Method for securing a vehicle on a roller dynamometer

A method for securing a vehicle, whose wheels of one axle are on a dynamometer, against being unintentionally pushed out of the dynamometer during an inspection of the parking brake. In order to avoid endangerment of people who are in the surroundings of the vehicle, it is proposed to ascertain with the aid of a sensor system whether the vehicle is located on a dynamometer and, if this has been determined, to automatically generate a braking torque at a wheel brake of at least one wheel, which is located outside the dynamometer, after a control element of the parking brake has been operated.

Vehicle Brake Health Monitoring
20200276965 · 2020-09-03 ·

There is disclosed a method and system for vehicle brake management. A vehicle brake test is performed in order to output a measure of brake performance under one or more test condition. The measure of brake performance is used to generate a value of current vehicle brake effectiveness for a predetermined usage condition. A mathematical model is applied to said value of current vehicle brake effectiveness so as to predict a decline in braking effectiveness with vehicle usage. The mathematical model is used to determine a point at which said predicted decline crosses a threshold value of vehicle brake effectiveness and an indication of the extent of vehicle usage corresponding to said crossing point is output. The method and system may be used to monitor brake performance compliance with regulations and/or to generate brake test/maintenance schedules.
