Embodiment Construction
[0021] This embodiment provides a method for developing an electronic control strategy for a new energy vehicle. First, after the functional requirements of the vehicle are determined, the functional decomposition begins, and the functions of the pure electric control system are divided into power management modules, accessory management modules and Torque management modules, but not limited to the above modules;
[0022] Secondly, in the power management module, accessory management module and torque management module, the input and output interfaces of the modules themselves and the fault diagnosis module are respectively defined, and the sub-function modules of each module are enclosed inside the module;
[0023] Finally, each module is integrated to develop a pure electric vehicle vehicle controller strategy;
[0024] Develop the power-on operation in power-on and power-off management:
[0025] Such as image 3 As shown: the traditional development steps are: define the ...
