摘要： A vehicle control unit controls a vehicle having a device capable of controlling deceleration, such as a continuously variable transmission. An information detection device is capable of determining a relationship between the instant vehicle and a preceding vehicle running in front of the instant vehicle, for example, a headway distance and a relative speed therebetween. Based on the information derived from the detection device, the vehicle correlation is determined and compared with a predetermined target correlation. Then, deceleration of the instant vehicle is set by a deceleration setting device such that the determined correlation reaches the predetermined target correlation. The device for performing deceleration is controlled based on the deceleration that has been set.

摘要： In the case where a belt return of a continuously variable transmission is not determined when the vehicle speed has become equal to or lower than a threshold value, control that causes a hydraulic actuator to have an intermediate pressure by setting a duty of a duty solenoid based on an input torque and an oil temperature and closing control are repeatedly performed, in accordance with the running and the stopping of the vehicle. As a result, it is possible to inhibit the continuously variable transmission from being shifted up due to a gradual increase in the hydraulic pressure in the hydraulic actuator caused by a line pressure seeping to the hydraulic actuator side through a small clearance in a spool of a flow rate control valve in a hydraulic circuit, and it is also possible to allow the continuously variable transmission to be shifted down.

摘要： A vehicular power transmission includes an oil pump that produces an oil pressure for a line pressure to control the applications of frictional engagement elements and for a lubrication pressure to lubricate individual mechanical portions of the transmission. A motor is provided for driving the oil pump. A control unit controls the motor. An electric oil pump control system includes an accelerator sensor for inputting acceleration data according to the operation of the accelerator pedal of a vehicle to the control unit. The control unit controls the revolutions per minute of the motor such that the amount of oil discharged by the oil pump is sufficient for outputting the line pressure matching the acceleration data and the lubrication pressure.
