Title:
BRAKE DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/091879
Kind Code:
A1
Abstract:
A brake device (11) for a vehicle comprises a front-wheel-side wheel brake (23) to which a braking force is applied by the action of a brake fluid pressure of a hydraulic brake system (25), and a BRK-ECU (17) which performs a pressure regulation control of the brake fluid pressure, on the basis of a target deceleration of a vehicle (10). The BRK-ECU (17) comprises an information acquisition unit (81) for acquiring information related to a brake operation amount and a vehicle body speed of the vehicle (10), and a setting unit (83) for setting a value of the target deceleration. The setting unit (83) variably sets the value of the target deceleration so that the value becomes greater as the brake operation amount increases and as the vehicle body speed increases. With this structure, it is possible to maintain good brake feeling.
