System/ Component Description
The vehicle emergency message system (Jaguar Assist) allows a user to request emergency assistance (police, ambulance, fire) or roadside assistance. Also, if any of the vehicle's airbags are deployed while Jaguar Assist is operational, the system automatically issues a call for emergency assistance.
- The Jaguar Assist consists of four components
The VEMS module controls the system. It is connected to the vehicle's cellular phone system, audio unit, restraint control module (RCM), navigation system and GPS antenna. The VEMS module uses the cellular phone system to place calls to the response center. Jaguar Assist mutes the audio unit upon placing a call and re-instates the audio when the call is ended. The RCM monitors the air bag circuit to determine if an airbag has deployed and provides the user with visual feedback during an activation by displaying status messages on the navigation display.
The navigation display provides the user with one button (i) for activating the system. The navigation display is used to place a call for emergency and roadside assistance.
The GPS antenna receives data from a group of GPS satellites and is used by the VEMS module to determine the location of the vehicle when the system is activated.
