Method and apparatus are disclosed for controlling vehicle TPMS sensor localization. An example vehicle includes a plurality of tire pressure monitoring system (TPMS) sensors, a communication module, and a controller. The controller is to detect an initiation event associated with the vehicle, and, in response to detecting the initiation event, determine whether first localization information is valid based on information associated with the TPMS sensors. The controller is also to initiate, via the communication module, a localization procedure at the TPMS sensors when the first localization information is not valid.

Received acceleration or motion information are analyzed and when the analysis of this information indicates that motion or acceleration is detected, received burst patterns from the other sensors are analyzed. Based upon analyzing the detected burst patterns from the other sensors, a first burst pattern is selectively altered to transmit according to a single communication format, the single format being for a single vehicle manufacturer.
