The specific embodiment of the system for controlling the accelerator stepping by mistake is basically the same as the following embodiments of the method for controlling the accelerator stepping by mistake, and the detailed description is omitted here.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of an accelerator step-by-step control method according to the present invention, wherein the accelerator step-by-step control method includes the following steps:
step S10, monitoring the opening degree of an accelerator pedal;
the method shown in the present embodiment may be applied to an electronic control unit of an automobile, which may monitor the corresponding opening degree of an accelerator pedal when a driver adjusts the opening degree of the accelerator pedal by stepping on the accelerator pedal, and adjust the power output of an engine according to the opening degree of the accelerator pedal. The electronic control unit can trigger a corresponding switch on the automobile to generate an opening instruction through a driver when the function of controlling the accelerator to be stepped on by mistake is realized, and the electronic control unit can open the accelerator control mode to be stepped on by mistake when receiving the opening instruction, and can also be set to automatically open the accelerator control mode to be stepped on by mistake in the running process of the automobile without manual setting of the driver. Under the control mode that the accelerator is stepped on by mistake, the electronic control unit can monitor the opening of an accelerator pedal of the automobile in real time so as to carry out safety processing when a driver steps on the accelerator by mistake and avoid vehicle accidents.
Step S20, stopping adjusting the power output of the engine when the opening of the accelerator pedal reaches a preset calibration condition;
the electronic control unit is internally pre-stored with corresponding calibration conditions, and in the process of monitoring the opening degree of the accelerator pedal in real time by the electronic control unit, if the opening degree of the accelerator pedal monitored by the electronic control unit meets the calibration conditions, the driver can be determined to make an operation of stepping on the accelerator by mistake. After the electronic control unit determines that the driver steps on the accelerator by mistake, the electronic control unit can control an engine throttle valve of the automobile in time to not respond to the change of the opening degree of the accelerator pedal, namely, the electronic control unit controls the engine not to adjust power output when the driver steps on the accelerator by mistake, so that the rapid increase of the speed of the automobile is avoided.
It should be noted that, when the driver may mistakenly depress the accelerator while the vehicle is in a running state, the electronic control unit stops adjusting the power output of the engine, which means that the power output of the engine is not increased to accelerate the vehicle, but the power output before the mistaken accelerator depression is maintained, so that the vehicle continues to run at the original speed. For example, in an idle state of a vehicle, when a driver performs a false accelerator operation, the torque output of the engine is not increased, but the idle state is maintained.
And step S30, receiving a closing instruction triggered by a driver, and according to the closing instruction, regaining the opening degree of the accelerator pedal after the opening degree of the accelerator pedal returns to zero so as to adjust the power output of the engine.
After the driver generates a closing instruction of the accelerator mistaken-stepping control by triggering a corresponding switch on the automobile, the electronic control unit can receive the closing instruction and close the accelerator mistaken-stepping control function. It can be understood that, when the driver closes the accelerator mis-stepping control function, if the driver still keeps the accelerator pedal stepping state, the throttle valve of the engine after closing the function will immediately respond to the opening degree of the accelerator pedal and provide corresponding power output, at this moment, the automobile will rapidly accelerate at the moment of closing the accelerator mis-stepping control function, and accidents are very easy to cause. In order to avoid that the driver closes the accelerator mistaken-stepping control function and simultaneously causes the automobile to accelerate suddenly, after the driver triggers a closing instruction, when the opening degree of the accelerator pedal is not zero, the electronic control unit does not respond to the opening degree of the accelerator pedal, namely, the driver closes the accelerator mistaken-stepping control function after stepping on the accelerator pedal, and the automobile does not accelerate suddenly. After the electronic control unit closes the accelerator mistaken-stepping control function, the opening degree of the accelerator pedal needs to be reset to zero when the opening degree of the accelerator pedal is detected, namely, the opening degree of the accelerator pedal is obtained again and the engine is controlled to output corresponding power after the driver releases the accelerator pedal. That is, after the driver steps on the accelerator pedal and closes the accelerator mis-stepping control function, the driver needs to release the accelerator pedal to return the opening of the accelerator pedal to zero, and then can step on the accelerator pedal again to control the automobile to move forward.
If the driver does not depress the accelerator pedal when the accelerator mis-depression control function is turned off, the opening degree of the accelerator pedal is always zero, and the condition that the opening degree of the accelerator pedal is returned to zero is also met. At the moment, the driver can control the automobile to run by stepping on the accelerator pedal again.
In the present embodiment, the electronic control unit is capable of monitoring the opening degree of the accelerator pedal depressed by the driver in real time. When the electronic control unit detects that the opening of the accelerator pedal meets the preset calibration condition, the electronic control unit can judge that the driver has mistakenly stepped on the accelerator, and at the moment, the electronic control unit can control the engine to not respond to the mistakenly stepped on the accelerator, namely, the power output of the engine is not changed after the driver mistakenly steps on the accelerator, and the original power output is still kept. When the driver closes the accelerator mistaken-stepping control function, the electronic control unit can adjust the power output of the engine again according to the opening degree of the accelerator pedal after detecting the opening degree zero crossing point of the accelerator pedal, so that the rapid acceleration of the automobile at the moment of closing the function is avoided. Whether the driver has the accelerator mistaken stepping operation or not is detected by setting a calibration condition on the electronic control unit, so that the automobile can be prevented from being accelerated suddenly when the driver mistakenly steps on the accelerator, and the actual damage to the unavoidable automobile accident can be reduced by limiting the power output of the engine.
Further, referring to fig. 3, fig. 3 is a schematic flowchart of a second embodiment of the method for controlling an accelerator pedal being stepped on by mistake according to the present invention, and based on the embodiment shown in fig. 2, the step S20, when the opening degree of the accelerator pedal reaches a preset calibration condition, the step of stopping adjusting the power output of the engine includes:
step S21, monitoring the opening increment of the accelerator pedal within a preset time interval;
and step S22, stopping adjusting the power output of the engine when the opening increment of the accelerator pedal reaches a preset threshold value in a preset time interval.
In this embodiment, a preset scalar is stored in the electronic control unit, that is, a preset time interval T is stored in milliseconds. When the electronic control unit monitors that the opening of the accelerator pedal is increased in a certain time period with the duration of T and the opening increment reaches a preset opening threshold, the electronic control unit indicates that a driver greatly steps on the accelerator pedal in a very short time, and when the driver starts an accelerator mis-stepping control function, the electronic control unit can judge the action of greatly stepping on the accelerator pedal as a mis-stepping action and does not adjust the power output of the engine. It is understood that the preset time interval T may be a small amount of time to determine whether the driver's momentary throttle application is a false application. The preset opening threshold value can be 90% of the opening of the accelerator pedal, when the opening of the accelerator pedal reaches 90%, it can be determined that the driver steps on the accelerator pedal to the bottom, and the abnormal behavior is judged to be the mistaken stepping operation of the accelerator.
Further, referring to fig. 4, fig. 4 is a schematic flowchart of a third embodiment of the method for controlling an accelerator pedal being stepped on by mistake according to the present invention, and based on the embodiment shown in fig. 3, before the step of stopping adjusting the power output of the engine when the opening increment of the accelerator pedal reaches the preset threshold in the preset time interval in step S22, the method further includes:
step S40, detecting whether an obstacle exists in the moving direction of the automobile, and acquiring the current speed of the automobile;
in step S22, when the opening increment of the accelerator pedal reaches the preset threshold value within the preset time interval, the step of stopping adjusting the power output of the engine further includes:
and step S221, stopping adjusting the power output of the engine when the opening increment of the accelerator pedal reaches a preset threshold value in a preset time interval, an obstacle exists in the moving direction of the automobile, and the current speed of the automobile is lower than a preset speed.
In this embodiment, the vehicle is further provided with a camera for detecting whether an obstacle exists in the moving direction of the vehicle. When the automobile moves forwards or backwards, the camera at the front part or the rear part of the automobile can shoot the moving direction of the automobile and identify whether an obstacle exists in the moving direction. Preferably, the automobile is preset with a warning distance, and the camera only identifies whether an obstacle exists in the warning distance in the moving direction. The electronic control unit can also acquire the current speed of the automobile. When the electronic control unit detects that the opening increment of the accelerator pedal in a preset time interval reaches a preset threshold value, namely, a driver steps on the accelerator pedal instantly and greatly, the current speed of the automobile is lower than the preset speed, and an obstacle exists in the moving direction of the automobile, the electronic control unit can determine that the driver steps on the accelerator pedal mistakenly in a low-speed state, and the automobile can collide with the obstacle when accelerating suddenly. At the moment, the electronic control unit can stop regulating the power output of the engine according to the opening degree of the accelerator pedal, namely, the situation that the driver mistakenly steps on the accelerator to cause the automobile to suddenly accelerate and bump into an obstacle is avoided.
Further, with reference to fig. 4, an alarm is disposed inside the automobile, and after the step S221, when the opening increment of the accelerator pedal reaches a preset threshold value within a preset time interval, an obstacle exists in the moving direction of the automobile, and the current speed of the automobile is lower than a preset speed, the step of stopping adjusting the power output of the engine further includes:
and step S23, controlling the alarm to give out an audible alarm prompt to remind the driver of mistakenly stepping on the accelerator pedal.
In this embodiment, the inside siren that can send the sound suggestion that is provided with of car, detects driver's accelerator pedal, the current speed of a motor vehicle that steps on in the twinkling of an eye by a wide margin at the electronic control unit, and when having the barrier in the moving direction of car, can control the siren and send the sound warning suggestion to remind driver's its operating behavior of stepping on accelerator pedal by mistake, so that the driver in time handles, avoids taking place the vehicle accident.
Further, referring to fig. 5, fig. 5 is a schematic flow chart of a fourth embodiment of the accelerator step-by-step control method according to the present invention, based on the embodiment shown in fig. 2, the automobile is provided with an accelerator step-by-step control mode display lamp inside, and after the step of monitoring the opening degree of the accelerator pedal in step S10, the method further includes:
and step S50, turning on an accelerator mistaken-stepping control mode display lamp to remind a driver that the accelerator mistaken-stepping control mode is turned on.
In this embodiment, a switch display lamp of the accelerator miss-stepping control mode may be disposed inside the automobile. When the accelerator is not turned on in the mistaken stepping control mode, the display lamp does not emit light for display. When the accelerator mistaken-stepping control function is started, the electronic control unit can control the display lamp to emit light for displaying so as to remind a driver that the accelerator mistaken-stepping control mode is started. It should be noted that the switch display lamp in the accelerator miss-stepping control mode may be disposed in an instrument panel inside the automobile. The switch display lamp can be arranged on the automobile machine of the automobile when the instrument panel of the automobile is designed to be fully loaded. Preferably, an entity button can be further arranged in the automobile, a driver or an in-automobile person can realize the opening and closing of the accelerator mistaken-stepping control mode by triggering the entity button, the entity button can be covered on a switch display lamp of the accelerator mistaken-stepping control mode, and the in-automobile person can check the luminous display state of the switch display lamp through the entity button, so that the opening state of the accelerator mistaken-stepping control mode is determined.
It can be understood that, the accelerator step-by-step control mode display lamp may also be in a light-emitting state to indicate that the accelerator step-by-step control mode is not turned on, and a non-light-emitting state to indicate that the accelerator step-by-step control mode is turned on, which is not limited herein.
Further, referring to fig. 6, fig. 6 is a schematic flowchart of a fifth embodiment of the method for controlling an accelerator pedal being stepped on by mistake according to the present invention, based on the embodiment shown in fig. 2, in step S20, when the opening degree of the accelerator pedal reaches a preset calibration condition, the step of stopping adjusting the power output of the engine further includes:
step S61, when the opening degree of the accelerator pedal reaches a preset calibration condition, acquiring the current automobile gear of the automobile;
step S62, when the current gear is a reverse gear, stopping adjusting the power output of the engine and controlling the brake system of the automobile to brake emergently;
and step S63, when the current gear is the forward gear, stopping adjusting the power output of the engine and controlling the engine to maintain the current power output to keep the current vehicle speed.
In this embodiment, the electronic control unit may further obtain the current driving gear of the vehicle when detecting that the opening degree of the accelerator pedal reaches the preset calibration condition. When the automobile is in a reverse gear currently, the automobile is indicated to run backwards, and when the electronic control unit detects that the accelerator is mistakenly stepped on by a driver, the electronic control unit not only stops adjusting the power output of the engine, but also controls the brake system to execute brake operation so as to prevent the automobile from colliding with other objects in the process of backing. When the automobile is in a forward gear, the electronic control unit does not adjust the power output of the engine when detecting that the driver mistakenly steps on the accelerator, but controls the engine to continuously keep the current torque for power output so as to keep the current speed, so that the situation that people in the automobile are injured due to sudden deceleration of the automobile when the automobile runs at a high speed is avoided, and meanwhile, the rear-end collision accident caused by sudden deceleration of the front automobile is avoided.
Further, in other embodiments, based on the embodiments shown in fig. 2 to fig. 6, an accelerator mistaken-stepping control switch may be further disposed in the center console area of the automobile, and the driver may generate an opening instruction or a closing instruction by triggering the accelerator mistaken-stepping control switch. It can be understood that the accelerator mistaken-stepping control switch is arranged in the center console area, and the copilot and the rear seat personnel can also control the opening and closing of the accelerator mistaken-stepping control mode by triggering the control switch.
In addition, the invention also provides a computer readable storage medium, on which the accelerator mistaken-stepping control program is stored.
