A Sensorless Control Solution for DCT Oil Pump with BLDC Motor
Bibliographic record
Abstract
<div class="section abstract"><div class="htmlview paragraph">Double Clutch Transmission system becomes more and more popular in vehicles because of the fuel saving performance, cost efficiency and comfortable feeling during gear change. To save fuel consumption and reduce CO2 emissions, pump can be driven by an electric motor for oil pressure on demand. This paper will introduce a technical solution for sensorless control of an electric pump motor used in a DCT system. Oil pressure control is fulfilled by a speed controller of the oil pump motor. Some critical control requirements for the pump motor are short and reliable start-up stage, stable and accurate speed control. This paper will elaborate on the difficulties of oil pump sensorless control, and how to solve these difficulties with minimum electronic hardware. Test results will be presented. In conclusion, the proposed sensorless control strategy can meet application requirements and meanwhile provide a cost-effective and motor parameters-independent control solution.</div></div>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
