Patent number: 11976929Abstract: In a localization apparatus for a vehicle, a landmark detector detects a landmark from camera information acquired from a camera mounted to the vehicle. An associator associates the landmark with a specific set of radar information by setting an error region in which the landmark may exist, selecting, from a radar observation point cluster formed of a set of radar observation points corresponding to a set of radar information acquired from a radar mounted to the vehicle, a radar observation point cluster formed of a set of radar observation points included in the error region, and associating the landmark with the specific set of radar information corresponding to the selected radar observation point cluster. A positional relationship calculator calculates a positional relationship between the landmark and the vehicle based on the specific set of radar information associated with the landmark.Type: GrantFiled: December 21, 2020Date of Patent: May 7, 2024Assignee: DENSO CORPORATIONInventors: Ariya Terani, Itsuki Chiba, Naohiro Fujiwara, Makoto Ohkado, Keisuke Hachisuka

Patent number: 9013269Abstract: A lock release apparatus in a vehicle includes a vehicle unit and a portable device, for an exchange of the first and second reference signals transmitted therebetween from the portable device through human body of the driver toward the right and left hands of the driver onto the first and second interfaces. The signals received by the interfaces are used to set the first and second determination conditions. At a time of a shift lever operation, an interface on a shift lever is used to receive the first determination signal for determining the first determination condition, together with the second determination signal from the other interface for releasing the lock of the shift lever.Type: GrantFiled: February 16, 2011Date of Patent: April 21, 2015Assignee: DENSO CORPORATIONInventors: Keisuke Hachisuka, Osamu Katayama

Patent number: 8467742Abstract: An electrode group is provided in a portable terminal carried by a human body for transmitting a transmission signal to the human body functioning as a transmission medium. The electrode group contains three electrodes arranged respectively at three vertices of an equilateral triangle. Three types of driving electrode pairs are defined as respectively having different combination of optional two electrodes. While changing the driving electrode pairs for use in order one pair by one pair, the transmission signal based on the same transmission data is repeatedly transmitted as many times as the number of driving electrode pairs.Type: GrantFiled: March 16, 2010Date of Patent: June 18, 2013Assignee: DENSO CORPORATIONInventors: Keisuke Hachisuka, Takayuki Shibata, Ryoichi Sugawara

Publication number: 20100121502Abstract: An operation control system includes a transmitter circuit, a transmitter interface, an engine start button switch, a receiver unit and an engine ECU. The transmitter circuit generates a transmission signal and the transmitter interface inputs a communication signal to an operator by converting the transmission signal. The receiver unit receives the communication signal through the operator, when the operator touches the engine start button switch. The engine start button switch detects in-blood alcohol concentration of the operator. The receiver unit generates and applies an engine start control signal in response to output signals of the receiver unit indicative of the operator's engine start operation and alcohol detection result.Type: ApplicationFiled: November 5, 2009Publication date: May 13, 2010Applicant: DENSO CORPORATIONInventors: Osamu Katayama, Keisuke Hachisuka, Ryoichi Sugawara
