The invention provides an agitating lorry upper-installed driving 
system and an agitating lorry upper-installed driving control method. An agitating lorry comprises a vehicle 
chassis and an agitatingbarrel arranged on the vehicle 
chassis. A main engine is arranged on the vehicle 
chassis. The agitating lorry upper-installed driving 
system comprises a motor device, a battery 
assembly and a power generation device. The motor device is in transmission connection with the agitating 
barrel so that the agitating 
barrel is driven to rotate through the motor device. The battery 
assembly is in electricconnection with the motor device. The power generation device is in electric connection with the motor device and provides 
electric energy for the motor device, and the power generation device is inelectric connection with the battery 
assembly so that the battery assembly is charged by the power generation device. According to the technical scheme, the agitating lorry upper-installed driving 
system can run independently and do not need to rely on output power of the main motor of the agitating lorry; working efficiency can be improved efficiently, and the agitating quality of concrete is prevented from being influenced by stop of agitating 
barrel rotation caused by insufficient power; besides, load of the main motor does not need to be increased, and reduction of main engine emission andpollution emission is benefited; and the cost is lowered.
