Claims

When an overload is detected on the door based on a control result of the door driven by a door driving device that supplies a motor current to a door motor that opens and closes the door of the car according to the input control value. A door overload monitoring unit for manually switching the movement mode of the door;
When the door overload monitoring unit detects that the door is overloaded, the door overload monitoring unit corresponds to a torque value that is balanced by a mechanical door closing force according to the movement amount of the door detected by the movement amount detection unit. A manual torque command generator that outputs a torque command to stop the door and outputs a torque command that compensates for the torque value in accordance with the direction in which the door is manually moved;
A door control device, comprising: a motor current control calculation unit that outputs a control value of the motor current calculated based on the torque command input from the manual torque command generation unit to the door drive device.

The control result of the door is a current feedback value of the motor current output from the door driving device to the door motor,
The door control device,
When the door overload monitoring unit detects that the door is overloaded by a torque feedback value calculated from the current feedback value being equal to or greater than a first threshold value, by the door overload monitoring unit. A door speed command generation unit that generates a door speed command to stop the door,
The door control device according to claim 1, wherein the motor current control calculation unit outputs a control value of the motor current calculated based on the torque command and the door speed command to the door drive device.

The movement amount detection unit detects a door speed of the door as a movement amount of the door,
The door control device,
A door position generation unit that generates a door position of the door based on a speed feedback value indicating the door speed detected by the movement amount detection unit;
An information storage unit that stores a mechanical door closing force corresponding to the door position,
The torque command generation unit, while the torque feedback value is less than a second threshold, according to the door position generated by the door position generation unit, the torque value balanced with the mechanical door closing force, The door control device according to claim 2, wherein the door control device extracts the torque value from the information storage unit and compensates for the torque value while the torque feedback value is equal to or greater than a second threshold value.

The door control device,
Based on the door speed, has a door movement direction monitoring unit that monitors the movement direction of the door,
4. The door control device according to claim 3, wherein the torque command generation unit determines a direction in which the torque value is compensated for in accordance with a movement direction of the door monitored by the door movement direction monitoring unit. 5.

The door overload monitoring unit, while the door is stopped for a predetermined time or more, when detecting that no load is applied to the door, automatically switches the movement mode,
The door control device according to claim 3, wherein the door speed command generation unit generates the door speed command that causes the moving speed of the door to be lower than a normal speed.

The control result of the door is a door speed of the door detected as a movement amount of the door by the movement amount detection unit,
The door control device may be configured such that a difference between the door speed detected by the movement amount detection unit and the door speed command is equal to or greater than a third threshold value, and the door overload monitoring unit detects that the door is overloaded. If it is, it has a door speed command generating unit for generating a door speed command that stops the door,
The door control device according to claim 1, wherein the motor current control calculation unit outputs a control value of the motor current calculated based on the torque command and the door speed command to the door drive device.

According to the input control value, a door drive device that supplies a motor current to a door motor that opens and closes the door of the car and drives the door,
A movement amount detection unit that detects a movement amount of the door,
A door control device that controls the operation of the door drive device,
