Abstract

A vehicle control system is provided. The vehicle control system includes an observation module and a control profile determination module. The observation module is installed in a vehicle, which includes a location identification unit producing location information of the vehicle, and a control unit. The control profile determination module receives terrain information and weather information corresponding to the location information, determines a terrain condition type according to the terrain information, determines a weather condition type according to the weather information, and determines a suitable control profile according to the terrain condition type and the weather condition type. The control unit of the observation module adjusts control parameter(s) of the vehicle according to the suitable control profile. The disclosure further provides a vehicle control method and a non-transitory computer program for vehicle control.
