Motor vehicle e.g. truck,-trailer`s driver assisting method, involves stabilizing backward driving by steering angle controller, and activating and deactivating controller during driving in dependent to steering wheel operation by driver

摘要

The method involves stabilizing the backward driving by a steering angle controller. The controller is activated or deactivated during the backward driving in dependent to the steering wheel operation by a driver. The controller is activated and deactivated, when the driver firmly holds or slowly turns the steering wheel around a small turning angle and when the driver fastly turns the wheel around a large turning angle, respectively. The controller is activated, when the driver turns the steering wheel with a threshold that is smaller than a rotating speed. The steering angle controller is deactivated, when the driver turns the steering wheel with the former threshold or with another threshold that is above the rotating speed.
