    Abstract: A battery box for a motor vehicle for receiving battery cells has a structural frame with at least two structural components joined to one another at the end face. Each structural component has at least one profile segment that is partially hollow and has a substantially L-shaped cross section. A reinforcement element for absorbing collision energy in the event of a collision is arranged within at least one of the profile segments. The reinforcement element is a molded part having a plurality of open cells, which are arranged adjacent to one another and with their longitudinal extent substantially parallel to one another. When the battery box is mounted in the motor vehicle, the open cells are oriented with their longitudinal extent substantially parallel to the transverse direction of the vehicle.

  • Patent number: 10914385
    Abstract: A method for preparing extruded material for processing to form sealings and/or edge protection strips on vehicle bodies, where the extruded material to be prepared, which is substantially of an elastomer substance, includes a covering strip protecting an adhesive layer and extending in the longitudinal direction of the extruded material. The covering strip has sub-sections that are connected to each other on the abutment ends thereof. The covering strips are detached from the adhesive layer and are reconnected to the adhesive layer, optionally in such a way that they are offset to the longitudinal direction of the extruded material. If the offsetting is carried out, the abutment ends of the sub-sections of the covering strip are arranged such that they are offset in relation to the original position thereof on the adhesive layer.

  • Publication number: 20050146207
    Abstract: A linked brake system for motorcycles includes front and rear wheel brakes, an actuating device by which the front and rear wheel brakes can be operated simultaneously, a control system for controlling brake pressures at the front and rear wheel brakes, and wheel rotational speed sensors for measuring the wheel rotational speeds of the front and rear wheels as well as for determining a reference deceleration approaching the actual vehicle deceleration and for detecting running conditions in which a lock-up tendency exists at at least one of the front wheel and the rear wheel. The wheel rotational speed sensors is connected to the control system. Upon an operation of the actuating device, the control system operates the front and rear wheel brakes with a set brake pressure ratio, provided the reference deceleration is less than a set deceleration.

  • Publication number: 20040181317
    Abstract: The invention relates to a method for determining the mass of a motor vehicle while taking different driving situations into consideration, involving an evaluation of the respective vehicle acceleration, wherein apart from the driving force of a vehicle drive unit the respective resistance forces resulting from rotational forces, from the air resistance, from the rolling resistance and the slope descending force, are taken into consideration and wherein in the same approach additionally the respective braking force is taken into consideration so that a multitude of different driving situations is evaluated, wherein the individual results are stored and combined suitably into a collective mass value. Hereby different driving situations can be weighted differently.

  • Patent number: 6088638
    Abstract: The invention relates to a safety system having electrical consumers (18a, 18b) which are supplied with electrical energy in normal operation from an electrical energy source (2, 4, 6). The safety system includes an electrical energy store (14a, 14b) which supplies the electrical consumers (18a, 18b) with electrical energy when the instantaneous operating voltage at the energy source (2, 4, 6) drops below a limit value. The rated voltage of the energy store (14a, 14b) is less than the rated voltage of the electrical energy source (2, 4, 6) and the electrical energy store (14a, 14b) is connected to the electrical energy source (2, 4, 6) via a switchover element (16a, 16b) which assumes the function of a diode. The switchover element (16a, 16b) ensures that a switchover from normal operation to an emergency operation takes place automatically and that, during normal operation, the electrical energy store (14a, 14b) is not charged unintentionally by the electrical energy source (6).

  • Patent number: 6041276
    Abstract: A device for controlling a starting procedure of a motor vehicle for initiating a movement of the motor vehicle includes a controller which receives as input, signals generated by an engine shaft speed sensor, a driving speed sensor, a transmission shaft speed sensor, a transmission output shaft speed sensor, and an accelerator pedal position sensor. The controller is operatively connected to the engine for increasing the engine speed above a minimum threshold value when the driver signals his desire for a racing start. The controller is also operatively connected to a clutch activation device for deliberately producing a slip of the driving wheels and for controlling the slip of the driving wheels by controlling a slip of the clutch after a starting time point signaled by the driver.

  • Patent number: 5195498
    Abstract: The invention is directed to a method of checking the tightness of a tank-venting apparatus for a motor vehicle having a fuel tank and an internal combustion engine including a lambda controller and an air intake pipe. The tank-venting apparatus includes an adsorption filter, a supply line interconnecting the adsorption filter and the fuel tank, a connecting line interconnecting the adsorption filter and the intake pipe and a tank-venting valve mounted in the connecting line between the adsorption filter and the intake pipe. The method includes the steps of: measuring the pressure difference between pressure in the tank and ambient pressure; when the tank-venting valve is opened, determining whether the pressure difference increases above a threshold value and whether a lean correction by the lambda controller is required; and, drawing the conclusion that the tank-venting apparatus leaks when neither a lean correction is determined nor the pressure difference exceeds the threshold value.
