and S103, if the safety condition of the vehicle is non-safety, at least controlling a user interface to display prompt information.
In step S101, the sensor on the vehicle may detect the road condition information of the road where the vehicle is located and the first state information of the vehicle itself. For example: the vehicle is provided with an acceleration sensor, a longitudinal acceleration signal is detected by the acceleration sensor, and the size of the slope can be calculated according to the signal and a wheel Speed signal, wherein the signal can be provided by an Electronic Stability Program (ESP)/Electronic Stability Controller (ESC), an Electronic Stability Controller (EPB) integrated acceleration sensor or other controllers.
In step S012, it may be determined whether the current parking state of the vehicle is safe only according to the traffic information, or the parking safety of the vehicle is determined only according to the first state information, or the parking safety of the vehicle is determined according to the traffic information and the first state information at the same time. The safety condition of the vehicle includes safe and unsafe, among others. It will be appreciated that it is more reliable to determine the safety condition of the vehicle based on both the road condition and the first status information.
In step S103, if the vehicle safety state is safe, the user interface does not need to be controlled to display the prompt information, and the user interface may only display the function page; and controlling the user interface to display prompt information only when the vehicle safety state is unsafe.
The prompt message includes but is not limited to text message, icon message or color message, and the prompt message may be prompted in a flashing state. It can be understood that the prompt message may also have a warning effect, and may also be used as a warning message. Generally, the stronger the prompt effect of the prompt information on the user, the better the warning effect.
Besides controlling the user interface to display the prompt information, the warning lamp can be controlled to emit light or the loudspeaker can be controlled to sound. The reminding function is enhanced by light, sound and other prompt messages.
A User Interface (also called a human-computer Interface) refers to a medium for interaction and information exchange between a system and a User, and it realizes conversion between an internal form of information and a human-acceptable form. The user interface includes a display screen through which the prompt information may be displayed.
When applied to a vehicle, the user interface includes a center console or dashboard located in the cab, etc.
In some embodiments, if the safety condition of the vehicle is non-safety, at least controlling the user interface to display a prompt message includes: and displaying different prompt messages according to different reasons of the safety condition.
Further, reasons for safety conditions include: road conditions and/or vehicle conditions. Further, the road conditions include: the road gradient is not less than a first preset value; and/or, the vehicle condition comprises at least one of: the driving mode of the transfer case is in a four-wheel driving mode, and the transmission gear is in a forward gear or a reverse gear.
For example: when the vehicle is parked on a road with a large gradient, the prompt information may be: the current gradient is large, and parking is risky. The prompt may be "please engage neutral or P-range" when the drive mode is in the four-wheel drive mode and the transmission gear is in the forward range.
In some embodiments, a control method of electronic parking includes: acquiring electronic parking and vehicle state information (i.e., first state information); displaying the acquired electronic parking and vehicle state information through a human-computer interaction interface; if the vehicle state information indicates that the vehicle state does not accord with the safety condition, generating prompt information or alarm information, and displaying the prompt information on a prompt information display interface or displaying the alarm information on an alarm information display interface; and controlling to exit the prompt information display interface or the alarm information display interface and enter a function interface according to the prompt information or the alarm information. The invention can clearly feed back the electronic parking state information to the driver, can be applied to any combination instrument and has strong practicability.
For an automobile applying electronic parking, a man-machine interaction interface control method is more important. The man-machine interaction interface provided by the embodiment of the invention can clearly feed back the state information of electronic parking of the vehicle to a driver, when the electronic parking starting condition is not met due to the operation of the driver, the man-machine interaction interface generates prompt information, and the driver realizes an expected function according to the operation of the prompt information; when the electronic parking state does not accord with the safety condition, the human-computer interaction interface generates prompt information or alarm information to help a driver to make a correct judgment.
Therefore, according to the electronic parking control method provided by the embodiment of the invention, when the vehicle is determined to be in an unsafe condition according to the road condition information and/or the first state information of the vehicle, the prompt information is displayed on the user interface, so that a prompt or warning effect is provided for users such as a driver, and the users can adopt corresponding measures according to the prompt information, so that the parking safety is improved.
In other optional embodiments, the traffic information includes: road grade; and/or;
the first state information of the vehicle includes at least one of: drive mode of the transfer case, transmission gear or vehicle fault condition.
It will be appreciated that the first status information may also include other information, such as: engine torque or mileage information, etc.
Generally, the larger the road gradient is, the more dangerous the parking is, and by detecting the road gradient and determining the safety condition of the vehicle according to the road gradient, the parking safety of the vehicle is further improved.
In other optional embodiments, the determining the safety condition of the vehicle in the parking state according to the road condition information and/or the first state information of the vehicle includes:
determining that the safety condition of the vehicle is unsafe when the road gradient is not less than a first preset value;
and/or the presence of a gas in the gas,
the driving mode of the transfer case is in a four-wheel driving mode, and/or the transmission gear is in a forward gear or a reverse gear, and the safety condition of the vehicle is determined to be unsafe.
Where the gradient is (difference in elevation/course) x 100%, and the first preset value is, without limitation, 30% or more. For example: at a grade of 35%, 40%, 45% or 50%, it may be necessary to indicate to the user that parking is unsafe.
In some embodiments, the vehicle is an off-road vehicle frequently, the off-road condition is complex, a driver often drives on a slope of 30% or more (a slope exceeding the national regulation requirement), the control method of electronic parking according to the invention designs an "EPB 1_ W _ Parkingslope" monitoring signal, the signal comprises two values of "no warning" and "warning", when the driver parks on a slope of 30% or more, "EPB 1_ W _ Parkingslope" signal value is set to "warning", an instrument control module receives the signal, and displays "the current slope is large, the parking is risky" through a human-computer interaction interface so as to prompt the driver to avoid the risk.
The transfer case drive mode is different and the clamping force required to hold the vehicle stationary is different. When the driving torque of the driving mode is large, the engine torque is large, the clamping force required by the vehicle is large, the situation that the driving torque cannot be overcome by the clamping force easily occurs, the vehicle cannot be stopped is caused, and the safety risk of parking the vehicle is increased. Therefore, the safe condition of the vehicle in parking can be effectively determined according to the driving mode of the vehicle transfer.
In some embodiments, for an automobile with a four-wheel drive transfer, when the transfer is in 4L mode (4L mode with amplified torque capability), the transmission is in D or R, if electronic parking only monitors grade and not transfer drive mode, EPB clamp force is insufficient to overcome the drive torque in 4L mode, resulting in the vehicle not being able to remain stationary, there is a risk of rolling down a hill on a hill or rolling down a flat road. The control method of the electronic parking is designed for monitoring the driving mode of the four-wheel drive transfer case, and simultaneously applies corresponding clamping force by combining the monitoring of the ramp, the engine torque and the transmission gear, so that the vehicle can keep a static state on a flat road or a ramp, and the parking safety is ensured. Meanwhile, the control method of the invention designs EPB1_ St _4 LPArkingWarnng signal real-time monitoring, the signal is divided into two values, when a driver stays in a 4L mode for a long time and a transmission stays in a D gear or an R gear and keeps a parking state, as the driving force is large, in order to avoid damage to a parking mechanism, a prompting signal EPB1_ St _4 LPArkingWarnng value sends 'Warnng (alarm)', an instrument control module receives the signal, and displays 'if parking for a long time, please engage in a neutral gear or a P gear' through a man-machine interaction interface for prompting the driver to carry out standard operation in time, so as to ensure the use safety of an automobile; in other cases, EPB1_ St _4LParkingWarning signals "Normal", and the human interface defaults to no prompt.
In other optional embodiments, the determining the safety condition of the vehicle in the parking state according to the road condition information and/or the first state information of the vehicle further includes:
and determining that the safety condition of the vehicle is unsafe when the parking time is not less than a second preset value.
Without limitation, the second preset value may be 5min, 10min, 30min, 60min, 80min, or the like.
In practical application, under the condition that the parking time is short (the parking time is less than the second preset value), even if the road gradient of the vehicle is not less than the first preset value in the parking state; and/or, the first state information of the vehicle is at least one of the following conditions: the driving mode of the transfer case is in a four-wheel driving mode, the gear position of the transmission is in a forward gear or a reverse gear, and the safety condition of the vehicle can still be determined to be safe. If the parking time in the parking state is longer, for example, the parking time reaches a second preset value or exceeds the second preset value, the safety state of the vehicle is determined to be unsafe. The determination of the vehicle safety condition is more accurate and more flexible, and is beneficial to improving the user experience.
In other optional embodiments, the electronic parking control method further comprises:
determining the safety level of the vehicle according to the road condition information and/or the first state information of the vehicle;
and controlling the user interface to display different prompt messages for different security levels.
In this embodiment, the prompt information displayed on the control user interface may be a parking state of the vehicle, or may be a non-parking state, for example: the vehicle running state.
In some embodiments, the safety level of the vehicle in the parking state or the driving state is determined according to the road condition information and/or the first state information of the vehicle; and controlling the user interface to display different prompt messages for different security levels. The safety condition of the vehicle is detected by simultaneously detecting the running state and the parking state, so that the use safety of the vehicle is further improved.
In some embodiments, the prompt messages are arranged in descending order according to the security level, and the prompt effect of the prompt message corresponding to the high security level is better than that of the prompt message corresponding to the low security level. For example: if the electronic parking system is defective, the defect level can be monitored via the signal EPB1_ St _ WarningLamp, and different signal values can be sent depending on the defect level. When all functions are failed due to faults, the EPB1_ St _ WarningLamp sends a signal value 'high warning', a man-machine interaction interface lights a warning lamp, and 'EPB faults, please stop immediately and repair immediately' are displayed; when the fault only causes partial secondary function failure, EPB1_ St _ WarningLamp sends a signal value "warning", and the human-computer interface lights up a warning lamp and displays "EPB fault, please repair in time". The man-machine interaction interface displayed in a grading way is more humanized and more practical.
In other optional embodiments, the electronic parking control method further comprises:
releasing the parking function to start the vehicle;
acquiring second state information of the vehicle;
when the second state information of the vehicle is determined not to meet the preset requirement, at least displaying prompt information on a user interface; and/or the presence of a gas in the gas,
the electronic parking control method further includes:
releasing the parking function to perform manual parking;
acquiring third state information of the vehicle;
and when the third state information of the vehicle is determined not to meet the preset requirement, at least displaying prompt information on a user interface.
In some embodiments, the second status information comprises seat belt wear information; when the safety belt is not worn, for example, the buckle of the safety belt is not positioned in the jack on the vehicle seat, the user interface is controlled to display prompt information. The prompt message at this time may be: please tie the safety belt. For example: when a driver intends to release parking in an automatic release mode, the safety belt is not fastened in an EPB clamping state and the automobile starts, the EPB cannot be automatically released, an EPB ECU (Electronic Control Unit, also called as an on-board computer, EPB ECU also called as an EPB controller) sends a signal EPB1_ Disp _ WithoutSeatBelt value "fault", the combination meter receives the signal, and the man-machine interaction interface prompts "please fasten the safety belt".
In some embodiments, the third status information includes status information of the brake switch. And if the parking function is not available, if the brake pedal is in a closed state, that is, the brake pedal is not stepped on by the driver is detected, and at the moment, the release condition is not met, and the user interface is controlled to display prompt information. For example: when a driver intends to release parking through manual operation, an EPB button is pressed, a brake pedal is not pressed, the release condition is not met and release can not be performed, the EPB ECU sends a signal EPB1_ Disp _ WithoutBase value 'fault', the combination meter receives the signal, and the man-machine interaction interface prompts 'brake pedal is pressed at the same time'.
The respective signals received by the EPB controller in parking are described in detail below. As shown in FIG. 2, the EPB static park function inputs include: brake switch signal (BLS), wheel speed/wheel speed Pulse signal (WSS/WSS Pulse), transmission Gear signal (TCM Gear), EPB switch signal, four-wheel drive signal (i.e. the drive mode of the transfer case, including 2H/4H/4L), safety belt Signal (SDM), mileage signal (Odometer) or power mode signal (CAPE), etc.
Among them, EMS (Engine Management System) in fig. 2 is concerned with managing torque/rotational speed/accelerator pedal and the like. Electronic stability program block (ESP) relates to master cylinder pressure/EPB dynamic deceleration response/clamp release request, etc.
Tool relates to diagnostic input and response, etc.
The brake light relates to the indication when the CDP/RWU/DSD is in operation. Among them, CDP (Controller cancellation locking), RWU (rear wheel anti-locking), and DSD (Direct Stream Digital coding).
The signal input and output of the EPB controller rely on CAN or hardwire. Wherein, CAN means bus
Electronic parking function signal input: a longitudinal acceleration signal (ramp signal), a transfer case drive mode signal, a gear signal, an engine torque signal, an accelerator opening signal, a vehicle speed signal, a wheel speed signal, an EPB switch signal.
Wherein: longitudinal acceleration signal: the ramp size is calculated from the signal and the wheel speed signal, which may be provided by an esp (esc), an EPB integrated acceleration sensor, or other controller.
Transfer case drive mode signal: the signal at least comprises three modes of 2H, 4H and 4L. Provided by a transfer case switch or provided after conversion by other controllers;
gear signals: provided by TMS or EMS;
engine torque signal: provided by the EMS;
accelerator opening degree signal: judging the intention of the driver according to the signal, and providing the intention by EMS;
vehicle speed signal, wheel speed signal: judging whether the vehicle is in a static state or not according to the vehicle speed/wheel speed signal, wherein the signal is provided by ABS/ESP (ESC);
EPB switching signal: the signal comprises at least 3 signal values of clamping, releasing and neutral.
EPB calipers: including EPB left side back calliper, and EPB right side back calliper, be connected with the wheel module. For clamping status feedback.
When the transfer case is in a 4L mode, after the EPB applies the maximum clamping force, if the transmission is detected to be in a D gear or an R gear, in order to prevent the EPB calipers from being damaged, the EPB ECU sends an EPB1_ St _4 LPArkingWarnng signal with a signal value of 'Warnng', and the combination meter receives the signal and displays 'please put in a neutral gear or a P gear if parking for a long time through a man-machine interaction interface'.
When a driver parks on a slope of 30% or more, the EPB ECU sends an 'EPB 1_ W _ Parkingslope' signal and a signal value 'warning', the combination meter receives the signal and displays 'the current slope is large and the parking is risky' through a man-machine interaction interface so as to prompt the driver to avoid the risks.
The EPB ECU sends different signal values for signals EPB1_ St _ WarningLamp according to fault levels, when the fault levels are monitored, different signal values are sent according to the fault levels, when the faults cause the failure of all functions, the EPB1_ St _ WarningLamp sends a signal value of 'high warming', a human-computer interaction interface lights a warning lamp, and simultaneously displays 'EPB faults, please stop immediately and maintain immediately'; when the fault only causes partial secondary function failure, the EPB1_ St _ WarningLamp sends a signal value of 'warming', the man-machine interaction interface lights a warning lamp, and simultaneously displays 'EPB fault, please repair in time'.
When the EPB ECU detects that two or more wheel speed sensors fail (no matter power-on or flameout, no matter pulling or not pulling the EPB switch), a signal EPB1_ St _ NoParkingWarnng sends a warning signal, the combination meter receives the signal, and the man-machine interaction interface displays 'if parking, please pull the EPB switch for a long time after flameout'; otherwise, the signal EPB1_ St _ NoParkingWarng sends normal, and the human-computer interaction interface has no prompt.
