hi i am noel need a literature survey on electromagnetic gear shifting mechanism for my project kindly help!

There are disclosed an automatic gear change control apparatus for an automobile and a
method of controlling such apparatus. A rotational output of an internal combustion engine is
connected to drive wheels of the automobile and a load device.
When a gear shifting-up of an automatic transmission is to be effected, the load applied by
the load device is increased, or the load is connected to an output rotation shaft of the engine via a
selectively-connecting device, thereby reducing the rotational speed of the output rotation shaft of
the engine to a required level. In this work, two electromagnetic coils are coupled to the gear rod of
the two ends. The two buttons are used to activate the electro-magnetic coil so that the gear will be
shifted.
1. INTRODUCTION
An automatic gear change control apparatus for an automobile, comprising an internal
combustion engine; an automatic transmission connected to an output rotation shaft of engine so as
to transmit the rotational output of drive wheels through any selected one of gear ratios; apparatus
comprising a load device for applying a load; means for connecting load device to output rotation
shaft of engine and for generating a gear change control signal for selecting one of gear ratios of
automatic transmission in accordance with one of operational conditions of automobile and said
engine; and load control means for increasing the load of said load device when said gear changesignal-generating means generates the control signal for shifting up the gear in automatic
transmission.
Increasing demands on performance, quality and cost are the main challenge for today's
automotive industry, in an environment where every movement, component and every assembly
operation must be immediately and automatically recorded, checked and documented for maximum
efficiency.
Automotive technology has been developed in many areas, like ABS system, active steering
system and other safety systems, which are implemented to increase the passenger safety and
comfort. The development has concluded also the gearbox, which became much smoother and
produces less noise. Gear shifting mechanism must be easy to use and workable, these demands are
very important especially for small cars used by special needs people.
For some drivers, the gear shifting can cause some confusing at driving specially at critical
situations. A crowded road on a hill or a sudden detour makes a lot of tension on the driver. One of
the difficulties in this situation is to choose the right reduction ratio and engaging it at the right time.
