Detailed Description
The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the invention are shown in the drawings.
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
In the prior art, pressure and speed information of a driver stepping on an accelerator pedal are collected through a sensor to judge whether the accelerator is stepped on by mistake, but different drivers have different driving styles, and the pressure threshold value and the speed threshold value of the accelerator pedal are set, so that the requirements of all people are difficult to meet, and the reliability of the existing accelerator stepping preventing method is insufficient.
Therefore, the embodiment of the application provides a method for preventing mistaken stepping of an oil door, which can avoid the defect of insufficient reliability of the traditional method for preventing mistaken stepping of an accelerator.
In this embodiment, a method for preventing misstepping on an oil gate is provided, and it can be understood that the method for preventing misstepping on an oil gate can be applied to pure electric vehicles, such as pure electric buses, pure electric cars, and the like.
In one embodiment, referring to FIG. 1, a control schematic for an entire vehicle is shown. As shown in fig. 1, the vehicle may include a vehicle controller 110, where the vehicle controller 110 is connected to a vehicle execution module, a switch module 150, a vehicle speed sensor 160, and an accelerator pedal depth sensor 170 through a CAN communication module 120 (a hard wire or the like may be used, which is not limited herein, and is shown in the figure). The execution modules include a brake system 130, a powertrain 140, and the vehicle powertrain 140 may include a motor controller and a motor. It is understood that the vehicle controller 110 may also be connected to an instrument, a horn, etc.
The vehicle speed sensor 160 is a device for detecting the vehicle speed of the vehicle. It will be appreciated that the vehicle speed may vary from vehicle type to vehicle type, configuration of the vehicle, etc., and that the range of vehicle speeds may be [0,140] km/h, for example.
The accelerator pedal depth sensor 170 is a device for detecting a stroke signal of the accelerator pedal. The accelerator pedal depth percentage may be determined according to the stroke signal of the accelerator pedal and the maximum stroke of the accelerator pedal, specifically, accelerator pedal depth percentage=stroke signal of the accelerator pedal/maximum stroke of the accelerator pedal×100%. It will be appreciated that the range of accelerator pedal depth percentages is [0,100% ], the greater the accelerator pedal depth percentage, the greater the travel signal the accelerator pedal is depressed, i.e., the greater the effort required to depress the accelerator pedal, the closer to full throttle.
The meter may be used to display information such as the status of the vehicle. For example, the meter may display a vehicle warning light to alert the driver that an erroneous accelerator pedal is occurring, etc.
The loudspeaker can be used for sending out voice information such as prompt tone or warning tone. It can be appreciated that the horn may be divided into an internal horn and an external horn, for example, the external horn may send out a voice prompting the driver around that the driver has stepped on the accelerator by mistake, and the internal horn may send out a voice warning the driver that the driver has stepped on the accelerator by mistake. Of course, only one horn or no warning or warning horn may be provided, which is not limited herein.
The brake system 130, i.e., a brake system, may generally include a hand brake and a foot brake (accomplished by a brake pedal) to enable a faster drop in vehicle speed to 0.
The power system 140 may include a motor controller and a motor, where the motor controller receives an instruction from the vehicle controller, and the motor controller controls the motor according to the instruction to move and drive the wheels to rotate, so that the power system 140 may accelerate or decelerate the vehicle, where the speed of deceleration is slower than the speed of deceleration of the vehicle by the brake system 130.
The switch module 150 may be connected to the bottommost end of the accelerator pedal, i.e. when the driver steps on the accelerator pedal to the bottommost end, if the driver continues to step on the accelerator pedal with force, the switch module 150 is triggered, and the switch module 150 sends a switch signal to the vehicle controller 110.
The pressure of a driver to an accelerator pedal does not exceed a first accelerator pedal damping force threshold when the accelerator is stepped to the bottommost end during normal running or even overtaking, and the pressure of the driver to the brake pedal can exceed a second accelerator pedal damping force threshold when emergency is met, and according to statistics, the first accelerator pedal damping force threshold can be 150 newtons generally, and the second accelerator pedal damping force threshold can be 300 newtons. FIG. 2 shows a schematic accelerator pedal damping force diagram, wherein when the pressure of the driver stepping on the accelerator pedal is less than the first accelerator pedal damping force threshold, the accelerator pedal stroke increases linearly with the pressure of the accelerator pedal; when the pressure of the driver stepping on the accelerator pedal is larger than the first accelerator pedal damping force threshold value and smaller than the second accelerator pedal damping force threshold value, the stroke of the accelerator pedal is not increased along with the pressure increase of the accelerator pedal, and the driver is given the feeling that the accelerator pedal is stepped to the bottommost end; when the driver mistakenly depresses the accelerator pedal as a brake pedal, the pressure of the driver depressing the accelerator pedal exceeds the damping force threshold of the second accelerator pedal, and the accelerator pedal enters a signal triggering area, namely the triggering switch module 150 sends a switch signal to the whole vehicle controller 110.
When the vehicle is running, the whole vehicle controller 110 can judge the driving intention of a driver by collecting signals such as the vehicle speed through the vehicle speed sensor and the accelerator pedal depth of the vehicle through the accelerator pedal depth sensor, and send corresponding control instructions to the driving system according to the judged driving intention, and meanwhile, the whole vehicle controller can also send corresponding control instructions to the instrument, the loudspeaker and the like so as to control the instrument, the loudspeaker and the like. The motor controller obtains electric energy from a battery pack of the vehicle, obtains corresponding current and voltage through self modulation, and controls the rotating speed and torque of the motor to meet the requirements of the whole vehicle controller 110. The motor can drive the wheels to rotate.
Referring to fig. 3, a flow chart of a method for preventing misstepping of a door according to one embodiment of the present application is shown. The method for preventing the accelerator pedal from being stepped on by mistake in the present embodiment may be executed in the vehicle controller 110.
As shown in fig. 3, a method for preventing mistaken stepping on an oil gate includes:
s310, determining that the accelerator is stepped by mistake when a switch signal is acquired; the switch signal is sent out through the switch module, the switch module is connected to the bottommost end of the accelerator pedal of the vehicle, and when the accelerator pedal is stepped on to the bottommost end and then is stepped on continuously, the switch module sends out the switch signal.
Specifically, the switching signal may be sent out by the switching module, and optionally, the switching signal may be a high level signal or a low level signal. In general, the switch signal is a low level signal when the normal condition is set, and the switch signal is a high level signal when the pressure of stepping on the accelerator pedal is a second accelerator pedal damping force threshold value, as shown in fig. 4. The switch signal is sent to the whole vehicle controller after being changed into a high-level signal, namely, when the whole vehicle controller receives the switch signal, the driver is judged to have stepped on the accelerator by mistake.
It can be understood that the switch module can also continuously send a switch signal to the whole vehicle controller, and when the switch signal received by the whole vehicle controller changes, namely, the low level signal is changed into the high level signal or the high level signal is changed into the low level signal, the driver can be judged that the accelerator is stepped on by mistake. In general, when the vehicle controller receives a switch signal from a low level signal to a high level signal, it is determined that the driver has stepped on the accelerator by mistake.
S320, determining an adopted execution strategy to control a braking system and/or a power system according to the speed of the vehicle.
Specifically, when the vehicle speed is low, the vehicle speed is often in a complex road condition, or the driver is carrying out complex operations such as reversing, avoiding, and the like, and at the moment, the probability of mistakenly stepping on the accelerator is high, and the hazard is also high. Therefore, when the vehicle speed is low and the accelerator pedal is erroneously stepped, the vehicle control unit controls operations such as emergency stop of the vehicle. When the vehicle speed is higher, the road condition of general vehicle running is better, and the probability of mistakenly stepping on the accelerator is low. Therefore, when the vehicle speed is high and the accelerator is stepped on by mistake, the vehicle control unit controls the vehicle to reduce the speed and the like without emergency stop.
The overall vehicle controller may control the braking system and/or the power system depending on the implementation strategy employed, e.g., may control the braking system such that the vehicle speed drops faster to 0, may control the power system such that the vehicle slows down, etc.
In the method for preventing the mistaken stepping of the accelerator, the whole vehicle controller judges that the mistaken stepping of the accelerator occurs according to the received switch signal, and then the mistaken stepping of the accelerator is completed by combining different execution strategies adopted when different vehicle speeds are combined. The embodiment can meet the requirements of different people and can improve the reliability of preventing the accelerator from being stepped on by mistake.
In one embodiment, determining an execution strategy to be employed by the execution module based on a vehicle speed of the vehicle comprises:
if the speed of the vehicle is less than or equal to the speed threshold, setting the torque of a power system of the vehicle to 0 so as to stop the power output of the vehicle, and controlling a brake system of the vehicle so as to reduce the speed of the vehicle to 0;
if the speed of the vehicle is greater than the speed threshold, the torque of the powertrain of the vehicle is set to 0 to terminate the power output of the vehicle.
Specifically, the vehicle speed threshold may be set empirically or in actual conditions. By way of example, the vehicle speed threshold may be 15km/h.
When the running speed of the vehicle is less than or equal to 15km/h and the driver's accelerator is judged to be stepped on by mistake, the whole vehicle controller CAN set the required torque of the vehicle to 0 and send the required torque to a motor controller in an execution module through a CAN communication module, and the motor controller controls the motor to unload torque to terminate the power output of the vehicle. And meanwhile, the intervention of a braking system is controlled, so that the vehicle is stopped rapidly.
When the running speed of the vehicle is greater than 15km/h, and the driver mistakenly stepping on the accelerator is judged, the whole vehicle controller can set the required torque of the vehicle to be 0, namely, the power output of the vehicle is stopped, the intervention of a braking system is not controlled at the moment, and the accidents such as rear-end collision or instability of the vehicle caused by the fact that a switch module is triggered under the extreme condition in the high-speed running process of the driver are prevented.
It can be understood that when the power output of the vehicle is terminated, the power output of the vehicle can be terminated by adopting a mode that the torque of the motor is slowly unloaded or the feedback torque is increased, so that the smoothness and the economy of the vehicle can be further improved.
In one embodiment, the execution policy employed by the execution module further comprises: and (3) controlling the alarm lamp of the instrument to light and/or controlling the horn to sound.
Specifically, the vehicle controller controls the instrument warning lamp to be on and can also send out a prompt tone so as to remind a driver of mistakenly stepping on the accelerator. Meanwhile, the vehicle controller can also control the horn to blast, and the horn can be used for sending out voice information such as prompt sound or warning sound. It can be appreciated that the loudspeaker can be divided into an internal loudspeaker and an external loudspeaker, for example, the internal loudspeaker can send out the voice for warning the driver that the accelerator is stepped on by mistake, and the external loudspeaker can send out the voice for prompting the surrounding people that the driver is stepped on by mistake, so that the risk is further reduced.
In one embodiment, after determining the execution strategy adopted by the execution module according to the vehicle speed of the vehicle acquired by the vehicle speed sensor, the method further comprises the following steps:
acquiring the depth of an accelerator pedal;
and judging whether the mistaken stepping state of the accelerator is ended or not according to the obtained depth of the accelerator pedal.
Specifically, after the vehicle controller controls the execution module to execute the corresponding execution strategy, the vehicle controller further needs to judge whether the accelerator is stepped on by mistake.
In one embodiment, determining whether the accelerator pedal mistaken stepping state is finished according to the acquired accelerator pedal depth acquired by the accelerator pedal depth sensor includes:
if the depth of the accelerator pedal is larger than the depth threshold, returning to execute the vehicle speed acquired according to the vehicle speed sensor, and determining an execution strategy adopted by the execution module;
if the depth of the accelerator pedal is smaller than or equal to the depth threshold value, the accelerator mistaken stepping state is ended.
Specifically, the depth threshold may be determined according to practical situations, and exemplary, the depth threshold may be 10%.
When the depth of the accelerator pedal is greater than 10%, the accelerator pedal is still in a state of being stepped on by mistake, and the operation needs to be returned to the step S320 to continue. And when the depth of the accelerator pedal is less than or equal to 10%, the accelerator pedal is in a normal state, and the accelerator pedal can be withdrawn from the mistaken stepping treatment. And then the whole vehicle controller can acquire the current actual accelerator pedal depth, load the corresponding driving or braking torque in the execution module according to the acquired accelerator pedal depth, and recover normal running.
In one embodiment, after the accelerator pedal error state is finished, the method may further include:
and controlling the motor controller to set the torque of the motor as the torque corresponding to the current accelerator pedal depth according to the accelerator pedal depth.
As shown in fig. 5, a flowchart of a specific embodiment of a method for preventing a throttle from being stepped on by mistake is shown, which includes:
s510, acquiring vehicle running parameters. Specifically, the whole vehicle controller acquires a switching signal through a switching module; the vehicle controller collects the running speed of the vehicle through a vehicle speed sensor; the whole vehicle controller determines the accelerator pedal depth and the like of the vehicle through the accelerator pedal depth sensor, and it is understood that the accelerator pedal depth is calculated after the whole vehicle controller collects the travel signal of the accelerator pedal sent by the accelerator pedal depth sensor.
S520, the whole vehicle controller judges whether the level of the switch signal sent by the switch module is changed, and if the level of the switch signal is not changed, the step S580 is executed; if the level of the received switching signal is changed, S530 is performed.
