Publication number: 20150151714Abstract: A vehicle control system includes a wiper, a control portion that outputs a drive command such that the wiper is placed in a first state or a second state that is more restricted than the first state, and a checking portion that checks whether a mobile device is in the vehicle via wireless communication between an onboard device and the mobile device, when a door of the vehicle is opened or closed. If the door is opened while the wiper is in the first state, the control portion performs a first control that switches the operating state of the wiper from the first state to the second state, and then after a period of time for which the check by the checking portion is executed has passed while the wiper is in the second state, the control portion switches the operating state from the second state to the first state.Type: ApplicationFiled: June 7, 2013Publication date: June 4, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Masachika Kamiya

Patent number: 8207817Abstract: An electronic key system which checks, using two-way communication, a key code stored in an electronic key against a key code stored in a lock device that locks an entrance to a predetermined space, and allows an unlocking operation of the lock device if the key code stored in the electronic key matches the key code stored in the lock device, is such that the key code includes an identification code unique to the electronic key and a property code indicative of a property of the electronic key (a master key or an additional key). The lock device erases a key code that includes a property code indicating that the key is an additional key, from among the key codes stored in the lock device, when a predetermined operation (including an operation using the master key) is performed.Type: GrantFiled: May 17, 2006Date of Patent: June 26, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventor: Masachika Kamiya
