摘要

This research uses PreScan simulation software as a test platform. The vehicle's hardware-in-the-loop (HIL) links to virtual scenes and reality sensors, which reduce costs in a virtual road environment. In this study, we monitor the analog power meter on the drive shaft of the PreSan car to monitor its torque, tire rotation speed, acceleration, and design the transmission format of the power meter. The remote monitoring is standardized, as the network interface is integrated into the car computer while retaining the high reliability of the industrial-grade Ethernet network. The system meets the strict functional safety requirements of car manufacturers and Tier 1 original equipment manufacturers (OEMs). The advanced driving assistance system (ADAS) of the car allows 1) the monitoring of the analog power meter of the Ethernet to become the mainstream data collection channel, 2) the processor of the on-board system to monitor the value and communication in real-time, and 3) drive the car to check the driving condition. Through the development of PreScan, intermediate monitoring and communication are completed, and the development speed is accelerated.
