Challenges with Introduction of X-by-Wire Technologies to Passenger Vehicles and Light Trucks with Respect to Functional Safety, Cybersecurity and Availability
Classical vehicle production had over a long period limitation in bringing the driving commands to the actuators for vehicle motion (Engine, Steering, Braking). Steering columns, hydraulic tubes or steel cables needed to be placed between driver and actuator. Change begun with introduction of e-gas systems. Mechanical cables were replaced by thin electric signal wires. For addressing the steering and braking systems, the technical solutions and legal standardizations were not given at this point of time. Nowadays the OEM are starting huge EE-Architecture transformation for manifold reasons and they have the chance to get rid of long hydraulic tubes for braking and solid metal columns for steering. X-by-wire is the keyword, also driven by the plans for higher AD (Autonomous Driving) levels for automated driving vehicles. Driven by new requirement (AD) it also offers new opportunities to design the vehicle in-cabin room.
