carma-system-3.4.0

carma-platform release version 3.4.0 is comprised of four major enhancements. First, a steering limiter was added in order to prevent Carma from taking turns that present a risk of vehicle rollover. Second, updates were made to the health_monitor to allow for graceful handling of sensor failure, including control handover to the human driver. Third, carma-messenger was updated to detect nearby automated vehicles via DSRC. And fourth, functionality was added to carma-messenger to allow for requesting, receiving, and displaying truck safety info from a passing Carma truck via DSRC while vehicles are in motion. Along with the above enhancements, several bug fixes and CI related enhancements are included in this release.
