Problems solved by technology

[0006] Although the above-mentioned "a display device for a hybrid electric vehicle" separates many display segments to display the driving status of multiple hybrid electric vehicles, which improves the display effect to a certain extent, the driver does not know when the pure electric drive will switch. It is driven by the engine or in parallel, and the vehicle is more fuel-efficient in the pure electric mode, so the above-mentioned "a display device for a hybrid electric vehicle" is difficult to prompt the driver to keep the vehicle in the pure electric mode as much as possible, so it is difficult to guide the driver Rational Operation of Vehicles Improves Economical Efficiency
At the same time, after the power output section is divided into multiple sections, each section represents a different drive. When one section is used, it has nothing to do with the scale of other sections, but the display sections in the power output section are connected in series. Therefore, when indicating During one period of time, it is easy for the driver to take the scales of other periods into account, so it is easy for the driver to misunderstand the current driving ability state of the vehicle, thus causing the driver to misoperate the vehicle
Therefore, it is difficult to reasonably display the running state of the hybrid vehicle in the prior art, and then it is difficult to prompt the driver to operate the vehicle reasonably

Embodiment 1

[0031] Such as figure 1 with figure 2 Shown, a kind of hybrid electric vehicle power meter display method, this method comprises the following steps:

[0032] Vehicle drive display: After the vehicle is started, the driver's demanded power is obtained, and the real-time available power of the motor and the real-time available power of the engine are obtained, and the sum of the current real-time available power of the motor and the real-time available power of the engine is calculated, and the current demanded power accounts for the current real-time available power of the motor. The percentage of the sum of the power and the real-time available power of the engine will be displayed in the power meter by the percentage calculated above. The percentage of the current demanded power to the sum of the current real-time available power of the motor and the real-time available power of the engine, that is, the current demanded power divided by the sum of the current real-time ava...

Embodiment 2

[0054] The structure and principle of the second embodiment are basically the same as those of the first embodiment, except that the instrument controller 5 is connected to the accelerator pedal switch, which is a switch that triggers an output signal when the accelerator pedal is fully depressed and further depressed , The instrument controller 5 is also connected to the engine controller 3, the motor controller 2 and the air conditioner controller. Satisfying any of the conditions that the accelerator pedal switch sends a trigger signal, the engine controller 3 sends a self-starting engine signal, the motor controller 2 sends a motor failure message, the air conditioner controller sends a request to start the engine signal, and the engine controller 3 sends an engine prohibition shutdown. In one case, the instrument controller 5 controls the indicator mark 9 corresponding to the engine start-stop flag in the power meter to point to the 10% scale. When any one of the above co...

Embodiment 3

[0056] The structure and principle of the third embodiment are basically the same as that of the first embodiment, except that the power meter display interface displays numbers and symbols, and the calculated current demand power accounts for the percentage of the sum of the current real-time available power of the motor and the real-time available power of the engine It is expressed directly by numbers, such as displaying "41%". Similarly, the engine start and stop flags are displayed with numbers and symbols, such as "engine start and stop position: 40%", and the energy recovery power percentage is also directly displayed with numbers and symbols, "Energy recovery: 50%". The engine running sign 12 and the motor running sign 11 are located on both sides of the displayed numbers. Through the above settings, the display is more intuitive, and it is convenient for the driver to understand the running state of the vehicle. The vehicle controller 1 obtains the actual power feedb...

Abstract

The invention provides a hybrid electric vehicle power meter display method and system, and belongs to the technical field of hybrid electric vehicles. The problem that in the prior art, the running state of a hybrid electric vehicle is difficult to reasonably display is solved. The invention discloses a hybrid electric vehicle power meter display method comprises the following steps: calculatingthe percentage of the current required power in the sum of the current motor real-time available power and the engine real-time available power, and displaying the percentage in a power meter; and calculating the percentage of the maximum working power when the current motor is independently driven in the sum of the real-time available power of the current motor and the real-time available power of the engine, and displaying the percentage in a power table. The hybrid electric vehicle power meter display system comprises a vehicle control unit, a motor controller, an engine controller and an instrument controller, the motor controller and the engine controller are respectively connected with the vehicle control unit, and the instrument controller is connected with the output end of the vehicle control unit. The driving state of the hybrid electric vehicle can be reasonably displayed to prompt a driver to reasonably operate the vehicle.

Description

technical field [0001] The invention belongs to the technical field of hybrid electric vehicles, and relates to a method and system for displaying a power meter of a hybrid electric vehicle. Background technique [0002] The power system of a hybrid electric vehicle is composed of multiple power sources. The driving mode includes pure electric drive, that is, the motor consumes electricity to drive the vehicle alone, pure oil drive, that is, the engine consumes fuel to drive the vehicle alone, and hybrid drive, that is, the motor and the engine work simultaneously to drive the vehicle. [0003] Compared with traditional fuel vehicles, hybrid vehicles not only have the advantages of good fuel engine power, quick response and long working hours, but also have the advantages of no pollution and low noise of electric motors, achieving the best match between engine and electric motor. Therefore, more and more people choose hybrid vehicles as their first choice for travel. [000...
