Abstract

PURPOSE:To improve safety when parking on a sloped road by arranging such that a warning is issued when a vehicle is determined to be sloped either in uphill or downhill condition and further when it is determined that a transmission gear is not either in a low or reverse position. CONSTITUTION:During a drive of a car, if it is determined by a signal of an ignition key detection part 21 that the ignition key is turned off and if it is determined by a signal of a hand brake detection part 23 that the hand brake is applied, it is judged by a signal of a slope sensor 17 if the car is placed on a slope or not by means of a condition determining part 29. And when it is determined to be YES, it is determined if the car is on an uphill or downhill slope. A warning output part 31 is actuated to issue a warning when a low gear detection part 25 determines that a low gear is not selected while the car is on an uphill slope or when a reverse gear detection part 27 determines that a reverse gear is not selected while the car is on a downhill slope.

A change gear detection unit detects whether or not the vehicle is tilted, and a signal from the inclination detection device determines that the vehicle is in an uphill or downhill state. A condition determination unit that determines that the gear is not selected as low gear A7 or reverse gear, and a condition determination unit C1 for determining that the gear is not selected as low gear ψ or back gear. A parking danger warning device is constructed by including an alarm device that generates an alarm.

(Embodiments of the Invention) Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Referring to FIG. 1, an automobile 1 is parked on a slope R, for example.

In addition, the car 1 may be parked on a slope R. A hand brake 5 is attached to a vehicle body 7 and is located beside a seat portion 3 of a driver's seat in an automobile 1. Moreover, a shift lever 9 for shifting the change gear A7 is provided near the handbrake 5.

A change gear (not shown) is attached to the shift lever 9, and the change gears include a low gear, a second gear, a third gear, a top gear\7, and a back gear. Selected through collaborative shifts.

An engine 11 for driving the car 1 is provided in the front part of the car 1, and an ignition key 13 for operating the engine 11 is removably inserted into a part of the interior panel part 15 in front of the driver's seat. It is now possible to do so.

A tilt sensor 17 as a tilt detection device is attached to a part of the lower part of the in-panel section 15.

The tilt sensor 17 may be of any kind, as long as it can detect tilt. Further, a newsletter device 19 is provided in a part of the upper part of the in-panel section 15 to inform that the low gear A or reverse gear is not selected especially when parking on the slope R.

As shown in FIG. 2, the ignition key 13 for operating the engine 11 has an ignition key for detecting whether the engine 11 is turned off when the ignition key 13 is removed from the interior panel. The detection unit 21 is connected.

The handbrake 5 includes a handbrake detection unit 23 for detecting whether the handbrake 5 is applied or not.
is connected.

The shift mill lever 9 has ■ as an engine gear detection part.
A low gear detection section 25 for detecting whether gears -7 to -7 are selected and a back gear detection section 27 for detecting whether rose gear A7 is selected and -C are connected.

These ignition key detection section 21, handbrake detection section 23, low gear detection section 25, and back gear detection section 27 are connected to a condition determination section 29.

The condition determination unit 29 also includes an inclination detection sensor 1 which serves as an inclination detection device and detects whether or not the C automobile 1 is inclined.
7 is connected.

The condition determination section 29 is connected to an alarm output section 31, and the alarm output section 31 is further connected to the newsletter device 19. When the condition determining unit 29 determines that the ignition key 13 is turned off based on the ignition key detecting unit 21h, etc., a signal is sent to the alarm output unit 31, and the alarm output unit 31 further outputs a signal. This is incorporated into the warning device 19, and the driver is informed by a warning display or a warning buzzer.

Furthermore, in the condition determination section 29, the handbrake detection section 23
If it is determined that the handbrake 5 is not applied based on the signal from the controller, the warning device 19 notifies the driver via the warning output unit 31 by displaying the θ information or by a warning buzzer, as described above.

Furthermore, the condition determination unit 29 determines that the vehicle 1 is tilted and stopped in an upright state based on the signal from the tilt sensor 17, and that the vehicle 1 is in a low gear due to the signal from the gear detection unit 25. If it is determined that C is not selected, a signal is sent to the alarm output section 31 in the same manner as described above.

If it is determined by the signal from the inclination sensor 17 that the vehicle 1 is tilted and stopped in a downward state, and if it is determined by the signal from the back gear detection section 27 that the back gear is not selected, the process is performed in the same way as described above. A signal is sent to the alarm output section 31. In this manner, if the low gear or reverse gear is not selected, a signal is sent from the alarm output section 31 to the alarm device 19, and the driver is notified by a warning display or a warning buzzer. The alarm device 19 may be used in combination with a loop lamp, a door switch, etc., if necessary.

Next, the processing operation of the condition determining section 29 in this embodiment will be explained based on the flowchart shown in FIG. Third
In the figure, first, in the 0th stage, it is determined whether the ignition key 13 is turned off based on a signal from the ignition key detection section 21, and if it is not turned off, the process ends.

If the ignition key 13 is turned off, the process advances to stage 0. If it is determined that the handbrake 5 is not applied in the 0th stage, a signal is sent to the alarm output unit 31, and the alarm device 19 displays a warning or a warning buzzer informs the driver that the handbrake 5 is not applied. let them know. If it is determined that the handbrake 5 is pulled in the 0th gear, the vehicle advances to the 0th gear.

At the 0th stage, it is determined whether the vehicle 1 is tilted or not, and if the vehicle 1 is not tilted, it is parked as is. If the car 1 is tilted, the process further advances to the 0th stage and determines whether the car 1 is going up or down a slope, for example. If it is determined that the automobile 1 is in a state where it is going up a slope, the process proceeds to the 0th stage. If the low gear is selected in the 0th gear, there is no problem and the car will be parked. When the low gear is selected, a warning is displayed on the alarm device 19 or a warning buzzer is used to inform the driver that the low gear is not selected.

If it is determined at the 0th stage that the automobile 1 is in a downhill state, the process proceeds to the 0th stage. If reverse gear is selected in 0th gear, there is no problem and the car will be parked. If the back gear is not selected, a signal is sent to the alarm output section 31, and the alarm device 19 displays a warning or uses a warning buzzer to notify the driver that the back gear is not selected.

With the above configuration, when the ignition key 13 is off, when the handbrake 5 is not pulled, when the car 1 is stopped on a slope and the low gear is not selected, and when the car 1 is on a slope In either case, when the driver is stopped in a lowered position and the reverse gear is not selected, an alarm device 19 properly informs the driver with a warning display or a warning buzzer. However, the C1 driver is required to reconfirm the parking position based on the warning display or warning buzzer.

Note that the present invention is not limited to the above-described embodiments, but can be implemented in other embodiments by making appropriate changes.

(Effects of the Invention) As can be understood from the above description of the embodiments, according to the present invention, an inclination is detected when the vehicle is going up or down a slope, and a low gear or a back gear is selected. When the vehicle is not in use, an alarm system can be used to notify the driver of this fact.

Therefore, since the driver is informed of the situation by the warning, he or she almost never forgets to check again and select the forward gear or reverse gear. As a result, accidents are prevented from occurring.

Furthermore, when parking a car on a slope, low gear or reverse gear must be used, making the parking brake system fail-safe and increasing reliability.
