摘要:
Warning braking is carried out in a situation where the warning braking is needed and a crew can recognize the warning braking. If an obstacle is present ahead of the vehicle, and the driver does not carry out brake operation, and the vehicle may collide with the obstacle, the maximum target deceleration Gbt2max for the warning braking is computed. If automatic travel control is not carried out or if automatic travel control is being carried out and its target deceleration Gbt4 is less than a reference value Gbt4s smaller than the maximum target deceleration Gbt2max, the warning braking is carried out. When the target deceleration Gbt4 for the automatic travel control is larger than the allowable reference value Gbt4s for warning braking, the warning braking is not carried out.
摘要:
An object of the present invention is to reliably carry out warning braking in a situation where the warning braking is needed and a crew can recognize the warning braking, and prevent the crew from feeling an unnatural sensation due to the warning braking in a situation where the warning braking is needed but the crew cannot effectively recognize the warning braking. If an obstacle is present ahead of the vehicle, the driver does not carry out brake operation, the driver is looking aside, and the vehicle may collide with the obstacle, the maximum target deceleration Gbt2max for the warning braking is computed. If automatic travel control is not carried out or if automatic travel control is being carried out and its target deceleration Gbt4 is less than a reference value Gbt4s smaller than the maximum target deceleration Gbt2max, the warning braking is carried out. However, when the target deceleration Gbt4 for the automatic travel control is larger than the allowable reference value Gbt4s for warning braking, the warning braking is not carried out.

A drive assist device includes a driver state detection unit that outputs an emergency evacuation start signal, an consent confirmation unit that inquires of the driver, whether or not emergency evacuation control to stop a vehicle at a safe position regardless of a driving operation of the driver is permitted and receives a reply with respect to the inquiry from the driver, and a control unit that performs the emergency evacuation control when the reply which permits the performing of the emergency evacuation control is received from the driver by the consent confirmation unit. The control unit alleviates conditions for performing a preventive drive assist in which the risk for the traveling of the vehicle is avoided during a period from the time of receiving the emergency evacuation start signal to the time of receiving the reply of permitting the performing of the control by the consent confirmation unit.

A trajectory feature point generating unit of a driving support device determines a target speed of a host vehicle when the host vehicle passes the vicinity of an obstacle, on the basis of the maximum possible lateral distance of the host vehicle from the obstacle when the host vehicle passes the vicinity of the obstacle and a map in which a lateral distance and a speed when the host vehicle passes the vicinity of the obstacle are associated with each other. Therefore, for example, the trajectory feature point generating unit can determine the target speed of the host vehicle when the host vehicle passes the vicinity of the obstacle, in the range of the maximum possible distance from the obstacle, such that the speed is equal to or less than a value corresponding to a predetermined distance. As a result, it is possible to determine a state of the host vehicle which is consistent with reality.

A resonance frequency shift amount Δf and a peak level change amount ΔP are measured using a microwave resonator, V1 and V2 are obtained based on V1=(Δf·∈″2/Kf−ΔP·∈′2/Kp)/(∈′1·∈″2−∈″1·∈′2), and V2=(Δf·∈″1/Kf−ΔP·∈′1/Kp)/(∈″1·∈′2−∈′1·∈″2), and an absolute dry basis weight and a moisture amount are obtained based on absolute dry basis weight=β·V1, and moisture amount=γ·V2. For the constants Kf, Kp, ∈′1, ∈′2, ∈″1 and ∈″2, the constants ∈′1, ∈′2, ∈″1 and ∈″2 are determined so that the variance values of Kf and Kp are smaller than a predetermined value.

摘要:
A phase plate is superposed on a sample, and this phase plate is so adjusted that the phase difference of the total retardation of the sample and the phase plate is integral times 2.pi. with respect to a measuring beam of a first wavelength, so that retardation can be correctly measured even if an order is increased. In this state, a measuring beam of a second wavelength which is approximate to the first wavelength is employed and two polarizing plates maintaining polarizing directions in parallel nicol relation are singularly rotated with respect to the sample which is arranged therebetween. The ratio Im/Io between maximum value Io and minimum value Im of currently transmitted light intensity is applied to a previously prepared relation between the order n of retardation and this ratio Im/Io to derive the order of retardation of the sample, to thereafter obtain correct retardation.

An optical lighting system comprising either an optical system or an optical mirror system. In the optical lens and optical mirror systems, the light incident and exiting planes of the lenses and mirrors, are formed to satisfy given equations. Accordingly, in a contact or proximity exposure system, it is possible to unify irradiance on a surface to be irradiated and reduce the optical path length, thus reducing the overall device size. In a projections system, it is possible to unify irradiance on an image surface while efficiently utilizing light by omitting a gradient filter.
