摘要： A failsafe steering device for a steer-by-wire system includes a main Electronic Control Unit (ECU) that detects manipulating states of a main steering wheel and a rack mechanism via a plurality of sensors, actuates a reaction motor that provides the reaction force to the main steering wheel in relation to a driver's steering force, and controls a steering motor that executes the steering by actuating the rack mechanism. The failsafe steering device further includes a battery providing power to the steering motor, a relay restraining the power supply between the battery and the steering motor, a failsafe ECU that determines the malfunction state of the main ECU and controls the relay accordingly, and a steering shaft that transmits the rotational force of a supplement steering wheel to the rack mechanism.

摘要： The present invention relates to a control system of an auxiliary power system for a hybrid electric vehicle in which a circuit of the control system of the auxiliary power system is constructed by a digital method. The control system has a function for monitoring a battery charging state and a function for controlling an engine at a constant speed. The auxiliary power system for a hybrid electric vehicle includes an engine, a generator, a battery, and a load. The control system includes a rectifier, a first shunt circuit, a smoothing circuit, a contactor, a main control circuit portion, an engine constant-speed control portion, an auxiliary battery, DC/DC converter, a battery charge voltage monitoring portion, a control state display portion, and a second shunt circuit. The engine constant-speed control portion controls the engine at a constant speed by detecting an engine throttle position signal and an engine rpm signal, and controls the engine rpm and the engine on/off by a signal communication between itself and the main control circuit.
