Abstract
A vehicle and a method of controlling the vehicle are provided. The method of controlling the vehicle includes detecting, by an excitation voltage computational measuring device, an excitation voltage applied to an excitation coil of a relay provided to regulate power supply of a battery; calculating, by a logical determination device, a temperature of the relay based on the excitation voltage; and calculating, by the logical determination device, a remaining life of the relay based on the calculated temperature of the relay.
Claims14
A method of controlling a vehicle, the method comprising:
- detecting, by an excitation voltage computational measuring device, an excitation voltage applied to an excitation coil of a relay provided to regulate power supply of a battery;
- calculating, by a logical determination device, a temperature of the relay based on the excitation voltage;
- calculating, by the logical determination device, a remaining life of the relay using a temperature difference between the temperature of the relay and a preset reference temperature, a number of high temperature diagnosis, and a S-N life curve;
- and
- limiting, by the logical determination device, an output of the battery when the calculated temperature of the relay exceeds the preset reference temperature.
