Fig. 1 is an application scenario diagram of a parking time acquisition method of a vehicle according to an exemplary embodiment of the present application, wherein the vehicle is networked through a TBOX (Telematics-BOX) and then acquires a positioning time through a GPS (Global Positioning System ) time system as shown in fig. 1; and after the vehicle is powered on at low voltage, uploading the time of the real-time clock by the TBOX, acquiring a time signal of the positioning time system through connecting with the Internet, updating by taking the time of the positioning time system as an effective value, and setting the updating period to be 1S for updating once. When the situation of feeding the storage battery, disconnecting low-voltage connection, poor pressure contact or GPS signal difference occurs in the whole vehicle, delay updating can occur in the time of TBOX transmission. Therefore, the power-on time and the power-off time are recorded through the BMS battery management system in the vehicle, and when the conditions of feeding of the storage battery, disconnection of low-voltage connection, poor voltage contact or GPS signal difference and the like occur in the whole vehicle, the parking time is calculated by using the power-on time and the power-off time.

s210, acquiring a positioning time signal and a time validity signal sent by a positioning time system, and acquiring a last power-on time signal and a last power-off time signal sent by a battery management system;
in this embodiment, when the existing positioning time system generates the positioning time signal, a time validity signal for indicating whether the positioning time signal is reliable is generated at the same time, where the time validity signal includes a valid state and an invalid state; when the time validity signal is in a valid state, the corresponding positioning time signal is indicated to be reliable; when the time validity signal is in an invalid state, the corresponding positioning time signal is unreliable, and time delay can exist; the last power-on time signal and the last power-off time signal are generated by a real-time clock in the vehicle, and each time the vehicle is powered on or powered off at low voltage, a clock signal is recorded by the real-time clock; the last power-on time signal is a clock signal recorded when the vehicle is powered on last time, and the last power-off time signal is a clock signal recorded when the vehicle is powered off last time before parking.

in step S220, when the time validity signal is in an invalid state, it is indicated that there may be a delay in the positioning time signal, and the positioning time signal cannot be used to perform the calculation of the electric quantity state and the calculation of the battery life; at the moment, a timer in the vehicle starts a timing mode, and continuously receives a positioning time signal and a time validity signal; when the time validity signal in the valid state is received in the preset time period, the situation that the vehicle is fed from the storage battery, the low-voltage connection is disconnected, the low-voltage connection is poor or the GPS signal is poor is indicated, the local clock can work normally, and the last power-on time signal is determined to be reliable if the corresponding positioning time signal is consistent with the preset state.
S230, calculating a time acquisition difference value of the last power-on time signal and the last power-off time signal according to a comparison result, and taking the time acquisition difference value as parking time;

s310, when the time validity signal is always in an invalid state within a preset time period, judging that the last power-on time signal is unavailable;
in step S310, the time validity signal is always in an invalid state within a preset time period, which indicates that the vehicle fails to power up normally, and the working state of the local clock is uncertain, so as to determine that the last power-up time signal is not available.
S320, when the last power-on time signal is not available, the value of the parking time is reset to zero.
In step S320, when it is determined that the last power-on time signal is not available, the parking time cannot be calculated by the last power-on time signal, so that the parking time is directly zeroed.
In an embodiment of the present application, the process of comparing the state of the received positioning time signal with the preset state may include steps S410 to S420, which are described in detail as follows:
s410, comparing the length of the positioning time signal with a preset length range, and comparing the acquisition time of the positioning time signal with the acquisition time of the last power-down time signal;

In step S510, when the length of the positioning time signal is within the preset length range and the acquisition time of the positioning time signal is later than the acquisition time of the last power-on time signal, it is indicated that the signal format of the positioning time signal conforms to the predefined format and is the positioning time signal acquired last time, so that it is determined that the last power-on signal is available. Specifically, the predefined format may further include information such as position and accuracy.
In an embodiment of the present application, the process of taking the time acquisition difference value as the parking time may further include step S610, which is described in detail below:
and S610, carrying out electric quantity state management based on the parking time, and/or carrying out battery life management based on the parking time.

When the positioning time signal is inaccurate, whether the last power-on time signal is accurate is judged, and when the last power-on time signal is accurate, the parking time is calculated by utilizing the last power-on time signal and the last power-off signal, so that the accurate parking time can be obtained when the vehicle is in low voltage or the positioning signal is weak; therefore, the technical problems that the parking time is inaccurate and the running speed and the accuracy of the calculation result of the battery management system are affected are solved.
