Abstract: An interrupt handler unit (130) generates a timer interrupt at an interrupt time, and executes an interrupt preparation process. A wait time period measurement unit (142) a measures a time period from completion of the interrupt preparation process to generation of a start request (201) as a wait time period. A time calculation unit (441) calculates a subtraction time period based on the wait time period measured by the wait time period measurement unit (142), and calculates a preparation time period that is the sum of a time period obtained by subtracting the subtraction time period from the wait time period and a processing time period of the interrupt preparation process. The time calculation unit (441) stores a time obtained by shifting back the preparation time period from the time of a next start request (201), as a next interrupt time, in a time storage unit (442).

Abstract: A microcontroller (200) performs first monitoring in accordance with a first monitoring rule when a priority control interruption occurs in a first time partition for execution of general control, and performs second monitoring in accordance with a second monitoring rule when a priority control interruption occurs in a second time partition for execution of safety monitoring. The microcontroller performs safety control in each of cases where a violation of the first monitoring rule occurs in the first time partition, and where a violation of the second monitoring rule occurs in the second time partition.

Abstract: This disclosure relates to a traffic information estimation device and a traffic information estimation method for estimating a time period of switching of a traffic signal display. The traffic information estimation device includes: an acquisition unit (203) acquiring arrangement information indicating an arrangement of vehicles in accordance with a time passage on a road on which a traffic signal is installed; a determination unit (205) determining changes in density of the vehicles by using the arrangement information; and a calculation unit (206) calculating a display change cycle indicating a time period of switching of a display of the traffic signal based on a time interval between the changes in density of the vehicles. According to such a configuration, it is possible to simplify processing to estimate of a change cycle of the traffic signal.
