An opening and closing body control apparatus for a vehicle includes an assist control portion configured to detect an operation of an opening and closing body of the vehicle by an operator or a user and control voltage applied to a motor serving as a drive source which applies a drive force to the opening and closing body during the operation of the opening and closing body by the operator or the user. The assist control portion applies an assist voltage and an offset voltage alternately to the motor to operate an assist control for applying the drive force to the opening and closing body. The assist voltage for rotating the motor at a rotation speed which corresponds to an operation speed of the opening and closing body and the offset voltage being lower than the assist voltage.

Opening and closing body control apparatus for a vehicle

A vehicular opening/closing body control device includes: an opening drive control unit configured to control operation of a drive device configured to drive a vehicular opening/closing body to open the opening/closing body upward; a gravity descent detection unit configured to detect a descent of the opening/closing body opened upward due to gravity, a braking force imparting unit configured to impart a braking force to the opening/closing body whose descent due to gravity is detected; and an opening drive prohibition unit configured to prohibit opening drive by the drive device of the opening/closing body whose descent due to gravity is detected.

Vehicular opening/closing body control device and vehicular opening/closing body control method

A vehicle opening/closing body control device includes: an assist control unit that applies a voltage to a motor which drives an opening/closing body of a vehicle so as to perform an assist opening/closing actuation that assists a manual operation force with respect to the opening/closing body for performing an opening/closing actuation of the opening/closing body; and an actuation finish determination unit that determines whether or not a finish condition of the assist opening/closing actuation is satisfied, based on a change amount of an opening/closing speed of the opening/closing body per unit time, in which the assist control unit stops applying the voltage to the motor in a case where the finish condition of the assist opening/closing actuation is satisfied.

Vehicle opening/closing body control device

An overcurrent protection device has a threshold value for determination of a magnitude of motor current and performs: a first detection of detecting a period, during which the motor current takes a value larger than the threshold value, as a first value; a second detection of detecting a maximum value of the motor current as a second value by frequently detecting the motor current; and a signal formation of forming a motor stop signal based on determination using the first value and the second value.

Overcurrent protection device and drive device having overcurrent protection device

A control device for a vehicle opening/closing body includes an electronic control unit configured to determine whether a prescribed specific operation is performed by a user on a closing switch that is provided in an opening/closing body of a vehicle to cause the opening/closing body to perform a closing operation, the electronic control unit being configured to cause the opening/closing body to perform the closing operation, and to lock the vehicle when the electronic control unit determines that the specific operation is performed.

Control device and control system for vehicle opening/closing body

A control device for a vehicle closure body includes an electronic control unit configured to measure a position of the body, measure a speed of the body, determine an opening or closing direction in which the body is operated by a user, and move the body in the determined opening or closing direction with use of a drive unit when the speed of the body measured at the measured position of the body is equal to or higher than a speed threshold at the measured position of the body.

Control device for vehicle opening/closing body

An opening and closing body control apparatus includes: a first signal receiving unit receiving a first detection signal indicating the presence or absence of contact of a user with an operating portion of an opening and closing body; a second signal receiving unit receiving a second detection signal indicating a movement speed of the body; and a signal output unit outputting a control signal regulating a holding force of the body to a holding force regulating device, wherein the control signal regulating the holding force to a first holding force less than a second holding force is output to the device according to the first detection signal indicating that the contact has been detected, and when the second detection signal indicating that the movement speed body is greater than or equal to a predetermined speed is received when the holding force is the first holding force, the control signal regulating the holding force to the first holding force is output to the device regardless of the first detection signal.
