PASSIVE ENTRY - Description

Description

The Passive Entry and Easy-Go systems are used to manage car protection, passenger compartment access and engine start-up.

The passenger compartment access and engine start-up system described allows customers to enter their cars and start their engines without using a key but simply by carrying a CID.

When the driver approaches the (locked, immobilized) vehicle and pulls the handle when they have a CID (e.g. in their pocket), the system automatically recognizes the CID and unlocks the doors and switches the alarm off.

Once the customer is sitting in the driver's seat and presses a button in the dashboard the system allows the engine to be started up

When customers reach their destination, they press the button again and the engine is turned off. See E7065 ELECTRIC STEERING LOCK.

When customers have left the car, they can lock the doors and activate the alarm by pressing a button on the exterior handle. If the system has previously been set, it automatically locks the car after the customer has walked away (with the CID in their pocket).

The entire car use cycle is therefore carried out without needing a key to open/close the car (remote control function) or to turn the engine on/off (ignition key function)

In addition to the control unit, connected to the CAN network, the system also consists of a special device known as a CID (Customer Identification Device) which replaces the normal key with remote control.

Like a key the CID contains a transponder with CODE system codes, and a battery for the Alarm/Central Locking remote control transmitter.

There are 3 buttons on the CID for locking, unlocking and opening the boot.

The system also includes a mechanical key for emergencies if the Easy-Go system does not work and to activate/deactivate the passenger airbag module.

This key cannot be used to start the car.

The car is not fitted with an ignition. Instead a button on the facia is used to turn the car on and off and start it up.

As there is no longer a mechanical key, the steering lock function is achieved electrically via a unit integrated in the electronic control unit connected to the CAN.

The door/boot handles are also slightly different; they contain 2 switches and are able to carry out 2 types of manoeuvre from a stable position:

  • PULL HANDLE: the handle is pulled out to open the door controlling the opening of the door
  • PRESS HANDLE: the handle can be pressed inwards controlling the locking of the locks (NOTE the boot also behaves like a door)

The search for the CID for opening the doors takes place via 5 exterior aerials, that for the starting go-ahead takes place via 3 interior aerials.

There is also an RF aerial which receives the door opening/closing signal in the same way as a conventional remote control.

The system may not be able to detect the CID at the time the start button is pressed because it is not working or because the CID battery is flat. In that case, the CID is set to garage position, i.e. to the old immobiliser aerial on the central console.

With key-on, the aerial is activated in the same way as with the old code system and the magnetic field generated activates the CID transponder which enables the start-up system if it is detected.
