Problems solved by technology
Therefore, when the electric power steering device is mounted on the vehicle, there is a possibility that the electric power steering device interferes with other components.
[0011] In addition, in the electric power steering devices described in Patent Documents 2 and 3, an electric motor with brushes is used as the electric motor, and no rotation position detection sensor is provided.
[0012] On the other hand, when connecting the wiring of the rotational position detection sensor and the like to the control device via the wiring outside the housing, wiring components for the external wiring are required, and are easily affected by radio noise due to the long path length.

Embodiment Construction
[0042] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
[0043] figure 1 It is a schematic diagram showing a schematic configuration of an electric power steering device 1 as a vehicle steering device according to an embodiment of the present invention.
[0044] Reference figure 1 , The electric power steering device 1 includes: a steering wheel 2 as a steering member; a steering mechanism 4 that is linked to the rotation of the steering wheel 2 to steer the steering wheel 3; and a steering assist mechanism 5, the steering assist mechanism 5 is used to assist the driver's steering. The steering wheel 2 and the steering mechanism 4 are mechanically connected via a steering shaft 6 and an intermediate shaft 7.
[0045] In this embodiment, an example in which the steering assist mechanism 5 provides an assist force (steering assist force) to the steering shaft 6 will be described. However, the present invention can also b...

An electric power steering apparatus (1) comprises a control device (12), which controls driving of an electric motor (18) based on the detection signals from a rotational position-detecting sensor (72; 72A), which detects the rotational position of the rotor (64) of the electric motor (18), and a steering status detecting sensor (11; 11A). The control device (12) is housed in a housing (100) that is partitioned by a first housing (23), which is at least a portion of the motor housing (25) for the electric motor (18), and a second housing (24; 24A; 24B) that touches the first housing (23). At least one of the rotational position-detecting sensor (72; 72A) and steering state detecting sensor (11; 11A) is connected to the control device (12) by means of only a signal wire (81; 134) inside the first housing (23) or the second housing (24; 24A; 24B).
Description
Technical field [0001] The invention relates to a steering device for a vehicle and a manufacturing method thereof. Background technique [0002] An electric power steering device as a steering device for a vehicle uses an electric motor to assist the driver in steering. That is, by detecting the steering state of the steering member using various sensors and the like, and the control device controls the electric motor based on the detection result of the steering state and the like, thereby imparting a steering assist force to the steering mechanism. [0003] It has been proposed to arrange the control device between the electric motor and the reduction mechanism in the axial direction of the electric motor (for example, refer to Patent Documents 1 to 3). [0004] In the electric power steering device of Patent Document 1, a circuit housing different from the two housings is provided between the motor housing of the electric motor and the gear housing of the reduction mechanism, an...
