Abstract

A computer system (140, 160, 310, 500) for reducing rotational speed of at least one wheel (110) of a vehicle (100), the computer system (140, 160, 310, 500) comprising processing circuitry (150, 170, 315, 502) configured to: determine a first value of rotational kinetic energy (E₁) of one or more powertrain components (110, 120, 210, 220, 230, 240, 250, 260, 320) of the vehicle (100), when the at least one wheel (110) is rotating at a current rotational speed (ω₁); acquire a second value of rotational kinetic energy (E₂) of the one or more powertrain components (110, 120, 210, 220, 230, 240, 250, 260, 320), when the at least one wheel (110) is rotating at a rotational speed (ω₂) where the wheel (110) has a desired amount of slip; determine an energy difference (ΔE) between the first value of rotational kinetic energy (E₁) and the second value of rotational kinetic energy (E₂); determine a first retardation torque pulse corresponding to the determined energy difference (ΔE); and cause the determined first retardation torque pulse to be applied to at least one of the one or more powertrain components to reduce the rotational speed of the at least one wheel (110).
