Publication number: 20090062068Abstract: An apparatus controls automatic travel of a vehicle equipped with a motive power generator. In the apparatus, information indicating a road surface on which a vehicle is present currently is acquired. It is determined whether or not a command for shifting the vehicle from its stopped state to its traveling state is issued. When the command is issued, automatic shift of the vehicle is made from its stopped state to its traveling state by controlling drive of the motive power generator based on the acquired information. It is further determined whether or not, of a component of gravity applied to the vehicle, there is a force component applied in a direction opposite to a travel direction of the vehicle. When there is the force component, the operation applied to the motive power generator is continued even if the brake pedal is pressed by the driver.Type: ApplicationFiled: August 27, 2008Publication date: March 5, 2009Applicants: DENSO CORPORATION, ADVICS CO., LTD.Inventors: Yasuhiro NAKAI, Masayoshi TAKEDA, Kazunori KADOWAKI

Publication number: 20090048755Abstract: A vehicle speed control device calculates a desired axle torque for maintaining a speed of a vehicle to a set speed, and conducts cruise control. Specifically, the vehicle speed control device calculates a drive force including a feedforward component corresponding to the set speed and a travel resistance against the travel of the vehicle, and a feedback component corresponding to a deviation of the set speed from the actual speed of the vehicle as a desired axle torque. The vehicle speed control device interrupts the cruise control when a requested drive axle torque requested by an accelerator operation during the cruise control exceeds the desired axle torque, and restarts the cruise control when the requested drive axle torque becomes lower than the desired axle torque.Type: ApplicationFiled: July 9, 2008Publication date: February 19, 2009Applicants: DENSO CORPORATION, Advics Co., Ltd.Inventors: Mitsuhiro Tokimasa, Hajime Kumabe, Syotarou Fukuda, Yasuhiro Nakai, Satoshi Niwa, Hiroyuki Kodama, Masayoshi Takeda, Shintaro Osaki, Kazunori Kadowaki

Publication number: 20090043473Abstract: An apparatus is provided to estimate a gradient of a road surface on which a vehicle travels. The apparatus comprises acquisition, estimation, and compensation members. The acquisition member acquires at least one of acceleration of the vehicle calculated on changes in a travel speed of the vehicle and acceleration sensed from a force applied to the vehicle. The estimation means estimates the gradient of the road surface based on the acquired acceleration. The compensation member compensates the acquired acceleration in terms of influence of noise superposed on the acceleration, depending on an operational condition of the vehicle. The compensated acceleration is used by the estimation. The compensation is carried out by cutting off the noise by a filter, for example.Type: ApplicationFiled: August 8, 2008Publication date: February 12, 2009Applicant: DENSO CORPORATIONInventors: Yasuhiro NAKAI, Hajime KUMABE, Shotaro FUKUDA, Satoshi NIWA, Masayoshi TAKEDA, Yukio MORI

Publication number: 20090024354Abstract: An estimated gradient value of a road is calculated based on a vehicle acceleration “A” and a time varying portion “A?” of a wheel speed. In a case that an acceleration corresponding value “Ggrad0” for the estimated gradient value is not regarded as indicating an exact figure, due to influences of disturbances, the acceleration corresponding value “Ggrad0” is corrected by a limiting value for rate-of-change with regard to the road gradient depending on respective vehicle speed, and by a limiting value for the road gradient. As a result, the acceleration corresponding value “Ggrad” for the estimated gradient value can be more exactly obtained.Type: ApplicationFiled: July 18, 2008Publication date: January 22, 2009Inventors: Shintaro Osaki, Hiroyuki Kodama, Masayoshi Takeda, Kazunori Kadowaki, Hajime Kumabe, Yasuhiro Nakai, Satoshi Niwa, Syotarou Fukuda

Publication number: 20090005945Abstract: A vehicle speed control system starts an automatic decelerating operation with a maximum permissible decelerating physical amount “Gmax”, when an electronic control unit determines that a necessary decelerating physical amount for decreasing a vehicle speed “v” to a target vehicle speed “vt” at a curve starting point becomes larger than the maximum permissible decelerating physical amount “Gmax”. The vehicle speed control system terminates the automatic decelerating operation, when required decelerating physical amount by a braking operation during the automatic decelerating operation becomes larger than an actual control decelerating physical amount for the automatic decelerating operation.Type: ApplicationFiled: June 25, 2008Publication date: January 1, 2009Inventors: Masayoshi Takeda, Kazunori Kadowaki, Shintaro Osaki, Syotarou Fukuda, Yasuhiro Nakai, Satoshi Niwa, Hajime Kumabe

Publication number: 20080300766Abstract: In a cruise control system for a vehicle, a cruise ECU calculates a cornering resistance applied to the vehicle based upon a steering angle, when a vehicle turns. The cruise ECU calculates a speed reduction amount as a correction vehicle speed based upon the cornering resistance. The cruise ECU subtracts the correction vehicle speed from a set vehicle speed to set a target vehicle speed so that the vehicle speed becomes lower as the cornering resistance is larger. The cruise ECU controls the vehicle speed to be within a permissible speed range of the target vehicle speed.Type: ApplicationFiled: May 27, 2008Publication date: December 4, 2008Applicants: DENSO CORPORATION, Advics Co., Ltd.Inventors: Hajime Kumabe, Yasuhiro Nakai, Satoshi Niwa, Shotaro Fukuda, Masayoshi Takeda, Hiroyuki Kodama

Publication number: 20070010929Abstract: In order to ensure that traction control is not initiated when an engine stalling tendency exists, no engine stalling tendency is set as a condition for initiating traction control. Furthermore, in order to ensure that an accurate determination of the engine stalling tendency can be made after the initiation of traction control, an engine speed threshold value used to determine whether the engine stalling tendency exists is changed in accordance with a vehicle status. Thus, the engine stalling tendency can be more accurately determined in comparison to when the engine speed threshold value is set as a constant value (a predetermined speed). Accordingly, it is possible to prevent frequent prohibition of traction control even when the possibility of engine stalling is low.Type: ApplicationFiled: June 8, 2006Publication date: January 11, 2007Inventors: Masayoshi Takeda, Kazunori Kadowaki, Shigeru Saito
