Embodiment Construction
[0049] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.
[0050] An embodiment of the present disclosure provides a method for controlling a range extender. The method is applied to a range-extended electric vehicle, that is, a range-extender is installed in a pure electric vehicle. In this way, the power system of the extended-range electric vehicle is as follows: figure 1 As shown, it mainly includes a vehicle controller 1, a motor 2, a po...

The invention relates to a control method and device of a range extender, is applied to a range extending type electric car, and belongs to the field of hybrid electric car control. Working of the range extender needs to meet the requirements of a dynamic property, the economical efficiency, the comfort and the safety of the car and the subjective demands of a driver. In the control method and device of the range extender, the working modes of the car are divided into a force starting mode, a force shut down mode, an electric mode and an automatic mode. The driver can achieve subjective demands by changing the working modes, and under different working modes, the emphases of control over the range extender are different. When a whole car controller controls the range extender, working of the range extender is achieved according to battery electricity quantity such as a low electricity quantity danger area, a low electricity quantity alarming area, a power protection area and a chargingpermittable area, according to the car speed such as a high speed permittable working area and a low speed prohibition working area, and by referencing various kinds of signals such as the battery electricity quantity, the car speed and failures. By adopting the control method and device, control over the range extending type electric car at the aspects of the requirements of the dynamic propertyand the economical efficiency and the subjective demands of the driver can be relatively convenient.
Description
technical field [0001] The present disclosure relates to the technical field of automobiles, in particular to a control method and device for a range extender. Background technique [0002] With the continuous development of the automobile industry, more and more electric vehicles are favored by people. However, pure electric vehicles have problems such as long charging time and short mileage on a single charge. The advantages have become the development trend of electric vehicles. [0003] The range-extender electric vehicle is to install a range extender in the pure electric vehicle. The power system of the range-extend electric vehicle mainly includes an electric motor, a power battery and a range extender. Both the range extender and the power battery can be used as the energy of the motor. The source, the two can drive the motor to work at the same time, or can drive the motor to work alone, so that the mileage can be improved. [0004] In the process of realizing the...
