The Miser® hydraulic-hybrid transmission has been tested and proven at the Gerotek Test Facility. This paper presents the initial results of test runs of the first version of Miser®. The technology was developed for a heavy-duty truck as an engine-optimising and regenerative-braking transmission that can be retrofitted to most heavy trucks. It uses a novel hydraulic pump/motor system to harvest and store brake energy in accumulators. The paper highlights the savings achieved from a set of drive cycles during the first tests. An extract of some of the results achieved on the test track is presented to show what the test vehicle achieved.
