摘要:
In a method for controlling the longitudinal movement of a vehicle (3), in particular by means of a longitudinal movement control system, wherein, for vehicle speeds above a threshold speed, the vehicle speed is adjusted to a higher selected set speed if no vehicle (8) traveling in front is detected, and if a vehicle (8) traveling in front is detected the distance from this vehicle (8) traveling in front is adjusted, below the threshold speed the longitudinal movement of the vehicle (3) is controlled only if a vehicle (8) traveling in front is detected. As a result, an inter-vehicle distance control system can be implemented over a relatively large speed range.

The present invention relates to a method and device for determining a relative velocity between a host (100) and a target (102). The present invention relates in particular to a method of the type that can be used in motor vehicle radar systems and specifically in radar systems of the type that detect obstacles in a blind spot of a motor vehicle. In the method according to the invention the following steps are carried out: substantially simultaneously determining a value for a radial velocity and a bearing with regard to a predefined spatial direction for a large number of measurement points (106) on the target (102); calculating a large number of quotients from the radial velocity and the cosine of the associated bearing, a quotient being calculated for each of the measurement points (106); determining an estimated relative velocity between the host (100) and the target (102) by forming an average of the large number of quotients.
摘要:
In a method and a device for vehicle brake actuation, braking can be actuated as a function of a driver's default value, which can be set by the driver of the vehicle. The default value can be set, in such a way that a braking force dependent on the driver's default value is generated. The braking force actually generated is modified independently of the driver in order to execute an automatic braking sequence when a predefined triggering condition is fulfilled. A limit value for the braking force is determined as a function of the driver's default value, and braking during execution of the automatic braking sequence is actuated independently of the driver in such a way that the modified braking force generated does not quantitatively exceed the limit value determined.

In a method for shortening the stopping distance of a vehicle (2), in which a braking operation is prepared when a predefined event occurs, the braking operation is prepared if a driving situation which is implausible to a driving assistance system occurs. This permits traffic safety to be improved.

There is disclosed a rubber composition comprising: (A) 100 parts by weight of at least one rubber containing olefinic unsaturation; and (B) 1.5 to 50 phr of a silicon coupled oligomer of the formula: where R1 and 2 are individually selected from the group consisting of where R3 is selected from the group consisting of alkyls having 1 or 4 carbon atoms; w is an integer of from 9 to 149, x is an integer of from 1 to 100, y is an integer of from 1 to 100, and z is an integer of from 1 to 100 with the proviso that the sum total of x, y and z in each R1 and R2 ranges from 3 to 100.
摘要:
The device for visibility measurement is designed primarily for use in motor vehicles. A light emitter is arranged inside the driver's compartment preferably on the rear view mirror in front of the windshield. The light emitter generates light pulses or flashes radiating through the windshield. The light scattered back due to soiling on the inside and outside of the windshield or in scatter zones, formed by fog or smoke or the like, in front of the windshield, impinges a light sensor, preferably likewise arranged on the rear view mirror inside the driver's compartment. By utilizing light pulses of various wavelengths and processing of the output signals of the light sensor in predetermined or predeterminable time windows or intervals, not only the respective visibility but also the type of viewing impairment can be determined.
