The operation of the vehicle window and the door lock drive control apparatus having the above-described embodiments will be described as follows.

When a driver and a child ride on a different seat 1 of a vehicle equipped with the apparatus according to the present invention and travel while the driver is away from the car to see an urgent task, the weight The output of the comparator COP1 is brought to a low level since a "low" signal is outputted from the sensing means 2 and input to the comparator COP1 of the comparing means 3. [

On the other hand, in the weight sensing means 2 mounted on the child seat 1, a "high" signal is outputted to the comparator COP2 of the comparison means 3 and compared with the reference voltage Vref, Since the voltage output from the weight sensing means sensing the weight of the child is less than the reference voltage Vref, the output of the comparator COP2 is in the low state. Therefore, the output of the NAND gate NAN of the combining means 4 Quot; high "state.

If the output of the NAND gate NAN of the combining means 4 is in a "high" state, the first and second timers of the timing means 5 output a " The door lock motor 8 and the power window motor 9 are operated by the transistors Q1 and Q2 of the first and second switches 6 and 7 to be turned on so that the door is completely locked and the window is raised, 2 timer counts different times and drives power window and door lock with time difference.

Example 2

FIG. 2 is a view showing a vehicle window and a door lock drive control apparatus according to another embodiment of the present invention.

In the figure, the weight sensing means 2 is mounted on a plurality of vehicle seats 1 to detect whether there is a driver or an occupant, and outputs a corresponding voltage. The comparing means 3, (COP2) (COP3) (COP4) for comparing the voltage output from the plurality of weight sensing means 2 with the reference voltage Vref. When the child 1 is present in the seat 1, The reference voltage is set so that the voltage output from the sensing means 2 is less than the reference voltage Vref.

The combining means 4 is constituted by a NAND gate NAN which combines the data outputted from the comparators COP1, COP2 and COP4 of the comparing means 3, And outputs predetermined switching control signals in accordance with the data output from the means 10 and the data output from the startup ON / OFF sensing means 20.
