    摘要： A controller of a vehicle internal combustion engine that is automatically stopped and restarted under a prescribed condition related to operation of the vehicle is disclosed. The engine includes an output shaft, a starter constantly meshed with the output shaft, and a throttle valve regulating the intake air amount supplied to the engine. After the engine has been subjected to an automatic stopping procedure, the controller restarts the engine when a restarting condition is met, and the controller uses the starter to restart the engine if the engine speed is in such a predetermined range that autonomous operation of the engine cannot be restored. The controller predicts, as a predicted air amount, the amount of air drawn into the cylinder of the engine after the restarting condition is met. The controller reduces an engine start fuel injection amount, which is calculated when the starter is used, in correspondence with the predicted air amount.

    摘要： An ECU 30 executes ignition timing retarding control for retarding ignition timing in relation to idling ignition timing at the start of an engine. Also, during the execution of the ignition timing retarding control, on condition that an engine speed NE becomes less than or equal to an idling target speed NEidle and the difference ΔNE of these values becomes greater than or equal to a predetermined value ΔNEstpx, the ECU 30 stops the ignition timing retarding control and executes an ignition timing advancing control for advancing the ignition timing. When a coolant temperature THW is higher than or equal to a predetermined temperature THW1, the ECU 30 stops fuel injection on condition that the engine speed NE becomes greater than or equal to a predetermined speed NEcut. Further, if the coolant temperature THW is higher than or equal to the predetermined temperature THW1, the ECU 30 sets the predetermined value ΔNEstpx for stopping the ignition timing retarding control to a larger value than in a case where the engine temperature THW is lower than the predetermined temperature THW1.

    摘要： A controller (40) of a vehicle internal combustion engine (10) that is automatically stopped and restarted under a prescribed condition related to operation of the vehicle is disclosed. The engine (10) includes an output shaft (11), a starter (20) constantly meshed with the output shaft (11), and a throttle valve (12) regulating the intake air amount supplied to the engine (10). After the engine (10) has been subjected to an automatic stopping procedure, the controller (40) restarts the engine (10) when a restarting condition is met, and the controller (40) uses the starter (20) to restart the engine (10) if the engine speed is in such a predetermined range that autonomous operation of the engine (10) cannot be restored. The controller (40) temporarily opens the throttle valve (12) on the condition that the engine speed at the time when the restarting condition is met is not zero and is in the predetermined range.

    摘要： An ECU includes a backup RAM which stores a learning value of a loss torque characteristic of an engine. The learning value is updated based on the loss torque characteristic which is computed based on an actual engine rotation behavior. The ECU includes a first learning portion (S109) for updating the learning value based on the learning value stored in the memory (Tloss) and a presently computed loss torque characteristic (Tg), and a second learning portion (S112) for updating the learning value based on the presently computed loss torque characteristic (Tlossg) without using the learning value stored in the memory. A switching portion (S107) switches between the first learning portion and the second learning portion in order to update the learning value (Tloss).
