Problems solved by technology

[0006] However, it is currently not possible to accurately measure the degradation state of PRA
In addition, since the technology that can actively control the heat generation of PRA has not been developed, the deterioration of PRA may be accelerated, and PRA may cause fire due to overcurrent

Abstract

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.

Description

technical field [0001] The present invention relates to a power relay assembly (PRA) degradation control system for a vehicle, and in particular, relates to a PRA degradation control for a vehicle that can predict failure of a PRA and actively control the degradation of the PRA by utilizing big data System and PRA degradation control method thereof. Background technique [0002] Generally, as one of the proposals for improving the global environment, a hybrid electric vehicle (HEV), an electric vehicle (EV), a fuel cell vehicle (FCV), and the like have been developed and operated. In particular, the development of electric vehicles is expected to become more prominent in the future. [0003] Such an electric vehicle or a hybrid electric vehicle includes a high-voltage battery and a high-voltage circuit unit for supplying electric power to a motor as a driving source. [0004] The high-voltage circuit unit may include: a motor receiving power supplied from a high-voltage ba...
