[0017] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0019] like Figure 1 A method for reducing vehicle use cost is shown, comprising the following steps: S100: when the vehicle is in a driving state and the first preset mode is in an on state, obtaining first preset information, determining user needs according to the first preset information; based on the user needs, determining a target driving configuration and a target vehicle cost reduction plan that match the user needs according to a first preset rule; requesting to adjust the driving configuration of the vehicle to the target driving configuration, and requesting to execute the target vehicle cost reduction plan in the vehicle; S200: When the vehicle needs to be charged and the first preset mode is in the on state, obtain the second preset information, and determine the charging demand of the vehicle according to the second preset information; based on the charging demand, determine one or more target charging plans that can meet the charging demand and have the lowest charging cost according to the second preset rules; request to push one or more target charging plans to the user.

[0020] By adopting the above technical solution, the vehicle electricity usage scenario can effectively reduce the vehicle cost on the basis of meeting the user's needs. Moreover, by ensuring that the user's needs are met, the target vehicle cost reduction solution can be implemented in more electricity usage scenarios, and the user can effectively control the vehicle cost in more actual vehicle usage scenarios. In the vehicle charging scenario, the economic charging solution can be pushed to the user, which helps to reduce the vehicle cost and effectively control the vehicle cost in more vehicle usage scenarios.

[0021] In some embodiments, obtaining the first preset information, and determining the user demand according to the first preset information comprises the following steps: obtaining the planned driving route of the vehicle, the road condition information of the planned driving route, and the driving habits of the driver, and determining the driving demand according to the planned driving route, the road condition information, and the driving habits; Based on user needs, determining a target driving configuration and a target vehicle cost reduction plan that match the user needs according to a first preset rule includes the following steps: based on driving needs, determining a target driving mode and a target energy recovery mode that match the driving needs according to a first preset rule.

[0022] By adopting the above technical solution, the driving needs are first determined, and then the matching target driving mode and target energy recovery mode are determined according to the driving needs, which can better meet the user's driving needs.

[0023] In specific implementation, the acquired planned driving route, road condition information and driving habits can be used as driving requirements, and the vehicle's VCU controller matches the target driving mode and target energy recovery mode that best meet the driving requirements based on the acquired planned driving route, road condition information and driving habits according to the driving requirement rule data pre-stored in the database. In specific implementation, the driving requirement rule data can be a pre-trained machine learning model or a pre-defined mapping relationship table.

[0024] The vehicle's VCU controller sends the corresponding request instructions to the corresponding on-board controller, which can adjust the vehicle's driving mode and energy recovery mode to the target driving mode and target energy recovery mode, that is, realize the switching of the driving mode and energy recovery mode, so that the vehicle's driving mode and energy recovery mode match the user's driving needs.

[0025] That is to say, in the specific implementation, the first preset information includes the planned driving route of the vehicle, the road condition information of the planned driving route and the driver's driving habits, the driving configuration includes the driving mode and the energy recovery mode, and the target driving configuration includes the target driving mode and the target energy recovery mode.

[0026] In some embodiments, obtaining the first preset information and determining the user demand according to the first preset information comprises the following steps: obtaining a planned driving route of the vehicle and the current remaining power of the vehicle, and based on the planned driving route and the current remaining power, calculating the energy consumption demand corresponding to the planned driving route according to the historical energy consumption information of the vehicle; Based on user needs, determining a target driving configuration and a target vehicle cost reduction plan that matches the user needs according to a first preset rule includes the following steps: based on energy consumption needs, determining a target engine start-stop battery power threshold and a target engine power generation power that can meet the energy consumption needs and are most economical according to the first preset rule.

[0027] By adopting the above technical solution, by adjusting the battery power threshold for engine start-stop and the power generated by the engine, the vehicle can use the power of the power battery as much as possible, which can achieve more electricity and less oil consumption, and help reduce vehicle use costs. Increasing the battery power threshold for engine start-stop and reducing the power generated by the engine can both help the vehicle achieve more electricity and less oil consumption.

[0028] In specific implementation, the vehicle's VCU controller calculates the energy consumption demand based on the vehicle's planned driving route, the vehicle's current remaining power and the vehicle's historical energy consumption information. The vehicle's VCU controller matches the target engine start-stop battery power threshold and target engine power generation power that meet the energy consumption demand and are most economical based on the energy consumption demand rule data pre-stored in the database. The energy consumption demand rule data can be a pre-trained machine learning model or a predefined mapping relationship table.

[0029] The vehicle's VCU controller sends the corresponding request instructions to the corresponding on-board controller, which can adjust the engine start-stop battery power threshold and engine power generation power, thereby achieving more electricity and less oil consumption.

[0030] That is to say, in the specific implementation, the first preset information includes the planned driving route of the vehicle and the current remaining power of the vehicle, and the vehicle cost reduction plan includes adjusting the engine start-stop battery power threshold and adjusting the engine power generation power.

[0031] In some embodiments, obtaining first preset information, and determining user requirements according to the first preset information includes the following steps: obtaining an ambient temperature, a battery temperature, a set temperature of the passenger compartment, and a planned driving route of the vehicle, and determining thermal management requirements according to the ambient temperature, the battery temperature, the set temperature of the passenger compartment, and the planned driving route; Based on user needs, determining a target driving configuration and a target vehicle cost reduction plan that matches the user needs according to a first preset rule includes the following steps: based on thermal management needs, determining a target thermal management plan that can meet the thermal management needs and is the most economical according to the first preset rule.

[0032] By adopting the above technical solution and adjusting the target thermal management solution, the energy consumption of the vehicle can be reduced, which helps to reduce the cost of using the vehicle.

[0033] In the specific implementation, the vehicle's VCU controller matches the target battery temperature range and the target passenger compartment temperature range based on the vehicle's ambient temperature, battery temperature, passenger compartment set temperature and planned driving route according to the thermal management requirement rule data pre-stored in the database. The target battery temperature range and the target passenger compartment temperature range are the thermal management requirements, which can be a pre-trained machine learning model or a predefined mapping relationship table.

[0034] Furthermore, the vehicle's VCU controller can match a reasonable allocation of thermal management power based on thermal management requirements and thermal management rule data pre-stored in the database. The thermal management rule data can be a pre-trained machine learning model or a pre-defined mapping relationship table. The use of a reasonable allocation of thermal management power can ensure the comfort of the passenger compartment and battery cooling or heating, ensure that the battery is used within the optimal temperature range, and help reduce energy consumption.

[0035] The vehicle's VCU controller sends the corresponding request instructions to the corresponding on-board controller, which can achieve reasonable allocation of thermal management power.

[0036] That is to say, in the specific implementation, the first preset information includes the vehicle's ambient temperature, battery temperature, passenger compartment set temperature and planned driving route, and the vehicle cost reduction plan includes the reasonable allocation of thermal management power.

[0037] In some embodiments, obtaining first preset information, and determining user needs according to the first preset information includes the following steps: obtaining intelligent driving usage information and vehicle-mounted electrical appliance usage information of the vehicle, and determining intelligent driving usage needs and vehicle-mounted electrical appliance usage needs according to the intelligent driving usage information and the vehicle-mounted electrical appliance usage information; Based on user needs, determining a target driving configuration and a target vehicle cost reduction plan that match the user needs according to a first preset rule includes the following steps: Based on the intelligent driving usage needs and the vehicle electrical appliance usage needs, determining a target intelligent driving management plan and a target vehicle electrical appliance management plan that can meet the intelligent driving usage needs and the vehicle electrical appliance usage needs and are the most economical according to the first preset rule.

[0038] By adopting the above-mentioned technical solutions and managing the energy consumption of intelligent driving and vehicle electrical appliances, it is possible to reduce unnecessary energy output, reduce energy consumption, ensure that the vehicle uses less electricity to travel the same distance, and help reduce vehicle use costs.

[0039] In specific implementation, the probability of using smart driving and the probability of using onboard electrical appliances can be analyzed by analyzing the use information of smart driving and the use information of onboard electrical appliances, and the probability can represent the use demand of smart driving and the use demand of onboard electrical appliances. In specific implementation, a pre-trained machine learning model can be used to analyze the probability of using smart driving and the probability of using onboard electrical appliances.

[0040] After analyzing the probability of using smart driving and the probability of using vehicle electrical appliances, the target smart driving management scheme and target vehicle electrical appliance management scheme of the corresponding level can be determined according to the size level of the probability. For example, when the probability of using smart driving is less than the preset first probability threshold, the vehicle's VCU controller can control the shutdown of the vehicle's smart driving function. For another example, when the probability of using vehicle electrical appliances is less than the second probability threshold, the vehicle's VCU controller can control the reduction of the power consumption of some vehicle electrical appliances. When the probability of using vehicle electrical appliances is less than the third probability threshold, the vehicle's VCU controller can control the shutdown of some vehicle electrical appliances. The vehicle's VCU controller sends the corresponding request instruction to the corresponding controller to perform the above operations.

[0041] While executing the target intelligent driving management plan and the target vehicle electrical appliance management plan, the user can be reminded, for example, by notifying the user through text or voice that the intelligent driving function has been turned off.

[0042] That is to say, in the specific implementation, the first preset information includes the vehicle's intelligent driving usage information and on-board electrical appliance usage information, and the vehicle cost reduction plan includes a target adjustment intelligent driving usage plan and a target on-board electrical appliance usage plan.

[0043] In specific implementation, the intelligent driving usage information may include the activation frequency and usage duration of the autonomous driving function. The vehicle electrical appliance usage information may include the activation frequency and usage duration of the vehicle electrical appliances, such as the activation frequency and usage duration of the DC-DC converter.

[0044] like Figure 2 As shown, as a specific example, in an electricity usage scenario, a method for reducing vehicle use costs includes the following steps: S101: When the vehicle is in a driving state and the first preset mode is in an on state, first preset information is obtained.

[0045] S102: Determine driving demand based on the planned driving route of the vehicle in the first preset information, the road condition information of the planned driving route and the driving habits of the driver; based on the driving demand, determine a target driving mode and a target energy recovery mode that match the driving demand according to the first preset rule; request to adjust the driving mode and the energy recovery mode of the vehicle to the target driving mode and the target energy recovery mode.

[0046] S103: Based on the planned driving route of the vehicle in the first preset information and the current remaining power of the vehicle, calculate the energy consumption demand corresponding to the planned driving route according to the historical energy consumption information of the vehicle; based on the energy consumption demand, determine the most economical target engine start-stop battery power threshold and target engine power generation power that can meet the energy consumption demand according to the first preset rule; request to execute the target engine start-stop battery power threshold and target engine power generation power in the vehicle.

[0047] S104: Determine the thermal management requirements based on the vehicle's ambient temperature, battery temperature, passenger compartment set temperature and planned driving route in the first preset information; based on the thermal management requirements, determine the most economical target thermal management solution that can meet the thermal management requirements according to the first preset rules; and request execution of the target thermal management solution in the vehicle.

[0048] S105: Based on the intelligent driving usage information and the vehicle electrical appliance usage information in the first preset information, determine the intelligent driving usage requirements and the vehicle electrical appliance usage requirements; based on the intelligent driving usage requirements and the vehicle electrical appliance usage requirements, determine the most economical target intelligent driving management plan and target vehicle electrical appliance management plan that can meet the intelligent driving usage requirements and the vehicle electrical appliance usage requirements according to the first preset rules; request to execute the target intelligent driving management plan and the target vehicle electrical appliance management plan in the vehicle.

[0049] By adopting the above technical solution, in the electricity usage scenario, by adjusting the driving configuration and executing the target vehicle cost reduction plan, it is possible to more effectively reduce the vehicle cost in more actual vehicle usage scenarios while meeting user needs.

[0050] In some embodiments, based on the charging demand, determining one or more target charging schemes that can meet the charging demand and have the lowest charging cost according to a second preset rule includes the following steps: based on the charging demand, determining one or more target charging points that can meet the charging demand and have the lowest charging cost according to a second preset rule.

[0051] In specific implementation, the vehicle's VCU controller can estimate the vehicle's pure electric driving distance based on the vehicle's positioning and the remaining battery power, and push the location of the charging station within the coverage range of the pure electric driving distance to the user, which can remind the user to charge immediately and help achieve more electricity and less oil consumption.

[0052] In some embodiments, the method for reducing vehicle usage costs also includes the following steps: obtaining a target charging point selected by a user, calculating the most economical target charging method and target charging time period based on the charging method of the target charging point selected by the user and the charging costs for each time period, and requesting that the target charging method and target charging time period be pushed to the user.

[0053] In specific implementation, after the user selects the location of the charging station, the vehicle's VCU controller can calculate the optimal charging method and time period based on the charging method and charging time period costs, and send them to the corresponding controller based on charging time, cost, energy consumption conditions, etc., and push them to the user for selection. The user chooses the charging method and time period according to their own needs, which helps reduce charging costs and ensures that users charge the same amount of electricity with the least money.

[0054] More specifically, in the actual implementation, the vehicle's VCU controller can score the charging piles according to the preset scoring rules based on the distance, charging method, charging cost and other information of the charging piles. The vehicle's VCU controller compares the weighted scores of each charging pile, screens out the most economical charging pile location, and sends it to the corresponding controller, which is then pushed to the user.

[0055] In some embodiments, the method for reducing vehicle use costs further includes the following steps: when the vehicle is in a driving state, in response to receiving a user's request to start the first preset mode, start the first preset mode. In the power usage scenario, the first preset mode is started under the control of the user, which can meet the user's different driving experience requirements.

[0056] In some embodiments, the method for reducing vehicle use costs further includes the following steps: when it is determined that the vehicle needs to be charged, the first preset mode is turned on. In the charging scenario, the VCU controller of the vehicle automatically turns on the first preset mode, which can remind the user to charge more promptly.

[0057] In a specific implementation, the current remaining power of the vehicle may be compared with a preset power threshold. When the current remaining power of the vehicle is less than the preset power threshold, it may be determined that the vehicle needs to be charged.

[0058] In some embodiments, the method for reducing vehicle use costs further includes the following steps: When user needs change, the target driving configuration and target vehicle cost reduction plan are updated; a request is made to switch the vehicle's driving configuration to the updated target driving configuration, and a request is made to execute the updated target vehicle cost reduction plan in the vehicle.
