The specific embodiment
Multi-motor drive control system of electric vehicle, structure comprises the substrate 1 being fixed on car body and is arranged on the governor gear on substrate 1, and key is: described governor gear comprises left acceleration/deceleration signal collector 2 and the right acceleration/deceleration signal collector 3 being symmetricly set on slide block 4; Slide block 4 forms bearing fit by means of slideway 5 and substrate 1, and Das Gaspedal bracing wire 12 is connected with slide block 4 with accelerator oil rest extension spring 13; Speed governing bracing wire is drawn from left acceleration/deceleration signal collector 2 adjustment disk 6 Opposite direction connections that are arranged on control substrate 1 by dead axle and is formed synchronous anti-phase differential Signal Regulation structure at right acceleration/deceleration signal collector 3 corresponding sites; The left and right speed control signal output line 14,15 that left and right acceleration/deceleration signal collector 2,3 is drawn sends to motor or electric machine controller by control signal.Left acceleration and deceleration bracing wire 7 and right acceleration and deceleration bracing wire 8 have formed speed governing bracing wire.
The multi-motor drive control system of electric vehicle of a kind of and above-mentioned adjustment disk 6 and two acceleration/deceleration signal collector position-reversed designs, key is: adjustment disk 6 is arranged on slide block 4 by rotating shaft, left and right acceleration/deceleration signal collector 2,3 are positioned on control substrate 1, adjustment disk 6 forms the synchronous anti-phase differential Signal Regulation structure of above left and right acceleration/deceleration signal collector 2,3 by the transmission of second direction pull bar 17 and the second fork 18.
The driving of adjustment disk 6 is by the deceleration fluted disc 16 with supporting transmitting ratio being connected with steering wheel, or forms coaxial rotation structures by the first fork 9 with chute with the first direction pull bar 10 of supporting pulley with adjustment disk 6.
In the connection of speed governing bracing wire and left and right acceleration/deceleration signal collector 2,3, be reserved with looseness gap, parking direction dead angle.
Above-mentioned left and right acceleration/deceleration signal collector 2,3rd, Hall element or resistance regulator or voltage regulator or current relay, above four kinds of collectors are sent to the analog signal collecting in electric machine controller respectively.
In above-mentioned system, be also provided with central processing unit, central processing unit receives signal that left and right acceleration/deceleration signal collector 2,3 collects, after analogue to digital conversion, quantitative analysis are processed, and speed controling signal is directly sent to motor.
In above-mentioned system, be also provided with central processing unit, central processing unit receives signal that left and right acceleration/deceleration signal collector 2,3 collects, after analogue to digital conversion, quantitative analysis are processed, and speed controling signal is directly sent to motor.
As shown in Figure 1 and Figure 2, enumerated the embodiment of two kinds of steering driving mechanisms.When chaufeur bearing circle is turned left, the first bayonet lock 11 that Steering gear connects on reducing gear 16 or first direction pull bar 10 connects the first fork 9 drive adjustment disks 6 rotary oscillation left, the right acceleration and deceleration bracing wire 8 of right acceleration/deceleration signal collector 3 is drawn out, right speed control signal output line 15 is electric machine controller output Acceleration Signal to the right, and each motor of right side increases rotating speed; And left acceleration and deceleration bracing wire 7 retractions of left acceleration/deceleration signal collector 2, left speed control signal output line 14 is electric machine control output restriction signal to the left, and each motor of left side reduces rotating speed, and vehicle is easy to safely and smoothly turn round left.
When chaufeur bearing circle bends to right, the working process of speed-regulating signal producer is contrary with said process, reducing gear 16 or the first fork 9 connect adjustment disk 6 rotary oscillation to the right, the left acceleration and deceleration bracing wire 7 of left side acceleration/deceleration signal collector 2 is drawn out, left speed control signal output line 14 is electric machine controller output Acceleration Signal to the left, and each motor of left side increases rotating speed; And right acceleration and deceleration bracing wire 8 retractions of right side acceleration/deceleration signal collector 3, right speed control signal output line 15 is each electric machine controller output restriction signal to the right, and each motor of right side reduces rotating speed, and vehicle is easy to safely and smoothly turn round to the right.
When vehicle gives it the gun, chaufeur step on the gas pedal pulls slide block 4 to move along slideway 5 by Das Gaspedal bracing wire 12, to car load, accelerates; During accelerator releasing pedal, because accelerator oil rest extension spring 13 one end are fixed on substrate 1, the other end is fixed on slide block 4, and therefore meeting automatic retracting slide block 4, is that car load slows down.Setting by Das Gaspedal bracing wire 12 with adjustment disk 6, acceleration and deceleration operation operation when can make multi-motor drive control system of electric vehicle realize turn inside diameter.
Referring to Fig. 3, above-mentioned the first fork 9, the first pull bar 10 and the first bayonet lock 11 also can adopt the structure in Fig. 3, respectively corresponding the second fork 17, the second pull bar 18 and the second bayonet lock 19 in Fig. 3.In this structure, left and right acceleration/deceleration signal collector 2,3 are fixed on control box, and adjustment disk 6 is fixed on slide block 4, other structure is constant, because the second fork 17 adopts inverted plug type, so left speed control signal output line 14 connects vehicle right motor controller, right speed control signal output line 15 connects vehicle left side electric machine controller, realizes the rotating speed differential of left and right sides drive motor by such reversal connection.This enforcement structure is along with the plus-minus of car speed, and adjustment disk 6 is also synchronizeed and increased or reduce with the distance of second direction pull bar 18; When car speed is low, the second fork 17 slip ranging coverages are short, and adjustment disk 6 rotary oscillation amplitudes are just large, and differential, than just large, be easier to vehicle low speed wide-angle and turn.When car speed is high, the second fork 9 slip ranging coverages are long, and adjustment disk 6 rotary oscillation amplitudes are just little, and differential is less than just, are conducive to the steady and safety of high vehicle speeds.
In above 3 kinds of embodiment, must be all will be at adjustment disk 6 and left and right acceleration/deceleration signal collector 2, between 3, leave looseness gap, parking direction dead angle, in electric automobile during traveling process, when may there is non-refuelling door but making automobile touch coast, now there is no need to control the differential of two trailing wheels, the differential of two trailing wheels is to rely on automobile inertial spontaneous combustion to form differential, even chaufeur steering wheel rotation, but the existence due to looseness gap, can not remove to control the differential of two trailing wheels by output signal, so looseness gap must be set.For example, in Fig. 1, when Das Gaspedal bracing wire 12 is unclamped, slide block 4 is reset mode by accelerator oil rest extension spring 13, and left acceleration and deceleration bracing wire 7 now and right acceleration and deceleration bracing wire 8 are in relaxed state, and the rotation of adjustment disk 6 can not trigger two acceleration/deceleration signal collectors.
