Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face safety risks when traveling through intersections or crossroads due to unreliable input signals, particularly from image sensors, which fail to ensure safe navigation and collision avoidance.
Innovation Solution
A vehicle control system that calculates the reliability of various input signals, including behavior information of front vehicles, traffic light states, brake light information, and surrounding vehicle flow, using multiple calculating units and IoT sensors to generate control signals for safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of sensors and navigation devices are equipped for autonomous vehicle operation, then the vehicle's ability to recognize surrounding conditions and determine driving strategy is improved, but the reliability of input signals remains insufficient leading to safety accidents at intersections
Solution Approach 1:
The system continuously monitors and evaluates the reliability of input signals from multiple sensors in real-time, using feedback mechanisms to assess signal quality and make dynamic adjustments to autonomous driving operations based on the reliability assessment
Solution Approach 2:
The autonomous vehicle system dynamically adjusts its operational mode between fully autonomous and driver-authority based on real-time reliability assessments of input signals, allowing the system to adapt its degree of automation according to current signal conditions
2Device complexity
If the autonomous vehicle operates based on image sensor data alone, then the system complexity is reduced, but the reliability is insufficient to avoid safety accidents at intersections or crossroads
Solution Approach 1:
The system merges data from multiple sensor types including image sensors, additional sensors, and navigation devices to create a comprehensive input signal system that assesses reliability through combination rather than relying on a single sensor source
3Speed
If the autonomous vehicle travels through intersections without reliability calculation, then the operation speed is maintained, but safety accidents cannot be prevented due to unreliable input signals
Solution Approach 1:
The system performs preliminary reliability assessment of input signals before the autonomous vehicle enters intersections or crossroads, allowing advance preparation and mode switching to ensure safety without compromising overall operation speed
Data Source
AI summary
A vehicle control system uses reliability of an input signal of an autonomous vehicle to safely travel through an intersection or a crossroad. The system includes a first calculating unit that calculates reliability for behavior information of a front vehicle and a second calculating unit calculates reliability for state information of a traffic light in the crossroad or the intersection based on a surrounding vehicle. A third calculating unit calculates reliability for brake light information of the front vehicle and a fourth calculating unit calculates reliability for flow information of the surrounding vehicle passing the crossroad or the intersection. A determining unit generates a vehicle control signal according to the calculated reliability.
