ムの実行管理装置。[Scope of Claim for Utility Model Registration] In an on-vehicle electronic control device using a microcomputer, an interrupt reception means that receives an input of an interrupt process activated based on an engine rotation signal and an input of an interrupt process at predetermined time intervals; Interrupt processing setting means for setting a priority level of interrupt processing at predetermined time intervals higher than a priority level of interrupt processing activated based on an engine rotation signal in response to two types of interrupt inputs; a program execution means for executing an interrupt process with a set high priority level; a rotation detection means for detecting the rotation period of the engine; and when the rotation period of the engine detected by the rotation detection means is equal to or greater than a predetermined value; A program change for changing the priority level of the interrupt processing setting means so that the priority level of an interrupt processing activated based on an engine rotation signal is higher than the priority level of a predetermined interrupt processing activated at predetermined time intervals. An execution management device for an in-vehicle electronic control program, comprising: means.
