A control unit for a motor-assisted vehicle such as a bicycle is disclosed that effectively provides an assist drive power to a motor-assisted bicycle during a period of initial pedaling or startup on an upward slope or at the time of acceleration. A first...

An electric vehicle (1) comprises a rechargeable secondary battery (30), an electric motor (9) for driving a running section such as wheels, and a controller (5) for conducting control to drive the electric motor (9) by use of the power from the secondary ...

A feedback system 10 and method for use with a hybrid electric vehicle 12 having a propulsion system 14 which includes a motor/generator 16 and an internal combustion engine 20 is disclosed. The system 10 provides a driver of vehicle 12 with tactile, audib...

When feedback control is carried out to ensure that the drive torque of an electric motor(20) for driving each wheel of a vehicle should be equal to a motor torque instruction value, micro-vibration is applied to each tire by superposing a micro-vibration ...

The method involves forming a differential speed value (deltaV) from the actual speed value (Vist) and a predefinable desired speed value (Vsoll). A limited desired acceleration value (asoll) is formed from the differential speed value and a first mass-dep...
