Disclosed is an apparatus for generating a vehicle speed signal that can minimize the number of arithmetic operations of an electronic control device. The apparatus includes a PG-B (Pulse Generator B) sensor that is mounted to an output shaft of an automatic transmission, and outputs pulses according to the rotation of the transmission output shaft, a counter that counts pulses from the PG-B sensor and of the predetermined number of pulses are counted, outputs a pulse counter (PC), a vehicle speed signal generation unit that generates a vehicle speed signal in synchronization with the pulse counter (PC) from the counter, an error correction unit that corrects an error in the vehicle speed signal having decimal places from the vehicle speed signal generation unit and defines the vehicle speed signal by an integer ratio, and a speedometer that visualizes and displays the error-corrected vehicle speed signal as a current vehicle speed.
