Problems solved by technology

[0003] However, the current test methods for the above-mentioned forwarding signals that need to be forwarded between different CAN buses are still not perfect, or simply test whether the data sent by a node on one CAN bus can be sent to another through the policy controller CAN bus
Therefore, the current test method has the problems of single test method, incomplete coverage and low accuracy.

Embodiment Construction

[0022] 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.

[0023] figure 1 It is a schematic diagram of the transmission of forwarding signals in the related art. Such as figure 1 As shown, the forwarding signal S is sent by the sending node A, with the vehicle controller as the intermediary, sent from one CAN bus (CAN1) to the vehicle controller, and then forwarded by the vehicle controller to other CAN buses. It is used by node B of the CAN2 bus or other nodes on the bus after receiving it. in, figure 1 In the example, the vehicle controller is VCU (Vehicle Control Unit, vehicle control un...

Abstract

The present invention provides a vehicle control unit simulation test method, device and system. The method comprises the following steps: in the current test environment of a vehicle, controlling a first node to send a first signal to a vehicle controller to be tested according to a preset rule to forward the first signal to a second node through the vehicle controller to be tested, wherein the first node is located on a first CAN bus, and the second node is located on a second CAN bus; monitoring a second signal received by the second node, and determining whether the second signal accords with the preset rule or not; and if the second signal accords with the preset rule, determining the consistency of the second signal and the first signal. According to the embodiment of the invention, the test coverage degree is more comprehensive and abundant, and the test accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle controller testing, in particular to a simulation test method, device and system for a vehicle controller. Background technique [0002] At present, most of the vehicle controllers in the vehicle communicate with other nodes on the vehicle through a CAN (Controller Area Network, Controller Area Network) bus, and there are generally more than one CAN bus. If the data sent by a node on one CAN bus needs to be transmitted to another CAN bus, the sending node can send the data to the vehicle controller through the CAN bus where it is located, and use the vehicle controller as an intermediary, The data is forwarded to other nodes of another CAN bus. [0003] However, the current test methods for the above-mentioned forwarding signals that need to be forwarded between different CAN buses are still not perfect, or simply test whether the data sent by a node on one CAN bus can be sent to another through ...
