Driver assisting system and method with windscreen heads-up display of vehicle environment
First 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, andwherein 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.

Abstract
A driver assisting system and method for a vehicle are provided. The system includes a processor and a display system. The display system is adapted to display information on a screen of a vehicle. The screen is adapted to show the environment in front of the vehicle or a representation thereof. The vehicle extends in a longitudinal direction and a lateral direction, the longitudinal direction corresponding to the intended direction of vehicle travel. The processor is adapted to receive a first input data signal indicative of a velocity of the vehicle, and a second input data signal indicative of an actual performed and/or on-going and/or impending lateral position change of the vehicle. The processor is further adapted to process at least the first and the second input data signals to calculate an estimated vehicle path, and the display system is adapted to display the estimated vehicle path on the screen.

13. A method of assisting a driver of a vehicle using a processing means and a display means wherein said display means is adapted to display information on a screen of a vehicle hosting said system, said screen further being adapted to present 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, the method comprising:
-
receiving in said processing means a first input data signal indicative of a velocity of said vehicle hosting said system; receiving in said processing means a second input data signal indicative of an actual performed, on-going or impending lateral position change of said vehicle hosting said system; receiving in said processing means 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; processing at least the first and the second and the third input data signals, using the processing means, to thereby calculate an estimated vehicle path of said vehicle hosting said system; and displaying said estimated vehicle path on said screen using said display means. - View Dependent Claims (14)
