Description of FIG.

FIG. 3 corresponds to FIG. 2 and shows another control example of the present invention. In the embodiment of FIG. 3, as the predetermined operation state of the door outer handle, four types of X1 to X4 are set as described later. In addition, a plurality of electrical components are set to be operated according to the operating state of the door outer handle. More specifically, as electrical components, there are power windows, slide sunroofs, lights for interior lighting, all lights such as small lamps other than lights for interior lighting, and foldable door mirrors.

In the case of FIG. 3, the predetermined operating states of the electrical components corresponding to the door outer handle are roughly classified into two types. In the first case, a plurality of electrical components are respectively operated in a predetermined manner so as to be in a preferable state when the occupant is separated from the vehicle in one type (common) operating state of the door outer handle (operating state X1 in the embodiment). This is the case when the state is set. The second case is a case where, of the electric components, only a predetermined electric component (which may be a plurality of electric components or a single electric component) is selectively brought into a predetermined operating state.

Explanation of the operation state of the door outer handle

A description will be given of a case where four types of X1 to X4 in FIG. 3 are set for a predetermined operation state of the door outer handle. As described above, the door outer handle returns to the original predetermined position when the pulling external force is released. Therefore, if the door outer handle is intermittently pulled a predetermined number of times, it is turned on by the pulling operation of the door outer handle.
As for the operating state of the door switch S1, the ON / OFF operation is repeated a number of times corresponding to the number of times the outer door handle is pulled. In the embodiment of FIG. 3, the operation states X1 to X4 are set as the difference in the number of times of the intermittent pulling operation of the door outer handle.

Specifically, the operation state X1 is set so that the door outer handle is intermittently pulled four times (the door switch S1 is repeatedly turned on and off four times). The operation state X2 is set so that the door outer handle is intermittently pulled five times (the door switch S1 is repeatedly turned on and off five times). The operation state X3 is set so that the door outer handle is intermittently pulled six times (the door switch S1 is repeatedly turned on and off six times). In the operation state X4, the door outer handle is set to 7
It is set so as to be pulled intermittently (the door switch S1 is turned on and off seven times repeatedly). In the case of the embodiment of FIG. 2, any one of the operation states X1 to X4 described above is selected.

The count of the intermittent pulling operation of the door outer handle described above is set to be within a predetermined time. That is, for example, 3 as the predetermined time
The intermittent pulling operation is counted only for a second (3 seconds from the first pulling operation detection), and after 3 seconds as the predetermined time, the operation is performed according to the counted number of intermittent pulling operations. It is finally determined whether the state is X1, X2, X3, or X4.

The operation state can be set in various ways other than the above. For example, it can be set as a combination of the number of times of pulling operations of the door outer handle. More specifically, the first time is set to 3 seconds and the second time is set to 3 seconds as the predetermined time, and the number of pulling operations during the first 3 seconds is α1, and the second time is 3 seconds. When the number of pulling operations at is α2 (α1 and α2 are 1 or more and 9 or less, respectively), the combination of “α1 · α2” means a two-digit number.
Digits can be used to distinguish between operating states. It should be noted that, for example, a beep sound is generated between the first predetermined time period and the second predetermined time period, and it is the timing when the operator shifts from the first time to the second time. You can also let us know. Of course,
It is possible to set the operation state with three or more digits by developing the above description.

When setting a predetermined operation state of the door outer handle, it is preferable to make it as simple as possible so as not to be bothered by an occupant to operate it, and the door outer handle that is performed when the door is actually opened. It is preferable to set such that the operation state of is excluded. For example, if you try to open the door without noticing that the door is locked, the pulling operation of the door outer handle may be performed intermittently about twice. It is preferable to set a predetermined operation state.

Supplementary explanation

In this case, when the preferred operating state is obtained when the vehicle is separated from the vehicle, all of them may be turned off in order to suppress battery consumption. Further, as exemplified by Q29 in FIG. 3, in order to obtain a preferable state when an occupant is in the vehicle compartment, in addition to lighting the interior lighting lamp, control of the air conditioner (usually when the engine is the drive source) There are many cases, so it becomes a simple control of ventilation etc.), and the ON operation (heating) of the seat-warmer, etc.

(2) In the embodiment, the electric equipment is controlled by the door outer handle on the assumption that the ignition switch is OFF. However, when the ignition switch is ON, the electric equipment by the door outer handle is controlled. You may make it control.

(3) It is only necessary to bring a plurality of electrical components into a predetermined operating state by one predetermined operating state of the door outer handle, and each of the electrical components can be independently operated. The predetermined operation states may be associated with each other, or a combination of both may be used as shown in FIG.

(4) Components such as the control unit U and the relay RS that are used to control electrical components by the door outer handle are restricted in their installation positions due to the door structure, such as the switches (sensors) S1 to S3. Except for the above, it is preferable to make the unit as one unit as much as possible in view of inexpensive construction, improvement in assembling to a vehicle, and size reduction. Of course, if possible, one unit including the switches S1 to S3 can be made. In this case, one unit can be used to detect the operating state and lock of the door outer handle by the switches S1 to S3. It is installed on the door so that the position is suitable for. (5) The correspondence relationship between the predetermined operation state of the door outer handle and the predetermined operation state of the electrical components may be set to a fixed value at the time of factory shipment of the vehicle, but the purchaser of the vehicle may arbitrarily set the above correspondence.

It (6) The timer count start in Q4 of FIG. 2 may be started when the determination in Q2 is YES, that is, from the detection of the locked state of the door (Q23 of FIG. 3).
Correspondence). In this case, by setting a predetermined time (for example, 1 to 2 minutes) from the door lock, the occupant is separated from the vehicle while ensuring that the time required to bring the electrical components to the predetermined operating state is more than sufficient. After that, it is preferable for preventing mischief in which the electrical component is brought into a predetermined operating state against the will of the occupant. (7) The timer may start counting in Q23 in FIG. 3 from the detection of a predetermined operation state of the door outer handle, as in the timing in Q4 in FIG. 2 (Q in FIG. 3).
(Starting counting from the time point when the determination of 24, Q26, Q28 is YES), in this case, the predetermined time is set as the minimum time required to complete the operation of the electrical component, and it is particularly preferable for preventing overload. Become. Of course, two types of timers can be easily provided, and a first timer that starts counting from the detection of a predetermined operation state and a second timer that starts counting from door lock detection in FIG. 2 can be provided (the second timer can count). The predetermined time to be used is longer than the predetermined time to be counted by the first timer).
