Patent number: 8909386Abstract: In a vehicle control system, an index used to set a running characteristic of a vehicle is obtained based on a running condition of the vehicle. A change of the index that makes behavior of the vehicle crisper is more likely to occur than a change of the index that makes the behavior of the vehicle milder. When it is determined that the vehicle is in a turning condition, the change of the index or a change of the miming characteristic based on the index is less likely to occur than when it is determined that the vehicle is not in the turning condition.Type: GrantFiled: August 17, 2010Date of Patent: December 9, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Keisuke Takeuchi, Toshio Tanahashi, Hiroyuki Hanamura, Shin Noumura, Ken Koibuchi, Kaiji Itabashi, Yoji Takanami, Norimi Asahara

Patent number: 8775040Abstract: A vehicle control system obtains an index indicating a running condition of a vehicle on the basis of a vehicle parameter indicating a motion of the vehicle and then sets a running characteristic of the vehicle in accordance with the index. The vehicle control system includes a noise reduction unit that is configured to obtain the index on the basis of the vehicle parameter of which a fluctuating component that fluctuates because of a driver's driving operation or the influence of a running road surface.Type: GrantFiled: August 17, 2010Date of Patent: July 8, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shin Noumura, Ken Koibuchi, Keisuke Takeuchi, Toshio Tanahashi, Hiroyuki Hanamura, Yoji Takanami, Norimi Asahara, Kaiji Itabashi

Patent number: 8596162Abstract: An object of the present invention is to improve the easiness of steadily maintaining the magnitude of treading on a foot-operated operating element while mitigating a feeling of treading on a wall at the time of start of treading on the operating element. A pedal-operated operation device includes a pedal arm, a support housing, a spring for urging the pedal arm in a direction of return, a first shim and a second shim. A frictional engagement portion of the second shim is higher in maximum static friction force than a frictional engagement portion of the first shim. The second shim has a region in which the elastic modulus of the second elastic deformation portion is lower than that of the first shim, in terms of elastic deformation at the time when the pedal arm moves relative to the support housing.Type: GrantFiled: June 12, 2008Date of Patent: December 3, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kazuo Nozu, Norihiro Nishiumi, Hiroyuki Hanamura, Toshio Tanahashi

Patent number: 8521338Abstract: A vehicle control system capable of improving drivability by reflecting driving environment and driving preference accurately on driving characteristics. The vehicle control system is configured to change an index for setting driving characteristics of the vehicle. When accelerations Gx and Gy are changed, a sportiness index is changed in a different manner depending on a detail of an operation for changing accelerations Gx and Gy executed by a driver, thereby reflecting the driving preference of the driver appearing on the operation can be reflected on sportiness of the vehicle.Type: GrantFiled: August 18, 2010Date of Patent: August 27, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Keisuke Takeuchi, Toshio Tanahashi, Ken Koibuchi, Kaiji Itabashi, Shin Noumura, Hiroyuki Hanamura, Yoji Takanami, Norimi Asahara

Patent number: 8428845Abstract: Provided is a vehicle control apparatus which can prevent drivability from being deteriorated. The vehicle control apparatus comprises an ECU adapted to determine whether or not a brake is “off” or the state of the hysteresis width of an accelerator opening degree exceeding a predetermined hysteresis width is continued for a predetermined period of time during the execution of an engine torque reduction control process. When the ECU determines that the brake is “off” or that the state of the hysteresis width of an accelerator opening degree exceeding a predetermined hysteresis width is continued for a predetermined period of time, the ECU performs an engine torque restoration process of the engine. Therefore, the vehicle control apparatus can allow the continued execution and non-execution of the reduction control to be switched therebetween in accordance with the driver's travel intention, thereby making it possible to prevent the drivability from being deteriorated.Type: GrantFiled: December 28, 2009Date of Patent: April 23, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tsutomu Miyazaki, Toshiya Oishi, Masashi Takagi, Michihito Shimada, Yuki Minase, Kenichi Okaya, Hiroyuki Hanamura

Publication number: 20120259524Abstract: For providing a vehicle control apparatus which can prevent the deterioration of the drivability, the ECU (100) of the vehicle control apparatus according to the present invention can determine the speed reduction of the vehicle (10) at the time of the accelerator pedal (212) and the foot brake pedal (213) being depressed together, and can abort the execution of the reduction control due to the control permission condition not being established when the speed reduction is not determined (NO in Step S15), so that the execution or non-execution of the reduction control can be carried out avoiding an unintentional braking of the vehicle, thereby making it possible to prevent the drivability from deteriorating.Type: ApplicationFiled: December 28, 2009Publication date: October 11, 2012Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tsutomu Miyazaki, Toshiya Oishi, Masashi Takagi, Michihito Shimada, Yuki Minase, Kenichi Okaya, Hiroyuki Hanamura
