Description
Technical field
The invention belongs to the electron controls technology field, relate to a kind of controller for delayed turn-off of brake light of electric car.
Background technology
Battery-driven car, when fast running, when running into turning or unforeseen circumstances, need to make battery-driven car slow down or stop with handle brake or footbrake.The battery-driven car majority is handle brake or footbrake, and the stoplight stop lamp of battery-driven car is lit simultaneously, and once unclamping, brake system resets immediately with handle brake or footbrake gang switch, and stoplight stop lamp extinguishes immediately.The job procedure that the electric vehicle brake lamp is such, be not easy to cause the attention of back vehicle, is easy to cause the vehicle immediately following thereafter to knock into the back.
Most of battery-driven cars do not have the stoplight stop lamp job procedure that the camera motor-car is the same on the market, a potential safety hazard when this has just formed fast running, so on battery-driven car, install stoplight stop lamp delay-action controller additional, remind the vehicle of back to note, for the battery-driven car traffic safety, very large Practical significance is arranged.The present invention is after battery-driven car installs controller for delayed turn-off of brake light of electric car additional, can allow the electric vehicle brake lamp as the small passenger car stoplight stop lamp, time delay stoplight stop lamp in 1～2 second just can extinguish again after brake system resets, for reminding the vehicle after closelying follow, note, can effectively avoid the generation of vehicle rear-end collision accident, increase the battery-driven car traffic safety, this is to reducing the good effect of having of this type of traffic accident.
Below describe controller for delayed turn-off of brake light of electric car of the present invention relates in implementation process correlation technique content in detail.
Summary of the invention
Goal of the invention and beneficial effect: most of battery-driven cars do not have the stoplight stop lamp job procedure that the camera motor-car is the same on the market, a potential safety hazard when this has just formed fast running, so on battery-driven car, install stoplight stop lamp delay-action controller additional, remind the vehicle of back to note, for the battery-driven car traffic safety, very large Practical significance is arranged.The present invention is after battery-driven car installs controller for delayed turn-off of brake light of electric car additional, can allow the electric vehicle brake lamp as the small passenger car stoplight stop lamp, time delay stoplight stop lamp in 1～2 second just can extinguish again after brake system resets, for reminding the vehicle after closelying follow, note, can effectively avoid the generation of vehicle rear-end collision accident, increase the battery-driven car traffic safety, this is to reducing the good effect of having of this type of traffic accident.
Circuit working process: when battery-driven car normally travels, the about 5V high level of brake cable output due to brushless motor controller, NPN type aerotron VT1 is in conducting state all the time, at this moment on chemical capacitor C1, substantially there is no vdc, NPN type aerotron VT2 and NPN type aerotron VT3 can not get bias voltage and end, and the upper no-voltage of stoplight stop lamp HL1～HL2 is not worked; When electric vehicle brake, brake cable output becomes low level, make NPN type aerotron VT1 cut-off, when chemical capacitor C1 charges rapidly by resistance R 2, give NPN type aerotron VT2 and NPN type aerotron VT3 bias voltage, make NPN type aerotron VT2 and NPN type aerotron VT3 conducting, stoplight stop lamp HL1～HL2 has electric current to flow through, and at this moment stoplight stop lamp HL1～HL2 is lit.After the releasing of brake handle, vdc on chemical capacitor C1 can not discharge rapidly, vdc on chemical capacitor C1 is through discharging for 1～2 second, after stoplight stop lamp HL1～HL2 being lighted remained for 1～2 second, extinguish, then NPN type aerotron VT1 recovers again conducting, NPN type aerotron VT2 and NPN type aerotron VT3 end again, stoplight stop lamp HL1～HL2 is in and extinguishes state, thereby reach the purpose that electric vehicle brake is indicated.
