Patent number: 11087149Abstract: An ECU is applied to a vehicle system that is provided with lateral sensors which acquire distance information expressing a distance to an object that is located at a position on a lateral side of a vehicle. When distance information on the object is acquired by the lateral sensors, a judgement is made by the ECU as to whether or not the object is a predetermined moving object that moves relative to the vehicle. The ECU determines that the object is a target to be subjected to contact avoidance processing for avoiding contact with the object, based on a result of judging whether or not the object for which the distance information is acquired is a moving object.Type: GrantFiled: July 11, 2017Date of Patent: August 10, 2021Assignee: DENSO CORPORATIONInventors: Taketo Harada, Mitsuyasu Matsuura, Yosuke Miyamoto
