Below in conjunction with accompanying drawing, describe according to the control method of the auto pedal of the vehicle of the embodiment of the present invention, system and there is the vehicle of this system.
Fig. 1 is the diagram of circuit of the control method of the auto pedal of vehicle according to an embodiment of the invention.As shown in Figure 1, the control method of the auto pedal of vehicle, comprises the steps: according to an embodiment of the invention
Step S101: control auto pedal and stretch or retract.Wherein, when vehicle parking and car door opening, auto pedal stretches out for passenger and gets on and off conventionally.When Vehicle Driving Cycle and/or closing of the door, it has been generally acknowledged that passenger's demand that do not get on and off, auto pedal is retracted.
Particularly, as shown in Figure 2, carry out gate signal detection (being detecting gate signal), when gate signal is high level, door is opened (opening the door), now, if judgement auto pedal (abbreviation pedal) is retracted mode (being that pedal closes), control pedal stretches, when if gate signal is low level, door is closed (closing the door), now, if judgement pedal is extended configuration (being that pedal is opened), control pedal is retracted.
Step S102: when auto pedal stretches or retracts, judge according to the current location of auto pedal and current drive current whether auto pedal encounters obstacle in the process that stretches or retract.
As a concrete example, the current location of auto pedal can be detected and be obtained by Hall element, and for example, auto pedal is when moving to diverse location, Hall element senses changes of magnetic field, thereby according to the difference in the magnetic field sensing, can detect the position of auto pedal.The current drive current of auto pedal can be detected and be obtained by current sensor.
Step S103: if current location is not target location and current drive current not to be greater than anti-pinch and to detect electric current, confirm that auto pedal encounters obstacle in the process that stretches or retract.
The auto pedal of take is example by extended configuration to retracted mode motion, for example, when auto pedal is moved to complete retracted position (being target location) by full extended position (being reference position), obtain in real time current location and the current drive current of auto pedal, as shown in Figure 3, using hall signal number as the signal that reflects automobile pedal position, detect the hall signal number of receiving, if hall signal number reaches predetermined value, represent that auto pedal has arrived target location, continue to detect current drive current, if the current drive current detecting is greater than the default electric current that stops, stop pedal, illustrate that auto pedal moves to complete retracted position by full extended position, in motion process, auto pedal is not encountered obstacle but normally operation.
If hall signal number does not reach predetermined value, and the current drive current detecting is greater than anti-pinch and detects electric current, illustrate that auto pedal encounters obstacle in the process of retracting, and in actual applications, anti-pinch detection electric current is less than the default electric current that stops.
The current drive current detecting if hall signal number does not reach predetermined value is normal current, illustrates that auto pedal is just at regular event.
Step S104: when auto pedal is encountered obstacle in the process of stretching, extension or retraction, after control auto pedal counter motion preset distance, stop, and delay scheduled time.
Shown in Fig. 3, while encountering obstacle in the process that auto pedal is being retracted, control auto pedal (being direction of extension) motion predeterminable range (can be for example a certain less distance) round about, and time delay is but is not limited to 2 seconds.
Step S105: repeated execution of steps S101 to step S104 until in default cycle number auto pedal stretch or be retracted to described target location, otherwise control auto pedal, be back to reference position.
Shown in Fig. 3, after delay time finishes, again attempting controlling auto pedal retracts, for example, after trial pre-determined number (3 times), auto pedal still cannot move to target location, control auto pedal and be back to reference position, illustrate that obstacle exists all the time, auto pedal can not normally run to target location.
It should be noted that, whether whether auto pedal detects while having obstacle and processing mode and auto pedal to be moved to retracted mode by extended configuration when being moved to extended configuration by retracted mode is detected and has the principle of obstacle and processing mode similar, in order to reduce redundancy, do not repeat.
According to the control method of the auto pedal of the vehicle of the embodiment of the present invention, according to the current location of the auto pedal detecting and current drive current, for example when being greater than a certain default anti-pinch, the current drive current of judgement detects electric current, just confirm that auto pedal runs into obstacle, thereby can be timely, judge exactly auto pedal and whether run into obstacle in the process that stretches or retract, and after judgement runs into obstacle, can promptly control auto pedal to the reversing sense rear time delay Preset Time of certain a bit of distance that moves, like this, can prevent that obstacle from blocking, and can make obstacle remove smoothly, thereby avoiding dangerous occurs, improve the safety of vehicle.In addition, auto pedal attempt moving to target location several times after, if obstacle exists all the time, control auto pedal correcting action, avoid to target location motion, cannot arriving target location all the time and causing auto pedal or the failsafety (as driven the motor rotation blockage of auto pedal motion burn) relevant to auto pedal owing to controlling auto pedal, improve the service life of auto pedal and parts relevant to auto pedal.
Due under mal-condition, may cause that auto pedal is locked can not move in certain position, for example in cold winter, owing to freezing, cause auto pedal to freeze and can not move.Therefore, the method for the embodiment of the present invention is when auto pedal stretches or retracts, further comprising the steps of:
1, according to the current location of auto pedal and current drive current, judge whether auto pedal cannot move.
If 2 current locations are greater than anti-pinch detection electric current in reference position and current drive current, judge that auto pedal cannot move.
3, when auto pedal cannot move, forbidding auto pedal function.
As a concrete example, shown in Fig. 3, when demand motive brake pedal moves, for example, by electric motor starting brake pedal setting in motion, now, if do not receive that hall signal or hall signal number are very little, but the current drive current detecting is greater than anti-pinch and detects electric current, not motion of auto pedal is described, motor can not drive auto pedal motion, can stop motor, and starter motor trial driving auto pedal motion again after time delay a period of time (as 5 seconds), for example after attempting three times, still cannot drive auto pedal motion, judge auto pedal cannot move (for example freezing), now, can forbid auto pedal function makes it enter lock-out state.
As mentioned above, after forbidding auto pedal function, even meet auto pedal moving condition as described in step S101, can not respond yet.Do like this in the situation that of can cannot moving but meet auto pedal moving condition freezing such as auto pedal, avoid driving the actuator of auto pedal motion to start (as motor) and can not drive auto pedal motion to cause actuator or auto pedal damage etc., the service life of effective Hoist braking pedal, simultaneously, than in existing mode by M/C to start or forbidding auto pedal function, there is intelligentized advantage, in addition, for example, when auto pedal freezes, if forget M/C forbidding auto pedal function, may cause actuator or auto pedal to damage, therefore, the method of the embodiment of the present invention can avoid actuator or auto pedal to damage effectively.
As shown in Figure 4, if while attempting driving auto pedal motion, current drive current is less than anti-pinch and detects electric current, judge that auto pedal can move, now, can start auto pedal function, thereby when meeting auto pedal moving condition, control auto pedal motion.
In Vehicle Driving Cycle process, the method can also be controlled auto pedal function according to speed of a motor vehicle etc., as shown in Figure 5, for example, comprises:
1,, when Vehicle Driving Cycle, according to the speed of a motor vehicle, judge whether to forbid auto pedal function.
If 2 speed of a motor vehicle are greater than the first preset vehicle speed and auto pedal in complete retracted position, forbid auto pedal function, otherwise control auto pedal, move to after complete retracted position forbidding auto pedal function.
If 3 speed of a motor vehicle are less than the second preset vehicle speed and judge when auto pedal can move, enable auto pedal function, wherein, the second preset vehicle speed is less than the first preset vehicle speed.
For example: by CAN bus, obtain current vehicle speed information, when the speed of a motor vehicle is greater than prohibition vehicle speed (the first preset vehicle speed, the speed of a motor vehicle while needing to forbid auto pedal function, as 8,000 ms/h) time, read auto pedal Status Flag, if auto pedal Status Flag is stretching, extension (if auto pedal is extended configuration), the auto pedal that bounces back, and upgrade auto pedal Status Flag.After auto pedal bounces back completely (being that auto pedal is in complete retracted position), forbidding auto pedal function.
When being less than, the speed of a motor vehicle enables the speed of a motor vehicle (i.e. the second preset vehicle speed, can start the speed of a motor vehicle of auto pedal function, as 5,000 ms/h) time, read automobile pedal switch Status Flag, if this is masked as, enable (starting electric treadle function), can determine whether and stretch or retraction auto pedal according to vehicle door status etc.Hence one can see that, when the speed of a motor vehicle is higher (as 8,000 ms/h), illustrates that automobile normally travels, and now, forbidden auto pedal function, to occur beyond preventing, guarantees vehicle safety.When the speed of a motor vehicle is compared with hour (as 5,000 ms/h), namely vehicle stops or during very little speed low speed driving, may there is the demand of getting on and off in explanation, therefore start auto pedal function, with when passenger need to get on and off, auto pedal can stretch smoothly or bounce back, and facilitates passenger to get on and off.
In existing mode, having some is by the forbiddings such as vehicle door status (as whether latched) or startup auto pedal function, if during Vehicle Driving Cycle, do not latch, even if vehicle is in the process of running at high speed, auto pedal function does not have disabled yet, thereby once auto pedal stretches in the process of running at high speed, may cause danger.Therefore, the method for the embodiment of the present invention determines whether forbidding auto pedal function by the speed of a motor vehicle, and lifting vehicle safety effectively, avoids dangerous generation.
In addition, in existing mode, although also having some is to determine whether forbidding auto pedal function by the speed of a motor vehicle, but be all that a velocity amplitude is set, when the speed of a motor vehicle is forbidden auto pedal function higher than this velocity amplitude, lower than this velocity amplitude, start auto pedal function, imagine, if the speed of a motor vehicle is hovered upper and lower at this velocity amplitude, constantly conversion between startup and forbidding of auto pedal function, constantly start at short notice and forbid the damage that may cause vehicle associated components, affecting the service life of vehicle.Therefore, the method for the embodiment of the present invention can also improve the service life of vehicle effectively.
As shown in Figure 6, when passenger gets on and off under the darker environment of light (as night), be difficult to see clearly the situation of underfooting, easily cause danger, therefore, the vehicle of the embodiment of the present invention also comprises courtesy light, correspondingly, the method also comprises: according to the state of auto pedal and Illumination intensity, judge whether to start courtesy light, be less than default Illumination intensity, control pedal illumination lamp ignition if the state of auto pedal is extended configuration and Illumination intensity.That is to say, auto pedal stretches or has reached full extended position, passenger's demand that gets on and off is described, and when light is darker, for passenger can clearly see auto pedal, can illuminate auto pedal by courtesy light, like this, passenger just can successfully get on and off by auto pedal, promotes user and experiences also effectively lifting vehicle safety.
