Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With conventional fuel-fired vehicles, such vehicles, during travel, provide a booming sound sufficient for pedestrians to notice the presence of the vehicle due to the exhaust of the engine. Unlike a vehicle that burns fuel, an electric vehicle has a small sound during driving, and pedestrians may not notice the presence of the electric vehicle, thereby possibly causing a safety hazard. Accordingly, electric vehicles are generally equipped with various buzzers and alarms to alert pedestrians of the presence of vehicles.
When the existing Vehicle prompting method is used for enabling the electric Vehicle to send out prompting sounds, a Vehicle Control Unit (VCU) of the electric Vehicle is connected with various buzzers and alarms so as to Control different buzzers or alarms to send out corresponding prompting sounds. For example, if the VCU determines that the electric vehicle is in a reverse state, the VCU may control a reverse buzzer to emit a warning tone such as "tic-tic". If the VCU determines that the electric automobile is in a low-speed running state, the VCU can control the low-speed alarm to emit a prompt sound simulating the sound emitted by the running process of the fuel-burning vehicle.
In the existing vehicle prompting method, the VCU needs to be connected with various buzzers and alarms, so that the control circuit of the electric vehicle is high in complexity and low in flexibility.
In view of the above problems of the existing vehicle prompting method, the application provides a vehicle prompting method, and an electronic control unit of a vehicle only needs to be connected with one alarm, so that the complexity of a control circuit of an electric vehicle is reduced. Under this connected mode, the electronic control unit of vehicle can acquire the multiple operating mode of going of vehicle to according to the operating mode of going of difference of vehicle, the alarm of control vehicle sends the prompt tone that corresponds with the operating mode of going to the vehicle outside. According to the vehicle prompting method, the complexity of the vehicle control circuit can be reduced and the flexibility of the vehicle control circuit is improved under the condition that the vehicle sends different prompting sounds under different running conditions.
It should be understood that the vehicle prompting method provided by the application can be applied to a pure electric vehicle or a hybrid electric vehicle. The hybrid vehicle may be, for example, a hybrid vehicle using gasoline and electricity (the oil may be a diesel engine, a gasoline engine, or the like), or a hybrid vehicle using natural gas and electricity. The main execution body of the vehicle presentation method is an Electronic Control Unit, which may be, for example, a VCU of a vehicle or another Electronic Control Unit (ECU) having a processing function mounted on the vehicle.
The technical solution of the present application will be described in detail with reference to specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a schematic view of an application scenario of the vehicle prompting method provided by the present application. As shown in fig. 1, the vehicle prompting method provided by the application is applied to a vehicle comprising an electronic control unit and an alarm.
The electronic control unit is used for controlling the alarm to send out prompt tones corresponding to the running conditions to the outside of the vehicle based on the running conditions of the vehicle. The alarm is installed outside the vehicle and used for giving out prompt tones corresponding to running conditions to the outside of the vehicle. It will be appreciated that the present application is not limited to the particular location on the exterior of the vehicle in which the alarm is mounted, and that figure 1 is merely an example showing possible locations for the alarm.
Fig. 2 is a schematic flow chart of a vehicle prompting method provided by the present application. As shown in fig. 2, the method comprises the steps of:
and S101, acquiring the running condition of the vehicle.
The running condition of the vehicle (which may also be referred to as an automobile running condition) refers to an operating condition of the vehicle during running. For example, the driving condition of the vehicle may include a movement form of the vehicle, such as driving conditions of vehicle starting, accelerating, uniform speed, decelerating, ascending and descending, parking and the like. The driving conditions of the vehicle may also include the control modes of the vehicle, such as gear shifting, coasting (gear-out coasting, neutral coasting, accelerating coasting, parking coasting, etc.), braking (emergency braking, speed control braking, brake braking, etc.), accelerator speed control, turning, reversing, etc. In addition, the load state of the vehicle, such as no load, full load (i.e., the rated load of the vehicle), overload (the vehicle load exceeds the rated load), and the like, may also be used as the running condition of the vehicle.
Alternatively, the electronic control unit may acquire a signal related to the driving condition of the vehicle, and then determine the driving condition of the vehicle according to the acquired signal.
For example, the electronic control unit can acquire a gear signal of the vehicle. And if the gear signal indicates that the vehicle is in a reverse state, determining that the running condition of the vehicle is reverse. The electronic control unit may further acquire a steering signal of the vehicle, and determine the running condition of the vehicle as a turn if the steering signal indicates that the vehicle is in a turning state (left turn or right turn).
The electronic control unit can also acquire a vehicle speed signal of the vehicle, and if the vehicle speed represented by the vehicle speed signal is lower than a preset threshold, the running condition of the vehicle is determined to be low-speed running with the speed lower than the preset threshold. The preset threshold may be determined according to an industry standard of an electric vehicle low-speed driving prompt tone or manual experience, and is stored in the electronic control unit in advance. Alternatively, the preset threshold may be determined by the electronic control unit according to the environment of the vehicle. For example, the predetermined threshold value corresponding to a vehicle traveling on a street (which may be more crowded) is less than the predetermined threshold value corresponding to a vehicle traveling on a highway (which may be less crowded).
Optionally, the electronic control unit may be connected to a corresponding sensor, for example, to obtain the signal collected by the sensor. For example, the electronic control unit may acquire a right turn signal of the vehicle collected by the steering sensor, so as to determine that the driving condition of the vehicle is a right turn. The electronic control unit can also acquire a low-speed running signal of the vehicle acquired by the vehicle speed sensor, so that the running condition of the vehicle is determined to be low-speed running. The electronic control unit can also acquire a reversing signal of the vehicle acquired by the gear sensor, so that the running condition of the vehicle is determined to be reversing.
It should be understood that the present application does not limit how the electronic control unit obtains the driving condition of the vehicle. The above-described methods are only possible implementations provided by the present application. During specific implementation, the electronic control unit can also acquire the running condition of the vehicle in other modes.
And S102, judging whether the driving working condition meets the prompt tone output condition.
For example, the warning tone output condition may include that the driving condition of the vehicle is reverse, or the driving condition of the vehicle is turning, the driving condition of the vehicle is low-speed driving with a speed lower than a preset threshold, the driving condition of the vehicle is acceleration, the driving condition of the vehicle is overload braking, and the like.
After the electronic control unit determines the running condition of the vehicle, the acquired running condition of the vehicle is judged. When the driving condition satisfies the alert tone output condition, the electronic control unit may perform step 103 to enable the vehicle to emit an alert tone under the driving condition. When the running condition does not satisfy the condition for outputting the warning tone, the electronic control unit may perform, for example, steps S101, and S102 to continue the determination of the running condition of the vehicle.
And S103, controlling the alarm to send out a prompt tone corresponding to the running condition to the outside of the vehicle.
When the driving condition meets the prompt tone output condition, the electronic control unit can control the alarm to send out the prompt tone corresponding to the driving condition to the outside of the vehicle.
For example, in the case of backing up, the driving condition of the vehicle is satisfied, the electronic control unit may control the alarm to emit a warning sound such as a "tic-tic" -or a "caution to safety in backing up" to the outside of the vehicle.
Taking the driving condition meeting the driving condition of the vehicle as an example of turning, assuming that the driving condition of the vehicle acquired by the electronic control unit is a right-turning state, the alarm can be controlled to send out warning sounds such as 'turn right, please pay attention to safety' and the like to the outside of the vehicle. Alternatively, assuming that the driving condition of the vehicle acquired by the electronic control unit is a left-turning state, the alarm may be controlled to emit a warning sound such as "left-turning, please pay attention to safety" to the outside of the vehicle.
For example, the electronic control unit may control the alarm to emit a warning sound of "tic-tic" to the outside of the vehicle, or may emit a warning sound similar to a "sound emitted during driving of a vehicle using fuel as a power source" when the vehicle is running at a low speed where the speed is lower than a preset threshold value.
For example, assuming that a plurality of (two or more) driving conditions of the vehicle all satisfy the corresponding prompt tone output conditions, the electronic control may control the alarm to emit the prompt tone corresponding to the driving condition with the highest priority according to the priorities corresponding to different driving conditions. The priority levels corresponding to the different driving conditions can be preset in the electronic control unit.
Taking the reversing condition, the turning condition and the speed condition of the vehicle as examples, the electronic control unit controls the alarm to send out the priority of the driving condition of the vehicle as the reversing corresponding prompt tone, and the priority of the driving condition of the vehicle as the turning corresponding prompt tone can be larger than the priority of the driving condition of the vehicle as the turning corresponding prompt tone. The running condition of the vehicle sent by the alarm is the priority of the prompt tone corresponding to turning, and the running condition of the vehicle sent by the alarm can be higher than the priority of the prompt tone corresponding to low-speed running with the speed lower than a preset threshold. That is, when the electronic control unit determines that the backing condition and the turning condition of the vehicle and the speed condition all satisfy the prompt tone output condition, the electronic control unit can control the alarm to send out the corresponding prompt tone when the running condition of the vehicle is turning to the outside of the vehicle.
It should be understood that the warning tones corresponding to the different driving conditions may be the same or different. And the content of the prompt tone corresponding to the driving condition is not limited. The content of the above-mentioned respective alert tones is only an example provided in the present application. In specific implementation, the electronic control unit can control the prompt tone sent by the alarm to be other contents.
Optionally, the electronic control unit may control the alarm to stop sending the warning sound corresponding to the driving condition after determining that the driving condition of the vehicle does not satisfy the warning sound output condition.
Alternatively, when the driving condition does not satisfy the condition for outputting the warning tone, the electronic control unit may not perform any operation on the alarm, and return to step S101. Alternatively, the electronic control unit may also transmit the acquired driving condition of the vehicle to an output device (e.g., a display screen), and control the output device to display the driving condition.
Optionally, the electronic control unit and the alarm may be connected through a Controller Area Network (CAN) bus, or may be electrically connected to each other, so that the electronic control unit may control the alarm to emit a warning sound corresponding to a driving condition of the vehicle.
In this embodiment, whether the running condition of the vehicle meets the prompt tone output condition or not is judged, and when the running condition meets the prompt tone output condition, the alarm is controlled to send out a prompt tone corresponding to the running condition to the outside of the vehicle. That is, this application can realize sending corresponding warning sound to the different operating mode of traveling of vehicle through an alarm, compares in current vehicle suggestion method electronic control unit need be connected with a plurality of alarms and bee calling organ, and the method that this application provided has reduced vehicle control circuit's complexity. When the alarm is required to send out corresponding prompt tones aiming at the running working conditions of more types of vehicles, corresponding control logics can be added into the electronic control unit and the existing alarm, so that the flexibility of a vehicle control circuit is improved.
Furthermore, the electronic control unit can also determine the current environment of the vehicle before controlling the alarm to send out the prompt tone to the outside of the vehicle. And then the electronic control unit can judge whether the volume adopted by the alarm is matched with the current environment of the vehicle according to the current environment of the vehicle. If the volume that the alarm adopted does not match with the current environment of place of vehicle, then the electronic control unit can be based on the current environment adjustment alarm that the vehicle is located of vehicle adopted volume to reduce the noise pollution that the above-mentioned alarm sent the prompt tone and cause, perhaps, can reach the effect of suggestion in order to guarantee the prompt tone that the alarm sent. If the volume adopted by the alarm is matched with the current environment of the vehicle, the volume adopted by the alarm does not need to be adjusted.
Alternatively, the current environment of the vehicle may include day or night, for example. For example, the volume of the alarm used by the electronic control unit when the electronic control unit determines that the current environment of the vehicle is daytime can be larger than the volume of the alarm used by the electronic control unit when the electronic control unit determines that the current environment of the vehicle is nighttime, so as to reduce noise pollution caused by the alarm giving out a warning sound.
For example, the electronic control unit may determine the current environment of the vehicle by acquiring the state (on state, or off state) of the vehicle lights of the vehicle, and then determining the current environment of the vehicle according to the state of the vehicle lights. The vehicle lamp may be one or more of vehicle headlights, license plate lamps, night-driving wide lamps, and the like.
Specifically, if the electronic control unit determines that the vehicle lights of the vehicle are in an off state, which indicates that the driver can drive normally without turning on the vehicle lights in the environment, the electronic control unit may determine that the current environment of the vehicle is in the daytime. If the electronic control unit determines that the lamps of the vehicle are in an on state, which indicates that the driver needs to turn on the lamps in the environment to ensure normal driving, the electronic control unit may determine that the current environment of the vehicle is at night.
Alternatively, the electronic control unit may also acquire the current time, and then determine whether the environment in which the vehicle is currently located is day or night according to the current time. For example, between seven and nineteen hours of the day, the electronic control unit may determine that the environment in which the vehicle is currently located is daytime. Between nineteen and seven on the next day, the electronic control unit may determine that the environment in which the vehicle is currently located is night. It should be understood that the electronic control unit may adjust the time period by obtaining the current date and then according to the mapping of the current date to the time period. Alternatively, the time period may be set by the user according to the user's own needs.
Or the electronic control unit can be connected with a light sensor of the vehicle to acquire the intensity of the light of the environment where the vehicle is located, which is acquired by the light sensor. When the intensity of the light is greater than or equal to the first preset threshold, the electronic control unit may determine that the environment in which the vehicle is currently located is daytime. When the intensity of the light is less than the first preset threshold, the electronic control unit may determine that the environment in which the vehicle is currently located is night.
Optionally, the current environment of the vehicle may further include a location of the vehicle, for example. For example, the electronic control unit may further obtain position information of the vehicle to determine a position of an environment where the vehicle is located, and then the electronic control unit may adjust and adjust a volume used by the alarm according to a difference in the position where the vehicle is located. The location may be, for example, a street, a highway, a school, etc. For example, the volume of the alarm when the electronic control unit determines that the current position of the vehicle is a street may be greater than the volume of the alarm when the electronic control unit determines that the current position of the vehicle is a highway, so as to ensure that a prompt sound emitted by the alarm can achieve a prompt effect.
Optionally, the current environment of the vehicle may further include a sound decibel of the environment of the vehicle. For example, the electronic control unit may also obtain a decibel value of the sound of the environment in which the vehicle is located. When the decibel value of the sound of the environment where the vehicle is located is greater than or equal to the second preset threshold value, it indicates that the environment where the vehicle is located is noisy, and a pedestrian (or other animals and the like) may not hear the prompt sound emitted by the alarm of the vehicle. Then, the electronic control unit determines the volume adopted by the alarm when the decibel value of the sound of the environment where the vehicle is located is greater than or equal to the second preset threshold, and the volume adopted by the alarm when the decibel value of the sound of the environment where the vehicle is located is determined to be smaller than the second preset threshold by the electronic control unit, so that the prompt sound emitted by the alarm can achieve the prompt effect.
Furthermore, the electronic control unit can also detect whether the alarm has a fault. And if the alarm fails, outputting alarm failure prompt information to an output device.
Optionally, after the electronic control unit controls the alarm to emit the prompt tone, whether the alarm emits the prompt tone corresponding to the driving condition may be detected. Specifically, the electronic control unit can collect the prompt tone sent by the alarm, and then judge whether the content of the prompt tone sent by the alarm is the same as the content of the prompt tone corresponding to the running condition. If the content of the prompt tone sent by the alarm is the same as that of the prompt tone corresponding to the driving condition, the alarm sends out correct prompt tone according to the indication of the electronic control unit, namely the electronic control unit can determine that the alarm does not have a fault. If the content of the prompt tone sent by the alarm is different from the content of the prompt tone corresponding to the running condition, the fact that the alarm does not send the prompt tone corresponding to the running condition is indicated, and the electronic control unit can determine that the alarm breaks down.
Or, if the electronic control unit does not acquire the warning sound sent by the alarm after the electronic control unit controls the alarm to send the warning sound for a period of time, which indicates that the alarm does not send the warning sound, the electronic control unit may determine that the alarm is out of order.
Optionally, the electronic control unit may also supply power to the alarm. Under the implementation mode, the electronic control unit can judge whether the alarm breaks down or not by detecting whether a loop between the alarm and the electronic control unit is conducted or not. If the electronic control unit detects that the loop between the alarm and the electronic control unit is on, the electronic control unit may determine that the energized circuit of the alarm is not malfunctioning. If the electronic control unit detects that the circuit between the alarm and the electronic control unit is not open, the electronic control unit may determine that the energized circuit of the alarm may fail.
After determining that the alarm is out of order, the electronic control unit may output a message indicating that the alarm is out of order to the output device. The output device may be, for example, a voice broadcasting device, or a display device (e.g., a display screen). Taking the above output device as a voice broadcasting device as an example, after the alarm is determined to have a fault, the electronic control unit may output a prompt message of the fault of the alarm to the voice broadcasting device, and control the voice broadcasting device to send out prompt tones such as "alarm fault, prompt maintenance in time", and the like. Alternatively, for example, when the output device is a display device, after the alarm is determined to be out of order, the electronic control unit may output a prompt message indicating the alarm is out of order to the display device, and control the display device to display, for example, "alarm is out of order, please maintain in time! "etc., or in other forms to display a reminder of the alarm failure.
By taking the example that the alarm can give out the prompt tone corresponding to the reversing running condition, the prompt tone corresponding to the turning running condition and the prompt tone corresponding to the low-speed running condition, fig. 3 is a schematic flow diagram of another vehicle prompting method provided by the application.
As shown in fig. 3, the electronic control unit of the vehicle may acquire a gear signal, a vehicle speed signal, a steering signal, and a lamp signal of the vehicle. Optionally, the electronic control unit may be connected to a gear sensor, a vehicle speed sensor, a steering sensor, and a vehicle lamp of the vehicle to obtain a gear signal, a vehicle speed signal, a steering signal, and a vehicle lamp signal of the vehicle.
The electronic control unit may then determine the driving condition of the vehicle based on the above-mentioned signals. Specifically, the electronic control unit can judge whether the vehicle is in a reverse running working condition, a turning running working condition or not, a low-speed running working condition or not and whether the environment where the vehicle is located is day or night based on the signals.
If the electronic control unit determines that the vehicle is in the reverse driving working condition, the electronic control unit can control the alarm to send a reverse prompting sound corresponding to the reverse driving working condition, such as 'please pay attention to safety in the process of reversing the vehicle'.
If the electronic control unit determines that the vehicle is in the turning running condition, the electronic control unit can also acquire whether the vehicle turns right or left according to the steering signal. Assuming that the vehicle turns right, the electronic control unit may control the alarm to emit a turning prompt tone corresponding to the turning driving condition, such as "the vehicle turns right, please pay attention to safety" or the like.
If the electronic control unit determines that the vehicle is in a low-speed driving condition, the electronic control unit may control the alarm to emit a low-speed prompt sound corresponding to the low-speed driving condition, such as 'tic-tic'.
If the electronic control unit determines that the vehicle lights are in the off state, the electronic control unit may determine that the environment in which the vehicle is located is daytime. The electronic control unit can then determine whether the volume used by the alarm matches the environment of the vehicle during the day. If the sound volume is matched with the preset volume, the volume adopted by the alarm does not need to be adjusted. If not, the electronic control unit adjusts the volume adopted by the alarm to be matched with the environment of the vehicle in the daytime so as to ensure that the prompt tone sent by the alarm can achieve the prompt effect.
If the electronic control unit determines that the vehicle lights are in an on state, the electronic control unit may determine that the environment in which the vehicle is located is at night. The electronic control unit can then determine whether the volume used by the alarm matches the vehicle's environment at night. If the sound volume is matched with the preset volume, the volume adopted by the alarm does not need to be adjusted. If not, the electronic control unit adjusts the volume adopted by the alarm to be matched with the environment of the vehicle at night so as to reduce noise pollution caused by the alarm giving out prompt tones.
