Abstract

A communications and access system for a vehicle includes a vehicle module including a microprocessor and a sensor device integrated within each tire of a vehicle. The sensor device includes a tire pressure monitoring sensor and an antenna communicatively coupled to the sensor device. The antenna is configured to receive tire pressure data from the sensor device and a wireless communication from a device external to the vehicle. The system also includes another antenna communicatively coupled to the vehicle module. The other antenna receives the tire pressure data and the wireless communication transmitted by the sensor device via the antenna coupled to the sensor device. The system further includes logic executable by the microprocessor. The logic is configured to identify sources of the tire pressure data and the wireless communication, and transmit instructions to a body control module of the vehicle. The instructions are configured to perform a corresponding function.

Claims
