摘要： A method of manufacturing a switching element is provided. The method including: preparing a semiconductor substrate which includes an n-type drain region, a p-type body region, and a trench penetrating the body region and reaching the drain region; and forming a lateral surface p-type region extending along a lateral surface of the trench below the body region by heating the semiconductor substrate so as to make a part of the body region flow into the trench. The switching element includes: a gate insulating layer covering an inner surface of the trench; a bottom p-type region in contact with the gate insulating layer at a bottom surface of the trench and connected to the lateral surface p-type region; an n-type source region; and a gate electrode provided in the trench.

摘要： A control device of a vehicle power transmission device for the vehicle power transmission device including a line pressure regulating device regulating a hydraulic pressure of a hydraulic fluid discharged from an oil pump to a predetermined line pressure while changing an opening area of a discharge flow passage, and an automatic transmission having a predetermined gear position established by engagement of a hydraulic friction engagement element by using the line pressure as a source pressure, the control device comprising: an abnormality determination portion configured to detect a slip of the hydraulic friction engagement element establishing the predetermined gear position at the time of establishment of the predetermined gear position and, if an input torque at the time of occurrence of the slip is equal to or greater than an abnormality determination value defined in advance based on a torque transmittable at a minimum line pressure by the hydraulic friction engagement element establishing the predetermined gear position, to make an abnormality determination indicative of a possibility of an abnormality causing the output hydraulic pressure of the line pressure regulating device to be the minimum line pressure while the opening area of the discharge flow passage is maximized, the abnormality determination value being defined in accordance with a rotation speed of the oil pump such that the abnormality determination value becomes larger when the rotation speed is high as compared to when the rotation speed is low.

摘要： When an automatic transmission shift start condition is satisfied, an electronic control unit calculates a meter target rotational speed of an engine by adding a correction amount corresponding to the state of a torque converter to a turbine rotational speed corresponding to a post-shift gear stage, and makes a meter display rotational speed follow after the meter target rotational speed, fixes the correction amount to a value obtained at the time of shift start determination, when immobilization conditions including that the shift start condition for a downshift is satisfied and that the engine is driven are satisfied. When actual rotational speed display conditions are satisfied, it can be predicted that differences between an engine rotational speed and a turbine rotational speed before and after shifting are large, and so the electronic control unit sets a current engine rotational speed as the meter target rotational speed or ends the control.

摘要： A control apparatus for a vehicle drive-force transmitting apparatus which includes a gear mechanism and a continuously-variable transmission mechanism and which establishes selectively a first state in which a drive force is transmitted by the gear mechanism and a second state in which the drive force is transmitted by the continuously-variable transmission mechanism. The control apparatus sets a shift-up-action permitted gear ratio of the continuously-variable transmission mechanism, which makes a state-switch-requiring shift-up action is permitted to be executed. When a running speed of the vehicle is not higher than a given value, a predetermined high gear ratio value is set as the shift-up-action permitted gear ratio. When the running speed is higher than the given value, a predetermined gear ratio range ranging from the predetermined high gear ratio value to a predetermined low gear ratio value is set as the shift-up-action permitted gear ratio.

摘要： Under an abnormal determination, when a transmission gear stage is switched, a torque limit value is changed from a value before switching of the transmission gear stage to a value after switching thereof in a period in which this transmission gear stage is switched.
