Electric vehicles

Electric vehicles (EVs) will only increase this challenge. Fully electric vehicles do not have the support of an additional power source such as ICE. All the energy the vehicle needs is supplied by the energy stored in the batteries. 

As a result, the number and sophistication of an electric vehicle’s electronic components has a direct impact on the vehicle’s range and performance. ADAS systems often include cameras, radar, and ultrasonic sensors that enable lane departure warning systems, automatic braking, and more. 

These systems are constantly draining the battery because they are always active. To increase the efficiency of E/E systems and thus the range of drives, engineers will need to conduct architecture and trade-off analyzes to explore architectural designs. 

Trade-off analyzes for EVs will need to consider hundreds of components and millions of signals while optimizing feature placement, network latency, error rate, and more. In addition, engineers will have to manage the high-voltage lines that transmit power to the electric motor or motors (Figure 1). These lines often require special design guidelines regarding routing and bundling to be considered.
