1. A system for limiting a maximum acceleration of a motor driven vehicle, the system comprising:
a wheel speed sensor configured to detect a vehicle speed of the motor driven vehicle;
an accelerator pedal position sensor configured to detect an amount of accelerator pedal depression; and
a control unit configured to:
estimate an acceleration based on the vehicle speed detected by the wheel speed sensor, and
control a motor torque to be an acceleration limit torque, thereby limiting an acceleration of the motor driven vehicle to a target acceleration when the estimated acceleration is equal to or higher than a reference acceleration.
