Chinese Automaker Seres Patents Voice-Controlled In-Car Toilet
Chinese electric vehicle manufacturer Seres has filed a patent for an innovative in-car toilet system hidden beneath the passenger seat. The device, which can be activated either by manually sliding the seat back or via the voice command "activate toilet function," is designed to address user needs during long trips, camping, or overnight stays in the vehicle. According to patent documents, the system features a ventilation mechanism to direct odors outside and a waste tank that requires periodic emptying. Additionally, it includes a heating element to evaporate urine and dehydrate solid waste, aiming to optimize hygiene and space usage within the cabin. While the concept of installing sanitary facilities in vehicles exists in vans and motorhomes, Seres' design emphasizes discreet integration into standard passenger cars. This move aligns with a broader trend among Chinese EV makers, who are increasingly incorporating sophisticated amenities like karaoke systems, mini-fridges, and massaging seats to attract buyers. Although the patent was granted in April 2026, Seres has not yet announced any production models equipped with this technology, leaving its commercial availability uncertain. The development highlights the competitive innovation landscape in China's automotive sector, particularly in partnership with tech giant Huawei for the AITO brand.
