An abnormal detecting system for a pneumatic brake includes a pedal stroke sensor, a front chamber pressure sensor, a rear chamber pressure sensor, a storage unit pressure sensor, a parking brake switch and an abnormal detecting circuit. A pedal stroke signal, a front chamber pressure signal, a rear chamber pressure signal, an air storage unit pressure and a parking brake control signal are output. The abnormal detecting circuit receives the pedal stroke signal, the front chamber pressure signal, the rear chamber pressure signal, the air storage unit pressure signal and the parking brake control signal. The abnormal detecting circuit compares the pedal stroke signal with the front chamber pressure signal or the rear chamber pressure signal and then outputs a first abnormal signal; and the abnormal detecting circuit compares the parking brake control signal and then outputs a second abnormal signal.

An autonomous braking system includes a detecting module, a tracing module, a collision path prediction module, a memory register, a collision time prediction module and a decision module. The detecting module recognizes multiple objects located ahead of a vehicle, and then the tracing module traces the moving objects. The collision path prediction module is used to obtain a possible collision range and a non-collision range. The memory register records the coordinate of the objects located within the possible collision range. When one of the objects moves out of the possible collision range, its data is instantaneously removed from the memory register. The collision time prediction module predicts a collision time between the vehicle and each of the objects. The decision module determines if a brake assist is activated in accordance with the collision time.
