1. An alarm apparatus for an automatic transmission, comprising:
- a transmission control unit (TCU) controlling the automatic transmission of a vehicle;
an accelerator pedal unit;
a driving unit driving the accelerator pedal unit to perform a predetermined operation; and
a control unit interworking with the TCU and controlling the driving unit such that the accelerator pedal unit performs the predetermined operation at a predetermined time before a speed change time, when the speed change time calculated and outputted by the TCU is inputted to the control unit;
wherein the driving unit includes;
a driving actuator;
a connection mechanism transmitting a driving force of the driving actuator to the accelerator pedal unit; and
a position sensor sensing a position of the connection mechanism based on the driving of the driving actuator; and
wherein the control unit controls the driving actuator by using positional information inputted from the position sensor such that the driving force of the driving actuator is transmitted to the accelerator pedal unit through the connection mechanism and the accelerator pedal unit performs the predetermined operation.

6. A method for controlling an alarm apparatus for an automatic transmission, which includes a driving unit driving an accelerator pedal unit of a vehicle and a control unit interworking with a transmission control unit (TCU) of the automatic transmission to control the driving unit, the method including:
-
controlling, by the control unit, the driving unit such that the accelerator pedal unit performs a predetermined operation at a predetermined time before a speed change time, when the speed change time calculated and outputted by the TCU is received; determining, by the TCU, whether an accelerator position sensor (APS) value is increased or not by using positional information inputted from an APS installed in the vehicle, when the accelerator pedal unit performs the predetermined operation; and generating, by the TCU, a change control signal for changing a shift stage of the automatic transmission or a maintenance control signal for maintaining a current shift stage of the automatic transmission, based on the determination result of whether the APS value increased or not, and controlling the automatic transmission; wherein the driving unit includes; a driving actuator; a connection mechanism transmitting a driving force of the driving actuator to the accelerator pedal unit; and a position sensor sensing the position of the connection mechanism based on the driving of the driving actuator; and wherein the control unit controls the driving actuator by using the positional information inputted from the position sensor such that the driving force of the driving actuator is transmitted to the accelerator pedal unit through the connection mechanism and the accelerator pedal unit performs the predetermined operation. - View Dependent Claims (7, 8)
