Claim 7:
8. The system according to claim 7, wherein the vehicle is pre-configured with a reducing-regulation condition; and the operation comprises:
a first controlling submodule configured for, when the energy-recovery signal is detected and the current vehicle speed is greater than the inflection-point vehicle speed, controlling the reducing-regulation condition to be in an activated state;
when the energy-recovery signal is not detected, controlling the reducing-regulation condition to be in a turning-off state;
when the energy-recovery signal is detected and the current vehicle speed is less than or equal to the inflection-point vehicle speed, controlling the reducing-regulation condition to maintain being in a current state;
when the energy-recovery signal is detected and the reducing-regulation condition is in the activated state, according to the available-charging-power upper-limit value and the first target-recovery-power upper-limit value, determining the reduction proportion of the first energy-recovery-torque curve; and
when the energy-recovery signal is detected and the reducing-regulation condition is in the turning-off state, determining the reduction proportion of the first energy-recovery-torque curve to be 1; and
determining a proportional factor by using a ratio of the available-charging-power upper-limit value to the first target-recovery-power upper-limit value; and
acquiring a predetermined correction factor, and determining the reduction proportion by using the proportional factor and the predetermined correction factor.
