A control apparatus for a vehicular automatic transmission includes a control portion that executes a neutral control in which the control portion places the automatic transmission in a neutral state by reducing an application load on a frictional apply device inside the automatic transmission when the vehicle is stopped. The control portion ends the neutral control when a torque transmitted to the frictional apply device has been continually equal to, or greater than, a predetermined value for a consecutive predetermined of time. As a result, by considering the torque transmitted to the frictional apply device in addition to the continuation time of the neutral control, it is possible to more precisely grasp the state of the frictional apply device. In other words, it is possible to execute, as quickly as possible, neutral control for an extended period of time while ensuring durability of the frictional apply device.

Control apparatus and method for vehicular automatic transmission

An apparatus for controlling an automotive vehicle including a target-drive-force setting portion operable to determine a target vehicle drive force, such that the determined target vehicle drive force permits a smooth change of an actual vehicle drive force with a change of the operating amount of the vehicle accelerating member, irrespective of a shifting action of the transmission, a first controlling portion having a relatively high operating response and operable to effect a transient control of a torque of the drive power source, and a second controlling portion having lower operating response than the first controlling portion but is capable of continuously controlling the torque of the drive power source, the second controlling portion being operable to effect a continuous control of the torque of the drive power source following the transient control by the first controlling portion, so that the actual vehicle drive force coincides with said target vehicle drive force after the shifting action of the transmission.

Vehicle control apparatus

A start control device is provided for a vehicle that is subjected to neutral control for releasing a coupling element of an automatic transmission when the vehicle is stopped with predetermined conditions satisfied while the automatic transmission is in a forward drive position. The start control device detects a braking operation performed by the driver of the vehicle or a braking condition during the neutral control, and controls the braking force of the vehicle when the vehicle returns from the neutral control, based on the detected braking operation or the braking condition during the neutral control.

Start control device for vehicle

An apparatus for controlling an automotive vehicle including an engine with an intake valve and/or an exhaust valve having a variable operating characteristic, a transmission having a plurality of operating positions that are selectively established, and a manually operable vehicle accelerating member, the apparatus including a target-drive-force setting portion operable to determine a target vehicle drive force on the basis of an operating amount of the accelerating member and a presently selected one of the operating positions of the transmission, such that the determined target vehicle drive force permits a smooth change of an actual vehicle drive force with a change of the operating amount of the vehicle accelerating member, irrespective of a shifting action of the transmission, and a drive-power-source-torque control portion () operable to control a torque of the engine, by controlling at least one of a lift amount, an operating period of an opening and closing action and an operating timing of the intake valve () and/or the exhaust valve (), so that the actual vehicle drive force coincides with the target vehicle drive force after the shifting action of the transmission.

A vehicular automatic shift control unit for executing a cooperative shift control (an upshift inhibition and a downshift) of an automatic transmission based on an information associated with a road condition around a vehicle or a road condition in front of the vehicle, is provided with judging means for judging whether a vehicle exists in a predetermined area including a branch point of the road during execution of the cooperative shift control, and gear ratio maintaining control means for maintaining a gear ratio of the automatic transmission if it is judged that the vehicle exists in the predetermined area.

A vehicle drive control apparatus includes an engine that generates power through combustion of fuel, an automatic transmission that transmits a reverse input from a driving wheel to the engine and automatically performs a gear shifting among a plurality of forward gear stages each having a different gear ratio, a fluid power transmission device interposed between the automatic transmission and the engine for transmitting power through fluid, the fluid power transmission device having a lock-up clutch, and a controller. The controller executes a fuel cut control for stopping supply of the fuel to the engine upon establishment of a fuel cut condition including that a vehicle is in a coasting state where a throttle valve of the engine is fully closed, and an engine speed is equal to or higher than a predetermined value, executes a control for engaging the lock-up clutch upon establishment of a lock-up clutch engagement condition including that the vehicle is in the coasting state, and executes a control of the automatic transmission for downshifting at a coast down vehicle speed that changes in accordance with a state of the lock-up clutch under the control for engaging the lock-up clutch.

Vehicle drive control apparatus and method

An automatic engine stop/restart-type vehicle and control method determine whether a vehicle is in a non-running range. The vehicle comprises: an engine; a transmission, an oil pump and a controller. The transmission has a coupling element that transmits an output torque of the engine. The oil pump supplies a hydraulic pressure to the transmission. The controller controls an output from the engine; controls the hydraulic pressure supplied to the transmission; and determines whether the engine is in an automatic stop state when a manually set mode of the transmission is shifted from a non-running range to a running range. A hydraulic pressure compensation procedure is performed to conform friction coupling characteristics of the coupling element and input characteristics of the transmission with each other if the controller determines that the engine is in the automatic stop state.

A condition for driving an electric oil pump is set. A turbine speed or an input speed of an automatic transmission is measured. A correction amount for a hydraulic pressure is calculated on the basis of the turbine speed obtained by reference to a relation between the turbine speed and hydraulic pressure, and a correction amount for a drive duty ratio of the electric oil pump which is required for generation of the corrected hydraulic pressure is calculated. The procedure is resumed after the procedure has been performed. The condition for driving the electric oil pump is updated on the basis of the correction amount for the drive duty ratio calculated.

An electric oil pump capable of suppressing wear of an electric oil pump used as auxiliary to a main oil pump to thereby prolong the life of the pump and avoid any need to provide a larger pump. An electric oil pump ( ) is operated only for a predetermined acceptable operation time, and the engine ( ) is thereafter activated to cause the mechanical oil pump ( ) to supply oil pressure. This arrangement can limit successive operating time for the electric oil pump ( ), suppressing wear of the electric oil pump ( ) and thus prolonging its life. Provision of a larger electric oil pump ( ) can also be avoided.

In the case where a cooperative gear change control of an automatic transmission is executed on the basis of information with respect to a condition around a vehicle or in front of a vehicle, in a cooperative gear change control means, a gear change of the automatic transmission is directly determined on the basis of actual curve information and road surface inclination information in accordance with a previously stored downshift map, and a gear stage is switched such that a determined gear change is executed. Therefore, it is possible to directly obtain the gear stage or the gear ratio corresponding to the curve of the road and the inclination of the road surface.
