  • Patent number: 6736756
    Abstract: A shift control apparatus of an automatic transmission of a vehicle and a method therefore is disclosed, the method comprises the steps of: discriminating whether a shift lever of the automatic transmission is switched from reverse range ‘R’ to neutral range ‘N’; calculating a lapsed time when the shift lever is set at neutral range ‘N’, if confirmation occurs that the shift lever is switched from reverse range ‘R’ to neutral range ‘N’ at a previous step and discriminating whether the shift lever is switched from neutral range ‘N’ to forward drive range‘D’; and performing a shifting operation with a different shifting oil pressure depending on the lapsed time, when the shift lever is set at the neutral range ‘N’, if confirmation occurs that the shift lever is switched from neutral range ‘N’ to the forward drive range ‘D’ at the previous step, wherein the oil temperature of the automatic tran

  • Patent number: 6652416
    Abstract: A method for controlling shifts of an auto vehicle transmission is disclosed to determine a forward running shifting process and then perform forward running operations if a range switch of the shift lever is made according to a backward running vehicle driver's intention to run forwards, after the driver considers brake pedal manipulation, the engine idle and vehicle's backward running speed at the time of a R→D range switch of the shift lever, thereby preventing the changing shift shock and reduction in strength that may be caused by wear or loss of friction elements, the method including the steps of: discriminating whether a R→D range switch signal has been input while the vehicle is running backwards; detecting the vehicle's running state if the R→D range switch signal has been input; discriminating whether the first speed shifting conditions are satisfied when the detected running states of the vehicle have been determined as follows: a brake switch is turned off, and the r
