The Tesla Cybertruck revolutionized the automotive industry with its groundbreaking 48V electrical system and steering-by-wire system. Of course, if the wiring harness does not have a new way of wiring, communication methods do not have a new change, this revolutionary progress is impossible to achieve.   Tesla Motors has recently applied for a patent and is eyeing wiring harnesses. Cybertruck may look a little underwhelming, and it doesn't feel as good as Musk previously said it would.   However, Cybertruck's advanced technology did not disappoint. One of them is the 48V low-voltage electrical system(low-voltage electrical wire harness) used in production vehicles for the first time. By dramatically improving and simplifying the electrical architecture, Tesla will be able to build the next generation of electric vehicles at a better cost.     Tesla has announced that Cybertruck's cabling architecture will be significantly simplified compared to previous Tesla electric vehicles. Tesla achieves this by using multiple local controllers connected to a high-speed communication bus instead of connecting each electrical component to a central controller. To understand this situation, it is necessary to talk about traditional vehicles. Typically, every sensor and electrical component on a vehicle must be connected to a central controller and low-voltage system to obtain power. Sometimes, this means complex parts require a lot of wire. Let's take doors for example. It may contain sensors that signal to the car's computer that the car is on, off, or tilted. The same is true for Windows, which have buttons that trigger opening and closing. These switches are connected to the vehicle's controller, which in turn is connected to the window actuator to lower or raise the glass.   That's when we add speakers, airbags, cameras... You'll understand why the harness is so messy. Wires in modern vehicles extend for many kilometers, adding complexity, cost, and weight. To make matters worse, building and installing them is mostly done by hand. These are expensive and time-consuming processes that Tesla wants to eliminate.   That's why it came up with the idea of a distributed controller. Vehicles will be equipped with many local controllers for various functions, rather than a central unit.   Distributed controller For example, a door controller is responsible for putting Windows, speakers, lights, mirrors, and other components into the electrical input before it can work. In this case, the wires are short and can be fully contained within the door assembly. The doors will then be connected to the vehicle's data bus with just two wires, which also provide power to the electrical components. All the complex functions of a door can be achieved with just two wires, compared to more than a dozen in a conventional car, which is what Tesla has done with the Cybertruck.   The electric pickup uses a steer-by-wire system that requires a...
