[0019] Figure 1 A flow chart of a vehicle lighting control method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the vehicle lighting control method may include:

[0020] S101: It is detected that the vehicle is in a running state.

[0021] The execution subject in the embodiments of the present disclosure may be a body control module (BCM) in any of the following embodiments.

[0022] The BCM can determine whether the vehicle is in the starting and powering state to detect whether the vehicle is in the running state. When the vehicle is in the starting and powering state, it is detected that the vehicle is in the running state; when the vehicle is not started and powered on, it is detected that the vehicle is in the non-running state or not in the running state.

[0023] BCM can be connected to the Engine Control Module (ECM) and the Vehicle Control Unit (VCU) to determine whether the vehicle is in the starting and power-on state through the ECM or VCU.

[0024] In one example, the BCM can detect whether the vehicle is in a running state by receiving the engine running state sent by the ECM through the CAN bus. The ECM is used in traditional fuel vehicles to send an engine running state signal so that the BCM can determine whether the vehicle is in a normal running state. The engine running state may include: the engine is running or the engine is not running. When the engine is running, it is determined that the vehicle is in a normal running state; when the engine is not running, it is determined that the vehicle is in a non-running state or not in a running state.

[0025] In one example, the BCM can detect whether the vehicle is in operation by receiving the vehicle high voltage status sent by the VCU via the CAN bus. The VCU is used for hybrid or pure electric vehicles to send a vehicle high voltage power-on signal so that the BCM can determine whether the vehicle is in normal operation. When the vehicle is powered on at high voltage, it is determined that the vehicle is in normal operation; when the vehicle is not powered on at high voltage, it is determined that the vehicle is in a non-operating state or not in operation. High voltage power-on refers to whether the voltage when the vehicle is powered on exceeds the set voltage value. If the voltage when the vehicle is powered on exceeds the set voltage value, it is determined that the high voltage is powered on. The set voltage value can be determined based on an empirical value, which is not limited or elaborated in this embodiment.

[0026] After the vehicle starts to be powered on, the engine of a traditional fuel vehicle starts running, and the ECM sends the engine running status signal to CAN. Or the VCU of a hybrid and new energy vehicle is powered on with high voltage, and the VCU sends the vehicle high voltage power-on and normal operation status to CAN. The BMS receives the ECM or VCU running status information through the CAN signal to determine whether the vehicle is in a normal starting and running state.

[0027] S102: Controlling turning on or off of the fog lamp according to the acquired information, where the acquired information includes environmental information of the vehicle.

[0028] BCM can identify environmental conditions and determine whether to turn on or off the fog lights based on the vehicle's environmental information, thereby preventing users from forgetting to turn on the fog lights and causing unnecessary losses. It can also avoid real-life application scenarios where users forget or do not know how to use the fog lights, improve the use of fog lights in specific environments, and automatically turn off fog lights to reduce the abuse of fog lights, thereby improving the user's smart experience during vehicle use.

[0029] The vehicle's environment information may include: weather conditions, which may include: bad weather conditions, such as rainy and foggy weather, heavy rainy weather, or rainy and snowy weather. The weather conditions may also include: visibility of the weather environment, such as low visibility conditions at night, heavy rain, or rainy and foggy weather.

[0030] As the main control unit of vehicle lights, BCM can be connected to the controlled lights through hard wires. The lights can include headlights and fog lights. BCM is responsible for judging the light control logic and controlling the opening and closing of headlights and fog lights. Among them, BCM can control the opening and closing of headlights and fog lights through built-in drive logic or common drive circuits.

[0031] The vehicle lighting control method provided by the embodiment of the present disclosure can determine whether to turn on or off the fog lights according to the environmental information of the vehicle, thereby avoiding unnecessary losses caused by users forgetting to turn on the fog lights and improving the user's intelligent experience during vehicle use.

[0032] In an exemplary embodiment of the present disclosure, before controlling the turning on or off of the fog lamp according to the acquired information, the method may further include:

[0033] The running speed of the vehicle is obtained, and the urgency of the current working condition of the vehicle is determined according to the running speed. The obtained information may also include: the urgency of the current working condition of the vehicle.

[0034] The information obtained may also include: the vehicle's driving environment, such as the urgency of the vehicle's current working condition. The BCM can determine whether to turn on or off the fog lights based on the vehicle's environmental information and the urgency of the vehicle's current working condition. It can automatically identify bad weather and turn on or off the fog lights based on driving needs of actual road conditions, thereby preventing users from forgetting to turn on the fog lights and causing unnecessary losses. It can also turn on or off the fog lights based on the urgency of the vehicle's current working condition, thereby increasing driving safety.

[0035] In one example, the BCM may determine whether to turn the fog lights on or off based on the vehicle's environmental information, and the BCM may determine how to turn the fog lights on or off based on the urgency of the vehicle's current operating conditions. The methods of turning the fog lights on or off may include: the BCM directly controls the fog lights to be on or off, or the BCM interacts with the user and then controls the fog lights to be on or off according to the user's operation.

[0036] BCM can be connected to the Electronic Stability Control (ESC) via the CAN bus, and BCM exchanges data with ESC via CAN communication. BCM determines the urgency of the vehicle's current operating conditions through the vehicle speed signal sent by ESC. ESC is used to send a vehicle speed signal so that BCM can determine how to turn on or off the fog lights based on the vehicle's running speed.

[0037] In an exemplary embodiment of the present disclosure, judging the urgency of the current working condition of the vehicle according to the running speed may include:

[0038] The running speed is compared with the first preset speed; when the running speed is greater than or equal to the first preset speed, the current operating condition of the vehicle is determined to be a first emergency state; when the running speed is less than the first preset speed, the current operating condition of the vehicle is determined to be a second emergency state, and the urgency of the second emergency state is lower than the urgency of the first emergency state.

[0039] Controlling the turning on or off of the fog lights based on the acquired information may include:

[0040] When the current working condition is the first emergency state, the fog lamp is directly controlled to be turned on or off according to the environmental information of the vehicle;

[0041] When the current working condition is the second emergency state, after determining that the fog lights need to be turned on or off based on the environmental information of the vehicle, a prompt message to turn the fog lights on or off is sent to the user, and the fog lights are controlled to be in the on or off state after detecting the user's confirmation operation.

[0042] BCM determines the urgency of the current working conditions through the vehicle speed signal of ESC, and directly turns on or off the fog lights in emergency situations. In non-emergency situations, it interacts with the user to confirm whether to turn on or off the fog lights. After the user confirms, the BCM performs the operation of turning on or off the fog lights. The vehicle's driving environment is determined by the vehicle's operating conditions and speed information, and the BCM intelligently turns on and off the fog lights to prevent users from forgetting or not knowing how to operate the fog lights, thereby improving the user's intelligent experience during vehicle use and improving the interaction between the vehicle and the user. In non-emergency situations, the human-computer interaction system accurately pushes the fog lights on or off requirements to the user, and the user decides to turn the fog lights on or off based on the actual situation, thereby avoiding users from turning on the fog lights by mistake, and avoiding the real-life application scenarios where users forget or do not know how to use the fog lights, and improving the use of fog lights in specific environments.

[0043] The current operating condition being the first emergency state may be referred to as an emergency situation, and the current operating condition being the second emergency state may be referred to as a non-emergency situation. The situation where the vehicle's running speed is greater than or equal to the first preset speed may be referred to as the vehicle's high-speed running, and the situation where the vehicle's running speed is less than the first preset speed may be referred to as the vehicle's low-speed running. The value of the first preset speed may be determined based on an empirical value, information on the road where the vehicle is located, or weather conditions, and this embodiment will not be limited or elaborated on herein.

[0044] In an exemplary embodiment of the present disclosure, the method may further include:

[0045] By detecting the user operation on the human-computer interaction interface of the entertainment system head unit (HU), it is determined whether the user's confirmation operation is detected.

[0046] BCM can be connected to HU via CAN bus, and BCM exchanges data with HU via CAN communication. BCM judges the urgency of the current working condition through the vehicle speed signal of ESC, directly turns on or off the fog lights in an emergency, and then reminds the user to drive safely through the HU host. In non-emergency situations, HU confirms with the user whether to turn on or off the fog lights, and then executes the operation of turning on or off the fog lights through BCM after the user confirms on the human-machine interface of HU.

[0047] BCM determines whether there is a need to turn on or off the fog lights based on the vehicle's environmental information. When it detects that the vehicle is driving at a low speed, BCM sends the need to turn on or off the fog lights to HU. HU interacts with the user by receiving BCM instructions and asks the user whether to turn on or off the fog lights. After the user's operation, HU can feedback the user's execution operation to BCM to turn on or off the fog lights. The user's intelligent experience is enhanced through HU intelligent interactive reminders and confirmations.

[0048] A touch area may be provided on the human-machine interface of the HU, and the touch area is used to display the turning on or off of the fog lamp to the user to inquire the user. The user may click or double-click on the touch area to confirm turning on or off the fog lamp. When the HU detects the user's single click or double click on the touch area, it determines that the user's confirmation operation is detected.

[0049] In one example, the user may be prompted to drive safely through the HU when the vehicle is traveling at high speed.

[0050] In an exemplary embodiment of the present disclosure, the method may further include:

[0051] The human-computer interaction interface of the HU is used to remind the user of the vehicle's environment, which includes rainy and foggy weather.

[0052] BCM sends the environmental information described by the detected vehicle to HU, which reminds the user of weather conditions such as rainy and foggy weather, driving at night, etc., and can remind the user to drive safely. It can also remind the user when the vehicle is driving at low speed. When the user needs to decide whether to turn on or off the fog lights when driving at low speed, the user can be informed of the current environment of the vehicle in time to remind the user of the need to turn on or off the fog lights when driving at low speed.

[0053] In an exemplary embodiment of the present disclosure, the method may further include:

[0054] Sending a prompt message to an instrument cluster (IC) to prompt a user, the prompt message may include: displaying the on or off state of the fog lamp.

[0055] BCM can be connected to IC via CAN bus, and BCM exchanges data with IC via CAN communication. BCM sends the on or off status of fog lights to IC and displays it through IC. IC receives the signal of fog lights on or off sent by BCM and displays it in the instrument in real time to remind the user of the current fog lights status, so that the user can know the usage of fog lights in time and improve the interaction between vehicle and user.

[0056] In one example, the BCM can determine whether there is a need to turn on or off the fog lights based on the information obtained, and send the need to the HU when driving at low speed. The HU interacts with the user and feeds back the execution instruction to the BCM to turn on or off the fog lights, and displays the status of the fog lights on the IC. When driving at high speed, the fog lights are directly turned on or off, and the user is reminded to drive safely through the HU, and the status of the fog lights is displayed on the IC.

[0057] In an exemplary embodiment of the present disclosure, the method may further include:

[0058] Obtaining the vehicle's environmental information: obtaining the amount of rain and light conditions in the vehicle's environment detected by the Rain Light Sensor (RLS), and obtaining the clarity of the vehicle's front field of view detected by the Front Camera Module (FCM).

[0059] BCM can connect to RLS via Local Interconnect Network (LIN) line for data exchange. BCM can connect to FCM via CAN bus for data exchange. BCM can determine whether it is insufficient light due to night or heavy rain through RLS, and BCM can determine whether the current field of view is clear based on the field of view information fed back by FCM.

[0060] Among them, RLS detects rainfall and light conditions by real-time monitoring of rainfall and light in order to determine the weather and light conditions caused by the weather. The weather may include: day or night, and sunny or rainy. Light conditions may include: sufficient light and insufficient light. Insufficient light means that the light intensity in the environment where the detected vehicle is located is less than the set light intensity threshold, and sufficient light means that the light intensity in the environment where the detected vehicle is located is greater than or equal to the set light intensity threshold.

[0061] FCM is used to detect the clarity of the front field of view, and to judge the visibility of the weather environment by the obstruction of the field of view, so as to identify weather such as wind, frost, rain and snow, and complement RLS to judge the severe weather conditions of the current weather. Whether the field of view is clear can be judged by the field of view picture in front of the vehicle obtained by FCM, and the visibility of the field of view in front of the vehicle is judged according to the field of view picture in front of the vehicle, and then it is determined whether the field of view is clear. Unclear field of view means that the visibility of the field of view in front of the vehicle is lower than the set visibility threshold, and clear field of view means that the visibility of the field of view in front of the vehicle is higher than or equal to the set visibility threshold. Existing solutions can be used to judge the visibility of the field of view in front of the vehicle according to the field of view picture in front of the vehicle. For example, the field of view picture can be input into a pre-established visibility judgment model, which is not limited or elaborated in this embodiment.

[0062] In one example, controlling the turning on or off of the fog lamp according to the acquired information may include:

[0063] When at least one of the following conditions is met: insufficient light, current rainfall is greater than or equal to a set threshold, or vision is unclear, the fog lights are controlled to be on.

[0064] The BCM uses RLS to determine whether there is insufficient light due to night or heavy rain, and uses FCM to determine whether the view in front of the vehicle is clear. When the BCM determines that there is at least one of heavy rain, insufficient light and unclear view, the fog lights are controlled to be on.

[0065] BCM controlling the fog lights to be in the on state may include: BCM determining whether the current fog lights are in the on state, if in the on state, not performing the opening operation and ending; if in the off state, BCM directly controls the fog lights to turn on, or BCM turns on the fog lights after interacting with the user through HU.

[0066] In one example, controlling the turning on or off of the fog lamp according to the acquired information may include:

[0067] When the light is sufficient and the vision is clear, the fog lights are controlled to be off; or, when the current rainfall is less than the set threshold and the vision is clear, the fog lights are controlled to be off.

[0068] BCM determines through RLS whether there is insufficient light due to night or heavy rain, and through FCM whether the view in front of the vehicle is clear. When BCM determines that there is sufficient light and the view is clear, the fog lights are controlled to be off; or, when BCM determines that the rainfall is light and the view is clear, the fog lights are controlled to be off; or, when BCM determines that it is a sunny day and the view is clear, the fog lights are controlled to be off.

[0069] BCM controlling the fog lights to be in the off state may include: BCM determining whether the current fog lights are in the off state, if in the off state, not performing the opening operation and ending; if in the on state, BCM directly controls the fog lights to be off, or BCM interacts with the user through HU and then turns off the fog lights.

[0070] In an exemplary embodiment of the present disclosure, when at least one of the following conditions is met: insufficient light, current rainfall is greater than or equal to a set threshold, or the field of view is unclear, the following may also be included:

[0071] Adjust the sensitivity of the emergency brake to the highest setting to reduce the gap between the brake disc and the wheel hub.

[0072] When at least one of the following conditions is met: insufficient light, current rainfall greater than or equal to the set threshold, or unclear vision, the BCM controls the fog lights to turn on and actively and safely intervenes in the vehicle, reserves brake preload in advance, adjusts the sensitivity of emergency braking to the highest, and reduces the gap between the brake disc and the wheel hub. It can actively and safely intervene in bad weather conditions such as rain, snow, fog, etc. to increase driving safety.

[0073] In one example, when at least one of the following conditions is met: insufficient light, current rainfall greater than or equal to a set threshold, or unclear vision, and the vehicle is running at a low speed, the sensitivity of the emergency brake is adjusted to the highest level to reduce the gap between the brake disc and the wheel hub. The BCM determines the urgency of the situation by the vehicle speed sent by the ESC, reserves the brake preload in advance, and reduces the gap between the brake disc and the wheel hub. The BCM actively intervenes in the vehicle's safety according to the vehicle's urgency to increase driving safety.

[0074] The low-speed operation of the vehicle refers to the running speed of the vehicle being lower than the first preset speed in any of the above embodiments.

[0075] In an exemplary embodiment of the present disclosure, when at least one of the following conditions is met: insufficient light, current rainfall is greater than or equal to a set threshold, or the field of view is unclear, the following may also be included:

[0076] Turn on the double flash and alarm.

[0077] When at least one of the following conditions is met: insufficient light, current rainfall greater than or equal to the set threshold, or unclear vision, the BCM controls the fog lights to turn on, turns on the hazard lights, and issues an alarm to increase driving safety.

[0078] In an exemplary embodiment of the present disclosure, when at least one of the following conditions is met: insufficient light, current rainfall is greater than or equal to a set threshold, or the field of view is unclear, the following may also be included:

[0079] Obtain the running speed of the vehicle; when the running speed of the vehicle is greater than or equal to the second preset speed, perform speed limit processing to control the maximum running speed of the vehicle to be less than or equal to the set speed, and the set speed is less than the second preset speed.

[0080] When at least one of the following conditions is met: insufficient light, current rainfall greater than or equal to the set threshold, or unclear vision, the BCM controls the fog lights to turn on and actively and safely intervenes in the vehicle. When the vehicle is running at high speed, the speed limit function is turned on to limit the speed. It can actively and safely intervene in bad weather conditions such as rain, snow, fog, etc. to increase driving safety.

[0081] The value of the set speed may be determined based on experience, information about the road the vehicle is on, or weather conditions, and this embodiment will not be limited or elaborated on. In one example, the value of the set speed may be 30 km / h.

[0082] In an exemplary embodiment of the present disclosure, when the light is insufficient, the method may further include:

[0083] Control the vehicle's headlights to be on.

[0084] BCM uses RLS to determine whether there is insufficient light due to night or heavy rain. When there is insufficient light, BCM drives the headlights to turn on, increasing driving safety.

[0085] In an exemplary embodiment of the present disclosure, a vehicle lighting control method may include:

[0086] After the vehicle starts to be powered on, the engine of a traditional fuel vehicle starts running, and the ECM sends the engine running status signal to the CAN. Or the VCU of a hybrid and new energy vehicle is powered on with high voltage, and the VCU sends the vehicle high voltage power-on and normal running status to the CAN. The BMS receives the ECM or VCU running status information through the CAN signal to determine that the vehicle is in a normal starting and running state.

[0087] BCM uses RLS to determine whether it is night or heavy rain that causes insufficient light. If there is insufficient light, BCM drives the headlights to turn on. And BCM determines whether the field of view is clear based on the field of view information fed back by FCM. When there is sufficient light, BCM determines whether the current field of view is clear based on the field of view information fed back by FCM. When the field of view is clear and there is no heavy rain blocking it, BCM determines the current on state of the fog lights. If the fog lights are currently on, BCM turns off the fog lights, and the IC displays that the fog lights are off, and the end is completed. If BCM determines that the current fog lights are off, it ends.

[0088] When BCM determines that there is heavy rain or the vision is not clear, BCM combines the received ESC vehicle speed signal to determine whether the vehicle is currently traveling at a low or high speed.

[0089] When the BCM determines that the vehicle is currently driving at a low speed and the field of vision is not clear, the vehicle sensitivity is adjusted to the highest level, the gap between the brake disc and the wheel hub is reduced, and emergency braking is prepared at any time. The BCM also determines whether the current fog light status is on. If it is on, the process ends; if it is not on, the BCM requests the HU to interact with the user to confirm whether to turn on the fog light. If the user chooses not to turn it on, the process ends; if the user chooses to turn it on, the BCM turns on the fog light, and the IC displays that the fog light is on, and the process ends.

[0090] When BCM determines that the vehicle is currently driving at high speed and the vision is not clear, BCM determines whether the fog lights are currently on. If not, the fog lights are turned on directly and the IC displays that the fog lights are turned on. BCM requests HU to remind the user that it is rainy and foggy weather, please pay attention to safe driving. And turn on the speed limit function, and remind the user to limit the speed of the vehicle, the maximum speed is 30km / h, and control the vehicle to turn on the double flash and alarm, and end. If the fog lights are currently on, BCM requests HU to remind the user that it is rainy and foggy weather, please pay attention to safe driving, and turn on the speed limit function, and remind the user to limit the speed of the entire vehicle, the maximum speed is 30km / h, and control the double flash and alarm to turn on, and end.

[0091] The vehicle lighting control method provided by the disclosed embodiment can determine whether to turn on the fog lights according to the judgment of the real-time weather and environmental conditions, so as to avoid unnecessary losses caused by users forgetting to turn on the fog lights. It can automatically turn off the fog lights by identifying the environmental conditions to reduce the abuse of fog lights. It can also accurately identify the use conditions of the fog lights, and accurately push the fog light turning-on requirements to the user through the human-computer interaction system, so that the user can decide whether to turn on the fog lights according to the actual situation, which not only avoids users turning on the fog lights by mistake, but also avoids the actual application scenarios where users forget or do not know how to use the fog lights, and improves the use of fog lights in specific environments. And in bad weather such as rain, snow and fog, it can actively intervene in safety to increase driving safety.

[0092] Figure 2 The structural block diagram of the vehicle body controller provided by the embodiment of the present disclosure is as follows: Figure 2 As shown, the vehicle body controller may include: a memory 21 and a processor 22 .

[0093] The memory is used to store execution instructions, and the processor can be a central processing unit (CPU), or an application specific integrated circuit (ASIC), or one or more integrated circuits that implement the embodiment of the present invention. When the body controller is running, the processor communicates with the memory, and the processor calls the execution instruction to perform the following operations:

[0095] The fog lamp is controlled to be turned on or off according to the acquired information, wherein the acquired information includes the environment information where the vehicle is located.

[0096] In an exemplary embodiment of the present disclosure, before the processor controls the turning on or off of the fog lamp according to the acquired information, the processor is further configured to:

[0097] The running speed of the vehicle is obtained, and the urgency of the current working condition of the vehicle is determined according to the running speed. The obtained information also includes: the urgency of the current working condition of the vehicle.

[0100] When the running speed is greater than or equal to the first preset speed, determining that the current operating state of the vehicle is a first emergency state;

[0101] When the running speed is less than the first preset speed, it is determined that the current operating condition of the vehicle is a second emergency state, and the urgency of the second emergency state is lower than the urgency of the first emergency state.

[0102] The processor controls the turning on or off of the fog lamp according to the acquired information, which may include:

[0103] When the current working condition is the first emergency state, directly controlling the fog lamp to be in an on or off state according to the environmental information of the vehicle;
