摘要： A driving control device for an electric vehicle includes an electric machine which is driven by a current supplied from a battery, a transmission which is coupled with the electric machine and performs shifting at a predetermined gear ratio, a charging state detecting portion which detects an electric variable that shows a charging state of the battery, a fail determination processing device which determines whether the electric variable exceeds a threshold value and makes a fail determination when the electric variable exceeds the threshold value, and a charging control processing device which decreases a rotational speed of the electric machine and reduces the electric variable when the fail determination is made. The fail determination is made to decrease the rotational speed of the electric machine when field weakening control becomes unperformable and the electric variable exceeds the threshold value, which makes it possible to prevent an overcurrent from being supplied to the battery.

摘要： The clutch oil pressure (PC1) supplied to a hydraulic controller of an automatic transmission is detected. If it is detected that the clutch oil pressure (PC1) is less than or equal to a first threshold value PA when a first oil pump cooperative with a drive power source is to stop, the second oil pump is driven. Therefore, after the oil pressure (for example, PY) remaining from the first oil pump has decreased, the second oil pump is driven, and an oil pressure (PX) needed for the hydraulic control of friction engagement elements is maintained. If it is detected that the clutch oil pressure (PC1) is greater than or equal to a second threshold value (PB) when the first oil pump is to be driven, the second oil pump is stopped. Therefore, the second oil pump is stopped when the oil pressure provided by the first oil pump rises to such a level that the oil pressure (PX) can be secured. Thus, the load on the second oil pump is reduced so as to allow it to be reduced in size.

摘要： The present invention provides a drive control apparatus for driving an electric oil pump by supplying it with a predetermined operating voltage so as to decrease a load on the electric oil pump. The drive control apparatus detects a clutch hydraulic pressure supplied to the hydraulic control apparatus for the automatic transmission and drives the electric oil pump so that a required hydraulic pressure is maintained. In this case, the drive control apparatus detects an oil temperature of the hydraulic control apparatus for the automatic transmission, controls the operating voltage of the electric oil pump based on the oil temperature, and supplies the operating voltage to th electric oil pump. Accordingly, the hydraulic pressure supplied from the electric oil pump maintains the hydraulic pressure required for the hydraulic control of the automatic transmission and prevents supply of a greater hydraulic pressure than is required.

摘要： When a driver depresses an accelerator pedal to request a shift such as a downshift or the like, a maximum shift target changing rate (shift speed) of a CVT having a belt-type continuously variable shift apparatus is set based on the shift inertia of the CVT and the like. An assist torque is set by subtracting the normal torque of an internal combustion engine from a torque needed to achieve the maximum shift target changing rate. The assist torque and the torque outputtable from an electric motor based on the characteristic of the motor are compared. If the assist torque is greater than the motor torque, the target changing rate is restricted by an assist possible rate based on the ratio between the assist torque and the motor torque. The shift of the CVT is controlled by the target changing rate (shift speed). Thus, the apparatus allows a quick speed by assisting with a motor torque and, in a case where the assist torque from the motor is insufficient in quantity, allows a shift at a speed in accordance with the case, thereby resolving the degradation of acceleration feel caused by the shift inertia of the CVT.

摘要： A control system for a hybrid vehicle, by which the starting movement of the vehicle by the motor is like that of the prior art gasoline engine vehicles. The hybrid vehicle includes an internal combustion engine 2 and a motor connected to the engine. The control system comprises: engine torque estimating means MCP for estimating the engine torque mgTorque_eg of the internal combustion engine while being fed with fuel after the fuel feed to the internal combustion engine had been interrupted; and motor driving torque calculating means for calculating motor driving torque mgTorque for driving the motor, on the basis of the estimated engine torque determined by the engine torque estimating means. The motor is driven to follow the estimated engine torque. Even if the hybrid vehicle is started by the motor, therefore, a torque demanded by the driver can be fed to the side of a transmission 5 so that the starting movement can be as if the vehicle were started by the engine 2.

摘要： A motor 12 includes a cylindrical rotor 20, a stator 19 arranged at a predetermined distance from an outer periphery of the rotor 20, and a position sensor 23 for detecting a rotational position of the rotor 20, wherein the stator 19 includes a stator core 19a and a plurality of stator windings 19b arranged along a circumferential direction of the stator core 19a at substantially equal distances from one another. A shield plate 26 for shielding magnetic flux from the stator windings 19b to the position sensor 23 is mounted against the stator core 19a. Magnetic flux from the stator windings pass through a closed loop starting from the stator windings 19b through the stator core 19a and the shield plate 26 and back to the stator windings to prevent the magnetic flux leakage from the stator windings 19b from flowing to another member. With this arrangement, the magnetic flux leakage from the stator windings does not affect the position sensor (magnetic sensor) which detects the rotational position of the rotor.
