Definition
The objective of this seminar report is to study the automobile application of autotronics and find its range of utilization and also to study how it will improve the performance of the vehicle. This report briefly describes a few automobile applications of autotronics mainly in following domains:
Braking system
Steering system
Suspension system
Transmission system
Engine (fuel intake)
Autotronics is the blend of Automobile + Electronics. The advanced development of vehicles in the last few years was based mainly on electrical and electronic componentsand modules. There is no end in sight to this development. All main functional areas are strongly influenced by the field of electronics or even made possible by it: e.g. anti-lock brake systems, low emission and reduced fuel consumption through electronic motor management systems, anti-theft and electronic diagnosis systems.Analysts estimate that more than 80 percent of all automotive innovation now stems from electronics. For long-haul serial communication between various automotive subsystems such as anti-lock brakes, airbag deployment, engine Control, and GPS navigation, the CAN, LIN, and MOST protocols are the most popular serial buses implemented in today’s vehicles.
By definition, automotive Electronic systems are embedded mixed-signal systems because they feature multiple analog sensors and analog motor controls under digital control. For years, traditional oscilloscopes have been the primary tool-of choice among automotive electronic system design engineers.
Need:
To understand the phenomenal growth of the automotive electronics in Asia Pacific, we first need to understand the evolution of this industry on a global front. To improve efficiency of system communication and to reduce cost, all of today’s automotive designs employ a variety of serial bus communication protocols. The I 2C and SPI protocols are most often used for chip-to-chip communication within electronic control units (ECUs). For long-haul serial communication between various automotive subsystems such as anti-lock brakes, airbag deployment, engine Control, and GPS navigation, the CAN, LIN, and MOST protocols are the most popular serial buses implemented in today’s vehicles.
By definition, automotive Electronic systems are embedded mixed-signal systems because they feature multiple analog sensors and analog motor controls under digital control. For years, traditional oscilloscopes have been the primary tool-of choice among automotive electronic system design engineers to measure the quality of both analog and digital signals. But traditional analog and digital oscilloscopes have many limitations, including lack of complex serial triggering and limited input channels of acquisition. However, a new class of measurement tools called mixed signal oscilloscopes.
Braking System:
The demands made on braking systems are increasing steadily. Therefore, the development and introduction of an electronic braking system (EBS) is a logical step. EBS increases traffic safety through reduced stopping distance and improved brake stability. The full diagnosis and surveillance functions as well as the display of brake Lining wear offer an effective fleet logistics. By actuating the brake pedal the driver defines the deceleration request. The EBS ECU transmits this input electronically To all braking system components. The braking system's shorter response timesprovide a more comfortable and finelytunedbraking feeling, independent of thevehicle’s load situation. EBS provides the basis for the integration of further safety systems like e.g. WABCO ESC (Electronic Stability Control). ESC is a system which independently intervenes in critical driving situations and adjusts engine and brake control. Within physical limits, ESC protects vehicles from rollover, skidding, spinning and jack-knifing.
The EBS contains the following renowned functions:
Endurance brake integration
The braking system has an integrated brake management function which always regulates the endurance br
