7, low speed brake:
During vehicle low speed, if the restricted engine minimum speed output of its transmission gearbox cuts off the function of engine power, for example vee-belt speed-changing mechanism or centrifugal clutch dynamical element, then during low speed, vehicle inertia power can not be delivered to engine, must absorb vehicle inertia power this moment with mechanical brake, but controller still will cut the engine and stop for fuel oil, to reduce disposal of pollutants:
If transmission gearbox can not limit the minimum speed of engine, then Ci Shi brake control policy is the same with brake control policy in the high-speed travel.
Vehicle start when 8, battery electric quantity is not enough:
When the battery electric quantity deficiency, can't drive electrical motor with electric power, must start engine ignition this moment with manpower, generally makes to tramp with one's feet or hand scroll actuating mechanism drive engine; This moment, electrical motor kept idling conditions; After engine ignition running, vehicle drives with engine power fully and quickens, when the speed of a motor vehicle reaches certain value, and enough powered vehicle simultaneously of engine's motive power and be used for generating, this moment, controller switched to generator for electricity generation with electrical motor, charged into battery; When battery electric quantity was lower than a certain setting value, when vehicle stopped in advancing or brakes, engine was all not flame-out, and keeps running down: in order to avoid vehicle can't be again with power start.
Generating when 9, stopping:
Under special situation, can design change-over switch, with artificial replacing control system, make engine when stopping, still keep idling, and make electrical motor keep the electrical generator state, in the mode of power-transfer clutch mode or built on stilts vehicle, allow engine power can not reach ground, then can artificially refuel and improve engine speed and generate electricity, supply the demand of vehicle special the time, this function still can be finished easily by the utility model.
