  • Patent number: 8290675
    Abstract: In a method for recovering energy in a braking process of a hybrid vehicle which has an internal combustion engine and an electric drive, as well as a hydraulic or pneumatic braking system, the exploitation of the electric drive is able to be optimized if the braking system includes at least one pressure reduction valve, using which the braking pressure exerted by the driver is able to be reduced as a function of the deceleration proportion of the electric machine.
    Type: Grant
    Filed: July 6, 2006
    Date of Patent: October 16, 2012

  • Patent number: 6510527
    Abstract: A method and a system for data protection of fixed and learned control data of duplicated, program-controlled computers, in which the control parameters are stored in an EEPROM. The memory available in the EEPROM is divided into three areas. Each area is monitored using a check sum (check sum 1, check sum 2, check sum 3) that is stored therein. Only the self-learned variables are maintained redundantly. Thus, the ability to store more data than previously in the EEPROM with the same data protection and the same accessibility is provided, thus allowing more flexible solutions with respect to varying customer requirements to be offered.
