Abstract
The utility model relates to a vehicle cruising with auxiliary safety function, which comprises a distance finding radar and an automobile cruising control device. A signal modem is electrically connected to the distance finding radar. A high-speed AD converter is electrically connected to the signal modem. A digit ratio filter is electrically connected to a micro-processor of the automobile cruising control device. During cruising time, the distance finding radar sends a monitored distance signal of the distance between the automobile and a former one to a control module via the signal modem, the high-speed AD converter and the digit ratio filter. The control module compares the monitored distance signal with a predetermined parameter in real-time. If the monitored distance is less than a predetermined alarm distance according to a certain vehicle speed, the control module will send a triggering signal to corresponding outputs of the vehicle and an actuator of the vehicle will quit from the cruising state and reduce the speed. Meantime, the actuator sends a slowdown and brake signal to the rear vehicle. The utility model is able to effectively prevent the rear-end collision and guarantee traffic safety.
Description
Technical field:
The utility model relates to automotive field, relates in particular to the control electronics of automobilism, the particularly auto-cruising control device of automobile, and concrete is a kind of Cruise Control device with auxiliary security function.
Background technology:
At present, intermediate car all is equipped with the auto-cruising control device.The Vehicle Speed signal that the auto-cruising control device is gathered by vehicle speed sensor is manually set toy vehicle velocity value by keyswitch.Vehicle speed sensor and keyswitch all are connected to a control module, control module compares the rate signal of collection and the toy vehicle velocity value of driver's setting, when the variation of vehicle of cruising owing to windage, road resistance, when the speed of a motor vehicle is lower than setting value, control module will be sent the instruction that strengthens engine throttle opening, strengthen engine throttle opening by the topworks that links to each other with control module, otherwise when the speed of a motor vehicle is higher than setting value, reduce engine throttle opening.So, make the vehicle that cruises keep the travel speed of setting.
But, auto-cruising control device of the prior art, the roadblock and the too small situation of spacing that occur in can't perception vehicle ' process.Must observe obstacle and the too small situation of spacing in person by the driver, and artificially withdraw from cruise function, perhaps step on brake pedal and withdraw from cruising condition by keyswitch control.Therefore the driver is not when long-distance running fatigue, energy are concentrated or the speed of a motor vehicle and spacing got the wrong sow by the ear, cruising condition can not be withdrawed from time, the traffic hazard of vehicle rear-end collision might take place, so there is certain potential safety hazard in use in existing auto-cruising control device.
Summary of the invention:
The purpose of this utility model provides a kind of Cruise Control device with auxiliary security function, and described this Cruise Control device with auxiliary security function will solve the roadblock that Cruise Control System in the prior art occurs in can't perception vehicle ' process and the technical matters of the too small situation of spacing.
This Cruise Control device with auxiliary security function of the present utility model is made of range radar and auto-cruising control device, described auto-cruising control device is by control module, vehicle speed sensor, keyswitch and topworks constitute, described vehicle speed sensor, keyswitch is connected with control module respectively with topworks, control module is made of microprocessor, wherein, described range radar is connected with signal modem, described signal modem is connected with high-speed AD converter, described high-speed AD converter is connected with the digital ratio wave filter, described digital ratio wave filter is connected with described microprocessor, described microprocessor is connected with vehicle signal input interface and vehicle signal output interface, and described microprocessor is connected with and shows and the remote alarm interface module.
Further, described microprocessor is a single-chip microcomputer.
Further, described microprocessor is connected with data storage and administration module.
Further, described microprocessor is externally connected to watchdog circuit.
Further, described range radar is arranged on the front portion of vehicle, and described auto-cruising control device is arranged on the interior of body of vehicle.
Concrete, range radar described in the utility model, auto-cruising control device and signal modem, high-speed AD converter and digital ratio wave filter all adopt technical scheme of the prior art, about range radar, auto-cruising control device and signal modem, high-speed AD converter and digital ratio wave filter technical scheme in the prior art, those skilled in the art all understands, so do not repeat them here.
Principle of work of the present utility model is: during vehicle cruise, be installed in the range radar of front part of vehicle that monitor with distance signal front truck be high-frequency carrier signal, signal modem converts high-frequency carrier signal to voltage signal and sends into high speed analog-digital conversion (D/A) converter, under the effect of analog to digital converter, analog quantity is converted to digital quantity, detect threshold values by the digital ratio wave filter again, the threshold values signal is delivered to control module (single-chip microcomputer) in real time.The warning distance parameter of the different cruise speed correspondences of vehicle, in advance in the embedded system control program of programming back, be stored in data storage and the administration module, control module contrasts the parameter set in the spacing signal of input and the program in real time, and the real-time status parameter of automobilism is provided by parameter input module.When the spacing signal less than the warning of setting speed of a motor vehicle correspondence apart from the time, control module is exported trigger pip simultaneously to the relevant output interface of automobile (braking, reduce-speed sign), is finished by topworks and withdraws from cruising condition and deceleration.Simultaneously, control module is to demonstration, remote alarm interface module and output trigger pip, and rearward vehicle sends and slows down and brake signal, reminds the back car to prevent to knock into the back.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model has added when cruising and has withdrawed from cruise function automatically and send sound and light alarm less than the warning spacing on the basis of existing automatic navigation of vehicle function, just sends brake signal simultaneously and remind the back car when vehicle deceleration.The utility model can prevent effectively that rear-end collision from taking place, guarantee driving safety, and the safety protection function of raising cruise system has good social benefit.
