The lighting control method provided in the embodiment of the present application is explained in detail below.

FIG2 is a flow chart of a lighting control method provided by the present application, which can be applied to the controller in the above-mentioned vehicle, and when the controller executes the corresponding steps, it can be specifically executed by the MCU in the controller. Referring to FIG2, an embodiment of the present application provides a lighting control method, including:

Step 1001: The controller controls the vehicle light device to start and emit light in response to a light-on instruction.

Optionally, the light-on instruction may be an instruction input by a user through an operation input device to instruct the controller to supply power to the vehicle light device and control the vehicle light device to emit light.

When the controller receives the light-on instruction, the controller may confirm that it is necessary to supply power to the vehicle light device or control the vehicle light in the vehicle light device to emit light.

The input device may be a button installed on the vehicle or a touch-operated electronic screen, which is not limited in the embodiments of the present application.

Optionally, the vehicle light device may be any of the vehicle light devices mentioned above.

Starting the vehicle light device may refer to the controller supplying power to the vehicle light device, and specifically may refer to the controller outputting electrical energy to the vehicle light device according to a default current or a default voltage to supply power to the vehicle light device, so that the vehicle light in the vehicle light device emits light.

In this way, when the user inputs the light-on command, the controller can accurately and timely control the vehicle light device or the vehicle light in the vehicle light device to emit light, so as to provide the user with a light source for lighting in a timely manner, and can provide the user with effective lighting assistance.

Step 1002: If the speed of the vehicle is 0, the controller adjusts the amount of electrical energy input to the headlight device according to the parking time of the vehicle to adjust the brightness of the light emitted by the headlight device.

Optionally, the starting time of the parking time is the time when the vehicle speed was last not 0, and the ending time of the parking time is the current time.

Optionally, the amount of electric energy input to the headlight device may refer to the amount of electric energy input by the power supply unit in the controller to the headlight power supply circuit G2 in the headlight device, or it may refer to the electric energy flowing through the headlight power supply circuit G2 in the headlight device when the headlight power supply circuit G2 is turned on.

Exemplarily, the speed of the vehicle can be detected by the speed detection device S. When the speed detection device S detects the speed of the vehicle, a speed signal for the speed of the vehicle can be output to the signal processing unit X, and the signal processing unit X outputs the speed signal to the MCU so that the MCU can parse and identify the speed signal to determine the speed of the vehicle.

It is worth noting that when the headlight device emits light, the brightness of the light emitted by the headlight device is determined by the amount of electrical energy input to the headlight device. Generally, the greater or more electrical energy input to the headlight device, the greater the brightness of the light emitted by the headlight device, and vice versa, the smaller the brightness of the light emitted by the headlight device.

It is worth noting that if the vehicle speed is 0, it can be considered that the vehicle is in a stationary or parked state, and the longer the vehicle speed is 0, that is, the longer the parking time, the longer the vehicle is in a stationary or parked state. In order to save electric energy, the longer the parking time, the smaller the electric energy input to the headlight device can be adjusted, and the lower the brightness of the light emitted by the headlight device. In this way, the brightness of the light emitted by the headlight device can be reduced in the case of long-term parking, reducing the electric energy consumed by the headlight device when the vehicle is in a stationary or parked state.

Step 1003: If the vehicle speed is not zero, the controller adjusts the amount of electrical energy input to the vehicle light device according to the vehicle speed to adjust the brightness of the light emitted by the vehicle light device.

It is worth noting that if the vehicle speed is not 0, it can be considered that the vehicle is in a moving state, and the greater the speed of the vehicle, the faster the vehicle moves. In the case of faster movement, the braking distance of the vehicle will become longer, so the user needs to observe a farther field of view. In a dim environment, the vehicle is required to provide lighting for the user. Therefore, the greater the amount of electrical energy input to the headlight device, the greater the brightness of the light emitted by the headlight device. In the case of a lower speed, the smaller the amount of electrical energy input to the headlight device, the smaller the brightness of the light emitted by the headlight device. In this way, the flexibility of the light emitted by the headlight device can be improved.

It is worth noting that when the vehicle speed is low, the braking distance of the vehicle is short, so the user can stop the vehicle within a short distance. In this case, a smaller range or lower brightness lighting can be provided to the user, so the brightness of the light emitted by the headlight device can be reduced, and the power consumed by the headlight device when the vehicle is at a lower speed can be reduced. When the vehicle is at a higher speed, the user needs to stop the vehicle at a longer distance due to the longer braking distance of the vehicle. In this case, a larger range or higher brightness lighting can be provided to the user, so that when the vehicle is at a higher speed, the user can be provided with light that can illuminate a larger range or a longer distance, thereby ensuring the safety of the user. In this way, the effect of providing the user with effective lighting assistance and saving power can be achieved.

In an embodiment of the present application, the controller responds to a light-on command to control the headlight device on the vehicle to start and emit light. If the vehicle speed is 0, the controller adjusts the amount of electric energy input to the headlight device according to the parking time of the vehicle to adjust the brightness of the light emitted by the headlight device; if the vehicle speed is not 0, the controller adjusts the amount of electric energy input to the headlight device according to the vehicle speed to adjust the brightness of the light emitted by the headlight device.

When the headlight device emits light, the greater or more electric energy is input to the headlight device, the greater the brightness of the light emitted by the headlight device, and vice versa, the smaller the brightness of the light emitted by the headlight device. Therefore, when the vehicle speed is 0, the amount of electric energy input to the headlight device is adjusted according to the parking time of the vehicle to adjust the brightness of the light emitted by the headlight device. Specifically, the greater the parking time, the smaller the amount of electric energy input to the headlight device. In this way, the brightness of the light emitted by the headlight device can be reduced in the case of long-term parking, and the electric energy consumed by the headlight device when the vehicle is in a stationary or parking state can be reduced.

In a possible implementation, referring to FIG. 3 , the controller adjusts the amount of electric energy input to the vehicle lamp device according to the parking time of the vehicle, including:

Step 1004: Determine a target electric energy signal corresponding to the parking duration according to a pre-established parking duration linear model and the parking duration.

Optionally, the parking duration linear model may be a linear model established by relevant technical personnel according to actual needs.

The parking time linear model may be used to indicate a target electric energy signal corresponding to the parking time. That is, the target electric energy signal corresponding to the parking time may be determined by the parking time linear model.

Optionally, the target power signal can be used to indicate the amount of power that the controller needs to output to the vehicle lamp device, or the amount of power that the vehicle lamp device needs to output to the vehicle lamp device. The target power signal can be a signal including a duty cycle of a pulse control signal or a target power size.

The controller can output the pulse control signal to the switch control circuit in the headlight device to control the on or off of the switch control circuit, thereby controlling the on or off of the headlight power supply circuit in the headlight device, and the magnitude of the current flowing through the headlight power supply circuit when it is on.

The duty cycle can be used to indicate the proportion of the power-on time of the pulse control signal within a complete pulse cycle or pulse period. That is to say, pulse control signals with different duty cycles can control the controller to output different amounts of electrical energy to the headlight device, and then pulse control signals with different duty cycles can be used to control the switch control circuit and/or the headlight power supply circuit differently.

Exemplarily, the parking time linear model may include: a parking time and a pulse control signal duty cycle linear model, or a parking time and electric energy size linear model.

The parking duration and pulse control signal duty cycle linear model can be used to indicate the duty cycle of the pulse control signal corresponding to the parking duration. The parking duration and electric energy size linear model can be used to indicate the electric energy size corresponding to the parking duration.

In this way, the target electric energy signal corresponding to the parking time can be accurately determined to accurately control the electric energy input into the vehicle lamp device by the controller.

Step 1005: According to the target power signal, input power of the target power level into the vehicle light device.

Optionally, the target electric energy magnitude may be used to indicate a current value, a voltage value, a power value and/or any other possible physical parameter of the electric energy input into the vehicle lamp device, which is not limited in the embodiment of the present application.

Since the brightness of the light emitted by the headlight device is determined by the amount of electric energy input into the headlight device, after the target amount of electric energy is input into the headlight device, the headlight device will emit electric energy matching the target amount of electric energy.

In this way, the purpose of adjusting the brightness of the light emitted by the vehicle lamp device according to the parking time can be achieved.

Since the parking time linear model may include: a parking time and a pulse control signal duty cycle linear model. In a possible implementation, referring to FIG. 4 , according to a pre-established parking time linear model and the parking time, determining a target electric energy signal corresponding to the parking time includes:

Step 1006: According to the parking time, a value of the duty cycle of the pulse control signal corresponding to the parking time is obtained from a linear model of the parking time and the duty cycle of the pulse control signal.

Exemplarily, the linear model of parking duration and pulse control signal duty cycle may include multiple duty cycles with different values, and the duty cycles with different values may respectively correspond to a parking duration. In this case, as long as the parking duration changes, the determined duty cycle value will definitely change. Then, when the pulse control signal is output to the headlight device, it can be ensured that the electrical energy input by the controller to the headlight device also changes continuously.

For example, when the parking time is 1 second, the corresponding duty cycle value is 60%, when the parking time is 2 seconds, the corresponding duty cycle value is 59.9%, ... when the parking time is 500 seconds, the corresponding duty cycle value is 10%, ... when the parking time is 600 seconds, the corresponding duty cycle value is 10%. The corresponding duty cycle value is 0%.

Different duty ratios may also correspond to a parking time interval, which may be an interval set by relevant technicians. In this case, when the parking time is in the same parking time interval, the duty ratio is constant, that is, the target electric energy input to the vehicle lamp device is constant, and the brightness of the light emitted by the vehicle lamp device is constant within the parking time interval.

For another example, four parking time intervals can be set in the parking time and pulse control signal duty cycle linear model, the first parking time interval is 0-3 minutes, the second parking time interval is 3-30 minutes, the third parking time interval is 30-60 minutes, and the fourth parking time interval is greater than 60 minutes. The duty cycle value corresponding to the first parking time interval is the duty cycle value of the pulse control signal currently output by the controller to the vehicle light device or 50%, the duty cycle value corresponding to the second parking time interval is 40%, the duty cycle value corresponding to the third parking time interval is 30%, and the duty cycle value corresponding to the fourth parking time interval is 20%. More parking time intervals can also be set, and the duty cycle values corresponding to each parking time interval can be adjusted according to actual needs.

In this way, the value of the duty cycle of the pulse control signal corresponding to the parking time can be accurately obtained in the linear model of the parking time and the duty cycle of the pulse control signal.

Inputting electric energy of a target electric energy amount into the vehicle lamp device according to the target electric energy signal comprises:

Step 1007: Input a target pulse control signal having the duty cycle to a control circuit of the vehicle light device to trigger the control circuit to input electric energy of a target electric energy amount to the vehicle light device.

Optionally, the target pulse control signal may refer to a pulse control signal having the value of the duty cycle determined above.

Optionally, referring to (a) in FIG. 1 , the control circuit of the vehicle lamp device C may include a switch control circuit Z, a vehicle lamp power supply circuit G2 and/or an overcurrent protection circuit B.

Inputting the target pulse control signal having the value of the duty cycle into the control circuit of the headlight device can specifically be inputting the target pulse control signal into the switch control circuit Z to turn on the switch control circuit Z and the headlight power supply circuit G2 to control the current flowing through the headlight power supply circuit G2 to match the target electric energy.

While inputting the target pulse control signal to the switch control circuit Z, the power supply unit G1 can also output electric energy to the headlight power supply circuit G2 in the headlight device to ensure that the headlight power supply circuit G2 can output electric energy to the headlight in the headlight device so that the headlight can emit light.

The control circuit is triggered to input electric energy of the target amount to the headlight device. Specifically, the switch control circuit Z can control the headlight power supply circuit G2 to be turned on, and control the amount of current flowing through the headlight power supply circuit G2, so that the electric energy input by the controller to the headlight device can flow into the headlight power supply circuit G2, and the headlight power supply circuit G2 can output electric energy of the target amount to the headlight in the headlight device.

It is worth noting that step 1006 and step 1007 are applicable to the vehicle provided in (a) of Figure 1. In this way, it can be ensured that the controller can accurately input electric energy of the target electric energy size to the vehicle lamp device, thereby ensuring that the lamp in the vehicle lamp device can emit light matching the electric energy of the target electric energy size.

In addition, when a target pulse control signal having a value of the duty ratio is input to the control circuit of the vehicle lamp device, The target electric energy input to the headlight device is different, and the brightness of the light emitted by the headlight in the headlight device is also different. For example, when the duty cycle is 40%, the brightness of the light emitted by the headlight in the headlight device is 40% of the maximum brightness, and when the duty cycle is 30%, the brightness of the light emitted by the headlight in the headlight device is 30% of the maximum brightness. This embodiment of the application does not limit this.

Since the parking time linear model may include: a parking time and electric energy linear model, in a possible implementation, referring to FIG. 5 , according to the pre-established parking time linear model and the parking time, determining the target electric energy signal corresponding to the parking time includes:

Step 1008: According to the parking time, a target electric energy level corresponding to the parking time is obtained from a linear model of the parking time and the electric energy level.

Exemplarily, the linear model of parking duration and electric energy size may include multiple different electric energy sizes, and each electric energy size may correspond to a parking duration. In this case, as long as the parking duration changes, the determined target electric energy size will definitely change. Then, when the electric energy of the target electric energy size is output to the headlight device, it can be ensured that the electric energy input by the controller to the headlight device is continuously changing.

For example, when the parking time is 1 second, the corresponding current is 5A of electric energy, when the parking time is 2 seconds, the corresponding current is 4.99A of electric energy,..., when the parking time is 300 seconds, the corresponding current is 2A of electric energy,..., when the parking time is 500 seconds, the corresponding current is 0A of electric energy.

Each electric energy level may also correspond to a parking time interval. In this case, when the parking time is in the same parking time interval, the target electric energy level is constant, that is, the electric energy input to the vehicle lamp device of the target electric energy level is constant, and then within this parking time interval, the brightness of the light emitted by the vehicle lamp device is constant.

For another example, four parking time intervals can be set in the parking time and pulse control signal duty cycle linear model, the first parking time interval is 0-3 minutes, the second parking time interval is 3-30 minutes, the third parking time interval is 30-60 minutes, and the first parking time interval is an interval greater than 60 minutes. The first parking time interval corresponds to an electric energy with a current of 5A, the second parking time interval corresponds to an electric energy with a current of 4A, the third parking time interval corresponds to an electric energy with a current of 3A, and the fourth parking time interval corresponds to an electric energy with a current of 2A.

In this way, the target electric energy amount corresponding to the parking time can be accurately obtained in the linear model of parking time and electric energy amount.

Inputting electric energy of the target electric energy amount into the vehicle lamp device comprises:

Step 1009: Inputting electric energy having the target electric energy level into the control circuit of the vehicle lamp device to trigger the control circuit to input electric energy having the target electric energy level into the vehicle lamp device.

Optionally, referring to (b) in FIG. 1 , the control circuit of the vehicle lamp device C may include a vehicle lamp power supply circuit G2 .

Inputting electric energy having the target electric energy magnitude into the control circuit of the vehicle lamp device may specifically be inputting electric energy having the target electric energy magnitude into the vehicle lamp power supply circuit G2 .

When electric energy with the target electric energy level is input to the control circuit of the vehicle lamp device, the vehicle lamp power supply circuit G2 can be turned on, and the vehicle lamp power supply circuit G2 can fully input the electric energy with the target electric energy level into the vehicle lamp in the vehicle lamp device.

The control circuit is triggered to input electric energy of the target amount to the headlight device, specifically, the electric energy input by the controller to the headlight device can flow into the headlight power supply circuit G2, and the headlight power supply circuit G2 outputs electric energy of the target amount to the headlight in the headlight device.

It is worth noting that step 1008 and step 1009 are applicable to the vehicle provided in (b) of Figure 1. In this way, it can be ensured that the controller can accurately input electric energy of the target electric energy size to the vehicle lamp device, thereby ensuring that the vehicle lamp in the vehicle lamp device can emit light matching the electric energy of the target electric energy size.

In addition, if different electric energies having the target electric energy magnitude are input to the control circuit of the vehicle lamp device, the brightness of the light emitted by the vehicle lamp in the vehicle lamp device is also different. For example, when the input current is 3A of electric energy, the brightness of the light emitted by the vehicle lamp in the vehicle lamp device is 40% of the maximum brightness, and when the input current is 2A of electric energy, the brightness of the light emitted by the vehicle lamp in the vehicle lamp device is 30% of the maximum brightness. This embodiment of the present application does not limit this.

In a possible implementation, referring to FIG. 6 , the controller adjusts the amount of electric energy input to the vehicle light device according to the vehicle speed, including:

Step 1010: Determine a target electric energy signal corresponding to the vehicle speed based on a pre-established vehicle speed linear model and the vehicle speed.

Optionally, the vehicle speed linear model may be a linear model established by relevant technical personnel according to actual needs.

The vehicle speed linear model may be used to indicate a target electric energy signal corresponding to the vehicle speed, that is, the target electric energy signal corresponding to the vehicle speed may be determined by the vehicle speed linear model.

Exemplarily, the vehicle speed linear model may include: a vehicle speed and pulse control signal duty cycle linear model, or a vehicle speed and electric energy size linear model.

The vehicle speed and pulse control signal duty cycle linear model can be used to indicate the duty cycle value of the pulse control signal corresponding to the vehicle speed. The vehicle speed and electric energy linear model can be used to indicate the electric energy required to be input to the vehicle light device corresponding to the vehicle speed.

In this way, the target electric energy signal corresponding to the vehicle speed can be accurately determined to accurately control the electric energy input into the vehicle light device by the controller.

Step 1011: According to the target power signal, input power of a target power level into the vehicle light device.

In this way, the purpose of adjusting the brightness of the light emitted by the vehicle lamp device according to the vehicle speed can be achieved.

Since the parking time linear model may include: a linear model of vehicle speed and pulse control signal duty cycle, in a possible implementation, referring to FIG. 7 , according to a pre-established vehicle speed linear model and the vehicle speed, determining a target electric energy signal corresponding to the vehicle speed includes:

Step 1012: According to the vehicle speed, a value of the duty cycle of the pulse control signal corresponding to the vehicle speed is obtained from a linear model of the vehicle speed and the duty cycle of the pulse control signal.

Exemplarily, the vehicle speed and pulse control signal duty cycle linear model may include a plurality of duty cycles with different values, and different The duty cycle value can correspond to a vehicle speed respectively. In this case, as long as the vehicle speed changes, the determined duty cycle value will definitely change. Then, when the pulse control signal is output to the headlight device, it can be ensured that the electrical energy input by the controller to the headlight device also changes continuously.

For example, assuming that the maximum speed of the vehicle is 35 kilometers per hour (km/h), the corresponding duty cycle value when the vehicle speed is 3km/h is 10%, the corresponding duty cycle value when the vehicle speed is 6km/h is 20%,... and the corresponding duty cycle value when the vehicle speed is 35km/h is 100%.

The duty cycle of different values may also correspond to a vehicle speed range, which may be a range set by relevant technicians. In this case, when the vehicle speed is in the same speed range, the determined duty cycle is unchanged, that is, the target electric energy input to the vehicle lamp device is unchanged, and then within this vehicle speed range, the brightness of the light emitted by the vehicle lamp device is unchanged.

For another example, assuming that the maximum speed of the vehicle is 35km/h, five speed intervals can be set in the linear model of the speed and pulse control signal duty cycle, the first speed interval is 0-15km/h, the second speed interval is 16-20km/h, the third speed interval is 21-25km/h, the fourth speed interval is 26-30km/h, and the fifth speed interval is 31-35km/h. The duty cycle value corresponding to the first speed interval is 50%, the duty cycle value corresponding to the second speed interval is 60%, the duty cycle value corresponding to the third speed interval is 70%, the duty cycle value corresponding to the fourth speed interval is 85%, and the duty cycle value corresponding to the fourth speed interval is 100%. More speed intervals can also be set, and the duty cycle values corresponding to each speed interval can be adjusted according to actual needs.

In this way, the value of the duty cycle of the pulse control signal corresponding to the vehicle speed can be accurately obtained in the linear model of the vehicle speed and the duty cycle of the pulse control signal.

Step 1013: Input a target pulse control signal having the duty cycle to a control circuit of the vehicle light device to trigger the control circuit to input electric energy of a target electric energy amount to the vehicle light device.

It is worth noting that step 1012 and step 1013 are applicable to the vehicle provided in (a) of FIG. 1 , and the input of the target pulse control signal having the above-determined duty cycle value to the control circuit of the vehicle lamp device can refer to the specific description in the above-mentioned embodiment, which will not be repeated here. In this way, it can be ensured that the controller can accurately input the target electric energy size to the vehicle lamp device, thereby ensuring that the vehicle lamp in the vehicle lamp device can emit light matching the target electric energy size.

In addition, since the target pulse control signal with the determined duty cycle value is input to the control circuit of the vehicle lamp device, the target electric energy input to the vehicle lamp device is also different, and the brightness of the light emitted by the vehicle lamp in the vehicle lamp device is also different. For example, when the duty cycle value is 100%, the brightness of the light emitted by the vehicle lamp in the vehicle lamp device is 100% of the maximum brightness, and when the duty cycle value is 85%, the brightness of the light emitted by the vehicle lamp in the vehicle lamp device is 85% of the maximum brightness. This embodiment of the present application does not limit this.

In a possible implementation, referring to FIG8 , the vehicle speed linear model includes: a vehicle speed and electric energy linear model.

According to a pre-established vehicle speed linear model and the vehicle speed, a target electric energy signal corresponding to the vehicle speed is determined, including:

Step 1014: According to the vehicle speed, a target electric energy amount corresponding to the parking time is obtained from a linear model of the vehicle speed and electric energy amount.

Exemplarily, the linear model of vehicle speed and electric energy size may include multiple different electric energy sizes, and each electric energy size may correspond to a vehicle speed. In this case, as long as the vehicle speed changes, the determined target electric energy size will definitely change. Then, when the electric energy of the target electric energy size is output to the headlight device, it can be ensured that the electric energy input by the controller to the headlight device is continuously changing.

For example, assuming that the maximum speed of the vehicle is 30 kilometers per hour (km/h), when the vehicle speed is 3km/h, the corresponding current is 0.5A of electric energy, when the vehicle speed is 6km/h, the corresponding current is 1A of electric energy, and... when the vehicle speed is 30km/h, the corresponding current is 5A of electric energy.

Each electric energy level may also correspond to a vehicle speed range. In this case, when the vehicle speed is in the same vehicle speed range, the target electric energy level is constant, that is, the electric energy input to the vehicle lamp device of the target electric energy level is constant, and then within this vehicle speed range, the brightness of the light emitted by the vehicle lamp device is constant.

For another example, five speed intervals can be set in the linear model of the speed and pulse control signal duty cycle, the first speed interval is 0-15km/h, the second speed interval is 16-20km/h, the third speed interval is 21-25km/h, the fourth speed interval is 26-30km/h, and the fifth speed interval is 31-35km/h. The first speed interval corresponds to an electric energy with a current of 1A, the second speed interval corresponds to an electric energy with a current of 2A, the third speed interval corresponds to an electric energy with a current of 3A, the fourth speed interval corresponds to an electric energy with a current of 4A, and the fifth speed interval corresponds to an electric energy with a current of 5A.

In this way, the target electric energy size corresponding to the vehicle speed can be accurately obtained in the linear model of vehicle speed and electric energy size.

Inputting an electric energy signal of the target electric energy amount into the vehicle lamp device comprises:

Step 1015: Inputting electric energy having the target electric energy level into the control circuit of the vehicle light device to trigger the control circuit to input electric energy having the target electric energy level into the vehicle light device.

It is worth noting that step 1014 and step 1015 are applicable to the vehicle provided in (b) of FIG. 1 . The input of electric energy having the target electric energy size to the control circuit of the vehicle lamp device can refer to the specific description in the above embodiment, which will not be repeated here. In this way, it can be ensured that the controller can accurately input electric energy of the target electric energy size to the vehicle lamp device, thereby ensuring that the vehicle lamp in the vehicle lamp device can emit light matching the electric energy of the target electric energy size.

In addition, if different electric energies having the target electric energy magnitude are input to the control circuit of the vehicle lamp device, the brightness of the light emitted by the vehicle lamp in the vehicle lamp device is also different. For example, when the input current is 1A of electric energy, the brightness of the light emitted by the vehicle lamp in the vehicle lamp device is 20% of the maximum brightness, and when the input current is 5A of electric energy, the brightness of the light emitted by the vehicle lamp in the vehicle lamp device is 100% of the maximum brightness. This embodiment of the present application does not limit this.

In a possible implementation, referring to FIG9 , since the vehicle further includes: an acceleration detection device. The controller adjusts the amount of electrical energy input to the vehicle light device according to the vehicle speed, including:

Step 1016: Receive and analyze the acceleration signal output by the acceleration detection device to obtain the acceleration of the vehicle indicated by the acceleration signal.

Optionally, the signal processing unit X may receive the acceleration signal and output the acceleration signal to the MCU. The MCU analyzes the acceleration signal.

Step 1017: Determine whether the direction of the acceleration is opposite to or the same as the direction of the vehicle speed.

Step 1018: If they are the same, adjust the amount of electrical energy input to the vehicle lighting device according to the vehicle speed.

Generally, if the direction of the acceleration is the same as the direction of the vehicle speed, it indicates that the vehicle is accelerating, and if the value of the acceleration is greater than the preset threshold, it indicates that the vehicle is in a state of rapid acceleration, and the amount of electrical energy input to the headlight device needs to be adjusted according to the vehicle speed.

Step 1019: If not, determine whether the acceleration value is greater than a preset threshold.

Optionally, the preset threshold may be a threshold set in advance by relevant technical personnel. The preset threshold may be an absolute value of acceleration. Generally, the preset threshold may be set larger, and the present application does not limit this.

Generally, if the direction of the acceleration is opposite to the direction of the vehicle speed, it indicates that the vehicle is decelerating, and if the value of the acceleration is greater than the preset threshold, it indicates that the vehicle is in a state of rapid deceleration. If the vehicle is in a state of rapid deceleration, it indicates that the user may have encountered a more urgent situation, and at this time, a higher brightness light is needed to illuminate the surrounding environment, so the amount of power input to the vehicle light device may not be adjusted.

Step 1020: If the acceleration value is greater than the preset threshold, then the amount of electrical energy input to the vehicle light device is not adjusted.

It is worth noting that when the acceleration value is greater than the preset threshold, it can be determined that the vehicle is in a state of rapid acceleration or rapid deceleration. Then, it is necessary to determine whether the direction of the acceleration is opposite to or the same as the direction of the vehicle speed.

Step 1021: If the acceleration value is not greater than the preset threshold, the amount of electrical energy input to the vehicle light device is adjusted according to the vehicle speed.

It is worth noting that when the acceleration value is not greater than the preset threshold, it can be determined that the vehicle is not in a state of rapid acceleration or deceleration. Then, the amount of electrical energy input to the headlight device can be adjusted according to the vehicle speed, thereby adjusting the brightness of the light emitted by the headlight device.

In a possible implementation, after executing step 1016, the amount of electric energy input to the vehicle light device may be adjusted by executing the following steps:

Determine whether the value of the acceleration is greater than a preset threshold.

If not, the amount of electrical energy input to the vehicle light device is adjusted according to the vehicle speed.

If so, it is determined whether the direction of the acceleration is opposite to or the same as the direction of the vehicle speed.

If they are the same, the amount of electrical energy input to the vehicle light device is adjusted according to the vehicle speed.

If the opposite is true, the amount of electrical energy input to the vehicle lamp device will not be adjusted.

In this way, by adjusting the amount of electrical energy input to the vehicle lamp device in a variety of different ways to adjust the brightness of the light emitted by the vehicle lamp device, the flexibility of light control can be improved. In addition, by adjusting the brightness of the light emitted by the vehicle lamp device according to the direction of the acceleration and the speed of the vehicle, as well as the magnitude of the acceleration, more effective lighting assistance can be provided to the user according to actual conditions.

In one possible manner, after executing the step of determining whether the direction of the acceleration is opposite to or the same as the direction of the vehicle speed, if the direction is opposite, the magnitude of the electric energy input to the vehicle light device may be adjusted to a preset magnitude of electric energy, which may be set in advance by relevant technicians. After the preset magnitude of electric energy is input to the vehicle light device, the vehicle light device may emit a signal matching the preset magnitude of electric energy. Light.

Generally, the brightness of the light that matches the preset electric energy level may be greater than 50% of the maximum brightness of the vehicle light device, which is not limited in the embodiment of the present application.

In a possible implementation, the controller controls the vehicle light device on the vehicle to start and emit light in response to the light-on instruction, including:

The controller generates a preset pulse control signal in response to a light-on instruction, and outputs the preset pulse control signal to a control circuit of the vehicle light device, so that the control circuit inputs electric energy of a preset electric energy amount to the vehicle light device.

Optionally, the preset pulse control signal is a pulse control signal with a preset duty cycle, which is used to indicate a preset amount of electric energy. The preset duty cycle is also used to indicate the degree of conduction of a headlight power supply circuit in the headlight device, and the amount of current that can flow through the headlight power supply circuit when it is turned on.

The preset pulse control signal is specifically used to control the conduction of the headlight power supply circuit in the headlight device and output electric energy of a preset electric energy amount to the headlight in the headlight device.

In a possible implementation, before the controller controls the vehicle light device on the vehicle to start and emit light in response to the light-on instruction, the method further includes:

The controller receives the status information output by the status information detection device.

Optionally, the status information detection device may be any device installed on the vehicle for detecting status information, which is not limited in this embodiment of the present application.

Optionally, the status information may include information such as the voltage and current output by the battery of the vehicle, the remaining power of the battery, the temperature of the battery, the temperature of the motor, the speed of the motor, etc.

The controller determines whether the vehicle is powered on and working normally according to the status information.

If not, the controller outputs a prompt message.

Optionally, the prompt information may be in various forms of information such as light, sound, text, image, etc. The prompt information is used to indicate that the vehicle cannot be powered on and work normally, so as to promptly inform the user to troubleshoot or repair the vehicle.

If so, the controller executes the step of obtaining the vehicle speed.

In this way, the purpose of automatically adjusting the brightness of the lights can be achieved according to the real-time status of the vehicle.
