Patent number: 9446352Abstract: An object of this invention is to provide an atmosphere-cleaning device for vehicles that is capable of restoring the function of an ozone purifying body carried by a vehicle component. Mud, dust, snow-melting agents as well as SOx and NOx are scattered into the atmosphere as a result of being swirled up by a preceding vehicle or due to weather and climate conditions. When such extraneous substances adhere or the like to an ozone purifying body, the purification sites thereof are clogged and the ozone purification function deteriorates. Therefore, when a predetermined removal implementation condition is established, control is executed to inject cleaning liquid from an injector to enhance the fluidity of the extraneous substances and wash the extraneous substances away. The function of the ozone purifying body can thereby be restored.Type: GrantFiled: November 14, 2012Date of Patent: September 20, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Makoto Tomimatsu, Koichi Hoshi, Yoshihisa Shinoda, Kazuhiro Sugimoto, Takuya Ookubo
