Abstract:
1. A collision avoidance method for transmitting data from multiple wireless tire condition sensors mounted on a vehicle, wherein each wireless tire condition sensor has a unique ID (identification) and multiple wake-up times differing in time duration, the collision avoidance method executed by each wireless tire condition sensor after the wireless tire condition sensor is operated to sense tire condition information and having steps of: reading the ID thereof and computing to obtain a determination value with the ID and a first variable; determining if the determination value satisfies a preset condition; selecting one of the wake-up times according to the determination result; after the selected wake-up time expires, starting transmitting the sensed tire condition information; determining if an update computation condition is satisfied; and if the update computation condition is satisfied, computing a new determination value with the ID and a second variable and resuming the step of determining if the determination value satisfies the preset condition.
