Volvo Demonstrates AEB Efficiency on FH 18-Wheeler [Video]
Still, back to the first part of the paragraph, regarding weight. A fully-laden 18-wheeler can weigh twenty times as much as a fully-laden sedan, reaching around 40 tons. However, Volvo being Volvo, they have fitted the AEB system to their new line of FH trucks as well.
They recently posted a video showing off how the technology can stop a huge and very heavy truck very efficiently, with no input from the driver whatsoever. They took one of their FH trucks, hitched a trailer on the back, and loaded it with ballast, to reach the 40-ton weight.
This time, unlike the S60’s AEB press test, the system does not fail.
