Abstract
A controller of a motor vehicle comprises a drive motor, wheels, braking devices for the wheels, said braking devices being separately controllable by the controller, an ambient sensor, a driving status sensor and a steering system. For increasing the driving stability, a steering angle is determinable by the controller from signals of the ambient sensor and of the driving status sensor, said steering angle providing a stable driving status in addition to a targeted braking of the wheels, and the steering angle is adjustable at the steering system in order to keep the motor vehicle on the paved road, in particular when driving along a curve, so that the motor vehicle remains on an intersecting plane of the possible dynamic vehicle area ahead with an actual road without skidding or colliding with other obstacles.
Claims15
A driving system for a motor vehicle including a drive motor, a steering system, wheels, and braking devices for the individual wheels, the driving system comprising:
- an ambient sensor;
- a driving status sensor;
- and
- a controller configured to (a) receive signals from the ambient sensor and the driving status sensor, (b) determine from the signals whether a steering angle (α) provides a stable driving status, and if inconsistencies between acceleration vectors, wheel rotation numbers, vehicle speed and friction coefficients indicate that a stable dynamic vehicle area has been left, calculate a reachable dynamic vehicle area ahead of the vehicle and define an intended area as an intersection of the reachable dynamic vehicle area with an actually existing paved road and (c) adjust, at the steering system, the steering angle (α) and, at the braking devices, targeted braking of the wheels in order to maintain the motor vehicle within the intended area without skidding or colliding with obstacles.
A method of controlling a motor vehicle including a drive motor, a steering system, wheels, braking devices for the individual wheels, an ambient sensor and a driving status sensor, comprising:
- receiving, by a controller, signals from the ambient sensor and the driving status sensor;
- determining, by the controller, from the signals whether a steering angle (α) provides a stable driving status, and if inconsistencies between acceleration vectors, wheel rotation numbers, vehicle speed and friction coefficients indicate that a stable dynamic vehicle area has been left, calculating a reachable dynamic vehicle area ahead of the vehicle and defining an intended area as an intersection of the reachable dynamic vehicle area with an actually existing paved road;
- and
- adjusting, by the controller, (a) the steering angle (α) at the steering system and (b) targeted braking of the wheels at the braking devices in order to maintain the motor vehicle within the intended area without skidding or colliding with obstacles.
