Abstract

The invention provides a vehicle-mounted system and a bidirectional communication method. The vehicle-mounted system comprises vehicle-mounted equipment and an intelligent mobile phone, and realizes direct communication between the vehicle-mounted equipment and the intelligent mobile phone by adopting a WiFi (Wireless Fidelity) / Bluetooth technology. The vehicle-mounted system also comprises a portable card, and the vehicle-mounted equipment indirectly communicates with the intelligent mobile phone by a low-power RF (radio frequency) communication technology via the portable card. The vehicle-mounted system provided by the invention also can realize switching between the WiFi / Bluetooth communication mode and the RF communication mode; when a user is closer to a car, the vehicle-mounted equipment directly communicates with the intelligent mobile phone, and the portable card is in a sleeping state; when the user is farther away from the car and the vehicle-mounted equipment cannot detect a WiFi / Bluetooth signal, the vehicle-mounted equipment is activated to connect with the RF of the portable card, and the portable card is notified to establish a connection with the WiFi / Bluetooth of the intelligent mobile phone at the same time, so that bidirectional communication of the vehicle-mounted equipment and the intelligent mobile phone is realized. According to the vehicle-mounted system provided by the invention, a rich man-machine interface and powerful service functions which are difficultly realized by a REK (remote electronics kit) are provided by using an intelligent mobile phone.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle-mounted system and a two-way communication method. Background technique [0002] The remote keyless entry system (Remote Keyless Entry, RKE) has been used as a standard configuration for the configuration of the car and has become an indispensable part of the car. REK is composed of a receiving controller installed on the car and a remote control carried by the user. By pressing the button of the remote control, the user can realize functions such as unlocking, receiving alarms, and lighting up lights. Some of these systems can also realize remote control Car start and car find functions. However, RKE equipment lacks sufficient man-machine interface and system processing capability, and cannot provide various and powerful services. Contents of the invention [0003] In view of this, the present invention provides a vehicle-mounted system and a two-way communication method...
