Abstract
The invention provides a control technology for an electric motor car with a nature boost function. The nature boost function is a pedal force-load current control technology, i.e., the pedal force of a rider is taken as a given control quantity, the load current is taken as a feedback control quantity, and velocity magnitude is directly taken as an auxiliary feedback control quantity inside the system when a stepless boost proportion given quantity is introduced, so as to cause the 'boost' functional gear to realize the force and speed coordination between the rider and the electric motor car, therefore, the force of the rider and electric force are complementary and interdependent organically.
Description
Affiliated technical field
The present invention relates to a kind of electric motor car with two wheels control technology control technology for electric motor car under the assist function specifically.
Background technology
Battery-driven car is as the nuisanceless green vehicle of emission-free, noise-free environmentally-friendly, civilization and do not consume non-renewable resources, save the resource-conserving vehicle of public space, is being subjected to people's welcome.One of them welcome point, " power-assisted " function of the retaining that is exactly that battery-driven car has a kind of " power-assisted " makes people ride, drive convenient to both, adds the needs that satisfied way far away travel, has and has satisfied the needs of taking exercise.Yet, " power-assisted " function of current battery-driven car, and nonessential power-assisted, but a kind of speed servo-actuated.It controls motor speed by detecting the chain drum rotating speed, and what the person's of riding both feet play a part is velocity setting, and the power that scrunches of its both feet and the operation of car are irrelevant.That is, electrical motor is the main force for the people, rather than " power-assisted ".Certainly will cause two kinds of situations like this: the one, because people's load force sensation has been ignored in this speed servo-actuated, the people has also lost load force sense and the speed sense of itself simultaneously, thereby speed is out of control, and then causes and drive the traffic accident that causes out of control, particularly causes big current work infringement battery during high speed; The 2nd, because by a driving inconvenience that causes or uncomfortable, battery-driven car should " power-assisted " function can be replaced by its function of tonic chord (" electronic " retaining) fully simultaneously, battery electric power completely loses " power-assisted " function again when not enough, thereby should " power-assisted " function be left unused without hesitation.For this reason, must improve this technology, achieve " power-assisted " function of essence, promptly, it is given controlling quantity that bicyclist's both feet are scrunched masterpiece, and as the controlled reset amount, and speed is only as internal system controlled reset amount with load current, in the hope of realizing that power, speed between people, the car coordinates, manpower, electric power complementation, help each other.
Summary of the invention
For improving this defectiveness technology of current battery-driven car " power-assisted " function retaining, achieve " power-assisted " function of essence, the invention provides a kind of foot-operated power-load current control technology.Promptly, it is given controlling quantity that bicyclist's both feet are scrunched masterpiece, with load current as the controlled reset amount, and when introducing stepless power-assisted ratio specified rate, the speed amount is directly as the auxiliary controlled reset amount of internal system, make " power-assisted " function retaining realize that power, speed between people, the car coordinates with this, manpower, electric power organic complementary, help each other.
The technical solution adopted for the present invention to solve the technical problems is: by being installed in the pressure sensor on driving chain top, the both feet that obtain the bicyclist scrunch force signal, and should ride masterpiece is given controlling quantity; Set up the given input of stepless power-assisted ratio, obtain the torque signals that scrunches under the given power-assisted ratio, introduce load current signal simultaneously as motor load torque controlled reset amount, through relatively obtaining " power-assisted " function retaining pedal power-motor load power down, be manpower-electric power departure, as torque control signal; Do not re-use the existing down velocity setting signal of this function retaining and the comparing element of velocity setting signal and feedback speed signal, feedback speed signal is directly introduced the comparing element with torque control signal, through relatively obtaining comprehensive bias control signal, control input as torque deviation control ratio governing loop under this function retaining, control follow-up link operation, its effect is similar to existing technology.
During operation, bicyclist's both feet that pressure sensor obtains scrunch power through amplifying with the ratio amplifying element, obtain the torque signals that scrunches under given power-assisted ratio, through comparing with motor load torque controlled reset amount, obtain manpower-electric power departure, i.e. torque control signal; This controlling quantity and existing velocity feedback quantity compare, and obtain comprehensive bias control signal, this departure through amplify, control, make Electronmotive Force giving certainty ratio " power-assisted ", and running speed depends on this departure, environment and cell pressure; When cell pressure is higher, the proportional control amount allows less departure to obtain higher magnification factor, through driving governor control, amplification, make the higher proportion (be lower than to certainty ratio) " power-assisted " of Electronmotive Force to be proportional to cell pressure, so that almost near giving certainty ratio, the speed of a motor vehicle also can be very high; When cell pressure is low, even if departure is bigger, the proportional control amount also can be by regulating magnification factor, make that the drive controlling amount is less, through driving governor control, amplification, regulate Electronmotive Force with low ratio (far below giving certainty ratio) " power-assisted ", the speed of a motor vehicle then may be very low, and bicyclist's both feet power that scrunches almost becomes " main force "; And when cell pressure hangs down to " under-voltage " value, existing under-voltage protection function operation, car body is advanced and is driven by bicyclist's both feet power that scrunches fully.
The invention has the beneficial effects as follows: can make battery-driven car realize that at " power-assisted " function retaining power, speed between people, the car coordinates, manpower, electric power organic complementary, help each other, can take the operation and the mode of operation of existing controller simultaneously again into account.
