Power Relay Assembly Deterioration Control System for Vehicles and Power Relay Assembly Deterioration Control Method Thereof

摘要

Disclosed are a power relay assembly (PRA) deterioration control system for vehicles capable of predicting breakdown of the PRA and actively controlling deterioration of the PRA using big data and a PRA deterioration control method thereof. The PRA deterioration control system includes a vehicle configured to transmit PRA and battery information and a server configured to collect the PRA and battery information of the vehicle and to transmit output control information for PRA deterioration control to the vehicle, wherein, upon collecting the PRA and battery information of the vehicle, the server groups the collected information, sets a monitoring step by vehicle based on the grouped information, performs monitoring by vehicle in response to the set monitoring step by vehicle, and transmits output control information by vehicle corresponding to the result of monitoring to the vehicle such that each vehicle performs PRA deterioration control.
