Electronic energizer for control element in car etc., e.g. car brake installation, with several control elements at energizing side fed with electric energizing

摘要

Electronic energizer for control elements (9) in car etc. comprises several control elements fed by electric energizing. Energizing of at least one control element is asynchronous in time to at least one other control element, or group of such elements. Preferably control elements are magnetic valves (3,4) of car brake circuit. Energizer is typically of pulse width modulated type and asynchronous energizing may be carried out by firmly preset phase shift of energizing signals, but random generated phase shift may be used. Independent claims is included for method for electronic energizing of control elements.
