A sensor unit manufacturing method includes: a core metal insertion process of inserting a core metal member having a length dimension smaller than a length dimension of a core metal accommodation portion into a predetermined location (a section of a curving portion) extending along a longitudinal direction of the core metal accommodation portion; and a bending process of bending the section (the section of the curving portion) of a fixation base portion, into which the core metal member is inserted, following a curved shape of a sensor bracket.

Sensor unit manufacturing method

A vehicle opening and closing apparatus that opens and closes an opening and closing body provided on a vehicle includes: an electric motor that drives the opening and closing body; a position detection part that detects a position of the opening and closing body; a measurement part that measures a current value which flows in the electric motor when the opening and closing body arrives at a predetermined position; a counter that counts up a count value based on the current value; and a determination part that stops, for a predetermined period of time, the next and subsequent opening and closing operation of the opening and closing body when the count value exceeds a first threshold value.

Vehicle opening and closing apparatus

An opening-closing body control device is provided, including a switch unit provided between a power supply device and a drive source, a control unit configured to electrically connect or cut off the connection between the power supply device and the drive source by controlling a conductive state or a cut-off state of the switch unit, a voltage restriction unit configured to restrict a generated voltage of the drive source generated when the drive source is rotated by an external force to a predetermined voltage in a case in which the connection between the power supply device and the drive source is cut off, and a current detection unit configured to detect a generated current output from the drive source when the generated voltage is restricted to the predetermined voltage, wherein the control unit electrically connects the power supply device to the drive source by controlling the switch unit to be in the conductive state in response to the generated current being detected.

Opening-closing body control device

A tubular housing, a motor part that is provided in the housing, and an end damper and a damper member, one of each is provided on opposing ends of the motor part in an axial direction of the motor part and absorbs vibration, wherein the motor part is supported in a floating state by the housing via the end damper and the damper member.

Actuator for a vehicle-door

Provided is a control device for an opening and closing member configured to drive a driving source of an opening and closing member that opens and closes an opening section of a vehicle, and the control device for an opening and closing member includes a power generation detector configured to detect power generation of the driving source, and a controller configured to control driving of the driving source, wherein the controller is changed to a sleep state upon stoppage of the opening and closing member, and is activated from the sleep state to control a braking of the driving source when the power generation detector detects power generation of the driving source.

Control device for opening and closing bodies

A vehicle door opening/closing actuator includes a tubular housing, a motor part accommodated in the housing, a feeding apparatus accommodated in the housing and that supplies power to the motor part, and a closed-bottom tubular seal section that has a circumferential wall arranged to be interposed between an inner circumferential surface of the housing and an outer circumferential surface of the feeding apparatus, and that is arranged to cover the feeding apparatus with an entire thereof, wherein a rib extending in a circumferential direction is formed at an inner circumferential surface of the circumferential wall of the seal section, and a concave section that receives the rib is formed at the outer circumferential surface of the feeding apparatus.

Actuator and vehicle door opening/closing actuator

An actuator includes a yoke having an inner circumferential surface; an armature including a rotary shaft provided inside the yoke; a drive shaft configured to be driven to rotate when receiving a rotating force from the rotary shaft; a cylindrical first housing; a second housing relatively movable with respect to the first housing; a speed reduction gear part is disposed between the rotary shaft and the drive shaft; and a driven member is connected to the drive shaft for moving in an axial direction of the drive shaft in response to rotation of the drive shaft. The yoke is disposed within the first housing and a damper member is disposed between the first housing and the speed reduction gear part.

Actuator for opening and closing a vehicle door

When a main switch () is in an on-state, a controller () allows an electric motor () to drive a sliding door to open and close an opening, and when the main switch () is in an off-state and a half latch switch () is in an on-state, the controller () performs a braking control to allow the electric motor () to generate a braking force. When the main switch () is in the on-state, the sliding door can be opened and closed automatically. When the main switch () is in the off-state and the sliding door is closed manually, the improperly-closed state detecting switch is switched on before a full-latch state, the controller performs a braking control of the driving source. In this manner, damage to components caused by the inertial force of the driving source which results from an abrupt stop of the opening and closing unit can be certainly prevented without enhancing the rigidity of a casing, etc.

Control apparatus for opening and closing unit for vehicle

A motor control device to control rotation of an electric motor configured to conduct opening/closing of an opening/closing body provided in a vehicle includes a control unit configured to generate a regenerating brake force to the electric motor until a predetermined time passes, in a case where it is determined that the opening/closing body reaches a full open position.

Motor control device

In an opening/closing body control device, catching determination part () determines whether or not a catching in an opening/closing body has occurred based on a value of current that flows in a motor; a plurality of sensors (to) disposed to be shifted by predetermined electrical angles detect positions of magnetic poles of the motor (); a counterclockwise pattern storage unit () stores a counterclockwise pattern which is a pattern corresponding to outputs of the plurality of sensors (to) and a predetermined shift in the electrical angles; and drive command part () controls the drive circuit () using a clockwise pattern or the counterclockwise pattern based on the outputs of the plurality of sensors (to), and in a case where the catching determination part () determines that a catching has occurred, controlling the drive circuit () in a predetermined pattern for eliminating the catching.
