DRIVING SUPPORT METHOD FOR VEHICLE AND DRIVING SUPPORT SYSTEM

摘要

A driving support system for a vehicle that is equipped with an exhaust emission control device that includes a catalyst (34), that is recovered by a reducing agent (R) and also equipped with a navigation system (51) that displays the current vehicle location together on a display (52). The driving support system includes a reducing agent level sensor (41) that detects the amount of reducing agent (R) in a reducing agent tank (36); and an allowable travel distance calculation device that calculates an allowable travel distance of the vehicle based on the detected amount of reducing agent (R). The navigation system (51) displays the locations of the reducing agent supply points within the allowable travel distance of the vehicle from the current vehicle location.
