HD MAP MODULE

FUNCTIONS WITHIN THE SYSTEM

HD map module transmits HD map data to ADAS control unit 2 via Ethernet communication.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

  • HD map module stores HD map data.

  • HD map data cannot be displayed on the screen of navigation system or visually viewed in any other way because HD map data is used to control ProPILOT Assist 2.1.

    NOTE:

    The data for navigation system is stored in the AV control unit.

  • If there is the latest HD map data, it is updated automatically. For updating HD map data, refer toSystem Description.

INDIVIDUAL OPERATION

ProPILOT Assist 2.1: Refer to System Description.

PARTS LOCATION

Refer to Component Parts Location.

POWER NETWORK SEPARATE RELAY

FUNCTIONS WITHIN THE SYSTEM

  • In order to continue the function of ProPILOT Assist 2.1 even in the abnormal condition, the power supply system of ProPILOT Assist 2.1 is divided into two power supply groups such as sub starter & generator side (Group A) and 12 V sub-battery (Li-ion battery) side (Group B).

  • Power network separate relay is installed between two power supply groups.

  • Power network separate relay detects voltage fluctuation of each power supply group during ProPILOT Assist 2.1 operation.

  • When abnormality occurs on one of two power supply groups during ProPILOT Assist 2.1 operation, power network separate relay cuts off the circuit to maintain function by the normal power supply group.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

Power network separate relay cuts off the circuit between sub starter & generator side (group A) and 12 V sub-battery (Li-ion battery) side (group B) according to voltage fluctuation.

INDIVIDUAL OPERATION

System backup function: Refer to System Description.

PARTS LOCATION

Refer to Component Parts Location.

ROOF ANTENNA AND ANTENNA FEEDER

FUNCTIONS WITHIN THE SYSTEM

  • Roof antenna (GNSS antenna) that is communication antenna of HD map module receives radio waves from global navigation satellite.

  • Radio wave that received from global navigation satellite is amplified and transmitted to HD map module as GNSS antenna signal.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

Built-in GNSS antenna is used in HD map module.

INDIVIDUAL OPERATION

GNSS antenna is supplied power from HD map module and receives positioning information from global navigation satellite.

PARTS LOCATION

Refer to Component Parts Location.

ANTENNA FEEDER

STEERING WHEEL TOUCH SENSOR

FUNCTIONS WITHIN THE SYSTEM

The steering wheel touch sensor detects driver's steering wheel holding status and transfer its signal to ADAS control unit 2 via LIN communication.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

The steering wheel touch sensor judges if the steering wheel is held or not.

INDIVIDUAL OPERATION

The steering wheel touch sensor is integrated with the entire steering wheel and utilizes electrostatic capacity change between the electrode of sensor and the hand to judge whether the steering wheel is held or not.

PARTS LOCATION

Refer to Component Parts Location.

ProPILOT Assist Steering Switch

FUNCTIONS WITHIN THE SYSTEM

  • By operating the switch located on the steering wheel, it is easy to operate ON/OFF of ProPILOT Assist 2.1 and set Nissan Ariya vehicle speed/vehicle-to-vehicle distance.

  • The steering switch operation by the driver is input to ECM and transmitted to ADAS control unit 2 via CAN communication.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

  • The steering switch operation by the driver is detected.

INDIVIDUAL OPERATION

  • ProPILOT Assist steering switch consists of a capacitive switch and a combination of resistors.

  • When each switch is pressed, the voltage changes according to the resistance value specified to each switch. ECM reads which switch is operated depending on the voltage.

PARTS LOCATION

Refer to Component Parts Location.

Steering Assist Switch

FUNCTIONS WITHIN THE SYSTEM

Transmits a steering assist switch signal to ADAS control unit 2.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

Steering assist switch allows the ON/OFF of steering assistance function.

INDIVIDUAL OPERATION

Steering assist switch changes the switch operation of driver to the voltage change (ON: 0V / OFF: 12V).

PARTS LOCATION

Refer to Component Parts Location.
