Method for collision avoidance of a motor vehicle with an emergency vehicle and a related system and motor vehicle
A method for collision avoidance of a motor vehicle with an emergency vehicle includes detecting surroundings of the motor vehicle using an optical detection arrangement, detecting wider surroundings of the motor vehicle using an acoustic detection arrangement, and detecting traffic users in the surroundings. The wider surroundings are investigated to detect a signal indicative of an emergency signal of the emergency vehicle, and a trajectory of motion for each of the detected traffic user is determined. If emergency signal is detected, a further investigation is undertaken to detect behavior that is indicative of a hazardous situation in the surroundings. If the behavior indicative of the hazardous situation detected, then the method also includes locating a position of the emergency vehicle and determining a trajectory of motion for the emergency vehicle based on the position of the emergency vehicle and the determined trajectories of motion of the detected traffic users. In addition, it is determined whether a collision of the motor vehicle with the emergency vehicle will occur for a current trajectory of motion of the motor vehicle based on the determined trajectory of motion for the emergency vehicle, and a warning is output to a user of the motor vehicle based on determining that the collision will occur.
