Head up display

A transparent display that shows information on the front windshield, allowing drivers to keep their eyes on the road, instead of having to look away toward information on the dashboard. This may be using rear projection (a reversed image projected vertically from behind the steering wheel) of transparent mono or… read more

Heterogeneous architecture

A combination of multiple types of processors — such as CPUs, FPGAs, and ASICs—working together in a complementary fashion. Such systems may adhere to a particular standard, or be defined as an open architecture model.


Hardware in the loop simulation combines a system to be tested with a software representation of the platform it will eventually be joined to. These mathematical representations are referred to as the “plant simulation”. The embedded system to be tested interacts with this plant simulation. For example, a HIL simulation… read more

Hill Descent Assist

This feature works with your vehicle’s existing braking systems to block you from going past a certain speed while travelling downhill or on unsteady terrain. In automatic or drive-by-wire vehicles such as electric or hybrid, it may reduce available power to the wheels. If your car begins accelerating past a… read more

Hill Start Assistance

System which helps driver balance engagement of power with any negative forces affecting the vehicle, moving from parked or stopped at a junction up an incline. Sensors in the vehicle are used to detect when a vehicle is on an incline and maintain the brake pressure for a set period… read more


Human-machine interface is responsible for two-way communication between a vehicle and its occupants. An HMI may incorporate touchscreen displays, voice recognition, or integration with mobile devices.
