Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is specifically described.
As shown in Figure 1, a kind of electric vehicle braking of the present utility model assists intelligent system, the wheel speed sensors group for detecting car speed comprising entire car controller and be connected with this entire car controller, for detecting the groups of acceleration sensors of vehicle acceleration, for realizing the brake controller of car brakeing, for realizing the auxiliary braking subcontrol of car brakeing, for realizing the electrokinetic cell controller of Vehicle Power supply, for driving the drive motor controller of vehicular drive motor, Lighting Controller, photoelectricity sound alarm unit and the onboard wireless communication unit for realizing radio communication.
Described brake controller is also connected with car side brake and the braking mode sensor group for detecting wheel brake status.Described entire car controller is also connected with boosting battery, and this boosting battery is also connected to described electrokinetic cell controller.Described entire car controller is also connected with brake pedal.
Embody rule example of the present utility model is as follows:
As shown in Figure 1, a kind of electric vehicle braking assists intelligent system, by what work together with optoelectric alarm, in-vehicle wireless communication system etc. in vehicle control unit of electric vehicle, one group of wheel speed sensors, one group of acceleration pick-up, one group of vehicle corner sensor, brake controller, power cell of vehicle group controller, vehicular drive electric machine controller (possessing drived control and dynamic brake controlling functions), Lighting Controller, car.
When detecting discovery vehicle disconnection driving power and slowing down, the auxiliary intelligent system of braking automatically contacts entire car controller immediately and calls brake controller by the latter and realizes being responsible for implementing braking by the latter, intelligent system is assisted automatically to combine entire car controller implementing monitoring and automatically send regulation and control instruction by this braking, namely after braking starts, this braking assists intelligent system to utilize entire car controller by the moving velocity of wheel speed sensors group and groups of acceleration sensors automatic detection vehicle and deceleration/decel numerical value, when certain or two that find in deceleration/decel numerical value and rate of change thereof are more than or equal to the threshold value preset separately
a1 He
arwhen 1, this braking assists intelligent system automatically to contact brake controller by entire car controller immediately, and makes vehicle braking force reduce (to include but not limited to reduce certain numerical value of brake-pressure by the latter
dp1) certain numerical value preset
df1(includes but not limited to the corresponding numerical value obtained that calculates according to certain rules or table look-up), through the time value that presets
tafter 1, this braking assists intelligent system again to utilize entire car controller to continue to collect the numerical value of wheel speed sensors group and groups of acceleration sensors, thinks that certain or two in vehicle deceleration value and rate of change thereof are still greater than respective threshold value after judging
a1 He
arwhen 1, then the auxiliary intelligent system of braking allows entire car controller contact brake controller automatically, and makes braking force again reduce the numerical value preset
df1(includes but not limited to the corresponding numerical value obtained that calculates according to certain rules or table look-up), in whole braking deceleration process, as long as this braking assists intelligent system to detect discovery vehicle deceleration process deceleration/decel by entire car controller or its rate of change is bigger than normal, then constantly repeat said process, until deceleration/decel and rate of change thereof are all less than the threshold value of its correspondence
a1,
ar1, or till vehicle stopping deceleration.
Be more than preferred embodiment of the present utility model, all changes done according to technical solutions of the utility model, when the function produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
