Fuel generator controller and control method on basis of oil-electric hybrid electric vehicle

Abstract

The invention discloses a fuel generator controller and a control method on the basis of an oil-electric hybrid electric vehicle. The controller comprises a microprocessor, an electric door lock state detector, an analog / digital (A / D) converter, a direct current voltage detector, a direct current detector, a temperature detector, a generator starting-stopping driver, an electronic switch module and a throttling actuator. The electric door lock state detector is connected with the microprocessor, the direct current voltage detector, the direct current detector and the temperature detector are connected with the microprocessor through the A / D converter, and the generator starting-stopping driver is connected with the microprocessor and the electronic switch module. The microprocessor controls starting, stopping and generated energy of a fuel generator according to stress optical coefficient (SOC) value of a storage battery pack and uphill and downhill running condition of the electric vehicle. The controller can control the fuel generator to charge the storage battery pack appropriately and accurately according to the SOC value of the storage battery pack, prevents the storage battery pack from being overcharged or overdischarged, and prolongs service life of the storage battery pack.

Description

technical field [0001] The invention belongs to the control field of a hybrid electric vehicle, and in particular relates to a fuel generator controller and a control method based on a hybrid electric vehicle. Background technique [0002] With the development of human society, energy and the environment are putting more and more pressure on human beings, and the call for improving the living environment of human beings is getting louder and louder. In order to adapt to this development trend, countries all over the world have increased the demand for hybrid electric vehicles. The intensity of development. However, the existing gasoline-electric hybrid electric vehicle cannot accurately control the start-stop and power generation of its fuel generator. The fuel generator is likely to cause overcharging when charging the battery pack, which will damage the battery and make the electric vehicle run after the battery pack is charged. The mileage is not long enough; the fuel ge...

Problems solved by technology

However, the existing gasoline-electric hybrid electric vehicle cannot accurately control the start-stop and power generation of its fuel generator. The fuel generator is likely to cause overcharging when charging the battery pack, which will damage the battery and make the electric vehicle run after the battery pack is charged. The mileage is not long enough; the fuel generator cannot change the power generation according to the uphill and downhill driving conditions of the electric vehicle. Once the available power is insufficient when the electric vehicle is driving uphill, it will cause driving difficulties, and excessive power consumption will also cause damage to the battery. , shorten the life of the battery, or even deflagration
