The inventiondiscloses a planetary hybrid vehicle energy management control methodand in particular to a switching control method for solving the power and economy of the starting process of the slopeclimbing, belonging to the field of hybrid electric vehicle control technology. Because the torque provided by the drive motor is limited, control strategies for real vehicle applications: as that engine work point is always control on the optimal working curve, the problem that the vehicle power performance is insufficient is caused. According to different work conditions (need to be identified), the engine is divided into two modes of power performance control and economic control. When the engine power performance is controlled, the engine provides as much torque as possible to ensure thevehicle power performance; in order to improve the fuel economy of the vehicle; the engine is controlled on the optimal working curve when the fuel economy is controlled. The energy management controlmethod fully considers the performance of engine and drive motor, makes up for the shortcomings of the widely used engine optimal real-vehicle control strategy, improves the economy and power of thevehicle, and is easy to implement and popularize.
