Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
See Fig. 1, upper as can be seen from figure, automobile parking braking safety prompting system of the present invention, this prompt system comprises detecting element, detecting element comprises to be located on each wheel for detecting the wheel speed sensors 1 of vehicle wheel rotation, be located on emergency brake system for detecting the braking during standstill contact switch 2 of whether parking, with brake pedal link for detecting the brake pedal contact switch 3 whether brake pedal jams on, for detecting the driving engine detector switch whether driving engine 4 works, all sensitive members connect signal acquisition process controller 5, signal acquisition process controller 5 Tip element taking alarm.
Described alarm unit comprises the combination instrument 6 of audible alarm unit and band alarm icon 7, and when warning, alarm icon 7 will be lit and glimmer.
Wheel speed sensors is responsible for collection vehicle speed, judges whether vehicle is in running state with this.Because common roadlice wheel is four, therefore four wheel speed sensors output signals are had, add engine operation whether detection signal, emergency brake system detection signal, brake pedal detection signal again, always have seven Signal transmissions to signal acquisition process controller, signal acquisition process controller then determines whether will send alarm according to the output situation of these seven signals by the judgment rule pre-set.
The detection ratio whether driving engine works is easier to, and throttle gate existing on vehicle, spraying nipple and light-up plug etc. can be detected as detector switch.
Because existing vehicle inherently has braking during standstill contact switch, brake pedal contact switch, when parking, parking indicator lamp in braking during standstill contact switch and instrument is connected, when braking, brake pedal contact switch and brake indicating lamp are connected, so the signal of braking during standstill contact switch, brake pedal contact switch directly can be gathered, to judge whether vehicle carries out braking during standstill and drag.Fig. 2 and Fig. 3 is existing motor vehicle braking system arrangement plan.
