For being equipped with simultaneously-automobile of stop device and extended edition ACC system (band " start-stop " function), following problem may be there is in actual applications, such as when ACC system requirements automobile enters dead ship condition, rise-stop device can take measures with ACC system simultaneously, thus, combustion engine will be risen-and stop device closes, and only has when chaufeur provides action (such as the pedal operation) that restart, and combustion engine just allows to be activated.
Summary of the invention
Task of the present invention is, proposes a set of apparatus and method for controlling car combustion engine operational mode, to avoid because playing-conflicting and cause dysfunction, unexpected automobile sport mode in other words between stop device with ACC system.
This task is solved passing through according to the device and method with following feature.
Device for controlling car combustion engine operational mode involved in the present invention, there is a brake piping, at least one is for measuring the sensor of brake-pipe pressure, a set of for automatically close or open combustion engine rise-stop device, and a set of according to sensor obtain the self adaptation speed controller that car body environmental information regulates the speed of a motor vehicle.Wherein, self adaptation speed controller is equipped with a brake cylinder worked to brake piping.
The feature of said apparatus is, it rises-stop device and self adaptation speed controller combine as follows, that is, the automatic closedown of combustion engine or startup, by-stop device directly realizes based on the brake-pipe pressure measured by sensor.
The most basic theory of the present invention is, to being equipped with simultaneously-automobile of stop device and self adaptation speed of a motor vehicle control apparatus (be also referred to as ACC-system, and be provided with " rise-stopping " function), the combination between both will be realized by brake-pipe pressure.
-direct combination between stop device and ACC-system is realized with brake-pipe pressure, and do not realize by obtaining pedal position (in other words chaufeur provide pedal operation) in a traditional way, can avoid-stop device and ACC-system provide conflicting measure (in other words mode).
Especially, no matter whether ACC-system in running order, by brake-pipe pressure (may by the amount of ACC-systematic influence), as conclusive amount, all can have been ensured-stop device correctly, work to noncontradictory.
Therefore, done consideration to following situation, namely the change of brake-pipe pressure is caused by ACC-system, and that is, pedal operation that the change of brake-pipe pressure and chaufeur provide and so on has nothing to do.In this case, only there is the rising of response-stop device can not work in the mode expected to pedal operation, just do not occur because pedal operation is basic.In contrast, in scheme involved in the present invention, then still can ensure its correctly (ground of noncontradictory in other words) operation, because to playing-the brake-pipe pressure that plays a decisive role of stop device correlation function, be associated with the action of ACC-system (impact being subject to ACC-system in other words).
In other words, be no matter the parking of ACC-system triggers, still restart, can to have guaranteed-stop device is in conflict free state because the brake-pipe pressure be here associated with ACC-systemic-function by as-decisive factor of stop device.
According to design plan of the present invention, its another advantage is, on the automobile without ACC-system or ACC-system down, it also can be applied, and without the need to connecting the change done in essence to system.Due to brake-pipe pressure by as-deciding factor of stop device generation action, therefore, for the situation without ACC-system or ACC-system down, brake-pipe pressure is had to the rising of responsibility-stop device still can work exactly, because based on the relevance of brake-pipe pressure change with pedal operation, chaufeur by step on or discharge that brake pedal applies affect measure, still can accurately be performed.
According to certain form of implementation of the present invention, to rise-stop device designs as follows, automatically can complete closedown or the unlatching of combustion engine, and do not rely on the pedal operation that chaufeur provides.
According to certain form of implementation of the present invention, brake pedal and self adaptation speed controller are equipped with independent of the brake wheel cylinder both this.
According to certain form of implementation of the present invention, only have when the brake-pipe pressure value that sensor records exceedes threshold value that certain presets, rise-stop device just can close combustion engine automatically.In addition, the brake-pipe pressure value only recorded at sensor, lower than under the condition of certain predetermined threshold value, to rise-stop device just can open combustion engine automatically.
In addition, the invention still further relates to a set of method for controlling car combustion engine operational mode, under this methodology, automobile has a brake piping, at least one is for measuring the sensor of brake-pipe pressure, a set of for automatically close or open combustion engine rise-stop device, and a set of based on sensor obtain the self adaptation speed controller that car body environmental information regulates the speed of a motor vehicle.Wherein, self adaptation speed controller is equipped with a brake cylinder worked to brake piping.Here, the auto-stop of combustion engine or startup, by-stop device directly completes based on the brake-pipe pressure measured by sensor.
The design that the method is favourable and advantage, be associated with the existing structure of device involved in the present invention.
According to certain additional design, at automobile by ACC-system triggers after entering dead ship condition, chaufeur by the irrelevant action of certain and pedal operation (such as, by pressing certain special button), and in the conceived case, by responding the request that certain issues chaufeur in advance, be confirmed whether to allow-stop device automatically reopens combustion engine.Therefore, this can avoid equally by-conflict caused dysfunction (in other words between stop device with ACC-system, unexpected automotive operation mode), and this does not also have dependence to the coupled relation set up by brake piping between aforementioned-stop device and ACC-system.
According to further conception, therefore the present invention also relates to a set of device for controlling car combustion engine operation scheme.Here, automobile has:
-a set of for automatically close or open combustion engine rise-stop device; And
-a set of peripheral vehicle environmental information obtained based on sensor, realizes the self adaptation speed controller that the speed of a motor vehicle regulates,
-wherein, to rise-stop device designs as follows, i.e. the automatic shutdown of combustion engine or startup, the action (as pressing certain special button) had nothing to do by certain and pedal operation completes.
Other design form of the present invention, can know from associated description.
Subsequently, will by certain preferred embodiment, and with reference to relevant drawings, the present invention is further elaborated.Accompanying drawing is shown:
