The invention discloses an engine control method and a power compensation device under a complex working condition, and the method comprises the steps that an unmanned vehicle automatically recognizes the gradient of a current driving road and the current vehicle speed through a sensing module, and transmits the gradient and the current vehicle speed to a vehicle-mounted calculation platform; the vehicle-mounted computing platform of the unmanned vehicle compares the slope of the current driving road and the current vehicle speed with a set vehicle speed expected value; and if the gradient of the current driving road exceeds a threshold value and the current vehicle speed is lower than an expected value, the vehicle-mounted computing platform sends an instruction to the electronic control unit to complete climbing on the difficult slope. The control method provided by the invention is mainly used for the unmanned vehicle encountering the difficult slope working condition during driving or operation, slope information can be effectively recognized, and power compensation can be made in time according to the vehicle condition; the power compensation device can effectively increase the valve lift and the engine power; the potential safety hazards such as engine flameout caused by insufficient power when the unmanned vehicle faces a difficult ramp are effectively solved, and the safety and stability of unmanned driving are improved.
本发明公开了一种复杂工况下发动机控制方法和动力补偿装置,包括:无人车辆利用感知模块自动识别当前行驶道路的坡度和当前车辆速度,并传送至车载计算平台;无人车辆的车载计算平台将与当前行驶道路的坡度、当前车辆速度与设定的车辆速度期望值进行对比;若当前行驶道路的坡度超过阈值且当前车辆速度低于期望值,则车载计算平台向电子控制单元发送指令,完成困难坡爬行。本发明所提出的控制方法主要针对行驶或作业时遇到困难坡工况的无人车辆,可有效识别坡度信息,及时根据车况做出动力补偿;动力补偿装置可有效增加气门升程和发动机动力;有效解决无人车辆面对困难坡道时动力不足带来的发动机熄火等安全隐患,提高无人驾驶的安全性和稳定性。
