What Causes BMW Chassis Stabilization Malfunction Warning To Appear
Overview of Vehicle electronics and Introduction to ECUs
1. Impact of Innovation in automotive electronics in Vehicles…
Now a days advancement in vehicles are achieved by Electronic Control Unites.
Fuel efficiency and emission control is mostly full fill by advance ECUs functioning in vehicles. These ECUs are helping
Human beings To reduce pollutants coming out of Internal Combustion Engine.
Passenger safety and vehicle stabilization systems is part of ECUs.
Comfort and Convenience has improved at great extend.
Up to 90% innovation in vehicles are realised by electronic device integrated in automobiles.
2. • Number of
microcontrollers in CAR
Consumers increasingly expect the latest and greatest in electronics and safety when purchasing a car, regardless of
type. Whether it’s an instrument cluster with a graphics rich, fully reconfigurable display or a lane departure warning
system, a tremendous amount of processing power and electronic communication is required. The current approach
to adding these features to vehicle’s electric/electronic (E/E) architectures is generally “ad-hoc”—i.e., simply adding
a new ECU every time a new vehicle feature requires processing power. This has resulted in vehicles with as many as
100 ECUs and more than 100 million lines of code in ultra-luxury cars.
4. Vehicle Architecture
The architecture of a system represents
its “construction plan”.
• Architecture should include the functional and
non-functional requirements
• To fulfil this different views of system Architecture is
required.
• Hardware architecture
• Software architecture
• Network architecture
• Cost and resource consumption
• social requirements aspects such as safety, availability and legal
conformity
7. • Vehicle Software Architecture
The Electronic control unit (ECU) receives the electrical signals from the sensors,
evaluates them, and then calculates the triggering signals for the actuators. • The
“software”, is stored in a special memory and implemented by a microcontroller. •
The control unit and its components are referred to as hardware.
