Hybrid electrical vehicle and method for cruising control of the same
First Claim
1. A method for cruising control of a hybrid electrical vehicle, comprising:
- detecting a current speed of the hybrid electrical vehicle;
determining that the current speed of the hybrid electrical vehicle is in a predetermined cruise-speed range;
detecting a cruising signal and a current working mode of the hybrid electrical vehicle, wherein the current working mode of the hybrid electrical vehicle is an electric vehicle (EV) mode;
controlling the hybrid electrical vehicle to enter an EV cruising mode;
detecting that (1) a maximum output power of an electric motor of the hybrid electrical vehicle is less than a first power value or (2) a maximum output torque of the electric motor of the hybrid electrical vehicle is less than a first torque value, wherein the first power value is a first demanded power of the hybrid electrical vehicle in the EV cruising mode cruising at the current speed, and wherein the first torque value is a first demanded torque of the hybrid electrical vehicle cruising at the current speed when the hybrid electrical vehicle is in the EV cruising mode; and
subsequent to detecting that the maximum output power of the electric motor is less than the first power value or the maximum output torque of the electric motor is less than the first torque value, switching the hybrid electrical vehicle from the EV cruising mode to a hybrid electrical vehicle (HEV) cruising mode.
