The control apparatus and control method determine whether the vehicle is in a high load state; determine whether engine braking force from the internal combustion engine is required; calculate differential braking force which is the difference between engine braking force generated when running in a gear selected according to the manual operation and engine braking force generated when running in a gear selected according to the running state; and control the automatic transmission to execute an upshift and perform control to generate the calculated differential braking force when it is determined that i) the vehicle is in the high load state and ii) the engine braking force is required, while the automatic transmission is in the manual shift mode. | 04-02-2009 |
20090292430 | SHIFT CONTROLLER OF VEHICLE AUTOMATIC TRANSMISSION - A shift controller includes: a shift control unit automatically shifting gears of an automatic transmission using a basic shift line map; a shift line map switching control unit switching from the basic shift line map to a high fluid temperature shift line map set on a lower vehicle speed side when a hydraulic fluid temperature in the automatic transmission is higher than a predetermined value; and a low power state determination unit determining whether a vehicle is in a low power state in which a required power related value used for gear shift determination is lower than a predetermined determination value. The shift line map switching control unit switches from the high fluid temperature shift line map back to the basic shift line map when the hydraulic fluid temperature is lower than the predetermined value and the vehicle is in the low power state. | 11-26-2009 |
20100010716 | CONTROL DEVICE FOR VEHICULAR AUTOMATIC TRANSMISSION - A control device for an automatic transmission | 01-14-2010 |
20100094516 | VEHICLE CONTROL DEVICE AND VEHICLE CONTROL METHOD - A vehicle control device and a vehicle control method for executing the following control are provided. When a driving mode is input, a CPU of an ECU outputs an instruction for shifting a power transfer mechanism in accordance with the input driving mode, and controls a power control mechanism in accordance with a stored driving mode. When it is determined that shifting of the power transfer mechanism has been completed, the CPU switches the characteristic of the power control mechanism in accordance with the input driving mode. On the other hand, when it is determined that a predetermined period of time has elapsed without completing the shifting from when the instruction for shifting the power transfer mechanism is issued, the CPU maintains the characteristic of the power control mechanism at a characteristic corresponding to the stored driving mode. | 04-15-2010 |
20100262345 | CONTROL APPARATUS FOR MULTI-SPEED AUTOMATIC TRANSMISSION - A control apparatus for a multi-speed automatic transmission which is equipped with a manual shift mode that allows a speed step to be shifted up or down manually by an operation of a driver of the vehicle is provided. The control apparatus permits a downshift to be manually performed, provided that during the manual mode, one of vehicle speed, engine rotation speed, and turbine rotation speed of the multi-speed automatic transmission is less than or equal to a downshift permission criterion value that is set according to the speed step achieved by the downshift. The control apparatus corrects the downshift permission criterion value by a speed-value-increasing correction amount that is computed according to the situation of travel of the vehicle. The control apparatus includes a speed-value-increasing correction amount computation portion that computes the speed-value-increasing correction amount separately for each of numbers of steps over which downshifts occur. | 10-14-2010 |
20100305823 | AUTOMATIC TRANSMISSION CONTROL APPARATUS, CONTROL METHOD, PROGRAM FOR REALIZING THAT METHOD, AND RECORDING MEDIUM ON WHICH THAT PROGRAM IS RECORDED - An ECU controls an automatic transmission that can be manually shifted. The ECU executes a program that includes i) the step of, when there are a plurality of allowed gears that are allowed at the time of a downshift operation (i.e., YES in S | 12-02-2010 |
20140214288 | VEHICULAR CONTROL APPARATUS - A control apparatus for controlling a vehicle having an automatic transmission arranged to transmit a vehicle drive force from a drive power source of the vehicle to drive wheels of the vehicle, such that a shift-down operation of the automatic transmission is performed as a result of a kick-down operation, the control apparatus includes a shift-down operation permitting/inhibiting portion configured to restrict the shift-down operation of the automatic transmission as a result of the kick-down operation, if a running speed of the vehicle upon detection of the kick-down operation is lower than a lower limit predetermined for a presently established gear positions or speed ratio of the automatic transmission. | 07-31-2014 |

20100292899 | AUTOMATIC TRANSMISSION CONTROL APPARATUS AND METHOD - When an automatic transmission is in a manual mode, a transmission ECU calculates a speed sftrng manually requested by the driver and a speed sftrngmap set by a shift map and then performs a shift prohibition procedure. In this procedure, if the engine coolant temperature is equal to or lower than a predetermined coolant temperature or the AT fluid temperature is equal to or lower than a predetermined fluid temperature, a prohibition, determination flag xthlow is set to “on”, and if the engine coolant temperature is higher than the predetermined coolant temperature and the AT fluid temperature is higher than the predetermined fluid temperature, the prohibition determination flag xthlow is set to “off”. When the prohibitions determination flag xthlow is “on”, the speed sftrngmap is set as the upper limit of the speed sftrng. | 11-18-2010 |
20120059561 | FUEL-SAVING DRIVE RECOMMENDATION SYSTEM AND FUEL-SAVING DRIVE RECOMMENDATION METHOD - A fuel-saving drive recommendation system is mounted on a vehicle that includes a step-gear automatic transmission of which a gear is shifted in response to a gear instruction signal. The fuel-saving drive recommendation system calculates a required driving force based on an amount by which an output operating component is operated by a driver and a gear of the automatic transmission, makes determination for fuel-saving drive for the vehicle based on the required driving force and notifies the determination result. The fuel-saving drive recommendation system calculates a required driving force for performing output control on an engine and a required driving force for determining whether it is a fuel-saving drive state. A determination gear signal different from the gear instruction signal is used when the determination required driving force is calculated, and is changed to coincide with the gear instruction signal that has been changed. | 03-08-2012 |
