A CAN system has been adopted which can send and receive multiple signals over a single communication path from related modules.
A CAN system has been adopted which can send and receive multiple signals over a single communication path from related modules.
HS-CAN
MS-CAN
The CAN system consists of CAN system-related modules built into the CPU and wiring harnesses connecting related modules.
Terminator resistors are built into the PCM and instrument cluster which form the HS-CAN between the PCM and instrument cluster.
Terminator resistors are built into the rear body control module (RBCM) and instrument cluster which form the MS-CAN between the rear body control module (RBCM) and instrument cluster.
The instrument cluster is connected to the HS-CAN and MS-CAN which communicate with each other via the instrument cluster.
The front body control module (FBCM) is located at the front of the vehicle, the start stop unit is located in the dashboard, the rear body control module (RBCM) is located at the rear, and lighting parts, wiper parts, each type of switch, and door lock parts in each location are each connected to three CMs, creating a three-system communication network.
The front body control module (FBCM) and start stop unit are connected to the HS-CAN and the rear body control module (RBCM) is connected to the MS-CAN which communicate with each other via the instrument cluster.
For example, when the switch connected to the start stop unit is turned on, the start stop unit sends an operation request signal to the front body control module (FBCM) and rear body control module (RBCM), which operate the parts on the front or rear.
By connecting the front body control module (FBCM), start stop unit, and rear body control module (RBCM) via the CAN, the number of wiring harness used compared to the conventional number used has decreased.
Signals transmitted using the CAN system are as follows:
