By way of example only, the process of vehicle external ambience light system 200 for user alert and remote control is described below.
When the vehicle is stolen, the door is subjected to external force and/or the vehicle body moves, and the door stress sensor and/or the vehicle body position sensor detect the external force and/or the movement and convert the external force and/or the movement into an anti-theft alarm signal.
The burglar alarm signal is set to a higher priority, and when the burglar alarm signal is generated, it CAN grasp the control right of the CAN bus, so that the burglar alarm signal is transmitted to each node of the CAN network through the CAN bus, and the controller 220, as a constituent unit of the CAN network, CAN also receive the burglar alarm signal forwarded by the CAN transceiver 210.
After receiving the burglar alarm signal, the controller 220 determines that the received signal is the burglar alarm signal, performs noise reduction, feature detection and feature extraction on the burglar alarm signal, invokes a preset program in the external memory 240 to generate a PWM driving signal according to the processed burglar alarm signal, and sends the generated PWM driving signal to the second atmosphere lamp 260 and the TBOX 270.
the second ambience lamp 260 is lighted and in a flashing state after receiving the PWM driving signal sent by the controller 220, and plays a role in warning and deterring criminals.
After receiving the PWM driving signal transmitted from the controller 220, the TBOX 270 forwards the PWM driving signal to the mobile terminal 290 through the TSP280, and the mobile terminal 290 receives the burglar alarm signal to alert the user that the vehicle is stolen. The user issues the setting information after knowing that the vehicle is being stolen. The controller 220 receives the setting information through the TSP280 and the TBOX 270 and changes the lighting manner of the atmosphere lamp at the corresponding position of the vehicle external atmosphere lamp system according to the contents of the setting information. The content of the lighting pattern may include the brightness and/or frequency of the atmosphere lamp.
For example, the setting information content may be to increase the brightness of the second ambience lamp 260. The controller 220 receives the setting information and increases the current level of the driving signal, so that the brightness of the second atmosphere lamp 260 is increased.
for example, the setting information content may be to increase the blinking frequency of the ambience light. The controller increases the duty cycle of the driving signal after receiving the setting information, and the second ambience lamp 260 is flashed at an accelerated rate.
