The Built-in Hybrid Device for Automotive Seat

摘要

Fujikura has developed and manufactured some advanced sensing devices for a seat belt reminder (SBR) to detect a passenger or an object and those to determine the physique and sitting position of a passenger using a membrane circuit technology. With recent trends in the automotive industry such as the introduction of self-driving systems and electric vehicles (EVs), built-in electronic control systems and sensing devices have been developed rapidly both inside and outside of the car industry. These new products are much more sophisticated than conventional products in ensuring a safe and comfortable driving environment, being expected to be lightweight, space-saving and energy-saving and have multi-functions to enable sensing and monitoring. Currently, we are developing a hybrid device that combines different functions, in addition to the passenger detection device, including seat heating, radio communication of obtained information, and the detection of biological information (breathing, heart rate) of a driver. This paper describes a hybrid device, which consists of an SBR and a seat heating unit using a new circuit board as the platform.
