  • Patent number: 8688344
    Abstract: So that kinetic energy of a motor vehicle is recuperated in an optimum way in terms of energy, after a target point for braking or initiation of braking by the motor vehicle driver during travel of the motor vehicle has been detected, an optimum braking distance is determined insofar as the energy which can be recuperated is concerned, and a signal for the vehicle driver is generated which informs the driver the form of the measure which he has to perform in order to brake the vehicle or during braking of the vehicle for braking to actually occur over the optimum braking distance and for kinetic energy to be recuperated in an optimum way. The method combines the calculation of optimum operating states with autonomy of the vehicle driver during braking.

  • Patent number: 8527176
    Abstract: A method and system for measuring pressure in a pressure regulation unit of a motor vehicle braking system, without using pressure sensors and having a motor pump unit with an electric motor and a hydraulic pump. The steps include producing a relative motor characteristic diagram for a series of the units. The diagram includes the data of motor-rotational-speed-dependent parameters, intensity of the motor actuation, and parameters relating to the level of the motor load. Further steps include; determining individual motor characteristic variables, determining a current rotational-speed-dependent parameter of an individual motor during the operation of the pump, and calculating a pressure which is characteristic of the braking system, by means of the diagram parameter of the individual motor and the value of the current motor actuation which determines the intensity of the motor actuation, wherein the individual motor characteristic variables are taken into account.

  • Patent number: 7126458
    Abstract: An alarm system that indicates to an operator the status of locking pins of a vehicle sliding axle assembly. The alarm system includes an alarm valve coupled to the locking pins and in fluid communication with an alarm. When the pins are unlocked from a vehicle component, the alarm valve is configured in an alarm mode to indicate the unsecured condition of the assembly. In this mode, air is diverted from the vehicle brakes to sound the alarm, thereby informing an operator that the pins are improperly engaged. In one embodiment, the alarm valve is in communication with or includes a pressure relief valve, which diverts a sufficient amount of air from the vehicle brakes so that the brakes cannot be released. When the pins are properly locked to secure the slider axle assembly, the alarm valve does not divert air from the brakes to sound the alarm.
