Vehicle Driving Mode Control for Zone Restriction Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems fail to ensure appropriate driving in designated zones, as they rely on human intervention and do not automatically adjust driving modes based on zone types, leading to potential unauthorized vehicle presence in restricted areas.
Innovation Solution
A vehicle system that determines its location within free driving and alternative driving zones using position information and automatically switches between free driving and alternative driving modes, including partially and fully automated operations, to ensure compliance with zone restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle control system restricts motion capability when the vehicle enters the restricted area, then the vehicle is prompted to leave the restricted area, but the vehicle cannot be automatically driven out if the user does not intend to move
Solution Approach 1:
The vehicle control system automatically detects zone restrictions and executes driving maneuvers to leave restricted areas without requiring user intervention. The system serves itself by autonomously interpreting zone rules and controlling vehicle operations to ensure compliance.
Solution Approach 2:
The system continuously monitors vehicle position relative to restricted areas and adjusts driving behavior based on this feedback. When the vehicle enters a restricted zone, the system receives feedback about the violation and automatically implements corrective driving actions to exit the zone.
2Adaptability or versatility
If the vehicle relies on human driver judgment to determine appropriate driving modes in different zones, then the driver has flexibility in decision-making, but the vehicle may not comply with zone restrictions if the driver does not intend to leave
Solution Approach 1:
Instead of relying on the driver to decide when to leave restricted areas, the system inverts the decision-making process by automatically determining and executing the necessary driving actions to comply with zone restrictions, removing reliance on human judgment in this context.
Solution Approach 2:
The control system acts as an intermediary between the driver and the zone restriction requirements, automatically interpreting and enforcing zone rules without requiring the driver to make judgment calls about compliance.
3Reliability
If the vehicle control system permanently disables forward motion capability after extended stay in restricted area, then unauthorized presence is prevented, but the vehicle loses mobility functionality
Solution Approach 1:
The system automatically executes driving maneuvers to leave restricted areas before permanent disabling is triggered, preventing the loss of mobility functionality. By taking preliminary automatic action to comply with restrictions, the system avoids the need for permanent disabling.
Solution Approach 2:
The vehicle control system autonomously manages compliance with zone restrictions through automatic driving operations, eliminating the need for permanent disabling measures and preserving vehicle mobility while ensuring restriction compliance.

AI summary
A vehicle includes an on-board controller. A position of the vehicle is detected by a positioning sensor and a CPU of the on-board controller Based on the position of the vehicle and area information stored in a memory, the CPU determines whether the vehicle is in a free driving zone, an alternative driving zone, or a remote driving zone. The CPU sets a driving mode to either one of a free driving mode, an alternative driving mode, and a remote driving mode based on a signal of the driving mode of the vehicle inputted by a main key of a vehicle main body and information indicating which driving zone the vehicle is in. A CPU of the vehicle main body controls an operation of the vehicle in accordance with the set driving mode. The on-board controller may be provided by a mobile terminal.
