Patent number: 11989078Abstract: A vehicle control device and a method thereof are provided. A master processor and a slave processor simultaneously receive, monitor or process signals of a vehicle, a power management module monitors the master processor via a first watchdog signal, and the master processor monitors the slave processor via a second watchdog signal. When the power management module sends the first watchdog signal to the master processor and no response message is received, the power management module sends a first reset signal to reset the master processor, and when the master processor sends the second watchdog signal to the slave processor and no response message is received, the master processor sends a second reset signal to reset the slave processor. When the master processor and the slave processor are abnormal, a forced wake-up module outputs a high level signal to forcibly wake up the master processor and the slave processor.Type: GrantFiled: June 7, 2022Date of Patent: May 21, 2024Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Yu-Long Wang, Nan-Hsiung Tseng, Yi-Lun Cheng

Publication number: 20120100944Abstract: An electrical control belt continuously variable transmission system controls a movable driving half-pulley or movable driven half-pulley initiatively, by changing a driving interval between the movable driving half-pulley and a fixed driving half-pulley or a driven interval between the movable driven half-pulley and a fixed driven half-pulley, respectively, depending on different statuses, in order to adjust a velocity ratio. By manipulating the movable driving half-pulley or the movable driven half-pulley, the system may further form a driving gap between the movable driving half-pulley and a transmission belt or a driven gap between the movable driven half-pulley and the transmission belt, such that the power is cut off. Clamping the movable driving half-pulley or the movable driven half-pulley to the transmission belt may restore the outputting of the power.Type: ApplicationFiled: December 20, 2010Publication date: April 26, 2012Applicants: Kwang Yang Motor Co., Ltd., INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Huan-Lung GU, Chin-Hone Lin, Pan-Hsiang Hsieh, Shao-Yu Li, Nan-Hsiung Tseng, Sen-Hsien Chang, Chuan-Ming Su, Chien-Hung Lai
