Driving assisting system, method and vehicle incorporating the system

A system for assisting an operator in driving a vehicle. The system calculates risk potential (S300) associated with the vehicle. Responsive to an acceleration command issued by the operator via an operator-controlled input device to perform an intended acceleration operation (S400), the system conveys information related to the calculated risk potential by modifying a relationship of an amount of acceleration corresponding to an operation amount of the operator-controlled input device, based on the calculated risk potential.
