Fig. 2 is a flowchart illustrating a vehicle lamp control method that may be performed in the system architecture of the first control module 101 and the second control module 102 shown in fig. 1, according to an exemplary embodiment of the present application. Referring to fig. 2, the flow chart of the vehicle lamp control method at least includes steps S210 to S240, and is described in detail as follows:

in step S210, a lamp turn-on message is received.

In an embodiment of the present application, the lamp turn-on message is a lamp turn-on message generated when the user performs the lamp turn-on control according to the driving scene requirement, and specifically includes that the user controls the lamp control switch to control the lamp based on the lamp turn-on scene, where the lamp control switch may be a physical control switch, such as a lamp switch knob, a lamp switch key, or may be a virtual lamp switch, for example, a virtual button in the central control display device, or may be an external control device connected when the related technician is used to test the vehicle. After receiving the start signal, the signal processing device of the central control device converts the switch pulse signal into a lamp start message required by a transmission medium such as a bus, a wireless transmission protocol and the like, and the specific type of the message is not particularly limited.

In an embodiment of the present application, after receiving the lamp turn-on message, the method further includes monitoring an on state of the lamp switch at the vehicle end, and if the on state of the lamp switch at the vehicle end is on, determining an operation state of the lamp set. Wherein the lamp set operating state includes normal operation and abnormal operation.

The lamp set refers to an integral device of a car lamp control system, and comprises a power-on device, a bulb, a controller, a control main board and related lamp set circuits.

In one embodiment of the present application, if the running state of the light bank is abnormal, the current turning-on operation of the vehicle-end light is terminated, and a light bank abnormal state message is generated according to the light bank running abnormal state, so as to feed back the light bank running abnormal state.

In one embodiment of the present application, if the lamp set is in a normal running state, a lamp on message is sent to the first control module, and the first light control module controls the first light to be turned on and sends a light on request to the second light control module.

In an embodiment of the application, the fault detection is performed on the car lamp module by receiving the car lamp starting message, so that the problem that the delay time length caused by failure in starting the lamp cannot be determined or errors are determined can be avoided, and the accuracy of determining the delay time length is improved.

In one embodiment of the application, after receiving the lamp on message, the first control module is controlled to start the first lamp based on the lamp on message and monitor the first lamp on state, meanwhile, the first control module sends the lamp on message to the second control module to control the second control module to start the second lamp and monitor the second lamp on state, and the lamp on state display information is generated based on the first lamp on state and the second lamp on state and sent to the display terminal to display the lamp on state. And after the car lamp is synchronously started, the car lamp state is displayed, and the domain controller is synchronously utilized to display the car lamp starting state information, so that a user intuitively observes the car lamp starting state. The domain controller is a light processing domain controller of a vehicle and is used for controlling and managing a light system and a device of the vehicle.

In an embodiment of the present application, the above-mentioned lamp on-state display information needs to be generated after receiving the lamp on-state message and controlling the lamp to turn on each time, and in some implementable scenarios, if there is at least one lamp on-state display message in the on-state of the first lamp and the second lamp, it may be shown that the lamp is turned on, for example, if the on-state of the first lamp and the on-state of the second lamp are both on, the display flag of the lamp on-state is on; if the first car light is started, the second car light is not started, and the display mark is still started; if the first car light and the second car light are not started, the display mark of the car light on state is not started. In some other embodiments of the present application, a specific on state and an unopened state may be displayed during display according to a specific on state of each vehicle lamp, and alert of an unopened reason.

In step S220, the first control module is triggered to send a lamp turn-on message to the second control module based on the lamp turn-on message to control the second control module to turn on the second lamp.

In an embodiment of the present application, the first control module is configured to control on/off of the first lamp.

In one embodiment of the present application, after receiving the lamp turn-on message, if there is no time delay for turning on the lamp, the first control module is controlled to turn on the first lamp immediately.

In step S230, if the presence status of the on-time duration is not present, when the second lamp is successfully turned on, the second control module is controlled to feed back a second lamp on-completion message to the first control module.

In one embodiment of the present application, after triggering the first control module to send a lamp on message to the second control module, a presence state of a delay time in the vehicle controller is detected. In some other embodiments of the present application, the delay time is stored in a vehicle information storage area of the vehicle, and then the presence state of the delay time information in the vehicle information is detected. Wherein the presence state includes both presence and absence states.

It should be noted that, the existence mode of the above-mentioned light-on delay time length in the vehicle machine may be a recording mode such as a control instruction mode, a vehicle machine information mode, a controller delay mark mode, etc., which is only an exemplary example, and the existence mode of the above-mentioned light-on delay time length is not specifically limited.

In some other embodiments of the present application, a receiving counter of the lamp turn-on message may be set in the controller, after triggering the first control module to send the lamp turn-on message to the second control module, count information in the receiving counter of the lamp turn-on message is determined, if the lamp turn-on message is first received, when the second lamp is turned on successfully, the second control module is controlled to feed back a second lamp turn-on completion message to the first control module.

And if the lamp starting message is not received for the first time, controlling the lamp according to the time delay duration of starting the lamp.

It should be noted that the "first time" in the above description may specifically refer to a case that the lamp turn-on message is received for the first time in the initial turn-on process of the vehicle life cycle, or when the vehicle needs to set the time delay of turn-on, or when the vehicle is refitted, maintained, and related parts are replaced and there is a counter for receiving the lamp turn-on message, the time delay of turn-on is determined and set for the first time, or when the lamp turn-on message is received again after the count information of the counter is cleared based on the requirements of related technicians or users, which may be both interpreted as the first time of receiving the lamp turn-on message.

In one embodiment of the present application, if the existence state of the turn-on delay time length is nonexistent, when the second vehicle lamp is turned on abnormally, the second vehicle lamp turn-on abnormal message is fed back to the first control module, and the first control module is triggered to terminate the determination operation of the turn-on delay time length based on the second vehicle lamp turn-on abnormal message.

In one embodiment of the present application, if the existence state of the on-lamp delay time length is present, the lamp control is performed on the lamp according to the on-lamp delay time length.

In step S240, a light-on delay time is determined according to the sending time and the receiving time, so as to control the light according to the light-on delay time.

In an embodiment of the present application, the sending time is a time when the first control module sends the lamp turn-on message to the second control module, and the receiving time is a time when the first control module receives the feedback message that the second lamp turn-on is completed.

In one embodiment of the present application, half of the time period from the sending time to the receiving time is determined as the turn-on delay time length, and the turn-on delay time length is stored in the preset vehicle information storage area, so that the vehicle lamp is controlled according to the turn-on delay time length. The time period from the sending time to the receiving time is the sum of two communication time periods from sending of the communication information to receiving of the feedback information, namely the communication time period from the sending time to the receiving time is the sum of the communication time periods from the first control module to the second control module of sending the lamp starting message and the communication time period from the first control module to receiving of the second lamp starting to finish feedback, so that the time period from the sending time to the receiving time is marked as T, and the time delay time of starting the lamp is marked as T/2.

In an embodiment of the present application, based on a determination accuracy requirement of a time delay of turning on a lamp, the method for determining a time delay of turning on a lamp further includes that a first control module sends a lamp on message to a second control module, meanwhile, controls a first lamp to be turned on based on the lamp on message, starts timing at a sending time, ends a first timing when the first lamp is turned on and receives a feedback message of completion of turning on the first lamp, obtains a time delay of the first lamp, ends a second timing when the first control module receives a feedback message of completion of turning on the second lamp, and obtains a time delay of the second lamp.

And determining half of the absolute value of the difference between the second vehicle lamp timing duration and the first vehicle lamp timing duration as the on-lamp time delay duration. The optimization scheme can effectively improve the time length determination error of the time length determination process of the turn-on time delay, for example, the time length of the second vehicle lamp is 70 milliseconds, the time length of the first vehicle lamp is 20 milliseconds, when the time length of the time delay is not optimized, half of the time length of the second vehicle lamp is determined to be the time length of the turn-on time delay, namely, the time length of the turn-on time delay is 35 milliseconds, if the time length of the time delay is required to be optimized, half of the absolute value of the difference value between the time length of the second vehicle lamp and the time length of the first vehicle lamp is determined to be the time length of the turn-on time delay, namely, the time length of the turn-on time delay after optimization is 25 milliseconds, and the problem that the turn-on time is not synchronous still can not be solved when the time length error of the time delay is excessively increased.

In one embodiment of the application, the confirmed time delay time length is stored in a preset vehicle information storage area, one real-time scene of the preset vehicle information storage area is the vehicle information storage area in the vehicle central control system, and the time delay time length is stored in the preset vehicle information storage area, so that relevant technicians can conveniently call and check the time delay time length information.

In one embodiment of the present application, controlling the vehicle lamp according to the turn-on delay time includes controlling the first vehicle lamp to turn on according to the delay time and also includes controlling the first vehicle lamp to turn off according to the delay time.

Under the scene of turning on the lamp, receiving a new lamp turn-on message, controlling the first lamp to be turned on in a delayed time of turning on the lamp by the first control module, and triggering the first control module to send the new lamp turn-on message to the second control module based on the new lamp turn-on message so as to control the second control module to turn on the second lamp. After the time delay time length is confirmed, the first vehicle lamp is controlled to be turned on in a time delay mode according to the time delay time length, the time delay is identical to the signal transmission time of the second vehicle lamp, the first vehicle lamp and the second vehicle lamp can be turned on at the same time, and the time difference between the turning on of the vehicle lamps is avoided.

And under the light-off scene, receiving a light-off message, controlling the first light to be turned off when the light-on delay time is delayed by the first control module, and triggering the first control module to send the light-off message to the second control module based on the light-off message so as to control the second control module to turn off the second light. The time delay duration is also used for controlling when the car lamp is turned off, so that the car lamp can be turned off to realize synchronous control.

In an embodiment of the present application, detecting and correcting the delay time length is further included, specifically including obtaining an actual delay time length according to a preset detection period, determining a time length difference value between the actual delay time length and the turn-on delay time length, and correcting the turn-on delay time length according to the actual delay time length if the time length difference value is greater than a preset delay correction threshold.

In one embodiment of the present application, it may be determined based on experimental data and a relevant human eye observation frequency range, and when the duration deviation of the on-lamp delay duration is less than 50 ms, the delay duration deviation existing between the lamps may be ignored.

The actual delay time is determined according to the actual sending time and the actual receiving time after each turn-on message of the car lamp is received after the first turn-on message of the car lamp is received.

Referring to fig. 3, fig. 3 is a flowchart illustrating a specific vehicle lamp control method according to an exemplary embodiment of the present application. The specific method may be applied to the implementation environment shown in fig. 1, or may be applied to other exemplary implementation environments, and specifically configured in other devices, where the implementation environment to which the apparatus is applied is not limited in this embodiment.

Firstly, it should be noted that, in a specific vehicle lamp control method in the exemplary embodiment shown in fig. 3, the left domain controller is consistent with the first control module in the foregoing embodiment, and the corresponding left light is consistent with the first vehicle lamp in the foregoing embodiment; the right domain controller is consistent with the second control module in the embodiment, the right light is consistent with the second vehicle lamp in the embodiment, the light coordination module is a submodule of the left light control module, namely a submodule of the first control module, and the time delay duration T is consistent with the on-light time delay duration in the embodiment.

As shown in fig. 3, in a specific embodiment of the present application, the light control of the present invention includes the following steps:

step S11 is to judge whether the user has a requirement of turning on a lamp according to the headlight setting signal (for example, the user sets the light switch to the off position to indicate that the user does not have a requirement of turning on a lamp, the user sets the light switch to the position to indicate that the user has a requirement of turning on a floodlight, and sets the light switch to the dipped headlight to indicate that the user has a requirement of turning on a floodlight), wherein one of the headlight setting signals is obtained through a vehicle central control display screen, or obtained through other modes, and the obtaining mode of the headlight setting signal is not limited.

Step S12, when the user does not have the requirement of turning on the lamp, the lamp is not controlled to be lighted; when the user has a light-on demand, step S13 is skipped, and it is determined whether lighting is allowed or not, for example, whether the vehicle power supply range is the OFF range or not, according to the vehicle state, and the vehicle headlight is in a fault state.

Step S14 is to not control the lighting of the light when the light coordination module determines that the lighting of the light is not allowed at this time.

Step S15 is that when the user has a light-on demand and the vehicle allows the light to be lighted, the light coordination module sends a light lighting request.

Step S16 is to light the right headlight, the light coordination module of the left domain controller is required to send a light lighting request to the right light control module of the right domain controller through the CAN bus, and then the right light control module controls the lighting of the right headlight. The middle part is required to be transmitted through a CAN signal, so that time delay exists, and the right light control module immediately controls the right headlight to be lighted after receiving the light lighting request;

step S17 is that the right light control module should detect the right headlight on state, and the right headlight on state is fed back to the light coordination module by the right light control module in step S18 for self-learning of the time delay duration of the left headlight and headlight state display.

Step S19 is to judge whether the light is first lighted after the left light control module receives the light starting request.

In a specific embodiment of the present application, the existence state of the light-on delay time length may also be determined after the left light control module receives the light-on request. The judging step is consistent with the description of the time delay time and the first-time starting state of the vehicle lamp in the above embodiment, and redundant explanation is not made in this specific embodiment.

Step S100 is to calculate the left light lighting delay time length T by self-learning according to the total time length from the moment of sending the light lighting request to the moment of receiving the right light to be in the lighting state if the light is lighted for the first time. Referring to fig. 4, fig. 4 is a flowchart illustrating a specific delay time determining method according to an exemplary embodiment of the present application.

As shown in fig. 4, in a specific embodiment of the present application, step S101 is to start timing after the coordination module sends a light starting request, and in step S102, determine whether the right headlight sent by the right light control module is in a turned-on state, and not receive the previous timing; in step S103, after the coordination module receives that the right headlight is in the on state, a time T0 from when the light on request is sent to when the right headlight is received in the on state is calculated, where the time is a total communication time from when the communication signal is sent to when the communication signal is fed back, and step S104 is to calculate a delay time duration t=t0/2 for the left headlight to be on, and record the time T in the left light control module.

Step S20, if the light is first lighted, the left light control module has no time delay time length T for lighting the headlight, and at the moment, the left light control module immediately controls the left headlight to be lighted after receiving the light starting request; and detecting a left headlight on state by the left light control module in step S21; in step S22, the left light control module feeds back the left headlight on state to the light coordination module for headlight state display.

Step S23 is that if the light is not first lighted, the left light control module starts timing after receiving the light starting request, and in step S24, the left light control module judges whether the timing time length is greater than T, wherein the left light is not controlled to be lighted in the time period from the time when the light starting request is received to the time length reaching T.

And S25, when the timing time is longer than or equal to T, the left light control module controls the left headlight to be lighted, so that the left headlight and the right headlight are synchronously lighted.

Step S26 is that the left lamp light control module feeds back the lighting state of the left headlight to the light coordination module for headlight state display.
