Description

Vehicle steering alarm system for slope parking

The present invention relates to a vehicle steering decision system for parking on a slope, and more particularly, to prevent the vehicle from being pushed on a slope due to problems such as poor driving when the vehicle is parked on the slope, and problems such as failure of the shift lever and the parking brake. The present invention relates to a vehicle steering warning system for safe parking by detecting a steering device to prevent and rotating a transmission and a wheel of a vehicle.

In general, when a vehicle is parked on a flat ground or on a slope, braking is performed through a braking device so that the wheel cannot move when the vehicle is stopped by using a parking brake such as a hand brake or a side brake in a parking (P) state of the gear.

However, in general, when a driver is parked, the vehicle's wheels are aligned in a straight line, and as the parking is performed, the slope of the ramp is severe, or the vehicle is pushed due to the inexperience or aging of the vehicle brake.

In order to solve this problem, an accident that occurs when a vehicle descends along a slope is prevented by installing trees on a vehicle wheel or rotating the wheel at a predetermined angle.

However, since it is cumbersome to always install the old trees and always keep them in the vehicle, many uses are not made.

In addition, although the operation to rotate the wheel of the vehicle must be performed, most of the drivers are not aware of the usual driving habits or dangers.

As a prior art for solving this problem, a “automatic steering system for a vehicle for safety parking on a slope and its method” has been proposed.

The prior art is to provide an automatic steering system and method for a vehicle that provides safe parking on a slope by automatically steering a vehicle when parking on a slope, and includes a sensor unit for detecting the slope of a vehicle being parked, and the sensor unit A warning generator configured to output at least one of a warning light and a warning sound by sensing that a vehicle is parked on a slope by inputting a signal detected at, and a steering setting unit that sets the steering direction of the wheel according to the parking position of the vehicle being parked; It is configured to include a control unit that controls the MDPS ECU and the hydraulic control unit inside the vehicle to rotate the wheel of the vehicle in the set steering direction.

Through this, in the prior art, when the vehicle is parked, a warning is generated by detecting the slope, and by controlling the MDPS ECU and the hydraulic control unit inside the vehicle, the wheel of the vehicle can be rotated in a set steering direction.

However, in the prior art, as the rotation of the wheels is automatically controlled with a warning sound in a state that the driver does not accurately recognize, there is a problem that the driver does not accurately recognize the rotation radius of the wheel when the vehicle departs, resulting in a risk of an accident.

In addition, there is a problem in that stable parking cannot be achieved because the wheels of the vehicle are arbitrarily changed due to the inclination angle that occurs when parking is carried out by moving through a separate device of the vehicle at a parking facility such as a parking lot or a parking tower.

As shown in Figs. 1 to 6, the present invention relates to a vehicle steering warning system for parking on a slope, and more particularly, to prevent the vehicle from being pushed due to inexperienced driving or a parking brake problem when the vehicle is parked on a slope. It relates to a steering warning system for a vehicle for parking on a slope capable of safe parking by detecting a steering device so as to be able to rotate a wheel at a predetermined angle.

To this end, the present invention is composed of an inclination angle measuring unit 10, an operation detecting unit 20, a steering angle detecting unit 30 and a control unit 40 so that the driver can check the rotational state of the vehicle wheel according to the state parked on the slope. do.

In this state, the driver can recognize it so that the wheel can rotate according to the slope of the road.

For this, each configuration is made as follows.

The inclination angle measuring unit 10 is installed in the vehicle to measure the inclination of the incline.

Accordingly, the inclination angle measurement unit 10 may be installed at any one position or a plurality of positions among the steering devices to determine the rotation angle of the wheel.

In this example, the first pulley member 31, the second pulley member 32, the first pulley member 31, the second pulley member 32, and the first pulley member 31, the first pulley member 32, so that the rotation angle can be determined according to the operation of the handle shaft corresponding to the steering mechanism among the steering devices as shown in FIG. It consists of a connecting member 33 and a first measuring member 34.

The first pulley member 31 is installed on the rotation shaft 120 of the handle shaft 110 of the vehicle 100.

The second pulley member 32 is rotatably installed in the vehicle 100 by being spaced apart from the first pulley member 31 by a predetermined distance.

In addition, the first measuring member 34 may measure the rotation angle of the wheel through the rotation direction and the number of rotations of the handle shaft 110 according to the direction moved by the first sensing member 33a.

Therefore, the first sensing member (33a) is formed by a protrusion that is coupled to the connection member (33) at regular intervals and protrudes outward, and the first measuring member (34) is a long limit switch sensing by contact of the protrusion. It is preferably composed of.

Here, the first measuring member 34 is preferably positioned above and below the second pulley member 32 so as to individually measure the left and right rotation directions of the handle shaft.

Through this, it is possible to measure the rotation angle of the wheel by the first measuring member 34 through the rotation angle of the handle shaft 110 such as 1 rotation and 2 rotations and the number of rotations.

In addition, the inclination angle measuring unit 10 includes a tension adjusting means 35 for adjusting the tension of the connecting member 33.

As another example, as shown in FIG. 3, the second sensing member 36 and the second measuring member 37 are used to determine the rotation angle of the steering gear 130 corresponding to the steering gear mechanism among the steering devices. Done.

The second sensing member 36 is connected to the rotation shaft 120 of the handle shaft 110 to transmit a rotational force to the wheel at a constant interval at any one portion of the steering gear 130 that moves in the left/right direction. Installed.

The second measuring member 37 is installed in the vehicle so as to be adjacent to the steering gear 130 to measure the second sensing member 36.

Therefore, the second sensing member 36 is installed at a point moving in the left/right direction among the steering gear 130, and the second measuring member 37 moves left/right along the steering gear 130. By measuring the second sensing member 36, the rotation angle of the wheel may be sensed through the moving distance.

That is, it is preferable to be installed on a tie rod that moves left/right by the manipulation of the handle shaft 110.

Here, after the second sensing member 36 has a magnetic member such as a permanent magnet installed, the second measuring member 37 is measured by installing a magnet sensing switch capable of sensing the magnetism of the second sensing member. can do.

Therefore, it can be changed into various configurations so that it can be measured by magnetism in a state exposed to the outside or introduced into the inside.

Through this, it is possible to measure the rotation angle of the wheel according to the movement of the steering gear 130.

In addition, the first sensing member (33a), the first measuring member (34), the second sensing member (36) and the second measuring member (37) measure a rotation angle through contact or measure magnetism. It is made variously so that the rotation angle can be measured through the non-contact type used, but it can be changed according to the measurement configuration.

That is, as a limit switch is disposed on the first sensing member 33a and a protrusion is formed on the first measuring member 34, its role can be changed according to the position.

Through this, the inclination angle measuring unit 10 is installed in any one or a plurality of steering devices for rotating the wheel when the driver's steering wheel shaft 110 is manipulated through a contact or non-contact method to measure the rotation angle of the wheel. I can.

Next, the operation detection unit 20 includes a first detection means 21, a second detection means 22, and a third detection means so that the driving, stopping, and stopping status of the vehicle can be determined by the driver's manipulation. 23).

The first detection means 21 detects an operating state of the engine according to the start of the vehicle.

Accordingly, the driver can determine the starting state of the vehicle through the on/off state of the engine such as stopping the engine by turning off the engine operation and starting by starting the vehicle.

The second detection means 22 detects a shifting state of the vehicle gear.

That is, the second detection means 22 measures the parking, reverse, neutral, and driving states of the vehicle's gear through the driver's manipulation.

In general, auto gears are commonly used here, but in the case of manual operation, the driving stage, reverse and neutral state of the gear are measured.

The third sensing means 23 detects the operating state of the parking brake of the vehicle.

Accordingly, the third sensing means 23 measures the on/off state of the parking brake, which is a hand brake or a side brake.

As described above, the operation detection unit 20 includes the first detection means 21, the second detection means 22, and the third detection means 23 when the vehicle is driven, parked, and stopped. And the gear status can be checked.

Next, the control unit 40 determines the state of being parked on the slope through the information measured by the inclination angle measurement unit 10, the operation detection unit 20, and the steering angle detection unit 30, and gives the driver the direction of the wheel. It consists of a collection unit 41, a determination unit 42, an operation unit 43, an execution unit 44, and a display unit 45 so as to be alerted.

The collection unit 41 transmits the inclination angle of the road measured or sensed by the inclination angle measurement unit 10, the operation detection unit 20, and the steering angle detection unit 30, the vehicle operation state, and the steering angle information of the vehicle. Receive.

The determination unit 42 determines the rotational state of the vehicle wheel according to the inclination angle of the road while the vehicle is stopped using the information collected by the collection unit 41.

Here, the determination unit 42 determines the rotation angle of the vehicle wheel according to the angle change of the slope and the parking direction according to the downhill and uphill.

Through this, it is possible to control the direction of the wheel according to the uphill parking and the downhill parking of the vehicle 100.

The operation unit 43 sets one or more so that a warning sound and a vehicle engine are not operated in a stopped state according to the driver's setting according to the information determined by the determination unit 42.

The operation unit 43 is disposed at a position where the driver can operate while riding in the driver's seat, and the warning method when parking on an incline can be conveniently changed through a button or a lever.

When the execution unit 44 controls the engine start of the vehicle stopped on the slope according to the set value set by the operation unit 43, the warning sound and the vehicle engine are not stopped according to the determination of the determination unit 42. Run the operation.

In addition, the execution unit 44 is provided with a configuration such as an alarm that generates a warning sound, and is configured to guide the user of the rotation state of the wheel through voice guidance along with the warning sound.

Accordingly, it is possible to select a warning sound, a guide sound, or the like according to the user's setting, or control to occur simultaneously.

The display unit 45 displays the steering angle detected by the collection unit 41.

The display unit 45 is disposed in a position adjacent to the instrument panel so that the driver can easily check it, and displays the rotation direction of the vehicle wheel, the rotation angle, and the number of rotations of the steering wheel shaft so that the driver can easily check it.

Therefore, the control unit 40 operates the steering wheel axis according to the inclination angle parking state and parking direction of the vehicle through the information transmitted from the inclination angle measurement unit 10, the operation detection unit 20, and the steering angle detection unit 30. The driver is alerted so that the wheel can be rotated, or the vehicle is controlled so that it cannot be turned off.

In addition, since the angle of the rotated wheel can be checked when boarding, a stable start is possible.

In addition, it is possible to prevent the vehicle from being pushed by controlling the rotation angle of the steering wheel shaft according to the inclination angle of the ramp on which the vehicle is parked.

Through this, the controller may rotate the wheel when the driver parks on the slope and get off the vehicle through the vehicle information, and can check the rotation state of the wheel when boarding for driving.

And it is controlled by the control unit 40, further includes a movement preventing means 50 for suppressing the rotation or movement of the vehicle wheel by operating through an engine stop of the vehicle or a user's manipulation.

The movement preventing means 50 is composed of the operation member 51 and the fixing member 52.

The operation member 51 is respectively installed at the front and rear of the vehicle front wheel and is controlled by the control unit 40.

The fixing member 52 is installed to be vertically moved or rotated by the operation member 51 and is in close contact with the wheel.

Therefore, the operation member 51 is in close contact with the wheel of the vehicle 100 through a vertical movement or rotational configuration of the fixing member 52 to suppress rotation and rotation.

To this end, the operating member 51 operates the operating member 51 through structures such as a motor, a hydraulic cylinder, and a gear.

At this time, the fixing member 52 is fixed by the operation member 51 to support the wheel, thereby preventing the vehicle from being pushed on the slope.

In addition, the operation member 51 may be selected to be operated in an off state after the vehicle is stopped or operated by a driver's manipulation.

Next, the operating state of the present invention according to FIG. 7 will be described.

The vehicle 100 stops in a direction uphill and downhill on a slope.

Here, the inclination angle measurement unit 10 measures the uphill or downhill state and the inclination angle of the vehicle 100.

At this time, when the vehicle 100 stops on an uphill,

The inclination angle measurement unit 10 determines the uphill state of the vehicle 100 and measures the inclination angle.

Thereafter, before the engine start of the vehicle is turned off through the operation detection unit 20, the parking state is determined through the neutral state of the vehicle gear and the operation state of the parking brake.

Here, when the information determined by the control unit 40 is rotated according to the inclination angle while the vehicle's wheel is uphill during the runner brake operation, the vehicle is turned off and parking is possible.

In addition, through the information determined by the controller 40, when the vehicle wheels are not rotated, the engine is not turned off or the driver can recognize the current state through an alarm sound.

In addition, the control unit 40 is interlocked with the vehicle, and is configured to operate a turn indicator according to the direction in which the wheel of the vehicle is rotated, so that when the engine is started, it can be easily checked whether the steering wheel is rotated in the right or left direction.

That is, the inclination angle and the inclination angle of the road at which the vehicle is stopped are measured through the inclination angle measuring unit 10.

In addition, the operation detection unit 20 detects the neutral state of the gear or the driving state through the second detection means 22 when the vehicle engine is turned on through the first detection means 21, and The on state of the jura brake is determined by the 3 sensing means 23.

In such a state in which the parking state is not achieved, it is preferable that the engine start is not turned off or an alarm sound is generated.

In addition, the information measured and sensed by the tilt angle measurement unit 10 and the operation detection unit 20 is transmitted to the control unit 40.

The information transmitted in this way is collected by the collection unit 41 of the control unit 40 and the determination unit 42 determines the parking state.

That is, the determination unit 42 determines whether or not the wheel is rotated in the uphill state of the vehicle, and the information so that the rotation angle of the vehicle wheel is at least a certain angle according to the inclination angle.

In addition, the operation unit 43 is set to operate in one or more of an alarm and start on/off through a driver's manipulation.

Thereafter, when the driver turns off the engine start of the vehicle 100, the warning or engine is not turned off so that the driver can recognize it according to information set in the determination unit 42 and the operation unit 43.

Accordingly, the driver rotates the wheel by manipulating the steering wheel of the vehicle when the vehicle 100 is not turned off or the alarm sounds.

Through this, when the vehicle 100 is uphill, the shift lever is parked, and when the side lever is pulled, the wheel of the vehicle moves to the left in accordance with the direction of travel of the vehicle, and when the vehicle is downhill, the wheel of the vehicle is adjusted to the direction of travel of the vehicle. After rotating to the right, if the rotation is made within the range measured by the inclination angle measuring unit 10, the alarm sound may be turned off or the vehicle may be turned off.

At this time, when the steering wheel shaft 110 of the vehicle 100 is manipulated, the rotation of the rotation shaft 120 or the steering gear 130 connected to the steering wheel shaft 110 is sensed to determine the rotation of the vehicle wheel.

Here, it is preferable to measure the rotation angle of the vehicle wheel by determining the number of rotations of the handle shaft 110 according to the stopped inclination angle of the vehicle 100.

Also, if you stop on the downhill of the vehicle,

The inclination angle measurement unit 10 determines the vehicle's stopping state downhill and measures the inclination angle.

After that, the controller 40 controls an alarm and start on/off when the vehicle is parked through the same operation as the uphill stop.

However, when the vehicle 100 is stopped on the downhill, the vehicle wheel is turned off in a state in which the vehicle wheel rotates in the left direction.

In addition, the control unit 40 determines the rotation angle of the vehicle wheel according to the information set in the determination unit.

That is, as information to the determination unit 42, it is possible to set and change one rotation of the handle shaft when 2 to 10°, 2 rotations of the handle shaft when 11 to 20°, and 3 rotations of the handle shaft when 21° or more.

Through this, the set value can be easily changed according to the weight, type, etc. of the vehicle 100 to prevent accidents that occur when the vehicle is pushed during parking or the vehicle is not stopped through stable parking.

In addition, when parking is performed after rotating the vehicle wheel on the slope, the movement preventing means 50 is operated by the control unit 40.

When parking of the vehicle is completed by the control unit 40, the movement preventing means 50 operates the operation member 51 so that the fixing member 52 comes into close contact with the vehicle wheel.

Through this, it is possible to prevent the vehicle wheel from rotating or rotating arbitrarily, thereby preventing the wheel from rotating due to a strong impact generated by an accident, etc., thereby preventing a secondary accident.
