摘要： Disclosed is a vehicle control apparatus that can concurrently achieve an improved drivability and an excellent restart performance of an internal combustion engine. The vehicle control apparatus includes an eco-run system that automatically stops the engine when an automatic stop condition is established and restarts the engine when a restart condition is established, a throttle motor that opens and closes a throttle valve adjusting air amount to be sucked into the engine, and a vehicle speed sensor that detects the vehicle speed. The vehicle control apparatus is adapted to control the throttle motor to enlarge the throttle valve opening degree in response to the higher vehicle speed, according to the vehicle speed information from the vehicle speed sensor (Step S3 to Step S7), when the engine is automatically stopped while the vehicle is travelling (Step S2).

摘要： A multiple clutch transmission control apparatus performs gear changing smoothly by improving clutch torque control precision, without reducing the speed of gear changing, in a vehicle or the like including a multiple clutch transmission. With this control apparatus, a control unit switches the transmission gear from the previous gear to the next gear by changing the torque transfer path by controlling the first clutch and the second clutch in a clutch changeover period. In the clutch changeover period, the control unit changes the torque transfer path by raising the clutch torque capacity of whichever of the first clutch and the second clutch is the next-gear-side clutch to reach a target value, and then lowering the clutch torque capacity of the previous-gear-side clutch.

摘要： Improved methods for executing a clutch-to-clutch quasi-asynchronous shift in a hybrid transmission, and a hybrid transmission using the same, are presented herein. The method includes: pre-filling the on-coming clutch; determining if the shift is completed using the on-coming or off-going clutch; slipping the off-going clutch first if the shift operation uses the off-going clutch; determining on-coming clutch slip speed and acceleration profiles; determining if the on-coming clutch is filled and whether the slip sign is correct; if using the off-going clutch, locking the on-coming clutch and exhausting the off-going clutch if the on-coming clutch is filled and the slip sign is correct; if using the on-coming clutch, determining whether the on-coming clutch slip is less than a slip threshold and exhausting the off-going clutch if the on-coming clutch is filled and the slip sign is correct; and locking the on-coming clutch if the slip is less than the slip threshold.

摘要： A control system for a transmission includes an actuator module, a timer module, and a pulse module. The actuator module engages N hydraulic clutches and disengages M hydraulic clutches to operate the transmission in a gear ratio, wherein N and M are integers greater than zero. The timer module determines a first period starting when the transmission begins operating in the gear ratio. The pulse module selectively supplies a pressure pulse to P of the M hydraulic clutches based on the first period, wherein P is an integer greater than zero. A method for controlling a transmission is also provided.

摘要： A control system and method for controlling a multiple gear ratio automatic transmission in a powertrain for an automatic transmission having pressure activated friction torque elements to effect gear ratio upshifts. The friction torque elements are synchronously engaged and released during a torque phase of an upshift event as torque from a torque source is increased while allowing the off-going friction elements to slip, followed by an inertia phase during which torque from a torque source is modulated. A perceptible transmission output torque reduction during an upshift is avoided.

摘要： A hydraulic control apparatus of an automatic transmission including a switching portion which, at the same time as a reverse range pressure oil passage and a discharge delay oil passage which delays an oil pressure output are connected, causes the reverse range pressure oil passage and discharge delay oil passage, by switching between the two, in order to communicate with a hydraulic servo. The switching portion causes the hydraulic servo and discharge delay oil passage to communicate when a manual valve is switched to an N range, and causes the hydraulic servo and reverse range pressure oil passage to communicate when the manual valve (MV) is switched to a D range or an R range. Because of this arrangement, it is difficult for oil, when discharged from the hydraulic servo, to drain at an R-N switching time, and it is easy for oil to drain in the D range or the like.
