Embodiment 1

[0050] figure 1 It is a schematic diagram of the test flow for the efficiency test of a pure electric vehicle provided in this embodiment.

[0051] Such as figure 1 As shown, the present embodiment provides a method for testing the efficiency of a pure electric vehicle, comprising the following steps:

[0052] S110, setting a test vehicle speed array and a test torque array of the test vehicle;

[0053]The above-mentioned "test vehicle speed array" refers to a collection of different test vehicle speeds arranged in a certain order when pure electric vehicles perform vehicle efficiency tests. In this embodiment, the test vehicle speed arrays are set to 140km / h, 130km / h, and 120km / h , 110km / h, 100km / h, 90km / h, 80km / h, 70km / h, 60km / h, km / h, 40km / h, 30km / h, 20km / h, 10km / h. During the test, the vehicle speed error was kept within 0.5km / h.

[0054] The above-mentioned "test torque array" refers to the collection of all test torques arranged in a certain order when the pure elect...

Embodiment 2

[0086] Such as Figure 5 As shown, this embodiment provides an electronic device, including:

[0087] at least one processor; and

[0088] a memory communicatively coupled to the at least one processor; wherein,

[0089] The memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor, so that the at least one processor can execute the above method. At least one processor in the electronic device is capable of executing the above method, and thus has at least the same advantages as the above method.

[0090] Optionally, the electronic device further includes interfaces for connecting various components, including high-speed interfaces and low-speed interfaces. The various components are interconnected using different buses and can be mounted on a common motherboard or otherwise as desired. The processor may process instructions executed within the electronic device, including instructions stored in or ...

Embodiment 3

[0096] This embodiment provides a medium, on which computer instructions are stored, and the computer instructions are used to make the computer execute the above method. The computer instructions on the medium are used to cause a computer to execute the above method, thus having at least the same advantages as the above method.

[0097]The media in the present invention may use any combination of one or more computer-readable media. The medium may be a computer readable signal medium or a computer readable storage medium. A medium may be, for example, but not limited to, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, device, or device, or any combination thereof. More specific examples (non-exhaustive list) of media include: electrical connection with one or more wires, portable computer disk, hard disk, random access memory (RAM), read only memory (ROM), erasable Programmable read-only memory (EPROM or flash memory), optical fiber, po...

Abstract

The invention relates to a pure electric vehicle whole vehicle efficiency test method, electronic equipment and a medium. The method comprises the following steps: a test vehicle speed array and a test torque array of a test vehicle are set; the test vehicle speed array comprises at least two test vehicle speeds; torque testing is carried out at each testing vehicle speed, and the torque testing comprises the steps that the limit torque of the vehicle at the current testing vehicle speed is compared with the maximum value of the testing torque in the testing torque array, the torque testing sequence at the current testing vehicle speed is determined, and torque testing is carried out. According to the method, the test torque sequence at different vehicle speeds can be quickly determined through the relation between the vehicle limit torque and the test torque array at different test vehicle speeds, and the efficiency of the whole vehicle efficiency test of the pure electric vehicle is improved.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a method for testing the efficiency of a pure electric vehicle, electronic equipment, and a medium. Background technique [0002] With the increasingly prominent environmental and energy issues, new energy vehicles have become a research hotspot for major automobile manufacturers and R&D institutions in the world. Pure electric vehicles are favored by major automobile manufacturers for their zero-emission characteristics. [0003] How to improve the cruising range of vehicles is a hot issue that has been concerned in the development of pure electric vehicle technology, and the working efficiency of the whole vehicle is a key factor affecting the cruising range of pure electric vehicles, so how to efficiently and accurately test the working efficiency of pure electric vehicles very important. [0004] However, the existing pure electric vehicle efficiency test mostly adopts the dru...
