Abstract: A brake system includes a reservoir, a master cylinder module, a brake pedal, a push rod, a first pressure control unit, a second pressure control unit, a first electronic control unit (ECU), a second ECU, and a redundant ECU. The first ECU is configured to control a brake actuator in the first pressure control unit, the second ECU is configured to control a brake actuator in the second pressure control unit, and the redundant ECU is configured to control at least one brake actuator in the first pressure control unit and/or at least one brake actuator in the second pressure control unit.

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.
