In an autonomous driving control apparatus, a control unit controls autonomous driving that causes a vehicle to travel along a scheduled travel route. A storage unit stores driving-operation modules. Each of the driving-operation modules is comprised of a modularized set of a sequence of input/output operations used by a corresponding driving operation carried out by the autonomous driving. The control unit determines the scheduled travel route, and determines, in accordance with the scheduled travel route, at least one selected driving-operation module from the driving-operation modules stored in the storage unit. The control unit performs the at least one selected driving-operation module to thereby cause the vehicle to perform the autonomous driving.

In an autonomous driving control apparatus, a control unit communicable with the memory deter mines, upon execution of the autonomous driving, whether it is necessary to update a primary scheduled travel route for the autonomous vehicle toward a destination in accordance with at least one of failure information about the autonomous vehicle and route condition information indicative of a condition of the primary scheduled travel route. The control unit updates the primary scheduled travel route to a new scheduled travel route in accordance with one or more driving operations executable by the autonomous vehicle upon determination that it is necessary to update the scheduled travel route. The control unit controls the autonomous driving of the autonomous vehicle in accordance with the new scheduled travel route.

In an electrical discharge machine that applies a voltage between an electrode and a workpiece to generate electrical discharge, an electrode holder holds the electrode. An ultrasonic motor has a fingertip that comes into contact with electrode holder, and moves electrode holder in a driving direction by moving the fingertip in an annular manner at an ultrasonic-range frequency. A roller bearing guides the movement of the electrode holder in the driving direction. A control circuit controls a position of the electrode in the driving direction by driving the ultrasonic motor, and moves the electrode holder based on an abnormality occurring in resistance against the movement of the electrode holder in the driving direction such that the electrode holder is moved by a movement distance equivalent to when the largest roller element among a plurality of roller elements of the roller bearing rolls and rotates once without sliding or longer.

A steering apparatus controller for an electric power steering apparatus, which includes an electric motor for generating assist torque for assisting steering of a steering wheel and the steering apparatus controller is designed to execute a feedback control of the applied drive voltage to the electric motor based on the detection result of the actual current that flows through the motor. A sensor detects the actual current to produce the detection result. When detecting an abnormal decrease of the drive voltage of the sensor, a voltage controller maintains the applied voltage to the electric motor at the voltage at a predetermined time before the drive voltage abnormally decreased.

Steering apparatus controller for electric power steering apparatus

A control apparatus of an electric power steering system has first to fourth calculators and an abnormality detector. The first calculator calculates an assist current command value, which corresponds to assist force for reducing steering force of the steering wheel, based on the steering torque of the steering wheel. The second to fourth calculators calculate a compensation current command value, which corresponds to compensation force for compensating for movement of the steering wheel, based on the angular velocity of the steering wheel that has been estimated based on the terminal-to-terminal voltage of the motor. The abnormality detector detects an abnormality of the terminal voltages of the motor. When the abnormality detector detects an abnormality, the second to fourth calculators substitute zero for the steering wheel angular velocity and then calculates the compensation current command value.

A vehicle steering apparatus controller that enables a sub-computer having a capacity lower than that of a main computer to recognize computation results in the same control cycle as the main computer. A main computer of the controller computes an auxiliary torque command value of a steering motor based on the torque of a steering wheel and the velocity of the vehicle in a main control routine. A sub-computer of the controller computes a value equivalent to the command value based on the torque and the vehicle velocity in each cycle of a sub-control routine, which is longer than that of the main control routine. The sub-computer includes a first comparison circuit for comparing the command value and the torque in each cycle of the main control routine and a second comparison circuit for comparing the command value and the equivalent value in each cycle of the sub-control routine.

A control apparatus of an electric power steering system has calculating means, controlling means, determining means suppressing means, canceling means. Calculating means calculates an assist current value that corresponds to the assist force based on steering torque of a steering wheel. Controlling means executes assist control of the motor based on the assist current value. Determining means determines an abnormality in the circuit. Suppressing means suppresses the assist control when an abnormality in the circuit is determined. If the determination of an abnormality has continued longer than a predetermined time since the suppression of the assist control, the suppressing means opens relay means that permits electric power to be supplied to the motor. When it is determined that the circuit returns to normal with the assist control suppressed, the canceling means cancels the suppression of the assist control.
