Rapid acceleration suppression device

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.
