“CASE” (Connected, Autonomous/Automated, Shared, and Electric) are the keywords that represent the trends of the automotive industry. The great changes that will make way for this future of the automotive industry are already underway. Especially in the case of automation and electrification, it is not only convenience but also safety that will be a necessity.
In Japan, the government was among the first to take action in preventing traffic accidents involving elderly drivers, working together with the private sector to promote the use of “Safety Support Cars.” The Safety Support vehicles have advanced safety technologies such as collision damage mitigation brakes, as a way to facilitate safe driving.
The ability to detect and take action is vital for advanced safety technology. Devices also need to be able to let people know when there is danger. Murata's piezoelectric sounder/buzzer has low current consumption and high sound pressure (loud volume) with few drops in sound pressure due to heat load.
