Control system integrated on steering wheel and based on Bluetooth technology

Abstract

The invention discloses a control system integrated on a steering wheel and based on the Bluetooth technology, which comprises a Bluetooth wireless signal transmission circuit and a Bluetooth wireless signal receiving circuit. The Bluetooth wireless signal transmission circuit comprises a keyboard, a keyboard control circuit, a controller module, a Bluetooth wireless signal transmission module, a voltage converter and a battery, and the Bluetooth wireless signal receiving circuit comprises a Bluetooth signal receiving module, a controller module, an eight-path D-type latch, a decoder, a controller expanding module, a liquid crystal display circuit, a controller area network (CAN) bus control module and a CAN bus driving module. The control system integrated on the steering wheel and based on the Bluetooth technology leads most operations commonly used in a driving process to be achieved conveniently on the steering wheel, overcomes defects for looking for switches through head dropping in a traditional driving process, simultaneously leads operations of an automobile electronic control system to be more convenient by using the Bluetooth wireless transmission technology.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a control system integrated in a steering wheel based on bluetooth transmission technology for automotive electronic systems. Background technique [0002] High-tech applications have changed people's lives. While the car is a basic vehicle, people hope that the driving operation of the car will be simpler and more convenient, and that the car can communicate with the outside world in a timely manner. Bluetooth technology can provide technical support for the realization of this new type of automotive electronic information system. Using Bluetooth technology, various electronic devices on the car can be connected wirelessly to form a "vehicle area network". These devices include automotive electrical control equipment , audio and video equipment, vehicle positioning and monitoring equipment, various sensors and their control systems, vehicle security systems and vehicle navig...

AI Technical Summary

Problems solved by technology

[0004] At present, the simplification of the steering wheel control panel has been applied. Domestic and foreign automobile design engineers have begun to simplify the switch to the steering wheel. However, the simplification of the steering wheel control panel is only limited to the application of car audio and cruise systems, and has not yet been applied to other car button switches. , and Bluetooth technology has not been applied to the simplification of the steering wheel control panel
