This electric vehicle selects velocity modulation speed variator to insert car key from vehicle stationary state driver and begins to work, namely after driver does not use accelerator pedal, brake pedal and unclamps parking brake, if now it clicks certain speed button in selector then pressing and moves ahead or back, this described choosing speed speed regulating method and system thereof just automatically calculate and judge how much vehicle speed will reach, which kind of accelerated motion vehicle will carry out and relevant acceleration rule and acceleration parameter thereof are passed to entire car controller；After entire car controller receives vehicle target speed, acceleration, acceleration rule and acceleration parameter, first pass through longitudinal separation sensor at once and obtain vehicle longitudinal separation information, guaranteeing that vehicle can continue in safety traffic situation, entire car controller is automatically changed the drive motor of calculation and accelerates rule accordingly and pass to drive motor controller with acceleration parameter, and driven by the latter, control drive motor accelerated motion, thus vehicle acceleration rule on request is driven to accelerate；τ 1 at set intervals, this entire car controller just collects longitudinal separation sensor about vehicle longitudinal separation information, guaranteeing that vehicle can continue in safety traffic situation, entire car controller compares vehicle real-time speed and expection accelerator car speed difference degree the necessary adjustment being driven motor control law and controlled quentity controlled variable through detection, then allow drive motor controller control target drives motor by the acceleration just revised accelerate, it is achieved vehicle accelerates；This process constantly repeats, until speed reaches the preset speed of driver and keeps it from only becoming.After vehicle reaches the speed that driver is preset, τ 1 at set intervals, this entire car controller just collects longitudinal separation sensor about vehicle longitudinal separation information, guaranteeing that vehicle can continue in safety traffic situation, allow drive motor controller keep controlling drive motor by the driving moment just now finally determined move with uniform velocity, make vehicle keep preset speed at the uniform velocity move ahead or retreat.
For ensureing that vehicle gently accelerates to preset speed, minimizing accelerator vehicle and drive motor and drive system is impacted and the saving energy, τ 1 at set intervals, entire car controller by detect wheel detector group speed and calculating after with regard to automated intelligent judge this vehicle can in the scheduled time, by this drive motor by whether the control target drives vehicle of just corrected acceleration rule and parameter thereof can gently accelerate to its preset speed.If judge it is found that, this entire car controller just no longer revises the Controlling object function of drive motor controller, and allows drive motor controller continue to work by its control law drive motor, continues accelerating vehicle；If judging to find to continue so to accelerate to make vehicle gently accelerate to preset speed in the scheduled time, this entire car controller just revises the acceleration Controlling object function of drive motor immediately, and make drive motor controller correspondingly adjust the control parameter of motor by this revised control target, and with this drive motor and vehicle.As long as the speed that car speed is preset not up to driver, this process just repeats always, reaches till driver arranges numerical value until speed.Fig. 4 be end to end each one section identical but be that the two-stage nitration parabola vehicle of a skew lines accelerates rule and acceleration parameter towards contrary parabola, centre.In Fig. 4, t1 is for accelerating start time, and corresponding driver selects velocity modulation speed system to calculate the moment after judging by after choosing speed button, and t2 is the parabola end of boost moment, from moment t1 to t2, acceleration from 0 parabolically rule progressively increase to maximum a1；From moment t2 to t3, vehicle does uniformly accelerated motion by acceleration a1；From moment t3 to t4, vehicle acceleration rule parabolically is gradually reduced to 0 by maximum a1, speed then accelerates to the speed that driver is preset.
This electric vehicle selects the velocity modulation speed variator mode by keyboard scan, it is judged that determine the true choosing speed requirement of driver.Fig. 2 is in choosing speed button figure, the figure of this system, clicks △ 5 or △ 10 or △ 20 button, represents speed increment respectively 5km/h, 10km/h, 20km/h, clicks 5,10,20 buttons, then speed reduces 5km/h, 10km/h, 20km/h.Fig. 3 forms system with adding (subtracting) speed rule with parameter automated intelligent for choosing speed computer identification.No matter vehicle is from static, still in the process of moving, as long as driver clicks the choosing speed button of Fig. 2 and moves ahead or back, this electric vehicle choosing speed speed regulating method and system thereof just can identify driver at once and to accelerate or deceleration demand, and calculates acceleration curve and the acceleration parameter judging to be correlated with immediately.Fig. 4 is that vehicle accelerates rule and acceleration parameter, and Fig. 5 is vehicle deceleration rule and deceleration parameters.Impacting and saving energy for alleviating acceleration and deceleration process, this electric vehicle choosing speed speed regulating method adopts identical two sections of parabolas, the even acceleration curve adding (subtracting) speed oblique line of middle employing or deceleration curve end to end.In this electric vehicle choosing speed speed regulating method and system thereof, most this value of high acceleration a1(of the vehicle that prestores can according to the animus novandi of car owner).When driver selects press up-to-date speed button and move ahead or during back, this electric vehicle choosing speed speed regulating method and system by the most energy-conservation principle automated intelligent of accelerator calculate parabolic curve and and relevant parameter, and these are added (subtracting) speed curve and parameter pass to entire car controller.Obtain vehicle real-time add (subtracting) speed curve and parameter after, entire car controller automatically convert calculate drive motor or brakes drive target (or braking target) function accordingly, and these new driving target (or braking target) functions are passed to drive motor controller (or brake system controller).
When the speed that the speed button that driver finally selects is corresponding speed current less than vehicle, to do Reduced Speed Now at this electric vehicle choosing speed speed regulating method and system automatic decision vehicle thereof and its calculated relevant deceleration parabolic curve and parameter thereof are passed to entire car controller；After acquisition vehicle to do retarded motion and deceleration rule thereof, entire car controller then calculates the output torque judging whether only to need to reduce drive motor at once automatically just can meet the deceleration demand of vehicle.If entire car controller judges that only needing to adjust the output torque controlling drive motor just can meet vehicle by the deceleration curve deceleration demand of double-paraboloid line end to end, motor vehicle braking system is not then allowed to participate in decelerating operation, now, after associating drive motor controller makes vehicle decelerate to preset speed by the deceleration curve of this double-paraboloid line end to end, maintain drive motor control target constant under work on, try hard to make vehicle travel at the uniform speed under this velocity amplitude.If entire car controller calculates the output torque judging only to turn down drive motor cannot meet the vehicle deceleration demand by double-paraboloid line deceleration curve end to end, then directly invoke brake monitor, and carry out passing to brake monitor as its object function after necessary conversion calculates using deceleration curve and the parameter thereof of this line of double-paraboloid end to end formed in real time, and vehicle is made to slow down on request by the latter.Carrying out in moderating process in brake, τ 1 at set intervals, entire car controller automatic detection vehicle is fast, whether judge vehicle by expection deceleration regular movement；If it is variant with expection deceleration rule to judge to find vehicle deceleration rule in real time, with regard to actively intervening, adjust the object function of brake monitor in time, make vehicle deceleration process close proximity to expection deceleration curve；As long as speed does not reduce to preset speed, this process just constantly repeats.
When vehicle deceleration to preset speed, entire car controller is making brakes out-of-work while, immediately preset target vehicle speed is changed into automatically the control target of drive motor, and by drive motor controller by the work of this control target drives motor, and car speed is made to maintain about this value.
Though vehicle be at the uniform velocity or accelerate move ahead or or fallback procedures in, τ 1 at set intervals, this entire car controller just automatically collect before (afterwards) range sensor about range information (afterwards) before vehicle, guaranteeing that vehicle can continue in safety traffic situation, allow drive motor controller keep rotating speed target (function) that is preset or that finally determine to control drive motor do at the uniform velocity or accelerated motion, make vehicle at the uniform velocity move ahead (or retrogressing) or accelerate.When calculate judge find vehicle continue by just now traveling rule it may happen that collision time, the target vehicle speed of vehicle is reduced half by this entire car controller immediately, the motor rotating speed of target that the speed of this minimizing changes into minimizing simultaneously immediately passes to drive motor controller, and make drive motor running parameter adjust accordingly by the latter, it is achieved motor and vehicle deceleration.τ 1 at set intervals, this entire car controller just again automatically collect before (afterwards) range sensor about range information (afterwards) before vehicle, when finding that vehicle still has collision dangerous, the target vehicle speed of vehicle is reduced half by this entire car controller immediately again, the motor rotating speed of target that the speed of this minimizing changes into minimizing simultaneously immediately passes to drive motor controller, and make drive motor running parameter adjust accordingly by the latter, it is achieved motor and vehicle deceleration.This process constantly repeats, till the calculating of this entire car controller judges that vehicle will not collide.
This entire car controller is also ined succession a trained sound detection and intelligent identifying system, for emergency emergency processing vehicle.When judging to find that driver or passengers inside the car repeat suddenly cry out brake or stop loudly, these emergency brake information can be passed to entire car controller by this system immediately, and cut off the power of drive motor immediately by the latter, allow brakes enter the duty of brake hard simultaneously.
When driver selects front line speed to exceed vehicle normal speed, this system restriction vehicle max. speed is less than its specified speed, namely specified speed and corresponding acceleration curve thereof are only passed to entire car controller by this electric vehicle choosing speed speed regulating method and system thereof, and are realized acceleration or the uniform motion of this max. speed by entire car controller monitoring drive motor controller.When driver selects vehicle rollback, if the speed of its selection is more than 30km/h, then the speed of 30km/h can only be passed to entire car controller and be realized acceleration or the uniform motion of 30km/h by entire car controller monitoring drive motor controller by this electric vehicle choosing speed speed regulating method and system thereof.After the vehicle of current line obtains the information of certain retrogressing speed of driver, this electric vehicle choosing speed speed regulating method and system thereof first pass through entire car controller and allow drive motor quit work by drive motor controller, allow brakes brake normally, until car speed reduces to zero simultaneously.Then, this electric vehicle choosing speed speed regulating method and system thereof allow drive motor drive vehicle to fall back with preset speed again through entire car controller by drive motor controller.
It is above preferred embodiment of the present utility model, all changes made according to technical solutions of the utility model, when produced function is without departing from the scope of technical solutions of the utility model, belong to protection domain of the present utility model.
