Abstract
Official abstract text for this publication.
A detector includes a plurality of sensors and is configured to detect a user in preliminarily set detection areas. The sensors are arrayed horizontally at a rear portion of a vehicle such that the detection areas of the adjacent sensors overlap with each other. If any one of the sensors detects the user and outputs a detection signal (first detection signal), a threshold for a detection signal of one of the sensors adjacent to the sensor (second detection signal) is raised and the first and second detection signals are converted to first and second binary signals, respectively. A rear door is opened if the second binary signal has an output period that is contained in an output period of the first binary signal.
First claim
Opening claim text (preview).
1 . A vehicle door open-close control device comprising: a detector disposed in the vicinity of a vehicle door and configured to detect a user in a preliminarily set detection area; and a controller configured to open the vehicle door if the detector detects the user; wherein the detector comprises a plurality of sensors horizontally arrayed in the vicinity of the door, wherein the plurality of sensors is disposed so as to allow detection areas of adjacent sensors to overlap with each other, wherein the controller compares, when any of the sensors detects the user, a first detection signal of the sensor and a second detection signal of one of the sensors adjacent to the sensor, and opens the door if the detection signals satisfy a predetermined relation. 2 . The vehicle door open-close control device according to claim 1 , wherein the controller converts the first detection signal to a first binary signal with reference to a first threshold set to a predetermined signal level and converts the second detection signal to a second binary signal with reference to a second threshold larger than the first threshold, compares an output period of the first binary signal and an output period of the second binary signal, and opens the door if the output period of the second binary signal is contained in the output period of the first binary signal. 3 . The vehicle door open-close control device according to claim 1 , wherein the controller converts the first detection signal to a first binary signal with reference to a threshold set to a predetermined signal level and converts the second detection signal to a second binary signal with reference to the threshold, compares an output period of the first binary signal and an output period of the second binary signal, and opens the door if the output period of the second binary signal is contained in the output period of the first binary signal. 4 . The vehicle door open-close control device according to claim 3 , wherein the controller opens the door if the second binary signal rises after the first binary signal rises and the first binary signal falls after the second binary signal falls. 5 . The vehicle door open-close control device according to claim 1 , wherein the controller compares an output period of the first detection signal and an output period of the second detection signal at a predetermined signal level, and opens the door if the output period of the second detection signal is contained in the output period of the first detection signal.
