Abstract:
PURPOSE: A network transmission delay minimizing device in a control system and a method thereof are provided to minimize network transmission delay between a sensor and a controller in a sampling shifting method. CONSTITUTION: A sampling shifting unit(40) removes transmission delay generated between a sensor and a controller in a sampling shifting method. A task scheduling unit(50) removes transmission delay between the controller and a driver through a task scheduling method. The sampling shifting unit removes waiting time for transmitting a sample from the sensor to the controller in the sampling shifting method. The sampling shifting unit measures the waiting time generated in a k-1 sampling step. The sampling shifting unit executes a sampling process by controlling the measured waiting time in a k sampling step.

Abstract:
A steer by wire system and a control method using the same are provided to give the least counter force to a steering wheel when a counter force motor is broken while a spring is installed in the steering wheel by employing two control units for each part and motors for an actuator. A steer by wire system comprises a steering wheel(110), three steering wheel angle sensors(120), steering wheel control units(130), a counter force motor (140), and a spring(160). The steering angle sensors are mounted on the steering wheel to detect rotation angle of the steering wheel. The steering wheel control unit compares measured values of each steering angle sensor to detect errors of each steering angle sensor, compares the measured values of the steering angle sensors without errors to calculate difference caused by elasticity of the steering wheels, and measures torque applied to the steering wheel. The counter force motor gives rotation counter force to the steering wheel according to the measured torque value. The spring, which is attached to the steering wheel, provides a minimum counter force to the steering wheel when the counter force motor is out of order. The number of the steering wheel control units is at least two so that one controls the steering wheel when the other is broken.
Abstract:
A vehicle control device is provided to let a disabled person and an old or feeble person drive a vehicle by accelerating, decelerating, braking and steering a vehicle using an electromyogram signal. The vehicle control device comprises an electromyogram signal processing unit(110) obtaining an electromyogram from the body of a driver and processing the obtained electromyogram signal, an A/D(analog to digital) conversion unit(120) converting the processed electromyogram signal into a digital signal, a driver's intention judgment unit(130) receiving the digital signal from the A/D conversion unit and comparing with a standard signal, checking whether the difference value exceeds the critical value set variously by drivers or not and judging the driver's intention of driving a vehicle controller such as a brake system, an accelerator, a steering gear, etc., and then outputting the signal, a control signal conversion unit(140) receiving the signal from the driver's intention judgment unit and converting into a signal for controlling a vehicle controller, a vehicle controller control unit(150) connected with a vehicle controller electrically to drive and control the vehicle controller with the converted signal from the control signal conversion unit, and a vehicle controller driving unit(160) driving the vehicle controller by the vehicle controller control unit.
