Patent ID: 7567166

Claim:
A method for ensuring the security of a two-wheeled vehicle, said method comprising the following steps: detecting a plurality of parameters of the vehicle including engine running/stopped, tilt, parked/moving, presence of the driver on the vehicle, and geographical localization, determining according to a logic for processing the detected parameters, and the state of at least one enabling/disabling command of a system, a system state taken from the following system states: a theft surveillance state, when the engine is stopped, an accident surveillance state, when the engine is running, a pre-alarm state caused by detecting a movement, a vibration, a shock or a power supply cut, while the vehicle was in the theft surveillance state, or subsequently to the starting of the vehicle, a disabled surveillance state (surveillance off) subsequently to a command for disabling the system, detecting, depending on the state of the system and on the detected parameters, one of the following system states: the theft alarm state, when subsequently to the pre-alarm state, the system has detected a sensitive parameter which is repeated and/or maintained during a predetermined period of time, the accident alarm state when subsequently to the accident surveillance state, the system detects an extended loss of verticality, when passing to one of the “alarm” states, elaborating a message comprising data for identifying the vehicle, its position, and data corresponding to the state of the system as well as telephonically transmitting this message to a remotely located caller or to a surveillance center.
