Parking Assist Apparatus Automatic Termination Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking assist systems require drivers to perform manual operations, such as shifting, even when terminating parking assist control, leading to inconvenience when the driver wants to move the vehicle to another location.
Innovation Solution
A parking assist apparatus that monitors and responds to driver operations, automatically terminating the parking assist control if the driver fails to perform a requested operation within a predetermined time, reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the parking assist apparatus executes braking force automatic control to stop the vehicle at a travel-direction switching position and waits for driver response, then the driver can perform the shift lever switching operation, but the driver feels inconvenient when wanting to terminate the parking assist control and move the vehicle to another place without performing the switching operation
Solution Approach 1:
The system performs preliminary actions by detecting driver operations (such as steering wheel rotations or accelerator/brake pedal inputs) before the driver actually wants to terminate the parking assist control. By monitoring these preliminary operational cues, the system proactively determines the driver's intent to terminate and automatically cancels the parking assist control, preventing the need for the driver to perform additional specific operations just to terminate the system.
Solution Approach 2:
The parking assist apparatus serves itself by automatically detecting when the driver wants to terminate the control based on operational patterns, and then automatically performing the termination without requiring explicit driver commands. The system monitors its own operational state and the driver's interactions with the vehicle, and when termination conditions are met, it self-terminates the parking assist control, making the system easier to exit.
2Loss of time
If the parking assist apparatus keeps the vehicle in a stopped state while waiting for driver response to the operation request, then the driver has time to perform the shift lever switching operation, but additional specific operations are required to terminate the parking assist control
Solution Approach 1:
The system continuously monitors driver operations and provides feedback by detecting intent to terminate through operational patterns such as steering wheel rotations or accelerator/brake pedal inputs. This feedback mechanism allows the system to understand the driver's desire to terminate the parking assist control and automatically respond by canceling the control, eliminating the need for additional specific termination operations.
Solution Approach 2:
The system detects preliminary operational cues from the driver (steering wheel rotations, accelerator/brake inputs) that indicate the driver's intent to terminate the parking assist control before the driver actually performs any termination action. By detecting these preliminary actions, the system can proactively terminate the parking assist control, saving time and reducing the number of operations required.

AI summary
A parking assist apparatus is configured to execute parking assist control including steering angle automatic control, driving force automatic control and braking force automatic control, the parking assist apparatus being programmed to notify an occupant of an operation request requesting a driving operation of the vehicle to be performed for the parking assist control; and terminate the parking assist control and notify the occupant that the parking assist control is terminated when the driving operation corresponding to the operation request has not been performed by the occupant within a predetermined period.
