WL/WS PASE system has the features described below: Remote Control Conversion of the RF from button press(es), Passive entry into requests: • Unlock request: If the RFHUB receives two FOB unlock button presses, from the same FOB, within five seconds of each other, it sends: a driver door unlock request upon reception of the first press, and a all doors unlock request on the second. • Lock request: Sends the lock request upon reception of a lock button press from the FOB. • Power liftgate toggle request: If the RFHUB receives two FOB unlock button presses, from the same FOB, within five seconds of each other, it sends a power liftgate toggle request. • Panic Toggle Request: Sends the panic toggle request upon reception of a lock button press from the FOB. • Remote start request: If the RFHUB receives two FOB unlock button presses, from the same FOB, within five seconds of each other, it sends a lock request and then a remote start ON request. Keyless Ignition The Keyless Go system replaces the conventional key and ignition switch with a momentary button press and a wireless electronic key (FOBIK). When the operator presses the Go-Button the FOBIK is interrogated wirelessly. If the FOBIK is recognized as belonging to the vehicle and in the vehicle interior the system allows the ignition state of the vehicle to be manipulated by the operator between Off, Run, and Start ignition states. The Following figure shows the system architecture: FCA WL/WS PASE System MY 2021 3 March 18, 2020 RKE (Remote Keyless Entry) Remote Keyless Entry (RKE) telegrams are issued by a ID Device. When pressing one of the buttons, the ID Device transforms the state information about the pressed button (lock, unlock, panic...) into Remote Control Blocks (RCB). The RCB is modulated by an RF signal (315MHz or 433MHz) and sent to the PASE ECU. The RCBs are received by an RF receiver on the PASE ECU which demodulates the RF signal. The packets then get transferred to the host processor which decodes the Manchester coded data, verifies the checksum, and checks if the telegram is addressed to the respective vehicle. The authentication function on the host decrypts the telegram data and transfers the button information to a function which transforms the information into lock, unlock, panic... commands which are in turn transferred to the body control module over CAN. KeyFOB The WL/WS Keyfob is a hand device that sends RF commands to the vehicle provided by the user at the time he wants, such as lock or unlock the vehicle, the remote start, etc. The device responses can be given in two operating frequencies: • WXFOB1 433.92 MHz • WXFOB2 315 MHz At the same time, the KeyFOB it can receive signals of low frequency (125 kHz) to discern its location around the vehicle. Responding to unlock doors or open the trunk sensing the proximity of the user with KeyFOB. Functions The WL/WS Keyfob is part of the WL/WS PASE system and has the following functions: • Transmit RKE commands requested by the User • Receive and decode LF messages from the vehicle for PASE and Polling • Provide to the vehicle RF response to PASE commands and Polling requests • Provide Transponder functionality • Measure its battery level and report it to the vehicle • Provide visual feedback to the User when RKE commands are sent WL/WS Keyfob is a TOKEN-based design. The NXP NCF29A1 TOKEN is a single-chip solution including a Microcontroller, an UHF Transmitter and a Transponder, all in the same package, this feature available in the NXP NCF29A1 TOKEN is enable. FCA WL/WS PASE System MY 2021 4 March 18, 2020 Block Diagram WL/WS Keyfob follows the design shown in the picture below. The HW architecture is based on NXP recommendations to guarantee the best performance of the chipset and consists of the following stages: • UHF Components • 3D LF Front-end • Buttons • LED Driver • Motion Sensor (feature not included in WL/WS) • TOKEN IC (Microcontroller + UHF Transmitter) • Power Supply FCA WL/WS PASE System MY 2021 5 March 18, 2020 Variants The variants of the device are differentiated by the distribution of buttons as well as the frequency of RF tran…
