Description
The device relates to the automotive industry, i.e. a device for keyless entry, and may be used for disengaging/engaging a vehicle alarm, opening/closing a vehicle door.
There is a known design of an outside door handle for a vehicle, the outside door handle including: a power door lock device positioned within a door of a vehicle and including a lock cylinder; a door handle comprising a fixed grip and a cover, wherein the cover is designed in such a way that it covers at least partially the grip and the lock cylinder and releases at least the lock cylinder in case of an emergency unlocking of the door; and an emergency unlocking device with a traction mechanism, which is designed to activate the emergency opening mechanism and to provide emergency unlocking of the vehicle door, characterized in that the cover is made in the form of a front panel of the handle, which is mounted rotatable relative to the grip and fixed to the grip in the closed position and which is detached from the grip and rotatable relative to the grip in the emergency release position, whereby the front panel of the handle is designed in such a way that by means of a traction action on the front panel of the handle the traction mechanism is actuated for mechanically actuating the emergency unlocking mechanism of the vehicle door, wherein the emergency unlocking device comprises a deflection mechanism, which is connected to the traction mechanism and made and positioned in such a way that it actuates the traction mechanism when the front panel of the handle is pushed [ russian patent No. 2710798, ipce 05B77/10, 14 th year 2020 ].
The disadvantage is that the vehicle is unlocked using a button or touch-sensitive field on the inside of the handle, which increases the risk of failure of the whole system due to mechanical failure of the button.
A motor vehicle door handle with a sensor is known, which interacts with the safety system of the vehicle.

A disadvantage of such designs is that the keyless entry system presented above forms part of the safety system of the vehicle, which is not installed at the manufacturer of all major automobile brands. The entire safety system is fully functional only when it is fully connected to the vehicle, and any integration into a standard safety system using third party control units and components makes the safety system as a whole somewhat fragile.
Another disadvantage of this system is that it cannot be implemented on a software level into a Mercedes-Benz class G vehicle. The vehicle will not receive signals from the third party control unit and thus the entire safety system as a whole will not function on the vehicle.
A KEYLESS GO smart system (see KeylessGo and KEYLESSENTRY |sea-borne smart vehicle entry system) comprising an antenna range amplifier, on the rear windshield, in the trunk, in the left and right rear doors, in the center console, in the electronic transmitter keys, in the antennas in the four door handles, their lock and control units, a system control unit, an electronic ignition switch, on-board electronics at the rear, and trunk lid/tail gate locks and internal data buses.
The disadvantage of this system is that the vehicle control unit cannot be programmed using standard methods and procedures to achieve full operation of the system.
The aim is to be able to implement the functions of unlocking and locking the vehicle by touching a specific area of the door handle, as well as to disengage and engage the vehicle alarm system (standard safety system) on a merseis-pentz class G vehicle.
The technical result is an extension of the tool library for mersad-courz class G vehicles, i.e. keyless vehicle entry systems with built-in sensors for engaging and disengaging alarms and security enforcement systems.
Mersad-courser class G vehicles have very complex protection systems and safety algorithms and can only interact with similar control units and sensors used in other mersad-courser class G vehicles. To achieve this goal and technical result, automobile door handles with built-in sensors are used to engage and disengage vehicle alarms and a safety enforcement system comprising installed software that interacts with the vehicle door handle by the internal unit of the system and with the installed standard program by means of KYELESS GO control unit (standard keyless entry system of the vehicle) to ensure operation of the entire safety system for a merseis-gallon class G vehicle.
Software is loaded into the electronic ignition switch control unit and KYELESS GO control unit via the adapter and diagnostic connector of the vehicle to ensure their communication with the door handle through the door handle antenna and their unit by distributing signals between the electronic ignition switch control unit and KYELESS GO control unit.
This technical result is achieved by creating a cavity in the handle body to accommodate the volume sensor inside the cavity. In addition, additional channels are made in the handle body for routing wires from the volume sensor inside the door cavity. The cavity is closed with a cover. The volume sensor is disposed in the cavity.
The handle includes a door handle body, a door handle body cover, a sensor built into the door handle body, a control unit, and an antenna.
The safety system includes an antenna amplifier, engine start and stop buttons, a key with a transmitter, a door handle with a control unit, a door lock, an internal data bus, an antenna installed in the vehicle, and a Keyless GO system control unit and an electronic ignition switch control unit. The electronic ignition switch control unit is a central interface and a vehicle access authorization system.
The Keyless GO system control unit is designed to interact with the vehicle handle and to engage and disengage the vehicle alarm, and it also performs the functions of unlocking and locking the vehicle by touching a specific area of the door handle using sensors built into the vehicle door handle.
Fig. 1 shows a general view of the handle in a disassembled state.
Fig. 2 shows a cross-section of the handle.
Fig. 3 shows the cover of the handle body.
Fig. 4 shows a volume sensor placed in a cavity of a door handle.
Fig. 5 shows a diagram of a security system.
Fig. 6 shows a diagram of the placement of antennas on a vehicle and the placement of trunk antennas for the left and right rear doors, center consoles, trunk lids.
The security system includes an a10 antenna amplifier, an a11 antenna on the rear windshield, an a17 antenna in the trunk, an a18 antenna for the left rear door, an a19 antenna for the right rear door, an a20 antenna for the center console, an a21 antenna for the trunk lid, an a22 engine start and stop button, an a 16-with-emitter key, an a15/1 left front door handle, an a15/2 right front door handle, an a15/3 left rear door handle, an a15/4 right rear door handle, an a15/5 trunk lid handle, an A2 left front door control unit, an A4 right front door control unit, an A8 left rear door control, an a12 right rear door control unit, an a14 Keyless GO system control unit, an A1 electronic ignition switch control unit, an A6 rear vehicle electronic device (SAM) control unit, an A3 left front door lock, an A5 right front door lock, an A9 left rear door lock, an a13 right rear door lock, an A7 trunk lid/tail door lock, and an internal data bus (CAN B). The central interface control unit is part of an A1 electronic ignition switch control unit.
The central interface and the vehicle access authorization system are an A1 electronic ignition switch control unit. The a14 Keyless GO system (standard Keyless entry system of a vehicle) control unit is modified by means of hardware and software, and new software is installed in the A1 electronic ignition switch control unit.
The software allows the a14 Keyless GO system (standard system) control unit and the A1 electronic ignition switch control unit to interact with the vehicle door handle through their antennas and control units. Thus, a complete interaction of all elements of the system as a single whole is ensured.
After the software is installed, a total reset is performed and all vehicle systems are ready to operate with the system. At the same time, initial software settings are made in the a14 KEYLESS GO control unit, indicating the number of installed handles with internal sensors and radio signal receiving parameters. After all system settings have been completed, the keyless entry system is fully operational.
The system comprises the following sub-functions:
-engine start;
-the engine is stopped;
-a functional process of determining the positioning of a16 key with a transmitter.
A14 KEYLESS GO the control unit initiates an authorization request for a16 key with a transmitter under the following conditions:
-when the last door is closed;
-when the vehicle starts to move (v > 0 km/h) when the door or trunk lid is not closed.
A14 KEYLESS GO the control unit sends a coded request to the a16 key with the transmitter via the a20 antenna in the center console and the a17 antenna in the luggage. A16 keys with transmitters decode these requests and send appropriately encoded responses. A14 KEYLESS GO the control unit receives a response from the a16 transmitter-bearing key via the a18 antenna and a10 antenna amplifier in the left back door, verifies its accuracy, and sends a signal to the A1 electronic ignition switch control unit via the internal data bus. If the analysis is affirmative, the A1 electronic ignition switch control unit authorizes the A16 key with the transmitter. If the vehicle is stopped and the door remains closed, the positioning process is not repeated.
Engine start is performed as follows.
When the a22 engine start/stop button is pressed, a request for engine start is sent. The A1 electronic ignition switch control unit registers the request, and sends a status message "engine start/stop button has been pressed" to the A1 electronic ignition switch control unit via the internal data bus. The A1 electronic ignition switch control unit analyzes this state and transmits activation and positioning signals via all antennas to the a16 key with a transmitter. The a16 transmitter-bearing key sends the engine start authorization code and its location to the A1 control unit via the antenna a17 and a10 antenna amplifier in the luggage case. The A1 electronic ignition switch control unit transmits the data to the A1 electronic ignition switch control unit via the internal data bus. A1 electronic ignition switch control unit checks the engine start authorization code. If it is determined to be valid, the A1 electronic ignition switch control unit sends a signal to allow the engine to start.
The engine is stopped as follows.
When the a22 engine start/stop button is pressed while the engine is running, a request to stop the engine is sent. The A1 electronic ignition switch control unit registers the depression of the a22 engine start/stop button, and sends a status message "engine start/stop button has been depressed" to the A1 electronic ignition switch control unit via the internal data bus. The A1 electronic ignition switch control unit analyzes it and sends a "stop engine" request via the internal data bus.
The a21 antenna on the trunk lid allows the location of the a16 key next to the trunk lid to be determined and the convenient unlocking/locking function of the lid can be used with the handle on the trunk lid we make (rather than the original handle).
Additional conditions for locking/unlocking:
the key a16 with the transmitter is positioned outside the vehicle (maximum distance from the control element is 1 m).
The lock/unlock function allows the vehicle to be unlocked and locked using the central lock system.
The following elements are used to unlock and lock the vehicle:
a15/1KEYLESS-GO external left front door handle
A15/2KEYLESS-GO external right front door handle
A15/3KEYLESS-GO external left rear door handle
A15/4KEYLESS-GO external right rear door handle
The functions of locking and unlocking the vehicle are implemented according to the following algorithm:
Conventional unlocking occurs if any of the A15/1, A15/2, A15/3, A15/4 door handles is touched from the inside of the handle.
Unlocking options:
touching any door handle or pulling any door handle.
To lock the vehicle, the outside of one of the A15/1, A15/2, A15/3, A15/4 outside handles should be touched.
Examples of full unlocking on the left front door:
The capacitive sensor (recessed touch surface) of the door handle detects a touch to the a15/1 left front door handle. A14 KEYLESS GO the control unit reads the capacitive sensor signal and sends an activation signal to the a16 key with a transmitter via the a18 antenna in the left rear door.
The a16 key with transmitter transmits an authorized access code and its location to the a14 KEYLESS GO control unit via the a11 rear windshield antenna and a10 antenna amplifier. A14 KEYLESS GO the control unit sends this data to the A1 electronic ignition switch control unit via an internal data bus. The A1 electronic ignition switch control unit verifies the entry authorization code of the A16 key with the transmitter. If it is determined to be valid, the A1 electronic ignition switch control unit sends a "unlock door" request to the following control unit via the internal data bus:
-A6 a rear in-vehicle electronics (SAM) control unit;
-A2 left front door control unit;
-A4 right front door control unit;
-A8 left rear door control unit;
-a12 right back door control unit.
The A2 left front door control unit unlocks the A3 left front door lock through a corresponding motor of the central control lock system. And the A4 right front car control unit unlocks the A5 right front door lock through a corresponding motor of the central control lock system.
The A8 left rear door control unit unlocks the A9 left rear door lock using the motor for the left rear door of the center control lock system.
A12 right rear door control unit unlocks the doors using the motor for the right rear door of the center lock system.
