Patent number: 11643057Abstract: Driving support ECU transmits a communication connection request to a help net center HNC when a driver of a vehicle has been determined to be in an abnormal state where the driver loses an ability to drive the vehicle, and when the communication connection to the help net center HNC has been established, the driving support ECU transmits the help signal (the positional information of the vehicle) and decelerates the vehicle at a constant deceleration to make the vehicle stop. On the other hand, when the communication connection to the help net center HNC has not been established, the driving support ECU makes the vehicle travel at a constant speed. Accordingly, it is possible to make the vehicle stop under a situation where the help net center HNC recognizes the vehicle position inside which the driver who has been determined to be in the abnormal state is.Type: GrantFiled: October 12, 2020Date of Patent: May 9, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Hirotada Otake

Patent number: 10377366Abstract: A driver is prevented from carrying out hands-free driving while lane keeping assist control is being carried out, thereby appropriately determining an abnormal state of the driver. When a steering wheel no-operation state continues for a first period or more, a driving support ECU sets a control mode of LKA to a “weaker mode”, thereby decreasing a control amount of the LKA. As a result, an own vehicle swerves within a travel lane, and the driver neglecting the steering wheel operation can be prompted to operate the steering wheel. Further, when the no-driving operation state continues for a second period or more, the driving support ECU establishes determination that the driver is in an abnormal state, returns the LKA to a “normal mode”, and decelerates and stops the own vehicle.Type: GrantFiled: July 12, 2017Date of Patent: August 13, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Hirotada Otake

Patent number: 10351109Abstract: Driving support ECU sets a driver's state to “temporarily abnormal” and decelerates a vehicle when a driver of the vehicle has been first determined to be in an abnormal state where the driver loses an ability to drive the vehicle. Driving support ECU changes the driver's state to “regularly abnormal” in a case when the abnormal state of the driver remains unchanged when a vehicle speed decreases to a set vehicle speed, and at this point, reports to a help net center HNC. With this configuration, a report to the help net center HNC can be made at an appropriate timing.Type: GrantFiled: June 14, 2017Date of Patent: July 16, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Hirotada Otake

Patent number: 10336344Abstract: Driving support ECU determines that a driver is in an abnormal state when a state where a steering amount correlation value which changes when a steering wheel SW of a vehicle is operated does not change continues over more than or equal to an abnormality determination threshold time. When the driver is determined to be in the abnormal state, the ECU decelerates the vehicle, makes a hazard lamp blink and invalidates an acceleration request based on a change in an operation amount of an accelerator pedal. The ECU terminates decelerating of the vehicle and permits the acceleration override when a specific driving operation (an operation that the accelerator pedal changes from an operating state to a non-operating state and then again changes to the operating state within a predetermined threshold time) is determined to have occurred after the driver has been determined to be in the abnormal state.Type: GrantFiled: February 14, 2017Date of Patent: July 2, 2019Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Hirotada Otake
