Abstract:
System for evaluating the driving environment of a motor vehicle and for influencing the speed of the motor vehicle, with an electronic control unit (ECU) which is connected to a signal transmitter generating a signal characteristic of the desired speed of the motor vehicle, a signal transmitter generating a signal characteristic of the rate of revolutions of the motor vehicle about its vertical axis, a signal transmitter which generates a signal characteristic of objects located in the area in front of the motor vehicle in the direction of travel of the motor vehicle in respect of their distance from and orientation to the motor vehicle, which is the speed relative to the speed of one's own motor vehicle and/or the distance relative to one's own motor vehicle and/or the angle offset or the lateral drift relative to the vehicle longitudinal axis of one's own motor vehicle, and a signal transmitter generating a signal characteristic of the speed of at least one wheel of the motor vehicle and which electronic control unit (ECU) is connected to at least one control device having an influence on the driving behaviour of the motor vehicle, in order to feed to it output signals derived from the driving behaviour of the target motor vehicle located in front of one's own motor vehicle, in which, if a target motor vehicle leaves the detection area in front of one's own motor vehicle, in the electronic control unit a trigger signal is generated which limits the momentary speed or momentarily the acceleration of one's own motor vehicle at least for a stretch to a value substantially corresponding to a maximum of the distance X between one's own motor vehicle and the target motor vehicle at the time of leaving the detection area.

Abstract:
A lane-keep control system is installed in a host vehicle equipped with an inter-vehicle distance control system. The lane-keep control system is arranged to decrease a threshold to be compared with the vehicle traveling condition for determining the tendency of the lane deviation when the inter-vehicle distance is being executed, so that the deviation avoidance control during execution of the inter-vehicle distance control is started earlier than the deviation avoidance control during inexecution of the inter-vehicle distance is started.
Abstract:
A radar detection process includes computing a derivative of an FFT output signal to detect an object within a specified detection zone. In one embodiment, a zero crossing in the second derivative of the FFT output signal indicates the presence of an object. The range of the object is determined as a function of the frequency at which the zero crossing occurs. Also described is a detection table containing indicators of the presence or absence of an object within a respective radar beam and processing cycle. At least two such indicators are combined in order to detect the presence of an object within the detection zone and with changing range gates in each of the antenna beams the coverage of the detection zone can be varied.
Abstract:
In accordance with the present invention, an adaptive cruise control system includes a radio frequency (RF) transmit receive (TR) sensor module (or more simply “sensor”) disposed such that a detection zone is deployed in front of a vehicle. The sensor includes a sensor antenna system which comprises a transmit antenna for emitting or transmitting an RF signal and a receive antenna for receiving portions of the transmitted RF signal which are intercepted by one or more objects within a field of view of the transmit antenna and reflected back toward the receive antenna. With this particular arrangement, a detection system that detects objects in a region about a front of a vehicle is provided. If the system determines that the vehicle is approaching an object or that an object is approaching the vehicle, then the sensor initiates steps that are carried out in accordance with a set of rules that control an accelerator of the vehicle. The accelerator is adjusted to maintain a safe trailing distance behind the detected object.

A preceding-vehicle following control system for a host vehicle is comprised of a road information device (2, 3) for obtaining road information of a road ahead of the host vehicle, a preceding-vehicle detector (1) for obtaining preceding-vehicle information of a preceding vehicle ahead of the host vehicle and a controller (10) connected to the road information device and the preceding vehicle recognizing device. The controller is arranged to determine a road width of the road from the road information, to vary a condition for determining a control characteristic of a control system of a following control for following the preceding vehicle, and to execute the following control on the basis of the condition for determining the control characteristic and the preceding-vehicle information.
