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.
As described in the background art, in the conventional brake system, a vehicle is braked by a brake pedal, the brake pedal needs to be connected with a master cylinder through a mechanical structure in order to meet the requirement of brake backup, the position design of the brake pedal is relatively fixed, the identification and calculation of the braking requirement are limited to a specified component, and the design of the brake pedal is very limited. In addition, in the subsequent driverless scene, the brake pedal may even be cancelled, which may result in the brake and brake backup function not being realized. In addition, the braking mode commonly used at present is brake-by-wire, compared with the traditional braking system that a brake pedal and a brake booster are required to be mechanically connected, the brake-by-wire does not need to be mechanically connected, and the braking requirement of a driver is transmitted through a braking signal. However, in the brake-by-wire mode, once the brake signal collector or the brake booster fails, braking cannot be realized, that is, the current brake-by-wire mode has no brake backup function, so that potential safety hazards exist, and safety problems are easy to occur.
In order to solve the above problems, the present disclosure provides a vehicle braking method, system, storage medium, electronic device and vehicle, so as to flexibly implement vehicle braking and braking backup functions.
Fig. 1 is a schematic structural diagram of a vehicle brake system provided according to an embodiment of the present disclosure. As shown in fig. 1, the vehicle brake system 10 may include: a brake signal collector 11, a brake controller 12, a brake actuator 13 and a brake backup mechanism 14.
The brake signal collector 11 is used for collecting brake signals in the running process of the vehicle; the brake controller 12 is configured to obtain a brake signal and generate a brake control command according to the brake signal; the brake actuator 13 is used for receiving and responding to a brake control command to brake the vehicle; the brake backup mechanism 14 is used to provide the same function as the failed component in the event that any one or more of the brake signal collector 11, the brake controller 12, and the brake actuator 13 fails.
The driver can operate the brake signal collector 11 to transmit his own brake intention, the brake signal collector 11 can convert the driver's operation into a corresponding brake signal, and the brake signal collector can be independent of the brake actuator 13, that is, there may be no actual mechanical connection between the brake signal collector 11 and the brake actuator 13. The brake signal collector 11 may be provided as a separate brake simulation mechanism, which the driver can operate to transmit his own brake intention. The corresponding relation between the operation of the brake simulation mechanism and the brake signal can be calibrated in advance, so that after the driver operates the brake simulation mechanism, the corresponding brake signal is determined according to the actual operation of the driver and the pre-calibrated corresponding relation. For example, the brake simulation mechanism may be a brake pedal. Alternatively, the brake simulation mechanism may be provided at any position in the vehicle that can be operated by the driver. For example, the brake simulation mechanism may be provided at a center console of the vehicle. As another example, the brake simulation mechanism may be a pull-type emergency switch.
In one possible embodiment, the brake backup mechanism 14 may include a backup brake signal collector 21, the backup brake signal collector 21 being configured to collect a brake signal in case of failure of the brake signal collector 11.
Wherein, the backup brake signal collector 21 can set a designated number, for example, 1 or more according to the actual requirement. Preferably, in consideration of the setting cost, the number of the backup brake signal collectors 21 is 1 in the normal case. The backup brake signal collector 21 is selected and set in the same manner as the brake signal collector 11, which is not described herein again. Illustratively, the backup brake signal collector 21 may be provided at the center console. Alternatively, the backup brake signal collector 21 may select a device capable of recognizing a brake action, for example, an image capture device (e.g., a camera) capable of recognizing a specific gesture, and generate a brake signal when a specific brake action is captured.
The brake signal collector 11 can detect whether the function of collecting the brake signal of the brake signal collector 11 is normal in real time, if the function of collecting the brake signal is normal, it indicates that the signal collection of the brake signal collector 11 is not invalid, and if the function of collecting the brake signal is abnormal, it indicates that the signal collection of the brake signal collector 11 is invalid.
Under the condition that the signal acquisition of the brake signal collector 11 is not failed, the brake signal collector 11 completes the acquisition of the brake signal. In the event of failure of signal acquisition by the brake signal acquirer 11, the brake signal acquirer 11 generates first failure information for indicating failure of the brake signal acquirer 11. The brake signal collector 11 will then send this first failure information to the backup brake signal collector 21 and the brake controller 12.
The backup brake signal collector 21 is configured to collect a brake signal when the first failure information is received. The brake controller 12 is configured to obtain the brake signal from the backup brake signal collector 21 in case of receiving the first failure information.
That is to say, the brake signal collector 11 learns whether the function of collecting the brake signal of itself is failed through self-detection, and if the function is failed, the first failure information is sent to the backup brake signal collector 21 and the brake controller 12, so that the backup brake signal collector 21 replaces the brake signal collector 11 to complete the collection of the brake signal, and informs the brake controller 12 to directly obtain the brake signal from the backup brake signal collector 21.
Alternatively, the brake signal collector 11 can communicate with the brake controller 12 through the first communication channel or the second communication channel. That is, both the first communication channel and the second communication channel can satisfy the communication demand between both the brake signal collector 11 and the brake controller 12.
In one possible embodiment, the brake controller 12 also detects whether the first communication channel is failing, and the brake controller 12 obtains the brake signal through the first communication channel if it detects that the first communication channel is not failing, and obtains the brake signal through the second communication channel if it detects that the first communication channel is failing.
That is, for the communication between the brake signal collector 11 and the brake controller 12, in addition to providing the first communication channel, a backup second communication channel is also provided, so that, in case of failure of the first communication channel, the transmission of signals can be completed through the second communication channel, and the implementation of braking is ensured.
It should be noted that, in the case that the brake signal acquisition of the brake signal acquirer 11 fails, the backup brake signal acquirer 21 will replace the brake signal acquirer 11 to complete the acquisition of the brake signal, and therefore, the above description about the communication channel of the brake signal acquirer 11 can be equally applied to the backup brake signal acquirer 21.
The brake controller 12 is configured to obtain a brake signal and generate a brake control command according to the brake signal. The brake controller 12 may be provided with a brake demand identification module, which stores a corresponding relationship between the brake signal and the brake demand, and the corresponding relationship may be preset according to an actual demand, for example, different corresponding relationships may be set according to a vehicle type. Therefore, the braking intention of the driver can be recognized according to the acquired braking signal and the stored corresponding relation between the braking signal and the braking demand. Further, according to the braking intention, a braking control command conforming to the braking intention can be generated. Illustratively, the brake controller 12 may be an ECU (Electronic Control Unit).
In one possible embodiment, the brake backup mechanism 14 may include a backup brake controller 22, the backup brake controller 22 being configured to obtain a brake signal in the event of a failure of the brake controller 12 and to generate a brake control command based on the brake signal.
Wherein the backup brake controller 22 may set a specified number, for example, 1 or more, according to actual needs. Preferably, in consideration of the setting cost, the number of settings of the backup brake controller 22 is 1 in general. The backup brake controller 22 is selected and set in the same manner as the brake controller 12, and will not be described herein.
The backup brake controller 22 is able to detect if the brake controller 12 has failed. In the event that the brake controller 12 does not fail, a brake signal is obtained by the brake controller 12 and a brake control command is generated. If the backup brake controller 22 detects that the brake controller 12 is out of order, the backup brake controller 22 obtains a brake signal and generates a brake control command according to the brake signal.
That is, the backup brake controller 22 detects in real time whether the brake controller 12 has failed, and completes generation of brake control commands to complete subsequent vehicle braking in place of the brake controller 12 in the event that it is determined that the brake controller 12 has failed.
Alternatively, the backup brake controller 22 may also generate second failure information indicative of a failure of the brake controller 12 in the event that a failure of the brake controller 12 is detected. The backup brake controller 22 then sends the second failure information to the brake actuation structure 13. And the brake actuator 13 acquires a brake control command from the backup brake controller 22 in the case where the second failure information is received.
That is, if the brake controller 12 fails, the brake actuator 13 will know this via the second failure information, and thus the brake actuator 13 will not continue to obtain brake control commands from the brake controller 12, but will obtain brake control commands from the backup brake controller 22.
Alternatively, the brake controller 12 can communicate with the brake actuator 13 through a third communication channel or a fourth communication channel. That is, the third communication channel and the fourth communication channel can both satisfy the communication requirement between the brake controller 12 and the brake actuator 13.
In a possible embodiment, the brake actuator 13 also detects whether the third communication channel is disabled, and the brake actuator 13 obtains the brake control command through the third communication channel in case it detects that the third communication channel is not disabled, and obtains the brake control command through the fourth communication channel in case it detects that the third communication channel is disabled.
That is, for the communication between the brake controller 12 and the brake actuator 13, a backup fourth communication channel is provided in addition to the third communication channel, so that in case of failure of the third communication channel, the transmission of signals can be completed through the fourth communication channel, ensuring the implementation of the brake. ,
it should be noted that in the event of a failure of the brake controller 12, the backup brake controller 22 will complete the generation of brake control commands in place of the brake controller 12, and therefore the above description of the communication channel of the brake controller 12 is equally applicable to the backup brake controller 22.
The brake actuator 13 is responsive to the received brake control command to brake the vehicle. For example, the brake actuator may be a hydraulic brake mechanism. For another example, the brake actuator 13 may be a driving motor of a vehicle. If the brake actuator 13 is a driving motor of a vehicle, the brake control command may be a kinetic energy recovery command for the driving motor, so as to achieve the effect of braking the vehicle by requesting the driving motor to recover kinetic energy. The selection of the brake actuating mechanism 13 can be flexibly set according to actual conditions, and the aim of braking the vehicle can be achieved.
In one possible embodiment, the brake backup mechanism 14 may include a backup brake actuator 23, the backup brake actuator 23 being configured to respond to brake control commands in the event of a failure of the brake actuator 13.
The number of the backup brake actuators 23 may be set to a predetermined number, for example, 1 or more, according to actual requirements. Preferably, in consideration of the setting cost, the number of the backup brake actuators 23 is 1 in the normal case. The backup brake actuator 23 is selected and set in the same manner as the brake actuator 13, and will not be described herein.
The brake executing mechanism 13 may detect whether its own brake function is normal in real time, and if the brake function is normal, it indicates that the brake executing capability of the brake executing mechanism 13 is not failed, and if the brake function is not normal, it indicates that the brake executing capability of the brake executing mechanism 13 is failed.
In the case where the brake actuator 13 detects that its own brake actuation capability has not failed, the brake actuator 13 itself responds to the brake control command. When the brake actuator 13 detects that its own brake actuation capability is failed, the brake actuator 13 generates third failure information indicating that the brake actuator 13 has failed its own brake actuation capability. After that, the brake actuator 13 sends the third failure information to the backup brake actuator 23.
The backup brake actuator 23 receives and responds to the brake control command in the case of receiving the third failure information.
That is, if the brake executing capability of the brake executing mechanism 13 fails, the backup brake executing mechanism 23 will respond to the brake control command instead of the brake executing mechanism 13 to realize the braking of the vehicle.
Fig. 2 is a schematic diagram of an exemplary vehicle brake system, wherein the brake backup mechanism includes 1 backup brake signal collector, 1 backup brake controller, and 1 backup brake actuator.
The brake backup of the present disclosure is explained in connection with vehicle ESP (Electronic Stability Program) and IB (ibooster, Electronic booster). ESP can regulate the braking force of the driver, and IB can reduce the force of the driver to trigger the braking.
When the ESP and the IB are completely available, the ESP can acquire a brake signal, and after the brake signal is received, the ESP sends the brake signal to the IB to assist a driver to brake;
when IB fails and ESP is available, which is equivalent to the vacuum boosting failure of the traditional braking system, the braking backup is realized by means of the active braking capability of the ESP, which is equivalent to the braking without electronic boosting;
when the ESP fails and IB is available, IB can also obtain a brake signal from a third party ECU (Electronic Control Unit) to complete the braking.
According to the technical scheme, the vehicle braking system comprises a braking signal collector, a braking controller, a braking executing mechanism and a braking backup mechanism, wherein the braking signal collector is used for collecting braking signals in the running process of a vehicle, the braking controller is used for obtaining the braking signals and generating braking control instructions according to the braking signals, the braking executing mechanism is used for receiving and responding to the braking control instructions to brake the vehicle, and the braking backup mechanism is used for providing the same functions as a failure component under the condition that any one or more of the braking signal collector, the braking controller and the braking executing mechanism fails. Therefore, the independent brake signal collector is arranged, the brake signal collector is used for collecting the brake signals, the mechanical connection between the brake pedal and the brake transmission mechanism can be disconnected, and the flexibility of collecting the brake signals is improved. Meanwhile, a brake backup mechanism is arranged to provide corresponding functions when the brake signal collector, the brake controller or the brake executing mechanism fails, so that the brake backup function in line control is realized, and the safety of the vehicle can be effectively ensured.
FIG. 3 is a flow chart of a vehicle braking method provided according to one embodiment of the present disclosure. The method can be applied to the vehicle brake system provided by any embodiment of the disclosure. The vehicle braking system comprises a braking signal collector, a braking controller, a braking executing mechanism and a braking backup mechanism. As shown in fig. 3, the method may include steps 31 to 34.
In step 31, a braking signal is acquired during the running of the vehicle.
If the brake signal collector does not fail, the brake signal collector collects the brake signal, and if the brake signal collector fails, the brake signal is obtained from the brake backup mechanism.
The brake backup mechanism can comprise a backup brake signal collector which can provide the same function as the brake signal collector. Therefore, if the brake signal collector does not fail, the brake signal can be obtained from the brake signal collector, and if the brake signal collector fails, the brake signal can be obtained from the backup brake signal collector.
In step 32, a brake control command is generated based on the brake signal.
And if the brake controller fails, the brake control command is generated by the brake backup mechanism.
A backup brake controller may be included in the brake backup mechanism and may provide the same functionality as the brake controller. Thus, if the brake controller is not disabled, the brake controller generates a brake control command, and if the brake controller is disabled, the backup brake controller generates a brake control command.
In step 33, a brake control command is sent to the brake actuator if the brake actuator has not failed.
In step 34, in the event of a failure of the brake actuator, a brake control command is sent to the brake backup mechanism.
The brake backup mechanism may include a backup brake actuator that provides the same functionality as the brake actuator. Therefore, if the brake executing mechanism does not fail, the brake executing mechanism responds to the brake control command, and if the brake executing mechanism fails, the backup brake executing mechanism responds to the brake control command.
Through the technical scheme, the brake backup mechanism is arranged, and a corresponding function is provided when the brake signal collector, the brake controller or the brake executing mechanism fails, so that the brake backup function in line control is realized, and the safety of a vehicle can be effectively ensured.
