RELAY CONTROL SYSTEM : System Description

DESCRIPTION

IPDM E/R activates the internal control circuit to perform the relay ON-OFF control according to the input signals from various sensors and the request signals received from control units via CAN communication.

CAUTION: IPDM E/R integrated relays cannot be removed.

POWER CONSUMPTION CONTROL SYSTEM : System Description

DESCRIPTION

Outline

  • IPDM E/R incorporates a power consumption control function that reduces the power consumption according to the vehicle status.
  • IPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN communication.

Normal mode (wake-up)

  • CAN communication is normally performed with other control units.
  • Individual unit control by IPDM E/R is normally performed.

Low power consumption mode (sleep)

  • Low power consumption control is active.
  • CAN transmission is stopped.

Sleep Mode Activation

  • IPDM E/R judges that the sleep-ready conditions are fulfilled when the ignition switch is OFF and none of the conditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communication.
  • Outputting signals to actuators
  • Switches or relays operating
  • Output requests are being received from control units via CAN communication.
  • IPDM E/R stops CAN communication and enters the low power consumption mode when it receives a sleep wake up signal (sleep) from BCM and the sleep-ready conditions are fulfilled.

Wake-up Operation

  • IPDM E/R changes from the low power consumption mode to the normal mode when it receives a sleep wake-up signal (wake up) from BCM or any of the following conditions is fulfilled. In addition, it transmits a sleep-ready signal (not-ready) to BCM via CAN communication to report the CAN communication start.
  • Ignition switch ON
  • An output request is received from a control unit via CAN communication.
