Electronic Automotive Systems
Motorcycles, cars, and trucks are increasingly powered by networks of embedded systems, each of which is a combination of software and electronics. Some modern vehicles have over one hundred processors and when even one of these electronic automotive systems malfunctions, the results can be deadly. Barr Group is in the business of designing reliable and secure computers and our team of expert software engineers, electrical engineers, and mechanical engineers is intimately familiar with electronic automotive subsystems including:
- Engine control units (ECU) and transmissions
- Anti-lock braking systems (ABS)
- Navigation systems and GPS
- Airbag controllers and electronic data recorders (EDR)
- Advanced driver assistance systems (ADAS)
- Automotive vision systems and self-driving technologies
- Other vehicle safety and security systems
- In-vehicle infotainment (IVI) and telematics like OnStar
- CAN busses and related SAE network protocols
- Hybrid and electric vehicles and battery charging
Barr Group's software experts are familiar with all of the operating systems used by carmakers, including real-time operating systems like OSEK and QNX, and Android/Linux, as well as all programming languages such as assembly, C, C++, and Matlab. And we are just as comfortable with electronic circuits and ASICs and the Verilog and VHDL languages.
