[0064] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0066] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0067] Example 1

[0068] See also Figure 1 , is a flow chart of an embodiment of the intelligent vehicle light system control method provided by the present invention, the method comprises steps 101 to 105, each step is specifically as follows:

[0069] Step 101: receiving an unlock request, and obtaining an unlock triggering method and a door lock detection result.

[0070] Further, in the first embodiment of the present invention, receiving an unlock request and obtaining an unlock trigger mode and a door lock detection result are specifically as follows:

[0071] Receiving an unlock request, and obtaining an unlock triggering method by parsing the unlock request;

[0072] Determine the position information of unlocking the doors according to the door lock status of each door;

[0073] Determining a door opening method for unlocking a door according to a detection result of a camera;

[0074] The position information of unlocking the door and the door opening method are determined as the door lock detection result.

[0075] In the first embodiment of the present invention, the intelligent vehicle lighting system includes four welcoming modes, corresponding to the four situations of driver getting on the vehicle, driver getting off the vehicle, passenger getting off the vehicle and passenger getting on the vehicle, and the corresponding welcoming modes are triggered when the vehicle door is unlocked. The unlocking triggering mode and the door lock detection result can determine different welcoming situations, thereby triggering different welcoming modes. Therefore, when a door lock request is received, it can be determined which welcoming mode is triggered by analyzing the unlocking triggering mode and the door lock detection result.

[0076] Optionally, the unlocking triggering methods include digital key triggering and interior door lock switch triggering. The door lock detection result can tell whether the door that triggers unlocking is the driver's side or the passenger's side, and whether the door is opened from the inside or the outside. Based on different unlocking triggering methods and door lock detection results, the corresponding welcoming situation of the current unlocking can be determined, thereby determining the welcoming method.

[0077] Optionally, the door lock detection result can be obtained by setting a camera to detect the way the unlocked door is opened, thereby determining different welcoming methods; or a sensor can be set on the door handle. When the inner or outer door handle is pulled, the sensor feedbacks information based on the sensed signal, thereby determining the door opening method, and then determining different welcoming methods.

[0078] Step 102: Determine a welcoming method according to the unlocking triggering method and the door lock detection result.

[0079] Further, in the first embodiment of the present invention, the welcoming mode is determined according to the unlocking trigger mode and the door lock detection result, specifically:

[0080] When the unlocking trigger mode is triggered by the digital key, the welcoming mode is determined as the driver getting on the vehicle;

[0081] When the unlocking trigger mode is triggered by the interior door lock switch, and the door lock detection result is that the unlocked door is the driver's side door and the door opening mode is opened from the interior, the welcoming mode is determined to be the driver getting off the vehicle;

[0082] When the unlocking trigger mode is triggered by the interior door lock switch, and the door lock detection result is that the unlocked door is the passenger door and the door opening mode is opened from the interior, the welcoming mode is determined to be passenger getting off the vehicle;

[0083] When the unlocking triggering mode is triggered by the door lock switch inside the vehicle, and the door lock detection result is that the unlocked door is the passenger side door and the door opening mode is opened from the outside of the vehicle, it is determined that the welcoming mode is for passengers to get on board.

[0084] In the first embodiment of the present invention, according to different combinations of unlocking triggering methods and door lock detection results, it is possible to identify which welcoming situation the current unlocking corresponds to. Specifically, if the unlocking request is triggered by a digital key, it means that the driver is outside the car, and at this time it can be confirmed that the welcoming method of the headlights is that the driver is getting on the car. If the unlocking request is triggered by the door lock switch inside the car, the door is unlocked by analyzing the door lock detection results, thereby determining which welcoming situation the current situation belongs to. If the door lock switch inside the car triggers the unlocking, and the door lock detection result is that the driver's side door is unlocked and the door is opened from inside the car, it is determined that the driver is in the car, and the current unlocking is triggered by the driver's side door, indicating that the current corresponding welcoming situation is that the driver is getting off the car. If the door lock switch inside the car triggers the unlocking, and the door lock detection result is that the passenger side door is triggered, it is further analyzed whether the current door is opened from inside or outside the car. If it is detected that the passenger-side door is opened from inside the car, it means that the passenger is in the car, and the welcoming method triggered at this time is for the passenger to get off the car; if it is detected that the passenger-side door is opened from outside the car, it means that the passenger is outside the car, and the welcoming method triggered at this time is for the passenger to get on the car.

[0085] Optionally, when the unlocking trigger mode is triggered by the interior door lock switch, and the door lock detection result is four-door unlocking, the driver's side door and the passenger's side door are opened from the inside of the car at the same time, and the welcoming mode is determined to be the driver getting off the car. When the unlocking trigger mode is triggered by the interior door lock switch, and the door lock detection result is four-door unlocking, the passenger's side door is opened from both the inside and the outside of the car, and the welcoming mode is determined to be the passenger getting off the car. When the unlocking trigger mode is triggered by the interior door lock switch, and the door lock detection result is four-door unlocking, the driver's side door is opened from the inside of the car and the passenger's side door is opened from the outside of the car at the same time, and the welcoming mode is determined to be the driver getting off the car.

[0086] Step 103: Collect ambient brightness in real time.

[0087] In the first embodiment of the present invention, after the welcoming mode is determined by the unlocking trigger mode and the door lock detection result, the lights are controlled to respond to different welcoming modes. Controlling the lights requires determining the target power and specific response content of each light. To achieve a better light response effect, the target power of the lights is positively correlated with the ambient brightness. Therefore, when determining the target power of the lights, it is necessary to collect the ambient brightness in real time, and determine the target power of the lights according to the current ambient brightness. Among them, an ambient light sensor can be used to collect the ambient brightness.

[0088] Step 104: Compare the ambient brightness with a preset brightness threshold to determine the target power.

[0089] Further, in the first embodiment of the present invention, comparing the ambient brightness with a preset brightness threshold to determine the target power includes:

[0090] The preset brightness threshold includes a first brightness threshold and a second brightness threshold, and the first brightness threshold is greater than the second brightness threshold;

[0091] When the ambient brightness is greater than the first brightness threshold, determining the target power as a preset maximum power;

[0092] When the ambient brightness is less than the second brightness threshold, determining the target power as a preset minimum power;

[0093] When the ambient brightness is less than or equal to the first brightness threshold and greater than or equal to the second brightness threshold, the target power is calculated according to the ambient brightness.

[0094] In the first embodiment of the present invention, in order to standardize the calculation method of the target power of the headlight, the maximum and minimum values ​​of the headlight power are limited, and correspondingly, the maximum and minimum values ​​of the ambient brightness are set. Therefore, when determining the target power of the headlight according to the ambient brightness, the ambient brightness is first compared with the preset brightness threshold. If the ambient brightness is greater than the preset maximum value of the ambient brightness, that is, the first brightness threshold, the target power of the headlight is determined to be the preset maximum power; if the ambient brightness is greater than the preset minimum value of the ambient brightness, that is, the second brightness threshold, the target power of the headlight is determined to be the preset minimum power; if the ambient brightness is between the first brightness threshold and the second brightness threshold, the target power of the headlight is calculated according to the functional relationship between the ambient brightness and the target power.

[0095] Further, in the first embodiment of the present invention, the target power is calculated according to the ambient brightness, specifically:

[0096] Get the preset brightness range and the preset power range;

[0097] Associating the minimum brightness in the preset brightness range with the minimum power in the preset power range to form first data;

[0098] Associating the maximum brightness in the preset brightness range with the maximum power in the preset power range to form second data;

[0099] A brightness power function is formed based on the first data and the second data, and a target power is calculated based on the brightness power function.

[0100] In the first embodiment of the present invention, when the ambient brightness is between the first brightness threshold and the second brightness threshold, the target power of the headlight can be calculated using a brightness power function. The brightness power function is used to describe the relationship between the ambient brightness and the target power of the headlight. The brightness power function uses a preset ambient brightness range and a preset power range as constraint ranges, associates the minimum brightness in the preset brightness range with the minimum power in the preset power range, and associates the maximum brightness in the preset brightness range with the maximum power in the preset power range, thereby constructing a brightness power function in which the ambient brightness is positively correlated with the target function. After the brightness power function is formed, the target power of the headlight can be calculated according to the current ambient brightness.

[0101] Further, in the first embodiment of the present invention, the target power is calculated according to the ambient brightness, specifically:

[0102] Based on the first data and the second data, a brightness power function is formed, specifically:

[0103] Establishing a rectangular coordinate system, constructing a first coordinate according to the first data, and constructing a second coordinate using the second data;

[0104] Connecting the first coordinate and the second coordinate to form a first straight line;

[0105] Deriving a linear relationship function between brightness and power according to the first straight line;

[0106] The linear relationship function is determined as a brightness power function.

[0107] In the first embodiment of the present invention, the ambient brightness and the target power of the headlight may be in a linear relationship, that is, the brightness power function is a linear function. Therefore, after obtaining the first data associated with the minimum brightness and the minimum power and the second data associated with the maximum brightness and the maximum power, a rectangular coordinate system is established, with the power as the ordinate and the ambient brightness as the abscissa. Two coordinate points are obtained on the rectangular coordinate system according to the first data and the second data, and the two coordinate points are connected with a straight line segment to obtain a linear brightness power function. Based on the brightness power function, the controller can calculate the target power of the headlight corresponding to different ambient brightnesses.

[0108] Step 105: Control the intelligent vehicle lighting system according to the welcoming mode and the target power.

[0109] Further, in the first embodiment of the present invention, the intelligent vehicle lighting system is controlled according to the welcoming mode and the target power, specifically:

[0110] When it is determined through the door lock states of each door that there is an unlocked door in an open state, each headlight is controlled to enter a corresponding welcoming mode according to the welcoming mode and the target power;

[0111] When each headlight is in the welcome mode, if it is detected that the unlocked door is in the closed state, each headlight is controlled to exit the welcome mode.

[0112] In the first embodiment of the present invention, the door lock state of the vehicle door includes whether the door lock of the vehicle door is unlocked and whether the vehicle door is opened. When there is a door that is unlocked and opened, it is determined that the intelligent vehicle light system needs to enter the welcome mode. At this time, according to the door lock state of each vehicle door, the vehicle door with the door lock state of unlocked is determined as the unlocked vehicle door, and the welcome mode is determined according to the door opening mode and unlocking trigger mode of the unlocked vehicle door, and the target power of the vehicle light is determined according to the currently collected ambient brightness. When the vehicle door is unlocked, each vehicle light in the intelligent vehicle light system is controlled to enter the corresponding welcome mode according to the welcome mode and the target power. When each vehicle light enters the welcome mode, if it is detected that the door state of the unlocked vehicle door is changed from open to closed, it is determined that the driver or passenger has completed getting on or off the vehicle, and at this time, each vehicle light in the intelligent vehicle light system is controlled to exit the welcome mode. The present invention determines whether each vehicle light in the intelligent vehicle light system enters the welcome mode according to the door lock state of the vehicle door, and controls the duration of each vehicle light entering the welcome mode.

[0113] In the first embodiment of the present invention, when controlling each headlight in the intelligent headlight system to enter the welcome mode, the power adjustment of each headlight is achieved by controlling the power supply current or the power supply voltage. Specifically, after the target power of each headlight is determined according to the ambient brightness, the power supply current or the power supply voltage of each headlight can be calculated, and the calculated power supply current or the power supply voltage is used to power each headlight, so that each headlight operates at the target power.

[0114] Further, in the first embodiment of the present invention, each headlight is controlled to enter a corresponding welcoming mode according to the welcoming mode and the target power, specifically:

[0115] Determining the display content of each headlight according to the welcoming mode and the target power;

[0116] The target power is used as the headlight power of each headlight, and each headlight is controlled to project the display content.

[0117] In the first embodiment of the present invention, the target power of the headlights not only determines the operating brightness of the headlights, but also determines the operating content of each headlight. By setting different headlight display contents, each headlight can project different display contents under different target powers, thereby flexibly adapting to different headlight powers and making the power distribution of the vehicle more balanced.

[0118] Furthermore, in the first embodiment of the present invention, the display content of each headlight is determined according to the welcoming mode and the target power, specifically:

[0119] Determine that the display content of each car taillight is the opening pattern and text for unlocking the car door;

[0120] When the welcoming mode is when the driver is getting on the vehicle or when the driver is getting off the vehicle, the display content of each headlight is determined to be the vehicle status parameter;

[0121] When the welcoming mode is passengers boarding, the display content of each headlight is determined to be passengers boarding;

[0122] When the welcoming mode is passengers getting off the bus, the display content of each headlight is determined to be passengers getting off the bus;

[0123] When the target power is the minimum power, the display content of each welcome light is determined to be a light carpet;

[0124] When the target power is not the minimum power, determining that the display content of each welcome light is a dynamic pattern;

[0125] The dynamic pattern is determined according to the welcoming method, specifically:

[0126] When the welcoming mode is when the driver gets on the bus or the passenger gets on the bus, the dynamic pattern is determined to be a dynamic welcome pattern;

[0127] When the welcoming method is that the driver gets off the vehicle or the passenger gets off the vehicle, the dynamic pattern is determined to be a dynamic farewell pattern.

[0128] In the first embodiment of the present invention, the vehicle lights in the intelligent vehicle light system include vehicle tail lights, headlights and welcome lights. The display content of each vehicle light is determined according to different welcome modes and target power combinations.

[0129] Optionally, when the welcoming method is for the driver to get on the car, each headlight projects the car status parameters at the target power, including battery power, tire pressure, indoor temperature, etc., and projects the car status parameters on the ground to remind the driver; each welcome light projects different display content according to different target powers. For example, when the target power is the minimum power, each welcome light projects a light carpet; when the target power is not the minimum power, each welcome light projects a dynamic welcome pattern; each car taillight projects the corresponding unlocking door opening pattern and text at the target power.

[0130] Optionally, when the welcoming method is for the driver to get off the car, each headlight projects the car status parameters at the target power, including battery power, tire pressure, outdoor temperature, etc., and projects the car status parameters on the ground to remind the driver; each welcome light projects different display content according to different target powers. For example, when the target power is the minimum power, each welcome light projects a light carpet; when the target power is not the minimum power, each welcome light projects a dynamic farewell pattern; each car taillight projects the corresponding unlocking door opening pattern and text at the target power.

[0131] Optionally, when the welcoming method is for passengers to get on the bus, each headlight projects the words "Passengers get on the bus" at the target power to remind surrounding traffic participants; each welcome light projects different display content according to different target powers. For example, when the target power is the minimum power, each welcome light projects a light carpet; when the target power is not the minimum power, each welcome light projects a dynamic welcome pattern; each car taillight projects the corresponding unlocking door opening pattern and text at the target power.

[0132] Optionally, when the welcoming method is for passengers to get off the car, each headlight projects the words "passengers get on the car" at the target power to remind surrounding traffic participants; each welcome light projects different display content according to different target powers. For example, when the target power is the minimum power, each welcome light projects a light carpet; when the target power is not the minimum power, each welcome light projects a dynamic farewell pattern; each car taillight projects the corresponding unlocking door opening pattern and text at the target power.

[0133] As an example of the first embodiment of the present invention, see Figure 2 , is a flow chart of another embodiment of the intelligent vehicle light system control method provided by the present invention. An unlocking request is received, and a welcoming mode is determined based on the analysis of the unlocking trigger mode. The welcoming mode includes driver boarding, driver getting off, passenger boarding, and passenger getting off. At the same time, the ambient brightness is collected, and the first brightness threshold L1 and the second brightness threshold L2 are used to divide the situation into three categories according to different ambient brightness, and the vehicle light power is determined according to different ambient brightness. After the welcoming mode and vehicle light power are obtained through analysis, the intelligent vehicle light system is controlled so that each vehicle light projects the corresponding display content with the corresponding vehicle light power.

[0134] In summary, the first embodiment of the present invention provides a method for controlling an intelligent vehicle lighting system, which receives an unlock request, obtains an unlock trigger mode and a door lock detection result; determines a welcoming mode according to the unlock trigger mode and the door lock detection result; collects ambient brightness in real time; compares ambient brightness with a preset brightness threshold to determine a target power; and controls the intelligent vehicle lighting system according to the welcoming mode and the target power.
