Background

Along with the popularization of electric vehicles, the use frequency of the electric vehicle in people's life is more and more, but due to the characteristics of the electric vehicle, the problem of runaway can occur in the use process of the electric vehicle, for example, when the electric vehicle is an electric vehicle with a power-assisted mode, a user needs to step on a pedal with force when the user wants to start the power-assisted mode of the electric vehicle to ride, the flywheel can rotate at the moment, after the rotating speed of the flywheel reaches a certain degree, the electric vehicle can start the power-assisted mode so as to be convenient for the user to ride, if the flywheel and a chain are adhered (for example, the flywheel and the chain act together after rusting), the user pushes the electric vehicle, and after the pushing speed reaches a certain degree, the electric vehicle can also start the power-assisted mode, so that the speed of the electric vehicle is greater than the speed of the user, and the runaway condition can occur; for another example, when the user does not ride on the electric vehicle (the user is in a lifting state at this time), if the user rotates the control device for controlling the electric vehicle to advance, the speed of the electric vehicle is higher than the speed of the user, so that a runaway situation occurs, a runaway caused by any situation can cause hidden dangers to the safety of the user, and the safety of the user when using the electric vehicle is low.

One aspect of the present application relates to a control method of an electric vehicle. According to the method, after the current use state of the electric vehicle is determined to be the cart state, the driving device of the electric vehicle is forbidden to execute the driving operation, namely, when a user pushes the electric vehicle, the electric vehicle cannot convert electric energy into kinetic energy through the driving device, so that the speed of the electric vehicle is consistent with the speed of the user, the possibility of the electric vehicle flying is reduced, and the safety of the user when the electric vehicle is used is improved.

Before the application, in the related art, when the electric vehicle is in a cart state, the electric vehicle may fly, which may cause a hidden danger to the safety of the user. However, according to the control method of the electric vehicle provided by the application, after the current use state of the electric vehicle is determined to be the cart state, the driving device of the electric vehicle is prohibited from executing the driving operation, that is, when a user pushes the electric vehicle, the electric vehicle cannot convert electric energy into kinetic energy through the driving device, so that the speed of the electric vehicle is consistent with the speed of the user, the probability of the electric vehicle flying is reduced, and the safety of the user when the user uses the electric vehicle is improved.

Example one

Fig. 1 is a schematic flowchart of a control method for an electric vehicle according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:

step 101, obtaining current riding parameter information of the electric vehicle.

Specifically, since the riding parameter information of the electric vehicle is different when the user rides the electric vehicle (at this time, the use state of the electric vehicle is a riding state) and when the user pushes the electric vehicle (at this time, the use state of the electric vehicle is a pushing state), for example, when the electric vehicle is in the riding state and the pushing state, the speed of the electric vehicle, the current output by the power supply device, the pressure on the ground, the pressure applied to the electric vehicle, the total pressure on the pedal plate, the inclination direction of the electric vehicle, the included angle between the horizontal plane and the inclination direction of the electric vehicle, and the like are different, that is, the riding parameter information can embody the current use state, and after the current riding parameter information of the electric vehicle is acquired, a reference basis can be provided for subsequent processing.

It should be noted that the riding parameter information in the embodiment of the present application may be collected according to actual needs, and when the riding parameter information is collected, the corresponding sensor or collection device may be used to collect the riding parameter information, and the specific riding parameter information may be set according to specific needs, which is not specifically limited herein, but all the riding parameter information capable of analyzing the current use state of the electric vehicle all belong to the protection scope of the embodiment of the present application.

It should be noted again that the types of the electric vehicles related in the embodiments of the present application include an electric vehicle with a power-assisted mode (such an electric vehicle, when a user rides the electric vehicle, the user can provide forward kinetic energy for the electric vehicle through both feet, and after the electric vehicle reaches a certain speed, the electric vehicle also provides forward kinetic energy for itself, and at this time, the electric vehicle advances through the kinetic energy of itself and the kinetic energy provided by the user, or the user rotates the control device for controlling the electric vehicle to advance, so that the electric vehicle provides kinetic energy for itself), and an electric vehicle without a power-assisted mode (such an electric vehicle, when the user rides the electric vehicle, the user can only rotate the control device for controlling the electric vehicle to advance, so that the electric vehicle provides kinetic energy for itself).

And 102, determining the current using state of the electric vehicle according to the riding parameter information.

Specifically, after the current use state (including the riding state and the cart state) of the electric vehicle is determined according to the riding parameter information, whether the user is riding the electric vehicle or pushing the electric vehicle can be determined, so that a basis is provided for subsequent control according to the current use state of the electric vehicle.

And 103, prohibiting a driving device of the electric vehicle from executing driving operation when the using state is the trolley state.

Specifically, no matter what type of electric vehicle is, when a user pushes the electric vehicle, if the driving device performs the driving operation, the speed of the electric vehicle is greater than the speed of the user under the action of the driving force of the driving device, so that when the current use state of the electric vehicle is a cart state, in order to reduce the possibility of the electric vehicle flying, the driving device of the electric vehicle needs to be prohibited from performing the driving operation, and after the driving device is prohibited from performing the driving operation, the electric vehicle cannot provide the driving force for the electric vehicle, so that the speed of the electric vehicle can be basically consistent with the speed of the user, and the safety of the user when the user uses the electric vehicle is improved.

In a possible embodiment, in step 102, the riding parameter information may be compared with a target threshold, when the riding parameter information is greater than or equal to the target threshold, the current using state of the electric vehicle is determined as the riding state, and when the riding parameter information is less than the target threshold, the current using state of the electric vehicle is determined as the pushing state.

Specifically, the riding parameter information when the electric vehicle is in the riding state is different from the riding parameter information when the electric vehicle is in the stroller state, and for the same riding parameter information, the value corresponding to the riding parameter information in the riding state is greater than the value of the riding parameter information in the stroller state, for example: the speed of the electric vehicle in the riding state is greater than the speed of the electric vehicle in the pushing state, the current output by the power supply device when the electric vehicle is in the riding state is greater than the current output by the power supply device when the electric vehicle is in the pushing state, the pressure on the ground when the electric vehicle is in the riding state is greater than the pressure on the ground when the electric vehicle is in the pushing state, and the like.

It should be noted that, the specific target threshold may be set according to the corresponding riding parameter information and the actual need, and is not specifically limited herein.

It should be noted again that specific types of the riding parameter information may be set according to actual needs, and are not specifically limited herein, but all riding parameter information of the electric vehicle in a riding state is greater than that in a stroller state, which belongs to the protection scope of the embodiment of the present application.

In one possible embodiment, the value of the operating current of the drive means, the value of the pressure on the seat, and the first sum of the pressures on the electric vehicle at the locations for placing the feet of the user.

Specifically, when the electric vehicle is in a riding state, the power device can provide electric energy for the driving device to assist the driving device or perform normal driving operation, and no matter what type of electric vehicle is, when the electric vehicle is in the riding state, the electric vehicle is in a load state, when the electric vehicle is in a pushing state, the electric vehicle is in an idle load state or a low load state, and for different load states, the working current of the driving device is different, so that the current use state of the electric vehicle can be determined by the working current value of the driving device.

When the electric vehicle is in a riding state, a user sits on a seat of the electric vehicle, and when the electric vehicle is in a pushing state, the user cannot sit on the seat of the electric vehicle, so that the current use state of the electric vehicle can be determined through a pressure value on the seat.

When the electric vehicle is in a riding state, a user can prevent feet from being placed at a specific position of the electric vehicle, taking the electric vehicle with a power-assisted mode as an example, the user can place the feet on a pedal (a device for providing kinetic energy for the electric vehicle through the feet, commonly called a pedal), or can place the front wheel of the two-foot electric vehicle and a seat on a plane structure, taking the electric vehicle without the power-assisted mode as an example, the user can prevent the feet from being placed on the plane structure between the front wheel of the foot electric vehicle and the seat, or place the feet of the user on other structures, when the electric vehicle is in a pushing state, the feet of the user are not in contact with the specific position, so that when the electric vehicle is in different use states, a first total pressure value at the position for placing the feet of the user is different, and therefore, the current use state of the electric vehicle can be determined through the first total pressure value at the position for placing the feet of the user.

It should be noted that, the current using state of the electric vehicle can be determined by using the at least one type of riding parameter information, and the accuracy of the determination result can be improved along with the increase of the type of the riding parameter information, of course, the riding parameter information may also include the speed of the electric vehicle, the pressure of the electric vehicle to the ground, and the like, and the specific type of the riding parameter information may be set according to actual needs, which is not specifically limited herein, and the above embodiment is only an exemplary description of the riding parameter information, and does not limit the embodiment of the present application.

It should be noted that, the specific use of several riding parameter information to judge the current use state of the electric vehicle may be set according to actual needs, and is not specifically limited herein.

In a possible embodiment, when the riding parameter information is the operating current value of the driving device, in the step 102, the operating current value and the target current threshold value may be compared; when the working current value is larger than or equal to the target current threshold value, determining that the current using state of the electric vehicle is the riding state; and when the working current value is smaller than the target current threshold value, determining that the current use state of the electric vehicle is the cart state.

Specifically, when the usage state of the electric vehicle is the riding state, the driving device may be in the load state, and when the usage state of the electric vehicle is the pushing state, the driving device may be in the no-load state or the low-load state, so that the working current value of the driving device when the usage state of the electric vehicle is the riding state is greater than the working current value of the driving device when the usage state of the electric vehicle is the pushing state, and meanwhile, since the current value of the driving device when the usage state of the electric vehicle is the riding state may change within one value interval, and the current value of the driving device when the usage state of the electric vehicle is the pushing state may change within another value interval, a target current threshold may be set according to the two intervals, and then the target current threshold and the working current value of the driving device are compared to determine the current usage state of the electric vehicle.

For example, at this time, when a user rotates a control device for controlling the electric vehicle to move forward, the battery system may provide an instantaneous operating current for the driving device, and since the operating currents of the electric vehicle in different load states are different, the instantaneous operating current may be used to detect the use state of the electric vehicle.

It should be noted that, the specific target current threshold may be set according to the current variation interval when the electric vehicle is in different use states, for example, when the electric vehicle is in a riding state, the numerical interval of the current value of the driving device is [5, 10], and when the numerical interval of the current value of the driving device is [0,1], the target current threshold may be set to 3.

In one possible embodiment, when the riding parameter information is a pressure value on the seat, the pressure value may be compared with a target pressure threshold in executing step 102; when the pressure value is larger than or equal to the target pressure threshold value, determining that the current using state of the electric vehicle is the riding state; and when the pressure value is smaller than the target pressure threshold value, determining that the current using state of the electric vehicle is the cart state.

Specifically, when the using state of the electric vehicle is a riding state, a user can sit on a seat of the electric vehicle, and when the using state of the electric vehicle is a pushing state, the user cannot generate any acting force on the electric vehicle, or the generated acting force is small, so that the current using state of the electric vehicle can be judged by setting a target pressure threshold value and then utilizing the target pressure threshold value and the pressure value.

For example, when the usage state of the electric vehicle is a riding state, the pressure value on the seat may be changed between [10, 1000], and when the usage state of the electric vehicle is a pushing state, the pressure value on the seat may be changed between [0,7], and then the current usage state of the electric vehicle may be determined by the target pressure threshold and the pressure value on the seat, where the above example is merely an exemplary description of the target pressure threshold, and does not limit the embodiment of the present application, and the specific target pressure threshold may be set according to actual needs, and is not specifically limited herein.

It should be noted that the pressure value on the seat may be obtained by a pressure sensor, the pressure sensor may collect the pressure value vertically acting on the seat, and may also collect the pressure value acting on the seat in other directions, and the obtaining manner of the pressure value on the seat may be set according to actual needs and actual environments, which is not specifically limited herein.

In one possible embodiment, when the riding parameter information is a first total pressure value at a position on the electric vehicle for placing the feet of the user, the first total pressure value and the target total pressure threshold value may be compared when step 102 is executed; when the first total pressure value is larger than or equal to the target total pressure threshold value, determining that the current using state of the electric vehicle is the riding state; and when the first total pressure value is smaller than the target total pressure threshold value, determining that the current using state of the electric vehicle is the cart state.

Specifically, when the usage state of the electric vehicle is a riding state, the feet of the user may be placed at specific positions (the specific positions are described in detail above, and are not described in detail herein), so as to generate an acting force on the specific positions, and when the usage state of the electric vehicle is a pushing state, the feet of the user may not generate an acting force on the specific positions, or the generated acting force is small, so that the first total pressure value when the usage state of the electric vehicle is the riding state is greater than the first total pressure value when the usage state of the electric vehicle is the pushing state, so as to set a target total pressure threshold value, and then the target total pressure threshold value and the pressure value are used to determine the current usage state of the electric vehicle.
