The behavior model that uses traditional finite state machine method often has the bad readability. In addition, it’s difficult to expand and cut out the system function. So a new modeling approach based on quantum framework was put forward for embedded system development. The essential features and movement mechanism of quantum framework were introduced firstly. Then taking the heavy truck automated mechanical transmission as an example, developing methods and steps with QF technology for embedded system were introduced. The example study indicated that the application of QF technology in embedded system development could significantly increase the efficiency of design, code readability and maintainability of the system.
