Problems solved by technology

According to the characteristics of commercial electric vehicles, after the driver arrives at the distribution point, he will open the tailgate to carry out the cargo handling work. During the handling process, the tailgate is always open, and the cold or warm air will escape through the door. The car air conditioner It will always work at the maximum power that is currently turned on, which is a large proportion of ineffective energy consumption for electric vehicles, resulting in a reduction in the driving range of commercial electric vehicles

Embodiment 1

[0049] Implementation steps for entering high temperature energy saving mode:

[0050] 1. The ambient temperature measurement module transmits the temperature potential to the air conditioning controller module (ACM) through the signal line, and the air conditioning controller module (ACM) converts the physical signal of the potential into a digital signal and transmits it to the vehicle controller module (VCU). The value of the digital signal is logically judged with the preset threshold (25°C) in the vehicle controller module (VCU). When the value is greater than the preset threshold (25°C), the vehicle controller module (VCU) checks the air conditioning control. Whether there is a power request for the power supply module (ACM);

[0051] 2. When the vehicle controller module (VCU) detects the power request of the air conditioning controller module (ACM), the vehicle controller module (VCU) further checks the wheel speed signal, and the wheel speed sensor transmits the tire ...

Embodiment 2

[0057] Implementation steps for entering low temperature energy saving mode:

[0058] 1. The ambient temperature measurement module transmits the temperature potential to the air conditioning controller module (ACM) through the signal line, and the air conditioning controller module (ACM) converts the physical signal of the potential into a digital signal and transmits it to the vehicle controller module (VCU). The value of the digital signal is logically judged with the preset threshold (10°C) in the vehicle controller module (VCU). When the value is less than the preset threshold (10°C), the vehicle controller module (VCU) checks the air conditioning control. Whether there is a power request for the power supply module (ACM);

Abstract

The invention discloses a commercial vehicle air conditioner control energy-saving method based on user scenario, and the method comprises the steps: limiting the request power of an air conditioner of a commercial vehicle in response to the external environment temperature being lower than a first temperature or higher than a second temperature and the commercial vehicle being in a third state; in summer high-temperature weather or winter low-temperature weather, when the commercial electric vehicle unloads, the rear door can be opened to facilitate unloading, in most cases, people do not mainly need to turn off an automobile air conditioner, the automobile air conditioner can run at high load, a large amount of electric energy is consumed, the driving mileage of the commercial electric vehicle is reduced, and the service life of the commercial electric vehicle is prolonged. According to the commercial vehicle air conditioner control energy-saving method based on user scenario, the high-temperature energy-saving mode is started in the high-temperature environment or the low-temperature energy-saving mode is started in the low-temperature mode, so that the useless energy consumption ratio is reduced, the energy consumption efficiency of the commercial electric vehicle is improved, and the purpose of increasing the driving range is achieved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an energy-saving method for air-conditioning control of commercial vehicles based on user scenarios. Background technique [0002] Commercial electric vehicles are mainly used in the urban logistics and transportation industry, and the driving range limits the development of commercial electric vehicles to a large extent. Under the high temperature weather in summer or the low temperature weather in winter, the driving range of commercial electric vehicles will be seriously challenged due to the increase of air-conditioning load. According to the characteristics of commercial electric vehicles, after the driver arrives at the distribution point, the driver will open the tailgate to carry out the transportation of goods. During the process of transportation, the tailgate is always open, and the air-conditioning or heating will escape through the door. It will always w...
