Abstract: Provided are an Ethereum Virtual Machine-based transaction processing method and apparatus, a device, a program and a medium. An implementation scheme includes: acquiring, by a virtual machine instance running in a blockchain node, a to-be-processed transaction request; in a process of executing the to-be-processed transaction request, generating, by the virtual machine instance, a data access request for target access data and transmitting the data access request to an interface module; performing, by the interface module, instruction conversion according to the data access request to determine a blockchain access interface corresponding to a function of the data access request; and calling, by the interface module, the blockchain access interface for a data storage space of a blockchain to access the target access data and feeding back an access result to the virtual machine instance, where the data storage space includes an account space and a contract space.

Abstract: A vehicle control method, a vehicle control apparatus, an electronic device and a self-driving vehicle all relates to the field of self-driving and intelligent transportation technologies. The method includes: when a vehicle is moving, in a case that an occluding object is detected, determining a hard brake speed limit point and a potential collision point according to a planned path of the vehicle and position information of the occluding object; calculating a speed limit value of the hard brake speed limit point based on a distance between the hard brake speed limit point and the potential collision point; in a case that a planned speed of the vehicle at the hard brake speed limit point is less than or equal to the speed limit value, controlling the vehicle to move at the planned speed.
