The electronic control unit is configured to maintain a value of the generated voltage in the power generation control to be constant during an upshift gear change when the upshift gear change control of a transmission is executed while the lock-up clutch control is executed during deceleration of the vehicle. The electronic control unit is configured to increase the value in the power generation control during the downshift control to the value of the target generated voltage at a first specified rate when a downshift gear change of the transmission is executed while the lock-up clutch control is executed during the deceleration.Type: ApplicationFiled: June 1, 2017Publication date: December 21, 2017Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keigo MATSUBARA, Chikashi OHTA

Publication number: 20170361834Abstract: A vehicle includes friction brakes, an axle, and a controller. The axle has an electronic limited-slip differential that includes a variable torque capacity lockup clutch. The controller is programmed to, in response to a difference between desired and actual yaw rates exceeding a first threshold, increase the torque of the lockup clutch to decrease the difference between the desired and actual yaw rates. The controller is further programmed to, in response the difference between desired and actual yaw rates exceeding a second threshold that is greater than the first threshold, increase the torque of the friction brakes to decrease the difference between the desired and actual yaw rates.Type: ApplicationFiled: June 21, 2016Publication date: December 21, 2017Inventors: Anthony PASKUS, Neil HURST, Marshall Erin BATES, Ashok E. RODRIGUES, Andrew MONTICELLO, Michael Edward BREWER

Publication number: 20170361835Abstract: Devices and methods in an autonomous parking controller for a vehicle are disclosed. When the vehicle is located at a parking location, the method determines whether the parking location includes a parking restriction. When the parking location includes the parking restriction, the example method compares the parking restriction with at least one restriction threshold. When the parking restriction compares unfavorably with the at least one restriction threshold, the example method, while at the parking location, monitors for a change in at least one of a plurality of ambient conditions relative to the vehicle. When the example method detects the change, the vehicle is autonomously relocated to another location to alleviate the active obstruction.Type: ApplicationFiled: June 17, 2016Publication date: December 21, 2017Inventors: Christopher T. Tarte, Danil V. Prokhorov

Publication number: 20170361836Abstract: A vehicle hitch detection system is provided. The vehicle hitch detection system includes a camera arranged to capture images of a vehicle hitch and a controller processing the images to detect a powered hitch ornament connected to the hitch based on the processed images when an electrical hitch connection is detected. The controller may further control a driver assistance system based on the detected hitch ornament to enable or disable the system.Type: ApplicationFiled: June 20, 2016Publication date: December 21, 2017Inventor: Erick Michael Lavoie

Publication number: 20170361837Abstract: An electronic control unit of a hybrid vehicle is configured to determine whether or not parking operation of the hybrid vehicle is being performed. The electronic control unit is configured to control the engine and the rotary electric machine such that starting the engine when the parking operation of the hybrid vehicle is being performed is harder than starting the engine when the parking operation of the hybrid vehicle is not being performed.Type: ApplicationFiled: June 16, 2017Publication date: December 21, 2017Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Keisuke MORISAKI
