At this point should once again be a clear assignment. As long as a hydraulic brake, such as ABS, is not activated by an electronic control system, this is nothing to do with ESP. It does not matter if the system has an electric hydraulic pump. The decisive factor is what is used for ABS, for example, only to return and not to brake operation.

Braking without the driver's intervention will be only since ESP. Obviously, this has inspired the imagination of the technicians, because then there were created several systems, further exploiting the possibilities of active braking. Actually, these have already detached from the topic of ESP, for example in connection with autonomous driving. They are still placed here anyway.

Obviously the learner drivers are not happy anymore, because they are not used to it any other way. They start-up on the mountain road and the brake automatically ensures that the load does not roll backwards. Those who observe the process more closely sometimes have the feeling of slight disagreement. The brake may creak a little and give a slight jerk, because they are more likely to hold on than to release.

Technically worth mentioning to this complex are other wheel sensors, because the previous for ABS react only from a certain wheel speed. In this case it is, for example a Hall sensor with supply voltage whose sensitivity can also be increased by appropriate aperture distribution.

Related to this system is the so-called Hill-Holder, which limits the downhill speed, for example, with SUVs or off-road vehicles, to eg 10 km/h. The name for such systems must be worked out almost at each manufacturer. This also applies to the systems that are particularly safety-relevant in normal driving, such as the brake assist.

It can do a lot, how much, that sometimes depends on the manufacturer. You should not rely entirely on him. What can he do? When things are going very well, he warns of a collision and manages to bring the vehicle to a standstill in time for no response. He is offered as an emergency brake assistant, his sphere of activity can be, so at least the message, limited to the urban area. As I said, by no means rely on it.

Much safer, because many years on the market, is another brake assistant. Its control detects too hesitant pedaling and compensates for this by additional operation. Clever manufacturers mix the capabilities of ESP and its sensors into a system that costs almost nothing besides its development. It prevents rolling over after an accident of certain strength.

And about the now everywhere shown reverse parking with trailer is easily forgotten another danger when driving together, namely that here, for example, in crosswind and oppressive trailer a rolling motion can be set in motion, which also requires a knowledgeable hand to get this back under control.

First of all, it is necessary to recognize such an emergency situation. Then, of course, with specific changes as braked, as would be done with a normal ESP rescue operation. Meanwhile, there is a system with similar effect even only for the trailer.
