[0037] The utility model discloses a cable for a driving assistance system, which combines cables with multiple functions into one cable, so that the whole cable can simultaneously provide different types of signal transmission support and power supply for multiple different components, thereby reducing the workload during cable laying and the space occupied by the cable laying; at the same time, the whole cable has excellent bending resistance and anti-interference performance, can well meet the use requirements of automobiles, and is suitable for practical use.

[0038] Furthermore, the first conductor 111, the second conductor 121 and the third conductor 131 are all formed by twisting a plurality of tinned copper wires. Compared with common conductors, conductors twisted with tinned copper wires have higher oxidation resistance.
