Embodiment Construction

[0029] The implementation method of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] The invention uses the NFC technology based on the Android system to further optimize the application of wireless communication in automotive electronics. Use NFC for short-distance data exchange, quickly establish a connection, and pass some necessary parameters when connecting two Bluetooth devices to enable the Bluetooth function. The invention makes it easier for users to carry items, and only one smart phone is needed to complete all functions; at the same time, it can also save the pairing steps between Bluetooth devices, so that the vehicle-mounted terminals can be connected quickly with Bluetooth; and the NFC communication distance is short The characteristics also improve its safety.

[0031] The connecting device is a handheld terminal A including NFC and Bluetooth modules and a multimedia vehicle terminal B...

Abstract

The invention discloses a scheme for optimizing an automotive electronics application by utilizing NFC (Near Field Communication) and an implementation method of the scheme, an NFC module of a handheld terminal A works under a point-to-point slave mode, and the NFC module arranged on a vehicle-mounted terminal B continuously sends a radio frequency signal in a polling manner under a point-to-point host mode; a user carries the handheld terminal A to be close to an automobile, at this time, the radio frequency signal excites the handheld terminal A provided with the NFC module in the radio frequency range, a sender starts communication under a certain protocol frame by appointment, and a receiver responds at the same transmission speed by utilizing load modulation data. According to the scheme and the implementation method thereof, the characteristic of simple NFC connection operation and the advantage of quick Bluetooth transmission speed are combined, so that the security of a system is maintained while the performance is better. According to the whole scheme, the user experience is improved and the scheme more conforms to the trend of automotive electronics intelligence.

Description

technical field [0001] The invention relates to the technical field of automotive electronics and wireless communication, in particular to a method for combining NFC technology with modern mature automotive electronics technology. Background technique [0002] As people put forward higher requirements for the intelligent experience of automobiles, the field of automotive electronics is undergoing continuous development, further promoting the application of electronics and communications in the automotive field. The more common technologies for modern automotive electronics applications are Bluetooth technology for car phones and car audio players, and RFID technology for keyless entry. [0003] Bluetooth technology is a short-range wireless communication technology, and the use distance is generally about 10m. Due to its strong anti-interference ability and high communication efficiency, it is used in car phones and car audio players. However, Bluetooth technology also has...
