Innovation Solution
A method and apparatus that modifies the electronic controls of EVs to mimic the sensory experience of driving a performance ICE car by using a customizable Heads-Up Display (HUD) to project racing lines, gauges, and simulate engine sounds, integrating sensor data to create a virtual cockpit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a Heads-Up Display (HUD) is implemented in an EV to provide visual feedback, then the driving experience is enhanced, but the device complexity increases
Solution Approach 1:
The HUD system serves multiple functions: it displays speed, navigation, performance metrics, and sensory feedback simultaneously. The electronic control unit integrates data from multiple sensors (accelerometers, gyroscopes, wheel speed sensors) and processes them through a single display interface, reducing the need for separate systems for each function.
Solution Approach 2:
The electronic control unit acts as an intermediary between the various sensors and the HUD display. It receives raw data from accelerometers, gyroscopes, and wheel speed sensors, processes this information, and translates it into visual representations on the HUD, simplifying the overall system architecture.
2Ease of operation
If sensor data is integrated to create a virtual cockpit experience, then the sensory feedback is improved, but the manufacturing complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: acceleration sensing (accelerometer), rotational sensing (gyroscope), wheel speed measurement (wheel speed sensors), data processing (electronic control unit), and visual output (HUD). Each module can be developed, tested, and manufactured independently, then integrated through standardized communication protocols.
Solution Approach 2:
The electronic control unit serves as a universal platform that handles data acquisition, processing, and display control for multiple sensor types. This multi-functional approach reduces the need for separate dedicated circuits for each sensor, simplifying manufacturing.
3Loss of information
If the HUD projects multiple parameters (speed, navigation, performance metrics), then the information availability is improved, but the illumination intensity requirements increase
Solution Approach 1:
The HUD displays only the most relevant information based on driving conditions and driver preferences. The electronic control unit prioritizes critical data (speed, navigation) over secondary data (performance metrics), reducing the total information load and corresponding illumination requirements while maintaining essential information availability.
