An electric oil pump for automobile transmission clutch engagement includes: a temperature sensor that measures a temperature of oil supplied to an oil supply destination relating to clutch engagement of an automobile transmission; an oil pump drive motor; a current determination part that determines a current value output to the oil pump drive motor to a predetermined current value determined such that the oil pump drive motor is capable of being driven without stopping in a case where the temperature is equal to or less than a predetermined temperature at which a torque of the oil pump drive motor becomes smaller than a load of the oil pump drive motor; and an oil pump that supplies oil to the oil supply destination by the oil pump drive motor being driven based on the determined current value.

Electric oil pump for automobile transmission clutch engagement, electric oil pump control method for automobile transmission clutch engagement, vehicle, and vehicle electric oil pump for automobile transmission clutch engagement

A control device of a vehicle, the vehicle includes an engine, a hydraulic clutch disposed on a power transmission path between the engine and driving wheels, a starter motor for use in startup of the engine, an electric oil pump device discharging hydraulic oil generating oil pressure supplied to the clutch, and a power supply device supplying electric power driving each of the starter motor and the electric oil pump device. The control device includes a startup control unit that performs starter startup control of starting discharge of the hydraulic oil by the electric oil pump device after determining that output voltage of the power supply device or input voltage of the electric oil pump device is higher than or equal to a fixed voltage after completion of cranking by the starter motor upon startup of the engine using the starter motor.

Control device of vehicle

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

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 control unit controls an electric motor based on position data on a window glass, and controls an opening-closing operation of the window glass. The control unit includes a reverse rotation detector which detects a reverse rotation operation of the window glass, a reverse rotation prevention controller which performs reverse rotation prevention processing of the electric motor when a reverse rotation is detected, and a position data correction unit which corrects position data on the window glass in an initial operation after occurrence of a reverse rotation operation. If a pulse signal associated with rotation of the electric motor is not input in an initial operation after the detection of the reverse rotation operation, the position data correction unit determines that the window glass has reached a top dead center position, stops the motor, and corrects the position data with the position data at that time as an origin position.

Opening-closing body control system and opening-closing body control method

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.

Opening/closing body control device and opening/closing body control method

The control device for a closure member of a vehicle according to the present invention comprises: estimated load calculation means () for obtaining an estimated load from a rotation speed, acceleration, and drive voltage of a DC motor () for driving a closure member (); motor torque calculation means () for calculating a motor torque from the rotation speed and drive voltage of the motor; reference torque calculation means () for calculating a reference torque based on a stationary state of the motor torque; and pinching determination means () for determining a pinching of an object based on the estimated load, motor torque and reference torque, wherein the pinching determination means determines that there is no pinching when at least one of the estimated load and the motor torque is below the reference torque even when the estimated load is greater than a prescribed threshold value.
