Abstract

A tire pressure monitoring unit includes a pressure sensor, a temperature sensor, a transmitter for wireless transmission of pressure and temperature data HF signals, a receiver for receiving wireless control LF signals, a microcontroller containing a program memory and a data storage device containing a library of control programs to control the measurement and transmission activity of the tire pressure monitoring unit. The microcontroller selects from this library, on the basis of control signals that are received, a control program and then writing it into its program memory. When a loading program is activated by a control signal, it causes the microcontroller to transfer into the data storage device an additional control program that is received by the receiver. A method includes adding, to a library of control programs in a data storage device connected to a microcontroller of a tire pressure monitoring unit, an additional control program.
