Braking device for motorcycle

Abstract

A motorcycle brake device for controlling sudden increase of braking force caused by a time delay from the detection of the operation amount of the brake operation part to the change of the hydraulic pressure of the wheel brake device, so as to improve the braking feeling. An input side pressure sensor detects the pressure of the master cylinder, and a hydraulic regulator generates the hydraulic pressure applied to the brake calipers. A controller is used to control the hydraulic pressure generated by the hydraulic regulator according to the detection signal provided by the pressure sensor on the input side. The controller limits the change speed of the hydraulic pressure generated by the hydraulic regulator according to the change amount per unit time of the detection signal provided by the pressure sensor on the input side.

Description

technical field [0001] The present application relates to a braking device for motorcycles, more particularly to a so-called brake-by-wire braking device. Background technique [0002] A brake-by-wire device for a motorcycle is known in which the operation amount of a brake operating portion such as a brake lever is electrically detected, and the operation of the wheel brake device is generated based on the detected value using a hydraulic regulator. achieved by hydraulic pressure. For example, see JP-A 310717 / 2001. [0003] A brake-by-wire device is known in which a master cylinder is interlocked with a brake lever (brake operating portion) and a brake caliper (wheel brake device) for hydraulically operating a braking force on a wheel, which are set The main brake passages with normally open first electromagnetic switch valves are connected together. The hydraulic regulator is used to supply the hydraulic pressure generated by the electric actuator to the brake caliper, ...

AI Technical Summary

Problems solved by technology

[0005] However, in this brake device, there may occur a time delay from the detection of the operation amount of the brake operating portion to the change of the hydraulic pressure of the wheel brake device.

Therefore, when the time delay increases, when the hydrostat is controlled based on the operation amount of the brake operation portion, the actual operation amount of the brake operation portion further increases, resulting in the target control pressure of the hydrostat and the wheel brake The difference between the actual brake pressure of the device increases

Therefore, from the point of view of the driver's perception, when the control of the hydrostat continues from this state, it is not preferable that the controlled hydrostat suddenly increases the pressure to compensate for the aforementioned difference.
