The indirect-measuring tyre pressure monitoring system is also referred to as a "Deflation Detection System (DDS)".

The DDS uses the data from the ABS speed sensors and recognises the various rolling circumferences.

Monitoring, reporting and the display of air-pressure loss are controlled by software.

DDS does not require additional sensors. There is thus no danger of damaging sensors during demounting/mounting of the tyres.

Vehicle manufacturers integrate DDS when designing the system.
