An electric control device for vehicles capable of updating an old program with a new program includes: a storage unit that stores the old program; a reception unit that sequentially receives a plurality of pieces of division data acquired by dividing difference data, which includes a data section based on a difference between the old program and the new program and a command section used for generating the new program by reflecting the data section on the old program, or difference compression data acquired by compressing the difference data for every predetermined data length; and a restoration unit that executes a restoration process for restoring the new program based on each division data received by the reception unit and the old program, wherein, in a case in which at least a part of the command section and the data section is not included in the division data received by the reception unit, the restoration unit suspends the restoration process and waits for reception of next division data.
