Description

The urgent auxiliary braking system of a kind of heavy duty truck
Technical field
The utility model relates to a kind of urgent auxiliary braking system, especially relates to a kind of heavy duty truck and prevent the urgent auxiliary braking system of driver fault misstepping on accelerator.
Background technology
The development of domestic Truck Market rapidly, and the heavy duty truck important developing direction that is it.But along with the increase of heavy duty truck recoverable amount, the safety problem of bringing also more and more attracts much attention, especially the rear-end collision causing because of driver fault misstepping on accelerator, cause immeasurable property damage, life security to the mankind has produced serious threat, and brake system is one of important system of automobile active safety.Therefore prevent that for heavy duty truck development is a kind of the urgent auxiliary braking system of driver fault misstepping on accelerator is necessary.
Utility model content
The purpose of this utility model is: provide a kind of heavy duty truck urgent auxiliary braking system, and while realizing driver fault misstepping on accelerator, automobile autobrake.
For addressing the above problem, the utility model has adopted following technical proposals: a kind of heavy duty truck emergency brake system, comprises STM32 micro controller system, microwave radar sensor, Das Gaspedal acceleration pick-up, car speed sensor, electric control braking valve and annunciator.Described microwave radar sensor signal mouth is connected with STM32 one-chip machine port, Das Gaspedal acceleration transducer signals mouth is connected with STM32 one-chip machine port, car speed sensor signal output part is connected with STM32 one-chip machine port, electric control braking valve signal input end is connected with STM32 one-chip machine port, and annunciator signal output part is connected with STM32 one-chip machine port.
STM32 micro controller system receives after spacing signal, the throttle acceleration signal of Das Gaspedal acceleration pick-up output and the vehicle speed signal of car speed sensor output of microwave radar sensor output, received information is analyzed, and then judge whether mis-accelerator pressing of chaufeur, and send signal to electric control braking valve and annunciator.If mis-accelerator pressing, starts electric control braking valve and report to the police, heavy duty truck is realized autobrake.
That the urgent auxiliary braking system of the utility model has is easy for installation, response fast, the in the situation that of driver fault misstepping on accelerator, realize the feature of autobrake.
Brief description of the drawings
Fig. 1 is the framed structure schematic diagram of the utility model device.
1:STM32 micro controller system; 2: microwave radar sensor; 3: Das Gaspedal acceleration pick-up; 4: car speed sensor; 5: electric control braking valve; 6: annunciator.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further illustrated.
The present embodiment is the auxiliary braking system under a kind of heavy duty truck emergency state.As shown in Figure 1, this module comprises: STM32 micro controller system 1, microwave radar sensor 2, Das Gaspedal acceleration pick-up 3, car speed sensor 4, electric control braking valve 5 and annunciator 6.
Described microwave radar sensor signal mouth is connected with STM32 one-chip machine port, Das Gaspedal acceleration transducer signals mouth is connected with STM32 one-chip machine port, car speed sensor signal output part is connected with STM32 one-chip machine port, electric control braking valve signal input end is connected with STM32 one-chip machine port, and annunciator signal output part is connected with STM32 one-chip machine port.
STM32 micro controller system receives after spacing signal, the throttle acceleration signal of Das Gaspedal acceleration pick-up output and the vehicle speed signal of car speed sensor output of microwave radar sensor output, received information is analyzed, and then judge whether mis-accelerator pressing of chaufeur, and send signal to electric control braking valve and annunciator.If mis-accelerator pressing, starts electric control braking valve and report to the police, heavy duty truck is realized autobrake.
Described microwave radar sensor 2 signal output parts are connected with STM32 micro controller system 1 port, Das Gaspedal acceleration pick-up 3 signal output parts are connected with STM32 micro controller system 1 port, car speed sensor 4 signal output parts are connected with STM32 micro controller system 1 port, electric control braking valve 5 signal input parts are connected with STM32 micro controller system 1 port, and annunciator 6 signal output parts are connected with STM32 micro controller system 1 port.STM32 micro controller system 1 receives after the vehicle speed signal that spacing signal that microwave radar sensor 2 exports, throttle acceleration signal that Das Gaspedal acceleration pick-up 3 is exported and car speed sensor 4 export, received information is analyzed, and then judge whether mis-accelerator pressing of chaufeur, and send signal to electric control braking valve 5 and annunciator 6.If mis-accelerator pressing, starts electric control braking valve 5 and report to the police, heavy duty truck is realized autobrake.
