Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of drive requests from multiple driving assistance systems in vehicles complicates arbitration processing, as described in existing technologies, making it difficult to efficiently manage movement control.
Innovation Solution
An information processing apparatus that includes a receiver, an arbitration unit, and output units to receive and arbitrate requests for vehicle movement control from multiple driving assistance applications, converting acceleration requests into power and outputting instruction information to actuators, thereby simplifying arbitration processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If arbitration processing is performed by converting target values to the same physical quantity as described in prior art, then arbitration can be performed, but the processing becomes complicated when multiple driving assistance systems are involved
Solution Approach 1:
The patent segments arbitration processing into two independent parts: longitudinal direction arbitration (acceleration/deceleration) and lateral direction arbitration (steering angle/yaw rate/rotation radius). Each direction is handled separately with its own arbitration logic, avoiding the need to convert all parameters to a single physical quantity. This segmentation simplifies processing while maintaining comprehensive arbitration capability across multiple driving assistance systems.
Solution Approach 2:
The patent creates a universal arbitration framework that can handle multiple types of driving assistance systems (autonomous driving, automatic parking, adaptive cruise control, lane keeping assistance) through a common interface. The arbitration unit accepts various input parameters (acceleration, steering angle, yaw rate, rotation radius) and processes them uniformly without requiring conversion to a single physical quantity, enabling multi-functional arbitration across diverse applications.
2Adaptability or versatility
If multiple types of driving assistance systems are increased, then more driving assistance functions are available, but arbitration processing becomes more complicated
Solution Approach 1:
The patent designs a universal arbitration unit that can accommodate multiple driving assistance systems (autonomous driving, automatic parking, adaptive cruise control, lane keeping assistance) through a standardized interface. The unit accepts various parameter types (acceleration, steering angle, yaw rate, rotation radius) without requiring conversion to a single physical quantity, enabling the system to handle increased system variety without proportionally increasing arbitration complexity.
Solution Approach 2:
The patent segments the arbitration process into independent longitudinal and lateral direction handling, allowing each direction to be processed separately. This segmentation enables the system to scale to multiple driving assistance systems by adding new applications to existing directional arbitration logic rather than redesigning the entire arbitration framework, thus maintaining simplicity while increasing adaptability.

AI summary
An information processing apparatus includes a receiver configured to receive a data set including a requested acceleration as information representing movement of a vehicle in a front-rear direction and any one of a steering angle, a yaw rate, and a rotation radius as information representing movement of the vehicle in a lateral direction from each of a plurality of applications, an arbitration unit configured to perform arbitration of information representing the movement of the vehicle in the front-rear direction and arbitration of information representing the movement of the vehicle in the lateral direction based on a plurality of the data sets received by the receiver, and a first output unit configured to output instruction information for driving an actuator based on an arbitration result of the arbitration unit.
