Abstract
Official abstract text for this publication.
Disclosed is a steering control device capable of adjusting reference points of a plurality of motions, which are used for a steering operation in a steering operating unit, with high precision. In the steering control device, a control unit performs N-point learning under the condition that the absolute value of an operating amount in operation systems other than a target is smaller than a predetermined value (or substantially 0). This makes it possible to suppress the influence of operation systems other than the target on the steering of a vehicle M during N-point learning, making it possible to learn the N point in the operation system of the target with high precision. With this N-point learning for each target, even in an operation system which can be steered through a plurality of motions, it is possible to learn the N point of each motion with high precision.
First claim
Opening claim text (preview).
The invention claimed is: 1. A steering control device comprising: a steering operating unit arranged to be steered through a plurality of different steering motions; and a control unit which performs steering control of a vehicle through a plurality of steering operation systems corresponding to the plurality of steering motions on a basis of an input value input by each of the plurality of steering motions, wherein, when adjusting a reference point of a steering motion in at…
