In order to increase the stability of electronlmobil automatic speed-changing system of the present invention, more preferably, described P shelves motor 3 is equipped with worm and gear self-locking mechanism (not shown), and described worm and gear self-locking mechanism circuit connects described P shelves electric machine controller.
When the present invention used, automatic transmission controller 25 was gathered shift handle D P PARK Position P signal, vehicle speed signal and shift fork to the P PARK Position P signal, and obtained the accelerator pedal signal (being the accelerator open degree signal) that entire car controller 28 is gathered by the CAN bus.Drive motor controller 26 is sent the torque rotary speed instruction to drive motor 2, and exports current tach signal.The vehicle speed signal that entire car controller 28 is gathered accelerator pedal signal in real time and gathered by automatic transmission controller 25 through the transmission of CAN bus, calculate the target torque of current drive motor 2, and issue drive motor controller 26 by the CAN bus, allow drive motor 2 these target torques of output.
The self shifter flow process sees also shown in Figure 6, and automatic transmission controller 25 calculates the current goal gear according to vehicle speed signal and accelerator pedal signal.When target gear and actual-gear are not inconsistent, need gearshift, automatic transmission controller 25 sends shifting commands by the CAN bus to drive motor controller 26, allows drive motor 2 freedom of entry patterns, shift motor 4 begins to rotate simultaneously, so gearshift axle 6 also rotates thereupon.Declutch shift shaft 7 can be moved along straight line for the quadrant gear of gearshift axle 6 lower ends and the engagement of the tooth bar on the declutch shift shaft 7.Shift fork 5 links together by resilient pin (not shown) and declutch shift shaft 7, with declutch shift shaft 7 motions.Drive range test rod 10 links together by spline and gearshift axle 6, rotates with gearshift axle 6.When shift fork 5 moves to neutral, buncher 32 is started working, input shaft 18 is adjusted to rotating speed of target, the actuating unit of shifting gears the then action that begins to shift gears, when shift fork 5 moves to the target location, shift fork detects position signal to P PARK Position P signal pickup assembly 35, so shift motor 4 outages stop operating.Shift motor 4 is equipped with worm type of reduction gearing, and realize self-locking by worm and gear this moment, makes shift fork 5 remain on the target gear and is unlikely to off-gear.Send the gearshift END instruction again and allow drive motor 2 switch to torque mode, so whole shift process finishes by drive motor controller 26.By this kind mode, realize coordination good between each controller.
In order to reduce the development difficulty of total system, and in conjunction with actual conditions, native system adopts 2 shift automatic transmission systems, when needs were shifted gears, shift fork 5 constantly switched between 1 retaining, N retaining and 2 gears are put under the driving of gearshift actuating unit, allow different gear transmission power, thereby change transmitting ratio.
Because in shift fork 5 traveling process, gearshift power in order to reduce the impact of automatic transmission with hydraulic torque converter 1 in shift process, improves shift quality in continuous variation, needs control gearshift power and shift speed in real time.Install gearshift Shaft angle sensor additional, this sensor is installed on the gearshift cover plate 8 and cooperates the corner that is used to detect gearshift axle 6 with gearshift axle 6 for this reason.Thereby the position of rotation that utilizes gearshift Shaft angle sensor to detect shift motor 4 in real time calculates synchro shift fork 5 positions in real time, thereby controls the output torque of shift motor 4 in real time, satisfies the ride comfort requirement of gearshift.
In addition, utilize motor to be easy to the characteristics of speed governing, what the present invention adopted is no-clutch self shifter technology, in shift process, adopts input shaft 18 rotating speeds of 32 pairs of automatic transmission with hydraulic torque converters 1 of buncher to regulate, the shock extent when reducing gearshift greatly.
In order to make the safer Parking of electronlmobil energy, the present invention has also adopted automatic parking system.When elec. vehicle stopped, the speed of a motor vehicle was zero, and chaufeur is transferred to the P retaining to shift handle from the D retaining.Described entire car controller 28 sends to described P shelves electric machine controller with described vehicle speed signal, described P shelves electric machine controller is by described gear shifting handle P P PARK Position P sensor acquisition gear shifting handle P P PARK Position P signal, when described gear shifting handle P P PARK Position P signal aspect and indication gear shifting handle is positioned at P shelves and described vehicle speed signal and is zero, the described P shelves of described P shelves motor controller controls motor 3 rotates, so P gear shaft 21 rotates thereupon, P retaining ratchet 15 begins to move downward under the pressure of elasticity pre-tightening mechanism 20.The P gear is put test rod 23 and is linked together by spline and P gear shaft 21.When P gear shaft 21 rotated to certain position, the P gear was put test rod 23 and is detected the arrival target location, so 3 stalls of P retaining motor.P retaining motor 3 is equipped with the worm type of reduction gearing (not shown) equally, realizes self-locking by worm and gear, keeps fixing when the front motor position of rotation.P retaining ratchet 15 with ratchet 16 engagements, is realized the locking to the output shaft 14 of automatic transmission with hydraulic torque converter 1 under the promotion of elasticity pre-tightening mechanism 20.If P retaining ratchet 15 does not have to arrive just the groove location of ratchet 16.Under the predetermincd tension effect of elasticity pre-tightening mechanism 20, rotate as long as ratchet 16 has slightly so, P shelves ratchet 15 will slip in the groove of ratchet 16, realizes the locking to the output shaft 14 of automatic transmission with hydraulic torque converter 1.When if chaufeur will start automobile, when chaufeur the shift handle position when P retaining is removed, the described gear shifting handle of described gear shifting handle P P PARK Position P signal aspect and indication is not positioned at the P shelves and described vehicle speed signal is non-vanishing, the described P shelves of described P shelves motor controller controls motor 3 backward rotation, so P shelves ratchet 15 breaks away from ratchet 16, removes the locking to the output shaft 14 of automatic transmission with hydraulic torque converter 1.When P retaining motor rotated to the target gear, the P gear was put test rod 23 and is detected the arrival target location, stopped operating so P keeps off motor 3, and utilized the worm-and-wheel gear self-locking, stopped at this position.In order to realize the two-way rotation of motor, the present invention adopts H bridge drive circuit module.
Adopt electronlmobil automatic speed-changing system of the present invention, greatly improve the dynamic property and the economy of electronlmobil, the requirement of driving motor for electric automobile 2 is reduced greatly, this has crucial meaning to the market competitiveness that improves electronlmobil.In addition, the automatic parking system in this system satisfies travel vehicle condition and driver intention, is used with parking brake, improves electronlmobil Parking reliability greatly.
To sum up, electronlmobil automatic speed-changing system of the present invention can initiatively adapt to the road surface variation and drive needs according to electric automobile during traveling situation automatic switchover gear, thereby the work area of drive motor is enlarged, guarantee that drive motor always can be operated in ideal region, thereby improve the dynamic property and the economy of electronlmobil, reduce the control difficulty of drive motor, reduce the batteries of electric automobile capacity, improve the cost performance of electronlmobil greatly, design ingenious, simple for structure, cost-cutting greatly, easy to use, be suitable for large-scale promotion application.
In this specification sheets, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
