Patent number: 5260877Abstract: A method and an arrangement for electronically controlling an internal combustion engine of a motor vehicle.

Patent number: 5101115Abstract: In an evaluation process for output signals of an acceleration-sensitive sensor in restraint systems for vehicle occupants, the output signals of the sensor are picked up and evaluated periodically. In a normal, uncritical operating state the evaluation occurs after relatively long intervals of time. If indications suggest a critical operating state, that is, an accident, however the evaluation of the output signals of the sensor occurs at shorter intervals of time.Type: GrantFiled: September 19, 1989Date of Patent: March 31, 1992Assignee: Robert Bosch GmbHInventors: Werner Nitschke, Wolfgang Drobny, Hugo Weller, Peter Taufer

Patent number: 5068640Abstract: A safety device for vehicle occupants has an operational voltage source, typically the vehicle's battery, and a storage device for electrical energy, typically a capacitor. Several tripping devices, typically ignition tablets, are coupled to the storage device and/or the operational voltage source, for actuating inertial restraining devices, such as airbags, belt tighteners or the like. If the storage device fails, each tripping device is connected for a specified period of time to the operational voltage source by a respective switch. Each switch is triggered by an evaluating device. Therefore, if the storage device fails, as long as the operational voltage source is connected to the safety device, each tripping device and, therefore, inertial restraining device can be actuated.Type: GrantFiled: April 4, 1990Date of Patent: November 26, 1991Assignee: Robert Bosch GmbHInventors: Wilfried Burger, Werner Nitschke, Peter Taufer, Hugo Weller

Patent number: 5058920Abstract: A method of actuating a safety device for vehicle occupants, wherein the safety device has several tripping devices coupled to a capacitor and to passenger restraint devices, such as air bags, seat belts, or the like. The energy supplied by the capacitor to a tripping device is measured upon actuation of that device. If the energy supplied exceeds a predetermined limit, the flow of electric current from the capacitor to the respective tripping device is interrupted. Thus, if an actuated tripping device shunts, the energy of the capacitor is not drained by the shunt, and the capacitor maintains an energy level sufficient to actuate the other tripping devices.Type: GrantFiled: March 1, 1990Date of Patent: October 22, 1991Assignee: Robert Bosch GmbHInventors: Wilfried Burger, Werner Nitschke, Peter Taufer, Hugo Weller

Patent number: 5023468Abstract: A safety device for a vehicle occupant comprising a restraint for the vehicle occupant, a sensing circuit for evaluating a vehicle condition, a control circuit for actuating the restraint in response to a predetermined vehicle condition, and two separate reserve energy storages for supplying electrical energy to the sensing and control circuits, respectively.Type: GrantFiled: January 25, 1989Date of Patent: June 11, 1991Assignee: Robert Bosch GmbHInventors: Wolfgang Drobny, Werner Nitschke, Peter Taufer, Hugo Weller

Patent number: 5014810Abstract: In a method for controlling the release of a passenger restraint system in a vehicle, an acceleration signal is measured and integrated with respect to time to obtain a velocity signal. A release threshold value for the velocity signal is determined. If the velocity signal then falls below the release threshold value, thus indicating a vehicle collision, the passenger restraint system is released. The release threshold value is controlled depending on the type of accident situation and upon the operating parameters of the vehicle to increase the release sensitivity of the passenger restraint system. For example, the release threshold value is adjusted based on the value of the velocity signal. If the velocity signal decreases in value, then the release threshold is lowered to a more sensitive value.Type: GrantFiled: December 28, 1989Date of Patent: May 14, 1991Assignee: Robert Bosch GmbHInventors: Bernhard Mattes, Werner Nitschke, Willi Kuhn, Wolfgang Drobny, Hugo Weller, Peter Taufer, Edmund Jeenicke, Klaus Reischle, Michael Henne, Wilfried Burger

Patent number: 5015870Abstract: A voltage supply circuit has an energy reserve, which is charged by a voltage transformer, and a comparator circuit, which controls switching circuit components. When the supply voltage is at its nominal value, a first switching circuit component is closed, with the result, that the energy reserve is operated in open circuit and is charged by the voltage transformer. When the supply voltage drops below a threshold, the comparator circuit opens the first switching circuit component and closes a second switching circuit component with the result that, at this point, the charged energy reserve is available for the voltage supply to the circuit configuration normally supplied with voltage from the supply voltage and the voltage transformer is disconnected from the supply voltage.Type: GrantFiled: August 3, 1989Date of Patent: May 14, 1991Assignee: Robert Bosch GmbHInventors: Wolfgang Drobny, Bernhard Mattes, Werner Nitschke, Peter Taufer, Hugo Weller
