Abstract
A door opening and closing apparatus has a motor, a door latch and a power generation mechanism. When the voltage of the battery is below a level needed to drive the electric actuator, a predetermined manipulation of the power generation mechanism generates the power needed to drive the motor. Therefore, when the voltage of a battery that supplies electric power to the electric actuator is below a level needed to drive the electric actuator, the door opens.
Claims13
A door opening and closing apparatus for a vehicle that includes an electric actuator for electrically operating a door latch, wherein the electric actuator is supplied with power driven by a voltage from a battery, the apparatus comprising:
- a portable device held by a user, wherein the portable device wirelessly transmits an ID signal, which includes an ID code;
- a power generation mechanism, wherein, when the voltage of the battery is below a level needed to drive the electric actuator, a predetermined manipulation of the power generation mechanism generates the power needed to drive the electric actuator;
- and
- a communication control unit, which is driven by power of the battery, wherein the communication control unit compares the ID code transmitted from the portable device with an ID code stored in the communication control unit in advance, wherein the communication control unit permits the electric actuator to be driven only when the condition is met that the ID codes coincide with each other, and wherein, when the voltage of the battery is below a level needed to drive the electric actuator, the communication control unit permits the electric actuator to be driven based on the condition that the ID codes coincide with each other only when the condition is met that power required for driving the electric actuator is obtained by the power generation mechanism.
A door opening and closing apparatus for a vehicle that includes an electric actuator for electrically operating a door latch, wherein the electric actuator is supplied with power driven by a voltage from a battery, the apparatus comprising:
- a portable device held by a user, wherein the portable device wirelessly transmits an ID signal, which includes an ID code;
- a manipulation member, which is manipulated to selectively open and close a door;
- a power generation mechanism, wherein, when the voltage of the battery is below a level needed to drive the electric actuator, a manipulation of the manipulation member generates the power needed to drive the electric actuator;
- a detection device for detecting whether the manipulation member has been manipulated;
- and
- a communication control unit, which is driven by power of the battery, wherein the communication control unit compares the ID code transmitted from the portable device with an ID code stored in the communication control unit in advance, wherein the communication control unit permits the electric actuator to be driven only when the conditions are met that the ID codes coincide with each other and that the manipulation member has been manipulated based on a detection signal from the detection device, and wherein, when the voltage of the battery is below a level needed to drive the electric actuator, the communication control unit permits the electric actuator to be driven based on the conditions that the ID codes coincide with each other and that the manipulation member has been manipulated only when the condition is met that power required for driving the electric actuator is obtained by the power generation mechanism.
