is determined; and based on the target auxiliary lighting strategy, the vehicle's lighting fixtures are controlled. Through this embodiment of the invention, automatic auxiliary lighting adapted to the user's location is achieved when ambient light intensity is weak, enabling the user to see the environment clearly even in low-light conditions with the help of vehicle auxiliary lighting.

[0103] Reference Figure 2 The diagram illustrates a flowchart of another auxiliary lighting method according to an embodiment of the present invention, which may include the following steps:

[0104] Step 201: When an auxiliary lighting event is detected, acquire the target ambient light intensity;

[0105] When a user triggers an auxiliary lighting event, the target ambient light intensity can be obtained first. Specifically, the target ambient light intensity can be obtained through a light sensor deployed on the vehicle, but this embodiment of the invention does not limit this.

[0106] As an example, before obtaining the target ambient light intensity, it can be determined whether the vehicle is in a preset gear, such as P gear; if the vehicle is in the preset gear, then the target ambient light intensity is obtained; otherwise, the process ends.

[0107] Step 202: When the ambient light intensity of the target is lower than the preset light intensity threshold, obtain the target location of the target user;

[0108] After obtaining the target ambient light intensity, the target ambient light intensity can be compared with the preset light intensity threshold. If the target ambient light intensity is lower than the preset light intensity threshold, it means that the target user cannot see the surrounding environment clearly by relying solely on ambient light.

[0109] At this point, the target user's location can be obtained first to provide the user with precise auxiliary lighting.

[0110] In one embodiment of the present invention, the vehicle can establish a connection with a target mobile device carried by the target user, which can be a mobile phone, car key, wearable device, etc.; the target user's target location can be obtained through the following sub-steps:

[0111] Sub-step 11: Receive the target signal sent by the target mobile device;

[0112] First, the vehicle can receive target signals sent by the target mobile device; the target signals may include positioning information generated by the target mobile device based on the navigation system.

[0113] Sub-step 12: Determine the target user's target location based on the target signal.

[0114] Then, the target user's target location can be determined based on the target signal.

[0115] As an example, the target user's position relative to the vehicle can be determined directly based on the positioning information of the target signal.

[0116] As another example, the target user's position relative to the vehicle can also be determined based on the strength of the target signal or the transmission time. Specifically, triangulation technology can be used to determine the target user's position relative to the vehicle.

[0117] In practical applications, the target location is actually determined based on the target mobile device. Since the target mobile device is usually located in the target user's hand, pocket, or backpack, rather than above the target user's head, the target location actually corresponds to the area below the target user's head. When determining the target auxiliary lighting strategy based on this target location, the vehicle's headlights can be kept away from shining directly on the target user's head, thereby avoiding discomfort that the target user might experience due to direct illumination of the target user's face.

[0118] In another embodiment of the present invention, the target location of the target user can also be located based on radar equipment, camera equipment, etc. on the vehicle, and the present invention does not limit this.

[0119] Step 203: When the target auxiliary lighting strategy includes the first strategy, obtain the target environment fog level;

[0120] In practical applications, if the target auxiliary lighting strategy includes the first strategy, the target environment fog level can be obtained first; the target environment fog level can be monitored by temperature and humidity sensors deployed in the vehicle.

[0121] Step 204: Determine the target illumination brightness based on the target ambient light intensity, target ambient fog level, and target location;

[0122] In practical applications, the light intensity of light will vary with the illumination distance and the ambient fog level; for example, the light intensity of light emitted by the same illumination brightness will be different at 10m and 20m.

[0123] Therefore, in order to ensure that the auxiliary lighting delivered to the target location is sufficient for the target user to see the environment, the correspondence between the ambient fog level and distance and the lighting brightness can be preset. This correspondence can characterize the value by which the light emitted by the vehicle's lights at a certain brightness can increase the light intensity of the corresponding environment at a certain location under a certain ambient fog level and distance.

[0124] After determining the target ambient light intensity, target ambient fog level, and target location, the target illumination brightness corresponding to the distance from the target ambient light intensity, target ambient fog level, and target location can be determined based on the above correspondence.

[0125] As an example, the light intensity difference between the preset light intensity threshold and the target ambient light intensity can be determined first; then, based on the light intensity difference, the target ambient fog level, and the distance to the target location, the corresponding target illumination brightness can be found from the above correspondence.

[0126] In one embodiment of the present invention, after determining the target illumination brightness, the following steps may be further included:

[0127] Determine whether the target illumination brightness exceeds a preset brightness threshold; if the target illumination brightness exceeds the preset brightness threshold, re-execute the step of acquiring the target ambient light intensity.

[0128] In practical applications, the target lighting brightness may be too high due to insufficient ambient light intensity, excessive distance, or excessive ambient fog. If an excessively high target lighting brightness is used to determine the first strategy, it may cause the light emitted by the lighting fixtures to be too bright when controlling the lighting fixtures, resulting in user discomfort.

[0129] At this time, in order to avoid causing inconvenience to users due to excessive brightness of the light emitted by the lighting fixtures, after determining the target lighting brightness, it can be first determined whether the target lighting brightness exceeds a preset brightness threshold. The preset brightness threshold can be set according to the actual situation or by the user. This embodiment of the invention does not limit this.

[0130] If it is determined that the target illumination brightness does not exceed the preset brightness threshold, then step 205 can be executed.

[0131] If the target illumination brightness is determined to exceed the preset brightness threshold, step 205 can be skipped and the auxiliary lighting function can be exited; alternatively, the step of obtaining the target ambient light intensity can be re-executed. This embodiment of the invention does not limit this.

[0132] Step 205: Determine the first strategy based on the target illumination brightness;

[0133] After determining the target illumination brightness, a first strategy that can achieve the target illumination brightness can be generated based on the target illumination brightness.

[0134] In one embodiment of the present invention, step 205 can be implemented by the following sub-steps:

[0135] Sub-step 21: Determine the first target lighting fixture to be turned on based on the target lighting brightness;

[0136] In practical applications, a vehicle can be equipped with multiple lighting fixtures; after determining the target lighting brightness, at least one first target lighting fixture to be turned on can be selected from the multiple lighting fixtures; after being turned on, the at least one first target lighting fixture can achieve the target lighting brightness determined above.

[0137] Sub-step 22: Determine the first target light point to be turned on based on the target illumination brightness;

[0138] In practical applications, the lighting fixtures deployed in a vehicle may include multiple light points; after determining the target lighting brightness, at least one first target light point to be turned on can be selected from the multiple light points; after being turned on, the at least one first target light point can achieve the target lighting brightness determined above.

[0139] Sub-step 23: Determine the target input power of the vehicle's lighting fixtures based on the target illumination brightness;

[0140] In practical applications, the lighting fixtures deployed in vehicles can be lighting fixtures with adjustable input power; after determining the target lighting brightness, the corresponding target input power can be determined based on the target lighting brightness; this target input power can ensure that the vehicle's lighting fixtures can achieve the aforementioned determined target lighting brightness after being turned on.

[0141] As an example, sub-step 24 can be executed after one or more of the above sub-steps 21-23, and this embodiment of the invention does not limit this.

[0142] Sub-step 24: Determine the first strategy based on the first target lighting fixture and / or the first target light point and / or the target input power.

[0143] After determining the first target lighting fixture and / or the first target light spot and / or the target input power, a corresponding first strategy can be formulated based on the first target lighting fixture and / or the first target light spot and / or the target input power.

[0144] Step 206: Control the vehicle's lighting fixtures according to the first strategy;

[0145] After determining the first strategy corresponding to the target location, the vehicle's lighting fixtures can be controlled according to the target auxiliary lighting strategy.

[0146] Specifically, after determining the first strategy corresponding to the target location, the vehicle's lighting fixtures can be controlled according to the first strategy.

[0147] As an example, the first target lighting fixture can be turned on according to the first strategy.

[0148] As another example, the first target light point can also be activated according to the first strategy.

[0149] As another example, the vehicle's lights can also be turned on according to the first strategy, and a target input power can be supplied to the vehicle's lights.

[0150] Step 207: When controlling the vehicle's lighting fixtures, determine the target scene corresponding to the target location, and determine the target auxiliary lighting off conditions corresponding to the target scene;

[0151] In practical applications, to reduce unnecessary waste of resources, vehicle lights can be turned off when the user does not need to use auxiliary lighting.

[0152] Specifically, when controlling the vehicle's lighting fixtures according to the first strategy, a target scene corresponding to the target location can be determined; the target scene can be, for example, a residential area, outdoors, a park, an underground parking lot, etc.

[0153] Then, the target auxiliary lighting off conditions can be determined in advance for the target scene; for example, the auxiliary lighting off conditions of "the user is 10m away from the vehicle" and "auxiliary lighting is on for 10 minutes" can be set for outdoor scenes; the auxiliary lighting off conditions of "the user is 20m away from the vehicle" and "auxiliary lighting is on for 1 minute" can also be set for residential scenes. The embodiments of the present invention do not limit this.

[0154] Step 208: Determine the target distance of the target user relative to the vehicle based on the target location;

[0155] Then, based on the target location, the target distance of the target user relative to the vehicle can be determined, so as to determine whether the target user still needs to use the auxiliary lighting function based on the target distance.

[0156] Step 209: When the target distance meets the target auxiliary lighting off condition, and / or when the duration of the vehicle's lights on meets the target auxiliary lighting off condition, turn off the vehicle's lights.

[0157] When determining the target distance, the duration for which the vehicle's lights have been on can also be recorded. Then, by judging whether the target distance and / or the duration for which the vehicle's lights have been on meet the target auxiliary lighting off conditions, it can be determined whether auxiliary lighting still needs to be provided to the target user.

[0158] If the target distance and / or the duration for which the vehicle's lights have been on meet the conditions for turning off the auxiliary lighting, the vehicle's lights can be turned off; otherwise, the vehicle's lights should remain on.

[0159] In this embodiment of the invention, upon detecting a triggering auxiliary lighting event, the target ambient light intensity can be acquired first; when the target ambient light intensity is lower than a preset light intensity threshold, the target user's target location is acquired; when the target auxiliary lighting strategy includes a first strategy, the target ambient fog level is acquired; based on the target ambient light intensity, target ambient fog level, and target location, the target lighting brightness is determined; based on the target lighting brightness, the first strategy is determined; based on the first strategy, the vehicle's lighting fixtures are controlled; when controlling the vehicle's lighting fixtures, a target scene corresponding to the target location is determined, and a target auxiliary lighting off condition corresponding to the target scene is determined; based on the target location, the target distance of the target user relative to the vehicle is determined; when the target distance meets the target auxiliary lighting off condition, and / or when the duration of the vehicle's lighting fixtures being on meets the target auxiliary lighting off condition, the vehicle's lighting fixtures are turned off. Through this embodiment of the invention, more accurate auxiliary lighting is provided to the user based on the current environmental conditions.

[0160] Furthermore, when providing auxiliary lighting to users, the system automatically turns off the auxiliary lighting based on the user's current scene, reducing unnecessary waste of resources.

[0161] Reference Figure 3 The diagram illustrates a flowchart of another auxiliary lighting method according to an embodiment of the present invention, which may include the following steps:

[0162] Step 301: When an auxiliary lighting event is detected, acquire the target ambient light intensity;

[0163] When a user triggers an auxiliary lighting event, the light sensor deployed on the vehicle can first detect the light intensity in the environment to obtain the target ambient light intensity.

[0164] Step 302: When the ambient light intensity of the target is lower than the preset light intensity threshold, obtain the target location of the target user;

[0165] After obtaining the target ambient light intensity, the target ambient light intensity can be compared with the preset light intensity threshold. If the target ambient light intensity is lower than the preset light intensity threshold, it means that the target user cannot see the surrounding environment clearly by relying solely on ambient light. In this case, the target user's target location can be obtained first to provide the user with accurate auxiliary lighting.

[0166] Step 303: When the target auxiliary lighting strategy includes a second strategy, determine the first relative angle between the target user and the second target lighting fixture based on the target location; the first relative angle is not greater than the adjustable range of the second target lighting fixture.

[0167] The vehicle's lighting fixtures can rotate up, down, left, and right; there may be multiple lighting fixtures, each with an adjustable range.

[0168] In practical applications, since the adjustment range of each lighting fixture is limited, the relative angle between the target user and each lighting fixture can be determined first. Then, the lighting fixture whose relative angle is not greater than the adjustable range of the corresponding lighting fixture is used as the second target lighting fixture, and the relative angle is used as the first relative angle.

[0169] Specifically, a coordinate system can be established for the vehicle; then the coordinates of each lighting fixture in the vehicle (DL1X, DL1Y, DL1Z), (DL2X, DL2Y, DL2Z)...(DLNX, DLNY, DLNZ) can be determined, as well as the coordinates (x0, y0, z0) corresponding to the target position.

[0170] Then, the left-right relative angle θ between the target user and the first lighting fixture (DL1X, DL1Y, DL1Z) can be calculated as arctan(y0-DL1Y) / (x0-DL1X), and the up-down relative angle α between the target user and the lighting fixture can be calculated as arc(z0-DL1Z) / ((x0-DL1X)^2+(y0-DL1Y)^2)^1 / 2.

[0171] Next, the left-right relative angle θ and the up-down relative angle α can be used as the relative angle between the lighting fixture and the target user. After determining the relative angle, it can be judged whether the relative angle exceeds the adjustable range of the lighting fixture. If it does not exceed the range, the lighting fixture can be used as the second target lighting fixture, and the relative angle corresponding to the lighting fixture can be used as the first relative angle. If it exceeds the range, the relative angle between the next lighting fixture and the target user can be calculated.

[0172] Step 304: Determine the second strategy based on the first relative angle;

[0173] After determining the first relative angle, a second strategy for adjusting the angle of the second target lighting fixture can be determined based on the first relative angle.

[0174] For example, if the first relative angle is 15° to the left of the horizontal, a second strategy of adjusting 15° to the left in the horizontal direction can be generated. This embodiment of the invention does not limit this.

[0175] Step 305: Control the lighting fixtures of the second target according to the second strategy.

[0176] After determining the second strategy, the illumination angle of the second target lighting fixture can be adjusted according to the second strategy; specifically, the second target lighting fixture can be rotated up and down or left and right according to the second strategy.

[0177] In one embodiment of the present invention, the following steps may also be included:

[0178] Based on the target location, determine the second relative angle between the target user and the vehicle; based on the second relative angle and the adjustable range of the vehicle's lighting fixtures, adjust the vehicle's posture.

[0179] In practical applications, the relative angle between all lighting fixtures and the target user may exceed the adjustable range of the corresponding lighting fixtures; in this case, the illumination range of the lighting fixtures can be adjusted by adjusting the vehicle's posture.

[0180] Specifically, the second relative angle between the target user and the vehicle can be determined first based on the target location; for example, the second relative angle between the target user and the vehicle can be determined based on the vehicle's position and the target location.

[0181] Then, the vehicle's attitude can be adjusted according to the second relative angle and the adjustable range of the vehicle's lighting fixtures; for example, if the second relative angle is θ1 and the adjustable range of the lighting fixtures is 0-θ2, and θ1 is greater than θ2, then the vehicle's attitude can be adjusted to any attitude in [θ1-θ2, θ1+θ2] so that the vehicle's lighting fixtures can illuminate the target position.

[0182] In another embodiment of the present invention, the vehicle can be controlled to drive to a suitable position for auxiliary lighting, and after the auxiliary lighting ends, the vehicle can be controlled to automatically return to the previously parked position. The present invention does not limit this.

[0183] For example, a vehicle can be controlled to drive onto a slope to raise or lower the illumination range of the lighting fixtures; or, a vehicle can be controlled to follow a target user to provide auxiliary lighting.

[0184] As an example, if a first strategy is also determined, the second target lighting fixture can be controlled simultaneously in conjunction with the first strategy. This embodiment of the invention does not limit this.

[0185] like Figure 4 First, it can detect whether the user has performed a user operation on the auxiliary lighting function button; if it is detected that the user has performed a user operation on the auxiliary lighting function button, it can then detect whether the vehicle is currently in P gear.

[0186] When the vehicle is in P gear, it can detect whether the target user is outside the vehicle; when the target user is detected to be outside the vehicle, it can obtain the target ambient light intensity and determine whether the target ambient light intensity is lower than the preset light intensity threshold.

[0187] If the ambient light intensity of the target is lower than the preset light intensity threshold, the user's current scene can be determined based on the target location.

[0188] When the scene is a residential area, the distance between the target user and the vehicle can be determined based on the target location. If the distance is less than 20m, the target lighting brightness can be determined first, and it can be determined whether adjusting the brightness of the lighting fixtures and the illumination angle of the lighting fixtures can increase the ambient light intensity of the target location to a level higher than the preset light intensity threshold.

[0189] If the ambient light intensity at the target location can be increased to a level higher than the preset light intensity threshold, the brightness of the lighting fixtures and the illumination angle of the lighting fixtures will be adjusted to provide auxiliary lighting to the user. The auxiliary lighting function will be stopped when the auxiliary lighting off conditions set for residential areas are met.

[0190] If the ambient light intensity at the target location cannot be increased to a level higher than the preset light intensity threshold, then it is determined whether the vehicle's posture can be adjusted to call upon lighting fixtures at other locations for auxiliary illumination.

[0191] Among them, ADAS (Advanced Driving Assistance System) can first determine whether the vehicle's attitude can be adjusted in the current environment; if so, it will then adjust the vehicle's attitude.

[0192] If the current scene is not a residential area, the target lighting brightness can be determined first, and it can be judged whether adjusting only the brightness of the lighting fixtures and the illumination angle of the lighting fixtures can increase the ambient light intensity of the target location to a level higher than the preset light intensity threshold.

[0193] If the ambient light intensity at the target location can be increased to a level higher than a preset light intensity threshold, the brightness of the lighting fixtures and the illumination angle of the lighting fixtures will be adjusted to provide auxiliary lighting to the user. The auxiliary lighting function will be stopped when the auxiliary lighting conditions set for non-residential areas are met.

[0194] If the ambient light intensity at the target location cannot be increased to a level higher than the preset light intensity threshold, then it is determined whether the vehicle's posture can be adjusted to call upon lighting fixtures at other locations for auxiliary illumination.

[0195] like Figure 5 The vehicle can be equipped with ADAS, in-vehicle entertainment control center, T-Box, positioning controller, body controller, multiple lighting control motors, multiple lighting adjusters, light sensor and temperature and humidity sensor; they can communicate with each other through LIN, CAN, Ethernet and other means.

[0196] ADAS can determine whether the parking area presents a possibility for changing the vehicle's posture and actively adjust the vehicle's orientation based on the angle calculation results. After adjustment, it actively restores the vehicle's posture.

[0197] The in-vehicle entertainment control center can use the vehicle's cameras and navigation information to determine whether the surrounding environment allows for proactive adjustments to the vehicle's attitude. Additionally, the in-vehicle navigation system can pinpoint the vehicle's parking location and differentiate the current environment.

[0198] The T-Box serves as a connection channel between the vehicle and the target mobile device, transmitting data between the two devices.

[0199] The positioning controller can perform positioning by controlling the field strength or the time difference between the vehicle's antenna and the target mobile device's antenna.

[0200] The vehicle controller can determine whether the current ambient light intensity exceeds a preset light intensity threshold based on the ambient light intensity collected by the light sensor; calculate the illumination direction of the lighting fixtures based on the location of the target mobile device and the location of each lighting fixture; and control the lighting fixtures to turn on, angle, and turn off.

[0201] Lighting control motors can be used to control the up, down, left, and right rotation of lighting fixtures.

[0202] Lighting regulators can be used to adjust the brightness, on / off state, and other functions of lighting fixtures.

[0203] Light sensors can be used to detect the intensity of light in the environment.

[0204] Temperature and humidity sensors can be used to detect fog levels in the air.

[0205] In this embodiment of the invention, upon detecting a triggering auxiliary lighting event, the target ambient light intensity can be acquired first. When the target ambient light intensity is lower than a preset light intensity threshold, the target user's target position is acquired. When the target auxiliary lighting strategy includes a second strategy, a first relative angle between the target user and the second target lighting fixture is determined based on the target position. The first relative angle is not greater than the adjustable range of the second target lighting fixture. The second strategy is determined based on the first relative angle. The second target lighting fixture is then controlled according to the second strategy. Through this embodiment of the invention, when the vehicle's lighting fixtures cannot provide auxiliary lighting to the user due to angle limitations, auxiliary lighting can be provided to the user by rotating the lighting fixtures.
