TRAILER TRACKING COMMERCIAL VEHICLE AND AUTOMOTIVE SIDE VIEW MIRROR SYSTEM
A system for automotive trailer tracking side view mirrors where the side view mirrors are dynamically adjusted to follow and track a trailer, semi-trailer, or other towed load during turning, backing or other maneuvers. The driver is provided with an optimized view of the rear of the trailer without the need to manually adjust side view mirrors. As the vehicle and trailer turn and articulate, the side view mirror system automatically adjusts to turn, rotate, and follow the trailer. The system may provide imaging sensors, digital cameras, Lidar sensors, or other sensor modalities as input to an electronic control module. The control module is provided with image or sensor data regarding the location, angle or orientation of optical markers or targets installed on the trailer. Alternatively, the control module is provided with high resolution imaging or sensor data and applies machine vision and object recognition algorithm to identify the position of the trailer. The control modules provides a control signal output to the side view mirror motors and actuators, to dynamically adjust the side view mirrors, with a frequency response of less than 100 ms in order to provide the driver with a clear unobstructed view.
