The invention discloses a vehicle wire harness assembly based on wheel speed sensing. The vehicle wire harness assembly comprises a signal wire body. The two ends of the signal line body are electrically connected with a wheel speed sensor and a matching interface respectively. The outer side of the signal line body is coated with a silica gel isolation layer, and a first cavity is formed between the silica gel isolation layer and the signal line body; the outer side of the silica gel isolating layer is coated with an outer rubber layer; isolation ridges are uniformly distributed on the outer wall of the silica gel isolation layer in the circumferential direction, and the space formed between the silica gel isolation layer and the outer rubber layer is divided into a plurality of second cavities by the isolation ridges; the second chamber is communicated with the first chamber; an electric heating wire spirally wound on the outer wall of the signal line body is further arranged in the first cavity, and the first cavity and the second cavity are both filled with heat conduction liquid; a temperature sensor is arranged on the matching interface; by arranging the temperature sensor, the electric heating wire and the heat conduction liquid, the outer rubber layer is heated, the situation that the temperature of the wire harness is too low, and consequently the wire harness is broken is prevented, and the structural reliability is higher.
