Read this white paper to learn how to design heating and cooling systems for HEV/EVs. Acoustic Vehicle Alerting System (AVAS) is an additional element to electrical vehicles that artificially generates a sound which will be generated through loudspeakers or actuators based on vibration of structural elements of the vehicle proportional to vehicles parameters, for example velocity, gas pedal position and gear. At the same time, forward collision warning systems alert drivers when they are approaching a vehicle or obstacle too quickly. An electronic control unit (ECU) is a small device in a vehicle's body that is responsible for controlling a specific function.
