VNA-Wheel Sensor – Multifunctional rf-wheel-sensor

In today's passenger cars, a large number of sensors are installed which monitor the vehicle condition. For example, since 01.11.2014, all new cars have to be fitted with tire pressure sensors according to the EU regulation. The monitoring of the springs is another very important measuring parameter. This sensor electronics weighs about 40 g and is attached to the wheel housing. The so-called VNA wheel sensor can be used for the following contactless measurements: tire pressure, tire moisture, wheel speed, spring depth, suspension speed, steering angle and foreign body detection.
The VNA wheel sensor consists of a permissible transmitter for a broadband microwave signal (in the microwave range), a vector network analyzer (VNA) and an evaluation unit.
A German and an international patent application were filed, international applications are still possible.
In the name of the University of Applied Sciences Aachen, we offer interested companies the opportunity to license and further develop the technology.
