Abstract

The embodiment of the invention provides an ECU flashing device and flashing method. The ECU flashing device comprises a universal serial bus (USB) interface circuit, a controller area network (CAN) transceiving circuit and a flashing control circuit. Tthe USB interface circuit is used for carrying out USB communication with an upper computer; the CAN transceiving circuit is used for carrying outCAN communication with an electronic control unit (ECU). A first terminal of the flashing control circuit is connected with the USB interface circuit; a second terminal of the flashing control circuitis connected with the CAN transceiving circuit, and the flashing control circuit is used for acquiring flashing data sent by the upper computer through the USB interface circuit and sending the flashing data to the ECU through the CAN transceiving circuit for flashing. The ECU flashing device provided by the embodiment of the invention is simple in structure and relatively high in practicability.
