Operator action positioning module for lane assistance function
A blending steering control method includes estimating a handwheel pressure applied by an operator to a handwheel and receiving a handwheel torque input indicating a torque value applied by the operator to the handwheel. The method also includes receiving a target handwheel angle indicating a target handwheel angle of an electronic power steering system configured to control a corresponding vehicle along a defined path. The method also includes generating a scaled operator intent value based on the estimated handwheel pressure and the handwheel torque and generating an output torque value based on the target handwheel angle and scaled operator intent value. The method also includes selectively controlling vehicle trajectory based on the output torque value.
POSITION DETECTION DEVICE
A position detection device includes a first positional sensor mounted on a reference portion, and a second positional sensor mounted on a detection target that is movable relative to the reference portion. A controller calculates a position of the detection target based on a detection value of the first positional sensor and a detection value of the second positional sensor. The position detection device may be applied to a steer-by-wire system for a vehicle. The reference portion may be a fixed portion of the vehicle, and the detection target may be a steering wheel or a vehicle wheel of the vehicle. The controller may calculate a steering angle of the steering wheel or a turning angle of the vehicle wheel as the position of the detection target.
Rotary connector device and method of assembling rotary connector device
A rotary connector device body in which a rotator and a stator are assembled so as to be relatively rotatable has a housing space that can house an FFC inside. The rotary connector device body has a viewing window that is a through hole through which the housing space is viewed from outside of the rotary connector device body, a cover member disposed at the viewing window so as to cover the viewing window, an outer regulating portion facing outside of the rotary connector device body and disposed so as to be able to contact an outer surface of the cover member, and an inner regulating portion facing the housing space and disposed so as to be able to contact an inner surface of the cover member. The cover member is disposed between an outer regulating portion and an inner regulating portion.
Hydraulic steering arrangement
A hydraulic steering arrangement (1) comprising a supply port arrangement having a pressure port and a tank port, a working port arrangement having two working ports (L, R), a mechanical steering unit (3) connected to a steering wheel (2) and being arranged between the supply port arrangement and the working port arrangement (L, R), supply valve means (12) having a connection to the pressure port and to the working port arrangement (L, R) and being controlled by a controller (10), and a steering wheel sensor (9) connected to the controller (10) is described.

Control device for vehicle
A control device for a steer-by-wire type vehicle calculates a target turn angle being represented as a function of a steering angle of a steering wheel, and controls a turning device such that a turn angle of a wheel becomes the target turn angle. A variation range of the steering angle includes: an effective steering range in which the steering angle is an effective maximum steering angle or smaller; and an adjustment steering range in which the steering angle is between the effective maximum steering angle and a predetermined maximum steering angle. The target turn angle calculated according to the effective maximum steering angle is an effective maximum turn angle. The control device variably sets the function according to a road surface condition such that the effective maximum turn angle in a case of a low-μ condition is smaller than that in a case of a high-μ condition.
