What is a dual-circuit braking system?

The so-called double-loop braking system means that once the braking system of a car breaks down somewhere during driving, this double-loop braking system will not cause the braking performance to decline, which can effectively prevent braking failure, avoid traffic accidents and remind maintenance in time. The double-loop braking system is the engineering foundation of the "brake priority system" that we often hear recently. That is to say, when the accelerator pedal and brake pedal are depressed at the same time during normal operation, the trip computer needs to give priority to the braking signal, that is, while maintaining the normal output of the braking system, reduce the throttle opening, delay the ignition advance angle and reduce the fuel injection amount of the nozzle, so as to quickly reduce the output torque of the engine and ensure effective braking deceleration.
