Problems solved by technology

In such a case, the recovery of the wheel speed of the target wheel becomes slow, and the pressure increase control is executed before the wheel speed of the target wheel is fully recovered, thereby possibly destabilizing the behavior of the straddle-type vehicle.

Embodiment Construction

[0018] Hereinafter, the control device of the present invention will be described with reference to the drawings. In addition, the control device used for two-wheeled motorcycles is described below, but the control device of the present invention can also be used for straddle-type vehicles other than two-wheeled motorcycles (for example, three-wheeled motorcycles, all-terrain vehicles, etc.) vehicles, bicycles, etc.). In addition, a straddle type vehicle means a vehicle in which a rider rides astride, and includes scooters and the like.

[0019] In addition, the configuration, operation, etc. described below are examples, and the control device and control method of the present invention are not limited to such configurations, operations, and the like.

[0020] In addition, below, the same or similar descriptions will be appropriately simplified or omitted. In addition, in each figure, the reference numerals are omitted or the same reference numerals are attached to the same...

Abstract

The invention provides a control device and a control method capable of appropriately stabilizing the action of a straddle-type vehicle. In this control device and control method, during execution of a control flow in which pressure reduction control for reducing the brake fluid pressure of a target wheel, fluid pressure holding control for holding the brake fluid pressure, and pressure increase control for increasing the brake fluid pressure are continuously executed in this order, the control flow is controlled on the basis of the wheel speed of the target wheel. It is determined whether or not to execute a mode for transitioning from the hydraulic pressure holding control to the pressure reduction control or a mode for prohibiting transitioning from the hydraulic pressure holding control to the pressure increase control.

Description

technical field [0001] This application relates to a control device and a control method capable of appropriately stabilizing the behavior of a straddle-type vehicle. Background technique [0002] Conventionally, as a control device that controls the behavior of a straddle-type vehicle such as a motorcycle, there is a control device capable of performing anti-lock brake control. In the anti-lock brake control, for example, as disclosed in Patent Document 1, when the slip ratio of the target wheel (that is, the wheel to be controlled by the brake fluid pressure) becomes larger than the allowable slip ratio , the depressurization control for reducing the brake hydraulic pressure of the target wheel is performed. As a result, the wheel speed of the dropped target wheel can be increased (that is, recovered), so that the target wheel can be suppressed from locking. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2018-024324. [0004] However, in the field of antilock...
