Throttle valve control device for on-vehicle internal combustion engine
专利汇可以提供Throttle valve control device for on-vehicle internal combustion engine专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent a sudden change of a throttle valve and stabilize the same, by correcting a reference opening of a throttle valve for an accelerator pedal operating position according to an operational condition to obtain a target opening of the throttle valve, and limiting the target opening between an upper limit and a lower limit with respect to the accelerator pedal operating position.
CONSTITUTION: Detection values from an accelerator pedal operating position sensor 7, an opening sensor 14 of a throttle valve 12 to be driven by a pulse motor 15, a crank angle sensor 18, a vehicle speed sensor 19, a shift position sensor 20, etc. are input to a control circuit 17. According to operational conditions such as idling operation, high attitude operation, engaged condition of an engine power transmission system, vehicle speed, engine speed, engine warm-up condition, etc., the control circuit 17 computes a target throttle valve opening and a throttle valve driving speed, and sets an upper limit opening and a lower limit opening according to an accelerator pedal operating position. The target throttle valve opening is limited within a range between the upper limit opening and the lower limit opening.
