UNECE WP.29 regulations for automotive cybersecurity

The first-ever regulation requiring vehicle type approval with regards to cybersecurity. Are you prepared?

In June 2020, the United Nations (UN) officially adopted two new regulations regarding automotive cybersecurity. Set out by UNECE WP.29, UN R155 mandates an automotive cybersecurity management system (CSMS), while UN R156 requires a software update management system (SUMS) for all vehicles. As mandatory requirements for vehicle type approval, the regulations affect the production of every single vehicle across the globe.

From OEMs, Tier-1 suppliers, all the way to software providers – everyone needs to be prepared.

Although many may think that “WP.29” refers to the newer regulations released in 2020, WP.29 is originally a ”Working Party on the Construction of Vehicles” that was established in 1952. It became officially known as WP.29 in March 2000 and the objective has always been to initiate and pursue actions for worldwide harmony in terms of the development of regulations for vehicles. The Working Party is the largest international vehicle regulatory system in the world.

While WP.29 has several working regulations for vehicles, the two regulations released in June 2020 are the first regulations that mandate cybersecurity for connected and autonomous vehicles, signaling the growing importance of securing intelligent transport systems.
