Patent number: 9435275Abstract: 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: GrantFiled: July 1, 2011Date of Patent: September 6, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masashi Takagi, Shinya Kodama, Akihiro Kida, Motonari Obayashi, Hiroshi Shimada, Akito Oonishi, Takamasa Kitamura, Michihito Shimada

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: 9222421Abstract: An electronic control unit (1) stops output suppression control for an engine (6) at the time of simultaneous depression of an accelerator pedal (2) and a brake pedal (4) when the depression of the brake pedal (4) is erroneously detected due to an ON-failure of a stop lamp switch (5) even if the brake pedal is not depressed.Type: GrantFiled: April 21, 2011Date of Patent: December 29, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shinya Kodama, Masashi Takagi, Michihito Shimada, Akihiro Kida, Motonari Obayashi, Hiroshi Shimada, Akito Oonishi, Takamasa Kitamura

Patent number: 9108626Abstract: When simultaneous depression of an accelerator pedal (2) and a brake pedal (4) is detected, an electronic control unit (1) inhibits a downshift of an automatic transmission (11) and performs output suppression control for an engine (6), thereby making it possible to suppress the increase of vehicle drive force caused by the downshift and maintain a constant vehicle deceleration rate by an easier operation.Type: GrantFiled: April 21, 2011Date of Patent: August 18, 2015Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Akihiro Kida, Masashi Takagi, Michihito Shimada, Shinya Kodama, Motonari Obayashi, Hiroshi Shimada, Takamasa Kitamura, Akito Oonishi

Patent number: 7035724Abstract: A driving force generated by an engine is transmitted to driving wheels (not shown) via an automatic transmission. The engine is provided with an electronically controlled throttle body and the like. An E-ECU performs cooperative control when necessary, so that an output of the engine is obtained in accordance with a load applied thereto. On the other hand, the automatic transmission is provided with a torque converter. Even in the case where the aforementioned predetermined condition has been fulfilled in a T-ECU, if the E-ECU detects a deterioration in performance of the electronically controlled throttle body or the like, the performance of neutral control is prohibited.Type: GrantFiled: August 19, 2003Date of Patent: April 25, 2006Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takeshi Tokuda, Akito Oonishi

Patent number: 4466413Abstract: The present invention relates to a fuel cut system for an electronic control system of an engine. When the deceleration of engine rotation is large during fuel cut, the fuel cut is interrupted at the rotational speed higher than when the deceleration is small, and thereby the engine stop caused by the fuel cut during racing period or the like is prevented.Type: GrantFiled: June 24, 1982Date of Patent: August 21, 1984Assignee: Toyota Jidosha Kogyo Kabushiki KaishaInventors: Akito Oonishi, Haruo Watanabe
