Latest Patents

One of his latest patents is a control system for automatic transmission. This system includes a frictional engagement element and an adjusted oil pressure producing mechanism. It is designed to adjust the oil pressure supplied from an oil pressure source to produce an adjusted oil pressure. The hydraulic servo applies or releases the frictional engagement element based on the adjusted oil pressure. Additionally, it features an engine load detecting mechanism and a vehicle speed detecting mechanism. An up-shift deciding mechanism determines whether an up-shift has been executed, while a pressure regulate signal generating mechanism calculates the regulated target pressure of the adjusted oil pressure when the up-shift is executed. The adjusted pressure signal producing mechanism corrects the regulated target pressure based on the difference between the present vehicle speed and the vehicle speed at a shift point when the shift is executed under the current engine load.

Another significant patent involves a method of detecting linear solenoid inter-terminal short of electronic control in an automatic transmission. This method detects a short between terminals of a linear solenoid by sensing when a PWM duty ratio, set by feedback control, is less than a reference duty ratio. The reference duty cycle is calculated to be within a range of expected normal duty ratios in the absence of the short and a range of expected short duty ratios in the presence of the short.
