PURPOSE: A space searching method of automatic steering parking support device for cars, using an ultrasonic sensor is provided to improve efficiency and accuracy of space searching by performing an independent space searching when the ultrasonic sensor operates. CONSTITUTION: An automatic steering parking support device for cars comprises multiple slave ultrasonic sensors, and an LIN master controller. The LIN master controller transmits initialization and diagnosis orders to each slave ultrasonic sensor. The LIN master controller transmits a space searching order to the slave ultrasonic sensor which has completed the initialization and diagnosis. The LIN master controller asks the result data to one of the slave ultrasonic sensors. A method of automatic steering parking support for cars comprises the steps of: transmitting the initialization and diagnosis orders to the multiple slave ultrasonic sensors; transmitting the space searching order to each slave ultrasonic sensor which gas completed the initialization and diagnosis; asking the result data of space searching to one of the slave ultrasonic sensors connected to the LIN communications. |
