Problems solved by technology

[0006] 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 driver's point of view, when the control of the hydrostat is continued from this state, it is not preferable that the controlled hydrostat suddenly increases the pressure to compensate for the aforementioned difference.

Embodiment Construction

[0050] Hereinafter, an embodiment of the present invention will be explained with reference to the accompanying drawings.

[0051] FIG. 1 is a hydraulic circuit diagram of a motorcycle braking device according to an embodiment of the present invention. In the braking device of the present embodiment, the front-wheel-side brake circuit 1a and the rear-wheel brake circuit 1b, which are independent of each other, are connected together by one controller (ECU) 20 .

[0052] In the front wheel side brake circuit 1a, a brake lever as the brake operating portion 2 performs a braking operation, and in the rear wheel side brake circuit 1b, a brake pedal as the brake operating portion 2 is performed a braking operation. The other components are basically the same in the brake circuit 1a on the front wheel side and the brake circuit 1b on the rear wheel side. Therefore, only the brake circuit 1a on the front wheel side will be described in detail, while the parts of the brake circuit 1...

Abstract

A braking device for a motorcycle for controlling a sudden increase in the braking force caused by a time lag from the time the amount of operation of a brake operating portion is detected until a change in hydraulic pressure of wheel braking means for improving the feel of braking. An input-side pressure sensor detects a master cylinder pressure and a hydraulic modulator creates a hydraulic pressure to be exerted on a brake caliper. A controller is provided for controlling the hydraulic pressure created by the hydraulic modulator in accordance with a detected signal provided from the input-side pressure sensor. In accordance with a change in the quantity per unit time of the detected signal provided from the input-side pressure sensor the controller limits a change speed of the hydraulic pressure created by the hydraulic modulator.

Description

[0001] This application is a divisional application of an application with an application date of December 20, 2005, an application number of 200510023042.8, and the title of "braking device for motorcycles". technical field [0002] The present application relates to a braking device for motorcycles, and more particularly to a so-called brake-by-wire braking device. Background technique [0003] A brake-by-wire device for motorcycles is known, in which the operation amount of a brake operating portion such as a brake lever is detected electrically, and the operation of the wheel brake device is generated based on the detected value using a hydraulic regulator hydraulic to achieve. For example, see JP-A 310717 / 2001. [0004] 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 applying braking force to the wheel by hydraulic operation, which are The main brake pas...
