Description

Motor vehicle
Technical field
The present invention relates to a kind of motor vehicle, relate in particular to and a kind ofly have in order to fuel saving and reduce the motor vehicle of the system of toxic emission with explosive motor.
Background technique
When stationary vehicle, engine idle produces unnecessary fuel consumption, and is the source that can avoid carbon dioxide and other toxic emissions.In fact, now, in some cases, when stationary vehicle, allow the engine long time idling be in violation of rules and regulations.
Being known that provides in order to stop and starting the vehicle control system of explosive motor (when defining chance and do like this) automatically, and present many manufacturers introduce the vehicle with this system.Yet more difficult realization starts to walk-shutdown system and cost height automatically in some power system combinations (powertrain combinations).For example for automatic transmission, to the demand requirement oil hydraulic pump maintenance running of speed changer transient response, for large-scale diesel engine, the high inertia of diesel engine requires more powerful system to guarantee quick response.
For being equipped with automatic stopping-starting system, engine stop-state can only continue by the definite finite time of the charged state of Vehicular battery.When tail-off, alternator no longer produces power, and the whole electrical load of vehicle (comprising ventilation, illumination, communication and amusement system (usually in tens of amperes of scopes)) must be kept by Vehicular battery.For guaranteeing to have enough electric charges in the battery to guarantee to restart fast motor, electric charge or Voltage threshold state are defined as usually, are lower than under the situation of this electric charge or Voltage threshold that motor is restarted automatically or the driver is restarted motor and to start battery charged again.
In the vehicle that is not equipped with automatic stopping-starting, just because motor does not cut out or because the sound and/or the vibration of motor, motor was in running when the driver can be appreciated that stationary vehicle.If vehicle stops in traffic or stop time prolongation for other reasons, usually for the driver,, be fuel saving if vehicle seems to want static a period of time after a few minutes, the driver kills engine.Yet the inventor recognizes that the driver forgets sometimes and kills engine.
In the vehicle that is equipped with automatic stopping-starting, when stationary vehicle motor through the halted state of being everlasting, imperceptible any engine sound of driver or vibration.Not all driver can recognize immediately: can not keep engine stop-state indefinitely.If the vehicle stop time prolongs, then start function to keep halted state (under the control of automatic stopping-starting control system), and excess drive person close and does not have automatic stopping-time of motor in the vehicle of starting system.Thereby require Vehicular battery to continue to keep whole vehicle load, and must restart motor so that battery is charged again, more fuel and produce toxic emission therefore burn when vehicle keeps static.Therefore, automatic stopping-starting has maximum benefit relatively concerning the endurance than short parking.The inventor has realized that for the vehicle that is equipped with automatic stopping-starting in fact long-term parking has negative net effect to fuel consumption and toxic emission.
Summary of the invention
At the one or more problems that exist in the correlation technique, the object of the present invention is to provide a kind of motor vehicle with explosive motor, these motor vehicle can stop for a long time and remind the driver to cut out ignition mechanism under the situation that the driver does not kill engine at vehicle.
Advantageously, provide a kind of driver's of encouragement fuel saving and reduce the motor vehicle of toxic emission.
According to a first aspect of the invention, a kind of motor vehicle are provided, comprise explosive motor and can be by the switch of automobile driver operation, this switch has first state that does not allow engine running and second state that allows engine running, wherein, vehicle also comprises indicator, if vehicle keeps the static and lasting scheduled time under the situation of second state at switch, this indicator alerting drivers should change over first state from second state with switch.
Should close vehicle by the indication driver, if the driver more may close ignition switch with fuel saving, reduce toxic emission and vehicle stop time and prolong then reduce the motor loss.
Suitably, the scheduled time is three minutes or is less than three minutes.
Advantageously, motor also comprises can be operated stopping the control system with ato unit automatically, and the scheduled time is that control system has started automatically and keeps after the engine stop-state three minutes or still less.
Preferably, indicator comprises visual display unit.
Preferably, indicator comprises the touch device.

According to a second aspect of the invention, a kind of method of warning motor vehicle operator is provided, these motor vehicle comprise explosive motor and the exercisable switch of driver, this switch has first state that does not allow engine running and second state that allows engine running, wherein, described method comprises the steps:
When monitoring vehicle becomes during at second state static at switch;
Measuring vehicle switch during at second state vehicle how long staticly keep; And
After switch had kept the static and lasting scheduled time during in operating condition, alerting drivers changed over first state with switch from second state at vehicle.
According to the present invention, after the scheduled time, close igniting in stationary vehicle by alerting drivers, thereby, the motor loss that unnecessary engine idle causes when having saved fuel, reduced toxic emission and having reduced owing to stationary vehicle.
Description of drawings
Now the present invention is described with the by way of example of reference accompanying drawing, in the accompanying drawing:
Fig. 1 is the block diagram according to motor vehicle of the present invention; And
Fig. 2 shows the flow chart according to the method in order to the driver that warns motor vehicle shown in Figure 1 of the present invention.
Embodiment
Referring to Fig. 1, show the motor vehicle 1 that have by the explosive motor (or internal-combustion engine) 3 of control system control, this control system comprises the ECU (Electrical Control Unit) (ECU) 5 that receives input from key-operated ignition switch 7.Ignition switch 7 is in order to the overall operation of control motor 3.That is, when ignition switch 7 during in first " closing " position, motor 3 can not turn round, and when ignition switch 7 during in second " opening " position, motor 3 can turn round.Ignition switch 7 can also comprise in order to manually boot the 3rd instantaneous position of motor 3.Should be appreciated that other devices such as button, rocking bar or other type of switch also can be used to provide these functions, the present invention is not limited to the use ignition switch.
ECU 5 provides output to driver's indicator, and this indicator comprises the display device 9 on the Vehicular instrument panel.Should be appreciated that, can use any type of display device, such as the special-purpose beacon that only is used for following purpose and/or as the sounder of the part of vehicle amusement system or only be used for special-purpose sounder of following purpose or touch screen, the present invention is not limited to and uses display device 9.
For the conventional truck that does not possess parking-starting function, the endurance that ECU 5 monitoring vehicles are static.Although because the driver does not kill engine or because the sound and/or the vibration of motor, motor was in running when he can recognize stationary vehicle, and the driver still may forget and kills engine if vehicle stops for a long time.In this case, if vehicle ignition switch 7 is static and keeps the scheduled time that for example 3 minutes, then ECU provided an output to come to show the suggestion that close igniting to the driver to display device 9 when second " opening " position.When the driver noticed this suggestion, he can determine it is to accept a proposal and turn-off ignition switch 7, or may ignore this suggestion owing to soon starting once more.
If the driver turn-offs ignition switch 7, motor will stop, thus fuel saving, unnecessary engine idle causes when reducing toxic emission and reducing owing to stationary vehicle motor loss.
When making vehicle keep static reason to finish, the same driver is with ignition switch 7 ato units, to continue his/her stroke when beginning with route.
On some vehicles, ECU 5 can comprise parking-starting function, and this parking-starting function is in order to stop and starting explosive motor 3 automatically defining when chance is so done, with fuel saving and reduce toxic emission.In this case, when one or more predetermined motors stopped to occur with starting state, ECU 5 optionally stopped under the situation that does not have the driver to get involved and ato unit 3.When stationary vehicle, such as stopping at the traffic lights place, such halted state has just appearred.Usually, this halted state continues several seconds to a few minutes and allows vehicle to move once more up to traffic signals, then when ECU 5 perceive the driver when being ready to once more actuating vehicle ECU 5 will automatically restart motor 3.
Yet halted state may last much longer in some cases, the parking situation that causes under the situation that road construction place stops or owing to the accident on the road ahead such as vehicle.In this case, ECU 5 will make motor 3 keep halted states, and Vehicular battery will continue to keep whole vehicle electrical power load, when being ready to start vehicle once more or when another situation of ato unit takes place such as the driver till.Yet the endurance that ECU 5 monitoring vehicles are static, if the endurance surpasses the scheduled time (for example 3 minutes), ECU 5 provides output to show the suggestion that close ignition mechanism to the driver to impel display device to display device 9.When the driver notices this suggestion, he can determine to accept this suggestion and turn-off ignition switch 7, or may ignore this suggestion owing to stop conditions may close to an end.
If the driver turn-offs ignition switch 7, this will reduce by engine electrical system and such as ventilating and the electric load of the battery that some other Vehicular systems of headlight cause so.The reduction of electric load will significantly reduce the charge loss rate in the battery.When making vehicle keep static reason to finish, the same driver is with ignition switch 7 ato units, to continue his/her stroke when beginning with route.
On the other hand, if the driver ignores this suggestion and allow ignition switch 7 remain on " opening " position, battery will continue to keep whole vehicle electrical power load so.If the state of charge of battery is reduced to below the threshold value, ECU 5 will be restarted motor 3 automatically so that battery is charged again, therefore keep when vehicle and burn more fuel when static and produce toxic emission.
Referring now to Fig. 2, the operating method of ECU 5 is described.This method is from the step 20 of common disconnection ignition switch, arrive step 22 then, when ignition switch 7 moves to " opening " position and and then moves to enable position with ignition switch 7 instantaneous, arrive step 24 again, motor 3 is activated in step 24.
Whether this method is from step 24 to step 26, in step 26, can operate ECU 5 and move by using from the signal of vehicle speed sensor (not shown) to determine motor vehicle 1.Move if determine motor vehicle 1, this method enter circulation up to such as definite vehicle 1 when static till, if determine that motor vehicle 1 are static, this method is to step 28, in step 28, ECU 5 startups are set to the timer of termination after three minutes.
This method enters step 30 then, in step 30, can operate ECU 5 once more to determine whether motor vehicle 1 are moving.Moving if determine motor vehicle 1, this method is at step 32 replacement timer and be back to step 26.If determine that motor vehicle are static, this method proceeds to step 34, in step 34, can operate ECU 5 to check whether timer stops.If timer does not also stop, this method is back to step 30.If timer stops, this method advances to step 36, in step 36, can operate ECU 5, with by providing an output to make display device show the suggestion close igniting to the driver to display device 9, and the caution at the driver is set.
This method in step 38, can be operated ECU 5 to determine whether Motor Vehicle 1 is moving from step 36 to step 38 once more.If it is static determining vehicle, this method enters circulation up to such as till definite vehicle 1 is again when mobile.Moving if determine motor vehicle 1, this method advances to step 40, in step 40, can operate ECU 5 to remove the caution at the driver by display device is cut off the power supply.From step 40, this method is at step 32 replacement timer and be back to step 26.
Whenever, this method will be back to step 20 if the driver closes igniting, if driver's information warning just is being presented on the display device, this caution will be eliminated.
Should be appreciated that, after the static scheduled time, close igniting by alerting drivers at vehicle, unnecessary automatic engine is restarted the motor loss that causes when also reducing owing to stationary vehicle with encouragement driver fuel saving, reduction toxic emission.
