PROBLEM TO BE SOLVED: To provide an electronic control device capable of obtaining a correct value as the conversion results of two ADCs.SOLUTION: An electronic control device includes a first ADC and a second ADC. The first ADC is configured to execute AD conversion of an analog signal input via wiring synchronously with a first trigger signal, and the first ADC has a first capacitor. The second ADC is configured to execute AD conversion of the analog signal input via wiring synchronously with a second trigger signal generated in a timing different from that of the first trigger signal, and the second ADC has a second capacitor. Then, the electronic control device is configured to determine whether or not a conversion timing by the first ADC is coincident with a conversion timing by the second ADC, and to, when determining that the conversion timings are coincident with each other, connect only the first sampling capacitor to wiring, and to control the second ADC having a second sampling capacitor unconnected to wiring not to execute AD conversion (S11, S13).SELECTED DRAWING: Figure 2 |
