Solution Overview

Problem

Existing driving assistance technologies fail to inform drivers clearly about the reasons for non-performance of assistance controls, leading to driver anxiety.

Innovation Solution

A driving assistance apparatus that determines and informs drivers about the 'operating', 'standby', and 'interruption' states of assistance control based on multiple conditions, including target recognition, first and second conditions, using sensors and display controllers to provide clear visual and audio feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a uniform image displaying non-operating state is shown, then the display system is simple, but the driver cannot understand why assistance control is not performed causing anxiety

Engineering Contradiction:
Improveinformation about assistance control stateVSAvoiddisplay system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the assistance control state information into three distinct types: operating state, standby state, and interruption state. Each state is displayed with a different image or visual indicator, allowing the driver to understand the specific reason why assistance is not provided. This segmentation resolves the contradiction by providing detailed information without requiring a completely complex new display system,而是通过分类显示不同状态图像来实现

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements feedback by continuously monitoring the assistance control state and providing real-time visual information to the driver about why assistance is not operating. The display controller adjusts the displayed image based on the current state (operating/standby/interruption), giving the driver actionable information to understand system status and respond appropriately, thereby reducing anxiety while maintaining manageable system complexity

Inventive Principle:
Principle #23Feedback

2Measurement precision

If multiple conditions are required for assistance control, then the control precision is improved, but the driver cannot understand why assistance is not provided in the same situation

Engineering Contradiction:
Improveassistance control condition judgment precisionVSAvoidinformation about non-operating reason
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent segments the multiple control conditions into two categories: first conditions (target recognition, distance, relative speed) and second condition (driver operation state). By evaluating these conditions separately and determining the specific state (operating/standby/interruption) based on which conditions are met, the system maintains precise control judgment while providing the driver with clear information about why assistance is not provided through differentiated display images for each state

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display controller acts as an intermediary that translates the complex multi-condition evaluation results into simple, understandable visual states for the driver. Instead of showing raw condition data or system internal states, it converts the evaluation outcome into three intuitive display states that communicate the reason for non-operation without revealing complex control logic, thus maintaining both precision and information clarity

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A driving assistance apparatus is configured to perform an assistance control of assisting in driving a vehicle, when a first condition and a second condition are satisfied, in a situation in which a target is recognized. The driving assistance apparatus is provided with: a determinator configured to determine a state of the assistance control. The determinator is configured (i) to determine that the state of the assistance control is a standby state if a standby condition is satisfied, wherein the standby condition requires that the first condition is satisfied, but the second condition is not satisfied, in the situation in which the target is recognized, and (ii) to determine that the state of the assistance control is an interruption state if an interruption condition is satisfied, wherein the interruption condition requires that the first condition is no longer satisfied while the satisfaction of the standby condition is continued.
