1. A driver assistance device comprising one or more processors configured to:
determine whether a pedal misapplication determination condition is satisfied;
output, via a speaker, when the one or more processors determine that the pedal misapplication determination condition is satisfied, an audio message indicating that an accelerator pedal is depressed;
output at least one of a warning display and warning audio directly instructing a driver to release a pedal that is depressed at a point in time of outputting;
receive, from a sensor, a signal representing an operation amount of the accelerator pedal, and determine the operation amount of the accelerator pedal based on the signal;
determine, during the output of at least one of the warning display and the warning audio, whether the operation amount of the accelerator pedal becomes no more than a predetermined threshold value; and
when the operation amount of the accelerator pedal becomes no more than the predetermined threshold value, change a form of attraction of attention from a first form of directly instructing to release the accelerator pedal that is depressed to a second form of instructing to perform a brake operation and output at least one of a display and audio, via the speaker, instructing the driver to depress a brake pedal.
