PURPOSE:To improve the measurement precision for the throttle opening degree by prohibiting the determination of the throttle opening degree based on the signals supplied from the opening degree detectors for double throttle valves and the idle position detectors during the acceleration slip control. CONSTITUTION:Two throttle valves M4 and M5 are installed into an intake passage M2, and the opening degree sensors M7 and M9 and switches M8 and M10 for detecting the standard opening degree (idle opening degree) position are installed for the valves. Each signal of the opening degree sensors M7 and M9 is input into comparator M11, and the lower value is outputted. The difference between the output and the output of the comparator M11 in the operation in which at least one of the switches M8 and M10 operates is calculated by a throttle opening degree determining device M12. When the execution of the acceleration slip control is detected, determination by the throttle opening degree determining device M12 is prohibited by a prohibiting means M13.
