Weak signal lines such as sensors are not routed in parallel with the power lines and ground lines of high-power inductive loads, and similar designs must be advanced to the vehicle topology design stage.
Weak signal lines should be routed in parallel with power lines and ground lines of high-power inductive loads as much as possible. If it is unavoidable, the anti-interference ability of weak-signal electrical appliances needs to be enhanced.
The high-voltage line and the low-voltage line should be arranged separately, and should be arranged vertically and intersected as much as possible when they must be close to each other.
