Abstract: A collision avoidance method for transmitting data from multiple wireless tire condition sensors on a vehicle is executed by each wireless tire condition sensor having a unique ID and multiple different wake-up times. After the sensor is operated to sense data, the method has steps of reading the ID and computing a determination value with the ID and a variable, selecting one of the wake-up times according to the determination result, and after the selected wake-up time expires, transmitting the sensed data. As the selected wake-up times of the sensors differ from one another, data collision at the receiving end arising from data transmission from the sensors can be avoided. Additionally, besides the wake-up time, a time gap between data transmitted twice consecutively from each sensor can be employed to achieve data collision avoidance.

Abstract: In a tire pressure detecting apparatus, a receiver stores wheel positions detected by a previous wheel position detection as previous wheel positions. When an ignition switch is turned on and until wheel positions are newly specified by a current wheel position detection, the receiver permits an indicator to indicate tire pressure of each of wheels based on the previous wheel positions to notify a driver of the tire pressure from an earlier timing. The receiver permits the indication of the tire pressure based on the previous wheel positions only when a difference of the tire pressure between the wheels is equal to or less than a threshold. If there is a possibility that tire pressure of one of the wheels is insufficient, the receiver prevents the indicator to indicate the tire pressure until a current wheel position detection finishes.
