In modern cars, there are many wire harnesses, and the electronic
control system has a close relationship with the wire harness.
Someone once made a figurative analogy: if the functions of the
microcomputer, the sensor and the actuator are compared with the
human body, it can be said that the microcomputer is equivalent to
the human brain, the sensor is equivalent to the sensory organ, and
the actuator is equivalent to the motor organ, then the harness is
the nerve and blood vessel.
The automobile harness is the main body of the automobile circuit
network. It connects the electrical and electronic components of
the automobile and makes them function. Without the harness, there
is no automobile circuit. At present, no matter whether it is a
high-class luxury car or an economical ordinary car, the wiring
harness is basically composed of wires, connectors and wrapping
tapes. It not only ensures the transmission of electrical signals,
but also ensures the reliability of the connecting circuit,
supplies the specified current value to the electronic and
electrical components, prevents electromagnetic interference to the
surrounding circuits, and eliminates the short circuit of
electrical appliances.
In terms of function, the automobile harness has two types: the
power line that carries the power of the driving actuator
(actuator) and the signal line that transmits the input command of
the sensor. The power line is a thick wire that carries a large
current, and the signal line is a thin wire that does not carry
power (optical fiber communication); For example, the
cross-sectional area of the wire for the signal circuit is 0.3 and
0.5 mm2.
The cross-sectional area of the wire for the motor and the actuator
is 0.85 and 1.25mm2, while the cross-sectional area of the wire for
the power circuit is 2, 3 and 5mm2; The special circuits (starter,
alternator, engine grounding wire, etc.) have different
specifications of 8, 10, 15 and 20mm2. The larger the
cross-sectional area of the conductor, the larger the current
capacity. In addition to considering the electrical performance,
the selection of wires is also restricted by the physical
performance when on-board, so the selection range is wide. For
example, the wire between the frequently opened / closed door of a
taxi and the vehicle body should be composed of wires with good
bending performance. The wires used at high temperature positions
are generally covered with vinyl chloride and polyethylene with
good insulation and heat resistance. In recent years,
electromagnetic shielding wires used in weak signal circuits are
also increasing.
With the increase of automobile functions and the universal
application of electronic control technology, there are more and
more electrical components and wires. The number of circuits and
power consumption on the automobile increase significantly, and the
wire harness becomes thicker and heavier. This is a big problem
that needs to be solved. How to make a large number of wire
harnesses more effectively and reasonably arranged in the limited
automobile space, so that the automobile wire harness can play a
greater role, has become a problem faced by the automobile
manufacturing industry.
