Problems solved by technology
However, when the vehicle is in a traffic jam, the driving speed of the vehicle is very low, and the speed of the vehicle cannot meet the activation conditions of the range extender, and the vehicle will always run only on the power of the power battery.
This situation will lead to a large power loss of the power battery, and the risk of vehicle power attenuation is greater

Embodiment Construction
[0029] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.
[0030] In a first aspect, embodiments of the present disclosure provide a vehicle range extender control method, such as figure 1 As shown, the method mainly includes:
[0031] 101. Monitor the speed of the vehicle.
[0032] In practical applications, during the driving process of the vehicle, the speed of the vehicle will vary with the driving conditions it is in, so that the vehicle runs at a speed suitable for the drivi...

The embodiments of the present disclosure disclose a method and device for controlling a range extender of a vehicle, which relate to the technical field of automobiles, and the main purpose is to control the start and stop of the range extender under a traffic jam condition, so as to maintain the power of the vehicle power battery under the traffic jam condition . The main technical solutions include: monitoring the speed of the vehicle; when monitoring that the vehicle is traveling at a speed higher than a preset first speed threshold and changing to a speed lower than a preset second speed threshold, judging that the vehicle is traveling at a high speed. Whether the continuous driving duration at the speed at the first speed threshold is less than a preset first duration threshold, where the first speed threshold is greater than the second speed threshold; If the continuous driving duration at the speed of the speed threshold is less than the first duration threshold, the range extender is activated; if the continuous driving duration of the vehicle at a speed higher than the first speed threshold is not less than the first duration threshold, no Start the range extender.
Description
technical field [0001] Embodiments of the present disclosure relate to the technical field of automobiles, and in particular, to a method and device for controlling a vehicle range extender. Background technique [0002] As people pay more and more attention to environmental protection, electric vehicles have been widely used in people's lives, and extended-range electric vehicles use the range extender to supply power to the vehicle's power battery when the power of the vehicle's power battery is low, and the battery life is better. , which became the main application of electric vehicles. [0003] At present, in the start-stop control strategy of the range extender, the start-stop timing of the range extender is determined according to the vehicle speed, the SOC (State of Charge, state of charge) of the vehicle, and the required power. However, when the vehicle is in a traffic jam, the speed of the vehicle is very low, and the speed of the vehicle cannot reach the startin...
