Method and system for resetting tire pressure monitoring system for an automotive vehicle
First Claim
1. A method comprising the steps of:
- determining a vehicle speed;
when the vehicle speed is below a speed threshold, generating a preamble signal and a data signal using a first protocol from a tire pressure sensor and also generating another preamble signal and another data signal using a second protocol from the tire pressure sensor;
when the vehicle speed is above the speed threshold, generating a preamble signal and a data signal using the second protocol from the tire pressure sensor;
when the vehicle speed is below the speed threshold, operating a receiver using the first protocol; and
also using the second protocol; and
when the vehicle speed is above the speed threshold, operating the receiver using the second protocol.

Abstract
A tire pressure monitoring system (12) for a vehicle (10) includes a vehicle speed sensor (38, 98) that is used to generate a vehicle speed signal. A receiver (28) operates using a first protocol when the vehicle speed signal is below a first speed threshold and operates using a second protocol when the vehicle speed is above the speed threshold. A remote keyless entry system (23) is coupled to the receiver and operates when the vehicle speed is below a speed threshold. The remote keyless entry system (23) receives signals from a keyless entry transmitter (60) using the first protocol. A tire pressure monitoring system (12) has a pressure transmitter (16A-16E) that generates a signal using a first protocol and a second protocol when the speed signal is below the speed threshold and generating the signal using only the second protocol when the speed signal is above the speed threshold.
