A hybrid vehicle control method controls a hybrid vehicle having an electric power source, a vehicle electrical equipment and drive motor to which electric power is supplied from the electric power source. The vehicle electrical equipment and the drive motor are electrically connected to the electric power source via at least a shared harness. When a temperature of the harness is equal to or greater than a predetermined temperature, upper limit values of electric power supplied from the electric power source to the vehicle electrical equipment and the drive motor are both reduced, and a degree of reduction in the upper limit value for the vehicle equipment is greater than a degree of reduction in the upper limit value for the drive motor.
