ECM
  • For purposes including improving the feeling when shifting speeds and preventing drops in engine speed, control signals are exchanged between the ECM and TCM, and real-time cooperative control is performed according to the vehicle driving conditions. (Engine and CVT integrated control)
    • Engine and CVT integrated control signal
      NOTE: General term for the communication (torque-down permission, torque-down request, etc.) exchanged between the ECM and TCM.
  • The TCM receives the following signal via CAN communications from the ECM for judging the vehicle driving conditions.
    • Engine speed signal
    • Accelerator pedal position signal
    • Closed throttle position signal
BCM The TCM receives the following signal via CAN communications from the BCM for judging the vehicle driving conditions.
  • Stop lamp switch signal
ABS actuator and electric unit (control unit) The TCM receives the following signal via CAN communications from the ABS actuator and electric unit (control unit) for judging the vehicle driving conditions.
  • Vehicle speed signal (ABS)
  • ABS operation signal
Combination meter The TCM receives the following signal via CAN communications from the combination meter for judging the driving request from the driver.
  • Manual mode signal
  • Non-manual mode signal
  • Manual mode shift up signal
  • Manual mode shift down signal
IPDM E/R The TCM receives the following signal via CAN communications from the ABS actuator and electric unit (control unit) for judging the vehicle driving conditions.
  • A/C compressor feedback signal
MDU(1) The TCM receives the following signals from MDU via CAN communication to switch driving mode of the Integrated Control System.
  • NORMAL mode signal
  • ECO mode signal
  • SPORT mode signal
(1) With Integrated Control System
