Introduction 

The customer, a Chinese vehicle manufacturer, is in the process of developing a new type of vehicle. They want to make some tests for their new brake system in the brake test bed. They want to measure the brake line pressure values of four wheels when they brake at different speeds.

Measurement setup

DATA ACQUISITION SYSTEM

SENSORS

  • Kistler CPFTA (Brake Force Sensor)
  • Kistler WP-500 (Brake Displacement Sensor)
  • KELLER 21Y (Brake Line Pressure)

SOFTWARE

The brake line pressure sensors and the brake force sensor have been installed and connected to the analog input channels of the DEWE-43 data acquisition system.

Analysis

The testing engineers chose the measured value that they focus on, and put them in the measure view.

Here we can see the brake line pressure value of the four wheels (FL, FR, RL, RR), the brake pedal force and displacement.
