Vehicle Navigation Display for AC Charging Station Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing information providing apparatuses for vehicles do not offer improved user convenience in distinguishing between AC power feeding facilities, particularly for AC option vehicles that may or may not have an optional AC charging module, leading to difficulties in identifying usable AC stands.
Innovation Solution
An information providing apparatus that includes a controller to differentiate between AC power feeding facilities on a map based on the presence or absence of an AC charger in the vehicle, allowing users to selectively display or hide electrical outlet-type AC stands and cable-equipped AC stands, enhancing user convenience by guiding the vehicle to usable facilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all AC stands are displayed on the map without distinction, then the map shows complete information about power feeding facilities, but AC option vehicles cannot easily identify usable facilities
Solution Approach 1:
The patent segments AC power feeding facilities into two distinct categories: AC stands with electrical outlets (first AC power feeding facilities) and AC stands with charging cables (second AC power feeding facilities). This segmentation allows the navigation device to display different types of AC stands differently on the map, enabling AC option vehicles to easily identify which facilities are actually usable while still preserving complete information about all power feeding facilities.
2Device complexity
If AC option vehicles are supported with selective charging module configuration, then vehicle cost and weight are reduced, but the information providing apparatus must adapt to different vehicle types
Solution Approach 1:
The patent implements a dynamic information display system that automatically adapts to different vehicle types. The navigation device determines whether the vehicle is an AC option vehicle or a vehicle with standard AC charging module, and dynamically adjusts the map display accordingly. For AC option vehicles, it distinguishes between outlet-type and cable-type AC stands; for vehicles with standard AC charging modules, it displays all AC stands uniformly. This dynamic adaptation maintains versatility while supporting reduced vehicle complexity.

AI summary
An information providing apparatus is configured to be used in a target vehicle and display power feeding facilities on a map, the target vehicle being configured such that a vehicle-mounted battery can be charged with DC power supplied from outside the target vehicle. The information providing apparatus is configured to display an electrical outlet-type AC stand on the map in a manner of being distinguished from a cable-equipped AC stand, when the target vehicle is a vehicle not including an AC charger and a prescribed first condition is satisfied. In contrast, the information providing apparatus is configured to display the electrical outlet-type AC stand and the cable-equipped AC stand on the map without distinguishing between the electrical outlet-type AC stand and the cable-equipped AC stand, when the target vehicle is a vehicle including the AC charger and a prescribed second condition is satisfied.
