摘要（英）：

The invention discloses a proportional solenoid valve control signal detection method and an apparatus, and a performance test system. The apparatus comprises a Hall detector and a current determination unit. The Hall detector is used for generating a measurement voltage signal of a secondary side compensating circuit according to a detected current signal of a primary side, wherein the detected current signal is a proportional solenoid valve control signal. The current determination unit is used for determining a detected current signal according to the measurement voltage signal. A magnetic balance principle is combined with a Hall effect and is applied in acquisition of proportional solenoid valve signals. Through a compensation current, a detected signal is obtained. Any changes of the detected signal can be detected acutely so that random waveform currents and voltage can be measured, wherein an impulse waveform is included. Performance of the detection apparatus is stable, linearity is good, precision is high and a measurement scope is wide.
