Abstract

Disclosed herein is a safety stoppage device and method for safety stoppage using a brake system of an autonomous vehicle, wherein the brake system includes a brake-control unit and wheel brakes; the autonomous vehicle is provided with control networks and sensors for monitoring the autonomous vehicle surroundings and motion, and a signaling processing system for processing sensor signals enabling an autonomous drive mode thereof. It is continuously predicted where a drivable space exists, based on data from the sensors and sensor fusion, and calculated a safe trajectory to a stop within the drivable space, that is sent to the brake-control unit and stored therein; and the brake-control unit is shielded against electromagnetic compatibility problems and arranged to monitor if the control networks are operational, and if determined incapacitated, control the autonomous vehicle to follow the most recently calculated safe trajectory to a stop within the drivable space using differential braking of the wheel brakes thereof in order to effectuate steering.
