A down-shift line is defined such that the drive force decreases with increase in accelerator pedal position. Down-shift after up-shift as well as the up-shift after the down-shift are inhibited when both a condition that an amount of change of the accelerator pedal position after last gear shift is larger than a threshold and a condition that an amount of change of the drive force after the last gear shift is larger than the threshold are satisfied.Type: GrantFiled: July 3, 2008Date of Patent: October 30, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Seiji Kuwahara, Masato Kaigawa

Patent number: 8301349Abstract: A control method and system for a vehicle transmission that incorporates gradient road resistance in selecting an appropriate gear ratio for an automatic manual transmission or an automatic transmission are disclosed. The traction resistance of a vehicle is calculated in order to determine the traction force required for maintaining, increasing, or decreasing vehicle speed in response to operator input. Traction resistance may be a function of rolling resistance, air resistance, and the component of the gravitational force acting parallel to the road surface. The change in traction resistance is also determined. The calculated traction resistance and change in traction resistance may advantageously be used to calculate an offset to a shift point motor speed in order to delay or advance a transmission upshift when climbing a grade.Type: GrantFiled: April 3, 2009Date of Patent: October 30, 2012Assignee: ZF Friedrichshafen AGInventor: Ingo-Gerd Sauter

Patent number: 8265840Abstract: A control device for an automatic transmission is disclosed wherein a shift point depending on a variation in vehicle acceleration is modified on a real time basis in accordance with not only a corrected result on a shift point depending on piece-to-piece variations of automatic transmissions, but also actual acceleration for shortening a time required for learning with high precision with no need to be matched. Shift point real-time modifying means is provided for modifying the altered shift point based on a value of a ratio between a value of actual engine-rotation acceleration at an upshift-determining timing during a power-on running and a value of reference engine-rotation acceleration obtained by substituting a value of actual engine-rotation acceleration to a value for a reference running state having no impact on acceleration of a vehicle, and a target maximum engine rotation speed.Type: GrantFiled: October 4, 2007Date of Patent: September 11, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masato Watanabe, Masato Kaigawa, Ichiro Kitaori, Masakazu Owatari

Patent number: 8249774Abstract: A toe angle changing control ECU for controlling a toe angle of wheels of a vehicle. The toe angle changing control ECU includes: a straight traveling state judging section for judging whether or not the vehicle is in a; a memory for storing the toe angle of the wheels while the vehicle is in the straight traveling state; and a toe angle setting section for setting the wheels to the toe angle stored in the memory when the straight traveling state judging section judges that the vehicle is in the straight traveling state. While in the straight traveling state, the wheels are set to a toe angle at which the wheels are substantially parallel to the longitudinal direction of the vehicle, reducing the rolling resistance of the wheels, and improving fuel consumption.Type: GrantFiled: September 21, 2011Date of Patent: August 21, 2012Assignee: Honda Motor Co., Ltd.Inventors: Koichi Suyama, Akiyoshi Kobayashi, Yutaka Horiuchi, Kenji Hattori

Patent number: 8244432Abstract: A road-surface friction-coefficient estimating device compares a rack-thrust-force deviation value with a preliminarily set maximum-value-determination threshold value. If the rack-thrust-force deviation value is above the maximum-value-determination threshold value, the device determines that tires are slipping, and sets a front-wheel friction-circle utilization rate in that state as a road-surface friction coefficient. If the rack-thrust-force deviation value is below the maximum-value-determination threshold value, the device refers to a preliminarily set map to determine a restoring speed at which the road-surface friction coefficient is to be restored to 1.0 based on a vehicle speed and a front-wheel slip angle. While restoring the road-surface friction coefficient at the restoring speed, the device calculates and outputs the road-surface friction coefficient.Type: GrantFiled: April 11, 2008Date of Patent: August 14, 2012Assignee: Fuji Jukogyo Kabushiki KaishaInventors: Masaru Kogure, Koji Matsuno, Takeshi Yoneda

Patent number: 8244420Abstract: If an accelerator pedal is released, when a flag indicates 1, a vehicle travels in a traveling environment reflected operation mode where an engine and two motors are controlled in a manner that a required torque is output to a drive shaft while the engine is operated by the motor. If a vehicle speed is equal to or lower than a threshold at the time or after the flag is changed from 1 to 0, the vehicle travels in a normal operation mode where the engine and two motors are controlled in a manner that the required torque is output to the drive shaft with engine rotation stopped. If the vehicle speed is higher than the threshold when the flag is changed from 1 to 0, the vehicle travels in the traveling environment reflected operation mode until the vehicle speed becomes equal to or lower than the threshold.Type: GrantFiled: May 26, 2009Date of Patent: August 14, 2012Assignees: Toyota Jidosha Kabushiki Kaisha, Aisin AW Co., Ltd.Inventors: Takahiro Shimohira, Ryo Shimizu, Hideki Furuta

Patent number: 8229634Abstract: A method of controlling an automatic transmission of a motor vehicle that is situated in the force flow between a drive motor and an axle drive of a drive axle or a transfer box in which the current road inclination (?FB) is determined. To improve the shifting behavior of the transmission, during a transition between driving on a downhill stretch (2) and on level ground (4), after driving on the downhill stretch (2) and/or after the transition to a thrust operation, a recognition function for determining a downhill run-out (3) is initiated and, when the downhill run-out (3) is recognized, a shift to a higher gear during a thrust operation, i.e., a thrust upshift, is carried out before driving onto level ground (4) and/or before the transition to the traction operation.Type: GrantFiled: September 11, 2008Date of Patent: July 24, 2012Assignee: ZF Friedrichshafen AGInventor: Matthias Winkel

Patent number: 8214125Abstract: A vehicle speed setting of cruise control is changed based on an operation by a driver. At this time, it is determined whether the vehicle is traveling in a passing lane or a traveling lane (S202). If the vehicle is traveling in a passing lane, the speed at which the vehicle speed setting is changed is increased (S206). If a blinker on the passing lane side of the vehicle is on (S205), the speed at which the vehicle speed setting is changed is also increased (S206) even if the vehicle is traveling in the traveling lane.Type: GrantFiled: November 14, 2007Date of Patent: July 3, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventor: Takeshi Nanami

Patent number: 8209103Abstract: The drive control of the invention adopted in a hybrid vehicle specifies an operation line L to give a greater torque in a low rotation speed area of an engine with an increase in vehicle speed and controls the operation of the engine according to the specified operation line L. The engine can thus be driven at a higher-efficiency drive point, while the driving-related background noise effectively masks some abnormal noise or muffled noise, which may be caused by the operation of the engine in a low rotation speed-high torque area. This arrangement desirably prevents the driver and the other passenger from feeling odd and uncomfortable due to the abnormal noise or muffled noise and enhances the energy efficiency of the hybrid vehicle.Type: GrantFiled: July 13, 2006Date of Patent: June 26, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shunsuke Oyama, Yasuhiro Kaya
