Title: Valve timing control device for internal combustion engine
Inventor: WADA KOJI
IPC: F01L1/34
Filed: 2002-04-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a valve timing control device for an internal combustion engine for preventing the generation of a shock unexpected to a driver just after releasing a lock pin of a cam phase actuator.  <P>SOLUTION: Existence/non-existence xtq of a torque request when starting the lock pin release control is estimated to change a change ratio β of a target phase angle in response to the existence/non-existence xtq of the torque request. When the torque is not requested, a change ratio β2 smaller than that of a case where the torque is requested is set, and a change of a target phase angle θt after detecting release of the lock pin is restricted. The generation of a shock unexpected to a driver when torque is not requested is thereby prevented. When torque is requested, the change ratio is set at a large value β1 to quickly make the target phase angle θt come close to a base target phase angle θmap. With this structure, a response delay of the detected phase angle due to carry- out of the lock pin release control is restricted to the minimum.  <P>COPYRIGHT: (C)2004,JPO
