Solution Overview

Problem

Existing vehicle control systems fail to effectively prevent mistaken operations on the shift position by vehicle occupants during automated driving, as they do not detect or prevent shifts while automated driving is in progress.

Innovation Solution

A vehicle control system that includes an automated driving controller, an operation reception section, and an operation controller to limit or prohibit shift position operations during automated driving, using a shielding mechanism to hide the shift lever and detect any attempts to operate it, and switching back to manual driving if the shift lever is exposed during automated driving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If automated driving is executed without detecting shift lever operations, then automated driving control can be implemented, but mistaken operation of the shift lever by vehicle occupants may occur

Engineering Contradiction:

Improveautomated driving controlVSAvoidshift lever operation accuracy

Core Design Contradiction:

Extent of automationVSReliability

Solution Approach 1:

The system performs preliminary detection of shift lever operations before they can cause harmful effects. The operation detection section continuously monitors for shift lever operations during automated driving, and when detected, the system immediately transitions to manual driving mode, preventing mistaken operations from taking effect

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where the operation detection section continuously monitors shift lever operations and provides real-time information to the automated driving controller. When an operation is detected, the controller responds by switching to manual mode, creating a closed-loop control system that prevents harmful mistaken operations

Inventive Principle:

Principle #23Feedback

2Ease of operation

If shift position operations are allowed during automated driving, then ease of operation is maintained, but unintended shift lever activations may occur

Engineering Contradiction:

Improveshift position operation accessibilityVSAvoidmistaken shift operation

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The operation detection section acts as an intermediary between the shift lever and the transmission system. It monitors all shift lever operations during automated driving and intercepts unintended activations by triggering a mode switch to manual driving, preventing harmful operations from reaching the transmission

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A vehicle control system includes an automated driving controller configured to execute automated driving of a vehicle by automatically performing at least one of speed control and steering control of the vehicle, an operation reception section configured to receive an operation to switch a shift position of the vehicle, and an operation controller configured to limit reception, by the operation reception section, of the operation to switch the shift position while the automated driving is being executed by the automated driving controller.
