Detailed Description
In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
As shown in fig. 1 and 2, this embodiment provides an automotive a-pillar mini-LED interaction lamp, which is characterized in that: the intelligent automobile comprises an A column 1, a mini-LED driving module, a mini-LED array 2, an MCU module, an Ethernet module, an automobile automatic driving domain controller and an intelligent cabin domain controller, wherein the mini-LED array 2 is arranged on the wall surface of the A column 1, which is positioned in an automobile. The mini-LED driving module and the MCU module are powered by a power supply module, and the power supply module adopts a conventional voltage stabilizing chip to convert a 12V vehicle body power supply into 3.3V voltage for the mini-LED driving module and the MCU module.
The mini-LED array 2 is electrically connected with a mini-LED driving module, the mini-LED driving module is electrically connected with an MCU module, and the MCU module is respectively electrically connected with a vehicle autopilot domain controller and an intelligent cockpit domain controller through an Ethernet module.
As shown in fig. 3, the ethernet module of the present embodiment adopts an ethernet chip with a model of LAN8760, the mini-LED driving module of the present embodiment adopts an LED matrix driving chip with a model of LP5891Q, and supports multi-chip cascading, and in the present embodiment, only two chips are needed to realize thousand-level pixel control. The MCU module of this embodiment adopts MCU chips of model NXP S32K3 series, and S32K344 is preferred in this embodiment. The mini-LED array 2 of the embodiment comprises 1920 red mini-LEDs, and each support 0-1 mA of brightness is adjustable.
As shown in fig. 1, the vehicle autopilot controller provides information in a blind area shielded by an a-pillar 1 outside a vehicle to the MCU module through the ethernet module according to information sent by an original vehicle-mounted camera and an ultrasonic radar. When the vehicle is running, the a-pillar 1 displays whether or not obstacle information such as a person, a vehicle, a tree, etc. is present in the blind area.
