The invention relates to a method, a circuit and a device for detecting insulation resistance of a motor controller, the controller and a vehicle, and relates to the technical field of electronic detection. The method includes: acquiring resistance of a first insulation resistor and resistance of a second insulation resistor; the first insulation resistor is a resistor located between a first electrode of the target equipment and a grounding end, and the second insulation resistor is a target resistor located between a second electrode of the target equipment and the grounding end, or an equivalent resistor obtained according to the target resistor and at least one third insulation resistor; and obtaining an insulation resistance value of the target equipment according to the resistance value of the first insulation resistor and the resistance value of the second insulation resistor. By using the insulation resistance detection method provided by the invention, self-detection of the insulation resistance of the target equipment can be realized.
