Changing to a lower gear ratio in an automatic transmission is controlled by an electronic system. This calculates a torque ramp from a transducer output to decide when the change must be made. A transducer produces a signal which is a function of the output torque of a drive shaft for an...
A method, system, and computer readable medium are disclosed for controlling the change of ratio in an automatic gear box during a transition from a first engine operating mode to a second engine operating mode. The method comprises determining the current 200 and next 202 engine operating modes...
摘要: PROBLEM TO BE SOLVED: To provide a method that enables a vehicle to start safely even if a stroke sensor goes wrong, which detects a position of a shift and select lever that switches a gear changeover of an automatic gear transmission....
gearshift level (GSest), it is determined that the gearshift level of the automatic transmission is abnormal (S130, S140), whereas when the cause thereof is due to modification of the minimum permissible gearshift level (GSmin), the fact that the estimated gearshift level (GSest) is ...
System and method of controlling automatic transmission A shift control system for an automatic transmission wherein shifting from a first gear ratio to a second gear ratio is carried out by releasing the hydraulic pressure of a first friction engaging element for disengagement thereof and su...

Also known as first gear, this mode in automatic transmission slows down the engine and provides more torque. In an auto car, the gears automatically shift from ‘park’ or ‘idle’ to first and then gradually up to the fifth depending on the speed of the vehicle. ...
PURPOSE: An automatic transmission installed with a torque converter and an automatic shift method using the transmission are provided to improve traveling performance and to reduce the output loss of an engine by increasing torque load of a pump connection drive shaft and reducing a slip of the ...
First, you can notice that the transmission shifts into the first and then to second gear but does not move into the third gear. It seems that the gear slips into neutral when you push it to the third. Another instance could be theautomatic transmission won’t shift into 3rd gearat all...
