Sensor system for dynamic control of vehicle - has pair of sensors straddling each axis and with central processor

Номер: DE0004201146A1
Принадлежит:

Pairs of sensors are mounted each side of each of the three axes through the centre of gravity of the vehicle. The sensor outputs are collected by a central processing unit and the rotational and linear movements about and along each axis are computed. This enables the vehicle dynamics to be controllled, e.g. steering, active suspensions etc. The sensor pairs are directed in opposite ways and thus together provide the required information for each axis. The system can compute the dynamic condition for any selected point of the vehicle to enable, e.g. the separate suspension elements to be controlled. USE/ADVANTAGE - Predicting behaviour of motor vehicle. Centrallised control; min. of sensors; active dynamic control.

Method for controlling speed of motor vehicle prior to vehicle traveling around bend involves controlling speed in dependence of target speed determined by iterative process

Номер: DE0019848236A1

The method involves determining a target speed (Vsoll) before the vehicle reaches the curve by an iterative process in dependence on the vehicle actual speed (VFZ), the maximum transverse acceleration (aymax) and curve radius (R) of the bend determined using a navigation system and GPS receiver. The target speed approaches a limit speed at which the curve can be travelled through safely. The speed of the vehicle is controlled in dependence on the target speed and the actual speed, with the speed being reduced by a reduction in drive torque or an increase in braking torque.

Torque distribution control in a vehicle

Номер: GB0002323454A
Принадлежит:

A four-wheel drive vehicle is controlled to improve the steering and road holding of a vehicle in a marginal condition when at least some of the vehicle wheels begin to slip during a turn. To achieve this the vehicle has a yaw rate sensor 17, a lateral acceleration sensor 18, a steering angle sensor 16 and a vehicle speed sensor 15 signals from the sensors are delivered to a control unit 20 where the yaw rate and lateral acceleration are calculated and the difference between the calculated rates and the sensed rates is used to select values of front and rear wheel cornering power (Kf,Kr). Using the steering angle and the vehicle speed a target angular velocity is calculated using calculating means 21. Together with the cornering powers a target directional angular velocity is calculated using means 24. From the directional angular velocity and the target directional angular velocity is calculated a correction coefficient (Ke) which is used to control a torque distribution means.

A method in which first and second sensor data is received 1904 from first and second sensors of a vehicle, the first sensor data representing operation of the vehicle in accordance with a first trajectory and the second sensor data representing at least one object. It is determined 1908 that the first trajectory violates a first behavioural rule of operation based on the first sensor data and the second sensor data. The first behavioural rule has a first priority. Multiple alternative trajectories are generated 1912 using control barrier functions. A second trajectory is identified 1916 that violates a second behavioural rule having a second priority less than the first priority. Responsive to identifying the second trajectory, a message is transmitted 1920 to a control circuit of the vehicle to operate the vehicle based on the second trajectory.

In a torque splitting device for distributing an input torque applied to an input member to a pair of output members adapted to be coupled with right and left driven wheels of a vehicle at an adjustable distribution ratio, the distribution ratio is determined in such a way that the understeer and oversteer tendencies of the vehicle under a positive or negative drive condition while turning a curve is appropriately controlled. In particular, it is highly desirable to prevent an understeer tendency from appearing while turning a curve. Therefore, when the vehicle is under a positive drive condition while tuning a curve, a yaw moment is produced by an appropriate torque distribution which assists the vehicle to turn in such a way that the understeerg condition is canceled. Furthermore, when the vehicle moves on from a positively drive condition to a negative drive condition while turning a curve, a slight oversteer tendency is produced with a minimum time delay so as to avoid any transient ...

A control module for a vehicle system has: a lateral acceleration sensor for measuring a lateral acceleration and outputting a lateral acceleration measurement signal, a yaw rate sensor for detecting a yaw rate and outputting a yaw rate measurement signal, and a central control device for receiving the yaw rate measurement signal and the lateral acceleration measurement signal and determining a lateral acceleration of the vehicle at its center-of-gravity. The central control device determines the center-of-gravity lateral acceleration from a sensor distance of the lateral acceleration sensor from the vehicle center-of-gravity and the yaw rate measurement signal, forming a derivative over time. The central control device filters the yaw rate measurement signal with a low-pass filter and subsequently forms a derivative over time and determines the sensor distance on an up-to-date basis.

System and method for preventing vehicle from rolling over in curved lane

Номер: US20140081542A1
Принадлежит: Automotive Research and Testing Center

The present invention proposes a system and method for preventing a vehicle from rolling over in curved lane. The road images captured by the image capture devices are used to calculate road information. The road information together with the vehicular dynamic information, such as the speed and acceleration of the vehicle are used to predict the rollover angle and lateral acceleration of the vehicle moving on the curved lane. The height of the gravity center and critical rollover speed of the vehicle moving on the curved lane are worked out and used to define a vehicular rollover index. If the vehicular rollover index exceeds a preset value, the system warns the driver or directly controls the speed of the vehicle to prevent the vehicle from rolling over in the curved lane.

Travel control apparatus for vehicle

Номер: US20160132055A1
Принадлежит: Fuji Jukogyo KK

In a travel control apparatus for a vehicle, a travel environment information acquisition unit acquires travel environment information on a travel environment of the vehicle. A travel information detector detects travel information on the vehicle in order to execute automatic driving control based on such information pieces. A lateral force generator generates lateral force to be applied to the vehicle during the automatic driving control. A torsion bar is interposed on a torque transmission path of a steering system. A steering wheel angle detector detects a steering wheel angle. A lateral force detector detects the lateral force acting on the vehicle. An intervening steering operation determination unit determines that a driver has performed an intervening steering operation when a characteristic of the detected steering wheel angle and lateral force differs from a reference characteristic that varies univocally when the steering wheel is in a no load condition.
