A control method and system for a vehicle and the vehicle according to an embodiment of the invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of a vehicle according to one embodiment of the invention. As shown in fig. 1, the method comprises the steps of:
step S1: and acquiring a target path selected by the driver and the target temperature in the vehicle.
In a specific example, for example, the current positioning information of the vehicle is obtained through a vehicle-mounted navigation system, then the destination input by the driver is obtained through an information interaction system of the vehicle, the current road condition information is obtained, a planned path is provided according to the current road condition information, and then the driver selects a target path from the provided paths. Further, the driver inputs the required temperature in the vehicle, namely the target temperature in the vehicle, through the information interaction system, so that the air conditioning system can operate conveniently, and the temperature in the vehicle reaches the target temperature in the vehicle.
Step S2: a first battery power consumption required to complete the target path and a second battery power consumption required to reach the target temperature in the vehicle are calculated. That is, the power consumption required for the vehicle to finish the selected target path and the power consumption required for the vehicle interior temperature to reach the vehicle interior target temperature are determined.
Specifically, the required first battery power consumption is determined according to the route information and the road condition information of the target route, and the required second battery power consumption for reaching the target temperature in the vehicle is determined according to the current environment temperature. Specifically, for example, the power consumption required for completing the target path is estimated according to the mileage, road condition, and other information of the selected target path, and the power consumption required for the vehicle to reach the target temperature in the vehicle from the current temperature in the vehicle is determined according to the current ambient temperature.
Step S3: and controlling an air conditioning system of the vehicle according to the current battery power, the first battery power consumption and the second battery power consumption. And analyzing the relation between the current battery power and the first battery power consumption required for completing the target path and the second battery power consumption required for reaching the target temperature in the vehicle, if the current battery power can meet the required first battery power consumption and second battery power consumption, and then correspondingly adjusting the operating power of the air conditioning system according to the judgment result.

That is, under the normal operation condition, the current battery power cannot satisfy the first battery power consumption and the second battery power consumption at the same time, that is, the vehicle cannot walk the target path under the condition that the temperature in the vehicle reaches the target temperature in the vehicle during the normal operation of the air conditioning system, the accessory of the air conditioning system needs to be controlled to perform power reduction operation, so that the second battery power consumption is reduced, correspondingly, the saved power is used for supporting the driving of the vehicle, so that the current remaining power satisfies the first battery power consumption, the driving range of the vehicle is improved, and the vehicle is guaranteed to run the target path.
Further, in one embodiment of the present invention, the method further comprises: judging whether an air conditioner priority operation instruction sent by a driver is received; if so, the temperature threshold for cooling the battery is increased or the heating threshold for the battery is decreased until the target temperature in the vehicle is reached. In other words, when receiving the air conditioner priority operation instruction sent by the driver, which indicates that the driver wants to preferentially ensure the comfort level in the vehicle, the temperature threshold of the battery cooling is increased or the heating threshold of the battery is reduced, so that the electric quantity consumed by the battery thermal management is reduced, the operation power of the air conditioning system is ensured as far as possible until the target temperature in the vehicle is reached, and the comfort level in the vehicle is ensured.
In one embodiment of the present invention, controlling an air conditioning system of a vehicle according to a current battery power level, a first battery power consumption, and a second battery power consumption further includes: and if the current battery power can simultaneously meet the first battery power consumption and the second battery power consumption, controlling the air conditioning system to normally operate until the target temperature in the vehicle is reached. That is to say, under the normal operating condition, the current battery power can satisfy first battery power consumption and second battery power consumption simultaneously, and the vehicle also can walk the target route smoothly under the condition that the temperature reaches the target temperature in the car when air conditioning system normally operates promptly under the normal running driving in the car, says that the battery power is sufficient, then keeps the vehicle to normally travel, and control air conditioning system normal operating simultaneously can.
In summary, in the method according to the embodiment of the present invention, by obtaining the destination and the route plan determined by the driver, when it is determined that the driving range of the vehicle cannot meet the driving requirement of the driver, the driving range is increased by sacrificing part of the comfort of the vehicle (for example, the air conditioning system operates to reduce the power to realize the ambient temperature control in the cabin), so as to ensure the driving performance of the vehicle as much as possible.
According to the control method of the vehicle, the power consumption required by the target path and the power consumption required by the target temperature in the vehicle are calculated according to the target path selected by the driver and the target temperature in the vehicle, and then the air conditioning system of the vehicle is reasonably controlled by comparing and analyzing the current battery electric quantity according to the requirements, so that the electric energy consumption of the vehicle is more reasonably distributed, the energy consumption of the whole vehicle is effectively reduced, the driving range is prolonged, and the driving performance of the vehicle is improved.
