The invention discloses a range extender starting control method and equipment, a range extending type electric car and a storage medium. The method comprises the steps that a starting motor tries tostart an engine at preset first torque value; under the condition that starting of the engine fails at the first torque value, the starting motor tries to gradually increase the starting torque to preset second torque value to start the engine; under the condition that starting of the engine fails at the second torque value, the starting motor tries to maintain the second torque value continuouslyfor the first preset time segment to start the engine; under the condition that starting of the engine fails after continuing for the first preset time segment, the starting motor stops starting dueto the starting failure; and under the condition that the starting motor successfully starts the engine at the first torque value or the second torque value, the starting motor gradually decreases thestarting torque to the third preset torque value and continues for a second preset time segment. The invention further provides a control scheme capable of enabling a range extender to be reliably started.

    本发明公开了增程器启动控制方法、设备、增程式电动汽车和存储介质。该方法包括:使得启动电机尝试以预设的第一扭矩值启动发动机;在以第一扭矩值启动发动机失败的情况下,使得启动电机尝试将启动扭矩逐渐增加到的预设的第二扭矩值以启动发动机;在以第二扭矩值启动发动机失败的情况下,使得启动电机尝试维持第二扭矩值持续第一预设时间段以启动发动机;在持续第一预设时间段启动发动机失败的情况下,使得启动电机因启动失败而停止启动;以及在启动电机以第一扭矩值或者第一扭矩值启动发动机成功的情况下,使得启动电机将启动扭矩逐渐减小到预设的第三扭矩值并持续第二预设时间段。本发明,提供了一种能够使得增程器可靠启动的控制方案。
