Embodiment Construction

[0014] As mentioned above, the telematics system is used to provide telecommunications and cellular connectivity to the vehicle, and can also be configured to generate an emergency call in the event of a crash or accident. The present disclosure describes a telematics system for a vehicle that establishes communications between the vehicle and other vehicles in the same or similar geographic area or outside service via a relay tower or base station. communication systems such as figure 1 The system depicted in , shows one such example of a system capable of providing communication between a vehicle and an external service. In the event of one or more crashes, accidents, mechanical failures, electrical failures, and / or medical emergencies, a request for assistance may be broadcast via relay towers and / or satellites to nearby vehicles or external services.

[0015] Additionally, as described herein, the telematics unit may include a plurality of antennas, including at least one...

Abstract

Embodiments are disclosed for an example telematics system for a vehicle. The example telematics system comprises a plurality of antennae capable of sending and receiving wireless signals, the plurality of antennae including a primary antenna and a backup antenna positioned adjacent to the primary antenna. The primary antenna comprises a three-dimensional antenna, and the backup antenna comprises a two-dimensional antenna.

Description

technical field [0001] The present disclosure relates to the field of vehicle communication systems, and in particular, to antenna systems for integrated telematics units. Background technique [0002] It is well known that emergency assistance systems are used to transmit vehicle information in the event of a crash. These systems are designed so that when an impact situation is detected, a phone call or SMS message can be initiated to the base station. The emergency system sends vehicle information to the base station, such as vehicle crash data, vehicle identification, vehicle condition, and vehicle location information. Thus, in the event of a crash, emergency services such as ambulance and / or police can be called automatically. However, the emergency system may not be able to automatically transmit such an automated emergency call if the antenna of the emergency system is damaged during the impact.
