Patent EP-0742386-A3 (EP)
IPC: B60W10/10
Filed: 1996-05-09
Abstract: A control system for an automatic transmission, 
comprising: a clutch (C1) for transmitting the rotation of 
an engine (10) to the transmission mechanism (16) of a speed 
change unit; a hydraulic servo (C1) for applying/releasing 
the clutch; starting state detecting means (100) for detecting 
the vehicle starting condition in which at 
least one of the following conditions is dissatisfied: 
that the throttle opening is fully closed; that the 
brake pedal is depressed; and that the vehicle speed 
is substantially zero; throttle opening detecting 
means for detecting the throttle opening of the engine; 
applied/released state detecting means for detecting 
the applied/released state of the clutch; 
hydraulic control means for controlling the oil pressure 
to be fed to the hydraulic servo; and a control 
unit. When the starting state detecting means detects 
the vehicle starting state, the control unit detects 
the actual applied/released state of the clutch to 
determine the difference between the applied/released 
state and an ideal applied/released state read out 
from applied/released state characteristic storing 
means (106), thereby to set an oil pressure correction according 
to that difference. Next, an oil pressure for 
achieving the engaging characteristics of the clutch 
is read out from fed characteristic storing means (105). 
The oil pressure correction is added to the read oil 
pressure, and the sum is outputted to the hydraulic 
control means (103). As a result, even if an error occurs 
in the output of the control valve of the hydraulic 
control means or if an aging occurs in the clutch, the 
oil pressure is corrected by the oil pressure correction 
according to the difference between the actual 
applied/released state and the ideal applied/released 
state so that the engaging characteristics obtained 
can be approximate the ideal ones.

Abstract: A method and system (130) for controlling sensed CPU dynamic
operating characteristics includes the steps of and circuitry for
sensing at least one dynamic CPU operating characteristic (140)
while the CPU operates at a first clock rate (134). The system
(130) determines that a setpoint interrupt condition exists (140)
by virtue of the at least one sensed CPU dynamic operating
characteristic establishing a predetermined relationship relative
to a predetermined setpoint (140) that associates with the at
least one dynamic operating characteristic. In the event that the
setpoint interrupt condition exists, the circuitry and
instructions control (144) the clock rate relative to the first
clock rate. In the event that the setpoint interrupt condition
does not exist, the circuitry and instructions repeat the above
steps of determining the interrupt condition and controlling the
clock rate. The method and system (130) also determine whether the
CPU is in a compute-bound state (142). This operation in
conjunction with a real-time power conservation apparatus and
method (20) is a particularly attractive feature of the present
invention.
