Abstract
A vehicle may include a transmission control unit (TCU) to output a control signal to the transmission; a shift lever; a shift lever electronic control unit (ECU) to transmit a first signal and a second signal, to the TCU; a main communication unit to perform communication between the TCU and the shift lever ECU; a backup communication unit to perform communication between the TCU and the shift lever ECU; and a controller configured to: control the shift lever ECU to transmit first and second signals based on one of a plurality of matching codes having different pulse width modulation (PWM) duty ratios assigned to the respective gear positions of the transmission; determine another one of the plurality of matching codes when the operation commands indicated by each of the first signal and the second signal received by the TCU are different; and control the shift lever ECU based on the determined matching code.
