Title: Electric power steering system
Inventor: NISHIMOTO MITSUHIKO
IPC: B62D6/00
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To detect the grounding of a motor terminal or failures in a motor- current detector circuit in a shorter decision period of time without providing any motor-current detector circuit for detecting failures. SOLUTION: A power steering system determines a target value of motor currents of a steering-force assist motor on the basis of the detected value of the steering torque of a steering wheel and rotates the motor so that the motor current reaches the target value to thereby assist the steering force.  The power steering system comprises a steering-speed detection means S28, a steering-speed comparison means S30 for comparing the detected value by the steering-speed detection means S28 with a predetermined value, a motor- current comparison means S14 for comparing the difference between the target value and the motor current with a predetermined value, and an abnormality- occurrence detection means S32 for determining the occurrence of abnormality if the detected value is found smaller in the comparison by the steering-speed comparison means S30 as well as if the difference is found larger in the comparison by the motor-current comparison means S14.

IPC: B60L50/30
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To reduce charging time by rotating and driving a flywheel using a commercial power supply and charging a secondary battery due to a rotary energy being supplied from a flywheel device. SOLUTION: A flywheel 6 that is mechanically coupled to a rotary shaft due to the rotary drive of an electric generator 8, and an AC electrical energy from a commercial power supply is accumulated as a rotary mechanical energy. When the flywheel 6 reaches a specific high-speed rotary state via a CPU 14, a charge control means 10 sends out a control signal for giving a rotary magnetic field at a slower speed than the rotary speed of a rotor part to the stator part of the electric generator 8 for an inverter circuit 11, and drives the electric generator 8 as a generator by the rotary mechanical energy which was accumulated in the fly wheel 6. The inverter circuit 11 converts AC electrical energy being generated by the electric generator 8 into to a DC electrical energy according to the control of the CPU 14 and accumulates it in a secondary battery 2 via a distribution circuit 15.
