In function y IAn, be implied with IBn, ID and IS content, and IBn, ID and ISn do not participate in pattern function calculating, make its easier Modling model function, or pattern function are fairly simple; And if without digital signal, directly use IA, IB, ID, IS very not easily Modling model function, the pattern function of foundation is very complicated.In like manner, in function y IBn, digital signal is implied with IAn, ID and IS content, is the method for drawing for simplifying Modling model function.
The utility model difference controls boosted vehicle system and controls through ID, IS, IA and IB and these four pattern function that former key element matches and calculate, export and to control two control voltage signals that former key element matches with these four respectively to the motor of front-wheel and trailing wheel, even if make wheel A and wheel B stressed unequal, also the work of two motor couplings can be obtained, the effect of two wheel balance motions.
When the former key element of identical ID, IS, IA and IB tetra-control is identical, as long as change the digital model function of setting, the different control signals that just can obtain multiple artificial setting export, solve and directly control two analog electronics by IA and IB two analog signals, only have a kind of mode, the shortcoming of mode can not be adjusted by human needs.
Whether stable state can be in leading rotational angle presumption bicycle, and by the size of leading rotational angle, the feedback control signal electric current I A produce cycle racing state and the difference delivery required by IB are revised, to ensure when bicycle plays pendulum, no longer labile factor is increased to bicycle, use morpet of the present invention more humane, safer.
