What is written in automotive software?

Question

Java

Are all these navigators, music players, electronic devices, etc. made in java?

Answer 1

In Java, they usually make a GUI + media center. And even that is not always in Java. The mediator itself communicates with the car via the CAN bus, sometimes, in rare cases, also via ethernet (hello Tesla). On-board computers, sensors, suspension, brake, and engine control computers sit on the CAN bus. All this economy can be implemented both in the FPGA hardware (verilog), and on the SOC (written in C / C ++).
In a modern car, there are from two to 15 computers for various purposes, or even more.

Well, in general, for the keyword automotive

Answer 2

The "brains" of the machine themselves are brutal real-time systems. And they are almost certainly written in C, maybe pluses or ADA. A music player may not have a program at all, but everything will be implemented in hardware. Hence VHDL/Verilog and others like them. Fortune telling on coffee grounds, in short.
