In the antiskid method provided by the embodiment of the present invention, first, in the running process of the vehicle, the running state information of the target tire is acquired. And based on the running state information, whether the vehicle is in a braking state or not and whether the vehicle starts a braking spray mode or not are judged. And then, if the brake spraying mode is started and the vehicle is in a brake state, acquiring a first control signal corresponding to the brake state. The first control signal includes: a first time period and a first spray flow rate for spraying the anti-skid agent to the target tire. And sending a first control signal to spraying equipment corresponding to the target tire, so that the spraying equipment sprays the anti-skid agent to the target tire by adopting a first spraying flow rate within a first spraying time period. The driver starts the brake spraying mode under the condition that the friction force of the tire needs to be increased, and the anti-skid agent is sprayed to the target tire to increase the friction force of the target tire by braking each time through the method. Before sideslip occurs, corresponding processing is carried out on the target tire in advance, sideslip risk avoidance is facilitated, and safety in the driving process is improved. And moreover, the antiskid capacity of the vehicle can be adjusted in time by opening and closing the brake spraying mode, and the response capacity to the sudden special road conditions is improved.
Optionally, the driving state information may be acquired in a plurality of manners, for example: the driving state information is acquired by a vehicle body electronic stability system and is transmitted to a driving computer through a vehicle communication bus, such as a CAN bus. The electronic vehicle body stabilizing system and the anti-lock braking system work cooperatively to acquire a sideslip signal from a wheel speed sensor for detecting a target tire, wherein the sideslip signal is a wheel gap signal detected by the wheel speed sensor, and the electronic vehicle body stabilizing system analyzes the wheel gap signal to judge whether sideslip occurs. Similarly, the wheel gap signal is detected through the wheel speed sensor, and the braking state can be obtained.
Optionally, the spraying device may be various, for example: anti-slip agent spray motors, and the like.
Optionally, the manner of obtaining the above-mentioned brake spray mode may be various, for example: the method comprises the steps of obtaining a first voice control signal through man-machine interaction equipment of a vehicle, and converting the first voice control signal into a first control signal. And a brake spraying mode can be set and started through the intelligent control panel.
Optionally, the brake spray mode may be various, for example: the above-mentioned brake sprays the mode and still includes: a normal brake spray mode or an advanced brake spray mode. The common brake spraying mode sends a preset control signal to the spraying equipment corresponding to the target tire, the preset control signal comprises preset time and preset spraying flow for spraying the anti-skid agent to the target tire, the preset time and the preset spraying flow can be adjusted within a calibration range, the common brake spraying mode is adopted, the load of a running computer can be reduced, when the electronic stability system of the automobile body detects that the automobile brakes, the spraying equipment performs spraying operation according to the preset time and the preset spraying flow, the surplus of the anti-skid agent can be less by adjusting the preset spraying flow, and when the anti-skid agent cannot be supplemented immediately, the preset spraying flow is reduced appropriately, the anti-skid performance is reduced appropriately within a safety range, the anti-skid function of the automobile can be maintained for a longer time, and the anti-skid capability of the automobile for long-rain and snow special road conditions can be enhanced. The advanced brake spraying mode calculates through parameters related to the brake state to obtain a calculated flow value, and continuously sprays the target tire according to the calculated flow value in the brake duration. Compared with the common brake spraying mode, the advanced brake spraying mode has better anti-skid performance and more accurate flow control of the anti-skid agent, but the anti-skid agent is more easily exhausted under the condition that the residual quantity of the anti-skid agent is insufficient, so that safety accidents such as sideslip and the like are easily caused under the condition that the vehicle is not protected after the anti-skid agent is exhausted in the long-term driving process. According to specific application conditions, relevant personnel need to correspondingly adjust the scene, and flexibly respond to various scenes.
Alternatively, the target tire may be various, for example: the target tire may be all tires in the vehicle, may be a driving wheel of the vehicle, and the driving wheel may be a front wheel or a rear wheel. For a typical four-wheeled small vehicle, such as: the spraying of the anti-skid agent can be carried out on all tires for household cars, sports cars and the like. However, for large load-carrying vehicles, such as dump trucks, haul trucks, off-road trucks, the variety of trucks manufactured for particular needs includes: airport ferry vehicles, fire trucks, ambulances, tank trucks, container tractor trucks and the like, wherein the load carrying capacity of the load carrying vehicles has great difference according to different practical application scenes, and the load carrying capacity directly influences the number of tires. The number of tires of a vehicle with large load capacity is large, and a truck with the load of 1 ton to 8 tons generally has 4 to 6 tires; the truck with the load of 8-25 tons has 12 tires, the front vehicle head has 4 tires, and the rear tractor has 8 tires; trucks carrying 25 to 31 tonnes have 14 tires, 4 front noses, 10 rear tractors, etc. in sequence. Therefore, using all tires in a vehicle as target tires results in too fast a consumption of anti-slip agent, requiring a large anti-slip agent filling tank, which puts a burden on the vehicle. In order to solve the problems, the driving wheels and part of driven wheels of the vehicle can be used as target tires, so that the adjustment can be flexibly carried out according to the application condition of the specific vehicle, the consumption of the anti-skid agent and the anti-skid performance are in proper balance, the application scenes and the flexibility of the anti-skid method are increased, and the limitation is reduced.
Alternatively, the anti-slip agent may be a plurality of, for example: the liquid or glue solution formed by raw materials with anti-skid function, such as rubber (natural rubber or synthetic rubber), silicone oil or polyurethane compound, can be added with aerosol for spraying.
In an optional embodiment, the method further includes: judging whether the state of the target tire is a sideslip state or not; if the state of the target tire is the sideslip state, acquiring a second control signal corresponding to the sideslip state, wherein the second control signal comprises a second spraying time length and a second spraying flow rate for spraying the anti-skid agent to the target tire; and sending the second control signal to spraying equipment corresponding to the target tire, wherein the spraying equipment is used for spraying the anti-skid agent to the target tire based on the second spraying time and the second spraying flow.
It can be understood that the vehicle antiskid performance is not good due to the fact that the brake spraying mode cannot be started timely due to the fact that related personnel misjudge the driving environment. The method includes the steps that after the sideslip state is detected, the vehicle automatically responds, firstly, whether the state of a target tire is in the sideslip state or not is judged based on running state information, and if the state of the target tire is in the sideslip state, a second control signal corresponding to the sideslip state is acquired. The second control signal includes a second spraying time period and a second spraying flow rate for spraying the anti-skid agent to the target tire. And then, sending a second control signal to the spraying equipment corresponding to the target tire. And spraying the anti-skid agent to the target tire by adopting a second spraying flow rate within a second spraying time period by the spraying equipment.
Optionally, the braking depth information may be obtained in a variety of manners, for example: the brake assembly equipment detects stroke information of a brake pedal to represent brake depth information, and the brake depth information is obtained through a driving computer. According to the specific vehicle type difference, a sensor or other sensing equipment for detecting a brake pedal is arranged, and a driving computer acquires brake depth information, and the method belongs to the protection scope of the invention.
Optionally, the first time threshold may be multiple, for example: the first duration threshold is used for measuring the antiskid effect of the vehicle, for the convenience of understanding, specific examples are carried out, the condition that the road surface is slightly iced or the snow is usually appeared in winter in the north, the vehicle also has a brake state in normal driving, and when the current antiskid effect can meet the vehicle requirement, the brake duration generally cannot exceed the first duration threshold. The first time constant threshold value can be calibrated and corrected through experiments based on different vehicle types.
It should be noted that the state of the target tire does not completely coincide with the state of the vehicle, and specific examples thereof are given for easy understanding, for example: for a common household vehicle, such as a front-wheel drive four-wheel vehicle, when the sideslip of the whole vehicle is detected, the front wheel slips, the rear wheel slips or both the front wheel and the rear wheel slip under possible conditions. The sideslip state of the target tire is obtained through the vehicle body electronic stability system, and the sideslip is generated by spraying, if the front wheel is detected to be in the sideslip state from the running state information, the whole vehicle sideslips, but the rear wheel is in a normal state, at the moment, the second control signal is sent to the spraying equipment corresponding to the front wheel, the spraying is carried out based on the second control signal, and the friction force of the front wheel to the ground is improved. In the above example, it can be seen that different tires of the vehicle may be in different states, but any one of the tires may slip, which may cause the vehicle to slip. According to the running state information, the tires which sideslip purposefully spray, and the method is favorable for avoiding unnecessary waste of the anti-skid agent on the premise of ensuring the anti-skid capacity.
In an optional embodiment, the method further includes: if the brake duration reaches the first time threshold, determining a second calculated flow based on the brake depth information and a second spray algorithm; and obtaining the first control signal based on the brake duration and the second calculated flow, wherein the first spraying duration is the brake duration, and the first spraying flow is the second calculated flow.
It can be understood that the antiskid requirement cannot be met in the brake spraying mode, at this time, the brake duration of the vehicle will exceed the first duration threshold, and in order to further enhance the antiskid capability, first, after it is determined that the brake duration reaches the first duration threshold, the second calculated flow is determined based on the brake depth information and the second spraying algorithm. And the first spraying duration is the brake duration, and the first spraying flow is the second calculated flow, so that a first control signal is obtained.
It should be noted that, when the braking duration reaches the first duration threshold, it is considered that the current antiskid capability has not yet reached the vehicle requirement, and for convenience of understanding, specific examples are given, for example: when sideslip occurs on an icy road, a driver can continuously step on the brake for the purpose of controlling the vehicle until the vehicle is controlled, the brake duration in the process is generally obviously longer than a normal brake state, namely the brake duration is not shorter than a first duration threshold value, the vehicle is considered to have a risk of being out of control, the antiskid capacity needs to be improved, and a second spraying algorithm is correspondingly adopted to obtain a second calculated flow. Another example is: the vehicle descends on a long slope in rainy and snowy weather, the vehicle is in a braking state for a long time, the vehicle is not in a sideslip state at the moment, the driver starts a braking spraying mode for insurance, the braking duration exceeds a first duration threshold value at the moment, the sideslip is not out of control, the speed of the vehicle on the downhill slope easily reaches a relatively fast range, the potential safety hazard exists under the condition that the adhesive force of the tire is insufficient, and the second spraying algorithm with higher anti-skidding capacity is adopted, so that the risk can be avoided in advance.
It should be noted that, since the second spraying algorithm is an enhancement algorithm performed to increase the flow rate of the anti-slip agent in the case that the first spraying algorithm cannot meet the requirement, that is, the duration of braking reaches the first time threshold. Therefore, although the second calculated flow and the first calculated flow are both calculated values, the first spraying algorithm and the second spraying algorithm are set, so that the second calculated flow obtained correspondingly is certainly greater than the first calculated flow under the condition that the braking depth is the same, and the anti-skid capacity is enhanced.
In an alternative embodiment, before obtaining the running state information of the target tire during running of the vehicle, the method further includes: acquiring a manual control signal and a manual duration corresponding to the manual control signal; and controlling the spraying equipment to spray the anti-skidding agent to the target tire by adopting a preset third spraying flow based on the manual duration.
It can be understood that in actual driving, the driver judges that antiskid needs to be carried out, but the brake spraying mode is not considered to be required to be started, manual control is carried out for temporary coping, and a manual control signal and a corresponding manual duration are acquired firstly. And then, on the basis of the manual duration, adopting a preset third spraying flow to control the spraying equipment to spray the target tire.
Optionally, the above manner of acquiring the manual control signal may be various, for example: and acquiring a second voice control signal through the human-computer interaction equipment of the vehicle, and converting the second voice control signal into a manual control signal. And a manual starting button can be arranged on the steering wheel, so that a driver can conveniently send a manual control signal in time when finding out an emergency, and the operation can be finished without interfering normal driving behaviors.
It should be noted that, can make the driver have the anti-skidding ability of autonomous control through manual control, in the state of non-sideslipping and non-brake state, in case the driver finds the not good or presbying that the place ahead gets into the vehicle and sideslips the high emergence section of risk subjectively, can prevent smooth emergency treatment through sending manual control signal, control manual duration length according to specific demand for the anti-skidding ability size of control vehicle.
In an optional embodiment, before sending the first control signal to the spraying device corresponding to the target tire, the method further includes: acquiring the flow in a spray pipeline corresponding to the spray equipment, wherein the spray pipeline is used for connecting an anti-skid agent filling tank and a spray nozzle, and the spray nozzle is used for spraying the anti-skid agent to the target tire; judging whether the flow is smaller than a preset flow or not; and if the flow is smaller than the preset flow, sending a first prompt signal to the human-computer interaction equipment of the vehicle, wherein the first prompt signal is used for prompting the anti-skid agent flow alarm.
It can be understood that, in order to avoid the problems of damage to the spraying pipeline or blockage of the spraying nozzle, etc., the condition that the spraying equipment works but the target tire cannot be actually sprayed by the anti-skid agent is caused, so that the damage to the spraying equipment or the waste of the anti-skid agent is caused. Before sending a first control signal to spraying equipment corresponding to a target tire, firstly, acquiring the flow in a spraying pipeline, after confirming that the flow is smaller than a preset flow, regarding the situation that normal spraying cannot be carried out, sending a first prompt signal to man-machine interaction equipment of a vehicle, and prompting a driver to alarm when the flow of an anti-skid agent is currently positioned.
Optionally, there are various ways to obtain the flow, for example: and a flow meter is arranged in the spraying pipeline, and the flow signal in the flow meter is acquired and transmitted to a traveling crane computer.
Optionally, the first prompt signal may be of multiple types, for example: after the obtained flow is smaller than the preset flow, the spraying nozzle is prompted to be blocked by foreign matters, or the spraying pipeline is prompted to be broken, and the anti-skid agent can normally reach the target tire under the above conditions.
In an optional embodiment, before sending the first control signal to the spraying device corresponding to the target tire, the method further includes: acquiring the liquid level height in the anti-skid agent filling tank; judging whether the liquid level height is lower than a preset height or not; and if the liquid level height is smaller than the preset height, sending a second prompt signal to the human-computer interaction equipment of the vehicle, wherein the second prompt signal is used for prompting the anti-skid agent storage amount alarm.
It can be understood that when the demand of long-time antiskid running is avoided, the vehicle runs on a rainy and snowy road surface without protective measures due to the lack of the anti-slip agent, so that the potential safety hazard problem is caused, the residual amount of the anti-slip agent needs to be detected, the anti-slip agent is considered to need to be supplemented after the liquid level is confirmed to be lower than the preset height by acquiring the liquid level in the anti-slip agent filling tank, a second prompt signal is sent to human-computer interaction equipment of the vehicle, and the second prompt signal is used for prompting the anti-slip agent storage amount alarm.
Alternatively, the liquid level may be obtained in various manners, for example: a liquid level height sensor is arranged in the anti-skid agent filling tank, so that a liquid level height signal is obtained and transmitted to a traveling crane computer.
Based on the above embodiments and alternative embodiments, the present invention provides an alternative implementation manner, which is specifically exemplified for easy understanding, for example: when the vehicle only sideslips, when the wheel speed sensor identifies that the vehicle sideslips, the sideslip signal is transmitted to the vehicle body electronic stabilizing system, and the vehicle body electronic stabilizing system transmits the sideslip signal to a driving computer. And the traveling crane computer receives the sideslip signal and then performs automatic antiskid response, and at the moment, the traveling crane computer sends a second control signal to the spraying equipment. After the spraying equipment is started, the anti-skid agent in the anti-skid agent filling tank is pumped to the spraying nozzle through the spraying pipeline and is sprayed out from the spraying nozzle after reaching a certain pressure. The spray nozzle uniformly sprays the anti-skid agent to the target tire, thereby achieving the purposes of increasing the friction force of the tire and improving the anti-skid performance.
When the conditions such as weather of a special road section are suddenly sent in driving, when a driver self-identifies that the anti-skid performance of the vehicle needs to be increased, a manual starting button on the multifunctional steering wheel can be manually pressed, or a voice command is input through the intelligent control panel, so that manual control is started. And transmitting the manual control signal to a traveling crane computer, and sending the control signal to the spraying equipment by the traveling crane computer based on the preset spraying flow and the manual duration. After the spraying equipment is started, the anti-skid agent in the anti-skid agent filling tank is pumped to the spraying nozzle through the spraying pipeline to reach a certain pressure and is sprayed out from the spraying nozzle. The spray nozzle uniformly sprays the anti-skid agent to the target wheel, thereby achieving the purpose of increasing the friction force of the tire and improving the anti-skid performance.
When the automobile is driven in the weather of special road conditions, a driver can enter a brake spraying mode through the intelligent control panel or input a voice command. At the moment, in the driving process, the brake signal can be transmitted to the electronic stability system of the vehicle body through the wheel speed sensor every time, and the electronic stability system of the vehicle body transmits the sideslip signal to the traveling computer. And after receiving the sideslip signal, the traveling computer starts a brake spraying mode, and sends a first control signal to the spraying equipment to perform spraying, namely, the spraying of the anti-skid agent is finished once every braking.
In addition, when each part breaks down after the antiskid system is started, the traveling crane computer can identify the fault part through a corresponding sensor, such as an electric signal sent by a flowmeter, and prompt alarm information in an intelligent control panel. When the liquid level of the anti-skid agent filling tank reaches the limit value, the liquid level sensor sends a liquid level height signal to the traveling crane computer, the traveling crane computer transmits the signal to the intelligent control panel, and the liquid level alarm signal can be displayed on the intelligent control panel so as to prompt a driver to pay attention to the liquid level of the anti-skid agent.
At least any one of the following effects is achieved by the above alternative embodiment: the antiskid mode is that the antiskid spray agent is used for increasing the friction force of the automobile tire so as to increase the antiskid performance of the automobile tire, the antiskid capability can be improved without stopping the automobile in the driving process, the antiskid is started at any time in different environments, time and scenes, and the quick switching of the antiskid performance requirements of the tire on an easy-to-slide road surface and a normal road surface is realized. The device has two control modes of manual operation and automatic operation. The antiskid can be opened in various ways, the normal driving process is not influenced, and the antiskid device is combined with the human-computer interaction device and can be started by intelligent voice.
