Vehicle Control Apparatus Automatic Braking Cancellation Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems may fail to activate automatic braking when a driver performs unusual accelerator and shift lever operations, potentially leading to collisions with obstacles.
Innovation Solution
A vehicle control apparatus that includes an object recognizing block, a braking controlling block, and an operation determining block, which resists cancellation of automatic braking control when the driver performs different accelerator and shift lever operations, ensuring the system maintains braking control even if the driver presses the accelerator pedal and changes the shift lever in unconventional ways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the automatic braking control is canceled when the driver presses the accelerator pedal into a predetermined pressing state, then the ease of operation is improved, but the reliability deteriorates because the automatic braking may not be activated when there is an obstacle object in front of the vehicle due to accidental depressing operations
Solution Approach 1:
The system dynamically adjusts the automatic braking control based on detected driver operations. When unusual operations are detected (accelerator pressing combined with shift lever position change), the system maintains automatic braking control despite accelerator pressing, whereas under normal operations the automatic braking can be canceled by accelerator pressing. This dynamic adaptation resolves the contradiction by making the system responsive to operational context.
Solution Approach 2:
The operation determining block continuously monitors driver operations and provides feedback to the braking controlling block. When the feedback indicates unusual operations (shift lever position change during accelerator pressing), the system adjusts its behavior to maintain automatic braking control. This feedback mechanism enables the system to distinguish between intentional and accidental accelerator pressing, resolving the reliability concern while preserving ease of operation.
2Reliability
If the braking controlling block prohibits cancellation of automatic braking control when unusual operations are detected, then the reliability is improved, but the ease of operation deteriorates because the automatic braking cannot be canceled even when the driver intends to accelerate
Solution Approach 1:
The system dynamically switches between two operational modes: in the first mode, automatic braking can be canceled by accelerator pressing; in the second mode (activated when unusual operations are detected), automatic braking cannot be canceled. This dynamic mode switching resolves the contradiction by adapting the system's responsiveness to the driver's operational context.
Solution Approach 2:
The operation determining block provides continuous feedback about driver operations to the braking controlling block. When feedback indicates unusual operations, the system transitions to a state where automatic braking cannot be canceled, ensuring safety. When operations are normal, the system returns to allowing cancellation, preserving ease of operation. This feedback-driven adaptation resolves the contradiction between reliability and ease of operation.

AI summary
In a vehicle control apparatus, an object recognizing block recognizes an object which is present around a vehicle. In cases where there is a possibility that the vehicle will collide with an object recognized by the object recognizing block, the apparatus performs automatic braking control which brakes the vehicle. If the driver depresses the accelerator pedal in a predetermined depressing state, a braking controlling block cancels the automatic braking control. When an operation determining block determines that there is a driver's predetermined shift-lever position change, with which the driver's predetermined shift-lever position change is carried out during a driver's accelerator pedal depressing operation, the braking controlling block responds to a driver's accelerator depressing operation by not cancelling the automatic braking control or by making cancellation of the automatic braking control more difficult.
