Ricardo develops ABS and ESC system for US Army’s HMMWVs to improve safety


Ricardo has developed a new antilock braking (ABS) and electronic stability control (ESC) system for the US Army’s high-mobility multipurpose wheeled vehicle (HMMWV) to significantly improve occupant safety.

In 2014, Ricardo started working on a project to modify a fleet of ten HMMWVs belonging to the Michigan National Guard in response to a National Highway Traffic Safety Administration (NHTSA) report.

The HMMWV Rollover Mitigation project aimed to improve the safety, serviceability and agility of HMMWV, which is a core element of the US Army’s vehicle fleet.

"The NHTSA report found a 74% reduction in vehicle rollover since the 2011 mandate of ABS and ESC systems on all passenger vehicles in the US."

Incorporating the same commercial automotive components cited in the NHSTA report, the Ricardo system has been designed to improve HMMWV handling and vehicle stability at a low cost.

The system, which has successfully completed field testing on a number of vehicles, includes antilock braking, electronic stability control, active rollover protection, traction control, and improved brake calipers, pads and rotors.

It also provides shorter stopping distances, reduced wear of brake system components, and increased reliability and operational readiness.

Ricardo Defense Systems president Chet Gryczan said: “Our work with the US Army and the National Guard in developing and testing this new Ricardo system to improve the stability and dynamic performance of the HMMWV, demonstrates our ability to engineer practical and robust solutions for military vehicles.

“The safety of our service men and women is of paramount importance, and we are proud that the Ricardo rollover mitigation system has shown sufficient promise, this project is now viewed by Congress as a priority in the next fiscal year.”
