Step S34, control device will output to mechanical device, display unit and wind speed generator by aforementioned calculation model result calculated.Because the hypothesis cycling is on a route of being scheduled to, the resistance situation of everywhere, wind speed, road surface gradient and pavement behavior all are predefined on this route.So can calculate the current location of bicycle on projected route according to present speed signal and current direction signal.Compare the predefined parameter value of this position on current parameters (comprising resistance, brake weight, wind speed etc.) of bicycle and the projected route then, calculate the difference between them.Again difference is converted into corresponding output signal.Output to mechanical device, display unit and wind speed generator.
Step S35, mechanical device, display unit and wind speed generator are operated according to the result who receives.Describe the mode of operation of each parts in the mechanical device below in detail:
The mode of operation of charger: as cyclist by bike the time, speed increasing mechanism will be ridden speed and improve tens times, and the rotating speed that has improved drives torque sensor, tachometer generator, the rotation of loading servomotor simultaneously.Tachometer generator produces rate signal, asks monovalence to become acceleration signal in the rate signal input control device.
Pavement state signal and speed with current bicycle present position in the projected route, three signals of acceleration are sent into Mathematical Modeling in the control device as boundary condition, calculating by computer, resulting power output signal is as the command signal of system, be input in the charger, the positive and negative rotating speed and the torque of charger output current signal control servomotor, the rotation that loads servomotor generates moment, be applied to by torque sensor in cyclist's the step, the torque signals of torque sensor output is sent into charger simultaneously and is compared with above-mentioned force signal, the conclusion control that draws loads the servomotor torque, rotating speed, direction of rotation, thus realized the closed loop automatic control process of a power.So, during the cyclist, the sensation of foot-operated power has just been arranged.This loading method adopts the principle of leading rate signal 90 degree of acceleration signal, power is preceding, speed after, and make the loading method of the imperceptible front and back of cyclist, because load the servomotor rotation direction with direction is opposite by bike, so adopt this way to need more powerful loading servomotor, and load servomotor and under the situation of stall, work for a long time, burn servomotor easily.And powerful servomotor is once out of controlly can damage the cyclist.Therefore, in one embodiment, adopt the method for off-load.In system, add a constantly acting load in advance, identical and to go part preload, remaining load be cyclist's foot-operated power by bike with loading the servomotor rotation direction.
Because adopt the fast mechanism of tens multiplications, be that foot-operated speed makes loading servomotor rotating speed improve tens times under the inactive state, that is to say that the frictional force with servomotor has improved tens times.So with this masterpiece for adding a constantly acting load in advance.
When car during at level road:
Foot-operated power=pre-applied force-loading force
When car is going up a slope:
Foot-operated power=pre-applied force+loading force (when the gradient increased, loading force increased)
When car during at descending:
Foot-operated power=pre-applied force-loading force (when the gradient increased, loading force increased)
This loading method can make the smaller of load and execution mechanism manufacturing, with the moment of loading servomotor output also smaller, the range ability that torque sensor is selected for use is smaller, improved precision and response speed in proper order, the inertia of load maintainer itself, gap and frictional force are all little and the power scope of foot-operated feedback is bigger.And under runaway condition, can not work the mischief to the cyclist.
The mode of operation of tilting gearing: in identical handlebar angle, when turning with the different speed of a motor vehicle, the turning gradient of bicycle is different.When the cyclist turns by bike, data acquisition unit is current tilt signals and present speed signal input control device, computer calculates the control circuit that back output tilt signals is given tilting gearing, and control circuit control oblique servo motor begins rotation tilts " bicycle ".Simultaneously, angular displacement sensor outputs signal to the control circuit of tilting gearing, and two signal-balanced backs " bicycle " stop to tilt, and have reached required angle.
The method of operating of elevation mount: luffing mechanism is controlled by control device fully.As cyclist by bike the time, the gradient appears in the projected route, and the Mathematical Modeling of predetermined climb and fall signal input computer outputs to the control circuit of elevation mount behind the computer-solution, and control circuit pitching servomotor begins rotation makes " bicycle " pitching.Simultaneously, angular displacement sensor outputs signal to control circuit, and two signal-balanced backs " bicycle " stop pitching, to reach required angle.
The operating principle of vibrating device: vibrating device is controlled by control device fully.As cyclist by bike the time, uneven road surface appears in the projected route, it is the road surface that " ditch " arranged, in the Mathematical Modeling of Uneven road signal (being exactly the spacing of " ditch ") input computer, after calculating, computer outputs signal to the control valve of vibrating device, cylinder action before and after the control valve control, " bicycle " vibration that begins to jolt.When the speed of a motor vehicle was higher, the front and back cylinder moved simultaneously and makes " bicycle " leap.When the speed of a motor vehicle was low, the front and back cylinder successively moved " bicycle " is jolted.
The current location of the bicycle that display unit then calculates according to control device shows on the predetermined route to comprise pavement behavior, background image and weather condition etc. corresponding to the image of this position.These images all be in advance with projected route on each position one to one.
The wind speed generator obtains wind speed and direction herein on the projected route earlier according to the bicycle current location that control device calculates, and then in conjunction with current vehicle speed, direction, use foregoing formula to calculate, obtain current wind speed and direction, and the drive fan blowing.
Step S35 if control device receives end signal, just stops, otherwise gets back to step S32.
Owing to adopted technique scheme, jolting and various states such as leaping fast the time when preshoot when bicycle simulated equipment of the present utility model and method can be simulated brake, the pitching when broken up and down, tilting when turning, Uneven road, and generation and reponse system by installing various kinds of sensors, power additional, on virtual road surface, simulate various attitudes and movable information, thereby reach sensation on the spot in person for the cyclist.
The embodiment of above-mentioned detailed description provides to being familiar with the person in the art and realizes or use of the present utility model; those skilled in the art can be under the situation that does not break away from invention thought of the present utility model; the foregoing description is made various modifications or variation; thereby protection domain of the present utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
