description The invention provides a remote update system and method for an electric automobile ECU. The remote update system comprises a transmission computer arranged at a remote data center and the ECU arranged at the vehicle-mounted end and further comprises a GPRS data transceiver arranged at the vehicle-mounted end and a data recorder, wherein the transmission computer is in interactive connection with the GPRS data transceiver through an Internet network platform and a mobile network platform, the GPRS data transceiver is in interactive connection with the data recorder, and the data recorder is in interactive connection with the ECU through an CAN bus. The invention further relates to the remote update method for the electric automobile ECU. The remote update of the electric automobile ECU program is achieved, accordingly program maintenance of vehicle factories or ECU suppliers can be convenient and quick, and the technical guarantee level is improved.
