Abstract:
A video amplifier for a radar receiver includes a temperature compensating attenuator. The attenuator includes a temperature sensitive device, such as a thermistor, arranged in a voltage divider network and is coupled in cascade between two filter stages. Each of the filter stages has a bandpass characteristic in order to filter low-frequency leakage signals and provide sensitivity control based on frequency and thus range, while also filtering high frequency signals to reduce aliasing.
Abstract:
The invention relates to a device and a method used to monitor misadjustments of the distance sensor of a motor vehicle, combining two individual methods. Both individual methods are selected in such a way that one method has advantages in areas where the other method functions at a disadvantage, whereby the shortcomings of one method can be compensated by the strengths of the other. By combining said methods, it is possible to decide with a far greater degree of reliability whether a misadjustment has occurred, requiring suitable follow-up measures or whether an extreme misadjustment has occurred, requiring the shut-down of the system.
Abstract:
System for evaluating the traffic environment of a motor vehicle and for influencing the speed of the motor vehicle in its own traffic lane, comprising an electronic control unit (ECU), which is connected to a signal transmitter that produces a signal characteristic of the desired speed of the motor vehicle, a signal transmitter that produces a signal characteristic of the yaw of the motor vehicle about its vertical axis, a signal transmitter that produces a signal characteristic of the articles situated, in the direction of travel of the motor vehicle, in front of the motor vehicle in terms of their spacing and orientation relative to the motor vehicle and which reproduces the speed relative to the speed of the system motor vehicle and/or the spacing relative to the system motor vehicle and/or the angular offset or the cross track distance relative to the vehicle longitudinal axis of the system motor vehicle, and a signal transmitter that produces a signal characteristic of the speed of at least one wheel of the motor vehicle, and which is connected to at least one control device, which influences the performance of the motor vehicle, in order to supply said device with output signals derived from the performance of the motor vehicle situated in front of the system motor vehicle, in which in the electronic control unit (ECU) the width of the system motor vehicle traffic lane is modified in dependence upon the distance of articles detected in the space in front of the system motor vehicle from the system motor vehicle, wherein the width in the close range and in the remote range is smaller than in the medium range.
Abstract:
An automotive lane deviation prevention (LDP) apparatus includes a control unit detecting whether a host vehicle is in a specific state where the host vehicle is traveling on road-surface irregularities formed on or close to a lane marking line. The control unit actively decelerates the host vehicle when the host vehicle is in the specific state where the host vehicle is traveling on the road-surface irregularities.
Abstract:
When a vehicle travels along a curve of a road, a target vehicle acceleration/deceleration that is used for accelerating/decelerating the vehicle to a target vehicle speed, which is set for the curve, is calculated. Based on a comparison between a present vehicle speed of the vehicle and the target vehicle speed, the vehicle is controlled such that an acceleration/deceleration of the vehicle coincides with the target vehicle acceleration/deceleration.
Abstract:
A lane deviation avoidance system for an adaptive cruise control system equipped vehicle includes an electronic control unit that executes a host vehicle's lane deviation avoidance control in which a change in vehicle dynamic behavior occurs in a direction that avoids the host vehicle from deviating from a driving lane when there is a possibility of the host vehicle's lane deviation from the driving lane. The control unit puts a priority on the lane deviation avoidance control by limiting a driving force acting on the host vehicle, when there is the possibility of the host vehicle's lane deviation from the driving lane.
Abstract:
In an automotive lane deviation avoidance system that prevents a host vehicle from deviating from its driving lane by correcting the host vehicle's course in a direction that avoids the host vehicle's lane deviation in the presence of a possibility of the host vehicle's lane deviation, the system calculates a desired yawing moment needed to avoid the host vehicle's lane deviation from the driving lane. The system compensates for the desired yawing moment by a correction factor or a gain, which is determined based on a throttle opening of the host vehicle.
