A Novel Gearshift Control Method based on Historical Driving Information

This paper proposes a logical control approach for the gearshift strategy design aimed to improve the fuel consumption efficiency of the commuting vehicle such as city bus or trucks. The vehicle dynamics is discretized with respect to the route segment, and then it is further modeled as the stochastic logical dynamical system in view of the probability characteristic of the driver acceleration demand at the specific route segment. The fuel consumption optimization problem is constructed as a finite horizon optimal control problem under the framework of the proposed stochastic logical dynamical systems. Then the optimal gearshift strategy is obtained by applying a logical dynamic programming algorithm. Simulation results demonstrate the potential fuel-saving performance of the proposed control scheme.
