【Abstract】To address the concerns about the range anxiety and low energy recovery eficiency of electric vehicles and hydrogen fuel cell-powered commercial vehicles，this paper，basedon thedownhillsliding characteristics of the vehicleandthecurrentoperating status ofthehydrogen fuelcellstack，proposesanenergy recoverycontrol method based on Predictive Cruise Control （PCC）.This method relies on inteligent connected products to obtain information such as the slopeand length of theroadahead，andtransmits itthrough theAdvanced DriverAssistanceSystems Interface Specifications （ADASIS） v2 protocol to the Vehicle Control Unit （VCU）. The VCU then adjusts the speed entering and exitingtheslopebasedonthevehicle'soperating statusandsimultaneouslyoptimizesthepowerofthehydrogen fuel cell stack，making fulluseof inertia to climb the slope and reduce energy consumption.The multi-steep slope section test in Mohe verified thatthis method can significantly improve energy recovery eficiencyandreduce the vehicle's energy consumption，providing technical support forthe improvement of the rangeof electricand hydrogen fuel cell-powered commercial vehicles.
