As shown in Figure 2, speed automatic control method according to an embodiment of the invention, comprising: step 202, the driving information of Real-time Obtaining battery-driven car, judges that battery-driven car is the need of acceleration according to driving information; Step 204, if desired accelerates, then improve the rotating speed of the drive motor of battery-driven car, to promote the moving velocity of battery-driven car, until moving velocity equals pre-set velocity; Step 206, accelerates if do not need, then maintains the current rotating speed of drive motor.
Can analyze by the ride driving information of battery-driven car of user in real, thus determine according to current driving information the scheme adjusting the speed of a motor vehicle, and then the speed of a motor vehicle is adjusted to is consistent with driving information, thus make user can with fast running in the environment of riding of smoothness, lower-speed state can be maintained again when road conditions are poor, both ensure that the experience of riding of user, in turn ensure that the riding safety of user.
Preferably, step 202 comprises: step 2022, detects the voltage of control handle and the rotating speed of drive motor of battery-driven car in real time, judge whether voltage is more than or equal to predeterminated voltage, and whether rotating speed is more than or equal to preset rotation speed; Step 2024, if voltage is more than or equal to predeterminated voltage, and rotating speed is more than or equal to preset rotation speed, then recording voltage is more than or equal to predeterminated voltage, and rotating speed is more than or equal to the time length of the state of preset rotation speed; Step 2026, compares time length and Preset Time, if time length is more than or equal to Preset Time, then judge that battery-driven car needs to accelerate, if time length is less than Preset Time, or voltage is less than predeterminated voltage, or rotating speed is less than preset rotation speed, then judge that battery-driven car does not need to accelerate.
Only in the control of battery-driven car, voltage is more than or equal to predeterminated voltage, the rotating speed of drive motor is more than or equal to preset rotation speed, and battery-driven car maintain control voltage is more than or equal to predeterminated voltage, when being more than or equal to Preset Time under the state that the rotating speed of drive motor is more than or equal to preset rotation speed, just judge that battery-driven car needs to give it the gun, when above-mentioned three conditions all meet, illustrate that user travels (drive motor rotating speed is larger) with fast speed, and user is still carrying out accelerating (to control voltage is larger, illustrate that user twists that to control the dynamics of handle larger), and this situation continue for a period of time again, so illustrate that user now needs to travel with acceleration mode, thus automatic control electric motor-car accelerates, and carry out manual operation without the need to user, make user attentively can control battery-driven car to travel, both improve experience of riding, turn improve the safety of riding.
And when above-mentioned three conditions can not meet simultaneously, then battery-driven car does not give it the gun, by the common judgement of many condition, improve the accuracy of intelligent decision result.
Such as in battery-driven car upward slope process, even if control voltage to reach predeterminated voltage, but the rotating speed of drive motor is but difficult to reach preset rotation speed, and (such as preset rotation speed is 420 turns, run into uphill way rotating speed and then may drop to 360 turns), so now judge that battery-driven car does not give it the gun, thus guarantee that battery-driven car is in climbing process, drive motor has larger outgoing current, there is provided more high pulling torque for battery-driven car goes up a slope, make user sensuously in the process of slope battery-driven car still have sufficient power.
Again such as in the process of battery-driven car descending, even if the rotating speed of drive motor reaches preset rotation speed, but control when voltage is not reached predeterminated voltage, battery-driven car does not also give it the gun, the battery-driven car speed in descending process that avoids is too high and the potential safety hazard that causes.
Such as battery-driven car is in the process of moving again, the rotating speed of voltage and drive motor is controlled all to reach preset value, but time length do not reach Preset Time (that is battery-driven car be in control high potential and the high-revolving state for time of drive motor shorter, illustrate that user just needs speed-raising in some section, and be not suitable for long distance and run at high speed), then battery-driven car does not also give it the gun automatically, both ensure that the experience of riding of user, in turn ensure that the riding safety of user.
It should be noted that, above-mentioned Preset Time, predeterminated voltage, preset rotation speed all can be arranged by user as required, thus meet which kind of situation of user and automatically accelerate, and which kind of situation is recovered normal speed and travelled.
Preferably, step 204 also comprises: rise in the process of pre-set velocity at moving velocity, the voltage of control handle of real-time detection battery-driven car and the rotating speed of drive motor, judge whether voltage is more than or equal to predeterminated voltage, and whether rotating speed is more than or equal to preset rotation speed, if voltage is less than predeterminated voltage, or rotating speed is less than preset rotation speed, then the rotating speed of drive motor is down to current rotating speed.
By in battery-driven car accelerator, continue to detect the control of battery-driven car the rotating speed of voltage and drive motor, and in control, voltage is less than predeterminated voltage, or the rotating speed of drive motor is when being less than preset rotation speed, the rotating speed of drive motor is down to current rotating speed (rotating speed before acceleration), such as battery-driven car is after automatic decision accelerates, run into uphill way, so now battery-driven car will no longer accelerate, but travel with comparatively low velocity, to export more big current, more high pulling torque is provided to go up a slope, such as battery-driven car is after automatic decision accelerates again, run into descending section, so now battery-driven car also will no longer accelerate, but travel with comparatively low velocity, thus ensure that the riding safety in user's descending process.
It should be noted that, the decision state automatically accelerated is that user is controlled, and user can control to be in acceleration mode all the time under any condition, does not enter acceleration mode under also can being arranged on any condition.
Preferably, also comprise: the dump energy detecting the power supply of battery-driven car in real time, when dump energy is lower than default electricity, working on the time of record drive motor, to work on time and preset operating time compares, and when the time of working on is more than or equal to preset operating time, automatic control power supply is powered to drive motor with predeterminated voltage, wherein, predeterminated voltage is lower than the rated voltage of power supply.
If the current dump energy of battery-driven car is lower than default electricity, namely when the electricity of electric vehicle power sources is not enough, by judging that the time of working on of drive motor judges that user is the need of continuing a period of time of riding, when determining user and needing to continue to ride, the output voltage of automatic reduction power supply, to ride larger distance to battery-driven car to ensure that dump energy can be used for.Specifically, when the dump energy of power supply is lower than default electricity, low electricity alerting signal can be sent, now, if battery-driven car continues to travel, and running time (i.e. drive motor work on the time) is greater than default work-hours, then can judge that user needs battery-driven car to continue to travel, thus automatically reduce the output voltage of electric vehicle power sources, and when power supply is less than rated voltage to the voltage that drive motor is powered, can guarantee that battery-driven car travels larger distance, ensure that the distance of riding of user.
