Description

Technical Field

[0001] This invention relates to the field of intelligent vehicle technology, and in particular to a method, device, equipment and medium for switching lights. Background Technology

[0002] The intelligent high / low beam control function based on visual perception can automatically switch between high and low beams by recognizing ambient light levels and detecting road targets ahead at night (such as vehicle targets, vehicle taillights, and vehicle headlights), providing drivers with a smarter and more convenient driving experience.

[0003] However, visual perception is highly dependent on ambient light conditions, and nighttime scenarios suffer from limitations in visual perception performance due to limited lighting. This is especially true in driving scenarios where there are highly reflective passive light sources such as road signs ahead: for example, at night when there are no vehicles nearby, signs outside the coverage area of ​​the low beams cannot be perceived when the vehicle's low beams are on. However, when the vehicle switches to high beams, the light source shines on the sign, creating a strong reflection, which in turn causes the vehicle to switch off the high beams. While the sign is still in sight, the transition between target detection and high / low beam switching is mutually causal, leading to frequent headlight switching, user complaints, and driving hazards. Summary of the Invention

[0004] This invention provides a method, apparatus, device, and medium for switching headlights to solve the problem of driving safety issues and poor user experience caused by repeated switching between high and low beams due to passive light sources at night.

[0005] According to one aspect of the present invention, a light switching method is provided, comprising:

[0006] Set the headlight cooling control conditions based on the target vehicle speed, the vehicle longitudinal acceleration threshold, and the passive light source speed threshold.

[0007] If the headlights of the current vehicle are in automatic control mode, and the current vehicle completes the target number of high and low beam switching operations within the switching judgment time, then the headlight cooling control will be performed on the current vehicle according to the headlight cooling control conditions and the current vehicle status.

[0008] According to another aspect of the present invention, a light switching device is provided, comprising:

[0009] The headlight cooling control condition determination module is used to set headlight cooling control conditions based on the target vehicle speed, vehicle longitudinal acceleration threshold, and passive light source speed threshold.

[0010] The headlight cooling control module is used to control the headlight cooling of the current vehicle if the headlights are in automatic control mode and the current vehicle completes the target number of high and low beam switching operations within the switching judgment time. This is based on the headlight cooling control conditions and the current vehicle status.

[0011] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0012] At least one processor; and

[0013] A memory communicatively connected to the at least one processor; wherein,

[0014] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the light switching method according to any embodiment of the present invention.

[0015] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the light switching method according to any embodiment of the present invention.

[0016] The technical solution of this invention sets headlight cooling control conditions based on the target vehicle speed, vehicle longitudinal acceleration threshold, and passive light source speed threshold. If the vehicle's headlights are in automatic control mode and the vehicle completes the target number of high / low beam switching operations within the switching judgment time, headlight cooling control is applied to the vehicle based on the headlight cooling control conditions and the vehicle's current state. In this solution, by determining that the vehicle has completed the target number of high / low beam switching operations within the switching judgment time, it is determined that the vehicle has detected a possible passive light source. Therefore, based on the headlight cooling control conditions and the vehicle's current state, the automatic headlight control mode is turned off, preventing repeated high / low beam switching of the headlights. This achieves headlight cooling control for the vehicle, solving the problem of unsafe driving and poor user experience caused by repeated high / low beam switching due to passive light sources at night. It avoids repeated high / low beam switching caused by passive light sources at night, improving driving safety and user experience.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] Example 1

[0027] Figure 1This is a flowchart of a headlight switching method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where repeated switching between high and low beams of a vehicle is avoided. The method can be executed by a headlight switching device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0028] S110. Set the lighting cooling control conditions based on the target vehicle speed, the vehicle longitudinal acceleration threshold, and the passive light source speed threshold.

[0029] The target vehicle speed can be a pre-set vehicle speed. The vehicle longitudinal acceleration threshold can be a pre-set lower limit for vehicle longitudinal acceleration. The passive light source speed threshold can be used to describe the upper limit of the motion speed of the passive light source detected by the vehicle.

[0030] Generally, different models of vehicles produced by the same manufacturer may have different target speeds. The longitudinal acceleration threshold for a vehicle can be 0 m / s². 2 The passive light source speed threshold can be, but is not limited to, 5 km / h. It is understood that the target vehicle speed, vehicle longitudinal acceleration threshold, and passive light source speed threshold can be set independently based on specific vehicle configuration parameters and actual driving conditions.

[0031] In this embodiment of the invention, a target vehicle speed, a vehicle longitudinal acceleration threshold, and a passive light source speed threshold can be set according to the current vehicle configuration parameters and driving conditions. This ensures that the current vehicle speed is not less than the target vehicle speed, the current vehicle bus acceleration is not less than the vehicle longitudinal acceleration threshold, and the passive light source speed detected by the current vehicle is not greater than the passive light source speed threshold, which are used as lighting cooling control conditions.

[0032] S120. If the headlights of the current vehicle are in automatic control mode, and the current vehicle completes the high and low beam switching operation for the target number of rounds within the switching judgment time, then the headlight cooling control is performed on the current vehicle according to the headlight cooling control conditions and the current vehicle status.

[0033] The switching judgment time can be a pre-set time for the vehicle to complete a target number of high / low beam switching operations. The target number of rounds can be a pre-set number of rounds. For example, the target number of rounds can include, but is not limited to, 2 rounds. The high / low beam switching operation can be an operation of switching between different light types. For example, switching from low beam to high beam and then back to low beam is one round of switching, and switching from high beam to low beam and then back to high beam can also be understood as one round of switching. The current vehicle status can be used to describe the current driving condition of the vehicle. Optionally, the current vehicle status can include, but is not limited to, the current vehicle speed, the current vehicle longitudinal acceleration, and the speed of the passive light source detected by the current vehicle. The light cooling control can be to no longer control the high / low beam of the vehicle through the automatic control gear of the interior lights.

[0034] In this embodiment of the invention, if the headlight activation type of the current vehicle is controlled by the automatic control mode, the operation time for the current vehicle to complete the high / low beam switching operation for the target number of rounds is compared with the switching judgment time. If the current vehicle completes the high / low beam switching operation for the target number of rounds within the switching judgment time, it can be determined that the current vehicle has recognized a passive light source. Then, based on the headlight cooling control conditions and the current vehicle status, the duration for turning off the automatic headlight control mode is determined. During the time when the automatic headlight control mode is turned off, the user is prompted to manually control the headlights to achieve headlight cooling control of the current vehicle.

[0035] The technical solution of this invention sets headlight cooling control conditions based on the target vehicle speed, vehicle longitudinal acceleration threshold, and passive light source speed threshold. If the vehicle's headlights are in automatic control mode and the vehicle completes the target number of high / low beam switching operations within the switching judgment time, headlight cooling control is applied to the vehicle based on the headlight cooling control conditions and the vehicle's current state. In this solution, by determining that the vehicle has completed the target number of high / low beam switching operations within the switching judgment time, it is determined that the vehicle has detected a possible passive light source. Therefore, based on the headlight cooling control conditions and the vehicle's current state, the automatic headlight control mode is turned off, preventing repeated high / low beam switching of the headlights. This achieves headlight cooling control for the vehicle, solving the problem of unsafe driving and poor user experience caused by repeated high / low beam switching due to passive light sources at night. It avoids repeated high / low beam switching caused by passive light sources at night, improving driving safety and user experience.

[0036] Example 2

[0037] Figure 2This is a flowchart of a headlight switching method provided in Embodiment 2 of the present invention. This embodiment is based on the above embodiment and is further specified, providing specific optional implementation methods for controlling the vehicle headlights after the headlight cooling control of the current vehicle has ended. Figure 2 As shown, the method includes:

[0038] S210. Set the lighting cooling control conditions based on the target vehicle speed, the vehicle longitudinal acceleration threshold, and the passive light source speed threshold.

[0039] S220. If the headlights of the current vehicle are in automatic control mode, and the current vehicle completes the high and low beam switching operation for the target number of rounds within the switching judgment time, then the headlight cooling control is performed on the current vehicle according to the headlight cooling control conditions and the current vehicle status.

[0040] In an optional embodiment of the present invention, performing headlight cooling control on the current vehicle based on headlight cooling control conditions and the current vehicle state may include: when it is determined that the current vehicle state meets the headlight cooling control conditions, performing headlight cooling control on the current vehicle for a first cooling duration; when it is determined that the current vehicle state does not meet the headlight cooling control conditions, performing headlight cooling control on the current vehicle for a second cooling duration.

[0041] The first cooling time is set when the current vehicle condition meets the headlight cooling control conditions, and the headlights are not controlled via the automatic headlight control mode. The second cooling time is set when the current vehicle condition does not meet the headlight cooling control conditions, and the headlights are not controlled via the automatic headlight control mode.

[0042] In this embodiment of the invention, the current vehicle speed, the current vehicle's longitudinal acceleration, and the speed of the passive light source detected by the current vehicle can be determined based on the current vehicle state. If the current vehicle speed is greater than or equal to the target vehicle speed, the current vehicle's longitudinal acceleration is greater than or equal to a vehicle longitudinal acceleration threshold, and the speed of the passive light source detected by the current vehicle is less than or equal to a passive light source speed threshold, then the current vehicle state is determined to meet the headlight cooling control conditions, and therefore the vehicle headlights are not controlled via automatic control during the first cooling period. If any of the aforementioned headlight cooling control conditions are not met, the current vehicle state is determined not to meet the headlight cooling control conditions, and therefore the vehicle headlights are not controlled via automatic control during the second cooling period.

[0043] In an optional embodiment of the present invention, controlling the headlight cooling of the current vehicle according to a first cooling duration may include: during the first cooling duration, not generating a control command for the high / low beams of the current vehicle, and generating a manual headlight control voice signal; controlling the headlight cooling of the current vehicle according to a second cooling duration may include: during the second cooling duration, not generating a control command for the high / low beams of the current vehicle, and generating a manual headlight control voice signal.

[0044] The manual headlight control voice signal can be a pre-recorded signal prompting the user to manually control the headlights. For example, the manual headlight control voice signal may include, but is not limited to, playing "Ambient interference exists; please manually control the headlights according to the actual situation" through a speaker, and / or displaying the text "Ambient interference exists; please manually control the headlights according to the actual situation" through the vehicle's display screen.

[0045] In this embodiment of the invention, if the current vehicle state meets the headlight cooling control conditions, then during the first cooling period, no control command for the current vehicle's high / low beam headlights is generated to avoid controlling the vehicle's headlights through automatic control. Instead, a manual headlight control voice signal is generated to prompt the user to perform manual headlight control. If the current vehicle state does not meet the headlight cooling control conditions, then during the second cooling period, no control command for the current vehicle's high / low beam headlights is generated to avoid controlling the vehicle's headlights through automatic control. Instead, a manual headlight control voice signal is generated to prompt the user to perform manual headlight control.

[0046] In an optional embodiment of the present invention, the switching determination time may include: determining it based on the following formula: Among them, T A This indicates the switching judgment time, where 'a' represents the first time parameter, and 'D' represents the switching judgment time. A Δv represents the distance between the vehicle and the target passive light source when the vehicle first switches between high and low beams, and Δv represents the relative speed between the vehicle and the target passive light source when the vehicle detects the target passive light source.

[0047] The first time parameter can be a coefficient determined based on the historical driving data of the vehicle's two-wheel high / low beam switching operation. The target passive light source can be a passive light source detected when the vehicle performs its first high / low beam switching operation.

[0048] In an optional embodiment of the present invention, the first cooling duration may include being determined based on the following formula: Among them, T B 'b' represents the first cooling time, 'b' represents the second time parameter, and 'D' represents the second cooling time parameter. BΔv represents the distance between the current vehicle and the target passive light source when the vehicle performs the high / low beam switching operation on the target wheel, and Δv represents the relative speed between the current vehicle and the target passive light source when the vehicle detects the target passive light source.

[0049] The target wheel can be the last wheel in the target wheel count. For example, if the target wheel count is 2, then the target wheel is the second wheel. The second time parameter can be a coefficient set according to the headlight cooling control requirements when the current vehicle state meets the headlight cooling control conditions. For example, the second time parameter can be, but is not limited to, 110%.

[0050] In an optional embodiment of the present invention, the second cooling duration includes: determined based on the following formula: Among them, T C c represents the second cooling time, and D represents the third time parameter. B Δv represents the distance between the current vehicle and the target passive light source when the vehicle performs the high / low beam switching operation on the target wheel, and Δv represents the relative speed between the current vehicle and the target passive light source when the vehicle detects the target passive light source.

[0051] The third time parameter can be a coefficient set according to the lighting cooling control requirements when the current vehicle state does not meet the lighting cooling control conditions. The third time parameter can be, but is not limited to, 90%.

[0052] S230. When the cooling time is reached to match the current vehicle lighting cooling control, and the lighting mode is in automatic control mode, the current vehicle lighting is controlled according to the automatic control mode.

[0053] In this embodiment of the invention, if the current vehicle headlight cooling control time reaches the corresponding cooling time, and the user does not perform manual control within the cooling time, i.e. the headlight mode is in automatic control mode, then the automatic control mode is further restored to control the headlights of the current vehicle.

[0054] Optionally, if the current vehicle status meets the lighting cooling control conditions, the cooling time is the first cooling time. Once the first cooling time is reached and the lighting mode is set to automatic control, the vehicle's lights are controlled according to the automatic control mode. Alternatively, if the current vehicle status meets the lighting cooling control conditions, the cooling time is the second cooling time. Once the second cooling time is reached and the lighting mode is set to automatic control, the vehicle's lights are controlled according to the automatic control mode.

[0055] Figure 3 This is a schematic diagram of an intelligent cooling control process for high and low beam headlights provided in Embodiment 2 of the present invention. Figure 3 As shown, the intelligent cooling control process for high and low beam headlights includes the following steps:

[0056] Step 1: Confirm that the premise for starting the headlight switching method of this scheme is that the current vehicle headlight control mode is in AUTO mode (automatic control mode) and the headlights are in low beam mode. Then, define switching from low beam to high beam and then back to low beam as one round of high beam switching operation.

[0057] Step 2: Define the switching judgment time as T. A , If the vehicle completes two rounds of high / low beam switching operations within the switching judgment time, proceed to step 3.

[0058] Step 3: Determine the current vehicle status. If the current vehicle speed V ≥ 60 km / h and the current vehicle longitudinal acceleration Ax ≥ 0 m / s², then... 2 If the speed of the target passive light source detected by the current vehicle is Vobject≤0km / h, then proceed to step 4; if any of the conditions is not met, then proceed to step 5.

[0059] Step 4: The vehicle headlights enter the headlight cooling control, during the first cooling period. Inside, the system no longer sends control commands for high and low beams to the current vehicle's actuator, and simultaneously issues a text prompt through the instrument panel: "Environmental interference exists. Please manually control the high beams according to the actual situation."

[0060] Step 5: The vehicle headlights enter the headlight cooling control, during the second cooling period. Inside, the system no longer sends control commands for high and low beams to the current vehicle's actuator, and simultaneously issues a text prompt through the instrument panel: "Environmental interference exists. Please manually control the high beams according to the actual situation."

[0061] Step 6: After the cooling period ends, check the high beam control status. If it is still in AUTO mode, re-enter the automatic control mode to control the lights and restore normal operation.

[0062] In this solution, by adding headlight cooling control, the frequent switching of high and low beam control caused by the detection of state changes by passive light sources such as speed limit signs is avoided. It has the advantage of adaptability. By using vehicle status and target attributes, a dynamic cooling time control method with low computing power dependence and high coupling of vehicle status is achieved, which improves the intelligent control performance of high and low beam headlights and avoids the frequent switching of high and low beam headlight control caused by the detection of state changes by passive light sources at night.

[0063] The technical solution of this invention sets light cooling control conditions based on the target vehicle speed, vehicle longitudinal acceleration threshold, and passive light source speed threshold. If the current vehicle's headlights are in automatic control mode and the current vehicle completes the target number of high and low beam switching operations within the switching judgment time, then light cooling control is performed on the current vehicle based on the light cooling control conditions and the current vehicle status. Furthermore, if a cooling time matching the current vehicle's light cooling control is reached and the light mode is in automatic control mode, then the current vehicle's lights are controlled according to the automatic control mode. In this solution, by determining the number of high / low beam switching operations completed by the current vehicle within the specified switching time, it is determined that the current vehicle has detected a potential passive light source. Based on the light cooling control conditions and the current vehicle status, the automatic light control mode is turned off to prevent repeated high / low beam switching of the vehicle's headlights, thus achieving light cooling control. The automatic control mode can be restored after the cooling time is reached, providing a more intelligent solution to meet user needs. This solution addresses the safety concerns and poor user experience caused by repeated high / low beam switching due to passive light sources at night, improving driving safety and user experience.

[0066] The headlight cooling control condition determination module 310 is used to set headlight cooling control conditions based on the target vehicle speed, the vehicle longitudinal acceleration threshold, and the passive light source speed threshold.

[0067] The headlight cooling control module 320 is used to control the headlight cooling of the current vehicle according to the headlight cooling control conditions and the current vehicle status if the headlights of the current vehicle are in automatic control mode and the current vehicle completes the target number of high and low beam switching operations within the switching judgment time.

[0068] The technical solution of this invention sets headlight cooling control conditions based on the target vehicle speed, vehicle longitudinal acceleration threshold, and passive light source speed threshold. If the vehicle's headlights are in automatic control mode and the vehicle completes the target number of high / low beam switching operations within the switching judgment time, headlight cooling control is applied to the vehicle based on the headlight cooling control conditions and the vehicle's current state. In this solution, by determining that the vehicle has completed the target number of high / low beam switching operations within the switching judgment time, it is determined that the vehicle has detected a possible passive light source. Therefore, based on the headlight cooling control conditions and the vehicle's current state, the automatic headlight control mode is turned off, preventing repeated high / low beam switching of the headlights. This achieves headlight cooling control for the vehicle, solving the problem of unsafe driving and poor user experience caused by repeated high / low beam switching due to passive light sources at night. It avoids repeated high / low beam switching caused by passive light sources at night, improving driving safety and user experience.

[0070] Optionally, the headlight cooling control module 320 includes a first headlight cooling control unit and a second headlight cooling control unit; the first headlight cooling control unit is used to perform headlight cooling control on the current vehicle for a first cooling duration when it is determined that the current vehicle state meets the headlight cooling control conditions. The second headlight cooling control unit is used to perform headlight cooling control on the current vehicle for a second cooling duration when it is determined that the current vehicle state does not meet the headlight cooling control conditions.

[0071] Optionally, the first headlight cooling control unit is specifically configured to, during the first cooling period, not generate control commands for high / low beam headlights of the current vehicle, and to generate a manual headlight control voice signal. The second headlight cooling control unit is specifically configured to, during the second cooling period, not generate control commands for high / low beam headlights of the current vehicle, and to generate a manual headlight control voice signal.

A Δv represents the distance between the current vehicle and the target passive light source when the current vehicle performs its first high / low beam switching operation, and Δv represents the relative speed between the current vehicle and the target passive light source when the current vehicle detects the target passive light source.

[0076] Optionally, the first cooling duration includes a value determined based on the following formula:

[0077]

[0078] Among them, T B Let b represent the first cooling time, b represent the second time parameter, and D represent the second cooling time.
