Gear Lever Controlled Vehicle Assistance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle driver assistance systems for tailbacks or slow traffic are expensive and potentially dangerous due to their reliance on sophisticated sensors and technology, making them unsuitable for lower-range vehicles and lacking intuitiveness in activation.
Innovation Solution
An automotive electronic control system that uses a servo-assisted powertrain and braking system, controlled by a body computer and electronic control units, allowing drivers to manually control acceleration and deceleration using the gear lever in specific directions, eliminating the need for expensive sensors and providing a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sophisticated radar, video and/or ultrasound sensors, adaptive cruise control systems with Stop-and-Go function, lane keeping support systems and electromechanical steering are used, then driver assistance functionality is improved, but manufacturing cost increases significantly
Solution Approach 1:
The patent extracts and removes the expensive sensor suite (radar, video, ultrasound sensors) and complex systems (lane keeping support, electromechanical steering) from the driver assistance system, retaining only the essential gear lever-based control mechanism that can be implemented with existing vehicle components
Solution Approach 2:
The patent replaces expensive, complex systems with simpler, cheaper alternatives that can be implemented using existing vehicle components, making the technology economically viable for lower-range vehicles
2Extent of automation
If the driver assistance system completely takes over control of the motor vehicle, then automation level is improved, but driver engagement decreases and safety may be compromised
Solution Approach 1:
The patent implements partial automation where the system assists the driver with acceleration and deceleration control through the gear lever, but the driver maintains full control and engagement, avoiding complete automation that would disengage the driver
Solution Approach 2:
The gear lever serves as an intermediary control mechanism that maintains driver engagement while providing automated assistance, acting as a mediator between full manual control and complete automation
3Ease of operation
If complex sensor-based systems are implemented, then driving assistance capability is improved, but system complexity and potential distraction to the driver increases
Solution Approach 1:
The patent makes the existing gear lever multi-functional by enabling it to control acceleration and deceleration in addition to its traditional gear shifting function, eliminating the need for separate complex control systems
Solution Approach 2:
The system utilizes existing vehicle components (gear lever, transmission control systems) to provide driver assistance functionality, allowing the vehicle's own components to serve the dual purpose of traditional operation and assisted driving
