Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A vehicle reservation management system, a vehicle reservation system, and a vehicle reservation management method according to embodiments of the invention will be described below with reference to the drawings.

FIG. 2 is a block schematic diagram of a vehicle reservation management system according to an embodiment of the present invention.

As shown in fig. 2, the vehicle reservation management system of the embodiment of the present invention may include: the system comprises a temperature adjusting device 10, an in-vehicle intelligent terminal 20 and a thermal management controller 30.

The temperature adjustment device 10 is used to adjust the temperature. The vehicle-mounted intelligent terminal 20 is used for responding to the vehicle reserved use request to obtain the current residual capacity of the power battery and determining the allowable consumption capacity according to the current residual capacity. The thermal management controller 30 is configured to obtain an ambient temperature, determine a temperature control mode according to the ambient temperature, and control the temperature adjustment device 10 according to the temperature control mode, the ambient temperature, and an allowable power consumption amount. The temperature control mode may include a scheduled heating control mode and a scheduled cooling control mode, among others.

Specifically, a user reserves the vehicle service time through a mobile phone client, and sends a reservation request to a background service platform through the mobile internet, and the background service platform locates the user vehicle and sends the request to a vehicle-mounted service terminal T-BOX (vehicle-mounted intelligent terminal 20). The vehicle-mounted intelligent terminal 20 obtains the current residual capacity of the power battery, and receives the vehicle reserved use information set by the user through the background server to determine the allowable consumption capacity. The thermal management controller 30 determines whether heating or cooling is needed currently according to the current environment temperature, and controls the temperature adjusting device 10 to adjust the temperature of the power battery according to the current environment and the allowable consumed electric quantity.

By separately introducing the thermal management controller 30 as a core unit of battery thermal management control, the BMS is no longer responsible for the thermal management function of the battery, and only reads signals such as battery temperature and the like and transmits the signals to the bus to specifically heat or cool the battery, and the thermal management controller 30 comprehensively judges whether the battery performs heating or cooling according to information such as user requirements, current environment temperature conditions, reserved vehicle use time, a battery thermal insulation and cooling curve, current battery remaining capacity and the like.

It should be noted that the thermal management controller 30 does not have to be arranged as a separate component, but may be integrated in the BMS as a separate processor, but the thermal management functions are separated from the conventional BMS chip. As shown in fig. 3, a user performs information exchange with a backend server through a 4G/5G Network via a mobile phone client, the backend server performs information interaction with a T-BOX (vehicle-mounted intelligent terminal 20) of a vehicle terminal through a dedicated line, the controllers of the vehicle perform information interaction, a CAN (Controller Area Network) bus is used, thermal management control and signal communication and control execution between the BMS and a battery are used, and hard line connection is used.

Based on the signal network, in a special environment (extremely cold or extremely hot environment), when the vehicle is parked in a non-charging state for a short time, intelligent control logic of a temperature field of the vehicle is reserved for use. In the environment, the vehicle is not supported by an external power supply, but the battery of the vehicle has a proper discharging temperature at the time of reserving use of the vehicle, the vehicle has to use the electric quantity carried by the vehicle to control a temperature field, and in the process, the used electric quantity is used for heating and cooling, so that the objective requirement of a user on the driving range can be met, the user does not need to wait for heating or cooling of the battery when using the vehicle, and the battery can be prevented from being discharged at an overhigh or overlow temperature to cause damage.

According to one embodiment of the invention, the in-vehicle intelligent terminal 20 is used for acquiring the current residual capacity of the power battery in response to the vehicle reserved use request when determining the consumption permission capacity, determining the vehicle reserved use capacity according to the vehicle reserved use request, and determining the capacity difference between the current residual capacity and the vehicle reserved use capacity as the consumption permission capacity.

Specifically, the T-BOM (on-board intelligent terminal 20) receives a vehicle reservation use request and the current remaining power fed back by the user, determines the vehicle reservation use power, and calculates the allowed power consumption by subtracting the current remaining power, and sends the calculated allowed power consumption to the thermal management controller 30.

According to an embodiment of the present invention, the in-vehicle intelligent terminal 20 is specifically configured to determine a reserved usage mileage of the vehicle according to the reserved usage request, calculate a reserved usage electric quantity of the vehicle according to the reserved usage mileage, and determine an electric quantity difference between the current remaining electric quantity and the reserved usage electric quantity of the vehicle as the allowable consumption electric quantity.

Specifically, the T-BOX (vehicle-mounted intelligent terminal 20) reads the current remaining driving range through the entire vehicle CAN network, and the current remaining driving range is obtained by reading the current remaining electric quantity of the power battery by the BMS, sending the current remaining electric quantity to the instrument and carrying out fuzzy calculation by the instrument.

The T-BOM (vehicle-mounted intelligent terminal 20) determines the reserved use driving range of the vehicle after receiving the reserved use request (the reserved driving range) fed back by the user, takes the difference value between the current remaining driving range and the reserved use driving range of the vehicle as the allowable reduction driving range, converts the allowable reduction driving range into the allowable consumption electric quantity according to fuzzy calculation by the meter, and transmits the allowable reduction driving range to the vehicle-mounted intelligent terminal 20, and the vehicle-mounted intelligent terminal 20 transmits the information to the thermal management controller 30.

It should be noted that, the reason why the information interaction is performed with the user by using the index of the current remaining driving range is that the user needs to more intuitively read the range of the vehicle next time than the electric quantity, and can give more accurate allowable electric quantity (allowable consumed electric quantity) for use.

According to one embodiment of the present invention, thermal management controller 30, when determining the temperature control mode based on the ambient temperature, is configured to enter the scheduled heating control mode when the ambient temperature is below a preset temperature range or enter the scheduled cooling control mode when the ambient temperature is above the preset temperature range. The preset temperature range can be calibrated according to actual conditions. The heating includes heat preservation, and the essence of the heat preservation is heating.

Specifically, the thermal management controller 30 reads and sends an outdoor ambient temperature signal to the bus according to the air conditioner control, and determines whether the current vehicle is in an environment that requires cooling or heat preservation (heating), or neither heat preservation nor cooling is required. When the current environment temperature is in a normal temperature range [ T1, T2], the current environment is a non-limit environment, and the user can directly wait for using the vehicle without heat preservation or cooling; when the current environment temperature is lower than the interval (namely the current environment is less than T1), entering a reserved heating control mode; when the current ambient temperature is higher than the interval (i.e., the current ambient temperature is higher than T2), the scheduled cooling control mode needs to be entered.

According to an embodiment of the present invention, the thermal management controller 30, when controlling the temperature adjustment device according to the temperature control mode, the ambient temperature, and the allowable power consumption amount, is configured to calculate a maximum temperature keeping time according to the ambient temperature and the allowable power consumption amount in the reserved heating control mode, and control the temperature adjustment device to keep the temperature when the maximum temperature keeping time is greater than or equal to a temperature keeping required time, which is a time difference between a current time and a reserved use start time of the vehicle; or, in the reserved cooling control mode, when the power battery consumption capacity in the first preset time is judged to be smaller than or equal to the allowable consumption capacity according to the environment temperature, the temperature adjusting device is controlled to be started at the first preset time before the reserved use time of the vehicle. The first preset time may be calibrated according to an actual situation, for example, the first preset time may be 20 min.

According to an embodiment of the present invention, the thermal management controller 30 is further configured to, in the scheduled heating control mode, obtain a cooling rate curve of the power battery at an ambient temperature, predict whether the temperature of the power battery will be lower than the discharging temperature range when the scheduled service time of the vehicle is reached according to the cooling rate curve, and control the temperature adjustment device 10 to heat the power battery when it is predicted that the temperature of the power battery will be lower than the discharging temperature range; or, in the reserved cooling control mode, acquiring a temperature-rising rate curve of the power battery at the ambient temperature, pre-judging whether the temperature of the power battery is higher than the discharging temperature range when the reserved service time of the vehicle is reached according to the temperature-rising rate curve, and controlling the temperature regulating device 10 to cool the power battery when the temperature of the power battery is pre-judged to be higher than the discharging temperature range. The discharge temperature range can be calibrated according to actual conditions.

According to an embodiment of the present invention, the thermal management controller 30 is further configured to send a prompt for adjusting the reserved usage information of the vehicle when the maximum insulation time is less than the insulation demand time in the reserved heating control mode, or send a prompt for adjusting the reserved usage information of the vehicle when the power battery consumes more power than the allowable power consumption for the first preset time in the reserved cooling control mode.

Specifically, the workflow of the scheduled heating control mode is as follows: firstly, the thermal management controller 30 calculates the longest heat preservation time according to the allowable power consumption and the current ambient temperature, then, determines whether the longest heat preservation time is greater than or equal to the heat preservation required time (the reservation time of the user), and when the longest heat preservation time is greater than or equal to the heat preservation required time, it indicates that the allowable power consumption can meet the heat preservation requirement of the user, and at this time, the thermal management controller 30 controls the temperature adjustment device to perform the heat preservation operation until the user uses the vehicle or the reservation time of the user. When the longest heat preservation time is less than the heat preservation requirement time, it indicates that the allowed consumed electric quantity cannot meet the heat preservation requirement of the user, and at this time, the thermal management controller 30 sends a message to the mobile phone end of the user through the vehicle-mounted intelligent terminal 20(T-BOX) to notify the user that the vehicle is not enough to preserve heat to the reserved time under the condition that the remaining driving range is required to be preserved, and whether the remaining driving range is reduced or the remaining driving range is performed according to the current requirement is not required to be preserved to the reserved time. If the user feeds back to continue executing the current instruction or no feedback is given, the thermal management controller 30 starts to execute the heat preservation operation until the user uses the vehicle or the user reserves time; if the user chooses to reduce the driving range, the vehicle-mounted intelligent terminal 20(T-BOX) recalculates the driving range according to the reduced driving range until the allowed power consumption is enough to meet the heat preservation requirement.

In the entire heating control mode, the battery heating function does not need to be turned on all the time, the thermal management controller 30 will call the beginning of the vehicle development, and determine whether the battery temperature will be reduced to the minimum discharge temperature TL before the time when the user reserves to use the vehicle comes according to the cooling rate curve by calibrating the cooling rate curve of the power battery preset in the system at the current ambient temperature. If the temperature is lower than TL, the power battery is heated (the temperature reduction rate of the battery pack is adjusted) by intermittently starting the temperature adjusting device 10; otherwise, the temperature adjusting device does not need to be started.

The working flow of the reserved cooling control mode is as follows: generally, after the thermostat 10 is turned on for a first preset time (e.g. 20min), it is sufficient to lower the temperature of the power battery to the allowable use temperature, so that the thermal management controller 30 only needs to determine the magnitude relationship between the consumed power amount and the allowable consumed power amount for the first preset time (e.g. 20 min). When the consumed electric quantity of the power battery in the first preset time is less than or equal to the allowable consumed electric quantity, the temperature adjusting device 10 is controlled to be started 20min before the reserved use time of the vehicle, wherein if the vehicle is used in the period, the battery cooling reservation is quitted. When the consumed electric quantity of the power battery in the first preset time is larger than the allowable consumed electric quantity, informing the user that the vehicle is not enough to cool the battery before the reserved time, reduce the residual driving range or confirm to cancel the reserved cooling under the condition of requiring the reserved driving range. If the user feeds back to cancel the reservation or does not feed any feedback, giving up the reservation and waiting until the user uses the vehicle; if the user chooses to reduce the driving range, the vehicle-mounted intelligent terminal 20(T-BOX) recalculates the driving range according to the reduced driving range until the allowed power consumption is enough to meet the heat preservation requirement.

In order to reduce the power consumption, in many cases, the power battery does not need to be cooled to the maximum extent, and the thermal management controller 30 may calibrate a temperature rise rate curve of the power battery preset in the system under the current ambient temperature and the sunshine condition according to the beginning of the development, and determine whether the battery temperature rises to the highest temperature TH suitable for discharging before the time when the user reserves to use the vehicle comes according to the temperature rise rate curve. If the temperature is higher than TH, the power battery is cooled (the temperature rise rate of the battery pack is adjusted) by intermittently starting the temperature adjusting device 10; otherwise, the temperature adjusting device does not need to be started.

According to one embodiment of the present invention, the temperature adjusting device 20 may include a battery temperature adjusting device for adjusting the temperature of the power battery of the vehicle.

According to an embodiment of the present invention, the temperature adjustment device 10 may include an in-vehicle temperature adjustment device, and the thermal management controller 30 is specifically configured to control the battery temperature adjustment device to keep the power battery of the vehicle warm when controlling the temperature adjustment device 10 to keep the temperature, and to control the in-vehicle temperature adjustment device to heat when the second preset time is away from the reserved service time of the vehicle. That is, in the heating control mode, the battery temperature adjusting device keeps warm for the power battery, and when the time before the reserved use time is reached, the in-vehicle temperature adjusting device heats the power battery.

According to one embodiment of the invention, the use habits of the user are actively learned through the AI chip, the use habits of the user are gradually known through analysis of the use habits of the user and comparison with big data, the times of inquiring the user can be reduced according to the learning in a period of time, and even the intelligent reservation heating function can be automatically started according to the use habits of the user, so that the user can gradually forget the influence of the temperature on the battery, even forget that the battery has already finished the reservation temperature control function before using the vehicle, and the user experience is greatly improved.

As a specific example, as shown in fig. 4, the flow of the vehicle reservation management method may include the steps of:
