A gas cross-sensitivity analysis method is provided. The method includes, an injection frequency signal is generated from a first gas. A second gas sensing signal is captured from a second gas. Then, the second gas sensing signal is converted to a second gas sensing frequency signal by using Fast Fourier Transform. Further, a sensing peak frequency signal is determined from peak frequency of the second gas sensing frequency signal. The injection frequency signal and the sensing peak frequency signal are analyzed. A gas cross-sensitivity effect can be direct interpretation by a singular indication between the injection frequency signal and the sensing peak frequency signal.

A vehicle positioning method and its system are disclosed. The vehicle positioning method has a camera adapted to be mounted in front of a vehicle, multiple visible marks mounted in a photographing-available range of a camera, and a vehicle positioning system. Each visible mark contains a position information related to a location of the visible mark. The vehicle positioning system receives an image of the visible mark captured from the camera and image-processes the image to read the position information of the captured visible mark. The vehicle positioning system further calculates a distance between the captured visible mark and the vehicle and then further corrects the position information of the captured visible mark to have GPS coordinates of the vehicle.

An adaptive anti-collision method for vehicles has steps of creating multiple driving patterns with each driving pattern corresponding to a vehicle speed, a safe distance and a braking distance parameter, such as longer safe distance configured for faster vehicle speed, and higher vehicle speed or shorter safe distance for different road condition, acquiring dynamic information, such as vehicle speed or acceleration, of the vehicle using sensors on the vehicle, combining the dynamic information and drivers driving behavior to determine a driving pattern through a statistical analysis and a neural network, adjusting control parameters of the vehicle according to the driving pattern for an electronic control unit of the vehicle to issue an alert or activate a braking action according to the driving pattern. Accordingly, the anti-collision method can be adapted to different vehicle speed, road condition and drivers driving habits for adjusting the safe distance and the braking system.

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.
