Claim:
1. A throttle learning control apparatus having an electronic control unit (ECU) comprising at least one processor configured to receive a signal from a throttle opening degree sensor for detecting an opening degree position of a throttle mounted in an automobile, perform, in a normal case, fully closed learning of the throttle implemented during a self-shutoff delay period, set, as a trip, a cycle from a starting point at which an ignition key switch of the automobile is turned on to an ending point at which the ignition key switch is turned off, and perform a first throttle fully closed learning in which fully closed learning of the throttle is implemented when, in the trip after a self-shutoff delay abnormality has been detected, a predetermined condition is established while the engine is operated, perform a second throttle fully closed learning in which fully closed learning of the throttle is implemented when, in the trip after a self-shutoff delay abnormality has been detected, the engine is stopped, and prevent, when the first throttle fully closed learning or the second throttle fully closed learning is completed, both of the first throttle fully closed learning and the second throttle fully closed learning from being performed during a remainder of the trip, wherein the self-shutoff delay period is a period during which power is supplied to the ECU to perform the fully closed learning after the ending point at which the ignition key is turned off, and wherein the self-shutoff delay abnormality is detected when the fully closed learning of the throttle implemented during the self-shutoff delay period is not successfully performed.
