Abstract
The utility model provides a gear identification system capable of preventing misoperation on an electromobile. The gear identification system comprises a gear shifting device, a gear signal identification device, an MCU (microprogrammed control unit), a drive motor and a reducer, wherein the gear shifting device is connected with the gear signal identification device; the gear signal identification device is connected with the MCU through a CAN (controller area network) bus, and the MCU is connected with the drive motor; and the drive motor is connected with the reducer. According to the utility model, if a driver has misoperation in a careless manner in an electromobile running process, the electromobile still moves towards the planned direction of the driver, and thus the electromobile is prevented from slowing down abruptly to cause an accident.
Description
[technical field]
The utility model relates to a kind of electric vehicle engineering field, relates in particular to a kind of gear identification system that prevents misoperation at electric vehicle.
[background technique]
Tradition is identified the gear operating lever position of vehicle, the general automatic transmission control systems that adopt more, and control system is finished direction of travel and the self-shifting control of vehicle according to the sensor signal of gear position operation bar position by actuator.Existing electric vehicle gear is not to adopt the mechanical type shifting pattern, but controls by entire car controller.The gear recognition device of existing electric vehicle and method are only considered the at present residing gear of switching gearshift of identification, and this gear signal is exported to vehicle, and vehicle is advanced according to this gear signal.If reckon without misoperation (as: gear directly is suspended to from forward gears and retreats shelves or be directly hung to forward gears from retreating shelves) occur in the electric motor car running process, under this situation, if the driver does not recognize the variation of gear, continuing steps on the gas deeply then may cause anxious deceleration of vehicle and the generation disaster.
A kind of " safety starting control method for vehicle " disclosed in the prior art, publication number is: CN1952383, open day be: the Chinese patent of 2007.04.25, its major character point is: comprise the following steps: (1) sampling neutral switch signal, brake switch signal, clutch position switching signal; (2) signal that samples according to step (1) judge whether neutral gear and whether step on brake and clutch whether from the position; (3) if if the arbitrary result who judges in the step (2) is no, then return step (1); (4) if the result who judges in the step (2) is yes entirely, then allow ignition trigger.This invention is the controlling method of traditional automobile starting, because electric vehicle is not identical with vehicle structure with gasoline, so the method and be not suitable for electric vehicle.
After a kind of " electric motor vehicle gears with constant speed ratio recognition device and method " disclosed again, publication number is: CN101907167A, open day be: the Chinese patent of 2010.12.08, its major character point is to comprise: detection unit, it detects current range state, and output is corresponding to the signal of current range state; Coding unit is used for described signal is encoded, to obtain new gear value; The first comparing unit is used for described new gear value and predetermined fault gear value are compared; And determining unit, it is defined as neutral gear in the situation that described new gear value equals described fault gear value with described current gear, and cuts off the power output of MCU.This invention is by judging that the driving switch output signal is in the some or all of invalid situation, and a kind of measure of taking is not to be the problem that misoperation brings, and the gear position operation when driving or stop does not carry out Division identification for occupant or driver.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of gear identification system that prevents misoperation at electric vehicle, can prevent that the driver from not recognizing the variation of gear, and continues deeply to step on the gas to cause the generation of car accident.
The utility model is achieved in that a kind of gear identification system that prevents misoperation at electric vehicle, it is characterized in that: comprise gear switching device, gear signal recognition device, MCU, drive motor and retarder; Described gear switching device is connected with described gear signal recognition device, and described gear signal recognition device is connected with described MCU by the CAN bus, and described MCU is connected with described drive motor; Described drive motor is connected with described retarder.
Further, described gear signal recognition device is entire car controller VCU.
Further, described gear identification system also comprises electrokinetic cell, described electrokinetic cell by the CAN bus respectively with described MCU be connected the gear signal recognition device and be connected.
The utility model has the advantage of: the utility model is to belong to which kind of gear by the gear signal that gear signal recognition device identification gear switching device sends, and whether the speed of judging vehicle is 0, if 0, the gear that then judges comes into force, if be not 0, judge that then this gear is neutral gear, be, then this neutral gear gear comes into force, no, then gear does not come into force, and MCU carries out corresponding steering operation according to the gear control drive motor that comes into force, if the gear that does not come into force, then motor keeps original steering operation.The utility model can be in the Vehicle Driving Cycle process, if misoperation occurs the driver accidentally, then vehicle still can advance towards the driver intention direction, prevents suddenly anxious deceleration of vehicle, causes burst accident; And the utility model carries out Division identification for the gear position operation of driver when driving or stop, and has more effectively prevented the generation of traffic accident.
[description of drawings]
Fig. 1 is structural representation of the present utility model.
[embodiment]
See also shown in Figure 1ly, a kind of gear identification system that prevents misoperation at electric vehicle of the present utility model comprises gear switching device 1, gear signal recognition device 2, MCU, drive motor 3 and retarder 4; Described gear switching device 1 is connected with described gear signal recognition device 2, and described gear signal recognition device 2 is connected with described MCU by the CAN bus, and described MCU is connected with described drive motor 3; Described drive motor 3 is connected with described retarder 4, and this retarder 4 can carry out decelerating effect to automotive wheel.
In the present embodiment, described gear signal recognition device is entire car controller VCU.Wherein, described gear identification system also comprises electrokinetic cell 5, described electrokinetic cell 5 by the CAN bus respectively with described MCU be connected gear signal recognition device 2 and be connected, this electrokinetic cell 5 provides power supply for the gear identification system.
Working principle of the present utility model is:
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
