Patent number: 8676461Abstract: A control apparatus controls acceleration of a vehicle provided with a motive power generation apparatus and brake apparatuses. For the control, the control apparatus comprises calculation and actuating blocks. The calculation block calculates torque to be requested, based on a difference between an actual value of the acceleration and a target value thereof and a gain for feedback controlling the actual value of the acceleration to the target value thereof. The gain is differentiated in value between in a first case in which the brake apparatuses are used for the feedback control and a second case in which the brake apparatuses are not used for the feedback control. The actuating block actuates the motive power generation apparatus and the brake apparatuses based on the calculated torque. The value of the gain in the first case is made larger than the value of the gain in the second case.Type: GrantFiled: August 7, 2008Date of Patent: March 18, 2014Assignees: Denso Corporation, Advics Co., Ltd.Inventors: Yasuhiro Nakai, Hajime Kumabe, Shotaro Fukuda, Satoshi Niwa, Hiroyuki Kodama, Kazunori Kadowaki, Shintaro Osaki

Patent number: 8401757Abstract: A running control apparatus calculates a target driving or braking torque in a calculating block to control the vehicle driven or braked by this torque at a target speed against a running resistance changed with running circumstances of the vehicle. In a control block, when a driver-required braking torque based on the braking operation of the driver is smaller than the target braking torque, the running control for the vehicle is performed to brake the vehicle by the target braking torque. When the driver-required braking torque becomes higher than the target braking torque, the running control is stopped, and the driver manually brakes the vehicle by the driver-required braking torque. When the driver-required braking torque is decreased to be lower than the target braking torque or a predetermined braking torque corresponding to the release of the braking operation, the running control is restarted.Type: GrantFiled: November 30, 2009Date of Patent: March 19, 2013Assignees: DENSO CORPORATION, Advics Co., Ltd.Inventors: Mitsuhiro Tokimasa, Hajime Kumabe, Satoshi Niwa, Shotaro Fukuda, Masayoshi Takeda, Shintaro Osaki

Patent number: 8364368Abstract: A reliability for a power-train feed-forward torque may be decreased when a degree of reliability for an estimated braking torque is decreased due to disturbance factors. A power-train feedback torque is corrected based on a degree of reliability for a power-train torque, for which a reliability for a braking condition is taken into account. In a similar manner, a brake feedback torque is corrected based on a degree of reliability for a braking torque, for which a reliability for a power-train condition is taken into account. Accordingly, it is possible to compensate the decrease of reliability for the power-train feed-forward torque or brake feed-forward torque by the correction for the power-train feedback torque or the brake feedback torque.Type: GrantFiled: December 22, 2009Date of Patent: January 29, 2013Assignees: Advics Co., Ltd., DENSO CORPORATIONInventors: Masatoshi Hanzawa, Masayoshi Takeda, Hiroyuki Kodama, Hajime Kumabe

Patent number: 8332117Abstract: An object of the invention is to provide an acceleration control apparatus, according to which accuracy for feed-forward torque may not be decreased even when a calculating accuracy for an estimated-slope torque would be decreased. Reliability of estimated slope is calculated and feedback torque is corrected, in such a manner that a gain for a feedback control portion is increased when the reliability of the estimated slope becomes lower. It is, therefore, possible to compensate a possible decrease of the accuracy of the feed-forward torque by correcting the feedback torque in accordance with the reliability of the estimated slope.Type: GrantFiled: June 29, 2010Date of Patent: December 11, 2012Assignees: Advics Co., Ltd., DENSO CORPORATIONInventors: Masatoshi Hanzawa, Masayoshi Takeda, Hiroyuki Kodama, Hajime Kumabe

Patent number: 8292784Abstract: In a vehicle control device, a brake feedback control unit calculates a brake feedback torque Tfb-BK using a PID control model when a current state is a brake feedback use state. The brake feedback control unit stops the calculation of the brake feedback torque Tfb-BK when the current state is a brake feedback limitation state, and stores as an output value the brake feedback torque Tfb-BK that is output at a brake limitation start timing. At a brake limitation release timing, the brake feedback control unit restarts the feedback control using the stored brake feedback torque Tfb-BK as an initial value. The brake mechanism can thereby generate a predetermined brake torque of not more than 0 [N·m] immediately after the brake limitation release timing.Type: GrantFiled: July 14, 2009Date of Patent: October 23, 2012Assignees: DENSO CORPORATION, Advics Co., Ltd.Inventors: Motoaki Umakoshi, Shotaro Fukuda, Hajime Kumabe, Masayoshi Takeda, Yukio Mori

Patent number: 8214124Abstract: 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: GrantFiled: May 27, 2008Date of Patent: July 3, 2012Assignees: Denso Corporation, Advics Co., Ltd.Inventors: Hajime Kumabe, Yasuhiro Nakai, Satoshi Niwa, Shotaro Fukuda, Masayoshi Takeda, Hiroyuki Kodama
