Abstract: An ECU executes a program including the steps of: when a DC/DC converter is boosting the voltage, calculating a VB estimate value, and if a state, where an absolute value of a difference between the VB estimate value and a VB value sensed by a VB sensor is at least a voltage threshold value X, has been continuing for a predetermined time, determining that the VB sensor is tentatively abnormal; if a state, where an absolute value of a difference between a VH voltage instruct value and a VH value sensed by a VH sensor is at least a voltage threshold value Z, has been continuing for a predetermined time, determining that the VH sensor is tentatively abnormal; and if the sensor is tentatively abnormal, stopping boosting, and specifying the abnormal sensor based on the deviation of the VB value and the VH value.

Abstract: When an ignition key is turn ON, an ECU drives a bidirectional DC/DC converter to charge a capacitor to a voltage Vth1. The ECU turns on a first relay only and diagnoses whether or not a second relay, which is off, is welded, based on a change in a voltage VL at that time. After the diagnosis on welding, the ECU turns on the second relay, and the capacitor is charged to a voltage level of a main power storage device.

Abstract: To provide an optical module capable of improving the workability for a circuit substrate, in the rear of a shield case (22), a pressing portion (27) for holding an FOT (6) is formed to press a back surface of a package portion (9) of the FOT (6). In the rear of the shield case (22), a stress countermeasure portion (28) is formed to distribute or mitigate a stress occurring due to deformation and displacement of the pressing portion (27). The stress countermeasure portion (28) is formed between the pressing portion (27) and a substrate connection portion (16). The stress countermeasure portion (28) is formed in the vicinity of the pressing portion (27). In a small space between a base (or bend portion) of the pressing portion (27) and the stress countermeasure portion (28), the force in a twist direction acts due to the occurred stress. This force is distributed or absorbed according to presence and shape of the stress countermeasure portion (28).

Abstract: For providing a removable electrical connector to be attached and removed easily without being damaged, a structure of the removable electrical connector has a receiving part, a pivoting part, an engaging and disengaging part, and a rotation allowing part. The removable electrical connector is pivoted around a first edge of the connector housing of the pivoting part. A second edge opposed to the first edge of the removable electrical connector of the engaging and disengaging part is engaged with and disengaged from the receiving part of a mating connector or a mating equipment. The rotation allowing part allows the removable electrical connector to rotate around the pivoting part.

Abstract: An elastic portion (24) is provided at a bottom surface of a fitting hole (22) formed in a housing (21) of a female connector (20). When a housing (31) of a male connector (30) reaches a reference position (B) during a connector-fitting operation, a bottom surface of the housing (31) contacts a distal end portion (24b) of the elastic portion (24), and presses and displaces this distal end portion (24b) downward. Because of a reaction force produced as a result of this displacement, the elastic portion (24) keeps on urging the housing (31) of the male connector (30) in a direction (upward) of fitting of a lock portion (33) into a lock portion-retaining portion (33).

In the structure, the shield terminal includes a bottom par, a pair of half-box parts on both sides of the bottom part and a pair of press-fitting pieces for the braided wire. The parts are capable of plastic deformation to their closing position where their opposing end faces come into contact with each other. By closing the box part, an inner housing, an inner terminal and a part of exposed braided wire are covered with the shield terminal, while the braided wire is press-fitted to the pair of press-fitting pieces.

Abstract: A motor torque control device of an electric vehicle sets creep torque in accordance with a vehicle speed sensed by a vehicle speed sensor, and sets acceleration torque in accordance with an accelerator control input sensed by an acceleration sensor. Then, the motor torque control device calculates a torque command value by adding the creep torque to the acceleration torque. It is therefore possible to quickly raise the acceleration torque immediately when an accelerator is operated to start the vehicle. It is also possible to prevent a sharp decrease in the torque command value since the torque command value reflects the creep torque even after the start of the vehicle.
