Abstract

PURPOSE:To correctly detect the shift lever position using a simple constitution by connecting a neutral sensor SW connected to a starter magnet SW coil via a diode to the plus terminal of a comparator, and also to the plus terminal of a battery and connecting the minus terminal of the comparator to the plus terminal of the battery. CONSTITUTION:Now when a neutral sensor SW3 is in the OFF position, approximately 5V of the plus voltage of a battery is applied across the plus terminal of a comparator 5. When the SW3 is in the ON position, the current of the battery 1 runs from the secondary terminal of a starter magnet SW coil 4 via the SW3 to the earth so that the voltage at the plus terminal of the comparator 5 drops to the proximity of zero. On the other hand, an approximately 5V is applied constantly across the minus terminal of the comparator 5 so that the ON or OFF position of the SW3 may be determined by comparison of the comparator 5 between a variation in voltage at the plus terminal of the comparator 5 with said value. That is, the N or P position of the shift lever in an AT automobile may be detected. A diode 6 is used as a preventing means for reverse current to the comparator 5.

(Prior Art) Conventionally, in automatic transmission vehicles, a neutral sensor SW for detecting whether the shift lever is in the N or P position is directly connected to the starter magnet SW, and this is used to start the engine. If the shift lever is not in the N or P position, the magnet switch of the starter cannot be turned on, and therefore no radio waves will flow to the starter coil, making it impossible to start.

However, since the conventional neutral sensor SW is connected in series with the engine key switch, a separate detection device for the N or 2nd position of the shift lever is required for the starting device, and a new detection device is required. This may require a great deal of effort and expense, so there has been a demand for a detection device that is accurate and easy to install.

(Function) In this device configured in this way, when the neutral sensor SW (3) is currently OFF, no current flows, so the ■ voltage of the battery (1) is approximately 5 V at the ■ terminal of the comparator (5). It takes a while. Neutral sensor SW (3)
is ON, the current from the battery (1) passes through the neutral sensor 5W (3) and the starter magnet SW.
Since the voltage flows from the secondary side of the secondary coil (4) to the ground, the voltage at the ■ terminal of the comparator (5) drops to near O. On the other hand, a constant voltage (approximately 5V) is always applied to the ○ terminal of the comparator (5), so by comparing the voltage fluctuations of the ■ terminal of the comparator (5) with this comparator (5), the neutral It is possible to detect whether the sensor SW (3) is ON or OFF, and in other words, the N or P position of the shift lever in an AT vehicle can be detected by using changes in the voltage applied to the neutral sensor SW (3). This detection signal is input to another device, such as a starter device. In addition, the diode (6
) is for preventing backflow to the comparator (5), and the variable resistor (
9) is for making it possible to adjust the constant voltage applied to the θ terminal of the comparator (5).
