Advanced driver assistance systems bring together a variety of component technologies, including speed and directional sensors, radars, cameras, electronic control units (ECUs), and control valves across the braking system. This means that maintenance and installation require both a broader knowledge base and a deeper understanding of how they interact with other components as well as the vehicle itself.
“Retrofitting these systems can be a very different, more complex job than replacing brake friction or servicing air dryers,” said Lance Hansen, Bendix North America regional vice president, fleet/trailer sales and service engineering. “Because in addition to the mechanical aspects of the install, it involves electronics know-how and the possible use of diagnostic software like Bendix ACom.”
Although many technicians are highly capable, with solid technical and mechanical skills, thorough training is a significant consideration when properly preparing them for the unique technical challenges associated with these systems. “Technicians who handle safety system vehicle upgrades should be immersed in brake system theory, including the function of both pneumatic and electronic components,” Hansen said.
Examples of training for the component technologies could include proper mounting locations, alignment, calibration of sensors, harness routing, and J1939 communication.
All these elements will better equip tomorrow’s retrofitting technicians. Classroom or online training alone typically won’t be enough to prepare them to do the job right.
“Retrofitting in-service vehicles with leading-edge, fully warrantied driver assistance systems will mark a major step forward in terms of driver, vehicle, and highway safety,” Hansen said. “Getting to that point, however, requires recognition of the unique nature of retrofits and the need for experienced suppliers, installers and OEMs to support these efforts. To ensure that retrofitted vehicles operate correctly every time, engaging qualified, knowledgeable support will be essential.”
