And each auxiliary domain controller sends the target light control signal to at least one connected second car lamp in real time when receiving the target light control signal.

When the target light control signal is a flashing light control signal for controlling at least one first vehicle lamp and at least one second vehicle lamp connected with a certain auxiliary domain controller to flash according to a lighting state of 360ms on and 360ms off, the main domain controller calls a plurality of delay parameters which are stored in advance when receiving the target light control signal, then continuously sends a direct drive control signal (i.e. the target light control signal) to one corresponding first vehicle lamp at a time point of TA1.1 according to the zero point of the current moment, so as to control the first vehicle lamp to circularly turn on and off in a flashing mode of 360ms on and 360ms off, and continuously sends a direct drive control signal to the other corresponding first vehicle lamp at a time point of TA1.2, and similarly, continuously sends the direct drive control signal to the other corresponding first vehicle lamp at a time point of TA 1.3; and, at a time point of TB1.1, sending a target light control signal to one auxiliary domain controller through the ethernet so that the auxiliary domain controller controls the corresponding at least one second lamp to blink in the same manner. The auxiliary domain controller sends corresponding direct-drive control signals to each second car lamp in real time according to the received target lamp light control signals, so that the synchronous flickering effect of at least one first car lamp and at least one second car lamp is achieved.

In the embodiment of the application, a plurality of predetermined delay parameters can be obtained under the condition that the target light control signal is received, so that the target light control signal is respectively sent to one first car lamp or one auxiliary domain controller corresponding to each delay parameter through the main domain controller when the time reaches the time point corresponding to each delay parameter based on each delay parameter in the plurality of delay parameters, and at least one first car lamp and at least one second car lamp connected with each auxiliary domain controller are controlled to synchronously turn on and off. According to the method, the transmission delay parameters of the light control signals from the main domain controller to each first car lamp and each auxiliary domain controller can be transmitted, so that when the main domain controller transmits target light control signals, the target light control signals can be transmitted to the first car lamp and the auxiliary domain controller at corresponding time points based on the predetermined delay parameters, and at least one second car lamp connected with the first car lamp and each auxiliary domain controller can be synchronously turned on and off. Therefore, the problems of longer delay time and poorer effect of the synchronous control of the lamplight of the control part of the lamplight synchronous control can be solved, and the use experience of a user is improved.

Optionally, in the process that at least one first car lamp and at least one second car lamp are synchronously turned on and off, the main domain controller and each auxiliary domain controller need to detect or receive an on-off state signal fed back by each car lamp in real time, and count according to the on-off state signal and the lamp efficiency (usually, complete on-off cycle is counted for 1 time in an accumulated manner); and each auxiliary domain controller gathers the count (namely the switching times of on and off) of each car lamp to the main domain controller in real time for verification.

Optionally, when the main domain controller receives the control signal for turning off the light, the main domain controller may send the corresponding control signal for turning off the light to at least one first lamp and each auxiliary domain controller based on the latest delay time parameter, so as to control at least one first lamp and at least one second lamp to stop flashing at the same time, and at the same time, clear the on-off count of each lamp.

S502, when the difference value of the on-off switching times corresponding to any two car lights is larger than a preset threshold value, sending a check signal to at least one first car light and at least one auxiliary domain controller through the main domain controller again so as to redetermine a plurality of delay parameters.

Optionally, when it is determined that the difference of the on-off switching times corresponding to any two lamps reaches a certain degree (can be set according to the test calibration), the main domain controller can be automatically controlled to perform comprehensive checking correction again, and the latest delay parameter is used for covering the storage parameter and is applied to the synchronous action of the current lamp in real time.

Optionally, can also be on the basis of synchronous many car lights on-off, control multiple car lights to open according to certain order and close and form different lamp effect accurate control effect (like music light is shown), can add the motion control of common automobile body spare such as door window, lock, windscreen wiper simultaneously to adapt to the demand of different control scenes, promote vehicle performance and user experience and feel. The system can be suitable for light control of other complex controller architectures, such as a trailer, various complex light effects of light and the like; in addition, if the complex lamp efficiency is required to be accurately controlled, the transmission time of the corresponding lamp driving signal is adaptively adjusted on the basis of the delay parameter calculated in the steps.

The embodiment of the application has the advantages of accurate delay time, differential control and strong universality, and simultaneously simplifies the wire harness distribution structure, reduces the wire harness requirement and reduces the cost.

In the embodiment of the application, the on-off switching signals fed back by each first car lamp and each second car lamp can be obtained while at least one second car lamp connected with each auxiliary domain controller is synchronously on-off, so as to determine the on-off switching times corresponding to each first car lamp and each second car lamp, and therefore, when the difference value of the on-off switching times corresponding to any two car lamps is larger than a preset threshold value, the on-off states of a plurality of car lamps are determined to be asynchronous, and a check signal is required to be sent to at least one first car lamp and at least one auxiliary domain controller again so as to determine a plurality of delay parameters. Therefore, the effect of synchronous control of the lamplight can be further improved, and the use experience of a user is improved.
