Embodiment Construction

[0040] Several concepts that appear in this specification are introduced here.

[0041] Vehicle: generally refers to a car, specifically a traditional fuel-powered car, an electric car or a bicycle driven by other energy sources. It can be a car with driverless functions, or a car that requires the driver to participate in the control to drive.

[0042] User of the vehicle: The driver or passenger of the vehicle.

[0043]Driving navigation system: software or hardware that provides route navigation services for the vehicle during the driving process. The driving navigation system may be installed on the vehicle. For example, many vehicles come with a driving navigation system, and the driver can interact with the driving navigation system through the central control screen of the vehicle. The driving navigation system can also be an application installed on the user equipment (such as a mobile phone, a notebook computer, and a tablet computer) of the vehicle user, such as va...

Abstract

The invention discloses a road condition information acquisition method based on a block chain smart contract. A vehicle-mounted terminal is provided, the vehicle-mounted terminals are deployed on a vehicle, each vehicle-mounted terminal serves as a node to form a block chain network, meanwhile, an intelligent contract is deployed in the block chain network, and the intelligent contract is used for responding to a road condition information acquisition request sent by any vehicle-mounted terminal and matching other vehicle-mounted terminals capable of providing road condition information. Therefore, the other vehicle-mounted terminals can be notified to send the road condition information to the vehicle-mounted terminal needing the road condition information. The vehicle-mounted terminal which obtains the road condition information sent by other vehicle-mounted terminals can provide the road condition information to the driving navigation system of the corresponding vehicle, and the driving navigation system can optimize the driving route based on the received road condition information.

Description

technical field [0001] The embodiment of this description relates to the field of information technology, and in particular to a method for acquiring road condition information based on a blockchain smart contract. Background technique [0002] Currently, the driving navigation system can recommend a driving route for the vehicle according to the departure and destination specified by the vehicle user, and then provide navigation services for the vehicle based on the driving route. [0003] In practical applications, vehicle users often hope that the driving navigation system can optimize the driving route according to the road conditions of the road section the vehicle will drive into during the process of realizing the driving route. For example, in the process of realizing the driving route, the driving route can be adjusted to avoid accident road sections and congested road sections as much as possible. [0004] However, the road condition information obtained by the dr...
