Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing vehicle control systems, a terminal device with insufficient battery power may fail to issue parking instructions or acquire information from the vehicle, leading to communication failures during automated parking operations.
Innovation Solution
A vehicle control system that includes a recognizer for environmental awareness, a driving controller for speed and steering control, an acquirer for monitoring the terminal device's energy level, and a notifier that prompts energy increase when the level falls below a threshold, ensuring communication and instruction execution for parking and exit operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the terminal device operates with low remaining energy, then the device can continue to function, but communication reliability for parking instructions fails
Solution Approach 1:
The system performs preliminary detection of the terminal device's remaining energy amount before executing parking instructions. When the energy level is below the first threshold, the system proactively notifies the occupant to charge the device, preventing communication failures before they occur. This advance action ensures reliable communication while maintaining device operation.
Solution Approach 2:
The system continuously monitors the remaining energy amount of the terminal device and provides feedback to the occupant through notifications. This feedback mechanism allows the system to adjust its operation based on energy levels, maintaining communication reliability by alerting users to charge before energy depletion occurs.
2Reliability
If the system continuously monitors terminal device energy level, then communication reliability is maintained, but system complexity increases
Solution Approach 1:
Instead of continuously monitoring energy levels at all times, the system performs energy detection at specific critical moments: before issuing parking instructions and before allowing vehicle exit. This partial monitoring approach maintains communication reliability for essential operations while avoiding the complexity of continuous real-time monitoring.
Solution Approach 2:
The system uses threshold-based parameter changes to simplify monitoring. By comparing the remaining energy amount against predefined thresholds (first threshold for parking instructions, second threshold for vehicle exit), the system maintains reliability without requiring complex continuous analysis of energy levels.
3Reliability
If the system prevents exit when energy is low, then communication reliability is ensured, but loss of time occurs due to delayed exit
Solution Approach 1:
The system performs preliminary detection of energy levels before the exit operation is initiated. When the remaining energy is below the second threshold, the system notifies the occupant in advance that exit will be prevented. This allows the occupant to charge the device beforehand, ensuring reliable communication during exit while minimizing time loss by avoiding last-minute interruptions.
Solution Approach 2:
The system provides a buffer by notifying occupants before preventing exit. The dual-threshold system creates a cushioned approach: the second threshold prevents exit to ensure reliability, but the advance notification gives occupants time to charge, cushioning against the time loss that would otherwise occur from abrupt exit prevention.

AI summary
A vehicle control system of an embodiment includes a recognizer that recognizes a peripheral environment of a vehicle, a driving controller that performs driving control based on speed control and steering control of the vehicle on the basis of a recognition result of the recognizer, an acquirer that acquires a remaining energy amount of a terminal device, and a notifier that performs a notification for prompting an increase of the remaining energy amount when the remaining energy amount acquired by the acquirer while an occupant is aboard the vehicle is less than a first threshold in a case where an instruction to cause a vehicle to enter a parking area in which the vehicle is able to be parked by traveling based on the driving control or an instruction to cause the vehicle to exit the parking area is performed by the terminal device.
