METHOD FOR ARBITRATING BETWEEN MULTIPLE VEHICLE NAVIGATION SYSTEMS
First Claim
1. An electronically-controlled method of arbitrating between multiple vehicle navigation systems that are available to an occupant on board a vehicle, comprising the steps of:
- (a) determining the operational status of at least one of first and second vehicle navigation systems that are accessible to the occupant;
(b) if more than one of said vehicle navigation systems are currently activated, then;
(b1) selecting one of said vehicle navigation systems;
(b2) running an active session for the selected vehicle navigation system; and
(b3) preventing an active session from running on the unselected vehicle navigation system.

Abstract
A method for arbitrating between vehicle navigation systems in the event that multiple systems are concurrently activated so that information is provided to a user by only one navigation system at a time. This method of arbitration reduces the possibility of user confusion that could otherwise occur if multiple vehicle navigation systems were simultaneously providing the user with information. According to one embodiment, the arbitration method is used in conjunction with a telematics-based system and a CD-based system that both provide turn-by-turn spoken driving directions. The method can also be used to arbitrate between any vehicle-based sources of electronically-supplied audio speech, particularly where the systems are connected to a common vehicle network that allows software control of the different vehicle systems.

14. A method of arbitrating between multiple vehicle navigation systems that are available to an occupant on board a vehicle, comprising the steps of:
-
(a) receiving an activation signal indicating that a first vehicle navigation system has been activated;
(b) determining the operational status of a second vehicle navigation system;
(c) if said second system is not currently activated, then running an active session for said first system; and
(d) if said second system is currently activated, then determining which of said systems the occupant wishes to use by interacting with the occupant via an interface and;
i) if the occupant selects said second system, then ignoring said activation signal; and
ii) if the occupant selects said first system, then running an active session for said first system and preventing said second system from running an active session. - View Dependent Claims (15, 16)

17. A method of arbitrating between two sources of electronically-produced speech using a vehicle-based communications network, comprising the steps of:
-
(a) providing a vehicle occupant with information supplied in the form of audible speech, wherein the information is provided to the occupant using a first vehicle system that supplies audio speech signals to one or more speakers located within the vehicle;
(b) receiving an activation signal via a vehicle network indicating that a second vehicle system that supplies audio speech signals has been activated;
(c) selecting one of the first and second vehicle systems; and
(d) allowing the selected vehicle system to supply audible speech to the occupant while preventing the unselected vehicle system from supplying audible speech to the occupant. - View Dependent Claims (18, 19, 20)
