Embodiment approach

[0024] The pins 3 and 4 of the microcontroller 10 are input terminals, which are respectively connected to the input VCC_ON of the ON gear power supply (starting power supply) of the car and the input VCC1 of the normal fire power supply of the car battery terminal (not shown). The input of the car determines the three states of the car, that is (1) when driving normally, both VCC_ON and VCC1 are high; (2) when parking normally, VCC_ON is low and VCC1 is high; (3) fault , both VCC_ON and VCC1 are low. As an implementation, VCC1 is 12V, and VCC_ON is at the same voltage as VCC1 when the vehicle is started. The pin 5 of the microcontroller 10 is also an input terminal, which is connected to the output terminal V_OUT of the power conversion chip U2 and provides the voltage of the output terminal V_OUT of the power conversion chip U2 to the microcontroller 10 .

[0025] The following is a detailed description of the three states of the car, that is, normal driving, normal parking...

Abstract

The invention provides a vehicle gateway and a control method thereof. The vehicle gateway comprises a microcontroller (10) and further comprises a battery (60), wherein the battery (60) is used for supplying the power to the parts in need of the power supply from the gateway; and the microcontroller (10) is used for controlling the battery (60) to supply the power to the parts in need of the power supply from the gateway when the vehicle is in non-working state and for cutting off the power supply of the battery (60) to the parts in need of the power supply after the microcontroller (10) executes the operation. The vehicle gateway and the control method thereof allow the vehicle gateway to continuously execute the operation after the vehicle stops and allow the vehicle gateway to stop after the operation execution is completed, thereby saving electrical energy and improving the performance of the vehicle gateway.

Description

technical field [0001] The invention relates to an automobile gateway and a control method thereof. Background technique [0002] With the development of automobile industry and communication technology, various bus technologies are widely used in automobiles. The different buses of the electronic components in the car need to exchange data, and the internal system of the car sometimes needs to communicate with the external system, which leads to the concept of "automotive gateway". Automotive gateway products with various functions have come out one after another. These gateways are mainly used for protocol and transmission speed conversion when communicating between buses of different protocols. Different protocols are implemented on the physical layer, data link layer and application layer of the OSI reference model. Translate and interpret to enable barrier-free communication between different buses. [0003] Most of the existing car gateways include the integrated use...
