Publication number: 20230123391Abstract: A tea spirit and a method for preparing the same are provided. The method comprises steps crushing tea leaves and soaking the crushed tea leaves in a solvent to obtain a tea suspension; subjecting the tea suspension to distillation under reduced pressure to obtain a tea aroma extract and a remaining tea pulp; filtering the tea pulp to obtain a tea soup, and subjecting the tea soup to concentration under reduced pressure and filtering the tea soup to obtain a filtrate; adsorbing the filtrate with macroporous adsorption resin, then adding food-grade anhydrous alcohol, letting the resultant mixture stand, separating solid from the mixture and drying the solid to obtain a tea theanine extract; and mixing the tea aroma extract and the tea theanine extract with Chinese baijiu to obtain the tea wine. The tea wine as obtained has both tea aroma and wine aroma, and also has an improved intoxication tolerance time.Type: ApplicationFiled: October 20, 2022Publication date: April 20, 2023Inventors: Caihong SHEN, Miao LIU, Feng LIN, Huafang FENG, Yu LAN, Xiaonian CAO, Qingqing LIU, Xiaogang LIU, Yanfei XIONG, Yong WAN, Yong YANG, Tianchi CAO, Xudong ZHAO, Songtao WANG, Bo DENG, Lei ZHENG, Xiangyun LEI, Tao ZHENG

Patent number: 10543818Abstract: The embodiments of the present application disclose a stability control system and a stability control method for a four-wheel drive electric vehicle and the four-wheel drive electric vehicle. In the stability control system, when the lateral acceleration is equal to or greater than an acceleration threshold, at least one of a first braking force signal, a second braking force signal, a first logic signal and a second logic signal is obtained. When the first logic signal is obtained, the body of the electric vehicle is controlled to keep stable. When the first braking force signal and the second logic signal are obtained, a motor is controlled to apply braking force to an outside front wheel. When the second braking force signal and the second logic signal are obtained, motors are controlled to apply braking force to the outside front wheel and an inside rear wheel.Type: GrantFiled: August 10, 2016Date of Patent: January 28, 2020Assignee: BYD COMPANY LIMITEDInventors: Yubo Lian, Heping Ling, Fanliang Meng, Yanfei Xiong, Mingchuan Shi

Patent number: 10322718Abstract: A vehicle stability control system includes a signal collection sensor and a vehicle controller (10). The signal collection sensor is configured to collect a vehicle condition information parameter, and the vehicle controller (10) is configured to calculate a control yaw moment according to the vehicle condition information parameter. The control yaw moment is used to cancel a difference between an estimated yaw moment and an actual yaw moment. The vehicle controller (10) is further configured to determine according to the vehicle condition information parameter whether the vehicle (100) is in a stable region or a non-stable region in the case of tire blow-out, and allocate the control yaw moment to four wheels (101) according to a vehicle stability condition, thus implementing vehicle stability control. A vehicle stability control method and a vehicle (100) with the vehicle stability control system are also disclosed.Type: GrantFiled: August 18, 2016Date of Patent: June 18, 2019Assignee: BYD COMPANY LIMITEDInventors: Yubo Lian, Heping Ling, Ning Wang, Yanfei Xiong, Ting Wen
