Abstract

A control apparatus of an opening and closing body for a vehicle includes a fully closed state detection means detecting a fully closed state of an opening and closing body for the vehicle, an authenticating means authenticating a user of the vehicle, a detection means detecting a command for an opening operation when the authenticating means and the portable unit authenticate each other, a driving means conducting the opening operation when the fully closed state and the command for the open operation are detected, wherein the detection means is a vibration sensor mounted at one of the opening and a butted surface of the opening and closing body for the vehicle, and the vibration sensor detects that an object is pinched between the opening and the opening and closing body for the vehicle at a closing operation.

Claims

1. A control apparatus of an opening and closing body for a vehicle, comprising:

a fully closed state detection means detecting a fully closed state of an opening and closing body for the vehicle in which the opening and closing body for the vehicle is fully closed, the opening and closing body for the vehicle opening and closing an opening formed at a vehicle body;

an authenticating means mounted at the vehicle and authenticating a person as a user of the vehicle by communicating with a portable unit;

a detection means detecting a command for an opening operation of the opening and closing body for the vehicle when the authenticating means and the portable unit authenticate each other; and

a driving means conducting the opening operation of the opening and closing body for the vehicle when the fully closed state of the opening and closing body for the vehicle is detected by the fully closed state detection means and the command for the open operation of the opening and closing body for the vehicle is detected;

wherein

the detection means is a vibration sensor mounted at one of the opening of the vehicle body and a butted surface of the opening and closing body for the vehicle with which the opening is butted when the opening and closing body for the vehicle is in the fully closed state, and the vibration sensor detects that an object is pinched between the opening and the opening and closing body for the vehicle at the time of a closing operation.

2. A control apparatus of an opening and closing body for a vehicle according to claim 1, wherein the detection means distinguishes vibration caused by the object being pinched from vibration caused by the command for the opening operation of the opening and closing body for the vehicle in the opening and closing body for the vehicle or the vehicle body, and distinction is made based on a frequency of a vibration.

3. A control apparatus of an opening and closing body for a vehicle according to claim 2, wherein the distinction of the vibrations is made by the detection means using a band pass filter.

4. A control apparatus of an opening and closing body for a vehicle according to claim 3, wherein one of a high pass filter and a low pass filter is used as the band pass filter for distinguishing the vibrations by the detection means.

5. A control apparatus of an opening and closing body for a vehicle according to claim 4, wherein the distinction of the vibrations is made by the detection means at a frequency range of 100 Hz.

6. A control apparatus of an opening and closing body for a vehicle according to claim 5, wherein the user knocks the opening and closing body for the vehicle and the vibration is caused by knocking sound generated by knocking.

7. A control apparatus of an opening and closing body for a vehicle according to claim 1, wherein the detection means is mounted at the opening and closing body for the vehicle comprising the butted surface with which the opening is butted when the opening and closing body for the vehicle is in the fully closed state.

8. A control apparatus of an opening and closing body for a vehicle according to claim 1, wherein the detection means is mounted at the vehicle body comprising a butted surface with which the butted surface of the opening and closing body for the vehicle is butted when the opening and closing body of the vehicle is in the fully closed state.

9. A control apparatus of an opening and closing body for a vehicle according to claim 1, wherein the opening and closing body for the vehicle is one of a slide door, a swing door, a back door, a trunk lid and a fuel lid.

10. A control apparatus of an opening and closing body for a vehicle according to claim 1, wherein the vibration sensor serving as the detection means is a sheet formed sensor detecting pressure variations.
