- Abstract
- The automobile functions and reliability are increasing rapidly, but the price is decreasing. Therefore, more and more ECUs (Electronic Control Unit) will be conducted into the car. Today, there are about more than 50 ECUs being used in the high-level automobile, and people designed CAN Bus to decrease development cost for car such that ECUs can be worked coordinately. By applying the CAN Bus, we can make the ECUs communicate with each other, moreover, the data message will also be sent to each control device. Therefore, it is an important paradigm for CAN Bus in the CAR-based real time motor control system. In this paper, we first introduce the motor control that is to research how the control message is delivering out through the CAN Bus. Based on this technology, algorithm for motor control is also mentioned. Besides, to achieve much safety and reliability for the real-time motor control, we also research the automotive software framework for ERIKA Enterprise, and through the conducting of ERIKA software, the real time operating system for OSEK can be ported (embedded) into the target ECU hardware in a very easy way. Finally, we propose a demonstrative application for enhanced CAN (ECAN) bus network connection to show how real-time transmission of data frames through ECAN bus network connection is guaranteed by ERIKA Enterprise. In the other words, the motor control for CAR can also be managed by ERIKA to keep the data transmitting in more safety, reliability and real-time.
