DRIVE
June 7, 2023
The invention relates to a method for controlling a vehicle (1) comprising an electric powertrain, an energy storage system (ESS), regenerative braking functionality and cruise control functionality, wherein the cruise control functionality is configured to maintain a set cruise control speed of the vehicle during downhill travel by applying the regenerative braking functionality, the method comprising: obtaining (S11) a tolerance limit for an allowed increase in energy consumption caused by non-use of regenerative braking during downhill travel; obtaining (S12) information relating to an upcoming downhill road segment (DRS); based on the information relating to the upcoming downhill road segment (DRS), setting (S13) an allowed overspeed, caused by non-use or reduced use of the regenerative braking functionality, wherein the allowed overspeed exceeds the set cruise control speed for the upcoming downhill road segment (DRS) and is set based on the tolerance limit; and in the upcoming downhill road segment (DRS), controlling regenerative braking and rolling of the vehicle based on the set allowed overspeed, thereby reducing or preventing regenerative braking during the downhill travel. The invention also relates to a control unit, a vehicle, a computer program and to a computer readable medium.
