Patent number: 11161547Abstract: A parking assistance device includes a pair of left and right sonar devices provided in a vehicle, an obstacle detection controller for determining whether an obstacle present within a determination target distance range on a side of the vehicle is a wall or a curb by comparing a level value of a reflection wave received by one of the sonar devices with each of a first threshold value and a second threshold value that are different from each other, and an automatic parking controller for setting a guiding route for automatic parking depending on a determination result, and the automatic parking controller sets the guiding route requiring a large amount of steering of the vehicle in a case where the determination result indicates a curb, compared with a case where the determination result indicates a wall in the automatic parking in the form of parallel parking.Type: GrantFiled: September 9, 2016Date of Patent: November 2, 2021Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Satoru Inoue, Shinichi Harase, Ryotaro Suzuki, Wataru Tsujita, Tsutomu Asahina, Yoshitsugu Sawa
