Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic driving technologies require vehicles to be equipped with costly sensors for environmental sensing, which increases production and maintenance costs and hinders the upgrade of non-automatic driving vehicles to vehicles with strong automatic driving capabilities.
Innovation Solution
A vehicle infrastructure cooperative system where external sensors independent of the vehicle collect and process environmental data, providing a vehicle exterior sensing result to a vehicle-side control device to assist in driving behavior control, reducing the need for on-board sensing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicles are equipped with on-board sensors for environmental sensing, then automatic driving capability is achieved, but production and maintenance costs increase
Solution Approach 1:
The patent introduces roadside infrastructure (servers, roadside units) as intermediaries between the environment and the vehicle. These intermediaries perform environmental sensing and information processing, then provide processed information to the vehicle. This mediator approach allows the vehicle to achieve automatic driving capability without carrying expensive on-board sensors, thus resolving the contradiction between capability and cost.
Solution Approach 2:
The patent extracts the environmental sensing function from the vehicle and relocates it to the roadside infrastructure. By taking out the sensing components from the vehicle system and placing them in the external environment, the vehicle no longer needs to carry expensive sensors while still obtaining the necessary environmental information for automatic driving.
2Measurement precision
If vehicles are equipped with on-board sensors for environmental sensing, then sensing performance is achieved, but maintenance costs increase
Solution Approach 1:
The roadside infrastructure serves as a mediator that performs environmental sensing and provides processed information to the vehicle. Since the sensing equipment is located in the roadside infrastructure rather than on the vehicle, maintenance operations can be performed on stationary equipment with easier access and lower costs, while the vehicle still receives high-quality sensing data.
3Adaptability or versatility
If non-automatic driving vehicles are upgraded to vehicles with strong automatic driving capabilities, then driving capability is improved, but the upgrade process is hindered by cost
Solution Approach 1:
The patent extracts the complex sensing and processing functions from the vehicle and places them in the roadside infrastructure. This allows non-automatic driving vehicles to be upgraded to automatic driving vehicles by simply adding communication capabilities to receive environmental information from the roadside, rather than installing complex sensor systems. This significantly reduces upgrade complexity and cost.
Solution Approach 2:
The roadside infrastructure serves multiple vehicles simultaneously, providing environmental sensing information to any vehicle that needs it. This universal service approach allows different vehicles to upgrade their automatic driving capabilities without each vehicle needing its own dedicated sensing system, reducing overall system complexity and cost.
