Calculation of the Vehicle Status and Control of Vehicle Functions

The vehicle status management system calculates a single vehicle status from the terminal status, vehicle movement, battery condition and status of the combustion engine. This status is then used to describe when a customer function or a group of customer functions (e.g. all entertainment functions) has to be available.

For instance, all functions for geometric adaptation are to be available in the basic control mode/stationary operation statuses. The operating states defined through vehicle status management are summarized in the following table:

VEHICLE STATUS MANAGEMENT CHART

Operating State	Identifying Feature	Function
Driving	Engine running	Active steering
Engine start	Starter motor running	Radio mute
Ready to drive	Engine OFF, driver present, ignition switched ON	This is where those functions are activated that are required for the driving mode, e.g. Park Distance Control, air-conditioning system, passive safety systems
Basic control mode	Engine OFF, driver present, ignition switched OFF	Radio, seat adjustment
Standby	Driver's absence identified by: Secure vehicle, or Non-initiation of driver interaction for 30 minutes.	Functions that have to exist when the driver is absent, e.g. DWA, CAS (read-in remote control)
