Abstract

The invention provides a vehicle door opening and closing system for making a notice before opening and closing a door by using a motor to enhance the safety. The inventive is a door opening and closing system mounted on a vehicle including a controller generating and sending a first instruction and a second instruction, a motor controlled by the controller so as to open or close the door and an announce mechanism controlled by the controller. The first instruction instructs the motor to drive after a predetermined wait time from the generation of the first instruction; and the second instruction instructs the announce mechanism to announce generation of the first instruction for a predetermined notice time before starting to drive the motor.

Claims

1. A door opening and closing system mounted on a vehicle comprising:

a controller generating and sending a first instruction and a second instruction;

a motor controlled by the controller so as to open or close the door; and

an announce mechanism controlled by the controller;

wherein the first instruction instructs the motor to drive after a predetermined wait time from the generation of the first instruction; and

the second instruction instructs the announce mechanism to announce generation of the first instruction for a predetermined notice time before starting to drive the motor.

2. The door opening and closing system according to claim 1, wherein the wait time includes the notice time and a predetermined recognition time.

3. The door opening and closing system according to claim 2, wherein the controller further generates and sending a third instruction, wherein the third instruction instructs the motor to drive after the recognition time.

4. A door opening and closing system mounted on a vehicle comprising:

a controller generating and sending a first instruction and a second instruction;

a announce mechanism controlled by the controller; and

a door opening and closing device controlled by the controller comprising;

a latch mechanism changing states including at least a full latch state and a half latch state;

a motor driving the switching of the latch mechanism; and

a latch switch detecting the states of the latch mechanism;

wherein the first instruction instructs the motor so that the latch mechanism changes from the half latch state to the full latch state after a predetermined wait time from when the half latch state is detected by the latch switch; and

the second instruction instructs the announce mechanism so as to provide a signal during a predetermined notice time in order to inform the detection of the half latch state.

5. The door opening and closing system according to claim 4 further comprising a plurality of the door opening and closing devices, wherein the plurality of the devices are spontaneously controlled by the controller.

6. The door opening and closing system according to claim 4, wherein the latch switch comprises:

a half latch switch; and

a full latch switch,

wherein the half latch switch changes from an ON state to a OFF state when the latch mechanism changes into the half latch state; and

the full latch switch changes from an OFF state to a ON state when the latch mechanism changes into the full latch state.

7. The door opening and closing system according to claim 4, wherein the controller stops the motor driving if a time between when the half latch switch changes from the ON state to the OFF state and when the full latch switch changes from the OFF state to the ON state during closing operation is longer than a predetermined notice determination time threshold value.

8. The door opening and closing system according to claim 5, wherein the controller drives the motor so as to open the door after the motor stopping.
