Provided are a single-board type vehicle driving information measuring apparatus and method using a sum of absolute difference (SAD) hardware accelerator. In the vehicle driving information measuring apparatus and method, time differences between vehicle sensing signals sensed by two or more sensing units are accurately calculated in real time by the SAD hardware accelerator, and the velocity and acceleration of a vehicle can be accurately calculated based on the accurate time differences between the vehicle sensing signals. The vehicle driving information measuring apparatus is operated in two separate modes, that is, a vehicle sensing mode and a velocity measuring mode. Accordingly, power consumption of the apparatus can be minimized. In addition, the apparatus can be provided with a wireless transceiver, so that the apparatus can be constructed and operated without external cables. Further, functional blocks of the apparatus can be powered separately.
