Problems solved by technology

To keep the external USB interface, the interaction between internal units has to use I2C (bidirectional two-wire synchronous serial bus), UART (Universal Asynchronous Receiver Transmitter, Universal Asynchronous Receiver / Transmitter) or SPI (Serial Peripheral Interface, Serial Peripheral Interface) and other low-speed methods greatly reduce the overall interaction rate and data processing performance of the system

Abstract

The invention relates to the technical field of communication interfaces, and provides a vehicle, a vehicle-mounted multi-controller communication system thereof and a USB concentrator. The USB concentrator at least comprises a first USB interface, a second USB interface and a third USB interface. The first USB interface is used for being connected to a vehicle-mounted main processor, the second USB interface is used for being connected to a vehicle-mounted coprocessor, and the third USB interface is used for being connected to a vehicle-mounted electronic unit with a sub-processor so as to achieve high-speed communication between the electronic unit and the main processor and between the electronic unit and the coprocessor. In this way, high-speed effective communication between the electronic unit and each processor can be effectively ensured, the limitation that an I2C, UART or SPI mode with a low communication rate must be used is avoided, a USB mode with a relatively high transmission rate can be adopted, high-speed interaction of a larger data volume and the processing capability of a system are satisfied, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of communication interfaces, in particular to a USB hub used between vehicle-mounted multi-controllers, a vehicle-mounted multi-controller communication system, and a vehicle using the vehicle-mounted multi-controller communication system. Background technique [0002] With the rapid development of vehicle technology, more and more cars have popularized the use of the Internet of Things function, and with the development of Internet technology and the great abundance of various hardware and application software, the Internet of Things technology has also been greatly developed . The Internet of Things is regarded as the application expansion of the Internet. The essence of the Internet of Things is mainly reflected in three aspects: one is the characteristics of the Internet, that is, the interconnected Internet must be able to realize the interconnection of things that need to be connected to the ...
