Abstract
To provide a vehicle speed limiting system that is capable of executing a maximum speed limiting control without influencing a driving feeling of a vehicle. A vehicle speed limiting system includes: a three-dimensional mapand a throttle valve driving unit. A first maximum speed limiter opening degree is calculated by adding a first predetermined opening degree, a second predetermined opening degree, and a current throttle valve opening degree, the first predetermined opening degree being calculated by multiplying a speed difference of the vehicle by a preset P-term coefficient, the second predetermined opening degree being calculated by multiplying an acceleration of the vehicle by a preset D-term coefficient. Once the calculated first maximum speed limiter opening degree falls below the target throttle valve opening degree θB, the throttle valve motoris driven on a basis of the first maximum speed limiter opening degree.
