Abstract

There are two visible trends that can be observed in the automotive industry that have a big impact on the steering system. The first is the development towards automated driving. Up to level 2 of the SAE Standard (see figure 1), the required steering functionality can be offered by a standard EPS system. However, from level 3 onwards where the driver can be taken out of the loop, the standard EPS system is not sufficient anymore. In that case, a full redundancy of the steering system is required to guarantee full functionality at all times. The second trend, which is not independent of the first one, is the development towards Steer by Wire (SbW) systems. It has always been clear that SbW would be the next logical step in the development of new steering systems. However, the technical challenges and the costs of such a system are quite high when weighed against the direct customer benefits. The trend towards automated driving however is a new driver for SbW systems. A redundant SbW system is the only solution to be able to develop complete new interior concepts and HMI’s for automated driving vehicles.
