20220281523 · 2022-09-08 ·

Apparatus for controlling dynamics of a vehicle determines a current course angle (α) of the vehicle. A desired course angle (α.sub.psi) is defined and assigned to a first point on a temporal profile of a desired driving line. The first point is on the desired driving line at a first preview time from a location assigned to an instantaneous vehicle position. A course angle deviation of the current course angle (α) from the desired course angle (α.sub.psi) is determined. A target angle (α.sub.ta) is defined and assigned to a second point on the temporal profile of the desired driving line. The second point is on the desired driving line at a distance of a second preview time from the location. A steering wheel angle (δ) is determined as a total of the target angle (α.sub.ta) reinforced with a first parameter and the course angle deviation reinforced with a second parameter.

20210309192 · 2021-10-07 ·

A steering control system for a commercial vehicle having a braking system to brake dissymetrically side wheels. The steering control system, including a sensor unit and a control module, is configured to detect a braking request or deceleration of the vehicle and/or to detect a lateral offset and to generate a brake indication signal and/or steering demand. The control module is configured to receive the brake indication signal and/or steering demand. If the steering demand is below a predetermined threshold value, the control module is configured to generate the steering signal only if the brake indication signal indicates a braking request. If the steering demand exceeds the predetermined threshold value, the control module is configured to generate the steering signal even if the brake indication signal indicates no braking request. The control module provides the steering signal to the braking system to brake the vehicle dissymetrically to steer the vehicle.

The invention elates to a method for operating a transversal guidance system of a motor vehicle through two independent channels to perform automatic transversal guidance interventions. Through the first channel, transversal interventions are performed via a first transversal guidance actuator controlled by means of a driver-operated steering handle. Through the second channel, a vehicle system sets a target, roll angle, and a second transversal guidance actuator is controlled by a transversal guidance system that performs a transversal guidance intervention based on the roll angle. The vehicle system displays the roll angle as a notification to the driver of the transversal guidance intervention. The invention also relates to a motor vehicle configured to perform the method.
