Embodiment Construction

[0035] Embodiments of the controller proposed by the present invention will be described below in conjunction with the accompanying drawings.

[0036] figure 1 It is the circuit schematic diagram of the controller proposed according to the present invention, and it is a controller of a modulating braking system of a two-wheeled motorcycle. [U1] in the figure is a single-chip microcomputer P87LPC767, and its OTP EPROM has written a control program, which includes various control methods mentioned above. [U2] is the acceleration sensor ADXL202AE, and the acceleration signal is sent to the single-chip microcomputer by pins 4 and 5. [J1] and [J2] are the control relays of the front and rear wheel modulating brakes respectively; the braking resistor [W1] is an adjustable resistor, and its resistance value is related to the angle of the brake pedal, indicating the braking strength. It forms a voltage divider circuit with the bias resistor [R1], and its voltage is converted into a ...

Abstract

A control method for the brake system of car or motorcycle, especially the PWM-type brake system, is based on the acceleration detection. It can realize the total mass (weight) detection, ground sticking coefficient detection, dynamic load distribution, optimal slide rate control and anti-seizing function. Its controller is also disclosed. Its advantages are simple structure and low cost.

Description

Technical field [0001] The present invention relates to a control method and a control device of a braking system of a motor vehicle, in particular to a control method and a control device for a modulated braking system of an automobile and a motorcycle, and having characteristics such as anti-lock braking and dynamic load adjustment. . Background technique [0002] The existing braking systems all work in an analog mode, that is, the braking force and control force are continuously changing, and it is difficult to realize automatic control. There are two types of automatic control systems - anti-lock braking system (ABS) and electronically controlled braking system (EBS). complex structure. [0003] Chinese patent 02122371.8 proposes a modulated anti-lock braking system, which is based on open-loop control and has a simple structure, but is not yet perfect. The applicant later proposed a modulated braking system, the basic principle of which is pulse width modulation, th...
