Patent ID: 8047315

Claim:
A driving device that is equipped with a motor having power input and output capabilities, said driving device comprising: a gear change transmission assembly that has a power transmission mechanism and converts the output power of the motor by gear change and transmits the converted power to a driveshaft; a lubrication structure that stores and uses a lubricating medium to lubricate at least the power transmission mechanism of the gear change transmission assembly and is arranged to enable heat exchange between at least part of the lubricating medium with the motor; an upon-request control module that drives and controls the motor upon a certain request to enhance the heat exchange between the lubricating medium and the motor and thereby accelerate a temperature rise of the lubricating medium; and a locking mechanism that locks the driveshaft in a non-rotatable state, wherein said upon-request control module controls the motor and the locking mechanism to heat up the lubricating medium through the heat exchange with the locked driveshaft in the non-rotatable state.
