Abstract

Disclosed are a method and a system for achieving booting of automotive electronics in an electronic control unit of an automobile in terms of early availability of vehicle communication. The method comprises implementing an Open Systems and their interfaces for Electronics in motor vehicles (OSEK) based Controller Area Network (CAN) stack in each of booting phases of the ECU, wherein the CAN stack is stored in a memory mapped region of the ECU. The method comprises creating a data structure storing information pertaining to at least runtime information, state information, message buffers, anddiagnostic session state, wherein the data structure is stored in the memory mapped region. The information stored in the data structure is used for executing one or more instructions of the OSEK based CAN stack for booting the automotive electronics in the ECU, wherein the one or more instructions are executed across each of the booting phases of the ECU.

Description

technical field [0001] The present invention generally relates to automobiles, and in particular, but is not limited to, a method and system for enabling automobile electronics in an electronic control unit (ECU) of an automobile. Background technique [0002] Automotive electronics are the electricity generation systems used in automobiles. The first electronic component of a car is used to control the engine functions of the car and is called an Electronic Control Unit (ECU). As automotive electronic controls are used in more and more automotive applications, the number of ECUs used in automobiles has also increased. Some of the applications for ECUs used in automobiles include transmission control systems, chassis control systems, active safety systems, driver assistance systems, infotainment systems, and passenger comfort systems. In fact, many car buyers today are more concerned with the embedded automotive electronics in a car than with the actual functionality of th...
