1. A system of controlling a vehicle, the system comprising a sensor and a controller,
wherein the sensor is configured to sense a vehicle operation state to generate sensed vehicle operation state information, and
the controller is configured to:
determine whether a vehicle is running on a dangerous road based on the sensed vehicle operation state information,
determine whether there is a possibility that a vehicle driving state will cause a failure of a driving system based on the sensed vehicle operation state information in response to determining that the vehicle is running on the dangerous road, and
decide that torque control of the vehicle is required and control the vehicle torque in response to determining that there is the possibility that the vehicle driving state will cause the failure of the driving system;
wherein the controller is further configured to decrease the vehicle torque to a set value with a predetermined first change rate when the vehicle torque is controlled, and
wherein the controller is further configured to increase the vehicle torque with a predetermined second change rate in response to determining that the vehicle is not running on the dangerous road or determining that there is no possibility that the vehicle driving state will cause the failure of the driving system after decreasing the vehicle torque to the set value with the predetermined first change rate.
