Abstract
The utility model discloses a battery electric vehicle tipping over detecting and alarming device based on multi-information fusion, which comprises a battery electric vehicle and is characterized in that a gyroscope is mounted below a driver seat of the battery electric vehicle and is connected with a tipping over processor by a data line; a vehicle front wheel steering angle measuring device is mounted on a steering driving system of the vehicle and is connected with the tipping over processor by a data line; and real-time vehicle speed on an instrument panel is inputted into the tipping over processor. The tipping over processor is connected with a control and alarm device and can be an ECU (electronic control unit). The battery electric vehicle tipping over detecting and alarming device based on multi-information fusion can effectively judge the tipping over risk of the vehicle in real time, promotes a driver when the risk is larger and can perform braking and steering assisting control.
Description
Technical field
The utility model relates to the pure electric automobile vehicular field, relates in particular to a kind of pure electric automobile rollover based on many information fusion and detects and warning device.
Technical background
In the last few years, worldwide, automobile pollution increased sharply, and road traffic accident takes place again and again, caused a large amount of personal casualty and economic loss.Statistics shows that the rollover accident accounts for more than 20% in the car accedent that European and North America cause casualties.Cause the reason of vehicle rollover to have two: one is because the lateral impact of road barrier thing; Another is that transverse acceleration is excessive when moving owing to curve passing through, and wherein second is the major cause that causes rollover.Transverse acceleration is not only relevant with vehicle suspension, tire characteristics, and is also closely related with the speed of a motor vehicle, front wheel angle.Therefore, research and development one cover real-time collecting vehicle status data, and the rollover system of reporting to the police when rollover will take place is significant.
Summary of the invention
The purpose of this utility model is to provide the vehicle rollover that a kind of real-time is good, the warning accuracy rate is high to detect and warning device.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of pure electric automobile rollover detects and warning device, comprises pure electric automobile, it is characterized in that, below pure electric automobile vehicle driver seat gyroscope is installed, and gyroscope connects the rollover treater by data line; At the Vehicular turn transmission system vehicle front corner measuring apparatus is installed, this device is connected with the rollover treater by data line; Real-time speed of a motor vehicle input rollover treater on the gauge panel.Be connected with control and warning device on the rollover treater.
Described control and warning device are bearing circle electromagnetic shaker, brake pedal cylinder, steering booster.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is principle of work diagram of circuit of the present utility model;
The specific embodiment
As shown in Figure 1, a kind of pure electric automobile rollover detects and warning device, comprises pure electric automobile, below pure electric automobile vehicle driver seat gyroscope is installed.Gyroscope is that a kind of responsive housing relative inertness of moment of momentum space of high speed rotary body that utilizes is around the angular motion detecting device of one or two axle that is orthogonal to the axis of rotation.According to various gyrostatic characteristics and economy, can select the fiber optic gyro that the life-span is long, simple in structure, cost is low.Gyroscope is input to real-time measured vehicle lateral angle speed data in the rollover treater, obtains the vehicle lateral acceleration value after the conversion.
In order to guarantee the accuracy of rollover alarming, need measure current vehicle speed and vehicle front corner, take off data is turned on one's side after the risk analysis, as the decision-making assistant information of treater warning behavior.
The measurement of the speed of a motor vehicle is obtained by the speed information on the meter panel of motor vehicle, can reduce the modification to vehicle structure like this, cost-cutting.The speed of a motor vehicle numerical value that shows on the existing vehicle speedometer dial plate on the basis of considering traffic safety, shows that the speed of a motor vehicle is bigger than normal, and soon actual vehicle speed multiply by safety factor and shown.Therefore, in the rollover risk analysis, by speed of a motor vehicle coefficient of correction, the speed of a motor vehicle that shows on the gauge panel is reduced to the actual vehicle speed of vehicle, is conducive to precision of analysis.
The measurement of vehicle front corner is obtained by the vehicle front corner measuring apparatus.The vehicle front corner measuring apparatus is made up of sensor mechanical connecting device and signal output apparatus two parts.The sensor mechanical connecting device is installed on the motor turning transmission system, and connects the rollover treater by output circuit.
The rollover treater by following principle, is judged the rollover risk according to the take off data of gyrostatic instantaneous angular velocity, the speed of a motor vehicle and front wheel angle:
The first, instantaneous angular velocity is more big, and the trend that vehicle departs from original axis of travel is more big, and the rollover risk is more big;
The second, the speed of a motor vehicle is more big, and the anti-roll stiffness of vehicle suspension is more little, and the rollover risk is more big;
The 3rd, front wheel angle is more big, and the anti-roll stiffness of suspension is more little, and the rollover risk is more big.
More than three principles, set up the fuzzy control function respectively, based on first principle, second, third principle is auxiliary to be revised.By the ambiguity function diagram of curves of three principles of match, final definite rollover risk size.
The rollover risk hour is not reported to the police and the emergency control action; When the rollover risk is big:
The first, the vibrations of bearing circle electromagnetic shaker remind chaufeur to notice that rollover is dangerous;
The second, brake pedal carries out the early warning action, reduces invalid stopping distance;
The 3rd, reduce steering booster assisted diversion effect, force chaufeur by adjusting bearing circle, reduce front wheel angle.
Above-mentioned rollover treater can be electronic control unit (ECU).
