| 20120108388 | VEHICLE CONTROL APPARATUS AND VEHICLE CONTROL METHOD - A hybrid electric vehicle has a first mode in which slippage of a clutch between an electric motor and a driving wheel is allowed and controlled by rotational speed control of the electric motor and a second mode in which the slippage of the clutch is allowed and controlled by rotational speed control of an engine. When the vehicle is stationary in the first mode, a controller reduces a control setpoint of hydraulic pressure of the clutch from an initial point. The controller identifies a reference point of the control setpoint with which actual output torque of the electric motor is substantially constant with respect to the reduction of the control setpoint. Then, the controller increases the control setpoint to a precharge point, and reduces the control setpoint to a corrected point that is lower than or substantially equal to the initial point and higher than the reference point. | 05-03-2012 |

| 20120109478 | HYDRAULIC CONTROL APPARATUS FOR VEHICLE - The hydraulic control apparatus calculates a target engagement hydraulic pressure of a frictional engagement element, controls the frictional engagement element so that a revolution speed at a driving source side of the frictional engagement element is higher than a revolution speed at a driving wheel side of the frictional engagement element, outputs a command current to a solenoid valve on the basis of a map having a relationship between the target engagement hydraulic pressure and the command current, and decreases the engagement hydraulic pressure when a vehicle speed is equal to or less than a predetermined vehicle speed at which the vehicle is judged to be vehicle stop during execution of the slip control. Further, the hydraulic control apparatus corrects the map so that a variation of the command current with respect to a variation of the target engagement hydraulic pressure is small when decreasing the engagement hydraulic pressure. | 05-03-2012 |
| 20120203406 | VEHICLE CONTROL APPARATUS AND VEHICLE CONTROL METHOD - A hybrid electric vehicle has a first mode in which slippage of a clutch between an electric motor and a driving wheel is allowed and controlled by rotational speed control of the electric motor and a second mode in which the slippage of the clutch is allowed and controlled by rotational speed control of an engine. When the vehicle is stationary in the first mode, a controller reduces a control setpoint of hydraulic pressure of the clutch from an initial point. The controller identifies a reference point of the control setpoint with which actual output torque of the electric motor becomes unchanged with respect to the reduction of the control setpoint. Then, the controller increases the control setpoint from the reference point at a higher gradient and then a lower gradient, and then sets the control setpoint to a corrected point below the initial point and above the reference point. | 08-09-2012 |
| 20130098728 | AUTOMATIC TRANSMISSION CONTROLLER - An automatic transmission is provided with a frictional engagement member that is operated by hydraulic pressure for shifting the automatic transmission, and includes an air vent opening. An automatic transmission controller includes a pressure regulator and a control section. The pressure regulator regulates the hydraulic pressure in response to a hydraulic pressure control signal. The control section performs an air vent operation of venting air from the frictional engagement member through the air vent opening. The air vent operation includes: a preliminary operation of setting the hydraulic pressure control signal to a preliminary pulse indicative of a preliminary value of pressure, wherein the preliminary value is lower than a normal value of pressure; and a normal operation of setting the hydraulic pressure control signal to a normal pulse indicative of the normal value, wherein the normal pulse follows the preliminary pulse. | 04-25-2013 |
