When the door open / close command determination process (L2) and the door open / close determination process (L3) are sequentially performed, it is determined that the door is opened by the door open / close operation unit (step 103) and the current door is closed (step 107). In step S4, a precondition determination process L4 is performed to determine whether the on / off state of the ignition key (step 110) and the speed sensor 92 are signaled (step 111).

At this time, when the door opening and closing command determination process (L2) and the door opening and closing determination process (L3) in order to proceed sequentially determined by the door closing command from the remote controller 88 and the door opening and closing operation unit (step 104) and the current door Is determined to be open (step 108), the door 첵 solenoid valves 71a to 71d corresponding to the buttons 3a to 3d are operated (step 112) to close the door without any condition (step 113). When the closing process (L5) is executed, but the start-up state is received and the signal is received from the speed sensor 92, it is recognized as driving and ignores the open signal and maintains the current state (step 102). L4) will be performed.

On the other hand, when the essential condition determination process (L4) is performed, that is, a condition that is the door opening command from the door opening and closing operation unit 3, the current door is closed, the start is on, there is no signal from the speed sensor 92 When all are satisfied, as shown in FIG. 13B, the vehicle is recognized as being in a stopped state, and then a satisfying condition determination process (L6) is performed to determine whether any one or more of the plurality of satisfying conditions are satisfied.

Herein, if the satisfying condition determining process L6 satisfies all of the necessary condition determining process L4, it is determined whether or not it is related to driving afterwards, that is, a state in which a signal is received from the parking brake detecting unit 96. The driver determines that the parking brake is operating (step 114), or receives a signal from the pedal brake detection unit 94, i.e., the driver brakes the pedal brake (step 115), or the transmission A signal is received from the parking detection sensor 95a and the neutral detection sensor 95b of the detection unit 95, that is, the driver determines that the transmission is in the parking (P) and neutral (N) states (step) 116) or if the driver detects that no object detection signal is received from the object detection sensor 93 (step 117). It is short.

Therefore, when all of the necessary condition determination process (L4) is satisfied and at least one condition in the fulfillment condition determination process (L6) is satisfied, the door lock solenoid valves 72a to 72d are turned on for about 2 seconds to open the door. By controlling, the door lock cylinders 16a to 16d are driven to release the door lock 18 for 2 seconds (step 118), and then the corresponding door solenoid valves 71a to 71d are turned on. The door 첵 cylinders 10a to 10d are driven to open the doors 5a to 5d (step 119).

At this time, the MPU 91 counts the time (step 120) from the time when the door solenoid valves 71a to 71d are driven, and drives the door solenoid valves 71a to 71d. After determining whether the object detection signal from the object detection sensor 93 is present even in the process of continuously opening the door (step 121), it is determined whether the counted time of 4 seconds has elapsed in the state where the object is not continuously detected (step 122) to perform the door opening process (L7).

The reason for counting for 4 seconds is that the door is completely opened after about 4 seconds from the time when the door is opened by the doors cylinders (10a to 10d). Differences may occur and the present invention does not limit time.

After the door opening process (L7), if the counted time in the state that the object is not detected 4 seconds elapsed, the door solenoid valve (71a ~ 71d) is switched to the neutral state (step 123) and at the same time By operating the brake solenoid valves 73a to 73d of the brake devices 40a to 40d, the door stop process L8 is performed to keep the doors 5a to 5d open (step 125).

If it is determined that the door open / close signal is received from the remote controller 88 or the door opening / closing operation unit 3 in the state in which the doors 5a to 5d are opened through the door stopping process L8 (step 126), it is shown in FIG. 13A. The door opening and closing command determination process L2 is performed.

At this time, the limit switches 97a and 97b contacted when the door handles 9 and 9a of the doors 5a to 5d are operated while the door open / close signal of step 126 is not received. (9c) When it is determined that the brake release signal is received from the touch switch 97c provided on one side (step 127), the brake solenoid valves 73a to 73d may be turned off to manually close the doors 5a to 5d. After performing the door release process L9 for maintaining the manual mode (step 128), the door open / close signal receiving process L1 shown in FIG. 13A is performed.

On the other hand, when the start is turned off, that is, the start is turned off (step 110) in the prerequisite determination process (L4) shown in Figure 13a is executed from the door opening process (L7) shown in Figure 13b, the door opening process When an object is detected at L7, the door stopping process L8 shown in FIG. 13C is performed.

4 seconds has elapsed in the door opening process (L7), the door (5a ~ 5d) is completely open (step 122), or the object within the range that the doors (5a ~ 5d) open in the door opening process (L7) In the case of sensing (steps 117, 121) and switching the door solenoid valves 71a to 71d to the neutral state in the MPU 91, the doors 5a to 5d are quickly changed by the characteristics of the door cylinders 10a to 10d. When the pin cylinders 43a to 43d are driven in the MPU 91 as shown in (b) of FIG. 8, the rod 44 is momentarily raised, and as the rod 44 rises, Therefore, as the brake pad 45 comes into close contact with the interlocking rod 42, a frictional force is formed to act as a brake, thereby immediately stopping the doors 5a to 5d, and thus, the doors 5a to 5d. The opening will be interrupted to prevent accidents.

In addition, the MPU 91 lights up the light emitting diodes LED1 to LED8 corresponding to each door open / close button 3a to 3d of the door open / close operation unit 3 so as to visually check the open / close state of each door. In the case of applying the present invention when manufacturing a passenger car, the same working relationship can be obtained by replacing the MPU 91 with an electronic control unit (ECU).

As described above, according to the present invention, the condition that the door is opened automatically by the door cylinder should be an opening command from the remote controller or the door opening / closing operation part, and at the same time, the vehicle stops without the speed signal from the speed sensor of the vehicle. If the parking brake is operating under the necessary conditions, the transmission lever is parked (P) or neutral (N), the pedal brake is operating or the object is not detected. By opening the door to be satisfied, there is an effect that can prevent in advance a safety accident that may be caused by a driver's mistake and contribute to improving the precision of the door opening and closing device for a passenger car.

In addition, the present invention is to install a brake device to quickly stop the opening of the door at a predetermined position of the panel, when the object is detected within the range that the door is opened when the door is opened by the door cylinder put the solenoid valve in a neutral state Simultaneously with the switching, the brake device is driven to quickly stop the opening of the door, thereby increasing the stability.

According to the present invention, when the door is completely opened by the door 첵 cylinder driving, the door 동시에 cylinder is made neutral and at the same time, the brake device is driven to keep the door open. In this state, the door is closed from the door open / close button or the remote controller. When a signal is received or a signal is received from the brake release switch that is contacted during internal / external handle operation, the brake is automatically released to allow the door to be closed automatically and manually so that the door can be properly responded to according to the user's situation. There is an effect that can contribute to the improvement of the precision of the switchgear.
