<P>PROBLEM TO BE SOLVED: To provide an electronic synchronous transmission reducing the addition of components to attain the temperature rise of lubricating oil without worsening fuel consumption. <P>SOLUTION: The electronic synchronous transmission includes a lubricating oil temperature sensor 8 detecting the temperature of lubricating oil L; a vehicle driving state detecting means 9 detecting the driving state of a vehicle; a shift period detecting means 10 detecting whether a shift control means 7 is in a shift period; and a lubricating oil temperature rise control means 11 operating a countershaft brake 6 to raise the temperature of the lubricating oil L if the driving state of the vehicle is in a speed reducing state and the shift control means 7 is not in the shift period when the temperature of the lubricating oil is a set value or less. <P>COPYRIGHT: (C)2011,JPO&INPIT |
