Problems solved by technology

However, the existing solutions do not consider the economy of battery replacement or refueling when performing energy replenishment, nor do they make reasonable battery capacity recommendations based on the driver’s historical driving data, especially prompting the user to quickly replace the battery during short-distance driving When replacing, it does not specify how to choose a matching quick-change battery to ensure better vehicle convenience and economy

Embodiment 1

[0073] figure 2 A schematic flowchart of a method for determining a battery swapping strategy for a battery swapping hybrid electric vehicle according to another embodiment (Embodiment 1) of the present invention is shown. see figure 2 As shown, the method for determining a battery swapping strategy in this embodiment includes the following steps S202 to S216.

[0074] Step S202, determining the target driving condition of the vehicle.

[0075] In Embodiment 1, it is determined that the target driving condition of the vehicle is a long-distance high-speed driving condition. In practical applications, this method can be started to determine the power exchange strategy when the vehicle is already in long-distance high-speed driving (that is, when the vehicle has started long-distance high-speed driving). The method is started to determine the power exchange strategy before the vehicle is about to travel at a long distance and at a high speed.

Embodiment 2

[0097] image 3 A schematic flowchart of a method for determining a battery swap strategy of a battery swap type hybrid electric vehicle according to yet another embodiment (embodiment 2) of the present invention is shown. see image 3 As shown, the method for determining a battery replacement strategy in this embodiment includes the following steps S302 to S318.

[0098] Step S302, determining the target driving condition of the vehicle.

[0099] In Embodiment 2, it is determined that the target driving condition of the vehicle is an urban commuting condition. In practical applications, the method can be started to determine the battery replacement strategy when the vehicle is already in the urban commuting condition (that is, when the vehicle has started daily commuting), for example, it can be started when the vehicle arrives at the battery replacement station during urban commuting.

[0100] Determining the target driving condition can be carried out in a variety of way...

Abstract

The invention provides a battery replacement strategy determination method of a battery replacement type hybrid power vehicle, a vehicle control unit and the battery replacement type hybrid power vehicle. The method comprises the following steps: determining a target driving condition of a vehicle, wherein the target driving condition is a current driving condition or a to-be-operated driving condition of the vehicle; according to the target driving working condition, selectively obtaining the state information of the vehicle, the energy price information and the required information in the use habit information of the user; and based on the acquired information, determining a target battery replacement strategy according to a battery replacement strategy determination rule corresponding to the target driving condition, and recommending the target battery replacement strategy to the user. According to the method, the use convenience of the vehicle is guaranteed, meanwhile, the use economy of the vehicle is guaranteed, and the vehicle use cost of a user (a driver) under different driving working conditions is reduced.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, in particular to a method for determining a battery swap strategy for a battery swap hybrid vehicle, a vehicle controller and a battery swap hybrid vehicle. Background technique [0002] Hybrid technology is a key technology to achieve energy saving and emission reduction of vehicles. Plug-in hybrid vehicles are a new energy vehicle between pure electric vehicles and fuel vehicles. They can not only achieve pure electric, zero-emission driving, but also increase the vehicle's driving range through hybrid mode. In low- and medium-speed conditions, pure electric driving of plug-in hybrid vehicles can significantly reduce vehicle operating costs. However, fixed-capacity battery packs cannot meet the actual needs of users with different commuting distances. In long-distance high-speed conditions, the plug-in hybrid vehicle is basically in the traditional fuel mode, and the large-capacity ba...
