摘要： A control apparatus for use in an internal combustion engine system of a motor vehicle equipped with an automatic transmission having therein a lock-up mechanism. There is included a vehicle resonance reducing section for controlling an opening degree of a throttle valve when the motor vehicle is in an acceleration state so as to reduce a vehicle resonance accompanying an operation of the engine. The vehicle resonance reducing section estimates a torque to be required for the engine on the basis of an accel-operating amount due to the vehicle drive and the engine operating state and corrects the estimated torque by using operation variables of the motor vehicle so as to calculate a target throttle opening degree. Also included in the control apparatus is a lock-up control section for compulsorily locking up the automatic transmission when the vehicle resonance reducing section is in operation. That is, the lock-up control is executed when controlling the opening degree of the throttle valve so as to reduce the vehicle resonance. With this arrangement, it is possible to improve the driveability of the motor vehicle by reducing the vehicle resonance concurrently with enlarging the lock-up region to improve the fuel consumption.

摘要： An apparatus for treating fuel vapor, such as in a motor vehicle fuel tank, by subjecting it to adsorption treatment to prevent its direct emission into the atmosphere. The apparatus according to the present invention comprises a fuel tank, a partitioning wall provided within the fuel tank to define a small fuel storage chamber within the fuel tank, a canister container housed in the small fuel storage chamber, the canister container storing therein a fuel adsorbing material. When fuel feeding takes place, feeding fuel is introduced into the small fuel storage chamber to cool the canister container. However, when the engine is operated, high temperature return fuel is introduced into the small storage chamber to heat the canister container thereby promoting the adsorbing and de-adsorbing action of fuel by the fuel adsorbing material.

摘要： A control apparatus for a shift range changeover device determines temporary abnormality, when a detection output of a rotation position of a motor continues to be abnormal for a first abnormality determination period. The control apparatus further determines persistent abnormality and performs predetermined failsafe processing, when the detection output further continues to be abnormal for a second abnormality period following the first abnormality period. If the temporary abnormality is determined within a feedback control permission period, motor feedback control is prohibited to control the shift range to the neutral range. If the temporary abnormality is determined after the feedback control permission period, the same control operation as before the temporary abnormality is performed.

摘要： A shift-by-wire shift switching device and shift switching method that switch a shift range of an automatic transmission using an electric motor. The shift switching device includes a controller that determines whether a fault has occurred in a current supply line of each phase of the electric motor on a phase-by-phase basis, executes an open-loop control of the electric motor using only the phases in which it has been determined that a fault has not occurred, and determines whether a fault has occurred in the current supply line by detecting an activation state of the electric motor when the open-loop control of the electric motor is executed. Therefore, it is possible to determine whether a fault in the motor is a short-circuit fault or a break fault, without addition of a part such as a short-circuit detection sensor.

摘要： An engine ECU executes a program including the steps of: calculating a correlation coefficient K based on the result of comparing a vibration waveform of an engine and a knock waveform model stored previously; calculating a magnitude value LOG(V) from the magnitude V detected based on a signal transmitted from a knock sensor; creating frequency distribution of magnitude values LOG(V) by using magnitude values LOG(V) in an ignition cycle in which the correlation coefficient K larger than a threshold K(1) is calculated; and counting knock proportion KC by using the created frequency distribution. If the vibration waveform includes a waveform of vibration of noise components, the correlation coefficient K is calculated to be smaller comparing with a case of not including it.

摘要： A controlling device includes a range switch mechanism, range switch operating means, operation frequency monitoring means, and heat generation limit controlling means. The range switch mechanism is adapted to change a shift range using a motor. Through the range switch operating means, an occupant inputs a required shift range. The motor is controlled in accordance with the required shift range such that the shift range is changed into the required shift range. The operation frequency monitoring means monitors an operation frequency of the range switch operating means. The heat generation limit controlling means switches a control of the motor to a heat generation limit control when the operation frequency of the range switch operating means exceeds a predetermined frequency.

摘要： A shift control system rotates an actuator to cause a wall of a detent plate to contact a roller of a detent spring, and detects the position of contact so as to detect the position of the wall of the detent plate. This wall position is set as a reference position of the actuator. Accordingly, the rotation of the actuator can appropriately be controlled even if an encoder which can only detect relative positional information is employed, and thus the shift range can appropriately be switched.

摘要： A motor control apparatus controls a motor that drives an output shaft through a rotation transmission system. The difference between a newly established output shaft target rotation angle and a detected output shaft rotation angle is obtained, a target rotation angle for the motor is derived based on that difference, and the motor is driven accordingly. When it is determined, based on the detected output shaft rotation angle, that motor rotation has at least proceeded to a point whereby backlash in the transmission system is nullified, the target motor rotation angle is updated based on the current value of the aforementioned difference.

摘要： A control unit learns at least one limit position in a movable range of an object to be controlled which is driven by a motor, and reduces learning time of a limit position. The control unit rotates the motor until the motor strikes the object against at least one limit position in a movable range of the object to learn the limit position. In the strike control, the control unit drives the motor first by a first duty ratio to increase the rotation of the motor toward the limit position quickly, and then by a second duty ratio lower than the first duty ratio to thereby reduce the impact load generated at the time of collision. In place of the duty ratio, a phase advance amount may be changed to reduce the impact load.
