Abstract
A sensor system for an autonomous driving vehicle (ADV) includes a sensor interface coupled to a plurality of sensors, a host interface coupled to a host system of the ADV, and an adaptive sensor transfer unit coupled between the sensor interface and the host interface. The adaptive sensor transfer unit includes a sensor monitoring module configured to monitor a data rate of sensor data received from a sensor; and a configuration control module configured to: receive a target data rate from the host via the host interface; receiving a monitored data rate of the sensor data; and controlling a data rate of the sensor data within a threshold of the target data rate.
