The principle of the vehicle alarming system of paddling of the utility model embodiment is as follows:
First, the sensor of paddling detects immersion information, and short alarm sound once.Now, open the level sensor of headlight adaptive adjustment module 3 (AFS), calculate angle information.Body control module 2 (BCM), according to the current vehicle speed and the angle information that collect, according to (5) formula, calculates to send and reports to the police and braking information.If t=0, output braking request, sends out braking information to ABS, and ABS carries out braking; T≤0.8S is long to report to the police; The quick short warning of 0.8 < t≤2S; Report to the police in 2 < t≤5S intervals.
Further, in the present embodiment, described in the sensor of paddling be preferably photoelectric liquid level sensor.
The sensor of paddling can adopt photoelectric liquid level sensor, and photoelectric liquid level sensor is the Novel connecting touch point liquid-level measuring-controlling apparatus that utilizes light to develop two kinds of extended media generation reflected refraction principles.It has simple in structure, and positioning precision is high; There is no mechanical part, do not need debugging; Highly sensitive and withstanding corrosion; Little power consumption; Plurality of advantages such as volume is little and be subject to the accreditation gradually in market, specific as follows:
1, only whether to contact liquid level relevant with photoelectric probe in the output of liquid level, with other characteristic of medium, as cache oblivious such as temperature, pressure, density, electricity, so that photoelectric liquid level sensor detects is accurate, repeatable accuracy is high; Fast response time, tank level control is very accurate, and does not need adjustment, just can directly install and use.
2, photoelectric liquid level sensor probe size is relatively small and exquisite, can be installed separately and in small space, be applicable to using in special tank body or container.Multiple photoelectric probe can also be installed in addition on a measurement body to be made multiple spot level sensor, becomes control device.
3, all components and parts of sensor internal have carried out the processing of resin encapsulation, and sensor internal is without any mechanical movable part, and therefore photoelectric liquid level sensor reliability is high, the life-span long, non-maintaining.
Whether 4, use photoelectric liquid level sensor to provide and soak, the degree of depth X1 information that level sensor provides, by fordable depth X and X1 relatively and corrected and obtain reasonable numerical value if offering Body control module 2 (BCM) as authorization information.Rectification mode provides information to be as the criterion with X, if but X < X1, X=X1.Rectification can ensure that data are accurate mutually.
In the technical scheme of the present embodiment, this paddles vehicle alarming system in the time that vehicle soaks, obtain immersion information by the sensor of paddling, and give the alarm, meanwhile, Body control module obtains current driving states, go out to brake the moment according to described current driving state computation, and send and report to the police and braking information, while having realized road ponding vehicle and alarm and braking, avoid due to the vehicle lives and properties infringement causing of soaking, and, take full advantage of further existing electronic apparatus system on car, realize and reporting to the police and braking function, also saved and become to produce cost.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
