[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0029] Figure 1 This is a flow chart of a vehicle light control method provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of automatically adjusting vehicle lights in advance. The method can be executed by a vehicle light control device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1 Said method comprises:

[0030] S110. Obtain road information ahead of the vehicle's current position based on smart sensors configured on the vehicle and / or cloud map data.

[0031] Among them, the intelligent sensor may be an Advanced Driving Assistance System (ADAS) sensor, for example, it may include at least one of sensors of the type of camera, millimeter wave radar, ultrasonic radar, etc. The cloud map data may be map data stored in a cloud server, and the map data may include road information corresponding to the vehicle's driving path. The cloud map data may be obtained from the cloud server through a telematics box (T-BOX). The road information ahead may be road information beyond a preset distance ahead of the current location of the vehicle. The preset distance may be set as required, and the road information may at least include the road type. Different road types may correspond to different road features. The road type may include at least one of the types of curves, uphills, tunnels, and emergency sections, and accordingly, the road features may include at least one of the features of curve features, slope features, tunnel entrance features, and emergency road conditions. The curve feature may be feature information for characterizing the direction of the turn and the radius of the turn. The slope feature may be feature information for characterizing the slope value of an uphill road, and the tunnel entrance feature may include feature information such as the outline of the tunnel entrance and light changes. The emergency road section may be a road section where a natural disaster occurs or a road section where a man-made traffic accident occurs. The emergency road condition characteristics include at least one of the road condition characteristic types such as mudslide, landslide, multi-vehicle collision accident, etc.

[0032] Specifically, the corresponding smart sensor can determine the corresponding road information based on the detection information obtained beyond the preset distance of the current position of the vehicle. The corresponding cloud map data can pre-store the road information on the corresponding vehicle's driving route. It is also possible to merge the road information ahead obtained based on the smart sensor and the road information ahead obtained based on the cloud map data, and filter out duplicate content to obtain the road information ahead of the current position of the vehicle.

[0033] S120. When it is determined that there is a preset road type in the road information ahead, determine the road characteristics and estimated arrival time corresponding to the preset road type; wherein the preset road type includes at least one of a curve, an uphill road, a tunnel, and an emergency section.

[0034] The preset road type may be a type of road that is preset. The estimated arrival time may be the time when the vehicle arrives at the preset road based on the current speed of the vehicle and the distance between the current position and the corresponding preset road type.

[0035] Specifically, if there is no corresponding preset road type in the road information ahead, the current status of each type of headlights in the vehicle can be controlled to remain unchanged.

[0036] S130. Before a preset time interval of the estimated arrival time, control the vehicle to adjust at least one type of headlights of the vehicle according to the road characteristics.

[0037] The preset time interval can be set according to needs or experience, and is not specifically limited here. The vehicle light type may include at least one, for example, may include at least one of a low beam, a high beam, a left turn signal, a right turn signal, a left front fog light, a right front fog light, a clearance light, a position light, and a hazard warning light.

[0038] Specifically, a mapping relationship between different road features and the on / off states corresponding to each type of headlight in the vehicle can be established in advance. Accordingly, when it is determined that there is a preset road type on the corresponding road ahead, the on / off states corresponding to each type of headlight can be matched based on the road features of the preset road type, and at a time point corresponding to a preset time interval before reaching the preset road type, each type of headlight in the corresponding vehicle is adjusted to the on / off state, so as to achieve adjustment of at least one type of headlight of the corresponding vehicle. The on / off states of each type of headlight corresponding to each road feature can be set as needed.

[0039] The technical solution of the embodiment of the present invention, through the intelligent sensors and / or cloud map data configured on the vehicle, can timely obtain the road type in front of the current position and estimate the corresponding arrival time when the vehicle is traveling at the current position, so that before a preset time interval of reaching the position of the corresponding road type in front, the corresponding at least one type of vehicle lights can be adjusted in advance to match the road characteristics corresponding to the road type, thereby helping to avoid the situation where the vehicle lights cannot quickly adapt to the driving scene due to the need to adjust the lights after entering the driving scene corresponding to the corresponding road type, thereby helping to further improve the safety of the driving process while reducing the driver's operations.

[0040] Figure 2A This is a flow chart of a vehicle light control method provided in the second embodiment of the present invention. This embodiment is further optimized based on the above embodiments. It should be noted that for the parts not described in detail in this embodiment, please refer to the relevant descriptions in other embodiments.

[0041] Furthermore, “controlling the vehicle to adjust at least one type of headlights of the vehicle according to the road characteristics” is refined into “if the preset road type is a curve, controlling the vehicle to adjust at least one type of headlights of the vehicle according to the curve direction and turning radius corresponding to the curve” to improve the control mechanism of the corresponding headlights.

[0042] refer to Figure 2A , the method specifically comprises the following steps:

[0043] S210: Obtain road information ahead of the vehicle's current position based on smart sensors configured on the vehicle and / or cloud map data.

[0044] The road information ahead of the current position of the corresponding vehicle can be obtained by the body domain controller module (BDCM) of the corresponding vehicle. Specifically, TBOX can receive the cloud map data in the cloud server, and send the road information ahead in the cloud map data to the body domain controller BDCM via the vehicle communication security gateway (Vehicle Communication Security, VCS).

[0045] S220. When it is determined that there is a preset road type in the road information ahead, determine the road characteristics and estimated arrival time corresponding to the preset road type; wherein the preset road type includes at least one of a curve, an uphill road, a tunnel, and an emergency section.

[0046] S230. Before the preset time interval of the estimated arrival time, if the preset road type is a curve, control the vehicle to adjust at least one type of headlights of the vehicle according to the curve direction and turning radius corresponding to the curve.

[0047] The road information may include the road type to which the corresponding road belongs and the road features corresponding to the road type. The direction of the curve may include left turn and right turn, etc. The turning radius may be the radius corresponding to the corresponding curve.

[0048] Specifically, a mapping relationship between different turning directions, turning radii and the corresponding on and off states of each type of headlight can be established in advance. Accordingly, after determining the corresponding turning direction and turning radius, the corresponding on and off states of each type of headlight can be matched by traversing the mapping relationship, and based on the on and off states of each type of headlight, at least one type of headlight can be controlled and adjusted to the switch state.

[0049] Exemplarily, controlling the vehicle to adjust at least one type of headlight of the vehicle according to the curve direction and turning radius corresponding to the curve may include:

[0050] If it is determined that the direction of the curve is a left turn and the turning radius is less than the set value, the turning light or fog light on the left side of the vehicle is controlled to be turned on, and the on and off status of the turning light or fog light is updated; if it is determined that the direction of the curve is a right turn and the turning radius is less than the set value, the turning light or fog light on the right side of the vehicle is controlled to be turned on, and the on and off status of the turning light or fog light is updated; if it is determined that the turning radius is greater than the set value, the vehicle's light adjustment is controlled to exit, and the current on and off status of each type of light in the vehicle remains unchanged.

[0051] The fog lamp may be used to replace the turning lamp when the vehicle is not equipped with a corresponding turning lamp.

[0052] It can be understood that when a vehicle turns left or right, by determining that the corresponding turning radius is less than a set value, the turning lights or fog lights on the corresponding side of the corresponding vehicle are further turned on to improve the lighting effect of the corresponding vehicle when turning, thereby helping to avoid the situation where the turning vision is too poor due to a large turning radius, and further helping to further improve the safety of the vehicle's turning process.

[0053] In an optional embodiment, controlling the vehicle to adjust at least one type of headlight of the vehicle according to the road characteristics may also include:

[0054] If the preset road type is an uphill, the vehicle is controlled to adjust at least one type of headlight of the vehicle according to the slope value corresponding to the uphill; if the preset road type is a tunnel, the vehicle is controlled to adjust at least one type of headlight of the vehicle according to the tunnel entrance characteristics corresponding to the tunnel; if the preset road type is an emergency section, the vehicle is controlled to adjust at least one type of headlight of the vehicle according to the road condition characteristics corresponding to the emergency section.

[0055] Among them, the road feature corresponding to the uphill road may be a slope value, the road feature corresponding to the tunnel may be a tunnel entrance feature, and the road feature corresponding to the emergency section may be a road condition feature.

[0056] It can be understood that by introducing the uphill slope value, the tunnel entrance characteristics of the tunnel and the road condition characteristics of the emergency section as a more specific basis for adjusting the corresponding headlights, it is possible to effectively avoid the situation where the adjusted headlight states are not sufficiently matched due to the corresponding headlight adjustments directly based on the determination of the road type, thereby helping to achieve targeted advance adjustments of lights for different road characteristics under the corresponding preset road types, and further helping to ensure that the corresponding vehicles can maintain good lighting effects under different road characteristics, thereby improving the safety of the corresponding driving process.

[0057] Exemplarily, controlling the vehicle to adjust at least one type of headlight of the vehicle according to the slope value corresponding to the uphill slope may include:

[0058] According to the slope value corresponding to the uphill slope, the target lighting angle of the vehicle headlight is determined; according to the target lighting angle and the initial lighting angle of the vehicle headlight, the angle to be adjusted of the vehicle headlight is determined; according to the angle to be adjusted, the drive motor corresponding to the vehicle headlight is controlled to perform pitch adjustment.

[0059] Among them, the target lighting angle can be the lighting angle at which the vehicle has the best lighting effect on the corresponding uphill section. The initial lighting angle can be the lighting angle of the vehicle headlight before adjustment. The lighting angle can be the angle at which the vehicle headlight illuminates upward or downward. The drive motor can include a left headlight height adjustment motor and a right headlight height adjustment motor, etc. The left headlight height adjustment motor can be used to increase the lighting height of the headlight on the left side of the vehicle, and the right headlight height adjustment motor can be used to increase the lighting height of the headlight on the right side of the vehicle. The higher the lighting height, the larger the lighting angle of the vehicle headlight can be.

[0060] Specifically, a database of mapping relationships between different slope values ​​and target lighting angles of vehicle headlights can be established in advance. Accordingly, after determining the slope value of the corresponding uphill slope, the database of mapping relationships is traversed to match the corresponding target lighting angle, and the matched target lighting angle is used as the target lighting angle of the vehicle headlight on the uphill slope. Based on this, the difference between the target lighting angle and the corresponding initial lighting angle can be used as the corresponding angle to be adjusted, and the corresponding drive motor can be controlled to perform pitch adjustment based on the angle to be adjusted, so that the adjusted lighting angle of the corresponding vehicle headlight is the corresponding target lighting angle.

[0061] It can be understood that by determining the target lighting angle of the vehicle headlight according to the slope value, and controlling the corresponding drive motor to perform pitch adjustment on the vehicle headlight based on the angle to be adjusted corresponding to the difference between the target lighting angle and the initial lighting angle of the vehicle headlight, the pitch angle of the corresponding vehicle headlight after adjustment can be accurately matched with the uphill section, thereby helping to produce a better lighting effect on the uphill section, which is of great significance to improving driving safety on the uphill section.

[0062] Exemplarily, controlling the vehicle to adjust at least one type of headlight of the vehicle according to the tunnel entrance characteristics corresponding to the tunnel may include:

[0063] According to the tunnel entrance characteristics corresponding to the tunnel, the set light type outside the vehicle is controlled to be turned on, and the light types inside the vehicle are controlled to be adjusted based on a preset tunnel lighting mode; wherein the set light type includes at least one of a position light, a clearance light and a low beam light.

[0064] Specifically, when the corresponding tunnel entrance characteristics meet the set conditions, the operation of adjusting the external and internal lights of the vehicle can be performed respectively. The set condition can be that the degree of change of the light at the corresponding tunnel entrance relative to the light outside the tunnel is greater than a set threshold. The various types of lights in the vehicle can include at least one of the types of ceiling lights, reading lights, and instrument lights. The preset tunnel lighting mode corresponds to the preset on / off status of each type of light in the vehicle, and the on / off status of each type of light in the vehicle under different tunnel lighting modes is different.

[0065] It can be understood that by determining the corresponding tunnel entrance characteristics and adjusting the corresponding vehicle's internal and external lights based on the tunnel entrance characteristics, it can be ensured that after entering the tunnel, the vehicle's internal and external lights can adapt to the lighting conditions in the corresponding tunnel, which can avoid the situation where the driver cannot accurately obtain the vehicle driving information due to poor interior lighting effects caused by only adjusting the vehicle's external lights, thereby helping to further improve the safety of the corresponding vehicle during tunnel driving.

[0066] In an optional embodiment, the corresponding method may further include:

[0067] An estimated time of departure of the vehicle from the tunnel is determined, and before a set time interval of the estimated time of departure, a set light type outside the vehicle and the tunnel lighting mode are controlled to be turned off.

[0068] The estimated departure time may be the time when the vehicle leaves the tunnel exit, calculated based on the current driving speed of the vehicle and the distance between the current position of the vehicle and the tunnel exit.

[0069] It can be understood that by determining the preset departure time of the corresponding vehicle in the tunnel and controlling to turn off the set light type on the outside of the vehicle and the tunnel lighting mode before the set time interval of the expected departure time, the various light types inside and outside the vehicle turned on before entering the tunnel can be timely controlled when the vehicle has good lighting conditions before exiting the tunnel, thereby helping to avoid waste of resources caused by continuous lighting of the corresponding vehicle.

[0070] In an optional embodiment, the road condition feature may include the presence of a natural disaster or a man-made traffic accident. Accordingly, controlling the vehicle to adjust at least one type of headlight of the vehicle according to the road condition feature corresponding to the emergency road section may include:

[0071] According to the road condition characteristics corresponding to the emergency section, the hazard warning lights of the vehicle are controlled to be turned on, and the hazard warning lights are turned off after the switch of the hazard warning lights is manually triggered or the vehicle is turned off.

[0072] Specifically, when it is determined that the road condition characteristics corresponding to the emergency section are natural disasters or man-made traffic accidents, the corresponding hazard warning lights can be controlled to be turned on.

[0073] It is understandable that, by automatically controlling the opening of the corresponding hazard warning lights when it is determined that the corresponding emergency road section is a natural disaster or a man-made traffic accident, it is possible to achieve a predictive reminder of the corresponding emergency road section, so that other vehicles can pay attention to the road conditions ahead in advance, thereby helping to avoid rear-end collisions due to the failure of the following vehicle to slow down in time, and further improving the safety of the corresponding driving process. In addition, by turning off the corresponding hazard warning lights after the switch of the hazard warning lights is manually triggered or the vehicle is turned off, it is possible to avoid the situation where the hazard warning lights are automatically turned off too early when the vehicle is not turned off, resulting in the inability to continuously provide danger reminders for the corresponding emergency road conditions, thereby also helping to further improve driving safety.

[0074] In an optional embodiment, the corresponding method may further include:

[0075] When adjusting at least one type of headlight of the vehicle, a corresponding prompt box is generated in the instrument panel and displays the current on / off state of each adjusted headlight, wherein the on / off state may correspond to the above-mentioned on / off state.

[0076] It can be understood that by generating a corresponding prompt box in the instrument panel and displaying the on and off status of the adjusted lights when adjusting the corresponding lights, the corresponding driver can promptly know that the current status of the vehicle's lights has been switched without his own operation and the specific on and off status under the status switch, thereby avoiding the situation where the driver manually adjusts the corresponding switch of the corresponding light because he is not aware that the lights have been automatically adjusted in advance, causing the lights to switch states again. This helps to eliminate the safety hazards caused by the driver's manual re-adjustment of the corresponding lights, and further improves the corresponding driving safety.

[0077] In an optional embodiment, the corresponding method may further include: in response to a light control operation on the vehicle central control screen, controlling to turn on or off the above-mentioned control function of the corresponding vehicle light. The light control operation may be triggered by the driver based on an enable switch in the central control screen, and the enable switch may be in the form of a soft switch.

[0078] In an embodiment of the present invention, by controlling and adjusting at least one type of headlights of the corresponding vehicle based on the turning direction and turning radius of the curve itself before a preset time interval when the vehicle reaches the corresponding curve, the adjustment of the corresponding headlights can be made more in line with the actual characteristics of the corresponding curve, which helps to avoid the situation where the adjustment of the corresponding headlights does not match the corresponding curve well and causes poor lighting effects, thereby helping to improve the adaptability of the advance adjustment of the corresponding lights on the curve, and further helping to ensure the lighting effect of the vehicle when driving in the corresponding curve, thereby improving the safety of the driving process.

[0079] For easier understanding, please refer to Figure 2B A specific example of a predictive lighting control system is provided. It should be noted that the Figure 2B The various components included in the corresponding systems involved are only for illustrative purposes and should not be construed as specific limitations of the present invention.
