Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance and autonomous driving technologies fail to adequately evaluate damage to the self-vehicle and other objects when determining an emergency traveling route, as they do not consider the presence or absence of alternative routes or the moving velocity of other objects.
Innovation Solution
An information processor with processing circuitry and memory that acquires movement information and area data to calculate damage evaluation values for potential collisions, determining a target position that minimizes damage by considering the velocity and movement direction of both the self-vehicle and other objects, and controlling the vehicle to move to this position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the traveling route for emergency is determined without considering the presence or absence of alternative routes or the moving velocity of other objects, then the calculation process is simple and fast, but the damage evaluation to the self vehicle and other objects is insufficient
Solution Approach 1:
The patent segments the emergency route determination into distinct evaluation stages: first identifying alternative routes, then evaluating damage to the self vehicle, and separately evaluating damage to other objects. This segmentation allows comprehensive damage assessment while maintaining structured calculation processes.
Solution Approach 2:
The patent performs preliminary identification of alternative routes and preliminary damage evaluation calculations before finalizing the emergency route selection. By pre-calculating damage evaluation values for multiple routes and objects, the system prepares comprehensive data in advance, enabling more accurate damage assessment without excessive computational complexity during critical emergency response.
2Measurement precision
If the emergency route is determined without considering the moving velocity of other objects, then the response time is short, but the accuracy of collision damage prediction is reduced
Solution Approach 1:
The patent performs preliminary identification of alternative routes and preliminary damage evaluation calculations before finalizing the emergency route selection. By pre-calculating damage evaluation values for multiple routes and objects, the system prepares comprehensive data in advance, enabling more accurate damage assessment without excessive computational complexity during critical emergency response.
Solution Approach 2:
The patent uses simplified damage evaluation models that provide sufficiently accurate predictions for emergency decision-making without requiring complex, time-consuming calculations. The system accepts approximate damage evaluation values that are calculated quickly, rather than pursuing highly precise but time-prohibitive simulations, thereby balancing accuracy with rapid response requirements.

AI summary
According to one embodiment, an information processor includes a memory and processing circuitry. The circuitry receives area information indicating a second area in a first area around a movable body apparatus and third areas in the first area, wherein the movable body apparatus is movable in the second area and an object is present in each of the third areas. The circuitry receives movement information including at least one of a velocity, a movement direction or an acceleration of the apparatus. The circuitry acquires evaluation values each indicative of a damage to be caused when the apparatus collides with each object in the third areas, and determines, based on the evaluation values, a position corresponding to a first object which causes a least damage.
