Vehicle Status Management: Notes

Vehicle status management is a system function with the task of implementing standardized system behavior in different operating conditions for all future BMW vehicles.

For instance, the different switch-on behavior of the radio. To switch on the radio in the E65, the START-STOP button must be pressed (Terminal R is switched on). In the E90, on the other hand, the radio can also be switched on without inserting the key's remote control into the insertion slot.

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 define when a customer function or a group of customer functions (e.g. all entertainment functions) has to be available.

Furthermore, the vehicle status management system controls the operating mode the vehicle or specific modules are in. Those functions that are to be available in a mode are controlled.

Example:  No radio operation while in the transportation mode.

Distinction is drawn between the following operating states:

• Standby
• Basic control mode
• Ready to drive
• Engine start
• Driving

A further vehicle status management task is the simultaneous start up and shut down of the on-board communication network.
