Abstract

Single pair Ethernet in combination with Ethernet endpoints provides a scalable basis for the direct control of sensors and actuators in zonal vehicle networks. As recently shown, this approach is also ideal for driving high-resolution light functions. The ability to transmit different parallel data streams to actuators opens a wide field for new applications. Here, we show a method for stabilising high-resolution light projections in driving operation. The stabilization of the light image is based on an inertial measurement unit that records vehicle movements in real-time. An algorithm in a central control unit continuously calculates correction values for the position and distortion compensation of the light distribution and sends this data to the lamp via Ethernet, preferably 10BASE-T1S. Two methods are combined in a proof of concept: predictive correction with video data rate and image shifting in the headlamp’s frame buffer at high frequency.
