Abstract
The invention discloses a kind of electric vehicle brake control circuit, including controller braking power-off signal line, 12V accessory power supplys, steering indicating light, position lamp, brake lamp and brake switch, the brake lamp both ends connect 12V accessory power supplys positive pole and controller braking power-off signal line output terminal respectively, the brake switch connects controller braking power-off signal line output terminal and public negative pole respectively, it is characterised in that：A diode, the diode cathode connection controller braking power-off signal line output terminal, positive pole connection brake lamp are provided between the controller braking power-off signal line output terminal and brake lamp.The present invention passes through a diode being arranged between controller braking power-off signal line output terminal and brake lamp, block in no 12V accessory power supplys, controller brakes the transmission of power-off signal, so that normal vehicle operation can be ensured in the case where vehicle is without 12V accessory power supplys, and controller is not had any impact.
Description
Technical field
The invention belongs to whole-control system technical field, more particularly to a kind of in feelings of the vehicle without 12V accessory power supplys
The electric vehicle brake control circuit of normal vehicle operation can be ensured under condition.
Background technology
The existing most of electric vehicles of in the market are uneasy to save integral vehicle cost as shown in Fig. 2 using not bearing Brake lamp altogether
Fill brake relay.Though such design has saved the material and manufacturing cost of bundle assembly, while also saves vehicle
Material and manufacturing cost；But the design defect that vehicle vehicle when without 12V accessory power supplys is unable to normally travel be present（I.e. at vehicle
In brake off-position）.
The content of the invention
The object of the invention is directed to the defects of prior art offer one kind and can protected in the case where vehicle is without 12V accessory power supplys
Demonstrate,prove the electric vehicle brake control circuit of normal vehicle operation.
The present invention to achieve the above object, adopts the following technical scheme that：
A kind of electric vehicle brake control circuit, including controller braking power-off signal line, 12V accessory power supplys, steering indicating light, position
Lamp, brake lamp and brake switch are put, the steering indicating light both ends connect turning indicator control output end and public negative pole, institute's rheme respectively
Put lamp both ends difference link position lamp switch output end and public negative pole, the brake lamp both ends connect 12V accessory power supplys respectively
Positive pole and controller braking power-off signal line output terminal, the brake switch connect controller braking power-off signal line output respectively
End and public negative pole, it is characterised in that：One is provided between the controller braking power-off signal line output terminal and brake lamp
Diode, the diode cathode connection controller braking power-off signal line output terminal, positive pole connection brake lamp.
Preferably：The brake switch includes parking brake switch and service brake switch in parallel.
The steering indicating light includes left steering lamp and right turn lamp.
The controller braking power-off signal line output terminal is connected with a forward diode.
The present invention passes through a diode being arranged between controller braking power-off signal line output terminal and brake lamp, resistance
Break in no 12V accessory power supplys, controller brakes the transmission of power-off signal, so that in vehicle without 12V accessory power supplys
In the case of can ensure normal vehicle operation, and controller is not had any impact.
Brief description of the drawings
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is prior-art illustration.
Embodiment
A kind of electric vehicle brake control circuit as shown in Figure 1, including controller braking power-off signal line, 12V accessory power supplys,
Steering indicating light, position lamp 7, brake lamp 6 and brake switch；The controller braking power-off signal line output terminal is connected with a forward direction
Diode 1.The steering indicating light both ends connect turning indicator control output end and public negative pole respectively.The both ends of position lamp 7 difference
Link position lamp switch output end and public negative pole.The brake lamp both ends connect 12V accessory power supplys positive pole and controller respectively
Brake power-off signal line output terminal, the brake switch connects controller braking power-off signal line output terminal and public negative respectively
Pole.A diode 2 is provided between the controller braking power-off signal line output terminal and brake lamp 6, the diode 2 is negative
Pole connection controller braking power-off signal line output terminal, positive pole connect the common wire after two parallel connections of brake lamp 6.
The brake switch includes parking brake switch 3 and service brake switch 4 in parallel.The steering indicating light includes the He of left steering lamp 51
Right turn lamp 52.
When 12V accessory power supplys normally provide, brake switch closure, controller braking power-off signal is effective, and vehicle is in
Brake off-position, electric car can not be started, and brake lamp is lighted（Loop is：12V accessory power supply positive poles -- brake lamp-diode
2-brake switch -- public negative pole）.
When without 12V accessory power supplys, diode 2 has blocked the transmission of controller braking power-off signal, so that whole
Car without 12V accessory power supplys in the case of can ensure normal vehicle operation.When brake switch closes, controller brakes power-off signal
Effectively, vehicle is in brake off-position, and electric car can not start, but brake lamp does not work.
Claims (4)
