Hereinafter, a method for processing multi-mode information by the domain controller to control the vehicle lamp according to the embodiment of the present application will be described in detail with reference to fig. 3.

Referring to fig. 3, fig. 3 is a flowchart of a method for processing multi-mode information by a domain controller to control a vehicle lamp according to an embodiment of the present application. As shown in fig. 3, a method for a domain controller to process multi-mode information to control a vehicle lamp is applied to a vehicle domain control system of a vehicle, the vehicle domain control system includes a cabin domain controller, a body domain controller connected with the cabin domain controller, and an information acquisition module connected with the body domain controller, the information acquisition module includes a plurality of photosensitive modules arranged on the vehicle, the method includes:

step 301, the vehicle body domain controller sends a first request message to the cabin domain controller.

The first request message is used for requesting the cabin domain controller to predict whether road information in a preset road information set exists in front of a driving route of the vehicle, and the road information set comprises different reference road information. Specifically, the vehicle body domain controller sends a first request message to the cabin domain controller, so that the cabin domain controller predicts whether road information in a preset road information set exists in front of a running route of the vehicle, and data support is provided for determining whether to adjust the working frequency of the photosensitive module. The reference road information may be a shielding facility with a smaller shielding area on the road, for example, information of a culvert on the road or information of a bridge on the road, and the reference road information may be set according to actual requirements, which is not limited in particular.

Step 302, the cabin domain controller responds to the first request message to collect comprehensive information at the current time point.

Wherein the integrated information includes navigation information, a current time point, location information, and map information of the vehicle. After receiving the first request message, the cabin domain controller starts to collect navigation information, current time point, position information and map information of the vehicle at the current time point. It is to be understood that the kind of information contained in the integrated information may be set according to actual requirements, and may further include, for example, thermal imaging information obtained by the thermal imaging device, and information such as distance information between the front and rear vehicles obtained by the distance sensor, which is not limited herein.

And step 303, predicting target road information in front of the driving route of the vehicle according to the comprehensive information.

Wherein, the target road information in front of the driving route of the vehicle is determined according to the navigation information, the position information and the map information of the vehicle in the comprehensive information.

Step 304, if the reference road information identical to the target road information is found from the road information set and the current time point is detected to be within a preset first time interval, first adjustment information is sent to the vehicle body domain controller.

The first adjusting information characterizes information indicating the vehicle body domain controller to adjust the working frequency of a single photosensitive module in the plurality of photosensitive modules to different working frequencies. The road information set comprises different reference road information, the reference road information can be shielding facilities with smaller shielding areas on the road, and if the reference road information identical to the target road information is found out from the road information set, the shielding facilities with smaller shielding areas on the road in front of the vehicle are determined. If it is determined that a shielding facility with a smaller shielding area exists on a road in front of a vehicle and the current time point is detected to be in a preset first time interval, first adjusting information is sent to a vehicle body domain controller. The first time interval may be a preset traffic jam time period, such as an off-shift time period or an on-shift time period. In the traffic jam time period, the vehicle running speed is slower, and when the vehicle passes through the shielding facility, the vehicle head can pass through first, so that different photosensitive modules can be adjusted to different working frequencies, and energy consumption is saved. For example, the first time interval is between seven and nine in the morning, if the acquired current time point is seven and three ten in the morning, the current time point is determined to be in the first time interval, so that first adjusting information is determined to instruct the vehicle body domain controller to adjust up the information of the working frequency of a single photosensitive module in the plurality of photosensitive modules, and energy consumption is saved.

And step 305, the vehicle body domain controller responds to the first regulation information, and predicts a first time period required by the vehicle to pass through the shielding facility in the target road information under the current road condition according to the comprehensive information.

After the vehicle body domain controller receives the first adjusting information, responding to the first adjusting information, predicting a first time length which is required for the vehicle to pass through a shielding facility in the target road information under the current road condition according to the comprehensive information obtained by the cabin domain controller, and providing data support for the working frequency of the follow-up specific adjustment.

Step 306, acquiring a working frequency set corresponding to the first time length.

The working frequency in the working frequency set is the frequency at which a single photosensitive module in the plurality of photosensitive modules collects the information of the change of the light around the vehicle and reports the information. The different time lengths correspond to different working frequency sets, so that the light information is timely obtained through the adjusted photosensitive module, and meanwhile, the energy consumption is saved. The working frequency set comprises a plurality of working frequencies, and different light sensing modules correspond to different working frequencies in the plurality of working frequencies, so that the adjusted working frequencies more meet the actual requirements. For example, when the vehicle speed is 20 codes, the highest working frequency in the working frequency set is acquired 3 times per second, the lowest working frequency in the working frequency set is acquired 1 time per second, and the light change information is reported to the vehicle body domain controller after being acquired once. When the vehicle speed is 30 codes, the highest working frequency in the working frequency set is collected 5 times per second, and the lowest working frequency in the working frequency set is collected 2 times per second. Thereby improving the frequency of collection and reporting of the induction module, and further improving the accuracy of switching on and off the car lamp.

Step 307, adjusting the working frequency of each photosensitive module in the plurality of photosensitive modules according to the first duration and the working frequency set, so as to obtain first light change information of the environment where the vehicle is located.

After the corresponding working frequency set is determined, the frequency of each photosensitive module in the plurality of photosensitive modules is adjusted according to the working frequency set, so that first light change information of the environment where the vehicle is located is obtained, and after the first duration is maintained, the working frequency before adjustment is restored, manual operation is not needed, and the control intelligence is improved.

And 308, controlling the on and off of the vehicle lamp of the vehicle according to the first light change information.

And controlling the opening and closing of the lamp of the vehicle according to the first light change information.

It can be seen that, in this example, whether the operating frequency of sensitization module is adjusted through road information determination, improves the intelligent of adjusting, obtains the first light change information of vehicle place environment through the sensitization module after adjusting, in time discovers the environment light change to in time switch on and off the car light, improve the accuracy of control. And the working frequency of the photosensitive module is adjusted according to the first time spent by the vehicle for shielding facilities in the target road information under the current road condition, so that the photosensitive timeliness of the photosensitive module is ensured, and the energy consumption is saved.

In one possible example, the predicting the target road information in front of the driving route of the vehicle according to the integrated information includes: the cabin domain controller acquires the navigation information, the position information and the map information in the comprehensive information; determining whether a shielding facility for shielding the light of the vehicle is included in front of the driving route according to the navigation information, the position information and the map information, and generating a determination result; and generating the target road information according to the determination result.

In a specific example, the cabin domain controller comprises an air download module, the air download module supports an air download technology, map information can be updated in real time through the air download module of the cabin domain controller, and the reliability of the obtained target road information is improved. The navigation information and the position information of the navigation module in the cabin controller may be directly acquired, or the navigation information and the position information in the terminal device connected to the cabin controller may be acquired. After the navigation information, the position information and the map information are acquired, the shielding facilities on the route to be driven by the vehicle are determined through the navigation information and the map information, whether the shielding facilities shielding the light rays of the vehicle are included in front of the driving route of the vehicle is determined by combining the position information, a determination result is generated, and target road information is generated according to the determination result.

It can be seen that in the present example, whether or not the shielding facility shielding the light of the vehicle is included in front of the vehicle travel route is determined by the navigation information, the position information, and the map information, and the accuracy of the determination result is improved.

In one possible example, the integrated information may further include movie information acquired by the vehicle-mounted camera, navigation information, position information, map information and movie information in the integrated information are acquired, a shielding facility on a route on which the vehicle is to travel is determined by the navigation information and the map information, whether a shielding facility shielding light of the vehicle is included in front of the vehicle travel route is determined by combining the position information and the movie information, a determination result is generated, and target road information is generated according to the determination result. And further determining whether a shielding facility for shielding the light of the vehicle is included in front of the vehicle driving route according to the film and television information, so that the accuracy of a determination result is improved. It will be appreciated that the integrated information may also include image information, and in particular, without limitation, a determination of whether a vehicle travel path ahead includes an occlusion facility that occludes light from the vehicle may also be made in conjunction with the image information.

In one possible example, the comprehensive information includes vehicle speed information of a vehicle, the body area controller predicts a first time period required for the vehicle to pass through the in-target-road-information shielding facility under the current road condition according to the comprehensive information in response to the first adjustment information, and includes: the vehicle body domain controller acquires the vehicle speed information and the map information in the comprehensive information; and predicting a first time period required for the vehicle to pass through the in-target road information shielding facility under the current road condition according to the map information and the vehicle speed information.

In a specific example, the vehicle speed is different under different road conditions, for example, the vehicle speed during rush hour is lower than the vehicle speed during non-rush hour, and when the vehicle speed is different, the photosensitive module can be adjusted to different working frequencies, so that the energy consumption is saved while the light change information can be timely detected, and the adjustment is more reasonable. The vehicle body domain controller receives first adjustment information, obtains vehicle speed information and map information in comprehensive information, obtains the length of a shielding facility of target road information in the map information, and determines a first time length required to be spent by the vehicle according to the vehicle speed information and the length.

In this example, the map information and the vehicle speed information determine the first duration that the vehicle needs to spend when passing through the shielding facility in the target road information under the current road condition, and data support is provided for subsequent determination of different working frequencies, so that adjustment is more reasonable and intelligent.

In one possible example, the plurality of photosensitive modules includes a first photosensitive module, a second photosensitive module and a third photosensitive module, the first photosensitive module is disposed on a head of the vehicle, the second photosensitive module is disposed on a body of the vehicle, the third photosensitive module is disposed on a tail of the vehicle, the operating frequency of each photosensitive module in the plurality of photosensitive modules is adjusted according to the first duration and the operating frequency set, and the method includes: the vehicle body domain controller searches a first working frequency corresponding to the first photosensitive module, a second working frequency corresponding to the second photosensitive module and a third working frequency corresponding to the third photosensitive module from the working frequency set; and adjusting the working frequency of the first photosensitive module to the first working frequency, and maintaining the working frequency of the first photosensitive module to the first working frequency in the first duration taking the time point adjusted to the first working frequency as the starting time point; and adjusting the working frequency of the second photosensitive module to the second working frequency, and maintaining the working frequency of the second photosensitive module to the second working frequency in the first duration taking the time point adjusted to the second working frequency as the starting time point; and adjusting the working frequency of the third photosensitive module to be the third working frequency, and maintaining the working frequency of the third photosensitive module to be the third working frequency in the first duration taking the time point adjusted to be the third working frequency as the starting time point.

In a specific example, the plurality of photosensitive modules includes a first photosensitive module, a second photosensitive module and a third photosensitive module, the first photosensitive module is disposed on a head of the vehicle, the second photosensitive module is disposed on a body of the vehicle, and the third photosensitive module is disposed on a tail of the vehicle. The photosensitive modules are distributed on the body of the vehicle so as to acquire the change information of light rays around the vehicle in time. After the vehicle body domain controller obtains the corresponding working frequency set, determining a first working frequency corresponding to the first photosensitive module from the working frequency set, similarly determining a second working frequency corresponding to the second photosensitive module from the working frequency set, and determining a third working frequency corresponding to the third photosensitive module from the working frequency set. The working frequencies of the photosensitive modules at different positions are adjusted to different working frequencies, for example, the working frequency of the first photosensitive module is adjusted to the working frequency with the highest working frequency among the three photosensitive modules, so that when a vehicle head enters a shielding facility, the light change can be sensed, and the working frequencies of the photosensitive modules of the vehicle body and the vehicle tail can be lower than the working frequency of the first photosensitive module due to the fact that the light change information is collected, and energy consumption is saved. After the working frequency of the first photosensitive module is adjusted to be the first working frequency, maintaining a first duration, and timely detecting whether the vehicle leaves from the shielding setting; similarly, after the working frequency of the second photosensitive module is adjusted to be the second working frequency, the first time length is maintained; and after the working frequency of the third photosensitive module is adjusted to be the third working frequency, maintaining the first duration. It will be appreciated that the number of photosensitive modules and the position of the photosensitive modules on the vehicle body can be set according to actual requirements, and the present invention is not limited thereto.

In this example, a corresponding operating frequency is set for each of the plurality of photosensitive modules, thereby improving the intelligence of adjustment.

In one possible example, after the predicting the target road information in front of the driving route of the vehicle according to the integrated information, the method further includes: if the cabin domain controller searches the reference road information which is the same as the road information from the road information set and detects that the current time point is in a preset second time interval, second adjusting information is sent to the vehicle body domain controller, and the second adjusting information characterizes and instructs the vehicle body domain controller to adjust the working frequencies of the plurality of photosensitive modules to be the same working frequency; the vehicle body domain controller responds to the second regulation information, and predicts a second time length which is required for the vehicle to pass through the shielding facility in the target road information under the current road condition according to the comprehensive information; acquiring a fourth working frequency corresponding to the second duration, wherein the fourth working frequency is the frequency at which the plurality of photosensitive modules acquire the change of the light around the vehicle and report the change; the frequencies of the plurality of photosensitive modules are adjusted according to the second duration and the fourth operating frequency, so that second light change information of the environment where the vehicle is located is obtained; and controlling the opening and closing of the vehicle lamp of the vehicle according to the second light change information.

In a specific example, if the cabin domain controller finds the same reference road information as the road information from the road information set and detects that the current time point is within a preset second time interval, the cabin domain controller sends second adjustment information to the vehicle body domain controller. The second time interval can be a preset non-working time interval or a time interval with smoother driving, such as a time interval between two to four pm points, and in a time interval with fewer vehicles, the road is smooth, and the vehicles can rapidly drive, so that time consumption is less when the vehicles pass through a shielding facility, and in order to ensure timely acquisition of light change information, the difference of working frequencies between different light sensing modules can be reduced, and the light change information can be timely captured. And the working frequencies of different photosensitive modules are directly adjusted to the same working frequency, so that the adjusting efficiency is improved. At different speeds, the plurality of photosensitive modules of the vehicle correspond to different working frequencies. The vehicle body domain controller responds to the received second regulation information, predicts a second time length required by the vehicle to pass through the shielding facility in the target road information under the current road condition according to the comprehensive information, namely, obtains map information and vehicle speed information of the vehicle in the comprehensive information, determines the length of the shielding facility to be passed through by the vehicle according to the map information, and determines the second time length according to the length and the speed information. And acquiring a fourth operating frequency corresponding to the second time length, and adjusting the frequencies of the plurality of photosensitive modules according to the second time length and the fourth operating frequency to acquire second light change information for controlling the on and off of the lamps of the vehicle.

In this example, it is determined that the operating frequencies of the plurality of photosensitive modules of the vehicle are adjusted to the same operating frequency or different operating frequencies according to the time interval in which the current time point is located, so as to improve the adjustment intelligence. And if the time point of the current time point is the second time interval, the working frequency of the photosensitive module of the vehicle is adjusted to be the same working frequency, so that the adjusting efficiency is improved, the timely acquisition of the light change information is ensured, and the control accuracy is improved.

In one possible example, the plurality of photosensitive modules includes a fourth photosensitive module, a fifth photosensitive module and a sixth photosensitive module, the fourth photosensitive module is disposed on a head of the vehicle, the fifth photosensitive module is disposed on a body of the vehicle, the sixth photosensitive module is disposed on a tail of the vehicle, and the frequency of the plurality of photosensitive modules is adjusted according to the second duration and the fourth operating frequency, including: the vehicle body domain controller adjusts the operating frequency of the fourth photosensitive module, the operating frequency of the fifth photosensitive module and the operating frequency of the sixth photosensitive module to the fourth operating frequency, and maintains the operating frequency of the fourth photosensitive module, the operating frequency of the fifth photosensitive module and the operating frequency of the sixth photosensitive module at the fourth operating frequency within the second duration with the time point adjusted to the fourth operating frequency as the starting time point.
