  "textContent": "To provide an electronic throttle control system by which it is possible to appropriately control an idle speed even in a configuration wherein use is made of a lower limit value for specifying a lower limit throttle angle for obviating interference of a throttle valve with an intake passage. The electronic throttle control system (10) includes the throttle valve (14) driven by a motor (22), and a throttle position sensor (26) for detecting the actual angle of the throttle valve (14), with the motor (22) driven by an ECU (24) so as to control the angle of the throttle valve (14). The ECU (24) is so configured that a lower limit value of the angle of the throttle valve (14) is initially set at an angle greater than a full closure angle by a predetermined amount. In addition, when a rise in the engine rotating speed from a preset idle speed by not less than a predetermined value is detected during idling in which the angle of the throttle valve (14) is controlled to the lower limit value, the lower limit value is reduced by a predetermined amount, whereby the engine rotating speed is controlled to within a predetermined value from the preset idle speed.",
