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,
when it is determined that the pedal misapplication determination condition is satisfied, execute driving force restriction control while outputting at least one of the warning display and the warning audio, the driving force restriction control being a control of setting a driver-requested driving force corresponding to an operation amount of the accelerator pedal to be smaller than the driving force in operations in which no pedal misapplication is determined; and
when the operation amount of the accelerator pedal becomes no more than a predetermined threshold value while executing the driving force restriction control, 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 instructing the driver to depress a brake pedal.
