Abstract: PURPOSE: A gearshift control method executes reconfirmation to prevent miss-gearshift even when a temporary wrong signal is inputted by a driver's miss-operation of a gearshift lever. CONSTITUTION: A control method comprises four steps. The first step(S110) is to receive and read throttle valve opening amount, output shaft rotation frequency, acceleration pedal switch, oil temperature, engine rotation frequency and turbine rotation frequency detected in a vehicle driving on D range 4th speed to compare and determine whether a gearshift lever is switched from D range to 2 or L range. The second step(S120) is to compare and determine whether the engine rotation frequency is under the 3→2 gearshift allowing rotation frequency if the gearshift lever is switched from D range to 2 or L range. The third step(S130) is to compare and determine whether the objective gearshift speed is 2nd speed and the last car speed(No(n-1)) is higher than the current car speed(No) if the engine rotation frequency is under the 3→2 gearshift allowing rotation frequency. The forth step(S140) is to output 2nd speed gearshift control signal if the objective gearshift speed is 2nd speed and the condition that the last car speed(No(n-1)) is higher than the current car speed(No) is not satisfied.

Filed: 1997-11-12
Abstract: PURPOSE: A fault control circuit is provided to control switched power supplies in such apparatus during current overload conditions by utilizing a control circuit otherwise present for switching the power supply, for example an auxiliary power supply, on and off when changing between the run and standby modes of operation mode. CONSTITUTION: A voltage source, a transformer and a switching controller are coupled for switched mode generation of a regulated output supply voltage. A switching circuit responsive to an on/off signal turns the power supply on and off by establishing a conductive condition in a conductive path. A fault detector establishes a non conductive condition in a part of the conduction path responsive to an overload condition. A delay circuit establishes a conductive condition in an auxiliary conduction path for a period of time after the power supply is turned on. The auxiliary conduction path becomes non-conductive when the fault detector establishes a conductive condition in the part of the conduction path. The part of the conduction path remains conductive absent an overload condition. A latch arrangement including the delay circuit maintains the non conductive condition in the auxiliary conduction path until the power supply is turned off.
