## Abstract

In order to provide a vehicle door controlling apparatus, which even when the vehicle starts to move while doors of the vehicle are in closed operation, performs insertion detection accurately without reducing the sensitivity of insertion detection. In the present invention, speed adjustment is performed by an applied voltage and a vehicle door is driven by a motor by voltage driving. The speed during the movement of the vehicle door is detected by Hall elements, and the door speed during the movement of the vehicle door is obtained from the detected signal. A controller having an insertion detection function controls the door speed to be the predetermined target door speed. In this case, the controller detects stoppage or driving of the vehicle, and when the state of the vehicle is in the driving state while the vehicle door is in closing operation, the voltage applied to the motor is increased compared to the stop state.

## Claims

### Claim 1

A vehicle door controlling apparatus, the apparatus comprising a driving means which drives a door of a vehicle, a speed detecting means which detects the speed of the door of the vehicle, and a controlling means which controls the door of the vehicle to make the speed of the door of the vehicle approach a predetermined target door speed based on an output from the speed detecting means and performs deceleration control of the door of the vehicle just before a whole closed position, wherein the controlling means detects an entrapment of an object caused by an opening and closing operation of the door of the vehicle, and stops driving the door or drives the door toward a whole open position when the entrapment is detected, wherein the apparatus further comprises a driving detecting means which detects a stop state or a driving state of the vehicle, and when the vehicle is in the driving state while the door of the vehicle is controlled in a direction for closing, the apparatus increases a voltage applied to the driving means compared to the stop state of the vehicle.

### Claim 2 (depends on 1)

The vehicle door controlling apparatus according to claim 1, wherein said controlling means memorizes a current door speed and a past door speed, and calculates an estimated door speed which is a door speed after a predetermined amount of time by performing door speed estimation from both the current door speed and the past door speed, and calculates a voltage increase or decrease amount of the voltage applied to the driving means based on a deviation between the estimated door speed and the target door speed, and controls a voltage to be applied to the driving means based on the voltage increase or decrease amount.

### Claim 3 (depends on 1)

The vehicle door controlling apparatus according to claim 1, wherein the driving means comprises a motor.

### Claim 4 (depends on 2)

The vehicle door controlling apparatus according to claim 2, wherein the driving means comprises a motor.
