Abstract
The utility model discloses a system for rear-end collision avoidance warning and automatic control of an automobile and belongs to the technical field of automobile electronics. The system for rear-end collision avoidance warning and automatic control of the automobile disclosed by the utility model mainly consists of an ultrasonic wave transmission module, a data processing and speed limiting module and a delivery module, wherein the ultrasonic wave transmission module is divided into two parts, namely a transmitter and a receiver. The receiver is installed on the head part of a vehicle and used for receiving the instant speed and distance data of a front vehicle and recording the instant speed and distance data of the vehicle, then packaging the data and delivering the packaged data to the data processing and speed limiting module. The data processing and speed limiting module evaluates a theoretical total braking distance d by utilizing the speeds and space of the two vehicles, and compares the theoretical total braking distance d with an instant vehicle space D. If d is not greater than D, the vehicle is regarded as entering in a blocked area already, the data processing and speed limiting module sends a warning signal to a driver and starts a function of automatic speed reduction, so that the vehicle automatically reduces the speed until d is greater than D. During the time period, manual acceleration using an accelerator is invalid. The system for rear-end collision avoidance warning and automatic control of the automobile has the advantages of being simple in principle, lower in cost, obvious in acting effect, and the like.
Description
Technical field
The utility model relates to a kind of automobile anti-rear end collision caution and autonomous cruise speed system, and caution and the restricting vehicle moving velocity automatic speed-limiting system to prevent that rear-end collision from taking place specifically is provided automatically, belongs to technical field of automotive electronics.
Background technology
The rear-end collision accident accounts for more than 70% of all traffic accidents, and normal for causing the major reason of especially big traffic accident.What therefore reduce the rear-end collision accident is the necessary ways that effectively reduce traffic accident, reduce personal casualty and property damage.
Summary of the invention
The utility model is a kind ofly to be the basis with the ultrasound data transmission technology; Can according to vehicle be time interval and moving velocity provide automatically the caution and the restricting vehicle moving velocity; Make between the automobile to keep a safe distance, thereby prevent the safety system that rear-end collision takes place.
The utility model is realized through following technical scheme:
A kind of automobile anti-rear end collision caution and autonomous cruise speed system are made up of with speed limit module and delivery module ultrasonic transmission module, data handing.The ultrasonic transmission module is made up of projector and receptor two parts, and receptor is connected with the speed limit module with data handing respectively with delivery module; Data handing is connected with brake system of car with the speed limit module.
The projector of said ultrasonic transmission module is installed the pairing front truck afterbody of this automobile direction of relative movement, and receptor is installed in this headstock portion.Per car should be furnished with this automobile anti-rear end collision caution and autonomous cruise speed system of at least one the whole series.
Wherein the ultrasonic transmission module is divided projector and receptor two parts.Receptor is installed in the headstock part of vehicle, receives the instantaneous velocity and the range data of front truck and minute book car, sends the data packing to data handing and speed limit module thereafter.Data handing and speed limit module are by two vehicle speeds and spacing, according to formula: d=0.75v+0.0255v
2(d is reaction distance and stopping distance sum, and reaction distance is got default value.V is this vehicle speed, and preceding vehicle speed only is used to ask instant spacing) obtain the total distance of theoretical brake, see that whether d is less than instant spacing D.If d≤D thinks that then vehicle has got into block section, data handing and speed limit module are sent alarm signal to chaufeur, and start the automatic deceleration function, make this car automatic deceleration until d＞D, and in this time period, it is invalid that artificial use throttle quickens.
Advantages such as it is simple that caution of this automobile anti-rear end collision and autonomous cruise speed system have principle, and cost is lower, and action effect is obvious.
Description of drawings
Fig. 1, Fig. 2 be the scheme drawing of utility model for this reason.
The specific embodiment
The utility model is a kind ofly to be the basis with the ultrasound data transmission technology; Can according to vehicle be time interval and moving velocity provide automatically the caution and the restricting vehicle moving velocity; Make between the automobile to keep a safe distance, thereby prevent the safety system that rear-end collision takes place.
The utility model is realized through following technical scheme:
A kind of automobile anti-rear end collision caution and autonomous cruise speed system are made up of with speed limit module and delivery module ultrasonic transmission module, data handing.The ultrasonic transmission module is made up of projector and receptor two parts, and receptor is connected with the speed limit module with data handing respectively with delivery module; Data handing is connected with brake system of car with the speed limit module.
The projector of said ultrasonic transmission module is installed the pairing front truck afterbody of this automobile direction of relative movement, and receptor is installed in this headstock portion.
Per car should be furnished with this automobile anti-rear end collision caution and autonomous cruise speed system of at least one the whole series.
Wherein the ultrasonic transmission module is divided projector and receptor two parts.Receptor is installed in the headstock part of vehicle, receives the instantaneous velocity and the range data of front truck and minute book car, sends the data packing to data handing and speed limit module thereafter.Data handing and speed limit module are by two vehicle speeds and spacing, according to formula: d=0.75v+0.0255v
2(d is reaction distance and stopping distance sum, and reaction distance is got default value.V is this vehicle speed, and preceding vehicle speed only is used to ask instant spacing) obtain the total distance of theoretical brake (default formulae, concrete formula can because of road surface and the different different modes that use of weather conditions), see that d is whether less than spacing D immediately.If d≤D thinks that then vehicle has got into block section, data handing and speed limit module are sent alarm signal to chaufeur, and start the automatic deceleration function, make this car automatic deceleration until d＞D.In this time period, it is invalid that artificial use throttle quickens.
Advantages such as it is simple that caution of this automobile anti-rear end collision and autonomous cruise speed system have principle, and cost is lower, and action effect is obvious.
