Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicles and mobile robots face challenges in detecting their surroundings accurately and efficiently at high speeds, while also requiring complex and costly sensor suites and communication systems that are vulnerable to electronic jamming.
Innovation Solution
The proposed solution involves an autonomous vehicle equipped with a detection system comprising four NanoPOP detection devices mounted at the corners of the vehicle's roof, each featuring a videocamera and infrared visor. This system allows for 360-degree horizontal and vertical field of vision without the need for lidar, radar, or satellite navigation antennas, and uses a hierarchical electronic controller system and Quantum Key Distribution for secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex sensor suite including lidar, radar, and satellite navigation antennas is used, then measurement precision and detection accuracy are improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates unnecessary sensor components (lidar, radar, satellite navigation antennas) from the traditional autonomous vehicle sensor suite, retaining only the essential videocamera and infrared visor that can adequately perform detection functions when properly positioned and configured
Solution Approach 2:
The patent makes the detection system universal by using multi-functional videocameras and infrared visors that can perform multiple detection tasks (obstacle detection, navigation, environmental monitoring) simultaneously, replacing multiple specialized sensors with fewer versatile components
2Reliability
If traditional sensor suites are used, then detection coverage is improved, but vulnerability to electronic jamming and cyber attacks increases
Solution Approach 1:
The patent converts the vulnerability to electronic attacks into an advantage by deliberately choosing passive optical sensors (videocameras and infrared visors) that cannot be jammed or hacked through electronic means, transforming what could be seen as a limitation into a security feature
Solution Approach 2:
The patent employs inexpensive, mass-producible videocamera and infrared visor components that can be easily replaced if needed, rather than relying on expensive, complex sensor systems that are vulnerable to sophisticated electronic attacks
3Productivity
If high-speed autonomous operation is required, then productivity is improved, but detection precision and response time become more critical
Solution Approach 1:
The patent implements preliminary action by using infrared visors to detect thermal signatures of obstacles before they become visible in normal light conditions, providing advance warning and allowing the vehicle to prepare for potential hazards at high speeds
Solution Approach 2:
The patent adds another dimension to detection by combining visible light videocameras with infrared thermal detection, creating a multi-dimensional sensing capability that works effectively at various speeds and lighting conditions

AI summary
An electric vehicle with autonomous drive includes a detection system for detecting the environment surrounding the vehicle. The detection system includes a plurality of detection devices (2) mounted on the vehicle. The detection device (2) comprises a support (200), an articulated wrist (201) pivotally mounted on said support (200) around a first substantially vertical axis (202) and a detector body (205) pivotally mounted on said wrist (201) around a second substantially horizontal axis (209) orthogonal to said first axis (202) and carrying a videocamera (206) for daylight vision, and an IR visor (208) for night vision or for vision in conditions of low visibility. The detection devices (2) are at least three in number and include one or two front detection devices and one or two rear detection devices (2). The vehicle further comprises a front area electronic controller (S1), which controls the two front detection devices (2) or the single front detection device (2) for processing front vision data, a rear area electronic controller (S2) which controls two rear detection devices (2) or the single rear detection device (2) for processing rear vision data and a supervisor electronic controller (S5) which controls said front area and rear area controllers (S1, S2).
