Publication number: 20240328855Abstract: According to an aspect, a detection device includes: a planar detection device including photodetection elements; point light sources provided correspondingly to the photodetection elements; a light directivity control element disposed between the point light sources and the photodetection elements; and a detection circuit electrically coupled to the photodetection elements. Each point light source corresponds to at least one of the photodetection elements. In a light amount setting mode, the point light sources are lit up at different light amounts; the photodetection elements output sensor values corresponding to the different light amounts; the sensor values that are detected are compared with a preset target sensor value; and light amounts for detection of the point light sources are set. In a detection mode, the point light sources are lit up at the set light amounts for detection; and the photodetection elements output sensor values corresponding to the light amounts for detection.Type: ApplicationFiled: March 13, 2024Publication date: October 3, 2024Inventors: Kaoru ITO, Akihiko FUJISAWA, Daichi ABE

Publication number: 20240317220Abstract: A vehicle control system generates a target trajectory and controls a vehicle to follow the target trajectory. Blind spot information indicates a blind spot region present in front of the vehicle. Under assumption that a first object appears at a first position in front of the vehicle, decelerating the vehicle with a first deceleration cannot avoid a collision between the first object and the vehicle. A deceleration map, which is prepared in advance, indicates at least a collision region consisting of the first position. The vehicle control system recognizes, based on the deceleration map, the collision region under assumption that the vehicle reaches a future position on the target trajectory. When the collision region and the blind spot region overlap each other, the vehicle control system modifies the target trajectory so that the collision region and the blind spot region do not overlap each other.Type: ApplicationFiled: March 5, 2024Publication date: September 26, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Sadayuki ABE, Yusuke HAYASHI, Daichi HOTTA, Taichi KAWANAI

Publication number: 20240253650Abstract: A vehicle control system for controlling a vehicle is configured to perform automated driving by switching between a plurality of automated driving modes. The plurality of automated driving modes include: a first automated driving mode that does not require a driving operation by a human; and a second automated driving mode that requests an operation or monitoring by a human as necessary. In the first automated driving mode, the vehicle control system determines that there is human intervention when an operation state of an operating member operable by a human satisfies a first condition. In the second automated driving mode, the vehicle control system determines that there is human intervention when the operation state of the operating member satisfies a second condition. The first condition is less likely to be satisfied than the second condition.Type: ApplicationFiled: December 7, 2023Publication date: August 1, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke HAYASHI, Taichi KAWANAI, Daichi HOTTA, Sadayuki ABE

Patent number: 11762496Abstract: A technology which can improve the accuracy of touch detection is proposed. A display device includes: a touch panel including plural drive electrodes and plural detection electrodes; plural peripheral wirings; and plural switching elements each of which is disposed between a detection electrode and the corresponding peripheral wiring and that is connected to the detection electrode and the corresponding peripheral electrode. The touch panel executes detection by means of a mutual detection scheme using the plural drive electrodes and the plural detection electrodes. In a condition in which a predefined voltage is applied to the peripheral wirings when the plural switching elements are in an off-state, the voltages of the drive electrodes are changed, and subsequently a condition in which the changes of the voltages of the drive electrodes can be detected from the peripheral wirings is set, and the switching elements are turned from off to on.Type: GrantFiled: February 17, 2022Date of Patent: September 19, 2023Assignee: Japan Display Inc.Inventors: Akihiko Fujisawa, Daichi Abe, Kaoru Ito
