Inventor: BURCKHARDT MANFRED DR ING
IPC: B60T8/00
Filed: 1992-01-03
Abstract: In a braking system with adjustable front-rear axle braking force distribution for a racing vehicle there is an electro-hydraulic braking force control device with an electronic computer stage to take account of the aerodynamic axle-load changes occurring at high speeds which determines an optimised braking force distribution factor from the travelling speed and dynamically detected or assumedly appropriate amounts of the effective adhesion coefficient mu B at the vehicle wheels according to the relation DBom = k1+k2<.> mu B+k3<.>v, where k1, k2 and k3 are vehicle-specific constants obtained from a linear interpolation of the v and  mu B-dependence of the factor DBom, in which it itself is determined in accordance with the relation DBom = Oom/1-Oom for various values of an optimised rear axle braking force component Oom, which in turn is determined on the condition that the locking limit at the front axle should be the same as that at the rear axle. The braking pressure applied to the rear wheel brakes follows that to the front wheel brakes so that the rear axle braking force FBH follows the front axle braking force FBV according to the relation FBH = DBom<.>FBV. This gives optimum vehicle deceleration at a predetermined actuating force.

Title: Method and device for tank ventilation diagnosis in a motor vehicle
Inventor: DENZ HELMUT DIPL ING
IPC: F02D41/00
Filed: 1993-02-11
Abstract: In order to determine whether the tank ventilation system of a motor vehicle is leak-tight, a predetermined vacuum is created therein. The gradient with which this vacuum diminishes when the tank ventilation system is completely closed is then analysed. If the vacuum diminishes more rapidly than is consistent with a predetermined threshold, the system is assessed as leaky. In order to achieve the predetermined vacuum, far more gas must be pumped out of the system when the tank is empty than when the tank is full. In order not to pump out too rapidly and too strongly when the tank is full and in order not to pump for too long when the tank is virtually empty, the duty cycle for opening the tank ventilation valve on the system is varied as a function of the tank filling level so that with the tank virtually full the valve is triggered with a low duty cycle in order to obtain only a low gas rate of flow, whereas with the tank virtually empty a very high duty cycle is selected. <IMAGE>
