Autonomous Parking Update Timing for Remote Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assistance systems for vehicles lack optimal timing for program updates, which can impair convenience, especially when updates are performed during parking assistance operations, and there is a need to ensure user safety and flexibility in parking scenarios.
Innovation Solution
A control device for vehicles that performs autonomous parking with a processor configured to execute first and second parking assistance controls, updating programs after power is turned off, with stricter start conditions for remote parking mode to ensure user safety and flexibility, and determining update necessity based on stopping position or travel record.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If program update is performed after parking assistance control, then system reliability is improved, but convenience deteriorates when update timing is not properly controlled
Solution Approach 1:
The patent implements dynamic adjustment of update start conditions based on the type of parking assistance control executed. For remote parking control (first control), the system sets a first start condition that includes a predetermined time period elapsing after power-off, whereas for automated parking control (second control), it sets a second start condition with shorter or no time requirement. This dynamic condition adjustment resolves the contradiction by adapting update timing to the specific parking scenario, ensuring reliability while maintaining user convenience.
2Productivity
If program update is performed immediately after power-off, then productivity is improved, but safety deteriorates when user needs to return to vehicle
Solution Approach 1:
The patent applies preliminary action by setting a predetermined time period to elapse after power-off before allowing program update to start, specifically for remote parking control scenarios. This time buffer ensures that if the user needs to return to the vehicle, they have sufficient time to do so safely before the update begins and the vehicle becomes immobile. This resolves the contradiction by prioritizing safety through advance timing consideration while still enabling efficient updates.

AI summary
A control device for a vehicle includes: a processor for performing control for autonomously parking the vehicle to a target position; and a storage unit storing a program necessary for travel control of the vehicle. As the control, the processor performs first control for starting movement of the vehicle to the target position in a state where a user of the vehicle is not in the vehicle, and second control for starting movement of the vehicle to the target position in a state where the user is in the vehicle, the processor updates the program, after a power of the vehicle is turned off and the processor executes the first control or the second control, and a start condition for updating the program is set more strictly when the first control is executed than when the second control is executed.
