Description
Technical Field
The invention belongs to the technical field of vehicle control, and particularly relates to an electronic parking brake automatic release control method, a controller and a vehicle.
Background
For a manual transmission automobile, an Engine Management System (EMS) needs to calculate the current gear of the vehicle according to the vehicle speed and the Engine speed. Therefore, when the vehicle is stationary, even if the driver engages the forward gear, the engine management unit cannot determine the actual gear of the vehicle and uniformly transmits the gear signal "N", that is, the neutral gear. On the other hand, in order to reduce the overall cost of the vehicle, the existing manual transmission vehicle is not equipped with a neutral switch, when the actual gear of the vehicle is placed in neutral, the engine management unit cannot distinguish neutral from a forward gear, and still sends a gear signal "N". In summary, the engine management unit of the existing manual transmission automobile cannot distinguish between neutral and forward gears when the vehicle is stationary, and transmits the gear signal "N".
Currently, more and more manual automobiles are beginning to use an electronic Parking system (EPB). The electronic parking system has an important function of automatically releasing the electronic parking brake, when the releasing condition is met, a driver steps on an accelerator pedal, and when the output torque of a driving shaft is greater than a calibrated value, the electronic parking system sends a command to an executing mechanism to release parking, so that the vehicle can start and run.
However, when the electronic parking system determines whether to execute the electronic parking brake automatic release function, the electronic parking system needs to refer to the gear signal sent by the engine management unit, and if the electronic parking brake automatic release function is not executed when the gear signal "N" is received (if other automatic release conditions are met), the actual gear of the vehicle is the forward gear, but the electronic parking system does not execute the electronic parking brake automatic release function. Therefore, it is necessary to adjust the corresponding control strategy of the electronic parking system to execute the electronic parking brake automatic release function when receiving the shift position signal "N" (if other automatic release conditions are satisfied), however, in this case, when the actual shift position of the vehicle is neutral, the electronic parking system also executes the electronic parking brake automatic release function, and if the vehicle is just stopped on a slope at this time, the problem that the vehicle runs down the slope due to the automatic release of the electronic parking brake under the condition that the driver does not step on the clutch and mistakenly steps on the accelerator is very likely to occur.
Disclosure of Invention
The invention aims to solve the problem that an engine management unit of the existing manual-gear automobile cannot distinguish a neutral gear from a forward gear when the automobile is static, so that a driver does not step on a clutch and mistakenly steps on an accelerator when the automobile is placed in the neutral gear, and the electronic parking brake is mistakenly and automatically released.
In order to achieve the above object, the present invention provides an electronic parking brake automatic release control method, a controller and a vehicle.

detecting whether a clutch pedal stroke signal of a target automobile conforms to the general variation trend of the clutch pedal stroke signal;
if yes, detecting whether the engine torque of the target automobile reaches a preset automobile starting torque or not;
and if so, releasing the electronic parking brake of the target automobile.
Preferably, the defining of the general trend of the change of the clutch pedal travel signal for reflecting the manual transmission automobile gear engaging process specifically comprises the following steps:
decomposing the manual gear automobile gear engaging process to obtain a plurality of stages;
defining a clutch pedal travel signal stage trend corresponding to each stage step;
and fitting all defined clutch pedal stroke signal stage trends according to the execution sequence of the stage steps to obtain the general variation trend of the clutch pedal stroke signals.
Preferably, in the process of decomposing the manual transmission vehicle gear engaging process into a plurality of stage steps, the manual transmission vehicle gear engaging process is decomposed into the stage steps of depressing the clutch pedal, engaging the gear and releasing the clutch pedal, which are sequentially executed.
Preferably, the step of depressing the clutch pedal corresponds to a clutch pedal stroke signal phase trend that: the magnitude of the clutch pedal travel signal rises from a predetermined first reference magnitude and exceeds a predetermined second reference magnitude.
Preferably, the phase step of engaging the gear corresponds to a phase trend of the clutch pedal stroke signal:
the amplitude of the clutch pedal travel signal remains stable and greater than the second reference amplitude.
Preferably, the clutch pedal stroke signal phase trend corresponding to the phase step of releasing the clutch pedal is as follows: the magnitude of the clutch pedal travel signal is reduced to the second reference magnitude and continues to be reduced to the first reference magnitude.
Preferably, the detecting whether the clutch pedal stroke signal of the target vehicle conforms to the general variation trend of the clutch pedal stroke signal specifically includes:
detecting whether the amplitude change of the current stage of the clutch pedal stroke signal conforms to the stage trend of the clutch pedal stroke signal corresponding to the stage step of treading the clutch pedal;
if yes, detecting whether the amplitude change of the next stage of the clutch pedal stroke signal meets the stage trend of the clutch pedal stroke signal corresponding to the stage step of engaging the gear;
if yes, detecting whether the amplitude change of the next stage of the clutch pedal stroke signal meets the stage trend of the clutch pedal stroke signal corresponding to the stage step of releasing the clutch pedal;
and if so, judging that the clutch pedal stroke signal of the detection target automobile conforms to the general variation trend of the clutch pedal stroke signal.
Preferably, the detecting whether the clutch pedal stroke signal of the target vehicle conforms to the general variation trend of the clutch pedal stroke signal specifically includes:
detecting whether the current amplitude of the clutch pedal travel signal is greater than the second reference amplitude;
if so, detecting whether the subsequent amplitude of the clutch pedal travel signal is smaller than the second reference amplitude and larger than the first reference amplitude;
and if so, judging that the clutch pedal stroke signal of the detection target automobile conforms to the general variation trend of the clutch pedal stroke signal.
According to a second aspect of the present invention, there is provided a controller for implementing any one of the above-described electronic parking brake automatic release control methods, the controller comprising a processor and a memory, the processor implementing any one of the above-described electronic parking brake automatic release control methods when executing a computer program stored in the memory.
According to a third aspect of the present invention, there is provided a vehicle including the controller described above for implementing any one of the electronic parking brake automatic release control methods described above.
The invention has the beneficial effects that:
the method comprises the steps of firstly defining a clutch pedal stroke signal overall change trend used for reflecting the gear engaging process of a manual gear automobile, then detecting whether a clutch pedal stroke signal of a target automobile accords with the clutch pedal stroke signal overall change trend, when detecting that the clutch pedal stroke signal of the target automobile accords with the clutch pedal stroke signal overall change trend, continuously detecting whether the engine torque of the target automobile reaches a preset automobile starting torque, and when detecting that the engine torque of the target automobile reaches the preset automobile starting torque, releasing the electronic parking brake of the target automobile.
The method for controlling the automatic release of the electronic parking brake judges whether a target automobile is in a forward gear or not by detecting whether a clutch pedal stroke signal of the target automobile accords with the general variation trend of the clutch pedal stroke signal corresponding to the gear engaging process of a manual gear automobile, and releases the electronic parking brake of the target automobile when the engine torque of the target automobile is continuously detected to reach the preset automobile starting torque after the target automobile is judged to be in the forward gear. And when the actual gear of the vehicle is neutral, because the vehicle gear engaging process is not generated, the clutch pedal stroke signal of the target vehicle does not conform to the general variation trend of the clutch pedal stroke signal corresponding to the manual gear vehicle gear engaging process, and even if the engine torque of the target vehicle reaches the preset vehicle starting torque, the electronic parking brake of the target vehicle cannot be released. Therefore, the method for controlling the automatic release of the electronic parking brake can effectively solve the problem that the electronic parking brake is mistakenly and automatically released under the conditions that a driver does not step on a clutch and mistakenly steps on an accelerator when the vehicle is placed in a neutral position because an engine management unit of the conventional manual transmission automobile cannot distinguish the neutral position from a forward gear when the vehicle is static.
The controller and the vehicle of the present invention and the electronic parking brake automatic release control method belong to a general inventive concept, and thus have the same advantageous effects as the electronic parking brake automatic release control method.

Detailed Description
Preferred embodiments of the present invention will be described in more detail below. While the following describes preferred embodiments of the present invention, it should be understood that the present invention may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example (b): fig. 1 shows a flowchart for implementing an electronic parking brake automatic release control method according to an embodiment of the present invention.

s100, defining a general variation trend of a clutch pedal travel signal for reflecting the manual gear automobile gear engaging process;
step S200, detecting whether a clutch pedal stroke signal of a target automobile accords with the general variation trend of the clutch pedal stroke signal, if so, executing step S300;
step S300, detecting whether the engine torque of the target automobile reaches a preset automobile starting torque, if so, executing step S400;
and releasing the electronic parking brake of the target automobile.
Further, fig. 2 shows a flowchart of an implementation of the method for defining the general variation trend of the clutch pedal stroke signal according to the embodiment of the invention. Referring to fig. 2, in the embodiment of the present invention, the defining the general trend of the clutch pedal travel signal for reflecting the manual transmission vehicle gear engaging process in step S100 specifically includes:
step S110, decomposing the manual gear automobile gear engaging process to obtain a plurality of stages;
step S120, defining a clutch pedal stroke signal stage trend corresponding to each stage step;
and S130, fitting all defined clutch pedal stroke signal stage trends according to the execution sequence of the stage steps to obtain the total variation trend of the clutch pedal stroke signals.
Specifically, in the embodiment of the present invention, in the process of decomposing the manual transmission vehicle engaging process to obtain a plurality of stage steps in step S110, the manual transmission vehicle engaging process is decomposed into stage steps of sequentially executing the clutch pedal depression, the gear engagement, and the clutch pedal release.
Specifically, in the embodiment of the present invention, the clutch pedal stroke signal phase trend corresponding to the phase step of depressing the clutch pedal is as follows: the magnitude of the clutch pedal travel signal rises from a predetermined first reference magnitude and exceeds a predetermined second reference magnitude.
Specifically, in the embodiment of the present invention, the phase trend of the clutch pedal stroke signal corresponding to the phase step of engaging the gear is as follows: the amplitude of the clutch pedal travel signal remains stable and greater than the second reference amplitude.
Specifically, in the embodiment of the present invention, the clutch pedal stroke signal phase trend corresponding to the phase step of releasing the clutch pedal is as follows: the magnitude of the clutch pedal travel signal is reduced to the second reference magnitude and continues to be reduced to the first reference magnitude.
In the embodiment of the invention, the first reference amplitude is set to be 5% of the maximum amplitude of the clutch pedal stroke signal, the second reference amplitude is set to be 80% of the maximum amplitude of the clutch pedal stroke signal, and an effective clutch stroke interval is determined through the first reference amplitude and the second reference amplitude. In fact, for the manual transmission type, the travel signal of the clutch pedal sent by the engine management unit to the CAN bus is a range (0% -100%), 0% indicating that the clutch pedal is completely released, and 100% indicating that the clutch pedal is completely depressed. Therefore, in practical use, the first reference amplitude may be set to 5% and the second reference amplitude may be set to 80%.
Still further, fig. 3 shows a flowchart of an implementation of a method for detecting whether a clutch pedal stroke signal of a target vehicle conforms to a general variation trend of the clutch pedal stroke signal according to an embodiment of the present invention.

step S230, detecting whether the amplitude change of the next stage of the clutch pedal stroke signal conforms to the stage trend of the clutch pedal stroke signal corresponding to the stage step of releasing the clutch pedal, if so, executing step S240;
and S240, judging that the clutch pedal stroke signal of the detection target automobile conforms to the general variation trend of the clutch pedal stroke signal.
Optionally, fig. 4 shows a flowchart of another implementation of the method for detecting whether the clutch pedal stroke signal of the target vehicle conforms to the general variation trend of the clutch pedal stroke signal according to the embodiment of the invention. Referring to fig. 4, in the embodiment of the present invention, the detecting whether the clutch pedal stroke signal of the target vehicle in step S200 conforms to the general variation trend of the clutch pedal stroke signal specifically includes:
step S210', detecting whether the current amplitude of the travel signal of the clutch pedal is greater than the second reference amplitude, if so, executing step S220';
step S220', detecting whether a subsequent amplitude of the clutch pedal stroke signal is smaller than the second reference amplitude and larger than the first reference amplitude, if so, executing step S230';
and step S230', judging that the clutch pedal stroke signal of the detection target automobile conforms to the general variation trend of the clutch pedal stroke signal.
In the embodiment of the present invention, compared with the method for detecting whether the clutch pedal stroke signal of the target automobile shown in fig. 3 conforms to the general variation trend of the clutch pedal stroke signal, the method for detecting whether the clutch pedal stroke signal of the target automobile conforms to the general variation trend of the clutch pedal stroke signal shown in fig. 4 is simpler and more convenient, and the specific principle is as follows: the normal starting process of the gear engagement is that the clutch pedal is stepped on → the gear engagement → the clutch pedal is released and the accelerator pedal is simultaneously stepped on, when the travel signal of the clutch pedal is more than 80%, the process indicates that the driver steps on the clutch pedal and engages the gear, and when the travel signal of the clutch pedal is reduced to between 5% and 8%, the process indicates that the driver releases the clutch pedal and prepares for starting. When a driver steps on an accelerator pedal, and the engine torque of a target automobile reaches the preset automobile starting torque, the electronic parking brake is automatically released. It is known that the electronic parking brake is automatically released only when the change in the clutch pedal stroke signal is detected. If the clutch pedal stroke signal is not changed, the driver only simply steps on the accelerator pedal, and even if the engine torque meets the starting requirement, the electronic parking brake cannot be automatically released.
According to the automatic release control method for the electronic parking brake, the actual gear of the vehicle is judged based on the travel signal of the clutch pedal, so that the problem that the vehicle slips down on a slope due to the automatic release of the electronic parking brake when the manual transmission vehicle is placed in a neutral position and only the accelerator is stepped without stepping on the clutch can be effectively solved. In addition, the electronic parking brake automatic release control method provided by the embodiment of the invention also provides a concept of an effective clutch stroke interval for judging the semi-linkage state of the clutch.
Accordingly, an embodiment of the present invention further provides a controller for implementing any of the above-mentioned electronic parking brake automatic release control methods according to embodiments of the present invention, the controller including a processor and a memory, the processor implementing any of the above-mentioned electronic parking brake automatic release control methods according to embodiments of the present invention when executing the computer program stored in the memory.
Accordingly, an embodiment of the present invention further provides a vehicle including the above controller for implementing any one of the above electronic parking brake automatic release control methods according to the embodiments of the present invention.
Having described embodiments of the present invention, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
