Publication number: 20140244115Abstract: A driving support apparatus includes an output unit installed in a steering wheel that outputs steer information about a rotation operation of the steering wheel to the driver through the output unit. By providing the driver with steer information from the output unit in the steering wheel, the driver may recognize the contents of the output of the steer information. Further, since the steer information has a high priority for the driver due to its direct relevance to movement and a travel direction of the vehicle, providing such high priority steer information in an easily-recognizable manner improves driver awareness or readiness to recognize lower-priority information. Thus, information overload by the driver caused by information from various driving support techniques is prevented.Type: ApplicationFiled: February 12, 2014Publication date: August 28, 2014Applicant: DENSO CORPORATIONInventors: Norio SANMA, Sei IGUCHI

Patent number: 8704652Abstract: An information providing apparatus includes a tactile information provider and a controller. The tactile information provider is arranged within a rim portion of a steering wheel of a vehicle and provides a tactile sense to a driver. The controller controls the tactile information provider to provide support information to the driver. The support information is defined as information that supports a driving of the vehicle. The tactile information provider includes a trench arranged in a circumferential direction of the rim portion, a ring-shaped ring portion, and a driving portion. The ring portion is rotatably arranged in the trench and has an exposed surface such that the exposed surface contacts with at least one hand of the driver. The driving portion is controlled by the controller to drive the ring potion rotate in the circumferential direction to provide the support information to the driver.Type: GrantFiled: October 29, 2012Date of Patent: April 22, 2014Assignees: DENSO CORPORATION, Nippon Soken, Inc.Inventors: Norio Sanma, Sei Iguchi, Daisuke Sugiura
