Patent number: 10967831Abstract: A seatbelt retractor device includes a pre-tensioner section, and a force limiter section that can change a magnitude of a load at which to start reducing tension of the retracted seatbelt. A seatbelt control ECU activates the pre-tensioner section when a deceleration G detected by a floor sensor exceeds a first threshold, and acquires a collision velocity from a radar device and sets a second threshold value to a lower value the greater the collision velocity. The seatbelt control ECU controls the starting load for tension reduction by the force limiter section to be a high load when the deceleration G has exceeded the second threshold within a determination time period after activation of the pre-tensioner section, and controls the starting load for tension reduction to be a low load when which the deceleration G has not exceeded the second threshold within the determination time period.Type: GrantFiled: January 25, 2019Date of Patent: April 6, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takashi Fujinami, Yusuke Mase

Patent number: 10967839Abstract: A vehicle control system of a vehicle includes a trailer brake control electronic control unit (ECU), which in turn includes a trailer brake output circuit. The trailer brake control ECU is configured to receive an electronic parking brake (EPB) state flag and a vehicle acceleration message. The dynamic EPB state flag indicates one of an ON state and an OFF state of a dynamic EPB, and the vehicle acceleration message indicates an acceleration of the vehicle. The trailer brake control ECU outputs, via the trailer brake output circuit, a trailer brake signal based on the acceleration of the vehicle indicated by the received vehicle acceleration message in response to determining that the received dynamic EPB state flag indicates the ON state.Type: GrantFiled: January 31, 2019Date of Patent: April 6, 2021Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Adam VanAntwerp, Corey Zwegers, Stephen Robertson, Takayuki Goto, Yuichi Shimizu

Patent number: 10967735Abstract: A control device is to be applied to a four-wheel drive vehicle including a first coupling device interposed between a rear-wheel final gear device and a rear left wheel axle and a second coupling device interposed between the rear-wheel final gear device and a rear right wheel axle. The control device includes a controller changes a coupling torque of the first coupling device and a coupling torque of the second coupling device independently of each other. The controller estimates, when the vehicle is accelerating, a vehicle body speed of the vehicle under a state in which the coupling torque of any one of the first coupling device and the second coupling device is set to a value larger than zero and the coupling torque of another one thereof is set to zero. Thereby, the control device can accurately estimate the vehicle body speed when the vehicle is traveling while accelerating.Type: GrantFiled: September 19, 2018Date of Patent: April 6, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Ryochi Watanabe

Patent number: 10967726Abstract: A controller for a hybrid system is provided. A clutch is disposed between a crankshaft and a drive shaft of an electric motor. An engine-side rotating body rotates integrally with the crankshaft. A motor-side rotating body rotates integrally with the drive shaft. The controller performs balance control. In the balance control, the controller causes the engine-side rotating body and the motor-side rotating body to rotate relative to each other by bringing the clutch into the slipping state. Thereafter, the controller switches the clutch to the engaged state such that the position of the center of gravity of the engine-side rotating body and the position of the center of gravity of the motor-side rotating body are farther from each other in the circumferential direction than before bringing the clutch into the slipping state.Type: GrantFiled: January 17, 2020Date of Patent: April 6, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Tomokazu Inagawa
