Haldex Licenses CVDC Slip-control Braking Technology

last modified Mar 31, 2018 01:29 PM

CVDC Member Haldex Brake Products recently signed a license agreement with the University of Cambridge to exploit the CVDC's slip-control pneumatic braking technology for truck brakes.

Haldex is developing the technology and has prototypes running on test tracks.

An interesting article was published by Reuters this week, discussing the recent takeover bids for Haldex.  The last third of the article discusses the slip control braking technology.  "One of the main projects that Haldex is pursuing is an electronic brake system (EBS) based on intelligent braking valves mounted on each wheel, as opposed to the standard of a central brake control unit...."

Testing the CVDC's slip-control braking system on the straight line wet grip track at MIRA

The CVDC's slip-control braking system has been featured on the BBC.  Richard Westcott, the BBC's Transport Correspondent filmed the system during braking tests at the MIRA proving ground in Nuneaton on 15th May 2015.

In back-to-back tests, the stopping distance for the CVDC slip-control system was 19% less than for the conventional ABS.  This is very close to the theoretically shortest possible distance with these particular tyres.

Slip Control Braking Vehicle Tests Completed

last modified Nov 06, 2013 11:05 AM
Researchers in the CVDC recently completed the first set of full scale straight-line braking tests on the CVDC's new slip control braking system.

The team was led by Leon Henderson and the work was performed in collaboration with Haldex Brake Products Ltd.  The CVDC's tri-axle semitrailer was fitted with the new system and tested on a range of low friction surfaces at the MIRA vehicle testing facility near Nuneaton, UK.  The measurements compared the emergency braking performance of the CVDC’s slip control braking system and a commercially available antilock braking system (ABS) for heavy goods vehicle (HGVs). Results showed that stopping distances could, on average, be reduced by 16% using the new system. Air use was also reduced by 50%; providing scope to potentially use smaller air reservoirs on HGVs. A short video showing the emergency braking performance of the two systems’ on a surface with friction properties similar to ice can be seen on Youtube ( Further HGV braking trials using the new system are being planned for 2014, when it is hoped to obtain even better stopping performance. More information about the technology can be found at:

During the September 2012 Consortium meeting in Gothenburg, Sweden, the CVDC was presented with a new FH12 tractor unit by the hosts, Volvo Trucks.

On receiving the new tractor unit, Professor David Cebon, Director of CVDC, remarked: "The type of work we do in the CVDC is critically dependent on having the capability to do full scale testing of heavy vehicles.  We are indebted to Volvo for their generous gift which will allow us to continue this work for the foreseeable future."

The Volvo tractor unit was shipped to its new home near Cambridge in early November, where the research team has begun instrumenting and equipping it for its new role as research work-horse.

Volvo Trucks has been a key member of the CVDC since 1996, and donated a red FH12 tractor unit in 2000.  In its more than 10 years’ service, the red tractor has played a pivotal role in many of the CVDC’s research projects, including semi-active suspensionactive roll control; and active trailer steering.  Currently, researchers in the CVDC are investigating a number of aspects for heavy goods vehicles, innovating in: advanced ABS systems, regenerative braking, autonomous reversing, accident avoidance and use of long combination vehicles off-highway.  The new truck will be pressed into service on all of these projects.  The overall aim is to make heavy goods vehicles safer, more economical, and more fuel efficient.
