[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0046] First, Figure 1 A flow chart of a method for controlling a car light show provided by an embodiment of the present disclosure, such as Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling a car light show, comprising:

[0047] S1: The central control module determines whether the car meets the preset light show start conditions according to the light show mode command.

[0048] S2: When the preset light show start conditions are met, the central control module sends a control signal to the body control module according to the light show mode command.

[0049] S3: The body control module controls the car light show module according to the control signal.

[0050] In the disclosed embodiment, the user can turn on or off the light show through the central control screen, or can use a mobile phone APP to turn on or off the light show. In the process of turning on the light show, whether through the central control screen or the mobile phone APP, a light show mode instruction will be issued to the central control module. After receiving the light show mode instruction, the central control module determines whether the car meets the preset light show start-up conditions; the central control module determines whether the car meets the preset light show start-up conditions when the user selects the light show mode. If the preset light show start-up conditions are met, the user can normally select the light show mode. If the preset light show start-up conditions are not met, the user cannot normally select the light show mode; it can also be determined whether the car meets the preset light show start-up conditions after the user selects the light show mode. When the preset light show start-up conditions are met, the central control module controls the communication module to send a control signal to the body control module, and the body control module controls the car light show module according to the received control signal; wherein, the control signal can be a CAN signal, which is a signal transmitted in a controller area network (Controller Area Network, referred to as CAN).

[0051] In the disclosed embodiment, the car light show module works under the control of a PWM signal, and the rhythm of the light show is changed by changing the duty cycle of the PWM signal.

[0052] In some examples, preset conditions for starting the light show include: the car is in P gear, the battery power is greater than 60% of the maximum power, the car power is fully on, and the car is not in a start-stop state.

[0053] Furthermore, when the car is performing a light show, the car changes state and no longer meets the preset light show start-up conditions, and the body control module stops controlling the light show module.

[0054] In some examples, the central control module determines whether the vehicle meets the preset light show start conditions according to the light show mode instruction, including:

[0055] S11: presetting a first light show mode, a second light show mode and a third light show mode, and correspondingly generating a first light show mode instruction, a second light show mode instruction and a third light show mode instruction.

[0056] Specifically, three light show modes are set in the embodiment of the present disclosure, and the three light show modes change the rhythm of the light show by changing the duty cycle of the PWM signal. The first light show mode instruction can be expressed as 0x1: (Mode 1); the second light show mode instruction can be expressed as 0x2: (Mode 1); and the third light show mode instruction can be expressed as 0x3: (Mode 1).

[0057] S12: After receiving any one of the first light show mode command, the second light show mode command and the third light show mode command, the central control module determines whether the vehicle is in P gear, whether the battery power is greater than 60% of the maximum power, whether the vehicle power is in a fully on state, and whether the vehicle is in a start-stop state.

[0058] In some examples, the body control module controls the car light show module according to the control signal, including: the body control module sends a PWM signal to the light show module according to the control signal, and the light show module performs a light show according to the received PWM signal.

[0059] In some examples, when the preset light show start conditions are met, the central control module sends a control signal to the body control module according to the light show mode instruction, including:

[0060] The central control module sends a light show mode instruction to the communication module, and the communication module determines the light show mode according to the light show mode instruction;

[0061] When the communication module receives the first light show mode instruction, it sends a first control signal to the body control module;

[0062] When the communication module receives the second light show mode instruction, it sends a second control signal to the body control module;

[0063] When the communication module receives the third light show mode instruction, it sends a third control signal to the body control module.

[0064] In some examples, the body control module sends a PWM signal to the light show module according to the control signal, and the light show module performs a light show according to the received PWM signal, including:

[0065] The body control module sends a first PWM signal to the light show module according to the first control signal, and the light show module performs a light show according to the first PWM signal;

[0066] The body control module sends a second PWM signal to the light show module according to the second control signal, and the light show module performs a light show according to the second PWM signal;

[0067] The body control module sends a third PWM signal to the light show module according to the third control signal, and the light show module performs a light show according to the third PWM signal.

[0068] Furthermore, the duty cycle of the first PWM signal is 40%, the duty cycle of the second PWM signal is 60%, and the duty cycle of the third PWM signal is 80%. It is understandable that the duty cycle of the first PWM signal, the duty cycle of the second PWM signal, and the duty cycle of the third PWM signal can be adjusted in actual vehicle production and vehicle design to meet the light show rhythm required by different models.

[0069] It should be understood that in the embodiment of the present disclosure, three light show modes are used as an example. In actual vehicle production and vehicle design, four, five or more light show modes may be included; accordingly, a fourth PWM signal and a fifth PWM signal with different duty cycles are included to control the light show module to perform light shows with different rhythms.

[0070] Embodiment 1:

[0071] In the disclosed embodiment, the light show includes three modes, and the first light show mode, the second light show mode and the third light show mode are preset, and the first light show mode instruction, the second light show mode instruction and the third light show mode instruction are generated accordingly. After the user selects the light show mode, the light show mode instruction is sent to the central control module. After receiving any one of the first light show mode instruction, the second light show mode instruction and the third light show mode instruction, the central control module determines whether the car meets the preset light show start-up conditions.

[0072] The preset conditions for starting the light show include: 1. The car is in P gear; 2. The battery power is greater than 60% of the maximum power; 3. The car power is fully on; 4. The car is not in the start-stop state, among which the car power includes fully on I GN-ON, partially on I GN-ACC and completely off I GN-OFF. When the car power is fully off I GN-OFF, the light show cannot be performed. When the car power is partially on I GN-ACC, only some areas and functions are powered on, so the light show cannot be performed. In order to ensure the safety of the car during driving, the light show cannot be turned on when the car is in other gears except P gear.

[0073] When the preset light show start conditions are met, the central control module sends a light show mode instruction to the communication module, and the communication module determines the light show mode according to the light show mode instruction; when the communication module receives the first light show mode instruction, it sends a first control signal to the body control module; when the communication module receives the second light show mode instruction, it sends a second control signal to the body control module; when the communication module receives the third light show mode instruction, it sends a third control signal to the body control module. The body control module sends a first PWM signal to the light show module according to the first control signal, and the duty cycle of the first PWM signal is 40%, and the light show module performs a light show according to the first PWM signal; the body control module sends a second PWM signal to the light show module according to the second control signal, and the duty cycle of the second PWM signal is 60%, and the light show module performs a light show according to the second PWM signal; the body control module sends a third PWM signal to the light show module according to the third control signal, and the duty cycle of the third PWM signal is 80%, and the light show module performs a light show according to the third PWM signal; PWM signals with different duty cycles can achieve different light show rhythmic effects.

[0074] Embodiment 2:

[0075] When the car is performing a light show, the user can turn off the light show through the central control module. The central control module controls the communication module to send a shutdown control signal to the body control module. After receiving the shutdown control signal, the body control module stops sending PWM signals to the light show module.

[0076] When the car status changes and no longer meets the preset light show start conditions, for example: 1. The car changes from P gear to other gears; 2. The battery power drops below 60% of the maximum power; 3. The car power is not fully turned on IGN-ON; 4. The car is in the start-stop state; any of these conditions are considered to no longer meet the preset light show start conditions. The central control module controls the communication module to send a shutdown control signal to the body control module, and the body control module no longer sends a PWM signal to the light show module.

[0077] Furthermore, when the light show is turned off, the central control module sends a light show turn-off instruction 0x0: No_Request to the communication module.

[0078] Second, Figure 2 A block diagram of a car light show control system provided by an embodiment of the present disclosure, such as Figure 2As shown, based on the same inventive concept, the disclosed embodiment also provides a car light show control system, the system includes: a central control module, a body control module and a light show module; the central control module is used to determine whether the car meets the preset light show start-up conditions according to the light show mode instruction; when the preset light show start-up conditions are met, the body control module sends a control signal to the body control module according to the light show mode instruction; the body control module is used to control the car light show module according to the control signal. Among them, the central control module can be the I HU (Infotainment Head Unit) of the car; preferably, the body control module can be the right domain controller of the car.

[0079] In some examples, the automobile light show control system further includes: a communication module; the communication module is used to receive a light show mode instruction sent by the central control module, determine the light show mode according to the light show mode instruction, and send a control signal to the body control module.

[0080] Furthermore, the body control module sends a PWM signal to the light show module according to the control signal; and the light show module performs a light show according to the received PWM signal.

[0081] Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
