Vehicle Access Control With Direction-Based Authentication Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle access systems struggle to accurately determine the appropriate timing for initiating operations based on a user's approach, particularly for users moving in various directions relative to the vehicle, complicating the ease of entry and exit.
Innovation Solution
A vehicle control apparatus with an approach detection section and authentication section that uses image capturing units to detect and authenticate users within specific detection ranges, initiating image capture and authentication at optimal times based on user proximity and movement direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the image capturing unit is started only when the user approaches within a setting distance from the vehicle, then the authentication timing is delayed for users approaching from the rear, but starting the image capturing unit earlier improves authentication timing
Solution Approach 1:
The detection range is segmented into multiple zones: a first detection range (lateral) and a second detection range (rear). The image capturing unit is controlled differently based on which zone the user is in, allowing optimized authentication timing for each approach direction without requiring a single complex detection system.
Solution Approach 2:
When a user is detected in the second detection range (rear area), the image capturing unit is started in advance even if the user is beyond the setting distance. This preliminary action ensures that authentication can begin immediately when the user enters the authentication range, eliminating delays for rear-approaching users.
2Loss of time
If the image capturing unit is started early for all users, then authentication timing is improved, but energy consumption increases
Solution Approach 1:
The image capturing unit is started in advance only for users detected in the second detection range (rear area), not for all users. This selective preliminary action improves authentication timing for rear-approaching users while avoiding unnecessary energy consumption for users approaching from other directions.
Solution Approach 2:
The control system dynamically adjusts the image capturing unit operation based on user detection location. When a user is in the first detection range, the unit starts when the user approaches the setting distance. When a user is in the second detection range, the unit starts immediately in advance, creating a dynamic response that optimizes both timing and energy efficiency.
3Ease of operation
If a single detection range is used, then the system is simpler, but it cannot respond appropriately to users approaching from different directions
Solution Approach 1:
The detection system is divided into two distinct detection ranges: a first detection range for lateral approaches and a second detection range for rear approaches. This segmentation allows the system to provide direction-specific response optimization while maintaining relatively simple individual detection zones that are easier to implement than a single complex adaptive range.

AI summary
A vehicle control apparatus includes: an approach detection section; an authentication section; and a start control section. The approach detection section detects a person within a rear detection range and a lateral detection range. The rear detection range includes an area in a rear direction of a vehicle. The lateral detection range includes an area within a range different from the rear detection range. The authentication section authenticates a person detected as a user of the vehicle by using an image captured. The start control section starts the image capturing unit when the person detected within the lateral detection range approaches a position closer than a setting distance from the vehicle, and starts the image capturing unit even when a distance between the person detected within the rear detection range and the vehicle is greater than or equal to the setting distance.
