OVERVIEW

Introducing M36O

OpenECU™ M360

M360 OpenECU is designed to support high current applications with a favorable functional safety ISO 26262 architecture. M360 is designed with two H-bridges capable of 50 A of transient current. These H-bridges can be used to control brushed-DC Motor automotive applications. Applications include Electric Park Brake (EPB) or Electric Parking Brake (EPB) ECU development.

M360 has a dual-microcontroller architecture with asymmetric hardware and software redundancy.

The high-performance MPC5746B microprocessor supported by the powerful 32-bit SPC560P34 secondary microprocessor provides for sophisticated, high-bandwidth rationality checking and system safety monitoring of full-authority vehicle control applications.

Features

  • Powerful dual micro-processor architecture with intermicro serial comms for program flow monitoring and 1x shared external CAN channel from both micros
  • 2x H-bridges for high current outputs (10A continuous, 50A transient for 100ms)
  • Comprehensive fault diagnosis supporting functional safety as well as OBD requirements
  • High level diagnostics fault reporting resident in platform software
  • Platform SW supports light-duty J1979/KWP2000/UDS 14229 and Heavy-duty J1939 service tool interfaces
  • Supported platform software: OpenECU-FS

APPLICATIONS

M360 Applications Include:

Application Description
Electric Parking Brake M360 can be used as Electric Parking Brake (EPB) ECU replacing traditional mechanical parking brakes. The M360 as an EPB can control actuators to provide parking brake function and also dynamic braking as a secondary braking system.
High Current H-Bridge Module With 10A continuous and 50A peak (or transient) current H-Bridges M360 can be used in applications to control motors
