AVAS is a alert device that developed by QUFU TEMB, which can make use of the easily recognized sound such as engine sound, music sound or motor sound, to remind passers-by of a vehicle moving in approach and pay attention. The products controlled by the microcomputer, Sound source type and sound level can be adjusted according to the requirements of the carmakers. The warning sound can be sounded at a low speed according to the speed of the vehicle and the gear position, which improves the driving comfort while solving passers-by safety.
TEMB Automotive provides advanced Acoustic Vehicle Alerting Systems designed as reliable pedestrian warning system solutions for modern electric and hybrid vehicles.
As electric vehicles produce very low noise during low-speed operation, pedestrians and cyclists may have difficulty detecting approaching vehicles. A professional pedestrian warning system AVAS generates external acoustic signals to improve vehicle awareness and enhance road safety.
The TEMB AVAS04-01 integrated project product combines compact design, stable acoustic performance, and automotive-grade reliability, providing vehicle manufacturers with an effective solution for pedestrian safety requirements.
The TEMB AVAS04-01 is an automotive pedestrian warning system based on Acoustic Vehicle Alerting System technology. It is designed for electric vehicles and hybrid vehicles that require external sound generation during low-speed driving conditions.
The system communicates with the vehicle control unit and produces customized warning sounds according to vehicle speed, driving conditions, and OEM requirements.

Traditional vehicles naturally produce engine and mechanical noise, while electric vehicles operate much more quietly, especially at low speeds. This creates a potential safety challenge for pedestrians.
A pedestrian warning system AVAS addresses this issue by actively generating external acoustic alerts when the vehicle operates in silent driving conditions.
The working process includes:
● Receiving vehicle information from the control system
● Monitoring vehicle speed and operating status
● Activating acoustic warning signals during low-speed operation
● Providing recognizable sounds for pedestrians and cyclists
TEMB Automotive pedestrian warning system solutions are suitable for different new energy vehicle platforms, including:
● Electric passenger vehicles
● Hybrid electric vehicles
● Plug-in hybrid vehicles (PHEV)
● Electric commercial vehicles
● Electric buses
● Autonomous and special-purpose vehicles
