The most highly developed version of the scalable product range - known as ESP® premium.
It is based on a conventional hydraulic braking system, but it can perform all the relevant additional functions of an electro-mechanical braking system without making elaborate and costly changes to the vehicle's electrical system.
By utilising a much more powerful pump, which now has six instead of the previous two pistons, ESP® premium is able to respond very quickly, with the driver barely hearing or sensing anything at all.
It boasts a 90 percent reduction in pressure pulsation compared with the previous ESP models.
The rapid pressure build-up is adjusted to the driving situation and because of the lower noise output, more dynamic interventions are possible to assist the driver, without the system being acoustically intrusive.
In critical situations the speed of pressure accumulation for autonomous, stabilising interventions is increased by a factor of more than 3.
Both the agility of the vehicle and its handling can be improved with this new braking control system.
In addition to the high convenience level in terms of noise and pedal feel, the combination of ESP® premium and "Adaptive Cruise Control" (ACC) allows for significant added functionality.
For example, the active brake control in combination with additional sensors can expand ACC to ACC "Stop & Go".
Using the data from short range sensors, the function automatically applies the brakes in tailgate situations, bringing the vehicle to a complete halt if necessary.
When distance permits, the function can start the vehicle moving forward again without the driver having to do a thing.
In future, the more dynamic pressure accumulation mentioned above will also allow the development of an automatic emergency brake.
ESP® premium thus marks the current state of development in hydraulic braking systems according to the criterion of safety, dynamics, convenience and agility. In addition, it opens up new opportunities for future extensions.
