Embodiment Construction

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0045] The present invention can judge whether it is necessary for the electronic stability control system to continue sending power CAN messages containing vehicle speed information to the power CAN bus according to whether the vehicle body CAN bus enters a dormant state after the vehicle is powered off. The invention can effectively solve the problem in the prior art that the electronic stability control system continues to send messages to the keyless entry / start system after the CAN bus of the vehicle body is powered off, resulting in...

Abstract

The invention provides a dual-network-segment controlling method and system. The method comprises: after the power of an overall vehicle is off, an ESC collects a current vehicle speed and a gateway collects a state of a vehicle body CAN bus; the ESC sends a power CAN message including current vehicle speed information to the gateway by a power CAN bus; if the vehicle body CAN bus does not enter a sleep state, the gateway converts the power CAN message into a vehicle body CAN message and sends the vehicle body CAN message to a PEPS by the vehicle body CAN bus; the PEPS determines whether the vehicle speed information in the vehicle body CAN message is zero; if so, a steering wheel delocking operation is executed; and if the vehicle body CAN bus enters a sleeping state, the gateway sends information of stopping sending of the power CAN message including the current vehicle speed to the ESC by the power CAN bus. Therefore, a problem of unnecessary storage battery power consumption due to data sending by the ESC to the vehicle body CAN bus in a sleeping mode in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of network management, in particular to a dual network segment control method and system. Background technique [0002] In the field of automotive communication system technology, CAN (Control Aera Network, Controller Area Network) bus communication is the most widely used. Its cost is moderate, and the highest transmission rate can reach 1Mbit / s, which can meet the communication needs of most systems and modules. In general, the vehicle CAN bus system is basically divided into two parts: the power CAN bus system and the body CAN bus system. Among them, the power CAN bus system refers to the communication system between the engine and the automatic transmission. The two buses are connected by a gateway to complete the communication routing between the two network segments. [0003] Under normal circumstances, after the power CAN bus is powered off, the nodes of each power CAN network stop CAN communication...
