CONTROL APPARATUS OF THE IDLE ROTATION SPEED OF THE INTERNAL COMBUSTION ENGINE OF A VEHICLE WITH AN AUTOMATIC TRANSMISSION AND A TORQUE CONVERTER

摘要

A vehicle control apparatus which includes an engine, an automatic transmission, and drive wheels transmitted with the power of the engine through the automatic transmission, the automatic transmission including a torque converter connected with the engine, a transmission mechanism connected with the torque converter, the torque converter having a pump impeller connected with the engine, and a turbine runner connected with the transmission mechanism, the vehicle control apparatus for a vehicle further including: an input shaft rotational speed sensor that detects the rotational speed Nt of the turbine runner, and a control unit to control the engine to have the rotational speed Ne of the engine raised when a determination condition in which the rotational speed Nt of the turbine runner is not raised even within a standard time T1 lapsed after the engine is started is established.

1. A vehicle control apparatus, comprising:
an engine; an automatic transmission connected with the engine, the automatic transmission including a tortque converter connected with the engine and a transmission mechanism connected with the torque convertor, the torque convertor including a pump impeller connected with the engine and turbine runner connected with the Transmission mechanism; drive wheels transmitted with the power of the engine through the automatic Transmission; a rotational speed detector that detects the rotational speed of the turbine runner; and an electronic control unit configured to, when the rotational speed of the turbine runner is not raised and a standard time lapses after the engine is started, control the engine such that a rotational speed of the engine is raised, the standard time being a time for determining whether or not the torque convertor is in a lost drive state.
