Title: Zensaku Murakami: Innovator in Vehicle Control Technologies
Introduction
Zensaku Murakami is a notable inventor based in Susono, Japan, recognized for his contributions to vehicle control technologies. With a total of six patents to his name, Murakami has made significant advancements in the field of automotive engineering.
Latest Patents
One of his latest inventions is a traction control apparatus for vehicles. This apparatus sets an allowable slip ratio to a constant value that is relatively high when the shift position of a sub-transmission is in 'H'. Conversely, when the shift position is in 'L' and the difference between the maximum and minimum wheel speeds is less than a threshold value, the apparatus adjusts the allowable slip ratio to a smaller constant value. If the slip ratio of any driving wheel exceeds this allowable limit, the system applies a predetermined braking force to maintain control. Another significant patent is a vehicle-behavior control apparatus and method. This system includes a control unit connected to the braking system and vehicle status sensors. It directs the braking system to distribute appropriate braking force to each wheel based on the vehicle's spin or drift moment, as determined by sensor outputs.
