As shown in fig. 1, the multi-color tunable ambience lamp control system of the present invention is composed of a large sound screen 1 (not shown), a main sound controller 2(HU), a vehicle body control unit 3(BCM), a plurality of ambience lamp control units 4(ALU), and an ambience lamp assembly 5. The ambience lamp assembly 5 is composed of a plurality of ambience lamps 51 connected in parallel, and each ambience lamp 51 is connected to a corresponding ambience lamp control unit 4. The atmosphere lamp 51 is also connected to a battery to achieve long power.
The large sound screen 1 receives a user's command for turning on/off, color and brightness of the atmosphere lamp 51; the large sound screen 1 is connected with the main sound machine controller 2 and can send the switch, color and brightness adjusting instructions of the atmosphere lamp 51 to the main sound machine controller 2. The vehicle body control unit 3 is connected with the main audio controller 3 through a CAN line, and the main audio controller 3 transmits information on the on/off, color and brightness of the atmosphere lamp 51 to the vehicle body control unit 3. And the vehicle body control unit 3 forwards the instruction of the sound host controller 2 to the atmosphere lamp control unit 4 through an LIN line and the atmosphere lamp control unit 4 through the LIN line. After receiving the LIN signal, the ambience lamp control unit 4 controls the duty ratio of the RGB light source of the ambience lamp 51 to adjust and change the brightness and color of the ambience lamp 51. The sound equipment large screen 1 is provided with a switch, a plurality of colors and a brightness adjusting button, and the switch, the colors and the brightness of the atmosphere lamp 51 can be adjusted.
Specifically, the atmosphere lamp control unit 4 and the atmosphere lamp 51 are 12, and can realize 12 colors and 10 brightness adjustments.
When the atmosphere lamp 51 is turned on and off, the atmosphere lamp 51 has a breathing turn-on and turn-off function, specifically: the ambience lamp control unit 4 realizes the breathing turn-on and breathing turn-off effects of the ambience lamp 51 by controlling the duty ratio output of the RGB light sources. The breath lighting time is 2 seconds, the breath extinguishing time is 1.5 seconds, the brightness change in the visual lighting and extinguishing process is uniform, and no brightness mutation exists. In the process of turning on the atmosphere lamp 51 in a breathing mode, if an atmosphere lamp 51 turning-off instruction is received, the atmosphere lamp 51 is turned off immediately; during the breathing turn-off of the atmosphere lamp 51, if the atmosphere lamp 51 is turned on, the atmosphere lamp 51 is gradually turned on.
The atmosphere lamp control unit 4 is provided with a sleep awakening logic module for controlling the atmosphere lamp 51 to keep an off state or enter a working state. The sleep wake-up logic: the atmosphere lamp 51 is connected with the storage battery for long power, when the atmosphere lamp control unit 4 receives an LIN sleep instruction, the atmosphere lamp control unit 4 enters a sleep function, and the atmosphere lamp 51 keeps an off state; when the ambience lamp control unit 4 receives the wake-up signal of the LIN signal, the ambience lamp 51 enters the working state, and the color and brightness are performed according to the received signal.
Atmosphere lamp control unit 4 is equipped with the undulant processing module of voltage, can adjust the atmosphere lamp state according to the voltage value. Such as making atmosphere lamp 51 color and brightness adjustments or entering a self-protected state.
Voltage fluctuation processing:
1. when the voltage of the whole vehicle is less than 16V and 9V, the atmosphere lamp is in a normal working state, and the atmosphere lamp control unit adjusts the color and the brightness of the atmosphere lamp according to the received LIN signal requirement;
2. when the voltage is less than 9V or more than 16V, the atmosphere lamp is in a voltage abnormal stage, the atmosphere lamp is kept turned off, and the atmosphere lamp enters a self-protection state;
3. the voltages 9V and 16V are critical values, and in order to prevent abnormal flicker, a 0.5V return value is added (for example, the abnormal state is less than 8.5V (or more than 16.5V) from the normal state, the normal state is more than 9V (or less than 16V) from the abnormal state), and the default power-on value is the normal state.
The atmosphere lamp control unit 4 is further provided with an LIN signal judgment module for judging whether the transmitted LIN signal is accurate or not. When the atmosphere lamp 51 receives an error signal, the previous state is maintained unchanged by default, and until a correct signal instruction is received, the atmosphere lamp control unit 4 controls the atmosphere lamp 51 to adjust the on-off, color and brightness, so that the signal deviation problem existing in the transfer process of the LIN signal can be avoided.
According to the invention, the whole atmosphere lamp 51 is set to be in a long-power state, if a non-long-power scheme is adopted, the power-saving relay is added in the vehicle body control unit 3, and the whole atmosphere lamp 51 is connected below the power-saving relay, so that the scheme has higher requirement on the loading capacity of the vehicle body control unit 3, and the cost of the vehicle body control unit 3 is increased more.
A control method of a multi-color adjustable atmosphere lamp comprises the following steps:
A. the automobile is ignited and started or awakened to start in sleep, and the driving initialization is carried out on the RGB light source of the atmosphere lamp 51;
B. a user clicks a switch of an atmosphere lamp and 12 colors or 10 brightness adjusting buttons on the large sound screen 1, and the large sound screen 1 sends a switch, a color and a brightness adjusting instruction of the atmosphere lamp 51 to the main sound machine controller 2;
C. the sound equipment main machine controller 2 sends the information of the on-off, brightness and color of the atmosphere lamp 51 to the vehicle body control unit 3 through the CAN line;
D. the vehicle body control unit 3 forwards the instruction of the main audio controller 2 to the atmosphere lamp control unit 4 through an LIN line;
E. after receiving the LIN signal, the atmosphere lamp control unit 4 controls the atmosphere lamp 51 to perform switching, color and brightness adjustment;
e1, if the received 4 instructions are sleep instructions, the control unit 4 enters the sleep function, and the atmosphere lamp 51 keeps off;
e2, if the atmosphere lamp control unit 4 receives the wake-up signal of LIN signal, the atmosphere lamp 51 enters the working state, the color and brightness are executed according to the received signal;
e3, if the atmosphere lamp 51 is in the abnormal voltage stage, the atmosphere lamp keeps turning off and enters a self-protection state;
