Problems solved by technology

At present, most of the existing ECU hardware is designed and implemented for traditional diesel engines or gasoline engines, and cannot be directly used for fuel cell hybrid electric vehicles.
In addition, the old-style ECU has the following problems in varying degrees in terms of hardware: In the system core, the processing capability of the microcontroller chip of the ECU cannot meet the needs of the new generation of control, and the storage space expanded for the ECU cannot meet the requirements of data storage; In terms of functional modules, the input and output ports of the ECU are not rich enough to meet the complex application requirements of the controller; in the
