It is a cardinal system, a variation of score and approval voting, and is also known as dis&approval voting, balanced approval voting (BAV), approval with abstention option (AWAO), true weight voting (TWV1), or evaluative voting (EV) (though the latter can also be used for variants with more than 3 values.) It has also been called net approval voting (though this term has a different definition in the context of approval-based committee selection).
