摘要： A fail-safe control device for an electronically controlled automatic transmission to be mounted on a vehicle arranged in such a manner that the number of engine revolution or the number of revolution input to a T/M is detected, the duration of the engine revolving state is counted, and it is determined that a failure of the engine water temperature sensor occurs if the engine water temperature detected by the engine water temperature sensor after a predetermined time elapse counted is lower than a predetermined temperature. As a result of this, a proper fail-safe control against the failure of the engine water temperature sensor can be performed.

摘要： A fail-safe control device for an electronically controlled automatic transmission to be mounted on a vehicle, the fail-safe control device: detects the battery voltage; previously stores a standard battery voltage; makes a comparison between the thus-detected battery voltage and the above-described standard battery voltage; and switches to an emergency mode of turning off all of shift solenoids when the voltage deviates from the standard upon the comparison. As a result of this, generation of defects that shifting from high speed gear stage to a lower speed gear stage due to defective operation of the shift solenoid and disconnection or the like due to the overvoltage of the solenoid can be prevented. Furthermore, if a failure is detected, it can be notified to a drive.

摘要： The control system for a linear solenoid valve controls output of an oil pressure according to a current value to be fed to the linear solenoid which operates the linear solenoid valve. A solenoid current monitor detects the current value fed to the linear solenoid and an IG voltage monitor detects the voltage level of the battery. A linear solenoid current value setting unit sets a target current value according to a target oil pressure level and a duty ratio setting unit sets a duty ratio for applying the battery voltage to the linear solenoid on the basis of signals coming from the current monitor, the voltage monitor and the current value setting unit. A solenoid driver applies the battery voltage to the linear solenoid for a predetermined period in accordance with the duty ratio set by the duty ratio setting unit. The duty ratio setting unit, in turn, includes: a feedback correction unit for feedback correction of the duty ratio, in accordance with the difference between the current value detected by the monitor and the target current value set by the current value setting unit, so that the current value fed to the linear solenoid approaches the target current value; and a voltage correction unit for further correcting the duty ratio, as previously corrected by the feedback correction unit, on the basis of the voltage level of the battery, as detected by the voltage monitor.

摘要： A control system for an automatic transmission which includes a fluid transmission unit. The control system includes a clutch applied in a forward running range; a hydraulic servo for applying the clutch responsive to an oil pressure; input and output R.P.M. sensors for detecting the input and output R.P.M.s of the fluid transmission unit; a stop state detector for detecting that the vehicle is stopped; a start detector for detecting start of the vehicle from a stop; and a control unit for controlling the oil pressure fed to the hydraulic servo. The oil pressure of the hydraulic servo is reduced, when the vehicle is stopped, to establish a neutral control state in which the clutch is released. A completely applied state of the clutch is established by boosting the oil pressure fed to the hydraulic servo when the shift of the vehicle from a stop to start is detected, in two stages. In the first stage the oil pressure fed to the hydraulic servo is boosted by adding a set shelf pressure to the base pressure until the clutch comes into a partially applied state and then, in the second stage, the oil pressure fed to the hydraulic servo is further boosted until the clutch becomes completely applied.
