The external interface unit is connected with the atmosphere lamp power supply unit, the LIN drive circuit unit, the isolation power supply unit and the CAN drive circuit unit. The isolation power supply unit is respectively connected with the LIN drive circuit unit, the central controller unit and the CAN drive circuit unit, and the central controller unit is respectively connected with the LIN drive circuit unit, the CAN drive circuit unit and the atmosphere lamp power supply unit. The lighting logic control of the automotive trim lamp can be realized, various sensory requirements of passengers in different environments can be met, the passengers can obtain a special visual effect in the automobile, and a unique automotive trim experience is created.

Description

technical field [0001] The invention relates to the technical field of automotive functional lighting control. In this field, it is necessary to realize the lighting logic control function of automotive interior lights, which can meet the various sensory needs of passengers in different environments, and enable passengers to obtain special visual effects inside or outside the car. , enhance the surrounding sense of ambient light, and create a unique automotive interior experience, specifically involving an isolated automotive ambient light controller based on CAN communication. Background technique [0002] With the continuous deepening of technical cooperation among global automakers, the differences in the quality of cars produced by automakers around the world are getting smaller and smaller, and quality is no longer the main difference in car manufacturing. The ambient lighting function has gradually become a key factor affecting consumers' car purchases. Passengers hope...
