Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack efficient automated actuation mechanisms that can track external objects and validate their trajectory to prevent conflicts with vehicle systems, particularly in determining acceptable ranges and positions for safe operation.
Innovation Solution
An apparatus and method utilizing an external object tracking system, such as radar or passive RF entry systems, to track and validate objects, determining their trajectory and authenticating electronic security tokens to command vehicle actuators like door locks or openers based on non-conflicting trajectory information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated actuation is implemented without trajectory validation, then ease of operation is improved, but safety and reliability deteriorate due to potential conflicts with external objects
Solution Approach 1:
The system performs preliminary trajectory prediction and validation before executing the actuation command. The controller calculates the projected trajectory of the actuated vehicle system and validates it against predicted object trajectories in advance, ensuring safety before the actuation occurs.
Solution Approach 2:
The system continuously monitors external objects using tracking systems, feeds trajectory information back to the controller, and adjusts actuation commands based on this feedback. This closed-loop control ensures that automated actuation remains safe by adapting to real-time object positions and movements.
2Reliability
If external object tracking and validation systems are added, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The controller performs multiple functions including object trajectory prediction, conflict detection, security token authentication, and actuation command generation within a single integrated system. This multi-functionality reduces the need for separate dedicated systems for each function, thereby managing complexity while maintaining safety.
Solution Approach 2:
The patent introduces a trajectory validation module as an intermediary between the actuation command generator and the vehicle system actuator. This intermediary layer processes trajectory information and validates commands without requiring complete system redesign, thereby managing complexity through modular addition.
3Object-affected harmful factors
If trajectory prediction and validation are performed, then harmful factors are reduced by preventing conflicts, but use of energy increases due to continuous tracking and computation
Solution Approach 1:
The system performs trajectory validation at periodic intervals and at critical decision points rather than continuously. The controller validates trajectories at predetermined acceptable ranges and before actuation commands are executed, reducing computational load and energy consumption while maintaining safety.
Solution Approach 2:
The system focuses trajectory validation computations on critical zones and high-risk scenarios rather than uniformly analyzing all possible trajectories. By concentrating computational resources on partial but critical validation cases, the system reduces overall energy consumption while preventing harmful conflicts.
