[0061] The structural configuration of the wiring wiring structure of the first embodiment is now explained.

[0062] 【System structure of composite vehicle】

[0063] figure 1 is a schematic block diagram showing a drive system of a compound vehicle (as one example of a vehicle) employing the wiring wiring structure of the first embodiment. like figure 1 As shown, the drive system of the compound vehicle in the first embodiment includes an engine E, a first motor / generator MG1, a second motor / generator MG2, an output sprocket (output sprocket) OS, a power (torque) distribution mechanism TM and Electric compressor unit (electric auxiliary unit) A / CON.

[0064] The engine E is a gasoline engine or a diesel engine. The valve opening degree and the like of the throttle valve of the engine E are adjusted in accordance with control commands from the engine controller 1 as described below.

[0065] Each of the first motor / generator MG1 and the second motor / generator MG2 is a syn...

Abstract

A high-voltage harness routing structure includes: a subframe; a driving power unit; an electric power distribution unit; an electrical auxiliary unit arranged to cause the driving power unit to be sandwiched between the electric power distribution unit and the electrical auxiliary unit; and a high voltage harness connecting the electric power distribution unit with the electrical auxiliary unit in a routing path. In this routing path, the high voltage harness drops from the electric power distribution unit toward the subframe and then extends along the subframe in a vehicle-width direction. The high-voltage harness routing structure further includes a driving power unit mount including a mount main body arranged apart from the subframe to form a space between the mount main body and the subframe; and a protector that covers at least a high-voltage harness's portion extending along the subframe in the vehicle-width direction and interfering with the driving power unit mount. The high voltage harness covered by the protector is passed through the space.

Description

technical field [0001] The present invention relates to a wiring wiring structure for a vehicle in which a power distribution unit and an electric auxiliary unit installed to sandwich a drive power unit are connected to each other via high-voltage wiring. Background technique [0002] Internet website, TOYOTA home page > Demo room > Alphard hybrid > Function. Mechanism > Hybrid system (URL: http: / / toyota.jp / alphardhybrid / dynamism / hybrid / index.html) (online on October 5, 2005 Inquiry), discloses a previously proposed high-voltage wiring wiring structure for a compound vehicle in which a power control unit (inverter) sandwiching a compound power unit and an electric compressor are connected to each other via high-voltage wiring , the power control unit (inverter) is arranged at the upper position of one end side of the compound power unit equipped with a transverse engine and motor / generator, and the electric compressor is arranged at the front of the other end sid...
