Qt launches new HMI software framework to develop next-generation digital cockpits

Gasgoo Automotive News on June 21, software technology supplier Qt announced a cooperation with auto parts supplier Bosch (Bosch).Bosch will deploy Qt's unified cross-platform Human Machine Interface (HMI) design and development framework to provide automakers with the tools to create solution-ready digital cockpits.The solution provides a turnkey solution for automotive manufacturers (OEMs) looking to develop human-machine interfaces to run on architectures such as AUTOSAR.

With Qt's latest addition to MCUs, Qt can now be developed and deployed to any automotive-grade microprocessor unit (MPU) and microcontroller unit (MCU).The solution can be used in any operating system or software platform environment, including INTEGRITY RTOS, QNX Neutrino RTOS, Android Automotive OS and Automotive Grade Linux (AGL), as well as AUTOSAR CLASSIC, the newest member of the Qt offering.

The collaboration between Qt and Bosch enables OEMs to build entire digital cockpits for the first time and enables Qt HMI to be deployed on top of the AUTOSAR CLASSIC platform.OEMs can maximize graphics computing efficiency and security while reducing bill of materials (BOM) costs.When using Qt, development needs can also be scaled up and down, and software developed with Qt is source code that is reusable and extensible.It increases productivity and reduces time to market.

The collaboration avoids the need to purchase additional hardware, as all functions such as heating, ventilation and air conditioning (HVAC) and power mirrors can be enabled on a single system-on-chip (SoC).Thanks to the integrated HMI and AUTOSAR, the rich user interface of the MPU and MCU will provide end-users with unparalleled visuals when using both safety-critical and non-safety-critical HMIs in the digital cockpit.

Miao Luo, Head of Automotive and Design at Qt, said: "As customers' needs for digital experiences in the car continue to evolve, Qt and Bosch have partnered to provide customers with a solution-ready digital cockpit. This new approach will enable users to access the advanced technologies required by the current industry. Digital cockpit capabilities for an unforgettable experience for all vehicle users. Running a hybrid MPU and MCU model means OEMs will be able to reduce more hardware computing, resulting in cost savings and increased revenue. We are developing a highly competitive and A customizable HMI platform, and we're already seeing OEMs adopt it in commercial production."
