An energy charge controller for controlling electrical energy of a vehicle includes an estimation module and a control module. The estimation module includes a driver behavior judgment unit, a charge curve adjustment unit and an energy charge evaluation unit. The driver behavior judgment unit is configured to generate and output a driving mode signal. The driving mode signal is evaluated to generate a brake charging target datum by the charge curve adjustment unit. The brake charging target datum and a vehicle speed are evaluated to generate a chargeable braking energy value by the energy charge evaluation unit. The control module is configured to store a plurality of situational conditions, and select and output one of the situational conditions to the vehicle by comparing the chargeable braking energy value and a recoverable storage power value from an energy storage device.

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.

A battery characteristic determining device includes a control module and a processing module. The control module outputs a control signal when a battery module is in a charging state and an SOC (state of charge; of the battery module reaches a predetermined target value, so as to result in change of a current of the battery module to a predetermined test value for a predetermined test time period. The predetermined test value is such that the change of the current causes a voltage of the battery module to decrease in the predetermined test time period. The processing module obtains a voltage variation of the battery module in the predetermined test time period, and a C rate of the battery module with reference to the voltage variation.
