The present invention provides a smart helmet falling detection method and a smart helmet. The falling detection method includes following steps: initializing a system, determining a free fall, determining a collision, determining motionlessness, and generating an emergency signal according to a detection result that a motionlessness event occurs within a fourth duration after the collision event occurs. The smart helmet includes a three-axis acceleration sensor and a controller. For the smart helmet falling detection method and the smart helmet provided in the present invention, the acceleration is measured by the three-axis acceleration sensor installed on the smart helmet, and whether a riding falling event occurs is determined by analyzing change of the acceleration, and alarm is given according to the falling event, such that the problem of falling detection and calling for help in a riding process is solved in a targeted manner.

An advanced warning light system in a motorcycle has a brake light comprising a plurality of light emitting diodes (LED) wherein each LED is configured to illuminate a first color when a motorcycle brake is depressed and wherein only a subset of LEDs are configured to illuminate when the motorcycle is decelerating not in response to the brake being depressed. The system further has a controller area network (CAN) bus for transmitting messages, at least one controller configured for monitoring operations of a motorcycle, the at least one controller further configured for transmitting a message on the CAN bus when a monitored operation occurs on the motorcycle, the message comprising data indicating that the vehicle is slowing down, and a CAN bus interface configured to receive the message from the CAN bus and determine if the brake is being depressed or if the motorcycle is slowing down not in response to the brake being depressed, the CAN bus interface configured to transmit a message to illuminate all LEDs on the brake light if the brake is being depressed and configured to transmit a message to illuminate only the subset of LEDs on the brake light if the motorcycle is slowing down for a reason other than the brake being depressed. Additionally, the system has a processor configured for receiving the message from the CAN bus interface, the processor further configured for illuminating the brake light or a subset of the LEDs on the brake light based upon the message received to indicate to a driver following the motorcycle that the motorcycle is slowing down.
