Automated Driving Indicator Lamp Lighting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving enabled vehicles face challenges in ensuring safety and power efficiency, as the automated driving indicator lamp's constant use increases power consumption, while turning it off when parked can lead to abrupt movement recognition issues by pedestrians and surrounding vehicles.
Innovation Solution
Incorporating a lamp controller to switch on the automated driving indicator lamp before departure from a parked or stopped state, using a controlled lighting sequence to alert others of impending movement, thereby enhancing safety and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the automated driving indicator lamp is kept on during automated driving, then the visibility of automated driving state is improved, but the power consumption increases
Solution Approach 1:
The indicator lamp is activated periodically or conditionally rather than continuously. Specifically, the lamp is turned on before departure from parked or stopped states and during automated driving execution, but turned off during prolonged parked states, creating a periodic lighting pattern that balances visibility with power conservation
2Use of energy by moving object
If the automated driving indicator lamp is turned off when the vehicle is parked, then the power consumption is reduced, but the safety is compromised due to abrupt movement recognition issues
Solution Approach 1:
The indicator lamp is activated in advance before the vehicle actually departs from a parked or stopped state. The lamp turns on when the travel control state transitions to automated driving or when departure is imminent, providing advance warning to pedestrians and surrounding vehicles before movement begins, thereby maintaining safety while allowing the lamp to be off during prolonged parked states

AI summary
An automated driving enabled vehicle includes a travel controller, an automated driving indicator lamp, and a lamp controller. The automated driving indicator lamp is configured to be switched on perceptibly from outside the vehicle on the occasion of automated driving. The lamp controller is configured to start a lighting control of the automated driving indicator lamp that has been off, before the vehicle makes a departure by the automated driving, on the condition that the vehicle is about to make the departure by the automated driving from a parked or stopped state with the automated driving indicator lamp off.
