Question
Justify the suitability and weakness of using independent microcontroller for each
subsystem.

Transcribed Image Text:You are part of a team assigned to design a new smart electric vehicle (EV). There are many
subsystems in the vehicle that needs to be designed:
i) Automatic braking system
ii) Automatic parking system
iii) Auto-lock security system
iv) Battery management system
v) Mobile phone integration system
Each of the subsystems will be controlled by an independent microcontroller. Your
supervisor has assigned you to develop Battery management system.
The EV is equipped battery management system to warn the driver if battery is low. The
battery charge can be read by your microcontroller either through
Digital I/0 (high signal = high charge), or
serial communication (data received is current charge percentage)
Your microcontroller can display the current charge of the battery to the driver using a set
of LED. Your proposed design should include sampling strategy for battery charge
measurement and enabling/disabling car if battery is too low. Additional function such as
warning lights and sound can also be incorporated.
Other features can be incorporated based on your creativity.
Based on the assigned subsystem, complete the following tasks. You should attempt to
include the following microcontroller functions in your design to get full marks:
• 1/0
• Timer / Counter
Interrupt
Serial communication
