Evacuation Driving Assistance via Central Server Location Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle stopping apparatuses are unable to determine an appropriate evacuation location if it is outside the camera's imaging field or if there are no suitable locations within the detection area, limiting their effectiveness in assisting drivers in a normal-driving disabled state.
Innovation Solution
An evacuation driving assistance system that includes a driver determination unit to assess the driver's state, a notification unit to send location information to a central system, and an evacuation driving execution unit to receive and execute driving instructions towards a determined evacuation location, allowing for selection of an appropriate evacuation site even if it is outside the camera's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the evacuation location is determined based on the image captured by the camera mounted in the own vehicle, then the evacuation location can be determined within the imaging field, but it is impossible to determine an evacuation location outside the imaging field
Solution Approach 1:
The patent introduces a center (server) as an intermediary that receives location information from the own vehicle and determines the evacuation location based on map data and traffic information. This mediator extends the detection capability beyond the camera's imaging field by accessing external data sources, allowing the system to identify suitable evacuation locations anywhere along the route, not just within the limited camera view.
2Device complexity
If the evacuation location is determined using only the camera's imaging field, then the system structure remains simple, but the reliability of evacuation location determination decreases when no suitable location exists within the detection area
Solution Approach 1:
The patent transitions from a two-dimensional camera imaging field to a three-dimensional spatial search by utilizing map data and geographic information stored in the center. This dimensional expansion allows the system to search for evacuation locations along the entire route, not just within the limited camera view, significantly improving reliability while maintaining reasonable system complexity through cloud-based processing.
3Speed
If the camera continuously monitors for evacuation locations, then the detection coverage is limited to the imaging field, but the response time to identify suitable evacuation locations may be delayed
Solution Approach 1:
The center pre-stores map data, road information, and potential evacuation location data in advance. When the own vehicle needs evacuation location determination, the center can immediately query and process this pre-prepared information, providing rapid response without the need for continuous real-time camera scanning. This preliminary preparation of data enables fast evacuation location determination while expanding the effective detection area.

AI summary
An evacuation driving assistance apparatus capable of evacuation driving toward an appropriate evacuation location is provided. In the evacuation driving assistance apparatus, a driver determination unit determines whether or not a driver of an own vehicle is in a normal-driving enabled state. If it is determined by the driver determination unit that the driver of the own vehicle is in a normal-driving disabled state, a notification unit provides a notification of location information of the own vehicle to a center. The center is capable of determining an evacuation location based on the location information of the own vehicle, and transmitting the evacuation location. A reception unit receives the evacuation location transmitted by the center. An evacuation driving execution unit executes evacuation driving toward the evacuation location received by the reception unit.
