Digital Map Enhancements of Electronic Stability Control

Digital maps are being linked to Advanced Driver Assistance Systems (ADAS) in numerous ways. Digital map data effectively provides a road predictive capability with a quasi-infinite range. We study the use of digital map attribute data in the enhancement of Electronic Stability Control (ESC). An offline study was conducted using real-world steering input records from participants in a prior ESC study at the National Advanced Driving Simulator (NADS). In all cases, the RMS yaw rate error was significantly reduced using the map-enhanced algorithm over the traditional ESC system. Additionally, many cases also showed improvements in other measures, such as lane deviation.
