Problems solved by technology

[0005] After researching the existing technology, the inventor found that the development of automobile products is relatively sufficient at present, and the room for further improvement is relatively small
In the case of different road conditions and resistance, it is difficult to judge the farthest distance traveled by a unit of electric energy even if the driver has a lot of experience in artificially judging the speed of the most energy-saving vehicle, that is, it is difficult to judge how much to use. High speed can save power

Embodiment 1

[0023] The embodiment of the present invention provides a system for automatically saving electric energy, which can be applied to all vehicles that adopt an acceleration controller. Taking the application in automobiles as an example, the system for automatically saving electric energy judges the current vehicle speed and the actual power used relationship, to determine whether the current vehicle speed is the most energy-saving driving speed, and thus increase or decrease the acceleration controller, thereby achieving the purpose of saving electric energy.

[0024] see figure 2 , the automatic power saving system includes:

[0025] The actual used power detection device 201 is used to detect the actual used power of the vehicle in the current state, and the actual used power includes the electric energy consumed by the vehicle in a unit time.

[0026] Specifically, the actually used power detection device 201 can be two electric energy measuring sensors, which are arranged...

Embodiment 2

[0042] The embodiment of the present invention provides a method for automatically saving electric energy, which is described on the basis of the system for automatically saving electric energy provided in Embodiment 1, and can be applied to all vehicles that use accelerator pedals, and the application in automobiles is For example, through the relationship between the current vehicle speed and the actual power used, it is judged whether the current vehicle speed is the most energy-saving driving speed, and thus the driving speed is increased or decreased to achieve the purpose of saving electric energy. see image 3 , the method provided by the embodiment of the present invention is as follows:

[0043] 301: Detect the actual used power and driving speed of the vehicle in the current state, where the actual used power is the electric energy consumed by the vehicle per unit time.

[0044] Specifically, the actually used power detection device 201 may be two electric energy me...

Abstract

The invention discloses a vehicle automatic electric energy saving system and a vehicle automatic electric energy saving method. The system comprises an actual service power detection device, a driving speed signal detection device and an electric energy saving judgment control device, wherein the actual service power detection device is used for detecting the actual service power of a vehicle in the current state; the driving speed signal detection device is used for detecting the current driving speed of the vehicle; and the electric energy saving judgment control device is used for judging whether the current driving speed is the driving speed which saves the electric energy most according to the actual service power and the current driving speed, and if the current driving speed is not the driving speed which saves the electric energy most, judging whether acceleration or deceleration is needed for realizing better utilization of the electric energy and transmitting a control signal to an acceleration and deceleration control device to increase or reduce the driving speed of the vehicle. The embodiment of the invention judges whether the current driving speed is the driving speed which saves the electric energy most according to the relationship between the current driving speed and the actual service power, so that the vehicle is accelerated or decelerated and the driving speed is gradually adjusted to the speed for saving the electric energy most so as to save the electric energy.

Description

technical field [0001] The invention relates to the technical field of electric drive vehicle control, in particular to a system and method for automatically saving electric energy. Background technique [0002] The problem of energy utilization has always been an important aspect in the field of energy-saving technology, and improving energy utilization can achieve the purpose of saving electric energy. Technologies to save power are usually considered from the following aspects: [0003] The first is the development of automobile products, improving automobile related products by reducing the weight of the body, reducing the running resistance of the motor, reducing the drag coefficient, etc.; and saving energy through energy recovery and reuse to achieve the purpose of saving electric energy. [0004] The second is to artificially improve driving skills, and achieve the purpose of saving electric energy through some driving habits that save electric energy. During the d...
