Abstract: By using object oriented method and multi-thread technique, an online-monitoring system for the process information of vehicle electronically controlled system is developed in this paper, which is based on serial communication between epigynous and hypogynous machines. The system is applied to the development of automatic transmission control unit to post the micro-work process of control system successfully, and has highly practicable worthiness.
