AEB in Electric Vehicles Test

This application note on Automatic Emergency Braking AEB in Electric Vehicles Test was kindly provided by our valued suppliers DEWESoft. For more information, contact us.

Dewesoft’s customer, a new manufacturer of Electric Vehicles, needs to validate the performance of ADAS (Advanced Driver Assistance System) functions of their products. Automatic Emergency Braking (AEB) test was performed according to the GB/T 33577-2017 standard. Dewesoft did the tests below.

  • Record the AEB’s commands via CAN & video and display them live during testing
  • Constantly measure the distance between subject Vehicle and the target vehicle
  • Stationary POV test. This test evaluates the ability of the FCW function to detect a stopped lead vehicle. In order to pass the test, the FCW alert must be issued when the time-to-collision (TTC) is at least 2.1 seconds.

The subject vehicle with DS-IMU2 inertial measurement unit:


The front vehicle with DS-VGPS-HSC:

AEB test setup

Dewesoft setup CAN, video, DS-IMU2, and DS-VGPS-HSC at their Head Office. They need to configure the Subject vehicle, the Front vehicle and the route in the Polygon plugin. Clearance and TTC can be calculated by polygon and math function.

Measurement/analysis

When the customer did the test, he could see important parameters (velocity, clearance, TTC and so on) online clearly. When the customer finished the test, he was able to see more details. Everything is recorded synchronously.

Conclusion

The whole measurement took less than one day. Dewesoft installed all the devices and sensors in the morning. The customer’s Electric Vehicle could pass the test, but we couldn’t get all AEB data from the CAN port, because the manufacturer didn’t output all parameters. However, the customer was satisfied with fast installation, easy setup and powerful online data processing.
