Vehicle Power Control for Dark Current Blocking in Production Plants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle production plants, the lack of proper dark current blocking control leads to battery discharge, causing production inefficiencies such as reduced UPH, inspection delays, and decreased quality pass rates due to unsatisfied activation conditions.
Innovation Solution
A vehicle control device and method that includes sensors and a power controller to determine activation conditions and selectively block dark current loads based on plant environment and terrain, using modes like first and second plant modes to manage power supply during production processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dark current blocking control is performed only when activation conditions are satisfied, then safety and accident prevention are ensured, but battery discharge occurs in vehicle production plants causing production inefficiency
Solution Approach 1:
The control system dynamically switches between different operating modes (first plant mode, second plant mode, and customer mode) based on the detected environment. In vehicle production plants, the system identifies the plant environment and automatically selects appropriate plant modes that enable dark current blocking control, whereas in normal customer usage, the system uses activation conditions to prioritize safety. This dynamic adaptation resolves the contradiction by allowing productivity improvement in plants without compromising safety in normal operations.
2Productivity
If dark current blocking control is activated in vehicle production plants, then battery discharge is prevented and production efficiency improves, but additional control complexity is required to identify plant environment
Solution Approach 1:
The control system performs self-identification of the vehicle production plant environment using existing sensors and environmental detection capabilities. The system automatically determines whether it is operating in a plant environment or normal usage environment and selects the appropriate mode accordingly, without requiring external configuration or manual intervention. This self-service approach enables the system to improve productivity in plants while adding minimal control complexity.
3Reliability
If activation conditions for dark current blocking are maintained, then battery discharge is prevented, but production line stoppages and inspection delays occur
Solution Approach 1:
The system applies different control strategies tailored to specific operational contexts. In vehicle production plants, the system implements plant modes with relaxed activation conditions that prevent battery discharge while allowing production processes to continue uninterrupted. In normal customer usage, the system maintains strict activation conditions for safety. This localized quality approach ensures battery protection where needed while minimizing production time loss in manufacturing environments.

AI summary
A device for controlling a vehicle includes a sensor that obtains state information of the vehicle, and a power controller which is configured to determine whether an activation condition of a dark current blocking control function is satisfied based on the state information of the vehicle, determines whether a power control mode is selected when the activation condition of the dark current blocking control function is not satisfied, and controls to cut off power supply to a dark current load based on the selected power control mode.
