Detailed description of the invention
A kind of safe distance between vehicles warning system based on road environment as shown in Figure 1, including controller module, spacing detection module, Bus-Speed Monitoring module, control panel, report to the police and drive module, voice alarm module and braking lamp control module, controller module is provided with an A/D interface, 2nd A/D interface, USB interface, first serial, second serial and alarm signal output interface, the outfan of spacing detection module connects a described A/D interface, the outfan of Bus-Speed Monitoring module connects the 2nd A/D interface, described USB interface is connected with the USB communication interface of vehicle-mounted ECU, the communication ends of control panel is connected with described first serial；
Report to the police and drive module to be provided with data communication end, alarm signal input, the first alarm signal output ends and the second alarm signal output ends, described data communication end connects described second serial, described alarm signal input connects described alarm signal output interface, described first alarm signal output ends connects the input of voice alarm module, and described second alarm signal output ends connects the input of braking lamp control module.
Described control panel is provided with LCD display, ordinary road button, rainwater road button, eisbahn button, snow road button and determines button as shown in Figure 2.
During work, spacing detection module and Bus-Speed Monitoring module are by actual spacing and speed data collection and send controller module to, controller module processes in real time, controller module reads initial speed of braking information by USB interface to vehicle-mounted ECU, driver selects traffic information by control panel, traffic information is sent to controller module by control panel, the relation of initial velocity and coefficient of road adhesion when controller module calculates theoretical braking distance with braking by below equation:
S=S1+S2, wherein,
S theory α coefficient distance, unit is rice；
S1Car braking distance, unit is rice；
v0For actual vehicle speed, unit is meter per second, and μ is coefficient of road adhesion, and g is acceleration of gravity
S2--in time of driver's reaction, brakes response time and braking system acts time, the distance that vehicle travels, unit is rice；
v0t1+v0t2=1.1v0
v0Ibid, t1For time of driver's reaction, t2For reaction time of braking device with braking system acts time sum for ensure safety to greatest extent, t1Take 0.8s, t2Take 0.3s；
This utility model is supplied to the coefficient of road adhesion of the different road conditions that driver selects: Ordinary Rd: μ takes 0.7；Rainwater road: μ takes 0.4；Snow road: μ takes 0.3；Eisbahn: μ takes 0.1；
Controller module calculates theoretical braking distance according to the coefficient of road adhesion of the different road conditions that above formula and driver select, and will contrast with theoretical braking distance and actual spacing, when actually detected value is less than theoretical value, controller module drives module to send alarm command by alarm signal output interface to reporting to the police, report to the police and drive module to send alarm command by the first alarm signal output ends to voice alarm module, voice alarm module sends audio alert, module is driven to send alarm command by the second alarm signal output ends to braking lamp control module with alarm, braking lamp control module controls Brake lamp and lights, rear car driver point out, shorten the rear car operator brake response time.
Report to the police and drive module to ask for speed information in real time to controller module by data communication end, when actual vehicle speed is lower than 20km/h, affect driver's emotion for avoiding alarm device frequently to report to the police, report to the police and drive module not send alarm command to braking lamp control module and voice alarm module.
