3.5 AUTO-GUIDANCE STEERING STATE MACHINE
When the Auto-guidance device is mapped and enabled, PVED-CLS offers configurable risk mitigation functions that
will be shared by both GPS and GPS2, except for gain-parameters which are separate for GPS and GPS2. Find more
information regarding auto-guidance devices and the configuration in chapter 12.
Below Figure , Figure and Figure 10 shows auto-guidance steering state machine. The auto-guidance state machine
ensures that the selected auto-guidance controller follows the agreed protocol and to provide the auto-guidance
controller with the required status information. State transitions are triggered by information from:
• The selected auto-guidance controllers
• MMI controller
• Steering wheel sensor (for OSPE, EHi-E and EHPS)
• Internal Monitoring Disengage (for EHi-H)
• AUX device
