Method for vehicle diagnostics, diagnostic connector, and diagnostic device

A method, a system, and a device for diagnosing a vehicle, and a server. The method is applied to a server and includes: receiving vehicle diagnosis request information sent by a vehicle diagnosis device, where the vehicle diagnosis request information includes identity information of a user and a vehicle type; determining whether the user has an authorization of vehicle diagnosis software corresponding to the vehicle type, based on the identity information of the user; returning authorization information, for the vehicle diagnosis device to diagnose a to-be-diagnosed vehicle, if it is determined that the user has the authorization; and returning prompt information to prompt the user to acquire the authorization of the vehicle diagnosis software corresponding to the vehicle type and then to diagnose the to-be-diagnosed vehicle, if it is determined that the user does not have the authorization.

Method, system, and device for diagnosing vehicle, and server

The disclosure provides a data communication method and apparatus, an electronic device, and a storage medium. The method includes: receiving controller area network (CAN) bus data transmitted by a first device; executing a first flow-control based transmission between the first connector and the first device to obtain respective consecutive frame data in multi-packet data from the first device, upon detecting that the CAN bus data is first frame data in the multi-packet data; and transmitting the first frame data and the respective consecutive frame data to a second connector to indicate that the second connector transmits the multi-packet data to a second device through a second flow-control based transmission, when or after executing the first flow-control based transmission between the first connector and the first device.

Data communication method and apparatus, electronic device, and storage medium

Provided are a method for obtaining vehicle diagnosis software, a server and a diagnosis device. In the method, the diagnosis device sends an acquisition request of target diagnosis software to the server based on a target vehicle, where the acquisition request includes a vehicle identification code; the server determines whether the target vehicle has an authorization qualification of the target diagnosis software based on the acquisition request, to obtain a determination result; the server performs an operation based on the determination result. Only the target vehicle with the authorization qualification can download the software, realizing the flexible configuration of the diagnosis device and configuring the diagnosis device based on user's actual requirement to complete the vehicle diagnosis, and reducing waste of resources.

Method for obtaining vehicle diagnosis software, server and diagnosis device

The present disclosure discloses a calibration device for a vehicle Advanced Driver Assistant System, the calibration device includes: a foldable base (), a stand assembly () and a beam assembly (); the foldable base () including a bearing seat () and a plurality of bearing arms () rotatably arranged on the bearing seat (), the stand assembly () is disposed on the bearing seat (); the bearing arms () are able to be folded relative to the bearing seat () in a direction approaching the stand assembly (); the beam assembly () is disposed on a top of the stand assembly () and includes two foldable beams (). The calibration device for the vehicle ADAS can be folded when it is not in use, so that it occupy a smaller space and is convenient to carry, thereby facilitating its storage and transportation.

Calibration device for vehicle advanced driver assistant system
