Abstract

An automobile detection and control gateway interface and a method thereof are provided. The automobile detection and control gateway interface is connected with a controller area network (CAN) formed by a body control module (BCM) and body devices, and pre-stores a plurality of device diagnostic commands and status diagnostic data, so that the BCM performs corresponding actions on specific body devices according to the device diagnostic commands and capture status feedback data transmitted over the CAN by the body devices, and outputs the status diagnostic data matching with the status feedback data for determining the operation status of the body devices or for the externally connected device to acquire. All the device diagnostic commands are transferred through the BCM to avoid interfering with the operation of the CAN and control the external device connected to the BCM, so as to ensure all the body devices are under control.

Claims

1. An automobile detection and control gateway system, comprising:

a controller area network, comprised of a body control module and a plurality of body devices, wherein the body control module actuates the corresponding body device according to a device diagnostic command, and the actuated body device outputs a status feedback data; and

an automobile detection and control gateway interface, connected with the controller area network based on a communication protocol of International Standard 15765-4 (ISO 15765-4) and recording a plurality of status diagnostic data corresponding to the body devices, the automobile detection and control gateway interface serving for outputting the device diagnostic command, so as to command the body control module to control the corresponding body device according to the device diagnostic command, and outputting the status diagnostic data matching with the status feedback data, wherein the device diagnostic command includes the network identifier of a body device, a control data for the body device, and an execution time of the control data, the body control module establishes a direct conversation path with the corresponding body device according to the network identifier and continuously outputs the control data to the body device in the time period specified by the execution time.

2. The automobile detection and control gateway system according to claim 1, further comprising at least one external device connected with the automobile detection and control gateway interface, wherein the external device performs corresponding actions according to the status diagnostic data.

3. The automobile detection and control gateway system according to claim 1, wherein the body control module is further connected with an external device, and the body control module controls an action of the external device according to the device diagnostic command.
