止時制御構造。[Claims for Utility Model Registration] (1) A control valve is inserted into the exhaust system of the engine, and the opening and closing of the control valve is controlled based on at least the engine rotation speed, so that the output characteristics of the engine and the silencing characteristics of the exhaust system are controlled. A controlled exhaust system for a vehicle that variably sets a vehicle is provided with a stop state detection means for detecting a stop state of the vehicle, and an operation state detection means for detecting an operation state of a transmission mounted on the vehicle, Control means is provided for forcibly opening the control valves based on output signals from each of the detection means when the vehicle is in a stopped state and the transmission is in an operating state in which running is disabled. A control structure for a controlled exhaust system for an automobile when the vehicle is stopped, characterized by the following. (2) The control means further forcibly closes the control valve when the transmission is in an operational state in which the vehicle can run after the control valve is forcibly opened. A control structure for a controlled exhaust system for an automobile when the vehicle is stopped according to claim 1.
