Abstract: 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.

Abstract: 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.

Abstract: A flexible strain sensor comprises a sensing area, a connection area, an encapsulation layer and a flexible substrate. The sensing area and the connection area are made of the same conductive material by adjusting size structures of different areas. The sensor is prepared by performing one-step printing of carbon black-silicone rubber composite conductive paste on a fabric substrate on the basis of a screen printing process. The method is simple and convenient to operate, is low in manufacturing cost and is suitable for large-scale production; and the prepared sensor has a high sensitivity (?10), a large strain range(˜100%), a low hysteresis quality and a good stability, and can be applied to the fields of human body motion detection, intelligent medical service, etc. The method for preparing a sensor in the present invention has important reference value for industrial production of a flexible strain sensor.

Abstract: A vehicle diagnosis method, a server and a diagnosis device are provided.

Abstract: A virtual reality haptic feedback interaction system, comprising a head display module, a storage module, an electrical stimulation device, a time-division multiplexing circuit, and a flexible electrode array connected in sequence. The storage module receives haptic feedback parameters corresponding to virtual scene interaction events, and converts the corresponding haptic feedback parameters into corresponding electrical signals through its drive circuit; the electrical stimulation device controls the output pulse parameters of each electrical stimulation channel according to the received electrical signals. The time-division multiplexing circuit selects the optimal stimulation paradigm for each haptic experience, and outputs the corresponding pulse to the flexible electrode array.
