Abstract: A method for simultaneously extracting Lycopene and Citrulline from a watermelon includes: separating the rind and the pulp of the watermelon, preprocessing the rind, and using the preprocessed rind to extract the Citrulline; subjecting the pulp to biological enzymolysis and filtering, centrifuging a filtrate, using a precipitate and a filter residue obtained after the centrifuging to extract the Lycopene, and using a supernatant obtained after the centrifuging to extract the Citrulline. By using the method for synchronously extracting Lycopene and Citrulline from the watermelon of the present invention, about 0.5 kg of Lycopene (6% content) and more than 1.2 kg of Citrulline which are worthy of nearly ten thousand yuan can be extracted from each ton of imperfect watermelons, the economic benefit of each ton of watermelons can be increased by more than 5000 yuan after extraction costs are deducted, and the method is high in economic benefits.

Abstract: A vehicle controlling method which includes detecting an engagement of a vehicle tire with a rumble strip of a road, and performing first and second vehicle controls. The first vehicle control includes operating a controller to control movement of the vehicle after the vehicle tire has disengaged from the rumble strip to bring the vehicle tire back into engagement with the rumble strip. The second vehicle control includes operating the controller to continue to control movement of the vehicle to maintain the vehicle tire in engagement with the rumble strip after the vehicle tire has been brought back into engagement with the rumble strip.
