Abstract
Provided is a speed limiter, wherein a vehicle speed is detected, and a speed limit displayed on a speed sign is detected based on an image captured by a front monitoring camera. A speed difference between the vehicle speed and the speed limit is calculated, and an accelerator sensitivity gain is set using the speed difference as a parameter. Then an accelerator opening degree is corrected with the accelerator sensitivity gain to obtain a pseudo accelerator opening degree. A target throttle opening degree is set based on the pseudo accelerator opening degree and an engine rpm.
