Line-of-Sight Vehicle Guidance for Low-Cost Target Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for guiding autonomous vehicles require dedicated devices for recognizing target locations, leading to increased costs and complexity.
Innovation Solution
A pedestrian device and an in-vehicle device that utilize line-of-sight-based guidance, where the pedestrian device transmits position data of a sight focusing location to the in-vehicle device, allowing the vehicle to autonomously move to the designated target location using existing safe driving assistance wireless systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated devices are used for recognizing target location candidates, then the system can guide autonomous vehicles to proper locations, but the cost of introducing the system increases
Solution Approach 1:
The patent applies universality by enabling existing pedestrian terminals and in-vehicle terminals to perform multiple functions: their original safe driving assistance functions plus the new function of target location recognition and guidance. The existing terminals are utilized to transmit and process line-of-sight information, eliminating the need for dedicated recognition devices and reducing system complexity and cost while maintaining guidance reliability
Solution Approach 2:
The patent implements self-service by having the existing pedestrian terminal and in-vehicle terminal serve themselves for the additional function of target location recognition. These terminals already possess communication and position data capabilities, which are leveraged to transmit and process line-of-sight information without requiring external dedicated devices, thereby reducing overall system complexity
2Device complexity
If existing safe driving assistance wireless systems are utilized for line-of-sight-based guidance, then the system cost is reduced, but the device must perform multiple functions
Solution Approach 1:
The patent directly applies multi-functionality by configuring existing pedestrian terminals and in-vehicle terminals to perform both their original safe driving assistance communications and the new target location recognition and guidance functions. The terminals transmit position data, process line-of-sight information, and enable autonomous vehicle guidance, demonstrating versatile functionality within existing hardware

AI summary
A system for guiding an autonomous vehicle to a target location includes a pedestrian terminal carried by a user of the vehicle; an in-vehicle terminal mounted in the vehicle; and a wearable terminal worn on the user's body to detect a sight focusing status of the user. The pedestrian terminal is configured to transmit and receive information to and from the in-vehicle terminal, determine if there is a risk of collision between the vehicle and the user, and provide an alert to the pedestrian. The in-vehicle terminal is configured to transmit and receive information to and from the pedestrian terminal, determine if there is a risk of collision between the vehicle and the user based on the information received from the pedestrian terminal, and cause an autonomous driving ECU to perform cruise control so as to avoid the collision.
