Complexity reduction
The above describes how to divide the basic modules and functional modules, but if each optional or potentially optional electrical appliance in the car is regarded as a functional module alone, a highly complex module group will be derived. For the current technology, Obviously not suitable, because it will greatly increase the management cost. For example, dividing 4 window shakers into 4 different functional modules is a waste of module definition. Therefore, it is necessary to combine modules, optimize module management, and reduce management costs on the premise of ensuring module flexibility.
