1. Method for driving a mining and/or construction machine, where said machine is arranged to be controlled by an operator by means of maneuvering means, where said operator, when driving said machine, provides steering commands by means of said maneuvering means for maneuvering said machine, wherein the method comprises, when said machine is being driven in an environment having at least a first obstacle, the steps of:

  • when said machine is within a first distance from said first obstacle, estimating a first path that has been requested by said operator by means of said steering commands,by means of a control system determining whether said machine when moving according to said requested first path will be driven within a second distance from said first obstacle, andwhen it is determined that said machine, when traveling according to said first path, will be driven within said second distance from said first obstacle, retard said machine by means of said control system;

    wherein, when determining said first distance to said first obstacle in said requested first path, said path is defined as an area in the direction of travel having a first length and a width corresponding at least to the width of the machine, where obstacles within said area have the result that the machine will be driven within said second distance from said first obstacle when traveling according to said requested path;

    wherein the width of said area is defined as a width corresponding to the width of the machine and a first lateral safety distance; and

    wherein said first lateral safety distance is a lateral safety distance being different from zero.
