Describe according to the auxiliary braking controlling method of the vehicle of the embodiment of the present invention, system and the vehicle with this system below in conjunction with accompanying drawing.
Fig. 1 is the flow chart of the auxiliary braking controlling method of vehicle according to an embodiment of the invention.As shown in Figure 1, the auxiliary braking controlling method of vehicle, comprises the steps: according to an embodiment of the invention
Step S101: the accelerator pedal signal and the brake petal signal that obtain vehicle.
Wherein, accelerator pedal signal is such as the opening amount signal of gas pedal, and brake petal signal is such as the opening amount signal of brake petal.In one embodiment of the invention, such as: the accelerator pedal signal of vehicle detects through but not limited to accelerator pedal position sensor and obtains, and brake petal signal detects through but not limited to brake pedal position sensor and obtains.
Step S102: judge the state of gas pedal and the state of brake petal according to accelerator pedal signal and brake petal signal.Such as, judge the aperture of gas pedal according to accelerator pedal signal, judge the aperture of brake petal according to brake petal signal.
Step S103: if the state of gas pedal be releasing orientation and the state of brake petal for stepping on state, then detect the current speed of a motor vehicle of vehicle further.Wherein, preset vehicle speed obtains based on experience value, and such as preset vehicle speed is but is not limited to 30,000 ms/h.
That is, if the aperture of gas pedal be zero or be less than some less values time, think that driver does not step on the throttle pedal, now, can judge that the state of gas pedal is releasing orientation, otherwise then think that the state of gas pedal is for stepping on state.In like manner, if the aperture of brake petal be zero or be less than some less values time, think that driver does not step on brake petal, now, can judge that the state of brake petal is releasing orientation, otherwise then judge that the state of brake petal is as stepping on state.
Step S104: if the current speed of a motor vehicle of vehicle is greater than preset vehicle speed, then regulate the aperture size of the exhaust valve of the motor of vehicle to carry out auxiliary braking by motor to vehicle.Specifically, comprise the following steps:
Step S1041: the degree of depth obtaining brake petal according to brake petal signal.
Step S1042: according to the aperture size of the depth adjustment exhaust valve of brake petal to change the braking force of auxiliary braking while carrying out auxiliary braking by motor to vehicle according to the aperture size of exhaust valve, wherein, the degree of depth of brake petal is larger, and the aperture of exhaust valve is less.
That is, the degree of depth that brake petal is operated is larger, then illustrate that the braking force required for vehicle is larger, therefore, when required braking force is larger, by making to have started the aperture of the exhaust valve of cylinder less, such as control the aperture reduction of exhaust valve by camshaft adjuster or close exhaust valve etc., the resistance being compressed air when now engine piston is up in cylinder is larger, make engine piston up slower in cylinder, thus change the braking force of auxiliary braking while making motor itself produce auxiliary braking.
The working principle of the auxiliary braking method of the vehicle of inventive embodiments is described in detail.
When the automobile travelled needs to slow down or brake, first driver can unclamp gas pedal, allows vehicle itself continue to slide, and such as: if when having traffic light or obstacle above, then goes braking by touch on the brake (brake petal), allows the vehicle travelled stop.The auxiliary braking method of the vehicle of the embodiment of the present invention, can help driver to need to carry out auxiliary braking by motor itself during braking, thus reduce apply the brakes braking.
When gas pedal is unclamped, gas pedal is not opened, if brake petal is opened, is namely operated, then think that driver exists braking requirement, by reducing the aperture of exhaust valve or closing joint exhaust valve, and controls oil sprayer not to oil spout in engine cylinder.Motor to complete in a work cycle because do not have oil spout, would not produce power and go to promote piston operation, thus reduce the speed of car.
When gas pedal is unclamped and brake petal brakes, carry out judging whether to carry out auxiliary braking according to vehicle speed signal.Such as: the object of the fast long response time current driver's braking of the speed of a motor vehicle, if unclamp throttle when the speed of a motor vehicle is slower, there are slight skidding or not braking, illustrate that driver is at coasting vehicle.If unclamp throttle when the speed of a motor vehicle is very fast, and with skidding, illustrate that driver needs braking.Each vehicle condition is different, and the parameter of the concrete speed of a motor vehicle and the degree of depth of gas pedal obtain after needing to carry out actual demarcation.
As shown in Figure 2, as a concrete example, suppose preset vehicle speed be 30 kms/time, and divide 30% respectively with the brake petal degree of depth, 60%, 100% 3 degree of depth is described.When brake petal is operated, the current speed of a motor vehicle of vehicle lower than 30 kms/time, illustrate that driver need normally slide, now exhaust valve do not cut out, namely do not carry out auxiliary braking.If the speed of a motor vehicle higher than 30 kms/time, and when brake petal is operated, need to carry out auxiliary braking, if the degree of depth of brake petal is 30%, then 30% closedown carried out to exhaust valve; If the degree of depth of brake petal is 60% time, 60% closedown is carried out to exhaust valve, if the degree of depth of brake petal is 100% time, contract fully is carried out to exhaust valve, like this when being vented, it is in different size that engine exhaust port is closed, and intake valve is in closed condition, when engine piston is up, be compressed the resistance of air, engine speed is declined, thus carry out auxiliary braking by motor itself, reach the object of regulation speed.
Specifically, shown in 2, the auxiliary braking controlling method of the vehicle of the embodiment of the present invention comprises the following steps:
Step S201: when clutch does not unclamp, whether gas pedal unclamps.(judging namely be in the condition of operation at clutch under whether gas pedal unclamps), if unclamped, then performs step S202, otherwise performs step S203.
Step S202: normal vehicle operation or acceleration, without the need to braking.
Step S203: judge the brake petal degree of depth, if the brake petal degree of depth is zero, then performs step S204, otherwise when the brake petal degree of depth is 30%, perform step S205, when the brake petal degree of depth is 60%, perform step S208, when the brake petal degree of depth is 100%, perform step S211.
Step S204, vehicle deceleration (the natural taxiing procedures as the vehicle that vehicle is in when not refueling), without the need to auxiliary braking.
Step S205: whether the speed of a motor vehicle is greater than 30,000 ms/h, if otherwise perform step S206, otherwise perform step S207.
Step S206: vehicle deceleration, without the need to auxiliary braking.
Step S207: auxiliary braking is carried out in exhaust valve closing 30%.
Step S208: whether the speed of a motor vehicle is greater than 30,000 ms/h, if otherwise perform step S209, otherwise perform step S210.
Step S209: vehicle deceleration, without the need to auxiliary braking.
Step S210: auxiliary braking is carried out in exhaust valve closing 60%.
Step S211: whether the speed of a motor vehicle is greater than 30,000 ms/h, if otherwise perform step S212, otherwise perform step S213.
Step S212: vehicle deceleration, without the need to auxiliary braking.
Step S213: auxiliary braking is carried out in exhaust valve closing 100%.
According to the auxiliary braking controlling method of the vehicle of the embodiment of the present invention, by closing or reduce the aperture of exhaust valve, piston is made to be subject to the back pressure of cylinder charge, hinder the running of motor, motor itself is allowed to produce braking, thus frequent apply the brakes dish can be reduced go braking, improve vehicle travel in Security, and effectively promote the life-span of brake.
The method of the embodiment of the present invention judges vehicle-state by the brake petal signal that gathers and accelerator pedal signal, the data (as brake petal signal and accelerator pedal signal) gathered are accurate, precision is high, auxiliary braking control is carried out on this basis according to vehicle-state, frequent apply the brakes dish can be reduced and go braking, improve the Security in vehicle traveling, and effectively promote the life-span of brake.Such as: at a high speed or the emergency brake of vehicle of fast running time, motor receives instruction and cuts out exhaust valve, and piston is subject to the back pressure of gas, hinder the running of motor, allow motor itself produce braking, allow vehicle stop fast, decrease the distance of brake and the use of brake disc.Automobile is when very long ramp up-downgoing, motor receives 30% or 60% are carried out in instruction cut out to exhaust valve, decreasing driver uses main car braking system to cause the temperature of break to raise frequently, damage, reduce dangerous or serious accident in vehicle traveling, improve vehicle stability in the process of moving.
