METHOD AND SYSTEM FOR CONTROLLING A HYBRID VEHICLE

摘要

A method for controlling a hybrid vehicle having an internal combustion engine and an electric machine includes the following steps: (a) sending data indicative of a current location of the hybrid vehicle to a command center after the hybrid vehicle experiences the loss of propulsion; (b) sending data indicative of a desired destination to the command center; (c) receiving a remedial action command from the command center, wherein the remedial action command is based, at least in part, on vehicle operating parameters, the current location of the hybrid vehicle, and the desired destination; and (d) commanding the hybrid vehicle to perform a remedial action corresponding to the remedial action command, wherein the remedial action allows the hybrid vehicle to travel from the current location to a predetermined location after the hybrid vehicle has experienced the loss of propulsion.

1. A method for controlling a hybrid vehicle, the hybrid vehicle including an internal combustion engine, an electric machine, and an energy storage device electrically connected to the electric machine, wherein the method comprises:
sending data, via a control module, indicative of a current location of the hybrid vehicle to a command center after the hybrid vehicle has experienced a loss of propulsion; sending data, via the control module, indicative of a desired destination to the command center; receiving, via the control module, a remedial action command from the command center, wherein the remedial action command is based, at least in part, on vehicle operating parameters, the current location of the hybrid vehicle, and the desired destination, wherein the vehicle operating parameters include a current state of charge (SOC) of the energy storage device; receiving, via the control module, a distance constraint of the hybrid vehicle from the command center, wherein the distance constraint is a range of a distance the hybrid vehicle is capable of traveling from the current location, and the distance constraint is based, at least in part, on the current SOC of the energy storage device; receiving, via the control module, a speed constraint of the hybrid vehicle, wherein the speed constraint is based, at least in part, on the current SOC of the energy storage device; receiving, via the control module, an alternative destination from the command center if the hybrid vehicle is incapable of traveling from the current location to the desired destination; receiving a torque capability of the hybrid vehicle from the command center; determining whether the torque capability allows the hybrid vehicle to drive under the speed constraint and the distance constraint; and commanding, via the control module, the hybrid vehicle to perform a remedial action corresponding to the remedial action command, wherein the remedial action allows the hybrid vehicle to be driven from the current location to a predetermined location after the hybrid vehicle has experienced the loss of propulsion.
