SYSTEM AND METHOD FOR MONITORING ABOUT BUTTON INPUT

PURPOSE: A button input monitoring system and method are provided to secure stability of button input signals and remove unavailable button input signals, thereby preventing malfunction of a vehicle. CONSTITUTION: A button input monitoring method comprises the steps of: transmitting button input signals to first and second controllers(200,300), generating activation or deactivation event by the first and second controllers, creating the button input signals delayed by monitoring of the first and second controllers into first and second indirect input signals, transferring the first indirect input signal to the second controller and the second indirect input signal to the first controller, creating an execution event corresponding to each indirect input signal by the first and second controllers, discriminating vehicle driving information based on the executed event and creating a control request signal for a vehicle, and determining whether the control request signal can be executed and performs control for the vehicle corresponding to the control request signal according to the determination result.
