METHOD AND SYSTEM FOR OPTIMISATION OF ENERGY CONSUMPTION IN VEHICLE Russian patent published in 2018 - IPC B61L3/00 B60K31/00 G06F17/00 G01C21/34 B60T8/32 

FIELD: transportation.

SUBSTANCE: vehicle energy consumption optimisation system includes a route calculation device and a speed profile generator. The route calculation device combines the path sections into one route from the initial point to the destination. The speed profile generator, located partly outside the vehicle, uses the vehicle energy consumption model together with the road gradient data corresponding to the specified route to calculate the optimum speed profile. The generator is configured to determine the values of the speed at which the passage of the corresponding sections of the route will occur with the optimum level of energy consumption. To determine the optimum speed profile, the speed profile generator is configured to compare the energy consumption for a plurality of possible speed profile trajectories between the maximum and minimum trajectories. Also, the system comprises a device for adjusting the speed based on the current position of the vehicle and the optimum speed profile.

EFFECT: increase energy consumption efficiency.
