Electrical two-wire cables in measure and simulation plus their impact on FlexRay™ timing properties

Since 20 years at least modern passenger cars require technologies to broadcast local acquired data. The most popular communication media are electrical two-wire cables. Examples are shielded, unshielded, coated or uncoated twisted pair cables. Baseband modulating communication protocols like CAN and FlexRay™ are used mostly. The paper points out two aspects of serial communication in cars when using two-wire cables: on one hand typical bit-shape distortions appearing in time-domain measures and simulations; on the other hand the effect of these bit-shapes to a dedicated FlexRay™ timing parameter.
