Aston Martin TPMS Sensors Explained – By Dan Rosales
We get a lot of questions regarding tire pressure monitoring systems in the Aston Martin vehicles. At TPMS DIRECT we strive to have the most competitive prices and the most accurate information possible. As tire pressure monitoring has become more relevant in day to day use, we will continue to bring you the most up to date information as possible. You are not obligated to buy to sensors from the dealership, we carry the same sensors that are in your vehicle right now so whether your changing to winter tires, or just updating to aftermarket wheels we can get you the sensors that you need.
Aston Martin approached Beru to design more efficient monitoring systems for their vehicles during the Nurburgring 24 hour race. Beru F1 systems TPMS comprises one electronic sensor per wheel, with receiving antennas mounted on the vehicle. The antennas are linked to an ECU which sends data to the driver and pit garages. With data output on a high speed CAN bus, the Aston Martin race cars TPMS is linked to a bespoke display in order to inform the driver of any variance in temperature and pressure, and provide any necessary deflation warnings. In other motorsport applications, it is possible to integrate the system with the car’s existing dashboard.
Aston Martin first approached Beru F1 systems in 2009 to supply its DigiTyre system. With extensive knowledge of system set-up for GT cars, Beru swiftly identified its ‘Lite’ system as the most appropriate for the race cars. This system uses an OE grade ECU, antennas and low frequency (LF) triggers. The company used race specification sensors as a precaution, although logged data later revealed that OE specification sensors would perform to the same level.
The system used on the 2010 cars utilised production specification TPMS hardware, with only software modifications to make it suitable for race use. The LF arrangement is designed to automatically detect which wheel sensor is fitted to each corner of the car. This is said to offer a significant advantage considering the high number of pit stops made per car during the Nurburgring 24 hour race. The automatic learning facility is common to the system now fitted to the roads cars, avoids any manual positioning of wheel sensors, and allows wheels to be fitted to any corner of the car.
