Abstract
In a method and a device for controlling the stability of a vehicle, in particular a utility vehicle, an anti-tilt control process is carried out in which at least one lateral acceleration signal, one steering wheel angle signal and one vehicle speed signal are sensed and control signals for vehicle interventions are formed therefrom and output, and a yaw control process is carried out during which the steering wheel angle signal, the lateral acceleration signal and the vehicle speed signal are sensed, a yaw rate setpoint value signal and a yaw rate actual value signal are determined and compared with one another and a yaw control process is carried out during which control signals for vehicle interventions are formed and output.

A method for controlling the stability of a vehicle, comprising, using a control device:
- effecting anti-tilt control including generating control signals to effect vehicle interventions based on the lateral acceleration, steering wheel angle and speed of the vehicle;
- and
- effecting yaw control including determining a yaw rate setpoint value and a yaw rate value estimated based on the lateral acceleration and the vehicle speed, comparing the yaw rate setpoint value and the yaw rate value, and based on the comparison of the yaw rate setpoint value and the yaw rate value, generating control signals to effect vehicle interventions.
A vehicle stability control system, comprising:
- an anti-tilt control system configured to (i) receive a lateral acceleration signal from a lateral acceleration sensor, a steering wheel angle signal from a steering wheel angle sensor and a vehicle speed signal, and (ii) generate control signals to effect vehicle interventions based on the lateral acceleration signal, the steering wheel angle signal and the vehicle speed signal;
- and
- a yaw control system configured to (i) receive the lateral acceleration signal, the steering wheel angle signal and the vehicle speed signal, (ii) determine a yaw rate setpoint value signal and a yaw rate value signal estimated based on the lateral acceleration and the vehicle speed, (iii) compare the yaw rate setpoint value signal and the yaw rate value signal, and (iv) generate control signals to effect vehicle interventions.
