Curve Recognition

This feature is activated when the GS 20 detects a variation of front wheel speeds via the CAN bus. The Mark 20 EI control module broadcasts the wheel speed sensor signals and their speed variations for any control module programmed to monitor this condition. When curves are recognized, the GS 20 inhibits up shifting until the front wheel speed signals equalize indicating the vehicle is driving straight ahead. This feature enhances the vehicle handling characteristics when cornering at higher speeds.
