PSA Peugeot-Citroën, one of the most important European car producers, has chosen TTP as its reference protocol for fault tolerant communications for by-wire prototypes.

PSA Peugeot Citroën always delivered leading edge technology products and wants to be among the first car makers offering by-wire technology to its customers. Electronics will assist the driver and can provide the means for enhanced response characteristics, far beyond what a driver is capable of when encountering a hazardous driving situation, thus vastly improving active safety and reducing risk of injury to the vehicle and it's occupants.

"During the last months, we came to the conclusion that TTP is a proven technology, available to industry able to address all our needs in the field of reliable communications", said Denis Chapuis, responsible for PSA's by-wire project. "We believe that TTP is today the right solution for our short and mid term needs, even though our group will look attentively at each evolution of the market."

Safety and reliability as well as high speed capability were the most important factors leading to the selection of TTP. Already widespread and growing among the aerospace industry, TTP passed the most stringent tests and complies with the highest safety standards. The availability of chips through silicon suppliers was also paramount.

"PSA Peugeot-Citroën is one of the most innovative car makers world wide. Their decision to select TTP as their reference protocol for in-car electronic communication system related to mechanical systems requiring high safety standards, is another milestone for TTP to become the standard in the automotive industry", said Dr Stefan Poledna, CEO of TTTech.

PSA Peugeot Citroën and TTTech intend to work closely together and with others, to improve TTP and always better tailor the protocol to the needs of the car makers.
