Switching signal output circuit transmits a signal to analog input signal, and described analog input signal transmits a signal to
Single-chip microcomputer, described single-chip microcomputer transmit a signal to signal output apparatus, and described signal output apparatus transmits signal respectively
To electronics parking brake controlling switch and buzzer alarm.
Beneficial effect：
1. of the present utility model can install delivered vehicle additional, can not only avoid to automatic becoming because of human error
Fast case damages or car slipping.
2. the utility model can realize it is various need start parking brake in the case of, parking brake automatically starts, for drive
Person removes the step of pulling parking brake switch from, to provide facility.
3. the utility model can install additional to the vehicle for being not equipped with automatic parking function, due to sensor be former car
There is sensor, installation cost is low, can effectively avoid automatic gear-box internal gearing device from producing impact with engine gear, while can
Avoid triggering accident because driver forgets to start parking brake.
Brief description of the drawings：
Accompanying drawing 1 is signal flow schematic diagram of the present utility model.
Accompanying drawing 2 is logic chart of the present utility model.

When automatic gear-box is linked into P gears by driver, AT89C52 single-chip microcomputers receive fluid drive gear box and are located at P gears
Signal, now electronics parking brake controlling switch startup；
Stop working when gearbox is not linked into P gears by driver, AT89C52 single-chip microcomputers receive fluid drive gear box and do not existed
P gears signal, engine speed are zero-signal, speed is zero-signal, and now electronics parking brake starts, while buzzer alarm is sent certainly
Dynamic gearbox-gear is not linked into P gear buzzers；
When vehicle accident extinguishing, AT89C52 single-chip microcomputers receive fluid drive gear box and do not keep off signal, engine turn in P
Speed is not zero signal for zero-signal and speed, and now siren sends flame-out parking buzzer, after speed is zero, electronic hand
Stop and start；
When engine does not stop working, gearbox-gear is not when P is kept off, and driver gets off temporarily, and AT89C52 single-chip microcomputers receive
Fluid drive gear box does not keep off signal, engine speed in P and is not zero signal, operator seat car door opening signal, now electronic hand
Stop and start, while siren sends gear and is not linked into P gears and the not flame-out buzzer of engine.
Automatic gear-box driving switch in automatic gearbox of vehicles, for whether detecting gear positioned at P gears, and produce
Raw corresponding signal is transmitted to single-chip microcomputer；
Engine speed sensor in vehicle motor, for being with engine according to engine speed, generation
The no corresponding signal that stops working is transmitted to single-chip microcomputer；
Positioned at the vehicle speed sensor of in-car, for detecting speed, and to single-chip microcomputer input speed whether the signal for being zero；
