Development of a verification method on ultrasonic-based perpendicular parking assist system

This paper presents a verification method on an ultrasonic-based perpendicular parking assist system. The system is an automotive product using ultrasonic sensors and electric power steering to carry out perpendicular parking semi-automatically for consumer convenience. An accurate verification method is required to develop the parking assist system because this system has a risk of crashing into other vehicles while parking. Thus, the standard test specification and parameters of the verification method are proposed to prove the system accurately. Especially, it considers the mechanism of the parking system and risk points of sensors on the system sufficiently. The proposed verification method is proven that it is effective to verify the ultrasonic-based perpendicular parking assist system.
