Eco ACC for Electric and Hybrid Electric Vehicles

Energy optimal Adaptive Cruise Control during following of other vehicles

“…To our knowledge, successful use of DP for this kind of problem has not yet been reported in the literature. In [6], the special case of a preceding vehicle driving at constant speed was addressed by solution of several DP optimization problems. As this is very time consuming we suggest using the A * Algorithm instead which is better suited to meet initial and final constraints simultaneously.…”

“…Assume d is discretized in 1m steps from 20m to 80m, DP would take around four times longer than the A * Algorithm. In [6] about 20 DPs were solved to address a preceding vehicle with constant velocity. Thus, DP would take about 80 times as long as the A * Algorithm and a change of the preceding vehicles velocity would not be permitted.…”

“…In particular, other traffic participants react aggressively and dangerously to ecological driving strategies [8] [9]. No such compromise has to be made when following another vehicle [6].…”

“…Whereas in [6], a single ACC following situation was optimized based on the solution of many Dynamic Programming problems, a concise optimization algorithm suitable to all ACC follow situations is proposed in this paper. Energy optimal drive strategies are derived for two use F. Flehmig is with Robert Bosch GmbH in Abstatt, Germany (phone: +49 7062 911 4597; e-mail: folko.flehmig@de.bosch.com).…”

Advanced co-simulation HMI environment for fully Electric Vehicles

“…EcoACC) by suggesting specific energy-saving actions to driver, therefore increasing driving range [7]. To achieve this, several subsystems including various information sources, sensors and environmental sensing systems are integrated with the objective of providing most useful information to driver to asses an efficient driving profile.…”
