KR200196377Y1 - Abs simulator - Google Patents

Abstract

The present invention is a system that can test the failure of electronic control ABS and comprehensively train the system. By simulating and testing the input value of the sensor input to the ABS ECU, the output value of the ABS ECU is checked and at the same time the ABS simulator to check the operation status.

The simulator consists of a control unit and an apparatus unit.

ABS ECU, which reads speed from each wheel speed sensor, calculates this and sends a control signal to solenoid valve in the air motor to control the speed of the wheel to prevent slipping due to lock phenomenon of each wheel. According to this control signal, the pressure of the hydraulic line connected to each wheel is controlled. The pressure of each part is measured by the pressure sensor and displayed on the operating program screen, and the user analyzes and diagnoses the system based on such data. In addition, this simulator has a general-purpose data acquisition control device to ensure easy data acquisition and control so that users can easily analyze the data.

Description

ABS Simulator {ABS SIMULATOR}

The ABS simulator does not exist in the past, but simply lists the names of each part by listing peripheral devices including the ABS device on the panel.

-It should be possible to continuously test the operation of ABS similarly to the actual vehicle condition.

-There are automatic mode inspection and manual mode inspection method, so it should be very convenient for training and room maintenance.

-The operating status of the system can be viewed on the screen based on the time axis as graphs and digital values, and it must be able to precisely analyze the same time axis using the mouse.

-The user should be able to test by editing all test conditions on the screen.

-Data editing and saving function should be very convenient.

-Since all data are shown digitally on the picture screen of a real vehicle, it should be easy to understand educationally and at the same time as the scope status, so it is very convenient to compare and analyze the data on the time axis.

The simulator consists of a control unit 106 and a device unit. The control unit 106 is composed of a personal computer (PC) including an operation program and a universal data acquisition control device 107 for an interface, and the device unit includes a booster cylinder (a master cylinder). 102), the air service unit 103 for filtering moisture in the air, controlling the pneumatic pressure, and lubrication of the booster cylinder; 203, wheel speed controller 204, ABS ECU 205, terminal block 206, air motor 207 as a modulator, pressure sensor 209 for measuring the pressure of each wheel, and the flow of the system The circuit diagram 101 etc. which were described are comprised. In this simulator, the pneumatic service acts as the driver's foot that pushes the piston in the master cylinder during braking.

The present invention was simulated using the principle that ABS works in the vehicle. This simulator is divided into automatic mode and manual mode. In the automatic mode, the user programs the speed diagram of each wheel and performs experiments to substitute the speed of each wheel in the vehicle. At this time, the control device generates a frequency along the programmed speed diagram and inputs it to the ABS ECU 205. The input signal sends a control signal to the solenoid valve 110 in the air motor to control the speed of the wheel to prevent slipping due to lock phenomenon of each wheel through the operation. This control signal controls the pressure of the hydraulic line connected to each wheel. The pressure in each part is measured by the pressure sensor and displayed on the operating program screen, and the user analyzes and diagnoses the system based on such data. In the manual mode, the user operates the wheel speed controller 204 by hand to increase or decrease the speed of each wheel. At this time, the wheel speed sensor 203 senses the speed and sends a signal to the ABS ECU 205. After that, all operations are performed in the automatic mode. Is the same as The speed of each wheel was controlled by using a variable resistor by driving the wheel on the AC motor shaft. At this time, the wheel speed sensor 203 is positioned in four directions of the north, south, east, and west of the wheel to sense the speed.

In addition, this simulator is equipped with a universal data acquisition control device 107 in order to ensure the ease of data acquisition and control to store all the data obtained in the experiment so that the user can easily analyze the data, and all the test environment can be changed arbitrarily by the user And ease of control. It has a user interface function in connection with a personal computer (PC) and invents all experiments to be automatically run in the program for the user interface. All data obtained during the test is displayed as digital and graph values on the screen screen by the user interface program, and user setting and editing functions are provided. Also, the user interface function is enhanced to analyze the data after the test. .

-The operation status of ABS can be continuously tested similarly to the actual vehicle status.

-The speed diagram that ABS can operate is automatically operated by the program and the operating status of each pressure sensor is analyzed.

-Operate the wheel speed manually and analyze the operation status of each pressure sensor.

-All data is displayed digitally on the picture screen of the real vehicle, so it is easy to understand educationally and at the same time, it is very convenient to compare and analyze the data on the time axis.
