The invention discloses a pure hydraulic drive vehicle economical efficiency control method which comprises the steps that whether a vehicle moves at a constant speed or not is judged according to the actual vehicle running speed and the target vehicle speed, and if the vehicle does not move at the constant speed at the moment, an economical efficiency basic control strategy is adopted to control the vehicle to accelerate to the target vehicle speed; and after the vehicle speed is increased to the target vehicle speed and enters a constant-speed motion stage, an efficiency compensation strategy is adopted, target vehicle speed tracking is guaranteed through motor displacement compensation, and meanwhile the driving economy of the constant-speed stage is further improved. On the basis that pure hydraulic drive vehicle target speed tracking is achieved, oil consumption in the vehicle running process is reduced, and running economy is improved.

    本发明公开了一种纯液压驱动车辆经济性控制方法,包括,根据车辆实际行驶车速与目标车速判断车辆是否处于匀速运动,如果车辆此时不处于匀速运动则采用经济性基本控制策略,控制车辆加速至目标车速;在车辆速度提升至目标车速进入匀速运动阶段之后,采用效率补偿策略,通过马达排量补偿在保证目标车速跟踪的同时,进一步提高匀速阶段的行驶经济性。本发明在实现纯液压驱动车辆目标车速跟踪的基础上,降低了车辆行驶过程油耗,提高了行驶经济性。
