Extensive testing and validation activities are carried out as part of the Production part approval process to gain the confidence of the hardware and software.

The development of most ECUs is carried out by Tier 1 suppliers based on specifications provided by the OEM.Īs part of the development cycle, manufacturers perform detailed FMEAs and other failure analyses to catch failure modes that can lead to unsafe conditions or driver annoyance. The design is generally iterative and improvements are made to both the hardware and software. It is rare that a module is developed fully from scratch.

Recently the trend is to dedicate a significant amount of time and effort to develop safe modules by following standards like ISO 26262. Automotive ECU's are being developed following the V-model.

The development of an ECU involves both hardware and software required to perform the functions expected from that particular module.
Metadata for ECU and Software Identification, Version Management, Checksums. Powertrain control module (PCM): Sometimes the functions of the Engine Control Unit and transmission control module (TCM) are combined into a single unit called the Powertrain Control Module. Electric Power Steering Control Unit (PSCU) - Generally this will be integrated into the EPS power pack. Engine control unit (ECU) - not to be confused with electronic control unit, the generic term for all these devices. The engine controller may have several different names, such as "DME", "Enhanced Powertrain", "PGM-FI" and many others. Other Controllers All other controller names are decided upon by the individual OEM. Generic Powertrain The Generic Powertrain pertains to a vehicles emission system and is the only regulated controller name. Generic Industry Controller Naming - Is the naming of controllers where the logical thought of the controller's name implies the system the controller is responsible for controlling. Managing the increasing complexity and number of ECUs in a vehicle has become a key challenge for original equipment manufacturers (OEMs). Embedded software in ECUs continues to increase in line count, complexity, and sophistication. Some modern motor vehicles have up to 150 ECUs. Sometimes an assembly incorporates several individual control modules (a PCM often controls both the engine and the transmission). These ECUs together are sometimes referred to collectively as the car's computer though technically they are all separate computers, not a single one. Modern vehicles have many ECUs, and these can include some or all of the following: engine control module (ECM), powertrain control module (PCM), transmission control module (TCM), brake control module (BCM or EBCM), central control module (CCM), central timing module (CTM), general electronic module (GEM), body control module (BCM), and suspension control module (SCM). An electronic control unit ( ECU), also known as an electronic control module ( ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
