Description
Technical Field
The invention relates to the field of electric automobiles, in particular to an abnormal catapult starting processing method, an abnormal catapult starting processing device, a storage medium and an electric automobile.
Background
The new energy automobile adopts unconventional automobile fuel as a power source (or adopts conventional automobile fuel and a novel vehicle-mounted power device), integrates advanced technologies in the aspects of power control and driving of the automobile, and forms an automobile with advanced technical principle, new technology and new structure. The electric automobile is a new energy automobile, and refers to a vehicle which uses a vehicle-mounted power supply as power and uses a motor to drive wheels to run, and meets various requirements of road traffic and safety regulations. Because the electric automobile has smaller influence on the environment compared with the traditional automobile, the prospect of the electric automobile is widely seen.
Generally, for the control of an electric vehicle, when an accelerator pedal and a brake pedal are simultaneously depressed during normal running of the vehicle, a vehicle controller does not output both signals to an actuator of the vehicle at the same time, but only responds to the actuation of a brake pedal signal for safety.
The catapult starting of the automobile is used as a quick starting mode of the automobile, can obtain larger acceleration when the automobile is started, realizes quick starting, and enables the automobile to have better acceleration performance when the automobile is started, so that more and more new energy automobiles have special catapult starting control strategies at present. For a driver, the concrete operation for realizing the launch starting is that when the vehicle is static, the driver deeply steps on a brake pedal to keep the vehicle static, then steps on an accelerator pedal to enable wheels to have certain initial torque, and finally quickly releases the brake pedal to start the launch starting.
In the traditional launch starting mode, the intention and misoperation of a driver who steps on a brake pedal first and then an accelerator pedal or steps on the accelerator pedal first and then the brake pedal cannot be distinguished. If the driver steps on the accelerator pedal to prepare for starting, an emergency or sudden situation occurs at the moment, the driver deeply steps on the brake pedal when the accelerator pedal is not released due to overstrain, the real intention of the driver is to stop and not start at the moment, a control strategy for judging the brake pedal and the accelerator pedal in sequence is not available, and the vehicle possibly enters a launch starting mode by mistake at the moment because the process is carried out quickly and the vehicle speed is zero.
In addition, even if the driver does not completely send the brake pedal to 0 although the brake pedal is quickly released, a small braking force still exists at the moment, the driving force is far greater than the braking force, and the automobile can be launched. As the speed of the vehicle is increased, the braking force exists, which causes abnormal abrasion of the brake pad and overheating of the brake disc, thus endangering the driving safety.

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 invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected" and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
In the prior art, the launch start of an automobile is taken as a quick start mode of the automobile, a large acceleration can be obtained when the automobile is started, the quick start is realized, and the automobile has better acceleration performance when being started, so that more and more new energy automobiles have special launch start control strategies. For a driver, the concrete operation for realizing the launch starting is that when the vehicle is static, the driver deeply steps on a brake pedal to keep the vehicle static, then steps on an accelerator pedal to enable wheels to have certain initial torque, and finally quickly releases the brake pedal to start the launch starting.
In the traditional launch starting mode, the intention and misoperation of a driver who steps on a brake pedal first and then an accelerator pedal or steps on the accelerator pedal first and then the brake pedal cannot be distinguished. If the driver steps on the accelerator pedal to prepare for starting, an emergency or sudden situation occurs at the moment, the driver deeply steps on the brake pedal when the accelerator pedal is not released due to overstrain, the real intention of the driver is to stop and not start at the moment, a control strategy for judging the brake pedal and the accelerator pedal in sequence is not available, and the vehicle possibly enters a launch starting mode by mistake at the moment because the process is carried out quickly and the vehicle speed is zero.
In addition, even if the driver does not completely send the brake pedal to 0 although the brake pedal is quickly released, a small braking force still exists at the moment, the driving force is far greater than the braking force, and the automobile can be subjected to catapult starting. As the vehicle speed becomes faster, the brake force exists again, which can cause the abnormal abrasion of the brake block and the overheating of the brake disc, thus endangering the driving safety.
This will be explained in detail in the following exemplary embodiments:
referring to fig. 1, fig. 1 shows an abnormal launch starting processing method provided in an exemplary embodiment of the present invention, which includes the following steps:
acquiring the power-on condition of the whole vehicle and the fault condition of the whole vehicle, and entering a default mode when the power-on is successful and no fault exists; the default mode is: when the brake pedal state and the accelerator pedal state are both in a non-release state, outputting a command for only executing brake control;
in a default mode, acquiring a brake pedal state and an accelerator pedal state, and when the brake pedal state is a non-release state and the accelerator pedal state is a release state, adjusting the default state into a launch starting preparation mode;
acquiring a brake pedal state and an accelerator pedal state in a launch starting preparation mode, and adjusting the launch starting preparation mode to a launch starting mode when the brake pedal state and the accelerator pedal state are both in a non-release state;
and under the launch starting mode, acquiring the state of a brake pedal, acquiring the real-time vehicle speed when the state of the brake pedal is a non-release state, and adjusting the launch starting mode to be a default mode when the real-time vehicle speed is greater than a first preset value.
Specifically, in the exemplary embodiment, after initialization (power-on and failure determination) is completed, it is determined whether a brake pedal state is satisfied and an accelerator pedal state is not satisfied, that is, it is determined that a driver steps on a brake first at this time, and then an launch start preparation mode is entered; and then, in the launch starting preparation mode, judging whether the driver steps on the accelerator pedal under the state that the brake pedal is not released, namely correspondingly judging that the state of the brake pedal and the state of the accelerator pedal are both in a non-released state, and if so, adjusting the launch starting preparation mode to the launch starting mode.
Then, in an ejection starting mode, starting to perform ejection starting, wherein in a normal case, a driver needs to quickly release a brake pedal, and the vehicle directly obtains output to complete the ejection starting, however, if in the ejection starting mode, the speed of releasing the brake pedal by the driver is too slow, so that the driving torque of the vehicle is greater than the braking torque, and the vehicle can perform the ejection starting, but as the vehicle speed becomes fast, and the braking force exists, if in the case of a certain vehicle speed and the braking force exists, abnormal wear of a brake pad and overheating of a brake disc can be caused, therefore, in this exemplary embodiment, in the ejection starting mode, a brake pedal state is obtained, when the brake pedal state is in a non-release state (i.e., the driver has not completely released the brake pedal), a real-time vehicle speed is obtained, and when the real-time vehicle speed is greater than a first preset value, the ejection starting mode is adjusted to be a default mode, at this time: if the brake pedal state and the accelerator pedal state are both in a non-release state, outputting an instruction for only executing brake control, and not receiving an acceleration instruction of the accelerator pedal; if the brake pedal is in a non-released state and the accelerator pedal is in a released state, only the command of the brake control is executed because only the brake pedal is used. When the vehicle jumps back to the default mode, the launch start is considered to be failed, and the driver needs to perform the launch start operation again to perform the launch start again.
Specifically, by adopting the mode, the original whole vehicle control model framework does not need to be changed or adjusted, and only a plurality of judgment conditions and control strategies need to be added to the existing launch starting module. When the vehicle is launched, started and stored with power, and when the driver has improper operation or error, and the brake pedal is slightly stepped (namely, the brake pedal with the opening degree of 10-20 can be loosened) and the wheel has torque, the vehicle returns to the default mode of only executing the brake operation when the vehicle reaches a certain speed. That is, the present exemplary embodiment can directly exit the catapulting mode at the initial stage of the situation, i.e., when a certain vehicle speed (the first preset value) is determined, thereby preventing the waste of energy, the excessive wear of the brake pad and the overheating of the brake disc, and improving the driving safety.
It should be noted that the first preset value is a settable value, and can be set comprehensively according to the vehicle type, the service life of the vehicle, the vehicle type, and other conditions. Also, the first preset value may be set to a smaller value so that exit may be achieved when the vehicle speed is smaller.
In addition, for the unclamped state and the non-unclamped state: the released state represents a state in which the pedal is completely released, i.e., the brake pedal or the accelerator pedal is not depressed by the driver; and the non-released state indicates a state in which the pedal portion is depressed or fully depressed, i.e., the brake pedal or the accelerator pedal is depressed or partially depressed by the driver.
More preferably, in an exemplary embodiment, the method further comprises the steps of:
and in the default mode, acquiring a brake pedal state and an accelerator pedal state, and keeping the default state when the brake pedal state is a released state or the brake pedal state and the accelerator pedal state are both non-released states.
Specifically, in this exemplary embodiment, the steps in the foregoing exemplary embodiment may be combined to determine the sequence of stepping on the brake pedal and the accelerator pedal, so as to more clearly determine the real intention of the driver and prevent or reduce the potential safety hazard caused by misoperation. Namely: the real intention of the driver is fully judged by two conditions before the start of the conventional launch: (1) In a default state, firstly, judging whether a brake pedal state and an accelerator pedal-free state are met or not, so as to judge that a driver steps on a brake first and then enters an ejection starting preparation state; (2) Meanwhile, in the launch starting preparation state, if the brake pedal state is not available at the moment, the driver is judged to give up launch starting or have no launch starting intention, and then the driver is returned to the default state.
Preferably, in an exemplary embodiment, in the launch preparation mode, the brake pedal state and the accelerator pedal state are obtained, and when the brake pedal state and the accelerator pedal state are both in a non-release state, the launch preparation mode is adjusted to the launch mode, and is replaced by:
in the launch starting preparation mode, a brake pedal state and an accelerator pedal state are obtained, and when the brake pedal state and the accelerator pedal state are both in a non-release state, a braking torque generated by the brake pedal and a driving torque generated by the accelerator pedal are obtained; when the braking torque is larger than the driving torque, the launch starting preparation mode is adjusted to be a launch starting mode; and when the braking torque is smaller than the driving torque, adjusting the catapult starting preparation mode to be the default mode.
Specifically, in the exemplary embodiment, the preferable deployment is made for the case of the launch start preparation mode, and the main corresponding problems are: in the existing catapult starting control, a brake signal is only a state quantity, and the brake signal is 1 when a brake force exists (no matter the magnitude of the brake force exists), and is 0 when no brake force exists; when a driver simultaneously steps on a brake pedal and an accelerator pedal to prepare for entering an ejection starting mode, the brake force stepped on by the driver is small, but a brake signal exists, at the moment, the driving force is also output, and if the driving force is larger than the brake force, the automobile overcomes the problem that the brake force advances, so that energy waste and abnormal abrasion of a brake pad are caused.
In the exemplary embodiment, in the launch starting preparation mode, when the brake pedal state and the accelerator pedal state are both in a non-release state, the situation is that the launch starting mode is prepared to be entered, and at this time, the braking torque generated by the brake pedal and the driving torque generated by the accelerator pedal are obtained; when the braking torque is larger than the driving torque, the launch starting preparation mode is adjusted to be a launch starting mode; and when the braking torque is smaller than the driving torque, the catapult starting preparation mode is adjusted to be the default mode. Therefore, the problems that when the braking force stepped by a driver is small but a braking signal exists, if the driving force is larger than the braking force, the automobile overcomes the problems that the braking force advances, energy is wasted and the brake pad is abnormally abraded are solved, the catapult starting preparation mode is adjusted to be the default mode, and at the moment, because the brake pedal is in a non-release state, an instruction of only executing brake control is output, and the automobile cannot advance forwards.
It should be noted that, for the calculation of the braking torque and the driving torque, the following method may be referred to, or any one of the methods in the prior art may be referred to: the driving torque is obtained by the torque T of the driving motor and the speed ratio i; the braking torque is obtained by pushing the brake calipers to clamp the brake disc through the oil way after the brake pedal is stepped on to generate total braking torque, and when the pedal opening degree of the brake pedal is larger, the braking torque is larger.
More preferably, in an exemplary embodiment, the method further comprises the steps of:
and under the launch starting mode, acquiring the time when the brake pedal state and the accelerator pedal state are both in a non-release state, and adjusting the launch starting mode to be a default mode when the time exceeds a second preset value.
Specifically, in the exemplary embodiment, when the brake pedal and the accelerator pedal are simultaneously depressed for too long time in the launch start mode, the launch start mode is exited to enter the default mode, the launch start fails, and overheating caused by keeping torque output of the motor at a standstill can be prevented. Under the normal condition, in the launch starting mode, the driver quickly releases the brake pedal (before the time exceeds a second preset value), and returns to the default mode, and the torque on the wheels of the automobile is directly output at the moment to finish launch starting.
It should be noted that the second preset value is a settable value, and can be selected comprehensively according to various situations such as vehicle type and motor type.
The present invention has the same inventive concept as the above-described exemplary embodiment, and yet another exemplary embodiment of the present invention provides an abnormal projectile starting processing device including:
an initialization module: the system is used for acquiring the power-on condition of the whole vehicle and the fault condition of the whole vehicle, and when the power-on is successful and no fault exists, the system enters a default mode; the default mode is: when the brake pedal state and the accelerator pedal state are both in a non-release state, outputting a command for only executing brake control;
the catapult starting preparation judging module: the system comprises a control module, a starting module and a starting module, wherein the control module is used for acquiring a brake pedal state and an accelerator pedal state in a default mode, and adjusting the default state to a launch starting preparation mode when the brake pedal state is a non-release state and the accelerator pedal state is a release state;
the launch starting judging module: the system comprises a control module, a control module and a control module, wherein the control module is used for acquiring a brake pedal state and an accelerator pedal state in a launch starting preparation mode, and adjusting the launch starting preparation mode to a launch starting mode when the brake pedal state and the accelerator pedal state are both in a non-release state;
an abnormal catapult starting judgment module: the method comprises the steps of obtaining the state of a brake pedal in an ejection starting mode, obtaining the real-time vehicle speed when the state of the brake pedal is a non-loosening state, and adjusting the ejection starting mode to be a default mode when the real-time vehicle speed is larger than a first preset value.
Like the method in the exemplary embodiment, the method is adopted, the original whole vehicle control model framework does not need to be changed or adjusted, and only a plurality of judgment conditions and control strategies need to be added in the existing launch starting module. When the vehicle is launched, started and stored with power, and when the driver has improper operation or error, and the brake pedal is slightly stepped (namely, the brake pedal with the opening degree of 10-20 can be loosened) and the wheel has torque, the vehicle returns to the default mode of only executing the brake operation when the vehicle reaches a certain speed. That is, the present exemplary embodiment can directly exit the catapulting mode at the initial stage of the situation, i.e., when a certain vehicle speed (the first preset value) is determined, thereby preventing the waste of energy, the excessive wear of the brake pad and the overheating of the brake disc, and improving the driving safety.
Preferably, in an exemplary embodiment, the launch preparation determining module is further configured to:
and in the default mode, acquiring a brake pedal state and an accelerator pedal state, and keeping the default state when the brake pedal state is a released state or the brake pedal state and the accelerator pedal state are both non-released states.
The same as the method in the exemplary embodiment, the steps in the exemplary embodiment can be matched to judge the sequence of stepping on the brake pedal and the accelerator pedal, so that the real intention of the driver can be judged more clearly, and the potential safety hazard caused by misoperation can be prevented or reduced. Namely: the real intention of the driver is fully judged by two conditions before the start of the conventional launch: (1) In a default state, firstly, judging whether a brake pedal state and an accelerator pedal-free state are met or not, so as to judge that a driver steps on a brake first and then enters an ejection starting preparation state; (2) Meanwhile, in the launch starting preparation state, if the brake pedal state is not available at the moment, the driver is judged to give up launch starting or have no launch starting intention, and then the driver is returned to the default state.
Preferably, in an exemplary embodiment, the launch start determining module is replaced with:
the system comprises a control module, a control module and a control module, wherein the control module is used for acquiring a brake pedal state and an accelerator pedal state in a launch starting preparation mode, and acquiring a braking torque generated by the brake pedal and a driving torque generated by the accelerator pedal when the brake pedal state and the accelerator pedal state are both in a non-release state; when the braking torque is larger than the driving torque, the launch starting preparation mode is adjusted to be a launch starting mode; and when the braking torque is smaller than the driving torque, adjusting the catapult starting preparation mode to be the default mode.
In the same way as in the foregoing method exemplary embodiment, in the launch starting preparation mode, when the brake pedal state and the accelerator pedal state are both in the non-release state, which is the case of the standard preparation for entering the launch starting mode, the braking torque generated by the brake pedal and the driving torque generated by the accelerator pedal are acquired at this time; when the braking torque is larger than the driving torque, the launch starting preparation mode is adjusted to be a launch starting mode; and when the braking torque is smaller than the driving torque, the catapult starting preparation mode is adjusted to be the default mode. Therefore, the problems that when the braking force stepped by a driver is small but a braking signal exists, if the driving force is larger than the braking force, the automobile overcomes the problems that the braking force advances, energy is wasted and the brake pad is abnormally abraded are solved, the catapult starting preparation mode is adjusted to be the default mode, and at the moment, because the brake pedal is in a non-release state, an instruction of only executing brake control is output, and the automobile cannot advance forwards.
Preferably, in an exemplary embodiment, the abnormal launch starting determining module is further configured to:
and under the launch starting mode, acquiring the time when the brake pedal state and the accelerator pedal state are both in a non-release state, and adjusting the launch starting mode to be a default mode when the time exceeds a second preset value.
Like the method exemplary embodiment, when the brake pedal and the accelerator pedal are simultaneously pressed for too long time in the launch starting mode, the launch starting mode is exited to enter the default mode, the launch starting fails, and overheating caused by keeping torque output of the motor at a standstill can be prevented. Under the normal condition, in the launch starting mode, the driver quickly releases the brake pedal (before the time exceeds a second preset value), and returns to the default mode, and the torque on the wheels of the automobile is directly output at the moment to finish launch starting.
Having the same inventive concept as the above-described exemplary embodiment, a further exemplary embodiment of the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when being executed by a processor, performs the steps of the method for processing abnormal catapult-assisted launch based on an electric vehicle.
Based on such understanding, the technical solution of the present embodiment or parts of the technical solution may be essentially implemented in the form of a software product (program product) stored in a storage medium, and including instructions for causing a computer device (which may be a personal computer, a server, or a network device) to execute all or part of the steps of the method according to the embodiments of the present invention.
