摘要

In electric vehicles electric vacuum pumps are used instead of traditional vacuum generation devices – the vacuum pump or the intake manifold that are specific to vehicles with internal combustion engines. A special driving cycle has to be designed to identify the effectiveness of electric vacuum pumps. The initial experiments were carried out on a real road, intensively applying the breaks and exploiting the vacuum generation devices as long and intensively as possible. Basing on these experiments brake test cycle was developed. It consists of three braking regimes that involve smooth and uninterrupted braking, interrupted and repeated braking and multiple activation of the brake pedal. Using this cycle, it is possible to conduct research on the performance of various automobile components during braking.
