Description

Vehicle control method {VEHICLE CONTROL METHOD}

The present invention relates to technology that enables selective use of some functions of a vehicle.

Recently, even if you do not have a smart key for the vehicle, there are vehicles that allow you to open the vehicle door, start the vehicle, and drive the vehicle by holding a pre-registered smartphone, just as if you had a smart key.

Alternatively, there are vehicles that allow you to open the vehicle doors and start the engine using a pre-registered fingerprint.

However, in the case of a vehicle that can be driven with a smartphone, it is impossible to use the vehicle without carrying a smartphone.

In addition, in the case of vehicles that can be driven using fingerprints, if the vehicle is a car belonging to a car sharing company, the user's biometric information may remain in the car sharing company, making personal information protection vulnerable. , there is a risk that the fingerprint recognition rate may decrease due to rain or contaminants.

The matters described as the background technology of the above invention are only for the purpose of improving the understanding of the background of the present invention, and should not be taken as recognition that they correspond to prior art already known to those skilled in the art. It will be.

It may include more than one processor.

Referring to Figure 1, an embodiment of the vehicle control method of the present invention includes the step of monitoring whether a wake-up input from the operation switch is detected (S20); After detecting a wake-up input of the operation switch, displaying a status in which a designated code can be input (S30); A step of determining whether a predetermined reference time has elapsed after the designation code is input (S40); After the reference time has elapsed, checking whether the input designation code corresponds to a preset designation code (S50); When a preset designation code is input, it includes a step (S60) of performing and allowing the vehicle function in the mode corresponding to the designation code.

In other words, the present invention allows the vehicle function in the mode corresponding to the designation code to be performed and permitted when the designation code is input after the wake-up input is input by the operation switch mounted on the vehicle, thereby keeping the vehicle within a predetermined range. This is so that it can be used within.

In this embodiment, the step (S20) of monitoring the wake-up input of the operation switch first performs the step (S10) of detecting whether the user requesting use has legitimate hardware, and if the user does not possess legitimate hardware, , be carried out.

Here, the legitimate hardware refers to a device that allows the use of all functions of the vehicle, such as a smart key or a pre-registered smartphone.

In addition, the person requesting use is not only the owner of the vehicle, but also a delivery driver, valet parking driver, car wash worker, etc. who is temporarily permitted to operate or use the vehicle by the owner or a person with legitimate rights to the vehicle. It is a concept that includes the same third party.

In other words, this embodiment allows the vehicle to be operated as in the past when possessing legitimate hardware such as a smart key, and when not possessing legitimate hardware such as the above, the designation input through the operation switch is used. It allows users to use the vehicle's functions within a predetermined range according to the code.

The wake-up input of the operation switch includes at least one on-off combination, and the final state consists of a state change of the operation switch in the off state.

That is, for example, if the operation switch is turned on when pressed and turned off when released, the fact that the person requesting use presses the operation switch once and then releases it can be judged as the wake-up input.

At this time, since the final state of the operation switch is off, when the designation code is input later, the designation code can be recognized as being input from the state in which the operation switch is turned on again.

When the wake-up input from the operation switch is detected as described above, the vehicle flashes the vehicle's lamps, such as the side mirror turn signal lamp, etc., to notify the user that wake-up has been completed so that the designated code can be input. Do it (S30).

After checking the wake-up completion signal as above, the user requesting use inputs the designated code into the operation switch.

Here, the designation code consists of a long and long combination of the on and off states of the operation switch.

That is, by inputting the on-state duration and the off-state duration of the operation switch in a certain order, respectively long or short, such as pressing the operation switch in the on state for a long time and then turning it off, or pressing the operation switch in the on state for a short time and then turning it off. This allows you to enter a specific designated code.

After a series of operation switches for inputting the designation code are operated and the above reference time has elapsed (S40), it is determined that the input of the designation code is complete, and the received designation code is transferred to a controller such as a BCM (Body Control Module). deliver it to

Here, the reference time is to check whether the input of the designation code has been completed through a series of operation switches, and may be set within the range of several seconds, or may be set to 2 seconds as illustrated in FIG. 1. .

Of course, the designation code is set in advance in the vehicle's controller, such as the BCM, so that if the designation code input through the operation switch as described above matches any one of the pre-stored ones, the designation code corresponding to the input designation code is set in advance in the vehicle controller such as the BCM. Allows and performs the vehicle functions of the mode.

If the mode corresponding to the above designation code is the delivery receiving mode, the function of unlocking the trunk door of the vehicle is performed, so that the trunk door of the vehicle is unlocked even if the courier does not have a legitimate right, such as the owner of the vehicle. Open and allow delivery of parcels.

For example, as shown in Figure 2, when the delivery driver inputs the designation code corresponding to the delivery receiving mode with the outside door handle switch, the BCM determines this and requests the CCU (Central Control Unit) to activate the trunk latch actuator. This is to run it in an unlocked state.

Here, the outside door handle switch is used as the operation switch.

In other words, the operation switch can be installed as a separate switch outside the vehicle in a location accessible to anyone, but as described above, the outside door handle switch can be used as the operation switch of the present invention.

Meanwhile, if the mode corresponding to the designation code is valet parking or car wash mode, the door of the vehicle is unlocked and the personal information lock function of the information terminal mounted on the vehicle is performed.

For example, as shown in Figure 3, when a valet parking engineer or car wash worker inputs a designation code corresponding to valet parking or car wash mode using the outside door handle switch, the BCM determines this and locks the vehicle's door with a door latch actuator. By unlocking, valet parking technicians or car wash workers can board the vehicle, while performing the personal information locking function of information terminals such as AVN (Audio Video Navigation), personal information such as the vehicle owner stored in the vehicle is protected. This is to prevent leakage through the information terminal.

Additionally, when the mode corresponding to the designation code is valet parking or car wash mode, the BCM can limit the allowable vehicle speed of the vehicle to a predetermined reference vehicle speed or less through a TCU (Transmission Control Unit).

In other words, for example, the allowable vehicle speed is limited to 30 km/h to prevent theft or improper use of the vehicle.

Therefore, in accordance with the above-mentioned purpose, the reference vehicle speed may be appropriately set to a level that only allows the vehicle to park or move at a car wash.

If the mode corresponding to the above designated code is the parking assistance mode, change the vehicle's gear shift from P to N and release the parking brake.

This mode is designed to prepare for cases where parking is insufficient, such as double parking, and the vehicle must be pushed into N gear. If information on the designated code for the parking assistance mode is displayed on the outside of the vehicle, The user who needs to push and move the vehicle can enter this designation code to push and move the vehicle.

For example, as shown in Figure 4, when a user who needs to push and move the vehicle inputs the designation code displayed on the vehicle through the outside door handle switch, the BCM determines this and causes the TCU to change the gear shift from P to N. Then, activate the PRA (Parking Release Actuator) to release the parking brake, so that the vehicle can be moved by pushing it from the outside by hand.

It would be desirable to maintain the state changed to N gear and the parking brake released status only for a predetermined time limit, and after the time limit elapses, return the shift gear to P gear and activate the parking brake. will be.

Therefore, the time limit may be set appropriately, for example, 10 seconds, taking into account the time required to push and move the vehicle in the parking lot.

If the mode corresponding to the designation code is the memory seat mode, the vehicle door is unlocked and the seat is adjusted to the seat position and posture matching the designation code.

For example, as shown in Figure 5, when the requester inputs the designation code corresponding to the memory seat mode through the outside door handle switch, the BCM determines this and unlocks the door with the door latch actuator, allowing the requester to board the vehicle. While doing this, the IMS actuator is driven through the IMS (Integrated Memory Seat) controller to adjust the position and posture of the seat to a preset state.

Here, there may be more than one designation code corresponding to the memory sheet mode.

In other words, each family member has an individual designation code corresponding to the memory seat mode, and the seat position and posture corresponding to each designation code are individually preset, so each member can use the seat position and posture optimized for him/her. You will be able to use your vehicle.

Therefore, this case can be used in cases where the owner and the corresponding legitimate rights holder can operate the vehicle without having a separate smart key, etc.

Accordingly, when the mode corresponding to the designation code is the memory seat mode, the vehicle's controllers may be operated to allow use of all functions of the vehicle.

Meanwhile, as described above, the operation switch is an outside door handle switch of a vehicle, and an on-off operation input of the outside door handle switch can be judged as an input of the operation switch.

In addition, it is preferable that the designation code is entered in advance through an information terminal such as AVN mounted on the vehicle.

However, it may also be possible to set the designation code in advance by operating the operation switch.

That is, in the step of monitoring the wake-up input of the operation switch (S20), when a predetermined setting input distinct from the wake-up input is detected, from then on, by a long and short combination of the on and off states of the operation switch, The purpose is to set the designated code.

Here, the setting input may be made, for example, in an on state that is pressed longer than the long on state of the operation switch forming the designation code.

In other words, if the operation switch is pressed in the on state for a much longer time than the signal constituting the designation code, the mode for setting the designation code is entered, and the operation switch input from then on is a new designation code that is previously controlled by a controller such as BCM. It is to be stored in the back.

For reference, it would be desirable to use the designation code set using the operation switch when setting a mode that allows only simple functions such as unlocking the vehicle door.

Although the present invention has been shown and described in relation to specific embodiments, it is known in the art that various improvements and changes can be made to the present invention without departing from the technical spirit of the invention as provided by the following claims. This will be self-evident to those with ordinary knowledge.
