Patent number: 11654901Abstract: A control unit determines whether a rapid acceleration pedal depression operation has been performed. The control unit determines whether a low impact collision has occurred. When it is determined that the rapid acceleration pedal depression operation has been performed and the low impact collision has occurred, the control unit executes a secondary collision damage mitigation control. Consequently, the secondary collision damage mitigation control can be appropriately executed even when a collision that does not cause an air bag to be inflated has occurred.Type: GrantFiled: December 23, 2020Date of Patent: May 23, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke Mase, Hideyuki Usui, Yoshiaki Moriya, Jiro Ohachi, Yuki Tomiku, Yuji Misumi, Tetsuhiro Narita, Masakatsu Onitsuka

Patent number: 11254321Abstract: A driving assist apparatus comprises a driver monitor sensor which detects a state of a driver of an own vehicle installed with the driving assist apparatus. The apparatus determines whether the driver is in a drowsy state, based on the state of the driver detected by the driver monitor sensor. The apparatus determines that a light collision occurs when a light collision determination condition that at least one collision index value representing a level of a collision of the own vehicle is larger than a light collision determination threshold at which an airbag is not developed, is satisfied. The apparatus executes a secondary collision damage mitigation control to apply a braking force to the own vehicle or limit a driving force applied to the own vehicle when determining that the driver is in the drowsy state, and the light collision occurs.Type: GrantFiled: September 9, 2020Date of Patent: February 22, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke Mase, Hideyuki Usui, Yoshiaki Moriya, Jiro Ohachi, Yuki Tomiku, Yuji Misumi, Tetsuhiro Narita, Masakatsu Onitsuka

Detecting wireless noise within time period in which no data is purposefully wirelessly communicated
Patent number: 9184856Abstract: Wireless noise is detected within a time period specifically held after a data packet is wirelessly communicated, where no data is purposefully wirelessly communicated during this time period. The time period may be an inter-frame space (IFS) period within which no data is to be wirelessly communicated, and that is a period waited for prior to accessing a wireless medium over which data is wirelessly communicated. One or more actions are performed to counteract the noise. The frequency at which a liquid crystal display is being driven may be decreased so that harmonics caused thereby that caused the noise are no longer within the wireless communication frequency range. An opposite-in-phase version of the noise may also or alternatively be combined with a signal when data is subsequently wirelessly received. The signal includes a data component and a noise component, the opposite-in-phase version of the noise canceling out the noise component.Type: GrantFiled: January 26, 2005Date of Patent: November 10, 2015Assignee: Lenovo Enterprise Solutions (Singapore) PTE.
