Abstract: A signal detection circuit is provided, and includes a first processing circuit, a second processing circuit, a third processing circuit, a fourth processing circuit, a first controller, and a second controller. The first processing circuit, the second processing circuit, the third processing circuit, and the fourth processing circuit are configured to perform filtering and voltage regulation on respective input signals. Both an output end of the first processing circuit and an output end of the third processing circuit are connected to an input end of the first controller. Both an output end of the second processing circuit and an output end of the fourth processing circuit are connected to an input end of the second controller. The first controller is communicatively connected to the second controller. In this way, reliability and safety of torque and angle sensor signal detection can be improved.
