Technology
A research team led
by Associate Professor Hiroshi Fujimoto of Tokyo University and Mitsubishi Motors jointly developed the electric vehicle control technology that enables a
driver to drive his car without changing his driving sensation even he is
traveling on the slippery road. It adjusts the driving power both of the front
and rear wheels to maintain the total driving power. It will supposedly become
a predominant technology in the future. It can be applied to a 4x4 electric
vehicle loaded with an in-car motor and differential gears to make it even more
fun-to-drive.
On the slippery road, the technology gives the
preview control that the front wheels tell the rear wheels how many seconds
later they get to the slippery point and adjusts the total driving power
depending on the anticipated slip. Based on the drive test, the research team
found that the gravity applied to the body decreased from 5% of the standard
electric vehicle to 2.5%. The rocking vibration the drive feels when he
accelerates or decelerates his car can be decreased without a decrease of
torque. The research team wishes to establish the control technology for more
comfortable travel by solving problems with the control on acceleration and
turning.
