Patent number: 9428053Abstract: An electronic control unit performs a reduction control for reducing vehicle drive force when the accelerator and the brake are operated simultaneously. The electronic control unit also varies the amount of decrease in the vehicle drive force during the reduction control and conditions under which the reduction control is implemented depending on the order of the accelerator operation and brake operation resulting in the above-noted simultaneous operation. For example, the amount of decrease in the vehicle drive force is less when the brake is operated first in comparison with when the accelerator is operated first. Thus, it is possible to operate the vehicle drive force in accordance with the intention of the driver.Type: GrantFiled: June 16, 2011Date of Patent: August 30, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masashi Takagi, Hiroshi Shimada, Michihito Shimada, Motonari Obayashi, Shinya Kodama, Akihiro Kida, Akito Oonishi, Takamasa Kitamura

Patent number: 8930100Abstract: A vehicle has a shift mechanism and a position detection device that detects an operation position of the shift mechanism. A transmission is brought to a power transmission state when an operation unit of the shift mechanism is operated to a driving position, and is brought to a power interrupt state when the operation unit is operated to a non-driving position. A driving force limitation process for reducing the driving force of an internal combustion engine is executed when it is determined that the non-driving position has been shifted to the driving position on the basis of the operation position of the operation unit as detected by the position detection device. The driving force limitation process is prohibited when it is determined that the vehicle is traveling and that the operation unit is not operated to any of the operation positions.Type: GrantFiled: December 11, 2012Date of Patent: January 6, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yuki Minase, Masashi Takagi, Motonari Ohbayashi, Hiroshi Shimada, Toshihiro Takagi

Patent number: 8751120Abstract: A system includes: a shift mechanism; and a position detecting device detecting an operating position of the shift mechanism on the basis of an output signal of a sensor attached to the shift mechanism. An execution mode of a driving force limiting process that limits driving force is set on the basis of the operating position that is detected by the position detecting device. The driving force limiting process is executed on the basis of the execution mode of the driving force limiting process and a vehicle operation state. When it is determined that there is an abnormality in the position detecting device in a state that the driving force limiting process is not executed, setting the execution mode on the basis of the operating position of the shift mechanism is prohibited, and execution of the driving force limiting process is allowed on the basis of the vehicle operation state.Type: GrantFiled: December 12, 2012Date of Patent: June 10, 2014Assignee: Toyota Jidosha KabushikiInventors: Yuki Minase, Masashi Takagi, Motonari Ohbayashi, Hiroshi Shimada, Toshihiro Takagi

Publication number: 20140136084Abstract: A brake override system (BOS) (1) prioritizes braking when both an accelerator and a brake are operated simultaneously by reducing the required accelerator operation amount value that is used to control drive force so that it is lower than the actual accelerator operation amount. The BOS (1) thus achieves a balance between hill-start performance after operation by the BOS (1) is cancelled and stopping performance during operation of the BOS (1) by increasing the required accelerator operation amount value at the time at which the return of the required accelerator operation amount value to the actual accelerator operation amount is initiated when the simultaneous operation of the accelerator and the brake ends.Type: ApplicationFiled: July 1, 2011Publication date: May 15, 2014Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masashi Takagi, Shinya Kodama, Akihiro Kida, Motonari Obayashi, Hiroshi Shimada, Akito Oonishi, Takamasa Kitamura, Michihito Shimada
