Referring to fig. 3 to fig. 11, a signal reminding method for an electric vehicle according to an exemplary embodiment of the present invention is described below with reference to application scenarios of fig. 1 and fig. 2. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present invention, and the embodiments of the present invention are not limited in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.
As shown in fig. 3, which is a schematic flow chart of a signal reminding method of an electric vehicle according to an embodiment of the present invention, the electric vehicle according to the present invention operates in an automatic driving mode, and the signal reminding method of an electric vehicle according to the present invention may include the following steps:
s11, predicting whether the electric automobile needs to be steered according to the driving path planning of automatic driving, and if so, executing a step S12; otherwise, execution continues with step S11.
Specifically, in order to avoid repeated changes of the display state of the steering wheel indicator light in a short time, whether the electric vehicle needs to be steered or not can be predicted according to the flow shown in fig. 4a, and the following steps can be included:
and S21, acquiring the state information of the electric automobile according to the currently planned driving path.
In this step, the control system in the intelligent steering wheel driving assistance exchange system obtains the state information of the electric vehicle collected by the vehicle signal collection system, and the vehicle signal collection system can collect the state information of the electric vehicle according to the structure shown in fig. 4 b. The vehicle signal acquisition system acquires the state information of the electric automobile through a CANBUS bus in the electric automobile, and then transmits the state information to the control system for processing. Specifically, the vehicle signal acquisition system reads state information of equipment such as an automobile generator controller (ECU), a safety communication controller (SCU), an electronic control stability system (ESP), an Active Braking System (ABS), an Electric Power Steering (EPS) and the like through a CANBUS bus. It should be noted that the state information of more devices can be collected according to actual requirements, and specifically, corresponding circuit schemes can be designed in a derivative manner according to different requirements, and the existing controllers of the electric vehicle, the SCU and the like can also be used for direct control.
Preferably, the state information acquired by the present invention may include, but is not limited to, the current driving speed of the electric vehicle, and the like. The vehicle signal acquisition system can also acquire the current Ready state of the electric vehicle, the left turn lamp state/right turn lamp state of the electric vehicle and the like by checking the Ready state of the electric vehicle, confirming the left turn/right turn state of the electric vehicle and the like. Specifically, in an initial state, the vehicle signal acquisition system determines whether the vehicle is Ready, if so, determines whether a lamp control system of the electric vehicle is normal, starts the data acquisition device to acquire current running speed, steering wheel angle and other state information of the vehicle when the determination result is yes, and sends the acquired state information to a control system in the intelligent steering wheel auxiliary driving exchange system after the acquisition is completed. Because the real-time requirement of the electric automobile on data is high, when the data acquisition device fails to acquire data or fails to transmit data, the state information of the electric automobile at the current moment needs to be acquired again and is sent to the control system again after the acquisition result, and therefore the accuracy of the result of determining whether the electric automobile needs to turn can be guaranteed.
S22, when the steering wheel is predicted to rotate, determining whether the steering condition is met according to the predicted steering wheel rotating angle and the current running speed, and if the steering condition is met, executing the step S23; otherwise, step S24 is executed, namely: return is made to step S11.
In this step, the control system is configured to send a control signal to the light display system when it is determined that the steering wheel needs to turn, so that the light display system controls on and off of the flexible light source on the steering wheel according to the control signal. The control system can output control signals by combining various signals, drive the flexible light source to be turned on and off by controlling the light display system, can also realize a user-defined auxiliary light display system, and can design a circuit according to actual requirements.
In addition, after receiving the state information transmitted by the last layer, namely the vehicle signal acquisition system, the control system performs fusion processing on the state information, the information fusion processing method comprises filter processing algorithms such as Kalman and the like, machine learning algorithms and the like, and finally the state information is converted into a control instruction to control the application of the light display system, so that the aim of assisting driving of the intelligent steering wheel is fulfilled. In practical application, the control strategy relates to various factors, including information acquisition fusion, a control priority strategy and the like, and different control systems can be specifically designed according to different practical application scenarios, for example, a new hardware circuit can be designed to support the deployment of the control system, and the SCU software and hardware resource deployment control system can also be multiplexed.
In this step, when the control system detects that the steering wheel rotates, after determining the current rotation angle of the steering wheel, the control system first determines the minimum steering angle corresponding to the current driving speed when the steering lamp corresponding to the current driving speed is turned on according to the current acquired driving speed of the electric vehicle, then determines whether the current rotation angle of the steering wheel meets the minimum steering angle for left-turn or right-turn, and if so, determines that the electric vehicle can execute steering operation.
The minimum steering angle a is a steering angle corresponding to when the steering wheel is turned on at different driving speeds, and is obtained through a sufficient threshold test or machine learning. For example, the minimum steering angle is a, the steering angle at (-a, + a) indicates a critical interval for left or right turns, and 0 ° corresponds to the steering wheel balance point. When the steering angle of the steering wheel exceeds the threshold interval, the fact that the electric automobile needs to execute steering operation is indicated, and the actual size relation between the current steering angle of the steering wheel and the minimum steering angle needs to be judged when the electric automobile turns left or right. For example, when the steering wheel angle < -a indicates the minimum steering angle when the left turn light is on, it indicates that the electric vehicle will perform a left turn operation; when the steering wheel angle > + a indicates the minimum steering angle at the time when the right turn lamp is on, it indicates that the right turn operation is performed. Taking the minimum steering angle of 15 degrees as an example for explanation, if the detected current steering wheel rotation angle is +20 degrees and is greater than +15 degrees, it is determined that the current steering wheel rotation angle drives the right steering lamp to be on, that is, the electric automobile performs right-turn operation in the next step, that is, it is determined that the electric automobile needs right-turn; and if the detected current steering wheel rotation angle is-20 degrees and-20 degrees < -15 degrees, determining that the current steering wheel rotation angle drives the left steering lamp to be lightened, namely determining that the electric automobile can perform left-turning operation next step.
It is noted that the driving speed of the electric vehicle is different, and the corresponding minimum steering angle is different. For example, when the current running speed of the electric automobile is less than 30km/h, the corresponding minimum steering angle when a steering lamp of a steering wheel is turned on is 15 degrees; if the running speed of the electric automobile is between [30km/h and 70km/h), setting the minimum steering angle to be 10 degrees; if the driving speed of the electric vehicle is between [70km/h, 140km/h), the minimum steering angle is set to 7 °.
It should be noted that the maximum rotation angle θ needs to be set, which is generally 35 °, and the rotation angle of the steering wheel cannot exceed (- θ, + θ). Meanwhile, no matter how large the steering wheel is, the flexible light source of the left half part or the right half part of the light display system can only be kept on.
And S23, determining that the electric automobile needs to be steered.
Whether the electric vehicle needs to perform the steering operation can be accurately predicted based on the flow shown in fig. 4 a.
And S12, lighting the light source on the same side of the steering wheel as the target steering side.
Specifically, the light source on the side corresponding to the rotation direction on the steering wheel can be turned on according to the rotation direction of the steering wheel, so that the current running state of the electric vehicle of the user in the electric vehicle can be reminded.
Taking the current driving speed less than 30km/h as an example, under this speed condition, when the steering wheel is not rotated by an angle of (-15, +15), the turn signal lamp is driven to light, for example, when the steering wheel is rotated by an angle of < -15 >, the control circuit outputs a signal for turning the left turn signal lamp to light, and simultaneously lights the flexible light source arranged at the left half of the steering wheel, as shown in fig. 4c and 4d, the flexible light source at the left half of the central axis in fig. 4d emits light, for example, yellow light, and of course, other colors of light may also be emitted, and the invention is not limited herein. Similarly, when the steering wheel rotates by an angle > +15 °, the control circuit outputs a signal for turning on the right turn signal lamp, and synchronously turns on the flexible light source arranged on the right half side of the steering wheel, as shown in fig. 4e, the flexible light source on the right half side of the central shaft in fig. 4e emits light, for example, green light, and of course, other colors of light, which may be determined according to the actual situation, and is not limited herein, as can be seen from fig. 4d and 4e, no matter the left turn or the right turn, the central shaft is used as a reference, and the left turn is turned on; the right side of the central shaft is lightened when the electric automobile is turned right, the flexible light source cannot rotate along with the rotation angle, effective steering information can be provided for a user in the electric automobile, confusion is avoided, the user is prompted to perform the operation to be performed by the electric automobile in advance, and driving experience of the user is improved.
The invention utilizes the natural photosensitive effect of human eyes to assist a driver to steer by a flexible light source on a steering wheel and synchronizes to a steering lamp control system outside the electric automobile, thereby reminding other vehicles outside to pay attention to safe driving on one hand, realizing full automation of the steering process on the other hand, particularly under the state of unmanned driving or intelligent driving of the electric automobile, leading a user in the electric automobile to know the action to be executed next by the electric automobile through the lighted light source on the steering wheel without lowering the head to check a left turn signal lamp/right turn signal lamp indication system in a dashboard and manually shifting a steering rod, leading early warning for the user, particularly when an obstacle exists in front of the electric automobile in the intelligent driving state, leading the control system to know the next-executed steering operation of the electric automobile in advance by lighting the flexible light source on the steering wheel when the control system needs to execute the steering operation for avoiding hitting the obstacle according to a navigation planned path, therefore, after the user knows the next operation of the electric automobile through the lighted light source, on one hand, the user can know that the accident of colliding with the obstacle does not happen, and on the other hand, the user is prevented from generating panic.
Preferably, in order to better realize the intelligence of the electric vehicle, the method may further execute a process shown in fig. 5a, including the following steps:
s31, judging whether a self-test result of the electric automobile in the power-on self-test mode is received or not, and if yes, executing a step S32; otherwise, execution continues with step S31.
In this step, in an initial state of starting up, that is, before the electric vehicle is not started, the flexible light source on the steering wheel in the electric vehicle is in a normally off state, as shown in fig. 5 b; when a user presses a start button of the electric automobile or starts the electric automobile by using a key, the electric automobile starts to enter a starting self-checking mode, and a self-checking result is sent to the intelligent steering wheel auxiliary driving interaction system after the self-checking is finished, so that whether the self-checking result is received or not can be judged, whether the self-checking result is received or not can be periodically detected in the self-checking mode or whether the self-checking result is received or not can be detected in real time, and the method is not limited in the invention.
In this step, the power-on self-test can be performed by using the existing method, which is not limited in the present invention.
And S32, lighting the light source on the steering wheel in a mode corresponding to the self-detection result.
In this step, the intelligent steering wheel driving assistance interaction system receives a self-checking result of the power-on self-checking at the moment, and then lightens the flexible light source on the steering wheel according to a mode corresponding to the self-checking result, so that a user can be prompted whether the electric vehicle is normally started or not; for example, if the self-checking result is the self-checking result, the flexible light source on the steering wheel is turned on in a flashing lamp interaction mode, welcoming information and self-checking success information are prompted, the flexible light source is turned off after a preset time is delayed after the electric vehicle is initialized, and the preset time can be, but is not limited to, 5-10 s. When the self-checking result is that the self-checking fails, the flexible light source on the steering wheel is not lightened, or the flexible light source is lightened in a mode with extremely high frequency, or the light source on the steering wheel is lightened in a stroboscopic mode, but the light emitting color of the light source is red, and the like, so that the user is prompted that the self-checking fails. Fig. 5c shows an effect diagram of the flexible light source that is turned on after the self-check is successful, and the flexible light source on the steering wheel in fig. 5c emits orange light, but may also emit light of other colors, which may be determined according to actual situations, and is not limited herein.
Preferably, various abundant light signal combinations can be designed, a user can be reminded of paying attention to the fault problem of the electric automobile in a more humanized, more obvious and more friendly mode, and driving safety is improved.
Based on the flow shown in fig. 5a, the power-on self-checking system is automatically started, and a self-checking result is fed back, so that the method is efficient and accurate, and the automation and the intellectualization of self-checking diagnosis are improved compared with the method for judging whether the electric automobile has faults in the prior art by means of manual observation and the like. In addition, the self-checking result of the user is improved by utilizing the lighting mode of the light source on the steering wheel, and the user interaction friendliness is enhanced.
Preferably, the process shown in fig. 6a may be further executed, which includes the following steps:
s41, detecting whether the electric automobile has equipment which is not normally closed in the power-off mode, and if so, executing a step S42; otherwise, the flow ends.
In this step, the existing method may be adopted to detect whether the device in the electric vehicle is normally closed, which is not limited in the present invention.
And S42, lighting a light source on the steering wheel in a stroboscopic mode.
The user can often take place to forget to close the door window, forget to close air conditioner and condition such as size at the in-process of driving electric automobile or after using up electric automobile, and electric automobile self does not have any obvious suggestion at present, causes easily that the vehicle has bad conditions such as potential safety hazard and storage battery power consumption. In order to avoid the problem, the intelligent detection function is set, the states of all parts in the electric automobile are detected, and then the user is prompted in a conspicuous and friendly mode that the window of the electric automobile is not closed, and the driving experience of the user is improved. Fig. 6b is a schematic diagram of a hardware structure capable of implementing an intelligent detection function in the electric vehicle, and a microprocessor of a single-chip microcomputer TriCore 32bit is used to detect whether devices in the electric vehicle are normally closed, such as an air conditioner, a large lamp, a small lamp, a skylight, a window and a door, and the like. When the electric automobile is in a normal state, after the electric automobile is powered off or locked, if the electric automobile background system detects that a user does not close the window, does not close an air conditioner in the automobile, does not close a headlight, a small lamp, does not close a skylight or is not locked, a prompt signal is sent to the control system, so that the control system can light the flexible light source on the steering wheel and light the flexible light source in a stroboscopic mode, and the user can be prompted to process the equipment which is not normally closed. For example, the device may flash continuously and prominently, so as to prompt the user to turn off the device in time, a state where the flexible light source on the steering wheel is turned off is shown in fig. 5b, fig. 6c is an effect diagram after the flexible light source on the steering wheel is turned on when it is detected that the window is not turned off, the flexible light source mounted on the lower half portion of the steering wheel is turned on in a stroboscopic manner, and a light emitting color of the flexible light source may be orange, or of course, may be other light emitting colors, and may be specifically set according to actual conditions, where the light emitting color is not limited.
It should be noted that, in this case, considering the problem of the service life of the flexible light source, etc., the flexible light source of the steering wheel cannot flash violently all the time, the present invention may flash violently within a preset time period, and when the user turns off the device which is not normally turned off, the flexible light source may be actively turned off, or when the user turns off the device which is not turned off, the control system may turn off the flexible light source. After the preset time is exceeded, if the user does not close the non-closed equipment of the electric automobile all the time, an indication signal can be sent to the mobile terminal of the user through the vehicle-mounted wireless communication system, the indication signal carries an event that the equipment is not closed in the electric automobile, and meanwhile, the flexible light source is closed. Therefore, on one hand, the service time of the flexible light source is prolonged, and meanwhile, the purpose of early warning is achieved.
In the prior art, whether equipment in an electric automobile is in a closed state or not is often checked one by a user, an intelligent detection function is arranged in the electric automobile, whether the equipment in the electric automobile is not closed or not can be automatically detected under the condition that the electric automobile is locked or powered off by introducing the intelligent detection function, if yes, the user is reminded by driving a flexible light source on a steering wheel to light in a stroboscopic mode, the user is intuitively reminded, the user is prevented from forgetting, the safety of the electric automobile is improved, and when the user forgets to close the automobile window, the flexible light source is lightened in the stroboscopic mode, so that the automobile window is closed in time by the user, and the anti-theft risk of the electric automobile can be reduced.
Preferably, the signal reminding method for the electric vehicle provided by the invention can also execute the process shown in fig. 7, and comprises the following steps:
