Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0025] figure 1 It is a flow chart of a testing method for upgrading a vehicle controller provided by an embodiment of the present invention, and this embodiment is applicable to the case of testing a remote controller upgrading process. OTA technology completes the update and upgrade of vehicle systems and functions by downloading data from the cloud. During the OTA upgrade process of the vehicle, the flashing data may be unstable or even fail due to various failures. In the development stage of this embodiment...

Abstract

The invention discloses a test method for upgrading a vehicle controller. The method comprises: a telematics processor T-BOX receiving upgrade data from a host computer; a data monitoring simulation device simulating a corresponding fault environment according to a fault injection test instruction; T-BOX Flashing the upgrade data to the target controller based on the failure environment; the data monitoring simulation device monitors the flashing process of the upgrade data from the T-BOX to the target controller and generates test results. By testing the upgrade performance of the controller in the fault environment through the above technical solution, the comprehensiveness of the test and the stability of the controller upgrade are improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of vehicle testing, and in particular to a testing method for updating a vehicle controller. Background technique [0002] With the increasing demand of users for vehicle performance and various functions, the vehicle controller (Electronic Control Unit, ECU) assembly software, electronic circuits, etc. Especially the remote upgrade has become an essential function. In order to ensure the smooth progress of the upgrade function, it is necessary to test the upgrade function of the vehicle controller before leaving the factory. [0003] At present, the test methods for controller upgrades are mainly for the certificate issuance of the controller, signature uploading, signature verification, verification, and smooth installation of data packets downloaded over the air (Over the Air, OTA), so as to ensure The correctness and security of data during the wireless flashing process. However, in practi...
