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. Measured torque values are used during a torque phase of the upshift to correct an estimated oncoming friction element target torque so that transient torque disturbances at an oncoming clutch are avoided and torque transients at the output shaft are reduced.

A detected traction loss is signaled when the sustained drop occurred with no change between the first and second torque value readings in the throttle position, gear setting, and brake pressure. A desired throttle value is calculated using an engine torque and a target engine speed to prevent driven wheel slip.

When a clutch is disconnected, an inverter determines whether the time period in which the absolute value of the rotational speed of a motor becomes a predetermined first threshold or less and the torque of the motor becomes a predetermined second threshold or greater has continuously equaled or exceeded a predetermined third threshold. When the clutch is disconnected and it is determined that the time period in which the absolute value of the rotational speed of the motor becomes the predetermined first threshold or less and the torque of the motor becomes the predetermined second threshold or greater has continuously equaled or exceeded the predetermined third threshold, an HV-ECU controls the motor to restrict the torque of the motor and also controls the clutch to connect the clutch.

Air-fuel ratio control apparatus and air-fuel ratio control method for internal combustion engine mounted on hybrid vehicle

Номер: US20130211692A1
Автор: Yoshikazu Asami
Принадлежит: Toyota Motor Corp

A hybrid vehicle executes intermittent operation for stopping an operation of an internal combustion engine and thereafter resuming the operation in response to an operating state. An air-fuel ratio control apparatus executes air-fuel ratio feedback control for bringing an air-fuel ratio of air-fuel mixture supplied to the engine on the basis of an output of an upstream air-fuel ratio sensor and an output of a downstream air-fuel ratio sensor into coincidence with a target air-fuel ratio. The air-fuel ratio control apparatus acquires a catalyst parameter that indicates a state of the catalyst at a start of the engine through intermittent operation. The air-fuel ratio control apparatus substantially corrects the target air-fuel ratio in response to the acquired catalyst parameter in a predetermined period after a start of the engine through intermittent operation, and learns a sub-feedback amount that is calculated using the output of the downstream air-fuel ratio sensor.

To avoid excess current being supplied to the motor, the upper limit of motor speed, which is the input speed of a second clutch, is set to a value less than a slip detectable limit value at which it becomes possible to detect slip rotation, i.e. the difference over the output side rotation speed. When the target drive torque exceeds the gradient load, the lower limit of the input speed of the second clutch (the motor speed) is set to a value equal to or greater than the slip detectable limit value so that the required driving force can be achieved by the gradient load corresponding driving force control.
