1. A control system for a hybrid electrical vehicle, comprising:
- a transmission device connected with wheels of the hybrid electrical vehicle;
an engine power subsystem connected with the transmission device;
a motor power subsystem connected with the transmission device; and
a control module connected with the engine power subsystem and the motor power subsystem, wherein the control module is configured to control the hybrid electrical vehicle to operate in a hybrid electrical-economical mode by controlling the engine power subsystem and the motor power subsystem and to control the hybrid electrical vehicle to operate in a first manner if a current slope detected by the hybrid electrical vehicle is less than or equal to a minimum slope and a current electric quantity of a power battery of the motor power subsystem is less than or equal to a first electric quantity threshold or if the current slope detected by the hybrid electrical vehicle is less than or equal to the minimum slope and a maximum allowable discharge power of the power battery is less than or equal to a first power threshold.

6. A control method for a hybrid electrical vehicle, comprising:
-
controlling the hybrid electrical vehicle to operate in a hybrid electrical-economical mode by controlling an engine power subsystem and a motor power subsystem when the hybrid electrical vehicle is running; detecting a current electric quantity of a power battery of the motor power subsystem, a maximum allowable discharge power of the power battery, and a current slope of the hybrid electrical vehicle; and controlling the hybrid electrical vehicle to operate in a first manner based on determining that the current slope of the hybrid electrical vehicle is less than or equal to a minimum slope and the current electric quantity of the power battery is less than or equal to a first electric quantity threshold or the current slope of the hybrid electrical vehicle is less than or equal to the minimum slope and the maximum allowable discharge power of the power battery of the motor power subsystem is less than or equal to a first power threshold. - View Dependent Claims (7, 8, 9, 10)
