Integrated Driving Control Device for Cabin Space Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control mechanisms, such as steering wheels, accelerator pedals, and shift levers, occupy significant cabin space, leading to reduced interior space utilization, increased vehicle weight, and manufacturing costs, especially with the advent of autonomous driving systems that minimize driver interaction.
Innovation Solution
An integrated driving control device that combines steering, acceleration, deceleration, and shifting functions into a single unit, utilizing a knob unit with a rotating and sliding mechanism, accompanied by sensors and springs for feedback, and Hall effect sensors for precise control, allowing for reduced physical controls within the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional driving-related devices (steering wheel, accelerator pedal, brake pedal, shift lever) are provided in the vehicle interior, then driving control functions are achieved, but cabin space is significantly occupied
Solution Approach 1:
The patent merges steering wheel, accelerator pedal, brake pedal, and shift lever functions into a single integrated control device. The control unit integrates multiple driving control functions that were previously distributed across separate devices, thereby reducing the total space occupied in the vehicle interior while maintaining all necessary driving control capabilities
Solution Approach 2:
The integrated control device is designed to perform multiple functions simultaneously - steering control, acceleration control, braking control, and shift control - all through one device. This multi-functional approach allows the system to replace several separate devices with a single universal control unit, maximizing cabin space utilization
2Ease of operation
If multiple separate driving control devices are installed in the vehicle, then comprehensive driving control is achieved, but vehicle weight increases
Solution Approach 1:
By combining multiple driving control devices into one integrated control unit, the total weight of the control system is reduced. Instead of having separate weights for steering wheel, accelerator pedal, brake pedal, and shift lever, the integrated design consolidates these functions into a single lighter structure
3Ease of operation
If conventional separate driving devices are used, then driving control functions are provided, but manufacturing costs increase
Solution Approach 1:
The integration of multiple driving control functions into a single control unit reduces the number of components that need to be manufactured, assembled, and quality-tested. This consolidation simplifies the manufacturing process and reduces overall production costs compared to producing and assembling multiple separate devices
Solution Approach 2:
The integrated control device serves as a universal platform that can be standardized across different vehicle models, reducing tooling costs and enabling economies of scale in manufacturing
