Abstract
The utility model discloses an automobile hard braking warning system, which is characterized in that the signal output ends of an automobile braking signal device and an automobile speed signal device are connected with an electronic control unit (ECU); the signal output end of the ECU is connected with a switching circuit; and the switching circuit controls a warning device. When a vehicle makes a hard brake in meeting an unexpected event, the automatic warning system can warn surrounding pedestrians and vehicles to alert the danger earlier and automatically evade, and thereby, traffic accidents are reduced and the running safety of the vehicles is enhanced.
Description
Technical field
The utility model relates near a kind of automobile automatic warning of the vehicle caution when emergency brake.
Background technology
Vehicle runs into emergency situations in the process of moving when taking emergency brake, chaufeur may take the anxious direction etc. of beating to dodge measure simultaneously, vehicle there is no alerting automatic telling status when this emergency situations produced, vehicle on every side, pedestrian can't obtain caution in advance and make the measure of dodging accordingly, when surrounding vehicles, pedestrian more for a long time, when perhaps coming between vehicle and sudden stop, to have shelter, this unexpected brake turning avoidance will certainly threaten the safety of surrounding vehicles, pedestrian and Ben Che, has traffic hidden danger.
The utility model content
The technical problems to be solved in the utility model is to realize a kind ofly stopping when dodging in that vehicle is anxious, and vehicle can be warned the caution system that surrounding vehicles, pedestrian are dodged automatically.
To achieve these goals, the technical solution adopted in the utility model is: a kind of automobile urgent brake caution system, signal output part by automobile brake signal apparatus and vehicle speed signal device is connected with ECU (electronic control unit), the ECU signal output part connects switch circuit, described switch circuit control warning device.
Described ECU is can be in real time to vehicle speed signal, brake signal collection, and can judge the control chip whether automobile is in the anxious state of stopping.
Described warning device is the original accessory of automobile, comprising: head light, two flashing light and loudspeaker.
Described vehicle speed signal device is for obtaining the device of real-time vehicle speed signal, and its device is car speed sensor or CAN bus or wheel speed signal or average speed indicator.
Advantage of the present utility model is to run into emergency situations suddenly in a flash when vehicle, this automatic warning system can be warned pedestrian, vehicle on every side, make it more early be alerted to danger and also dodge automatically, reduced the generation of traffic accident, improved the safety performance of vehicle '.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model specification sheets and the mark among the figure are made brief description:
Fig. 1 is the system chart of automobile urgent brake caution system.
The specific embodiment
The system chart of automobile urgent brake caution system as shown in Figure 1 as can be known, this automobile urgent brake caution system, be connected with ECU1 by the brake signal apparatus 3 of automobile and the signal output part of vehicle speed signal device 2, the ECU1 signal output part connects switch circuit 4, switch circuit 4 control warning devices.
Brake signal apparatus 3 is for obtaining the signalling apparatus that brake pedal is depressed braking automobile, can from the original device of automobile, obtain this signal, the CAN bus of automobile for example, when chaufeur was made brake, this device This move signal that will brake passed to ECU1; Vehicle speed signal device 2 is for obtaining the device of real-time vehicle speed signal, and its device passes to ECU1 with real-time vehicle speed signal to analyze for car speed sensor or CAN bus or wheel speed signal or average speed indicator; Switch circuit 4 is the driving circuit of warning device, accept ECU1 order after, the control warning device is opened executive command; Warning device can utilize the original accessory of automobile, comprising: headlight 5, two flashing light 6 and loudspeaker 7, and all or part of unlatching of these devices can be played warning function; ECU1 is can be in real time to vehicle speed signal, brake signal collection, and can judge the control chip whether automobile is in the anxious state of stopping, and control chip can be 8 or 16 or 32 s' High Speed Microcontroller or a microprocessor.For example, the MC9S08XX/12XX of Freescale or ColdFire series, the XC800/XC16X/XC2000 of Infineon or TC17XX series, meaning method ST7/ST8/ST10/STM32 series, the 78K0/78K0R/RX series of auspicious Sa etc.
When said system was depressed at brake pedal, brake signal apparatus 3 sent brake signal and passes to ECU1 and picks up counting.ECU gathers the instantaneous speed of a motor vehicle by vehicle speed signal device 2, and the contrast speed of a motor vehicle is with respect to the rate of change of time, thereby judges whether to belong to the anxious state of stopping.When ratio reached threshold values, ECU1 judged that brake is emergency brake, at this moment the ECU1 output switch control signal.On-off signal starts warning device through switch circuit, promptly lights two flashing lights 6 respectively, and the head light 5 and the loudspeaker 7 of ringing allow to send a car in the opposite, the back is seen with car and car limit pedestrian or hear that signal produces and realize in surperise or dodge.
