Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-performance sports cars are underutilized on public roads due to speed limits and inexperienced drivers struggle with track driving, while existing driver assistance systems provide inadequate guidance for optimizing performance and safety.
Innovation Solution
A performance-enhancing driver assistance system that includes a localization device, ADAS, control system, and augmented reality interface mounted on a helmet, which processes environmental and dynamic data to suggest optimal driving commands and trajectories, adapting information display to the driver's perspective for improved performance and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic driver assistance devices continuously intervene to optimize vehicle performance, then driving safety and performance optimization are improved, but driving pleasure and driver engagement deteriorate
Solution Approach 1:
The system provides selective intervention rather than continuous automated control. It offers performance optimization suggestions and informative messages only when beneficial, allowing the driver to maintain engagement and pleasure while still receiving safety-critical assistance when needed.
Solution Approach 2:
The system continuously monitors vehicle dynamics, driver behavior, and environmental conditions to provide real-time feedback through informative messages. This feedback loop enables the driver to make informed decisions without removing control, balancing safety with driving enjoyment.
2Device complexity
If informative messages are projected onto fixed screens, then information delivery is simplified, but visibility and accessibility for drivers of different heights and positions deteriorate
Solution Approach 1:
The system dynamically adjusts the position, orientation, and content of information display based on detected driver position, height, and viewing angle. This ensures optimal visibility for all drivers regardless of their physical characteristics while maintaining a relatively simple display hardware configuration.
Solution Approach 2:
The information is selectively presented in different locations and formats based on the specific driver's position and needs. The system adapts the local display characteristics (position, angle, content) to match each driver's optimal viewing zone rather than using a fixed universal display position.
3Device complexity
If driver assistance systems provide generic information based on current vehicle state, then implementation is simple, but optimization of future mission performance deteriorates
Solution Approach 1:
The system analyzes the remaining mission profile and provides advance guidance about upcoming optimal actions (braking points, gear shifts, trajectory adjustments). This preliminary information allows the driver to prepare and execute optimized driving sequences rather than reacting to current state only.
Solution Approach 2:
The system acts as an intermediary between the vehicle's capabilities and the driver's intentions by providing synthesized guidance that combines current vehicle state with future mission requirements. This intermediary function bridges the gap between simple current-state monitoring and complex future-optimized control.

AI summary
A method for the performance-enhancing driver assistance of a road vehicle driven by a driver comprises the steps of: determining the current position and orientation of the road vehicle, detecting a plurality of environmental data concerning the surrounding environment, detecting a plurality of dynamic data of the vehicle, determining the current position and orientation of a helmet within the road vehicle and suggesting to the driver, by means of an augmented reality interface device, one or more corrective actions to be carried out in order to accomplish a mission optimizing a cost function.
