This work describes the development of a nonfatigating Brain–Computer Interface (BCI) based on Steady State Evoked Potentials (SSVEP) and Event-Related Desynchronization (ERD) to control an autonomous car. Through a graphical interface presented to the user in the autonomous car, destination places are shown. The selection of commands is performed through visual stimuli and brain signals. The signals are captured on the occipital region of the scalp, and are processed in order to obtain the necessary data for the planning system of the autonomous car. Test performed obtained success rate of 90% for a synchronous BCI and 83% for an asynchronous BCI. The proposed system is a hybrid-BCI, which includes the ability to enable and disable the visual stimuli, reducing fatigue associated with the use of SSVEP-based BCIs.
