In order to study the performance of an accumulator during the start up of an electronically controlled hydraulic vehicle, theoretical analysis and establishment of a 1/4 vehicle experimental platform for experimental verification were conducted, in order to study the performance characteristics of the hydraulic circuit during driving. Control experiments show that the accumulator does not affect the acceleration performance and the torque of the hydraulic motor when an electrically controlled hydraulic vehicle is driven. The accumulator can be used as an auxiliary power component to absorb partially wasted energy during driving to improve the energy utilization efficiency. The energy absorbed by the accumulator during driving can increase the maximum speed; the use of the accumulator can alleviate the hydraulic shock at the entrance of the hydraulic motor.
