SAFETY CONTROL METHOD CORRESPONDING TO UNINTENDED SUDDEN ACCELERATION OR SUDDEN DECELERATION OF A VEHICLE, CAPABLE OF RAPIDLY CONTROLLING THE VEHICLE BY CONTROLLING OUTPUT OF A PLANET GEAR SET IN AN OPTIMAL LEVEL
PURPOSE: A safety control method corresponding to unintended sudden acceleration or sudden deceleration of a vehicle is provided to safety control the vehicle by controlling operation fluid pressure to compulsively operate or disassemble a planet gear set.;CONSTITUTION: A safety control method corresponding to unintended sudden acceleration or sudden deceleration of a vehicle determines whether the vehicle maintains normal driving state in sudden acceleration or sudden deceleration of the vehicle. When the vehicle is in abnormal driving state, control beginning condition is confirmed(S10). When the normal driving state of the vehicle is confirmed, operation of braking is confirmed(S20). When sudden acceleration of the vehicle is confirmed, sudden increase of rotation speed of an output terminal in a planet gear set is prevented(S30). When sudden deceleration of the vehicle is confirmed, sudden reduction of the rotation speed of the output terminal in the planet gear set is prevented(S40).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S10) Control starting condition confirming step; (S20) Braking confirming step; (S30) Sudden acceleration handling step; (S31) Braking time confirming step; (S32,S41) Throttle opening degree confirming step; (S33,S42) Vehicle speed and vehicle speed change rate confirming step; (S34,S43) Driving mode confirming step; (S35) Accelerated time confirming step; (S36,S45) Safety mode executing step; (S40) Rapid deceleration handling step; (S44) Decelerated time confirming step;
