1. A rapid acceleration suppression device of a subject vehicle, wherein
the rapid acceleration suppression device is mounted in the subject vehicle to which a plurality of driving modes of types different from each other is set, the plurality of driving modes having drive force characteristics different from each other,
the rapid acceleration suppression device provides a rapid acceleration suppression control over the subject vehicle such that a rapid acceleration thereof caused by an abnormal operation of an accelerator is suppressed,
the rapid acceleration suppression device comprises:
an information acquisition part configured to acquire information on vehicle speed, time-series information on accelerator position, and information on drive force characteristics with respect to a current driving mode;
a determination part configured to determine whether or not an operation of the accelerator has been performed abnormally, based on the time-series information on accelerator position; and
a control part configured to provide control over a drive force of the subject vehicle, based on a current vehicle speed and a current accelerator position, and
when the determination part determines that the operation of the accelerator has been performed abnormally, the control part provides a drive force suppression control in which: a target accelerator position limit value is calculated, based on the information on drive force characteristics corresponding to the current vehicle speed and the current driving mode; and a drive force of the subject vehicle is suppressed, based on the calculated target accelerator position limit value without considering an operation amount obtained through a sensor of the accelerator.
