Wiring harnesses are already heavy, complex and costly, so what happens when AV equipment is added? Two experts weigh in.
Engineers and product planners are already grappling with the complexity of autonomous vehicles (AVs), with the prospect of complexity increasing. Every second, AVs manage advanced-sensor fusion via high-bandwidth networks, while onboard computers run AI algorithms to process gigabits of data. Connecting it all is the wiring harness, which has become increasingly heavy, more expensive and more difficult to package within the vehicle.
Premium-segment cars and full-size trucks can contain 40 different harnesses comprised of 700 connectors and more than 3,000 wires. Stretched in a continuous line, these wires would span 2.5 mi (4 km) and weigh approximately 132 lb. (60 kg). In addition, there can be more than 70 specialty cables that include coax, high-speed data and USB runs.

Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
