Document Type and Number:
WIPO Patent Application WO/2023/167295
Kind Code:
A1
Abstract:
[Problem] The objective of the present invention is to achieve a cost reduction by adopting a configuration in which brake hold control can be implemented without providing a hydraulic unit for a driving wheel. [Solution] This brake fluid pressure control device for a bar handle vehicle comprises: a driving wheel side brake for braking a driving wheel; a driven wheel side brake for braking a driven wheel; a hydraulic unit for increasing, holding, and reducing a hydraulic pressure of the driven wheel side brake; and a control portion for controlling the hydraulic unit. The control portion executes brake hold control including: determining whether the bar handle vehicle is stopped (S1); and, if it is determined that a condition for maintaining the vehicle stop is satisfied (S2: Yes), performing pressure increase control (S3) to increase the hydraulic pressure of the driven wheel side brake, and holding control (S5) to hold the hydraulic pressure of the driven wheel side brake.
