The utility model relates to the field of
electronic systems, and discloses a keyless entry and one-key start
system, which is characterized in that a
Bluetooth module is used for replacing a traditional LF (
Low Frequency) transmitting module and a traditional RF (
Radio Frequency) receiving module at a vehicle end, and a
Bluetooth module is used for replacing a traditional antenna and a traditional RF transmitting module at an intelligent key end. The intelligent key is in communication connection and
identity recognition with the vehicle end through the
Bluetooth module, and the dilemma that a traditional LF
radio frequency module is prone to being interfered by the external
electromagnetic environment, so that a whole vehicle fails to be unlocked, and a user cannot enter the vehicle is avoided; meanwhile, the Bluetooth module has a
frequency modulation and spectrum spreading technology, and can select a
frequency band with the optimal
signal strength to perform data communication, thereby ensuring the
communication quality, improving the user experience, and providing great convenience for the user to enter and exit the vehicle.
