Abstract: A method for diagnosing leakage of electronic parts and servicing guide of a driving state for a vehicle in a battery management system is provided. The method includes normally driving the vehicle or stopping the vehicle by cutting off a relay based on whether electronic parts broken due to insulation resistance breakdown are required for the driving of the vehicle. In addition, the method includes services a guide required for each broken electronic part about a driving state of the vehicle, by stepwise measuring insulation resistance of vehicle key on, engine starting, an operation of load parts such as a driving motor in the vehicle, an air conditioner, and a low-voltage DC-DC converter, and the like.
Abstract: A computer implemented method for performing route guidance using text includes obtaining an optimal route that connects a start point and an end point of a route input by a user; comparing a route history stored in a memory with the optimal route and extracting a route portion from the optimal route, the route portion being replaceable by a route portion in the route history; creating route guidance for the route portion extracted from the optimal route by using a text indication known to the user, the known text indication specifying the replaceable route portion in the route history; and creating route guidance for a route portion in the optimal route, the route portion being not replaceable by a route portion in the route history, by using a new text indication that specifies the route portion that is not replaceable.
