Solution Overview
Problem
Current driver assistance systems fail to effectively provide critical information about vehicle behavior and road conditions, leading to accidents due to inadequate awareness among drivers, and existing solutions require widespread vehicle adoption or overload drivers with excessive information.
Innovation Solution
A driver-assisting system that uses a processing unit and display means, such as a head-up display on the windscreen or a screen between the driver and windscreen, to project information about the vehicle's estimated path, stop distance, and minimum turning radius, utilizing sensors and cameras to process data on vehicle velocity, steering angle, and friction value, and alert drivers through color coding and haptic signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single warning signal is displayed in the instrument panel, then the system structure is simple, but the driver cannot fully understand the critical situation and fails to be warned of upcoming critical situations
Solution Approach 1:
The patent transitions from a single-dimensional warning signal to a multi-dimensional visualization system that displays estimated vehicle path, actual path, stop distance, and minimum turning radius simultaneously on the windscreen, allowing drivers to comprehend multiple critical parameters in one view
Solution Approach 2:
The system segments critical driving information into distinct visual components: estimated path indication, actual path indication, stop distance indication, and minimum turning radius indication, each displayed separately but coherently on the windscreen for comprehensive driver awareness
2Loss of information
If vehicle-to-vehicle information systems are deployed, then road condition information can be shared, but a large number of vehicles must be equipped for the system to function as intended
Solution Approach 1:
The system processes and utilizes only the vehicle's own data (velocity, steering angle, friction value) to calculate and display critical driving parameters, eliminating the need for complex vehicle-to-vehicle communication infrastructure and making the system functional with a single vehicle equipped
Solution Approach 2:
The patent extracts and processes only the essential data elements needed for path prediction (velocity, steering angle, friction value) from the vehicle's sensor suite, removing the dependency on external vehicle communication systems while maintaining core functionality

AI summary
A driver assisting system 6 for a vehicle 5 is provided. The system 6 comprises a processing means 7 and a display means 9, the display means 9 being adapted to display information on a screen 10 of a vehicle 5 hosting the system 6. The screen 10 further being adapted to show the environment in front of the vehicle 5, and/or a representation of the environment in front of the vehicle 5. The vehicle 5 extends in a longitudinal direction 1 and a lateral direction 3, and wherein the longitudinal direction 1 corresponds to the intended direction of travel of the vehicle 5. The processing means 7 is adapted to receive a first input data signal 11 indicative of a velocity of the vehicle 5 hosting the system 6, and a second input data signal 12 indicative of an actual performed and/or on-going and/or impending lateral position change of the vehicle 5 hosting the system 6. The processing means 7 further being adapted to process at least the first and the second input data signals 11, 12 to thereby calculate an estimated vehicle path 17 of the vehicle 5 hosting the system 6, and the display means 10 being adapted to display the estimated vehicle path 17 on the screen 9. The present invention also relates to a method of assisting a driver of a vehicle.
