Claim:
1. A driver assisting system for a vehicle, said system comprising: a processing means; and a display means, said display means being adapted to display information on a screen of a vehicle hosting said system, said screen further being adapted to show the environment in front of the vehicle or a representation of the environment in front of the vehicle, wherein said vehicle extends in a longitudinal direction and a lateral direction, and wherein said longitudinal direction corresponds to the intended direction of travel of said vehicle, wherein said processing means is adapted to receive a first input data signal indicative of a velocity of said vehicle hosting said system, and a second input data signal indicative of an actual performed, on-going or impending lateral position change of said vehicle hosting said system, the processing means further being adapted to process at least the first and the second input data signals to thereby calculate an estimated vehicle path of said vehicle hosting said system, said display means being adapted to display said estimated vehicle path on said screen, and wherein said processing means is adapted to receive a third input data signal indicative of a friction value between said vehicle hosting said system and the ground on which said vehicle is traveling and a friction value of the ground in front of said vehicle, wherein the friction values indicated by the third input data signal are determined based on a combination of an estimated direct friction value and an estimated indirect friction value, the estimated indirect friction value based on a road surface classification, and wherein the processing means is adapted to process also said third input data signal to thereby calculate said estimated vehicle path based on the velocity, lateral position change, and friction values indicated by the first, second and third input signals.
