US 2018/0004535 A1 · METHOD AND SYSTEM FOR BOOTING AUTOMOTIVE ELECTRONICS IN AN ELECTRONIC CONTROL UNIT OF AN AUTOMOBILE

Abstract

Disclosed is a method and system for achieving faster booting of automotive electronics in ECU 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, and diagnostic 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.

A method for booting automotive electronics (123) in an Electronic Control Unit (ECU) (101) of an automobile, the method comprising:

implementing, by an electronic system (102), an Open Systems and their interfaces for the Electronics in motor vehicles (OSEK) based Controller Area Network (CAN) stack (117) in each of booting phases (201) of the ECU (101), wherein the OSEK based CAN stack (117) is stored in a memory mapped region (113) of the ECU (101);
creating, by the electronic system (102), a data structure (119) that stores information pertaining to at least runtime information, state information, message buffers, and diagnostic session state, wherein the data structure (119) is stored in the memory mapped region (113) of the ECU (101);
and
executing, by the electronic system (102), one or more instructions of the OSEK based CAN stack (117) for booting the automotive electronics (123) in the ECU (101) based on the information stored in the data structure (119), wherein the one or more instructions are executed across each of the booting phases (201) of the ECU (101).

1 more element

An electronic system (102) for booting automotive electronics (123) in an Electronic Control Unit (ECU) (101) of an automobile, the electronic system (102) comprising:

a processor (107);
and
a memory unit (105) communicatively coupled to the processor (107), wherein the memory unit (105) stores processor-executable instructions, which, on execution, causes the processor (107) to:
implement an Open Systems and their interfaces for the Electronics in motor vehicles (OSEK) based Controller Area Network (CAN) stack (117) in each of the booting phases (201) of the ECU (101), wherein the OSEK based CAN stack (117) is stored in a memory mapped region (113) of the ECU (101);
create a data structure (119) that stores information pertaining to at least runtime information, state information, message buffers, and diagnostic session state, wherein the data structure (119) is stored in the memory mapped region (113) of the ECU (101);
and
execute one or more instructions of the OSEK based CAN stack (117) for booting the automotive electronics (123) in the ECU (101) based on the information stored in the data structure (119), wherein the one or more instructions are executed across each of the booting phases (201) of the ECU (101).
