An automobile architecture includes a composite cable, a main electronic control unit, a subsidiary electronic control unit, a motor sensor, and a wheel velocity sensor. In the architecture, the composite cable connects the main electronic control unit and the subsidiary electronic control unit, and the motor sensor and the wheel velocity sensor are connected to the subsidiary electronic control unit.

Automobile architecture

A wire harness includes a first circuit group and a second circuit group. The first circuit group has one end connected to a first connector and another end connected to a second connector. The second circuit group has one end connected to the first connector and another end connected to a third connector. The second circuit group branches from the first circuit group at a position of the second connector or at a position of a connection target connected by the second connector.

A wire harness is disposed across an interior area and an exterior area, and is connected to a connection target component in the exterior area. The wire harness includes: a water shut-off cable being disposed across a boundary between the interior area and the exterior area, and having inter-wire water shut-off property; and a non-water shut-off cable being connected to the water shut-off cable in the exterior area, and being connectable to the connection target component.

A control apparatus for an electric parking brake, including an electric motor to generate a brake force by contacted friction materials upon a brake request, includes a no-load current detection unit to detect a current with the no-load electric motor; a voltage monitor unit to detect a voltage applied to the electric motor monitored between two points on a power line; a resistance calculation unit to calculate a resistance between two points based on the no-load current and the monitored voltage; a required voltage calculation unit to calculate a required voltage between the two points required for driving the electric motor to generate the brake force based on the resistance and a target current; and a control unit to flow a current over the target current in the electric motor based on a comparison between the required and monitored voltages.
