Traditional car driving methods rely on the interaction of the accelerator pedal, brake pedal, and steering wheel for control. In this control mode, the driver needs to frequently switch between the accelerator and brake pedals, and in emergency situations, there is a high possibility of accidentally pressing the accelerator pedal.

[0051] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail with reference to the accompanying drawings. The specific operating methods in the method embodiments can also be applied to device embodiments or system embodiments. It should be noted that in the description of the present application, "multiple" is understood as "at least two". "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist at the same time, and B exists alone. A is connected to B, which can represent the following two situations: A is directly connected to B and A is connected to B through C. In addition, in the description of the present application, words such as "first" and "second" are only used to distinguish the purpose of description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0052] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0053] First, a vehicle control method provided in an embodiment of the present application is applied to the system architecture of the present application, in which the system architecture includes a vehicle controller, a steering angle sensor, a motor controller and a motor. The vehicle controller is connected to the steering angle sensor, the vehicle controller is connected to the motor controller, and the motor controller is connected to the motor. The main control circuit of this system is as follows Figure 1 shown.

[0054] When acceleration is required, the driver can control the acceleration of the vehicle by manipulating the steering wheel. The vehicle controller in the vehicle detects the steering of the steering wheel to generate an acceleration instruction and sends the acceleration instruction to the motor controller. The motor controller will control the motor to increase the torque for acceleration according to the acceleration instruction. In this way, the acceleration of the vehicle can be controlled by the steering wheel, so that the corresponding acceleration instruction is executed through special operation of the steering wheel when the accelerator pedal is canceled, thereby preventing the driver from stepping on the accelerator by mistake and reducing the incidence of vehicle accidents. Among them, the method and device described in the embodiments of the present application are based on the same technical concept. Since the principles of the problems solved by the method and the device are similar, the embodiments of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0055] Specifically, refer to Figure 2 FIG. 1 is a flow chart of a vehicle control method provided by an embodiment of the present application, the method comprising:

[0056] S11, obtaining a first steering switch signal of the steering wheel;

[0057] In the embodiment of the present application, the method can be applied to Figure 1In the system control circuit shown in the figure, in order to prevent the driver from accidentally stepping on the accelerator while driving the vehicle and to increase the driver's driving pleasure, the method uses special operation of the steering wheel to replace the acceleration function of the accelerator.

[0058] First, in order to obtain the first steering switch signal, a first flag and a second flag are configured in the system. The first flag is used to identify whether the steering wheel is rotating clockwise, and the second flag is used to identify whether the steering wheel is rotating counterclockwise.

[0059] Obtaining a first logic value of a first flag bit and a second logic value of a second flag bit;

[0060] Performing a logical AND operation on the first logic value and the second logic value to obtain a first operation result;

[0061] A first steering switch signal of the steering wheel is generated according to the first calculation result.

[0062] Specifically, the vehicle controller will receive the steering wheel steering angle signal from the angle sensor. When the steering wheel rotates clockwise, the clockwise rotation of the steering wheel is defined as flag A, that is, the first flag, and the logic value of flag A is set to 1; when the steering wheel rotates counterclockwise, the counterclockwise rotation of the steering wheel is defined as flag B, that is, the second flag, and the logic value of flag B is set to 1.

[0063] If no clockwise or counterclockwise rotation of the steering wheel is detected within the delay time, the logic value of flag A is set to 0 or the logic value of flag B is set to 0; for example, the delay time can be set to 50ms. If no forward or reverse switching of the steering wheel is detected within the 50ms delay time, the logic value of flag A and the logic value of flag B are set to 0 respectively.

[0064] After performing a logical AND operation on the logical value of flag A or performing a logical AND operation on the logical value of flag B, if the resulting logical value of flag A is 1 or the logical value of flag B is 1, the angle sensor detects a steering wheel steering angle signal indicating that the steering wheel is rotating clockwise, or a steering wheel steering angle signal indicating that the steering wheel is rotating counterclockwise; if the resulting logical value of flag A is 0 or the logical value of flag B is 0, the steering wheel is not rotating clockwise or the steering wheel is rotating counterclockwise.

[0065] Further, a logical AND operation is performed on the obtained logical value of flag A and the logical value of flag B; after the logical value of flag A and the logical value of flag B are performed on the logical AND operation, when the obtained logical value is 1, a steering switching action representing the steering wheel turning from clockwise to counterclockwise or from counterclockwise to clockwise is obtained.

[0066] The angle sensor detects the steering wheel steering angle signal when the steering wheel rotates from clockwise to counterclockwise or from counterclockwise to clockwise; further, the angle sensor sends the received steering wheel steering angle signal to the vehicle controller, thereby generating a corresponding first steering switch signal.

[0067] S12, when a second steering switch signal of the steering wheel is acquired, determining a time interval between receiving the first steering switch signal and receiving the second steering switch signal;

[0068] First, after the steering wheel steering switch signal has been detected in step S11, the angle sensor will continue to detect the steering wheel corresponding to the steering switching action, such as the steering wheel turning from counterclockwise to clockwise, or the steering wheel turning from clockwise to counterclockwise, and the angle sensor will further send the received steering wheel steering angle signal to the vehicle controller, thereby generating a corresponding second steering switch signal.

[0069] Furthermore, the vehicle controller calculates the time interval between the first steering switch signal and the second steering switch signal.

[0070] S13, determining whether the time difference is less than a preset time interval;

[0071] First, after receiving the first steering switch signal and the second steering switch signal, the vehicle controller will have two different working states: one is to execute the first target vehicle speed increase instruction, and the other is not to execute the first target vehicle speed increase instruction, and the vehicle maintains the target speed without changing;

[0072] Furthermore, the vehicle controller is required to determine whether the time interval between the first steering switch signal and the second steering switch signal is less than a preset time interval when receiving the first steering switch signal and the second steering switch signal.

[0073] like Figure 3 、 Figure 4As shown, when the vehicle starts, the corresponding target speed increase command is executed. For example, the preset time interval between the first and second steering switch signals is set to 300ms. When it detects that the time interval between the first and second steering switch signals is less than 300ms, the vehicle controller will execute the first target speed increase command, setting the target speed to the cumulative value of the current speed and the first target increase stage. If the time interval between the first and second steering switch signals is greater than the preset time interval, the vehicle will maintain the target speed unchanged. At this time, if the vehicle is in the starting state or the unpowered coasting state, the target speed is adjusted to the cumulative value of the current speed and the first target increase speed. If the vehicle is in the driving state, it will continue to determine whether the current target speed has accumulated the first target increase speed. If the first target increase speed has accumulated, the second target increase speed will continue to accumulate.

[0074] Therefore, after determining the time interval between the first steering switch signal and the second steering switch signal, there will be two different results. One is that the time difference between the first steering switch signal and the second steering switch signal is less than the preset time interval, and the other is that the time difference between the first steering switch signal and the second steering switch signal is greater than the preset time interval.

[0075] If it is detected that the time interval between the first steering switch signal and the second steering switch signal is less than the preset time interval, step S14 is executed; if it is detected that the time interval between the first steering switch signal and the second steering switch signal is greater than the preset time interval, step S15 is executed.

[0076] S14 , responding to the first target vehicle speed increase instruction, accelerating the vehicle from the current vehicle speed to the target vehicle speed after the target vehicle speed is increased.

[0077] First, before responding to the first target speed increase instruction, it is necessary to determine the first target speed increase value of the vehicle. In order to determine the first target speed increase value, it is necessary to further determine the corresponding first target increase stage. To determine the first target increase stage, it is necessary to further determine the target increase condition E.

[0078] To obtain the target increase condition E, upon detecting the first steering switch signal, a third logic value of the third flag bit and a fourth logic value of the fourth flag bit are obtained, wherein the third flag bit and the fourth flag bit represent a target speed increase event of the vehicle;

[0079] A logical OR operation is performed on the third logic value of the third flag bit and the fourth logic value of the fourth flag bit to obtain the logic value of the target amplification condition E.

[0080] For example, the flag A indicating that the steering wheel rotates clockwise and the flag B indicating that the steering wheel rotates counterclockwise are logically ANDed to obtain the flag G. If the logic value of the flag G is 1 at this time, the flag C, i.e., the third flag, and the flag D, i.e., the fourth flag, will be triggered to perform a logical operation. When the logic value of the flag G is 1, the obtained flag is not limited to two flags but can be multiple flags. The flag C and flag D are used here for illustration.

[0081] Furthermore, at this time, the steering wheel has switched forward and reverse, and the flag bit C and the flag bit D will perform a logical operation; for example, if the logic value of the flag bit C is 0 at this time, the logic value of the flag bit C will be changed to 1, and the logic value of the flag bit D will not be changed. The logic value of the flag bit D is 0 at this time and will continue to be 0, and the logic value of the flag bit D is 1 at this time and will continue to be 1; if the logic value of the flag bit C is 1, it is necessary to judge the logic value of the flag bit D. If the logic value of the flag bit D is 0, it will be changed to 1. If the logic value of the flag bit D is 1, it will remain unchanged. The above logical operation is as follows Figure 5 、 Figure 6 Place.

[0082] Furthermore, a logical OR operation is performed on the logical values of the flag bit C and the flag bit D after the logical operation, and a target amplification condition E is obtained.

[0083] When the target increase condition E=1, the first target vehicle speed increase value corresponding to the first target increase stage can be determined, thereby generating a first target vehicle speed increase instruction including the first target vehicle speed increase value.

[0084] When the logic value of the target increase condition E is 1, the corresponding increase stage is determined to be the first target increase stage, and the first target increase stage corresponds to the first target vehicle speed increase value. In the embodiment of the present application, the corresponding relationship between each target increase stage and the corresponding vehicle speed increase value is shown in Table 1:

[0085]

[0086] Table 1;

[0087] After obtaining the vehicle speed increment value corresponding to the first target increment phase, the first target speed increment instruction is generated, including the first target speed increment value. If the first target increment phase has not yet been executed, the target speed is incremented by the vehicle speed increment value corresponding to the first target increment phase F1. If the first target increment phase has already been executed, the second target increment phase is executed, and the target speed is incremented by the vehicle speed increment value corresponding to the second target increment phase F2. When the target increment condition is 1, if flags C and D trigger rising edges, the current target increment phase is determined, and the corresponding target speed is increased according to the F value.

[0088] After determining the first target vehicle speed increment value corresponding to the first target increment stage, the vehicle controller will respond to the first target vehicle speed increment instruction to increase the target vehicle speed by the first target vehicle speed increment value; and continue to detect the third steering switch signal; if the third steering switch signal is detected, determine whether the time interval between the second steering switch signal and the third steering switch signal is less than a preset time interval;

[0089] If the time interval between the second steering switch signal and the third steering switch signal is less than the preset time interval, the second target vehicle speed increase value corresponding to the second target increase stage is determined, and a second target vehicle speed increase instruction including the second target vehicle speed increase value is generated. The vehicle controller will respond to the second target vehicle speed increase instruction to increase the target vehicle speed by the second target vehicle speed increase value.

[0090] For example, the preset time interval is 300ms, and the time interval between the second steering switch signal and the third steering switch signal is less than the preset time interval of 300ms. At this time, the vehicle will receive an acceleration command and determine the target speed as the cumulative value of the current speed, the first target speed increase value, and the second target speed increase value, and accumulate the speed values of the corresponding increase stages in Table 1. For example, if the current speed is 30KM / H, in the first target increase stage, the speed will be increased to (30+5)KM / H, and in the second target increase stage, the speed will be increased to (35+10)KM / H.

[0091] Specifically, the vehicle has different operating states at this time. Before executing the acceleration command, it is necessary to judge the vehicle's operating state at this time, and then adjust the corresponding target speed according to the different operating states;

[0092] In an embodiment of the present application, the vehicle operating states include: starting state, unpowered gliding state and driving state; if the vehicle is in the starting state or unpowered gliding state at this time, the vehicle controller adjusts the target speed to the cumulative value of the vehicle's current speed and the speed corresponding to the first target increase stage.

[0093] For example, if the vehicle is just starting, the vehicle controller adjusts the target speed to 0 plus the speed corresponding to the first target amplification stage of 5 km / h, and obtains a target speed of 5 km / h; if the vehicle is in a non-powered gliding state, the vehicle controller adjusts the target speed to the cumulative value of the current instantaneous speed and the speed corresponding to the first target amplification stage. For example, if the current instantaneous speed is 30 km / h, the vehicle controller adjusts the target speed to 30 km / h plus the speed corresponding to the first target amplification stage of 5 km / h, and obtains a target speed of 35 km / h.

[0094] If the vehicle is in the driving state and detects an acceleration command, the vehicle controller will first detect the current target speed and determine the current target increase stage based on the detected acceleration command. For example, if the current target speed is 50KM / H, if the speed corresponding to the first target increase stage is already included at this time, the target speed is updated to 50KM / H plus the speed value corresponding to the second target increase stage. If the current target speed already includes the speed value corresponding to the first target increase stage and the speed value corresponding to the second target increase stage, the target speed is updated to 50KM / H plus the speed value corresponding to the third target increase stage.

[0095] Specifically, the current target speed of the vehicle when in driving state is 50KM / H. The vehicle controller will first determine the current accumulated target acceleration stage of the vehicle. If the vehicle has executed the first acceleration command, the current target speed already includes the F1 value of 5KM / H corresponding to the first target acceleration stage. The target speed will accumulate the F2 value of 10KM / H corresponding to the second target acceleration stage to generate a new target speed value of 60KM / H.

[0096] If the vehicle's target speed at this time already includes the F1 value of 5KM / H corresponding to the first target amplification stage and the F2 value of 10KM / H corresponding to the second target amplification stage, the vehicle controller will update the target speed to the current target speed plus the F3 value of 15KM / H corresponding to the third target amplification stage, generating a new target speed value of 65KM / H, and so on.

[0097] Through the above operation, the corresponding acceleration command is executed through special operation of the steering wheel when the accelerator pedal is cancelled, thereby avoiding the driver from accidentally stepping on the accelerator pedal and reducing the accident rate.

[0098] S15: The vehicle maintains the target speed without changing.

[0099] Furthermore, when it is determined that the time interval between the first turn switching signal and the second turn switching signal is greater than the preset time interval, the vehicle will maintain the current operating state.

[0100] Specifically, if the vehicle is stationary at this time, when the time interval between the first steering switch instruction and the second steering switch instruction is greater than the preset time interval, the vehicle will not execute the acceleration instruction and continue to remain stationary.

[0101] If the vehicle is in an unpowered gliding state at this time, when the time interval between the first steering switch command and the second steering switch command is greater than the preset time interval, the vehicle will not execute the acceleration command and continue to maintain the unpowered gliding state. At this time, since the vehicle controller interrupts the torque output, the vehicle will glide unpowered until the vehicle stops, or when the acceleration command is detected again, it will continue to respond to the acceleration signal to increase the vehicle speed to the target speed.

[0102] If the vehicle is in the driving state at this time, when the time interval between the first steering switch instruction and the second steering switch instruction is greater than the preset time interval, the vehicle will not execute the acceleration instruction, and the vehicle will continue to drive at the current target speed. Figure 7 、 Figure 8 As shown, according to the different operating states of the above vehicles, the corresponding target vehicle speed increase instructions are executed.

[0103] The vehicle is driven based on the target speed, and the driving torque is set to be positively correlated with the difference between the target speed and the current speed. That is, the greater the difference between the target speed and the current speed, the greater the driving torque.

[0104] If the brake pedal is pressed, the vehicle controller will receive a braking signal and brake the vehicle. At this time, the vehicle interrupts the target speed increase cycle, and the target increase events C, D, target increase conditions E, target increase stage F, target speed and flag G are forced to 0.

[0105] Example 2:

[0106] Corresponding to the vehicle state adjustment method provided in the first embodiment, the present application also provides a vehicle state adjustment device, referring to Figure 9 FIG. 1 is a schematic structural diagram of a vehicle state adjustment device provided by the present application, the device comprising:

[0107] An acquisition module 901 is configured to acquire a first steering switch signal and a second steering switch signal of a steering wheel, and acquire a time interval between the first steering switch signal and the second steering switch signal of the steering wheel;

[0108] The processing module 902 is configured to determine whether a time interval between the first steering switch signal and the second steering switch signal of the steering wheel is less than a preset time interval.

[0109] In one possible design, the processing module 902 is specifically configured to determine a time interval between the first steering switch signal and the second steering switch signal;

[0110] If the time interval between the first steering switch signal and the second steering switch signal is less than the preset time interval, responding to the first target vehicle speed increase instruction, the target vehicle speed is increased and the vehicle is accelerated to the target vehicle speed;

[0111] If the time interval between the first turn switching signal and the second turn switching signal is greater than the preset time interval, the vehicle maintains the target speed without changing.

[0112] In one possible design, the device further includes:

[0113] A generating module, used for generating an acceleration instruction including a vehicle speed increase value;

[0114] The control module is used to respond to the target vehicle speed increase instruction and accelerate the vehicle to the target vehicle speed after the target vehicle speed increases.

[0115] Based on the above-mentioned device, after the vehicle controller detects the first steering switch signal and the second steering switch signal of the steering wheel, it compares the time interval between the first steering switch signal and the second steering switch signal of the steering wheel with the preset time interval between the first steering switch signal and the second steering switch signal of the steering wheel. Based on the comparison result, different operating states are determined. If the time interval is less than the preset time interval, the acceleration command is executed and the vehicle speed is accelerated from the current speed to the target speed. If the time interval is greater than the preset time interval, the vehicle maintains the target speed without changing. In this way, the corresponding acceleration command is executed through special operation of the steering wheel, preventing the driver from accidentally stepping on the accelerator and reducing the incidence of vehicle accidents.

[0116] Based on the same inventive concept, an electronic device is also provided in the embodiment of the present application, and the electronic device can realize the function of the aforementioned vehicle state control, referring to Figure 10 , the electronic device includes:

Figure 10 In the example, the processor 1001 and the memory 1002 are connected via the bus 1000. Figure 10 The bus 1000 can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 10 The diagram is represented by only one thick line, but this does not mean that there is only one bus or one type of bus. Alternatively, the processor 1001 may also be referred to as a controller, without limitation to the name.

[0118] In the embodiment of the present application, the memory 1002 stores instructions that can be executed by at least one processor 1001.

[0120] In one possible design, processor 1001 may include one or more processing units. Processor 1001 may integrate an application processor and a modem processor. The application processor primarily processes the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 1001. In some embodiments, processor 1001 and memory 1002 may be implemented on the same chip. In some embodiments, they may also be implemented on separate chips.

[0121] The processor 1001 can be a general-purpose processor, such as a central processing unit (CPU), a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component, and can implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of this application.
