Description

Motor vehicles

Technical field

The present invention relates to a kind of motor vehicles with explosive motor, particularly relate to one have in order to Save fuel and reduce the motor vehicles of the system that waste gas discharges.

Background technology

When the vehicle is still, engine idle produces unnecessary fuel consumption, and is to avoid two Carbonoxide and the source of other waste gas discharge.It practice, now, in some cases, when vehicle is quiet Allowing engine long time idling time only is in violation of rules and regulations.

It is known that, it is provided that (have an opportunity so when determining in order to be automatically stopped and to start explosive motor When doing) vehicle control system, now many manufacturers introduce the vehicle with this system.So And, some dynamical systems combination (powertrain combinations) are more difficult to realize automatically start to walk- Shutdown system and cost are high.Demand such as automatic transmission, to variator transient response Requiring that hydraulic pump keeps operating, for large-scale diesel engine, the high inertia of diesel engine requires more powerful System guarantees quickly to respond.

For equipped with automatic stopping-starting system, engine stop-state can only continue by vehicle electrical The finite time that the charged state in pond determines.When it is shut off, alternating current generator no longer produces dynamic Power, and the whole electrical load of vehicle (includes ventilation, illumination, communication and entertainment systems (generally In the range of tens of amperes)) must be maintained by Vehicular battery.For guaranteeing battery has enough electric charges To ensure quickly to restart electromotor, electric charge or voltage threshold state and be typically defined to, less than this electric charge or In the case of voltage threshold, electromotor is restarted automatically or driver restarts electromotor to start battery weight New charging.

In the vehicle being not equipped with automatic stopping-starting, only because electromotor is not turned off or by In sound and/or the vibration of electromotor, when driver can be appreciated that stationary vehicle, electromotor is in operating.As Really vehicle stops in traffic or dwell time extends for other reasons, generally for driver, If vehicle seems to want static a period of time after a few minutes, for saving fuel, driver closes and sends out Motivation.But, inventor recognizes that driver forgets to close electromotor sometimes.

In the vehicle equipped with automatic stopping-starting, electromotor is often stopping shape when the vehicle is still State, the imperceptible any engine sound of driver or vibration.Not all driver can stand I.e. recognize: engine stop-state can not be maintained indefinitely.If vehicle dwell time extends, Function is then started to keep halted state (under the control of automatic stopping-starting control system), and Exceed driver and close the time of the electromotor in the vehicle not having automatic stopping-starting system.Thus want Ask Vehicular battery to continue to whole vehicle load, and electromotor must be restarted so that battery to be filled again Electricity, therefore when vehicle keep static time burn more multi fuel and produce waste gas discharge.Therefore, automatically stop Car-starting has maximum benefit for persistent period relatively short parking.Inventor has recognized Arriving, for the vehicle equipped with automatic stopping-starting, long-term parking is the most right Fuel consumption and waste gas discharge have negative net effect.

Summary of the invention

For one or more problems present in correlation technique, it is an object of the invention to provide one Having the motor vehicles of explosive motor, these motor vehicles can stop and driver for a long time at vehicle Driver is reminded to close igniter in the case of being not turned off electromotor.

Accompanying drawing explanation

With way of example referring to the drawings, the present invention is described, in accompanying drawing now:

Fig. 1 is the block diagram of the motor vehicles according to the present invention；And

Fig. 2 shows the side of the driver in order to warn motor vehicles shown in Fig. 1 according to the present invention The flow chart of method.

Detailed description of the invention

See Fig. 1, it is shown that there is the explosive motor (or internal combustion engine) 3 that controlled by control system Motor vehicles 1, this control system includes the automatically controlled list receiving input from key-operated ignition switch 7 Unit (ECU) 5.Ignition switch 7 is in order to control the overall operation of electromotor 3.That is, ignition switch is worked as 7 when first " closedown " position, and electromotor 3 can not operate, when ignition switch 7 is second " opening " During position, electromotor 3 can operate.Ignition switch 7 can also include manually booting electromotor 3rd instantaneous position of 3.It should be understood that other dresses of such as button, rocking bar or other type of switch Putting, can be provided for providing these functions, the present invention is not limited to use ignition switch.

ECU 5 provides output to the indicator of driver, and this indicator includes showing on Vehicular instrument panel Show device 9.Should be appreciated that, it is possible to use any type of display, be such as only used for following purpose Special warning lamp and/or as the acoustical generator of a part for entertainment systems in vehicle or be only used for following The special acoustical generator of purpose or touch screen, the present invention is not limited to use display 9.

For not possessing the conventional truck of parking-starting function, ECU 5 monitors holding of stationary vehicle The continuous time.It is not turned off electromotor or due to the sound of electromotor and/or shake although by driver Dynamic, when he/her can appreciate that stationary vehicle, electromotor is in operating, but if vehicle stops for a long time, Driver still may forget to close electromotor.In this case, if vehicle ignition switch 7 exists Being static during second " opening " position and keep the scheduled time, such as 3 minutes, then ECU is to aobvious Show that device 9 provides an output to show the suggestion that cut out igniting to driver.When driver notices During this suggestion, he/her may decide that it is to accept suggestion and turn off ignition switch 7, or is likely to be due to i.e. To again start and ignore this suggestion.

If driver turns off ignition switch 7, electromotor will stop, thus save fuel, reduce and give up Gas discharges and reduces the engine wear caused due to engine idle unnecessary during stationary vehicle.

At the end of making vehicle keep static reason, when starting with route as driver open with igniting Close 7 startup electromotors, to continue his/her stroke.

On some vehicles, ECU 5 can include parking-starting function, this parking-starting function in order to It is automatically stopped when determining and have an opportunity to do so and starts explosive motor 3, to save fuel and to reduce useless Gas discharges.In this case, occur when one or more predetermined engine stops and starting state Time, ECU 5 optionally stops when not having driver to get involved and starts electromotor 3.When During stationary vehicle, such as stop at traffic lights, occurred as soon as such halted state.Generally, This halted state continues several seconds to a few minutes until traffic light allow vehicle again to move, in Be when ECU 5 perceive ECU 5 when driver gets out actuating vehicle again will automatically restart send out Motivation 3.

But, halted state may last much longer in some cases, and such as vehicle is executed at road The Parking situation caused in the case of stopping at work or due to the accident in road ahead.In these feelings Under shape, ECU 5 will make electromotor 3 keep halted state, and Vehicular battery will continue to whole Vehicle electrical power loads, until such as driver when getting out again start vehicle or occurs startup to start Till during another situation of machine.But, ECU 5 monitors the persistent period of stationary vehicle, if continued Time exceedes the scheduled time (such as 3 minutes), and ECU 5 provides output to promote to show to display 9 Show that device shows the suggestion that cut out igniter to driver.When driver notices this suggestion, he/ She may decide that and accepts this suggestion and turn off ignition switch 7, or being likely to be due to stop conditions may be End is ignored this suggestion.

If driver turns off ignition switch 7, then this will reduce by engine electrical system and all Electric load such as the battery that some other Vehicular systems ventilated with headlight cause.The fall of electric load The low charge loss rate that will significantly reduce in battery.At the end of making vehicle keep static reason, with When route starts, the same driver starts electromotor by ignition switch 7, to continue his/her stroke.

On the other hand, if driver ignores this suggestion and allows ignition switch 7 be maintained at " opening " Position, then battery will continue to the load of whole vehicle electrical power.If the state of charge of battery reduces Below threshold value, ECU 5, by automatically restarting electromotor 3 to recharge battery, therefore works as car Maintain static time burn more fuel and produce waste gas discharge.

Referring now to Fig. 2, the operational approach of ECU 5 is described.The method is from common disconnection ignition switch Step 20 start, then arrive step 22, when ignition switch 7 moves to " opening " position tight When then moving to start position with the instantaneous movement of ignition switch 7, then to step 24, in step In 24, electromotor 3 is activated.

The method is from step 24 to step 26, and in step 26, operable ECU 5 is motor-driven to determine Whether vehicle 1 is being moved from the signal of vehicle speed sensor (not shown) by use.If really Determining motor vehicles 1 to move, the method enters circulation until during such as to determine that vehicle 1 is static, If it is determined that motor vehicles 1 are static, the method to step 28, in a step 28, ECU 5 opens Move the timer terminated after being set to three minutes.

Then the method enters step 30, in step 30, can again operate ECU 5 to determine machine Whether motor-car 1 is moving.If it is determined that motor vehicles 1 are moving, the method resets in step 32 Timer and be back to step 26.If it is determined that motor vehicles are static, the method proceeds to step Rapid 34, in step 34, operable ECU 5 is to check whether timer terminates.If timer The most not terminating, the method is back to step 30.If timer has terminated, the method proceeds to Step 36, in step 36, operable ECU 5, with by providing an output to make to display 9 Display shows the suggestion that close igniting to driver, and arranges the warning for driver.

The method is from step 36 to step 38, in step 38, can again operate ECU 5 to determine Whether motor vehicles 1 is moving.If it is determined that vehicle is static, the method enters circulation until such as Till determining that vehicle 1 is again when mobile.If it is determined that motor vehicles 1 are moving, the method proceeds to Step 40, in step 40, operable ECU 5 is with by removing for driving display power-off The warning of the person of sailing.From the beginning of step 40, the method resets timer in step 32 and is back to step Rapid 26.

Whenever, to light a fire if driver closes, the method will be back to step 20, if driven Member's information warning is just showing over the display, and this warning will be eliminated.

It should be understood that after the vehicle the most static scheduled time, close igniting by alerting drivers, with Driver is encouraged to save fuel, fall low exhaust gas emission and reduce due to unnecessary automatic during stationary vehicle Engine restarting and the engine wear that causes.
