The present application provides a high voltage interlock detection system for a vehicle, comprising: a plurality of high voltage components, each high voltage component comprising a plug connector; and the low-voltage detection controller is connected with the plug connector of the high-voltage component so as to form a detection loop. The low-voltage detection controller comprises a low-voltage signal source, the low-voltage signal source is used for outputting a PWM signal to enable the PWM signal to be transmitted through the plug connector, and the low-voltage signal source is used for enabling the duty ratio of the output PWM signal to be changed in a preset mode; and the detector is used for receiving the PWM signal transmitted by the plug connector of the high-voltage component and generating a signal representing abnormity when the duty ratio change of the received PWM signal is inconsistent with the preset mode. The invention further provides a detection method.
