Abstract
The utility model discloses a collision avoidance device based on a self-adaptive cruise system. The device comprises a test vehicle, a radar, a single chip microcomputer, the self-adaptive cruise system, a microprocessor, a hydraulic braking valve and a display screen are further arranged on the test vehicle, the self-adaptive cruise system and the radar are respectively connected with an input end of the single chip microcomputer, an output end of the single chip microcomputer is respectively connected with the microprocessor and the hydraulic braking valve, and an output end of the microprocessor is connected with the hydraulic braking valve and a display. Due to the fact that an advanced control strategy and advanced logic judgment are adopted, a collision avoidance system is more ideal in the control effect, the device is simple in structure, compact, convenient to test and strong in adaptability, not prone to be affected by the outside, and stability and reliability are greatly improved.
Description
Technical field
This practicality relates to a kind of automotive correlation prevention device, relates in particular to a kind of based on the collision avoidance device under the self-adaption cruise system.
Background technology
Along with the process of China's rapid economic development and urban construction is accelerated day by day, the quantity of automobile also constantly rises.Because lack vehicle actv. administrative mechanism comparatively, vast driver safety consciousness is not high in addition, unreasonable the travelling of vehicle and the energy dissipation and the traffic accident quantity that cause also constantly rise caused enormous economic loss and personal casualty thus.When automobile driver travels at express highway, for the labour intensity that reduces chaufeur has produced the automotive self-adaptive cruise system, but for the complicated condition of road surface of China, traditional cruising device can't be given full play to its effect, and the present invention has done new exploitation with regard to collision avoidance function in traditional system.Traditional method control policy, its intelligent degree is low, is subjected to ectocine big, and bigger security risk is arranged.
Summary of the invention
This practical purpose is, it is a kind of based on the collision avoidance device under the self-adaption cruise system to provide this practicality to disclose, this device comprises the examination laboratory vehicle, and radar, micro controller system, self-adaption cruise system, microprocessor, hydraulic brake valve, read-out also are installed onboard.Described self-adaption cruise system, radar link to each other with the input end of micro controller system respectively, and the mouth of micro controller system links to each other with hydraulic brake valve with microprocessor respectively, and the mouth of microprocessor links to each other with hydraulic brake valve.
This practicality also has following other technologies characteristics:
Described micro controller system is Freescale S12 model micro controller system.
Described radar is installed on front part of vehicle, and its model is MR7180-67000004.
Described microprocessor, its model are the cRIO-9074 in the NI CompactRIO series.
Described hydraulic brake valve, its model are XML6795J13C.
Described self-adaption cruise system, 2010 editions self-adaption cruise systems that its model provides for AFW Volkswagen.
The advantage that this is practical: make control simple more, accurate, and simple to operateization; This apparatus structure compactness, comformability is strong, is not subject to ectocine, and stability and reliability have had bigger lifting.
Description of drawings
Fig. 1 is this practical structural principle scheme drawing.
Below in conjunction with the drawings and specific embodiments this practicality is described in further detail.
The specific embodiment
With reference to Fig. 1, this practicality provides that a kind of this device comprises the examination laboratory vehicle based on the collision avoidance device under the self-adaption cruise system, and radar, micro controller system, self-adaption cruise system, microprocessor, hydraulic brake valve, read-out also are installed on laboratory vehicle.Described self-adaption cruise system, radar link to each other with the input end of micro controller system respectively, and the mouth of micro controller system links to each other with hydraulic brake valve with microprocessor respectively, and the mouth of microprocessor links to each other with hydraulic brake valve.Wherein radar is installed on the real-time collection vehicle of vehicle front and rear situation all around, and its signal wire (SW) is connected with the first input channel PM0 of micro controller system; Self-adaption cruise system is installed on car inside, and its signal wire (SW) links to each other with the second input channel PM1 of micro controller system, and the command signal of sending for transmission system arrives micro controller system; Receive signal by micro controller system, through processing calculate after, the first delivery channel PB0 by micro controller system make signal pass to microprocessor it is installed in the car operator's compartment, for the treatment of the signal decision-making of gathering with carry out; Telltale is installed in the car operator's compartment, is used for the action that the chaufeur after demonstration is handled need carry out, and is connected with the first delivery channel PB2 of microprocessor; The input of hydraulic brake valve is linked to each other by the micro controller system signal PB1 of first treatment and the post-processed signal PB3 of microprocessor.
Wherein micro controller system is Freescale S12 model micro controller system.
When chaufeur was brought into use self-adaption cruise system, default collision avoidance strategy started.At this moment information around the real-time collection vehicle of radar and the operation information of self-adaption cruise system are arranged, pass to micro controller system and do first treatment, do inner complex logic, control policy computing, location estimation, dangerous estimation etc. by microprocessor then, send action or real chaufeur need carry out on telltale operation at last the fluid control valve, thereby being used for control finish collision avoidance.
Used electronic devices and components all are commercially available known product in the device of this practicality, and those skilled in the art can realize the connection of each electronic devices and components according to the application's technique effect.
This practicality is not limited to above-described embodiment, and those of ordinary skill in the art is under the instruction of this specification sheets, and increase or the replacement of the unsubstantiality that technical characterictic is carried out all should belong to this practical protection domain.
