Description
Technical field
The utility model relates to automobile controller, the control setup of the electromotion rearview mirror of car that especially uses when reversing automobile.
Background technology
At present, the outside rear-view mirror of automobile is installed in the both sides of automobile, and when automobile normal running, outside rear-view mirror is towards the road at automobile rear, and chaufeur is observed back car and road conditions by outside rear-view mirror.But when reversing automobile, just there is blind area in outer visor, can not observe near the obstacle of rear wheel.Blind zone problem when solving reversing, during reversing chaufeur adopt manual regulation (by push button control back mirror motor) control outside rear-view mirror towards angle.It is repeatedly to adjust lens position that reversing is regulated, the right back mirror particularly, the back mirror angle when needing again again to recall to motoring condition after the reversing.As seen, reversing is regulated outside rear-view mirror and is extremely bothered, and therefore more chaufeurs are selected not adjust.Yet, if lens position is constant, there is the blind area in the visual field, driving like this is quite dangerous.
Therefore, in order to solve above-mentioned this problem, there is a kind of control setup of automobile rearview mirror memory to be used in the automobile.The control setup groundwork principle of this automobile rearview mirror memory is: when micro controller system collects the reverse signal, drive again the motor rotation of control driven rearview mirrors, the potential device of installing simultaneously again on the back mirror gathers the rotational angle signal of automobile rearview mirror to micro controller system, after reaching the angle numerical value that storage is set in memory device or the monolithic Bigpian internal memory storage district, stop the motor rotation of driven rearview mirrors, namely realized the back mirror angular adjustment control of reversing.When treating again the reverse blackout, the angle when micro controller system is controlled back mirror again again according to above-mentioned control process motor is adjusted back mirror reversion and sailed.The weak point that the control setup of this existing automobile rearview mirror memory exists is: 1. potential device is the acquisition elements that the contact is arranged, and has cliding friction, gathers not high, the life-span weak point of sensitivity of the rotational angle of back mirror by potential device; 2. can only detect the back mirror vertical angle and can not detect the back mirror level angle, be unfavorable for the multi-faceted adjustment of back mirror.3. the installation of potential device need to be integrated in the back mirror commutator assembly, needs to change the commutator assembly, safeguards that replacement cost is high.4. chaufeur not necessarily is applicable to all driver habits according to the vehicle backing backsight mirror angle of the angular adjustment of setting.
The utility model content
Therefore, the utility model is for the control setup above shortcomings part of existing automobile rearview mirror memory, and the control setup that proposes a kind of improved automobile rearview mirror memory solves.
The technical solution of the utility model is:
A kind of control setup of automobile rearview mirror memory comprises:
-micro controller system, the port of micro controller system are connected in reversing automobile signal port and chaufeur signal port, and the port of micro controller system also is connected on contact pointless obliquity sensor, nonvolatile memory and the motor control chip;
-contact pointless obliquity sensor, mouth are connected on the port of above-mentioned micro controller system, and the contact pointless obliquity sensor gathers vertical angle and the level angle of back mirror and exports transducing signal to micro controller system;
-nonvolatile memory, input/output terminal are connected on the port of above-mentioned micro controller system, and nonvolatile memory is stored vertical angle and the level angle data of back mirror, and are read and write by micro controller system;
-motor control chip, input end are connected on the port of above-mentioned micro controller system, and output port is connected in the motor of back mirror.
Further, described contact pointless obliquity sensor is mounted on the commutator of automobile rearview mirror or is fixed on the eyeglass of automobile rearview mirror.
Further, the model of described contact pointless obliquity sensor is SCA60C or SCA100T or SCA103T or SCA1020 or ADXL335 or ADXL345 or MMA7455 or MMA7260 or MMA7361 or MMA8452 etc.
Further, described nonvolatile memory is the storage location module that is integrated in the micro controller system.
Further, described nonvolatile memory is eeprom memory or FLASH memory device.
Further, described motor control chip is DC MOTOR CONTROL chip or step motor control chip.
Further, the port of described micro controller system carries out the photoelectricity isolation with being connected by the access optical coupler of reversing automobile signal port, chaufeur signal port and motor control chip.
The utility model adopts above-mentioned technical scheme, can replace by the contact pointless obliquity sensor mode of traditional potentiometer pick-off, has the higher and longer service life of sensitivity and can measure the advantage of vertical angle and level angle.Simultaneously, can realize angle acquisition because the contact pointless obliquity sensor only need to be installed on the commutator of automobile rearview mirror or be fixed on the eyeglass of automobile rearview mirror, therefore not having potential device is integrated in the deficiency that the commutator assembly replaces with in maintenance.At last, convenient in the use because also a plurality of chaufeur signals of tool are inputted angle and the rear-view mirror of car for back astern angle that can adjust according to different chaufeurs the automobile normal running back mirrors, meet a plurality of different driver habits.
