Remote Steering Tactile Interface for Vehicle Situational Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic driving systems, remote steering support is challenging due to the operator's inability to accurately grasp the vehicle's situation and its surroundings, leading to difficulties in transitioning to appropriate remote control, which can result in safety issues and inefficiencies.
Innovation Solution
An information processing system and device that acquire and generate tactile information for remote steering, allowing operators to effectively manage vehicle control through an interface, including data from the vehicle and its environment, to facilitate accurate and timely remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote steering is implemented with external operators, then vehicle control capability is improved, but operator's situational awareness deteriorates
Solution Approach 1:
The patent introduces an information processing system as an intermediary between the vehicle and the remote operator. This system acquires comprehensive vehicle data (position, speed, acceleration, sensor information) and peripheral environment data (maps, weather, traffic conditions), then presents this processed information to the operator through a display device. The intermediary transforms raw data into meaningful situational awareness for the remote operator, resolving the contradiction between enabling remote control and maintaining operator awareness.
Solution Approach 2:
The patent replaces the mechanical presence of an operator in the vehicle with an electronic information transmission system. Instead of the operator physically being in the vehicle to grasp the situation, the system substitutes this with electronic acquisition and presentation of vehicle and environment information. This substitution enables remote operation while compensating for the loss of direct situational awareness through comprehensive data presentation.
2Loss of information
If comprehensive information is presented to the operator, then situational awareness is improved, but information processing complexity increases
Solution Approach 1:
The patent segments the information processing function into distinct modules: an information acquisition unit that collects vehicle data and peripheral environment data separately, and an information generation unit that processes and integrates this data. This segmentation allows the complex processing task to be divided into manageable parts, reducing overall system complexity while still providing comprehensive situational information to the operator.
Solution Approach 2:
The information processing system is designed with multi-functional units that can handle various types of data (vehicle status, sensor information, map data, weather conditions) through standardized processes. The information acquisition unit and information generation unit serve multiple functions in processing different data types, reducing the need for separate specialized systems and thereby lowering overall complexity.
