Auxiliary Battery Charge Control to Prevent Unnecessary Vehicle Wake-Ups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unnecessary power consumption occurs when a vehicle control apparatus is woken up in response to unnecessary requests for auxiliary charge due to conditions such as an open trunk or hood and low battery capacity, leading to repeated wake-ups and discharge of the auxiliary battery.
Innovation Solution
A vehicle control apparatus with a processor that transfers vehicle state information to a battery sensor to determine if auxiliary charge requests are valid, postponing or blocking requests based on trunk and hood states and battery capacity, thereby reducing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle control apparatus is woken up to perform auxiliary charge when the auxiliary battery's state of charge is below the minimum threshold, then the auxiliary battery can be recharged, but unnecessary power consumption occurs when the trunk or hood is open or the main battery capacity is low
Solution Approach 1:
The system performs preliminary checks of the trunk state, hood state, and main battery remaining capacity before initiating auxiliary charge. By evaluating these conditions in advance, the system prevents unnecessary wake-up operations and power consumption while ensuring reliable charging only when appropriate conditions are met.
2Reliability
If the vehicle control apparatus is repeatedly woken up for auxiliary charge when conditions are not favorable, then the auxiliary battery charge level can be maintained, but the auxiliary battery becomes discharged due to repeated power consumption
Solution Approach 1:
The system continuously monitors the auxiliary battery's state of charge and the vehicle's operational conditions (trunk state, hood state, main battery capacity). Based on this feedback, the system intelligently determines whether to initiate auxiliary charge, preventing repeated unnecessary wake-up operations that would cause energy discharge while maintaining reliable charge levels.

AI summary
An apparatus of controlling a vehicle includes a memory, a network interface, and a processor, wherein the processor is configured to transfer information related to a state of the vehicle to a battery sensor that measures a state of charge (SOC) value of an auxiliary battery of the vehicle and to control the battery sensor so that the battery sensor determines whether to transfer a request for auxiliary charge of the auxiliary battery, according to the information related to the state of the vehicle.
