  • Spark timing control system for a vehicle-driving internal combustion engine
    Patent number: 5331934
    Abstract: A spark timing control system includes an engine state detecting device for detecting a state of an internal combustion engine. A vehicle vibration detecting device serves to detect a vibration of a vehicle in a longitudinal direction with respect to the vehicle. A target vehicle vibration value calculating device serves to calculate a target vehicle vibration value on the basis of one of results of detections by the engine state detecting device and the vehicle vibration detecting device. A control quantity setting device serves to set a control quantity of a spark timing so as to control the result of detection by the vehicle vibration detecting device at the target vehicle vibration value by use of an optimal feedback gain which is determined according to a dynamic model of the engine.
