In this paper, we use Anti-lock braking system test and simulation platform for the establishment of Hall Sensor wheel speed, vehicle speed sensors, and Strain Gauge to measure braking force. We return the measured data through the signal acquisition card (DAQ) to LabVIEW for interpretation and timely send signals to start the control valve generating the maximum braking coefficient between the wheel and the brake to analyze whether the slip ratio is over 0.2. If the slip ratio is larger than 0.2, the operation of the solenoid valve turns on immediately, and then it produces the shortest stopping distance and sets the slip ratio at around 0.2 in the vicinity of the function to prevent slipping. When the deadlock situation occurs on the locomotive, ABS braking system will intervene the original braking system releasing the pressure of the brake. Then make the deadlocked locomotive brake to be released, so that the wheels restore rolling and we regain the ability to control the locomotive. Later on, brake pressure will resume so that the vehicle continue to slow down.
First, we design a stepping motor which is suitable for motorcycles in the indoor test of hydraulic anti-lock brake module to enable the ABS module-body aircraft ABS miniaturization and simplification of the system testing and simulation platform design direction. In this paper, we focus on motorcycle ABS system performance testing and simulation platform, and then build an experiment for testing on real time hardware and software simulation.
