摘要： An object of the present invention is to obtain a controller device for a variable valve timing apparatus capable of controlling a phase to an arbitrary fixed valve timing from immediately before an internal combustion engine stops until after the internal combustion engine has stopped. The controller device for the variable valve timing apparatus according to the present invention performs, during engine stop processing of the internal combustion engine, normal control of changing the relative rotational phase of a camshaft to a most advanced position or a most retarded position when the rotational speed of a crankshaft is equal to or more than a first threshold, and low-speed control of fixing a current or a voltage supplied to the motor to be constant to maintain the relative rotational phase of the camshaft at the most advanced position or the most retarded position in a period from when the rotational speed of the crankshaft is lower than the first threshold until the rotational speed becomes zero.

摘要： An object of the present invention is to provide a vehicle control device capable of ensuring safety without giving a sense of discomfort to a passenger, by appropriately decreasing a target vehicle speed when a vehicle deviates from a target trajectory in order to prompt the vehicle to return to the target trajectory, and quickly resuming the target vehicle speed to an original speed when the possibility of re-deviation is low. A vehicle control device of the present invention is a vehicle control device that performs control for causing a vehicle to travel along a target trajectory at a target vehicle speed, the vehicle control device including: determining whether or not a vehicle 501 is in a deviated state in which the vehicle deviates from a target trajectory 502; calculating, when the vehicle is determined to be in the deviated state, a suppression amount by which the target vehicle speed is decreased based on a deviation amount indicating the deviated state; holding a maximum value of the suppression amount and suppressing the target vehicle speed using a hold value that has been held; and decreasing the hold value of the suppression amount at a predetermined speed when the vehicle returns from the deviated state to the target trajectory and a preset release condition is satisfied.
