A hydraulic brake system for a land vehicle including a hydraulic connection between a master cylinder and wheel brakes that is established or blocked by valve arrangements in dependence upon trigger signals from an electronic control with the electronic control unit devised and programmed in such a way that, in order to set a brake pressure characteristic required for a specific vehicle behavior, the electronic control unit supplies trigger signals through which the setting of a respective brake pressure characteristic in two brake circuits in predefined pressure stages (delta-p) is staggered in terms of time by a substantially predefined time stage (delta-t).

Hydraulic braking system for a land craft

A method for starting a motor vehicle on a downhill route from an idle state includes the steps of maintaining a sufficient brake force to hold the motor vehicle in the idle state, even if brake actuation by the driver is withdrawn; detecting a wish by the driver to drive off; reducing, independently of the driver, the brake force which is maintained independently of the driver, in such a way that the resulting movement of the motor vehicle follows a preset course.

Technique for starting a motor vehicle on a downhill route

A method for starting a motor vehicle, which is held at a standstill on an inclined route by a brake force which is maintained independently of the driver, after a predetermined holding time has elapsed gradually reduces the brake force which is generated independently of the driver, to put the motor vehicle into motion, and then controls the movement of the motor vehicle, corresponding to a preset course.
