Publication number: 20230380741Abstract: A driver state determination apparatus detects decline of the physical function of a driver and confirms an abnormal state before the driver becomes unable to drive. A vibration apparatus vibrates a steering wheel; a vibration detector detects vibration of the steering wheel; a steering angle sensor detects a steering angle of the steering wheel; and a controller controls the vibration apparatus. The controller provides vibration at a predetermined excitation frequency to the steering wheel by the vibration apparatus, calculates a steering torque level at the excitation frequency based on the vibration detected by the vibration detector, and determines that the driver is in an abnormal state when a correlation coefficient between a time variation of a steering torque level while the vibration is being provided and a time variation of a steering angle while the vibration is being provided is equal to or more than a predetermined value.Type: ApplicationFiled: March 24, 2023Publication date: November 30, 2023Applicant: MAZDA MOTOR CORPORATIONInventors: Akira Kaino, Yoshitaka Fujihara, Yoko Hoshino

Patent number: 11745752Abstract: A vehicle control system can have an in-vehicle camera that monitors a state of the driver; a center display and a meter device that notify the occupant of information; and a controller that executes automatic stop control in the case where the driver abnormality is determined. The controller can perform: a first operation to decelerate the vehicle to a specified speed when the abnormality is determined; a second operation to further decelerate and stop the vehicle after the first operation; a third operation to change a lane of the vehicle between the first operation and the second operation; and a fourth operation to move the vehicle to a road shoulder between the first operation and the second operation. The controller can notify the operation performed, and notify of a stop of the operation in the case where the operation performed is stopped.Type: GrantFiled: March 17, 2021Date of Patent: September 5, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Akira Kaino, Yoshitaka Fujihara
