Abstract

The invention discloses an energy consumption sensing-based high-performance automotive electronic dynamic scheduling algorithm. According to the algorithm, an electronic control unit merging algorithm for the deadline driving of a plurality of dynamic arrival functions is adopted, so that a plurality of dynamic arrivals can satisfy real-time requirements, and the number of function arrivals can be maximized; and a global multi-dynamic function energy-saving algorithm is adopted, so that the energy consumption of functions can be decreased as much as possible.

Description

technical field [0001] The invention relates to the field of automotive electronic control, in particular to an automotive electronic system scheduling algorithm based on an embedded real-time operating system. Background technique [0002] In the OSEK (Open Systems and the Corresponding Interfaces For Automotive Electronics, Embedded Real-Time Operating System) specification, the industry specification followed by the automotive electronic operating system, the management of OS objects such as tasks, events, resources, counters, and interrupts is clearly defined. Note that a standard API interface and parameter types have also been formulated. The embedded real-time operating system can provide rich control strategies according to the actual needs of users. The tasks of the embedded real-time operating system not only maintain relative independence, but also ensure the reliability of the system. Ensure that the system has high real-time performance. Usually, in order to m...
