Abstract An off-road ramp travelling vehicle assistance system for a utility vehicle comprising an entry landmark marking a defined down-hill entry section of a ramp as a first ramp section. The entry landmark is located in advance of the start of the ramp and configured to be detectable by the utility vehicle. The utility vehicle comprises a slope meter for measuring a slope value and a location meter for measuring a location value of the utility vehicle. A vehicle's computer unit is configured to perform detection of the landmark when approaching the landmark and start of a ramp travelling vehicle assistance function in response to the detection. In course of the ramp travelling vehicle assistance function there is a repeated determination of a vehicle's slope state based on multiple slope values and location state with respect to a ramp section based on at least one location value and a control of the vehicle's speed with regard to a defined speed limit. The ramp travelling vehicle assistance function provides different speed control modes which are automatically selectable depending on the determined slope state and location state.
