Abstract
Disclosed is a method of monitoring tire pressure monitoring systems in a motor vehicle. The motor vehicle has a tire pressure monitoring system with indirect measurement which detects tire inflation pressure loss on the basis of wheel speed data, and a tire pressure monitoring system with direct measurement (TPMS) which detects tire inflation pressure loss from tire inflation pressure values measured directly by pressure modules on the vehicle tire. According to the method a warning relating to tire inflation pressure loss emitted by a pressure module of the tire pressure monitoring system with direct measurement (TPMS) is not transmitted to the driver until this tire inflation pressure loss is confirmed by the tire pressure monitoring system with indirect measurement or by all pressure modules that are still working in fail-free manner. Also disclosed is a computer program product.
