Vehicle control method, system and vehicle

Abstract

The present invention proposes a vehicle control method, system and vehicle. The method includes the following steps: obtaining the target path selected by the driver and the target temperature inside the vehicle; calculating the power consumption of the first battery required to complete the target path; The power consumption of the second battery required by the target temperature; controlling the air conditioning system of the vehicle according to the current battery power, the power consumption of the first battery and the power consumption of the second battery. The invention can reasonably control the air-conditioning system of the vehicle in combination with the driver's driving road condition requirements, thereby more reasonably allocating the electric energy consumption of the vehicle, effectively reducing the energy consumption of the whole vehicle, prolonging the mileage of driving, and improving the driving performance of the vehicle .

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control method, system and vehicle. Background technique [0002] The driving range of electric vehicles has always been one of the issues that consumers are very concerned about. For an electric vehicle with limited battery capacity, "range anxiety" is a constant problem for drivers. [0003] In view of the above problems, the current electric vehicles basically have the function of calculating the driving range, and the driving range of the vehicle can be estimated by parameters such as the remaining power of the battery. For electric vehicles, its air conditioning system and thermal management system are high-voltage components that consume a lot of electric energy. Usually, the high energy consumption of the vehicle is the air conditioning, heating and cooling functions of the cockpit and the heating and cooling functions of the battery system, and this part o...

Problems solved by technology

Usually, the high energy consumption of the vehicle is the air conditioning, heating and cooling functions of the cockpit and the heating and cooling functions of the battery system, and this part of energy consumption is basically irrelevant to the driving conditions such as the speed of the vehicle, and this part of the energy consumption is also considerable. , for example, the heating power consumption of the cockpit may reach more than 6 kWh per hour. Therefore, the battery power is greatly consumed, which in turn reduces the driving range of the vehicle and affects the driving performance of the vehicle.
