6 Claims

1. A power distribution management method for a hybrid vehicle, comprising:

receiving an accelerator pedal opening information sent by the hybrid vehicle;

respectively counting, based on the accelerator pedal opening information, a first opening change rate when an accelerator pedal opening is in a starting interval and when the accelerator pedal opening is increased and a second opening change rate when the accelerator pedal opening is in an overtaking interval and when the accelerator pedal opening is increased, wherein the starting interval corresponds to a first preset range of the accelerator pedal opening, and the overtaking interval corresponds to a second preset range of the accelerator pedal opening;

calculating a driver feature coefficient based on the first opening change rate and the second opening change rate; and

sending the driver feature coefficient to the hybrid vehicle, so that the hybrid vehicle determines an accelerator pedal opening threshold based on the driver feature coefficient,

wherein the calculating a driver feature coefficient based on the first opening change rate and the second opening change rate comprises:

calculating a first historical average opening change rate G_q_{_avg}when the accelerator pedal opening is in the starting interval based on the first opening change rate;

calculating a second historical average opening change rate G_c_{_avg}when the accelerator pedal opening is in the overtaking interval based on the second opening change rate; and

calculating the driver feature coefficient according to the following formula based on the first historical average opening change rate G_q_{_avg}and the second historical average opening change rate G_c_{_avg}:

wherein, k_q+k_c=1,

wherein, K is the driver feature coefficient, k_qis a weighting coefficient corresponding to the first historical average opening change rate G_q_{_avg}, k_cis a weighting coefficient corresponding to the second historical average opening change rate G_c_{_avg}, and G_nis a preset opening change rate.
