Electronic throttle drive device and engine control device provided with the electronic throttle drive device

摘要

[PROBLEMS] To improve the startability of an engine while improving the quietness when the engine is stopped. A motor drive frequency change period after power-on is monitored, a function for stopping a throttle motor 5A is added, and when the motor drive frequency is changed, a throttle valve opening Tp is monitored and adjusted. The operation of the starter motor 16, the fuel injection device 8, the ignition coil 11A, and the fuel pump 13 is controlled so that the engine is not driven until the target frequency is reached or until the throttle valve opening Tp reaches the target opening.
