Hereinafter, with reference to the accompanying drawings, for example an embodiment according to the technical idea of the invention vehicle starting off phenomenon prevention device and the control method configured as described above are as follows.

<Example>

As shown in FIG. 1, the sensor unit 10 detects the number of revolutions of the engine, the current speed of the vehicle, the inclination of the vehicle, the current position of the transmission, and the like to generate a signal for controlling the vehicle, and transmit the signal to the ECU 20. The ECU 20 receives data of various sensors input from the sensor unit 10 and applies a control signal to the engine unit 30 according to the speed of the vehicle, the output of the engine, the state of the vehicle, and the like. In 30, the control signal is applied from the ECU 20 to generate power to adjust the speed of the vehicle, and the alarm unit 400 notifies the driver when the position of the transmission input from the sensor unit 10 is incorrect. The present embodiment is constituted by allowing the gear to fit the vehicle speed.

On the other hand, the vehicle speed sensor 11 of the sensor unit 10 detects the current speed of the vehicle is applied to the ECU 20, the engine RPM sensor 12 detects the current engine speed of the vehicle To the ECU 20, the up and down tilt sensor 13 detects how much the up and down tilt of the car is when the car is on a hill, and transmits it to the ECU 20, and the shift stage detecting switch 14 It detects whether the transmission is located at the current speed and applies it to the ECU 200. When the driver steps on the accelerator, the throttle valve is opened. At this time, the throttle position sensor 15 detects how much the throttle valve is opened and the ECU 20 By transmitting to the present embodiment, the present embodiment is constructed.

Hereinafter, the operation of this embodiment configured as described above with reference to the drawings as follows.

When driving a car using a manual gear, you have to stop the car. When the driver presses the brake with the clutch, the engine power is not transmitted to the wheels and the car stops. At this time, if the driver puts the transmission in neutral, the driver may take off the clutch. However, if the driver does not put the transmission in neutral and the gear is put in, the ignition is turned off.

However, novice drivers and female drivers unfamiliar with manual gears often start the car with their gears in 3rd, 4th, or 5th stages without the transmission in neutral or with the transmission in the 3rd, 4th or 5th gear. In this case, it is only natural that the car is turned off. In addition, drivers who are unfamiliar with manual gears may be mishandled by clutches and accelerators on hillsides, causing the car to be pushed backwards and to be ruined.

Thus, as shown in Figure 1, by attaching the shift stage detection switch 14 to the transmission to detect where the position of the transmission, the vehicle speed sensor 11 to detect the current vehicle speed, the engine The RPM sensor 12 is used to detect the engine speed.

The data detected by the vehicle speed sensor 11, the engine RPM sensor 12, and the shift stage detecting switch 14 is applied to the ECU 20.

The ECU 20 receiving data from the vehicle speed sensor 11, the engine RPM sensor 12, and the shift stage detection switch 14 compares the data applied from the sensor unit 10 with each other. When the speed of the vehicle detected in (11) is 0 km / h, if the position of the transmission is in the 3rd, 4th, or 5th stage, the ECU 20 determines that the current transmission position is not suitable for starting the car. The signal is applied to the alarm device 40 to inform the driver that the alarm device 40 receives the signal, and the alarm device 40 receiving the signal from the ECU 20 sounds an alarm to inform the driver that the position of the transmission is incorrect. .

The driver who knows that the position of the transmission is wrong through the alarm device 40 adjusts the position of the transmission, so that the driving of the engine unit 30 is normally performed, so that the driver can start the vehicle so that the starting of the vehicle is not turned off.

Meanwhile, as shown in FIG. 1, the vertical tilt sensor 13 is attached to the sensor unit 10 to cope with the phenomenon that the starting is turned off on the hill. When the driver presses the accelerator pedal to start the vehicle while the vehicle is stopped on the hill, the throttle position sensor 15 detects how much the throttle valve is opened and transmits it to the ECU 20, and the vehicle speed sensor In (11), the current vehicle speed is detected and transmitted to the ECU 20, the engine RPM sensor 12 detects the number of revolutions of the engine and transmits to the ECU (20). In the ECU 20, which receives data from the vehicle speed sensor 11, the engine RPM sensor 12, and the up and down tilt sensor 13, the vehicle speed input from the vehicle speed sensor 11 and the engine RPM sensor 12 may be used. The speed of the engine unit 30 is rapidly increased until the threshold value of the engine speed required for starting the vehicle is reached by combining the input engine speed and the tilt degree of the vehicle input from the vertical tilt sensor 13, and then The rotation speed of the engine unit 30 is kept constant in that state.

However, since the threshold value of the engine speed required to start the vehicle is different according to the state in which the vehicle is stopped, the tilt of the vehicle is measured using the up and down tilt sensor 13 of the vehicle, and the measured data is stored in the ECU ( 20, the ECU 20 controls the rotation speed of the engine unit 30 according to the current vehicle inclination based on the data applied from the up and down inclination sensor 13.

Hereinafter, referring to FIG. 2, a control method of a device for preventing starting of the vehicle is described with reference to FIG. 2. The first step of comparing and determining whether the current vehicle speed is 0 km / h using the vehicle speed sensor 11 (S1) )Wow; When the speed of the vehicle is 0 km / h as a result of the comparative determination in the first step S1, the ECU 20 detects whether the gears of the vehicle are 3, 4, or 5 gears by using the shift stage detection switch 14. Comparing the second step (S2) and; A third step (S3) of informing the driver through the alarm unit 40 that the starting may be turned off when the gear is 3, 4, or 5 gears as a result of the comparison in the second step (S2); A fourth step (S4) of shifting the gear by the driver who has learned that the state of the gear is in error through the alarm unit (40) in the third step (S3); Shifting the gear and operating the clutch to start the vehicle without starting off (S20); A fifth step of measuring the inclination of the vehicle by the up and down inclination sensor 13 and inputting the inclination measured by the ECU 20 when the gear is not 3, 4, or 5 gears as a result of the comparison in the second step S2 ( S5); A sixth step S6 of determining, by the ECU 20, the inclination degree of the vehicle input from the up and down inclination sensor 13; A seventh step S7 of determining an engine speed threshold according to the slope; An eighth step S8 of increasing an input value of the throttle position sensor 15; A ninth step S9 of increasing the engine speed up to the engine speed threshold according to the inclination degree; A tenth step (S10) of comparing whether the current engine speed and the engine speed threshold value are the same; In the tenth step 10, if the current engine speed and the engine speed threshold are not the same, the current engine speed is increased to the engine speed threshold, and the current engine speed and the engine speed threshold are increased. If the values are the same, the driver shifts the gear and operates the clutch to operate the twentieth step (S20) of starting the vehicle without starting off.

As described above, the present invention prevents the start-up of the vehicle and its control method, in particular, by attaching a shift stage detecting switch to detect the position of the gear when the speed of the vehicle is 0 km / h and inform the driver of the rotation of the engine. By increasing the number to the appropriate turning force to start the car to prevent the car from starting off, the operation of the novice driver or the clutch pedal is effective for the inexperienced female driver can drive freely.
