An idling speed control apparatus of the internal combustion engine of a vehicle having an automatic transmission and a rotary converter

摘要

Vehicle control device, comprising: a machine (2); an automatic transmission (5) connected to the engine (2), the automatic transmission (5) including a torque converter (3) connected to the engine (2) and a transmission mechanism (4) connected to the torque converter (3), the torque converter (5) 3) a pump impeller (41) connected to the engine (2) and a turbine runner (43) connected to the transfer mechanism (4); Driving wheels (9R, 9L) to which the power of the engine (2) is transmitted through the automatic transmission (5); a speed detecting device (25) that detects the rotational speed of the turbine runner (43); and an electronic control unit (10) configured to control the engine (2) in such a manner as to increase a rotational speed of the engine (2) when the rotational speed of the turbine runner (43) is not increased; Standard time after the start of the engine (2) elapses, the standard time corresponds to a time to determine whether the torque converter (3) is in a lost drive state.
