Cruise Control
Cruise control functions are activated directly by the multifunction steering wheel to the EMS. The individual buttons are digitally encoded in the MFL switch and are input to the EMS2000 over a serial data wire. Cruise Control is integrated into the EMS2000 because of the MDK/EDK operation.
- The EMS2000 controls vehicle speed by activation of the Electronic Throttle Valve (EDR).
- The clutch switch disengages cruise control to prevent over-rev during gear changes.
- The brake light switch and the brake light test switch are input to the EMS2000 to disengage cruise control as well as fault recognition during engine operation.
Road speed is input to the EMS2000 for cruise control. The vehicle speed signal for normal engine operation is supplied from the DSC module (right rear wheel speed sensor). The road speed signal for cruise control is supplied from the DSC module. This is an average taken from both front wheel speed sensors, supplied via the CAN bus.
