Embodiment Construction

[0039] The existing body controller has only one CAN interface, which is connected to a CAN network segment for information exchange, and does not have the CAN gateway function; the vehicle needs to be equipped with a separate CAN gateway controller to realize the information exchange of different CAN network segments; the core of the present invention The idea is to add an SPI-to-CAN module on the basis of the existing body controller to realize the CAN gateway function and avoid carrying a separate CAN gateway controller, thereby reducing the cost of the vehicle, saving vehicle space and reducing power consumption.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, ...

Abstract

The invention provides a vehicle body controller and a control method thereof, which belong to the field of vehicle controllers. The vehicle body controller includes an MCU, an SPI-to-CAN module and two CAN transceivers; the first CAN transceiver is connected to the CAN interface of the MCU, and the SPI-to-CAN The modules are respectively connected to the second CAN transceiver and the SPI interface of the MCU; the first CAN transceiver is used to connect to the first CAN network segment; the second CAN transceiver is used to connect to the second CAN network segment; the MCU performs CAN reporting through two CAN transceivers. The receiving and sending of text realizes the data interaction between two CAN network segments. The vehicle body controller provided by the present invention realizes the CAN gateway function on the basis of realizing the conventional controller function, expands the application range of the vehicle body controller, and can avoid the vehicle carrying a separate CAN gateway controller, thereby reducing the overall Vehicle cost, save vehicle space and reduce power consumption.

Description

technical field [0001] The invention relates to the field of vehicle controllers, more specifically, to a vehicle body controller and a control method thereof. Background technique [0002] At present, there is a lot of vehicle interaction information, and a gateway controller needs to be equipped to realize information interaction and filtering of different CAN (Controller Area Network, Controller Area Network) network segments. Two or more CAN communication modules are integrated in the gateway controller, and message receiving and sending are realized through two CAN communication modules. The existing solution of carrying a separate CAN gateway controller increases the cost, occupies a large space, and increases power consumption. Contents of the invention [0003] In view of this, the present invention proposes a vehicle body controller and its control method, which intend to realize the gateway function, so as to reduce costs, save vehicle space and reduce power con...
