Remote Parking Control Logic for Automatic Vehicle Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote parking systems either require users to manually stop the vehicle after parking, risking accidents like carbon monoxide poisoning, or keep the automatic stop mode enabled, leading to unintentional vehicle shutdown during normal driving, increasing user burden.
Innovation Solution
A control device and method that enables an automatic stop mode upon completion of movement control, allowing the mode to be disabled only when the vehicle is stopped, and requires a stop operation when enabled, reducing user burden by preventing unintended shutdowns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the automatic stop mode is kept enabled until the vehicle is stopped after waiting to receive a remote parking instruction, then safety is improved by preventing carbon monoxide poisoning, but the user burden increases because the vehicle may unintentionally stop during normal driving operations
Solution Approach 1:
The automatic stop mode dynamically changes its state based on the vehicle's operating conditions. The mode is enabled only when specific conditions are met (vehicle in P range, automatic parking function activated, engine running), and automatically disabled when the vehicle is stopped or when normal driving operations are detected. This dynamic adjustment resolves the contradiction by providing safety when needed while preventing unintended shutdowns during normal operation.
Solution Approach 2:
The system changes the operational parameter of the automatic stop mode (enabled/disabled state) based on detected vehicle conditions. When the vehicle transitions from a stopped state to a moving state, or when normal driving operations are detected, the parameter changes from enabled to disabled, preventing unintended shutdowns while maintaining safety during remote parking operations.
2Ease of operation
If the automatic stop mode is made freely switchable between enabled and disabled by user operation, then ease of operation is improved, but safety deteriorates because the user may forget to stop the vehicle after remote parking
Solution Approach 1:
The system provides self-service by automatically managing the stop operation after remote parking completion. When the remote parking function completes its operation, the system automatically executes the stop command without requiring user intervention. This eliminates the safety risk of users forgetting to stop the vehicle while maintaining the convenience of free switching capability.
Solution Approach 2:
The system implements feedback by monitoring the completion status of remote parking operations and automatically responding with appropriate stop commands. The system receives feedback about the parking operation status and automatically executes stop commands when appropriate, ensuring safety without burdening the user with manual operations.
3Reliability
If the movement controller receives no stop operation when the automatic stop mode is enabled, then safety is improved by preventing unintended shutdowns, but device complexity increases due to the need to monitor mode state and operation reception conditions
Solution Approach 1:
The system performs preliminary action by pre-establishing the automatic stop mode state before normal driving operations can occur. The mode is enabled only when the vehicle is in a specific state (P range, automatic parking activated), which prevents normal driving operations from triggering unintended shutdowns. This preliminary configuration simplifies the control logic by eliminating the need for complex real-time monitoring during normal operation.

AI summary
A control device includes: a circuit configured to receive an instruction from outside a moving body by a terminal of a user of the moving body; a movement controller configured to perform movement control of the moving body based on the instruction and stop the movement control based on a stop operation for the movement control; and a drive controller configured to set an automatic stop mode in which driving of the moving body is automatically stopped based on completion of the movement control. The drive controller enables the automatic stop mode when the moving body is in a state of waiting to receive the instruction, and keeps the automatic stop mode enabled until the driving of the moving body is stopped, and the movement controller receives the stop operation when the automatic stop mode is disabled and receives no stop operation when the automatic stop mode is enabled.
