2. 0.13mm2 contract wire quality proportion

In traditional models, most of the signal cables use 0.35mm2 and 0.5mm2 wires. Their quality is 4.5kg /km, 6.5kg/km, and the quality of 0.13mm2 is only 2.0kg/km (0.13mm2 pure copper wires and alloys The quality of the wires is similar), and 0.13mm2 can reach 55%~ 69%of the signal cable. The signal wires of the vehicle low -voltage beam can be roughly divided into Lin, CAN, Ethernet, LVDS, etc. Among them Small. Taking a new energy pure electric SUV as an example, all the entire vehicle LIN network uses a 0.35mm2 wire, the dosage is about 80m, the wire copper weighs about 0.36kg, and the Can network uses 0.35mm2 wires. The amount is roughly 120m. The weight of the wire copper is roughly 0.54kg. If all the above wires are optimized to 0.13mm2 wires, the beam copper weight will be reduced by 0.5kg.

The highly complicated electronic electrical architecture has led to the complex structure of the entire car today and the cost is very high. Even the unsafe of cars is closely related. After the expected future intelligence and popularization, the requirements of the domain controller for data transmission will completely grid the next -generation car to optimize the cable beam of the actuator, sensor, and controller to reduce the length and amount of wire beam. Among them, a new energy pure electric vehicle represented by Tesla, through the practice of integrated controllers, promotes the concept of the Zone Control regional controller, reduces the number of functional controls and actuators, optimizes the connection between the controller and the actuator The amount of wire wires will be reduced, and the cost of the wiring beam is greatly reduced and the length of the vehicle is only about 2400m on the new generation of Model Y models. Taking Volkswagen B -class car as an example, the length of the vehicle is about 5000m, C. C. C. C. C The length of the cable beam is as high as 6000m, and the lightweight results of the wires are obvious. Figure 1 is the evolution of the electronic and electronic architecture divided by Bosch.

In this trend chart, it can be seen that the changes in Domain Control (domain controller) can solve the demand of large bandwidth by setting up multiple master nodes and each master node to solve the demand for large bandwidth. Corresponding to the signal of the actuator and sensor, and then transmitting between the main nodes, it can reduce the communication between the two or two, and it can even completely replace the traditional CAN network.
