Designing an Ignition Control for Automotive Applications
This article will discuss the design of an ignition control used in Electrical Power Steering system of automobiles by using a microcontroller plus ASIC or microcontroller plus programmable logic SoC. Such a system receives the ignition input from the user and vehicle inputs through a CAN transceiver and drives the three-phase brushless automotive motor. Using available processing headroom, the MCU can also perform battery monitoring, temperature sensing, direct drive LED or LCD display with temperature, battery status, speed value, and distance and error/warning messages. This article discusses design techniques as well as design challenges for Ignition control in Electrical Power Steering system used in automotive application.
