Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
A possible application scenario of the present disclosure is first explained.
When the driver intends to move the vehicle for a short distance after the EPB performs the braking operation, if the vehicle is started without fastening the seatbelt, the EPB is not automatically released, and the vehicle is still stationary even if the engine speed is increased by depressing the accelerator pedal. The driver who is unfamiliar with the vehicle can think that the vehicle has a fault, also wasted energy simultaneously, made the exhaust emission increase, is unfavorable for the environmental protection.
In view of the above, the present disclosure provides a method and an apparatus for controlling an electronic parking system, and a vehicle, so as to solve the above problems.
Fig. 1 is a flowchart of a control method of an electronic parking system according to an exemplary embodiment. Referring to fig. 1, a first aspect of the present disclosure provides a control method of an electronic parking system, including:
step S11, after the electronic parking system executes the braking action, if a vehicle driving command is received, determining whether the safety belt of the driving position is in a locking state at present;
after the electronic parking system executes a braking action, the vehicle is in a static state, and when a vehicle driving command is received, namely the power system of the vehicle starts to output power, whether the safety belt of a driving position is in a locked state currently is determined.
For example, a sensor may be provided in the buckle of the seat belt, and a signal of the sensor may determine whether the seat belt of the driver seat is currently in the locked state.
Illustratively, the sensor may be a photoelectric gate, a travel switch, or the like.
Step S12, if the safety belt is not in the locking state, determining whether the current state parameter of the vehicle meets the preset safe driving condition;
if the safety belt is not in the locked state, at this time, the driver does not have enough safety guarantee to drive the vehicle, and it is necessary to determine whether the current state parameters of the vehicle meet the preset safe driving conditions, so as to determine the safety performance of the vehicle.
And step S13, in the case that the current state parameters of the vehicle are determined to meet the preset safe driving conditions, controlling the electronic parking system to release.
When the current state parameters of the vehicle are determined to meet the preset safe driving conditions, namely the safety performance of the vehicle meets the requirement that the driver does not wear a safety belt to drive, the electronic parking system is controlled to release at the moment so as to meet the requirement that the driver moves the vehicle momentarily, and the driver can move the vehicle in a short distance.
Illustratively, the state parameters may include: seat state information, functional safety level and thrust torque of a driver seat; accordingly, the safe driving conditions include: the seat state information represents that a driver sits on a driving seat, the functional safety level reaches a preset safety level, and the thrust torque is not less than the brake torque.
By determining that the driver sits on the driving position, the vehicle can be ensured to be operated by the driver at present, and the vehicle is prevented from being started due to falling of articles or touching of animals and the like, so that the safety is improved.
By determining that the functional safety level reaches the preset safety level, the possibility of systematic failure can be reduced, and the driving safety of a driver is improved.
Illustratively, the functional security Level is classified according to ASIL (english: automatic security integrity Level, chinese: Automotive security integrity Level).
Illustratively, the preset security level is ASIL-B.
By determining that the thrust torque is not less than the brake torque, smooth forward movement of the vehicle can be ensured after the electronic parking system is released.
Illustratively, the braking torque is, in particular, the braking torque actually required by the vehicle.
Illustratively, the vehicle drive command may include an accelerator pedal signal.
For example, the vehicle drive command may include a clutch engagement signal
For example, the vehicle drive commands may include an accelerator pedal signal and a clutch engagement signal. Therefore, the electronic parking system can be released only after the accelerator pedal signal and the clutch engaging signal are received, and accidental release of the electronic parking system caused by misoperation of a user is avoided.
For example, the seat state information of the driver seat may be acquired by a seat sensor.
For example, the seat sensor may be a piezo-resistor, and when the driver is seated on the driving seat, the resistance value of the piezo-resistor changes to enable determination as to whether the driver is seated on the driving seat.
For example, the accelerator pedal signal may be obtained by a travel switch on the accelerator pedal, and when the driver steps on the accelerator pedal, the travel switch on the accelerator pedal is activated to obtain the accelerator pedal signal.
Fig. 2 is a flowchart of a control method of an electronic parking system according to still another exemplary embodiment. Referring to fig. 2, after controlling the electronic parking system to be released, the control method may further include:
step S14: judging whether the speed of the vehicle is greater than or equal to the boundary speed or not, and generating a first judgment result;
for example, the real-time speed of the vehicle may be obtained through a speed measuring device of the vehicle.
If the first determination result is yes, step S15 is executed: judging whether the current state parameters of the vehicle meet the release maintaining conditions or not, and generating a second judgment result;
when the second determination result is no, the current state parameter of the vehicle does not satisfy the maintenance release condition, that is, in the case where the vehicle speed is greater than or equal to the boundary speed, the current state parameter of the vehicle is not safe enough for the driver, so step S16 is executed at this time: the control prompting device prompts alarm information.
The control prompting device prompts the alarm information, so that a driver can timely know the current state of the vehicle and can timely take measures to improve the driving safety.
It is further noted that, by the above mode, the driver can drive at a low speed below the boundary speed without fastening the safety belt, and the use requirement of short-time vehicle moving of the driver can be met.
Illustratively, the status parameters may include seat status information of the driver's seat, functional safety level, thrust torque, seat belt failure information, seat belt status information; accordingly, maintaining the release conditions includes: the seat state information represents that a driver sits on a driving seat, the functional safety level reaches a preset safety level, the thrust torque is not less than the braking torque, the safety belt fault information represents that the safety belt is not in fault, and the safety belt state information represents that the safety belt is in a locking state.
By determining that the driver sits on the driving seat, the vehicle can be ensured to be operated by the driver at present, and the vehicle is prevented from being started due to falling of articles or touching of animals, so that the safety is improved.
By determining that the functional safety level reaches the preset safety level, the possibility of systematic failure can be reduced, and the driving safety of a driver is improved.
Illustratively, the preset security level is ASIL-B.
By determining that the thrust torque is not less than the braking torque, smooth forward movement of the vehicle can be ensured.
By determining that the safety belt is not in fault, the safety belt can work normally, and sufficient protection is provided for a driver.
By determining that the seat belt is in a locked state, it is ensured that the driver has fastened the seat belt, which can improve the safety of the driver when the vehicle speed is further increased.
Illustratively, the vehicle may be provided with an instrument panel, and the control prompting device prompts alarm information, and may include:
and controlling the instrument panel to display alarm information.
For example, when the seat belt state information indicates that the seat belt is not in the locked state, the instrument panel may be controlled to display an alarm message (e.g., "please fasten the seat belt"), and remind the user to fasten the seat belt.
For another example, when the safety belt fault information indicates that the safety belt has a fault, the instrument panel may be controlled to display alarm information (e.g., "safety belt fault"), so as to remind the user of the safety belt fault, and at the same time, a nearby maintenance point may be displayed, so that the user may move to the maintenance point quickly for maintenance.
Illustratively, the control prompting device prompts alarm information, and may further include:
the light of the control instrument board flickers so as to attract the attention of the driver and prevent the driver from not taking response measures in time due to the fact that the driver does not notice the alarm information.
For example, the brightness of the dashboard may be increased by displaying a specific color of the warning message or when the warning message is displayed, so as to attract the attention of the user.
Exemplarily, a speaker can be further arranged in the vehicle, and the control prompting device prompts alarm information, which can include:
and controlling the loudspeaker to play the alarm information.
Referring to fig. 2, the method of fig. 1 may further include step S17:
and if the second judgment result is yes, the current state parameters of the vehicle meet the release maintaining condition, the release state of the electronic parking system is maintained, and the vehicle can normally accelerate.
For example, the maintenance release condition may include seat state information indicating that the driver is seated in the driving seat, a functional safety level reaching a preset safety level, a thrust torque not less than a braking torque, a seatbelt failure information indicating that the seatbelt is not failed, and a seatbelt state information indicating that the seatbelt is in a locked state.
Thus, in the case where the driver is seated in the driving seat, the functional safety level reaches the preset level, and the thrust torque is not less than the braking torque, as long as the seatbelt is out of order and the seatbelt lock is in the locked state, even if the speed of the vehicle exceeds the boundary speed, the normal running can be accelerated.
Illustratively, the boundary speed is 7Km/h, and the boundary speed is 7Km/h, so that the requirement of a driver for low-speed driving can be met, operations such as vehicle moving and the like can be smoothly finished, the intensity of potential accidental collision can be controlled, and the life safety of the driver can be guaranteed.
Illustratively, the boundary velocity is 6.3 Km/h.
Illustratively, the boundary velocity is 7.7 Km/h.
It should be noted that the above preferred embodiments are only used for illustrating the principle of the present disclosure, and are not intended to limit the scope of the present disclosure. Without departing from the principles of the present disclosure, one skilled in the art can adjust the above-described arrangement so that the present disclosure can be applied to more specific application scenarios.
For example, although the foregoing embodiments illustrate several exemplary values of the boundary speed, those skilled in the art may set other values as the boundary speed without departing from the principles of the present disclosure, and for example, may take an appropriate value between 6.3Km/h and 7.7Km/h to meet the requirements of different scenarios.
Fig. 3 is a flowchart of a control method of an electronic parking system according to another exemplary embodiment. Referring to fig. 3, in the case where it is determined that the current state parameter of the vehicle does not satisfy the maintenance release condition, the control method may further include:
step S18: determining the duration of time that the current state parameters of the vehicle do not meet the release conditions;
step S19: and judging whether the duration reaches a first duration threshold value or not, generating a third judgment result, and if so, executing step S20 to control the steering wheel of the vehicle to vibrate so as to give a stronger prompt to the driver when the driver ignores the alarm information or does not notice the alarm information, so that the driver can take measures in time and the unsafe driving distance is reduced.
Step S21: judging whether the duration reaches a second duration threshold value or not, and generating a fourth judgment result;
wherein the second duration threshold is greater than the first duration threshold. If the third judgment result is yes, the current state parameters of the vehicle still do not meet the release maintaining condition after the steering wheel shakes, and the state parameters last for a period of time since the steering wheel starts shaking, so that the user still does not take measures to improve safety or decelerate at the moment, in order to prevent accidents, step S22 is executed, the output torque of the vehicle power system is controlled not to be larger than a preset value, the vehicle speed is limited by limiting the output torque, accidents caused by the fact that the vehicle speed is too fast and safety measures are not in place are avoided, and the safety of a driver is guaranteed.
For example, the vehicle speed may be controlled not to exceed 20Km/h by limiting the output torque to ensure driver safety.
Fig. 4 is a flowchart of a control method of an electronic parking system according to still another exemplary embodiment. Referring to fig. 4, in the case where it is determined that the current state parameter of the vehicle does not satisfy the maintenance release condition, the control method may further include:
step S23, judging whether a vehicle acceleration instruction is received or not, and generating a fifth judgment result;
when the fifth judgment result is yes, step S24 is executed to control the output torque of the vehicle powertrain system not to be greater than the preset value.
Through the mode, under the condition that the speed of the vehicle is greater than the boundary speed, if the vehicle acceleration instruction is received, the driver has the intention of further accelerating under the condition that the safety measure is not in place, at the moment, the speed of the vehicle is limited by limiting the output torque, accidents caused by the fact that the speed of the vehicle is too high and the safety measure is not in place are avoided, and the safety of the driver is guaranteed.
Illustratively, the vehicle acceleration command may be an accelerator pedal signal.
Alternatively, an acceleration sensor may be provided on the vehicle, and when the acceleration sensor feeds back an acceleration signal, the reception of the vehicle acceleration command is confirmed.
