CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to a Chinese patent application filed with the Chinese Patent Office on October 26, 2022, with application number 202211320256.1 and invention name “Extended-range electric vehicle control method, device and vehicle”, the entire contents of which are incorporated by reference in this application.

Technical Field

The present invention relates to the field of vehicle control technology, and in particular to a control method, device, vehicle, electronic equipment and storage medium for an extended-range electric vehicle.

Background technique

In the related technology, the vehicle pre-stores the air-conditioning operating condition data and the remaining battery power. The air-conditioning operating condition data includes the ambient temperature inside and outside the vehicle.

Detailed ways

Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

To this end, the present invention proposes a control method, device, vehicle, electronic equipment and storage medium for an extended-range electric vehicle.

Specifically, a range-extended electric vehicle control method, device, vehicle, electronic device, and storage medium according to an embodiment of the present invention are described below with reference to the accompanying drawings.

FIG1 is a flow chart of a range-extended electric vehicle control method according to an embodiment of the present invention. It should be noted that the range-extended electric vehicle control method according to the embodiment of the present invention can be applied to the range-extended electric vehicle control device according to the embodiment of the present invention, and the device can be configured on an electronic device or in a server. The electronic device can be a PC or a mobile terminal. The embodiment of the present invention does not limit this.

As shown in FIG1 , the extended-range electric vehicle control method includes:

S110, receiving a rest mode trigger instruction, and determining whether a rest mode start condition is met.

In an embodiment of the present invention, a trigger instruction of the rest mode may be received by a terminal device, and it may be determined whether a start condition of the rest mode is met.

The terminal device may provide a display interface, and may receive a trigger instruction for the rest mode by triggering a button in the display interface.

In the embodiment of the present invention, the determination of whether the rest mode activation condition is met can be achieved by determining whether the vehicle meets the rest mode activation condition and whether the range extender activation restriction condition is met. The specific implementation method can refer to the subsequent embodiments.

S120: When it is determined that the start condition of the rest mode is met, the vehicle is controlled to enter the rest mode.

S130, when it is determined based on the preset time that the working state of the range extender is turned on or the communication state is not connected, a reminder is issued and an exit from the rest mode is executed within the preset reminder time.

In this embodiment, the communication status "not connected" refers to the loss of communication between the HU (multimedia host) and the VBU (vehicle control unit).

In one embodiment of the present invention, after the vehicle enters the rest mode, the working status of the range extender can be monitored based on a preset time. When it is determined that the working status of the range extender is on, the rest mode is actively exited. Within the preset reminder time, if it is detected that the rest mode is not actively exited, the rest mode is automatically exited.

In another embodiment of the present invention, after the vehicle enters the rest mode, based on a preset time, when the communication status between the on-board multimedia and the on-board controller is detected to be disconnected, the rest mode is actively exited. Within the preset reminder time, if it is detected that the rest mode is not actively exited, the rest mode is automatically exited.

In order to make it easier for those skilled in the art to understand the present invention, FIG2 is a flow chart of a method for controlling an extended-range electric vehicle according to a specific embodiment of the present invention. As shown in FIG2, the method for controlling an extended-range electric vehicle includes:

S210, receiving a rest mode trigger instruction.

The triggering instruction of the rest mode may also be received by voice. For example, when a voice message "please turn on the rest mode" is received, the triggering instruction of the rest mode may be received.

Among them, when it is detected that the vehicle is not started and the user's eye state is detected by the camera, if the user's eye closure time reaches the preset eye closure time, the trigger instruction of the rest mode can be automatically triggered, and then the trigger instruction of the rest mode can be received.

Among them, when it is detected that the user's heart rate is within the resting heart rate range, the trigger instruction of the rest mode can be automatically triggered, and then the trigger instruction of the rest mode can be received.

S220: Determine whether the vehicle meets the conditions for starting the rest mode.

In an embodiment of the present invention, the vehicle can be determined to meet the rest mode activation condition by determining the battery SOC value and judging that the battery SOC value is not less than the sum of the battery SOC value when the engine is started and the first threshold.

In order to ensure the minimum power level for entering the rest mode, the first threshold is 10%.

For example, when the battery SOC value is 40% and the battery SOC value is 20% when the engine is started, it can be determined that when the battery SOC value of 40% is greater than the sum of the battery SOC values of 20% and 10% when the engine is started, it can be determined that the vehicle meets the conditions for starting the rest mode.

In one embodiment of the present invention, when it is determined that the battery SOC value is less than the sum of the battery SOC value when the engine is started and the first threshold, it is determined that the vehicle does not meet the start condition of the rest mode.

S230, determining whether the vehicle satisfies conditions for limiting the start of the range extender.

In an embodiment of the present invention, it is possible to determine whether the vehicle meets the conditions for restricting the start of the range extender by acquiring the sensor signal value in real time and according to the corresponding relationship between the sensor signal value and the start of the range extender.

For example, when the engine signal value is received, where the signal value is 02, it can be determined that the engine is in operation, and then through the corresponding relationship between the signal value 02 and the start of the range extender, it can be determined that the conditions for limiting the start of the range extender are not met. At the same time, the voice prompt "The front hatch is open, please close the front hatch"

For example, when the engine signal value is received, where the signal value is 03, the corresponding relationship between the signal value 03 and the start of the range extender can be determined, and the engine can be determined to be in a running state, and then the conditions for limiting the start of the range extender are determined not to be met. At the same time, a voice prompt "The transmitter is not shut down, please try again later" is given.

For another example, when an engine signal value is received, where the signal value is 01, it can be determined that the engine is in an off state, and then through the correspondence between the signal value 01 and the start of the range extender, it can be determined that the condition for limiting the start of the range extender is met.

S240, if yes, determine the target seat of the vehicle, and when the target seat position is adjusted to the rest mode, determine that the start condition of the rest mode is met, and control the vehicle to enter the rest mode.

In an embodiment of the present invention, when it is determined that the conditions for limiting the start of the range extender are met, the target seat of the vehicle can be determined, and the position of the target seat can be adjusted to the position of the rest mode, and then it can be determined that the start conditions of the rest mode are met to control the vehicle to enter the rest mode.

In one embodiment of the present invention, if adjusting the target seat position to the rest mode fails, a pop-up window may be displayed to remind "Failed to turn on the rest mode, do you want to try again"? If the user chooses to turn it on again, the position corresponding to the rest mode seat will be provided to the user again. If the user chooses to cancel, the rest mode will not be entered and the rest mode state will be exited.

S250, when it is determined based on the preset time that the working state of the range extender is turned on or the communication state is not connected, a reminder is issued and an exit from the rest mode is executed within the preset reminder time.

In one embodiment of the present invention, it is determined that the position of the target seat is adjusted to the position of the rest mode. Based on the preset time, the working state of the range extender can be monitored. When it is determined that the working state of the range extender is turned on, the rest mode is actively exited. Within the preset reminder time, if it is detected that the rest mode is not actively exited, the rest mode is automatically exited, and a voice prompt is given to the user that "the rest mode has been automatically exited to ensure safety due to the start of the range extender". Among them, the current position of the target seat is adjusted to a non-rest mode.

In another embodiment of the present invention, it is determined to adjust the position of the target seat to the rest mode position. Based on the preset time, when the communication status between the vehicle-mounted multimedia and the vehicle-mounted controller is detected as being disconnected, the rest mode is actively exited. Within the preset reminder time, if it is detected that the rest mode is not actively exited, the rest mode is automatically exited. At the same time, a pop-up window prompts the user that "the rest mode has been automatically exited to ensure safety due to the start of the range extender". Among them, the current position of the target seat is adjusted to a non-rest mode.

In yet another embodiment of the present invention, when there is a timed task in the rest mode, a reminder is given and the exit from the rest mode is executed within a preset reminder time, and the timed task is stopped at the same time.

According to the control method of the extended-range electric vehicle of the embodiment of the present invention, a trigger instruction of the rest mode is received, it is determined that the vehicle meets the conditions for starting the rest mode, and it is judged whether the vehicle meets the conditions for limiting the start of the range extender. If so, the target seat of the vehicle is determined, and when the target seat position is adjusted to the rest mode, it is determined that the conditions for starting the rest mode are met, and the vehicle is controlled to enter the rest mode. When it is determined based on the preset time that the working state of the range extender is turned on or the communication state is not connected, within the preset reminder time, a reminder is given and the exit from the rest mode is executed. This method can ensure that when the range extender is started, the rest mode is reminded and automatically exited, effectively preventing the situation where the range extender has been started but the rest mode has not been exited, and ensuring that the extended-range power vehicle model uses the rest mode without the intervention of the range extender, improving the accuracy of the rest mode exit time point, and improving the safety of the extended-range power vehicle model when using the rest mode, avoiding the risk of carbon monoxide poisoning.

According to the control device of the extended-range electric vehicle of the embodiment of the present invention, by receiving the trigger instruction of the rest mode and determining whether the start-up conditions of the rest mode are met; when it is determined that the start-up conditions of the rest mode are met, the vehicle is controlled to enter the rest mode; when it is determined based on the preset time that the working state of the range extender is turned on or the communication state is not connected, a reminder is given and the exit from the rest mode is executed within the preset reminder time. This ensures that when the range extender is started, a reminder is given and the rest mode is automatically exited, effectively preventing the situation where the range extender has been started but the rest mode has not been exited, and ensuring that the extended-range power vehicle model uses the rest mode without the intervention of the range extender, and improves the accuracy of the exit time point of the rest mode.

In one embodiment of the present invention, the control module 320 includes a first judgment unit, which is used to determine whether the vehicle meets the conditions for limiting the start of the range extender when the vehicle meets the conditions for starting the rest mode; and a first determination unit, which is used to determine the target seat of the vehicle and adjust the target seat position to the rest mode to determine whether the conditions for starting the rest mode are met.
