The right architectural solution for innovative vehicles

The automobile industry is now threatened by new consumption habits of and the emergence of mobility services. Added to these new challenges are those of vehicle electrification, autonomous driving systems and robotic taxis.

Car technology is rapidly increasing and therefore automotive manufacturers are adding more and more computer-based systems, applications and connections. The cost of electronics and wiring harnesses to support them in terms of cabling, network interfaces, and onboard computing power is growing.

Today, each vehicle component typically has its own dedicated wiring and communication requirements. There are multiple proprietary standards for communication in a car, including analog signals on wires, CAN, FlexRay, MOST and LVDS. Due to this complex cabling, the wiring harness is the 3rd highest cost component in a car (after the engine and chassis). Harnesses are built one at a time, and comprise 50% of the cost of labor for the entire car. The wiring harness is also the 3rd heaviest component (behind the chassis and engine). Moreover, any technology that reduces this weight directly contributes to fuel economy.

 

Analysts identify that by 2020:

• 40% of the cost of a car will be in electronics (up from about 32% today). New safety, infotainment, and communication features and technologies will drive this increase.

• Automotive wiring harnesses will change from heterogeneous networks of proprietary protocols (such as CAN and MOST) to hierarchical homogenous automotive Ethernet networks.

In this context, EtherFly is addressing the following use:

• Low End-to-End Latency applications (< 10 us requirement) that are:

• Chassis management
• Power train management

Network Backbone of the car. This backbone aims to interconnect various sub-networks with different protocols and/or operating speeds and especially for the needs of the near autonomous car.
