Title: Device and method for steering of car
Inventor: BURAIAN KEI BUOON
IPC: B62D7/15
Filed: 1990-06-22
Abstract: PURPOSE: To prevent the occurrence of an unexpected running state by switching from one steering mode to another steering mode according to a selected steering mode only when it is sensed that rear steering wheels are within a prescribed angle in the straight advancing direction. CONSTITUTION: A control means 64 inputs signals from a front steering angle sensor 32, a vehicle speed sensor 68, an engine speed sensor 70, a lock engagement sensor 62, and a rear steering angle sensor 56 and determines the steering angles of rear wheels 42 and 44 according to a steering mode, selected by a selection switch 66, for example, a front steering angle, and performs assist steering. In which case, when some steering mode is selected by a mode selection switch 66, the control means 64 effects variation from a present steering mode to a selected steering mode only when a rear steering angle detected by a sensor 56 is within a prescribed angle in the straight advancing direction. This constitution prevents the occurrence of an unexpected running state due to variation of a steering mode during high speed running.

Abstract: PURPOSE:To regulate the frequency of driving voltage to follow up the resonance frequency of stator by providing a driving circuit for applying a driving voltage having predetermined frequency onto an oscillator with predetermined phase pattern, an induced voltage comparing circuit, a drive detection/switching circuit, and a frequency tracking circuit. CONSTITUTION:A control circuit 103 receives an oscillation signal from an oscillation circuit 105 having oscillation frequency same as the resonance frequency of an oscillator 107 and a signal from a phase inverting circuit 106 and outputs a control signal. A driver 104 amplifies a drive control signal fed from the control circuit 103 and applies a driving voltage onto the oscillator 107. A drive detection/switching circuit 109 performs switching between application of driving voltage onto an oscillator 108 and detection of voltage induced in the oscillator 108 and then the induced voltage is compared with a predetermined reference voltage through an induced voltage comparing circuit 113. A frequency tracking circuit 114 then controls the oscillation frequency of the frequency tracking circuit 114 based on the comparison results. Since the induced voltage increases under resonant state, oscillation frequency, i.e., the frequency of the driving voltage, is regulated to maximize the induced voltage.
