Delphi's innovative electronic warning sounder not only has the advantages of small size, light weight, low power consumption, low cost, but also features lead-free, waterproof, high temperature resistance, can withstand the high temperature and low temperature challenges in the car engine hood . The electronic warning sounder is expected to be the first to be applied in the European market in 2012.

Delphi's new electronic warning sounder uses a single design, weighs only one-third of the traditional multi-body design system, and the power consumption is reduced by 90%, making it the most environmentally friendly solution. Its single-box structure not only helps reduce vehicle design, testing, and manufacturing costs, its smaller size and weight can also simplify vehicle installation. The frequency range of the system is 500Hz-10KHz, which can meet the unique melody selection of each vehicle manufacturer.

For higher quality sound requirements, Delphi also introduced a high-fidelity sound system. The system uses a conical speaker driven by a lightweight magnet and extends the lower limit of the frequency range to 150Hz. This magnet-based system weighs 66% less than conventional speaker systems.

Delphi's two systems are rugged and can be installed in harsh environments under the hood of a car, and integrate a 32-bit microprocessor with flash memory, a connector to the car's data bus, and an audio D-stage loudspeaker. .

The electric car has almost no sound during driving, which poses a safety hazard for pedestrians. With the application of hybrid vehicles and electric vehicles, various regulatory requirements have also been brought up on the agenda.

Beth Schwarting, director of Delphi’s electronic control products business unit, pointed out: “Japan has incorporated regulatory warnings for hybrid and electric vehicle warning sounds, and it is expected that North American and European markets will soon introduce regulations. Delphi’s goal is to Launch new low-cost, environmentally friendly technologies to help OEMs meet market challenges.”

Higher value through system integration

Deidrichvon Behr, general manager of Delphi's European electronic control products business unit, pointed out: "Delphi's new electronic sound system enhances the traffic safety of hybrid and electric vehicles by alerting pedestrians to approach their cars, and can also be integrated into other vehicles. In-vehicle systems bring higher added value to vehicle customers."

As a professional system integrator, Delphi uses its own advantages to integrate the sounder with other systems through the automotive data bus. Vehicle manufacturers can provide sound alerts for multiple situations without having to install multiple sounding systems. For example, the system may perform a series of voice prompts such as the battery needs to be charged by the owner, the confirmation of charging being performed, and the reminder that the owner has been charged.

Delphi is committed to providing high-performance, high-value products for hybrid and electric vehicle manufacturers, and has developed a series of products and technologies for hybrid vehicles and electric vehicles ranging from high-voltage connection systems, remote charging systems, and power electronics. To help automakers improve vehicle performance, reduce costs, simplify installation, and meet new energy challenges.
