Vehicle Lamp Control for Parking Space Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems lack an efficient method to effectively illuminate and communicate the presence of available parking spaces to both the vehicle and surrounding environment, particularly during the parking process, which can lead to reduced recognition rates of parking spaces and increased accident risks.
Innovation Solution
A vehicle control device equipped with a sensing unit and processor that activates specific lamps in a predetermined illumination mode when the vehicle enters an area adjacent to a parking space, maintaining illumination as it enters the space, and adjusts light output based on the presence of objects or the vehicle's direction, to enhance visibility and recognition of the parking space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If lamps are activated in a predetermined illumination mode when the vehicle enters an area adjacent to a parking space, then the recognition rate of the parking space and ambient brightness are improved, but the energy consumption increases
Solution Approach 1:
The system activates lamps in advance when the vehicle enters an area adjacent to a parking space, before the vehicle actually enters the parking space. This preliminary illumination ensures that the parking space is well-lit for recognition and imaging purposes, while limiting the duration of lamp activation to reduce energy consumption.
Solution Approach 2:
The illumination mode is dynamically adjusted based on the vehicle's position and movement. The system determines whether the vehicle is entering or exiting the parking space and activates or deactivates lamps accordingly, optimizing the balance between recognition rate and energy consumption.
2Reliability
If lamps are maintained in illumination mode after the vehicle enters the parking space, then the visibility and safety are improved, but the duration of action increases
Solution Approach 1:
The sensing unit continuously monitors the vehicle's position and movement state. Based on this feedback, the processor determines when the vehicle has successfully entered the parking space and adjusts the illumination mode accordingly, maintaining lamps only for the necessary duration to ensure safety and recognition.
3Adaptability or versatility
If light output is adjusted based on the presence of objects or vehicle direction, then the adaptability and recognition rate are improved, but the device complexity increases
Solution Approach 1:
The sensing unit automatically detects objects and vehicle direction, and the processor autonomously determines the appropriate illumination mode based on this information. The system serves itself by making real-time decisions without requiring complex external control mechanisms.

AI summary
A vehicle control device includes a plurality of lamps provided on a vehicle; a sensing unit configured to sense information related to the vehicle; and at least one processor. The at least one processor is configured to, based on a determination, through the sensing unit, that at least a portion of the vehicle has entered a first area that is adjacent to an available parking space, activate, in a first illumination mode, at least one lamp among the plurality of lamps that has entered the first area that is adjacent to the available parking space.
