METHOD AND SYSTEM FOR CONTROLLING A HYBRID VEHICLE

摘要

A method for controlling a hybrid vehicle includes the following steps: (a) monitoring, via a controller, a magnitude and direction of a lateral acceleration, longitudinal acceleration, and longitudinal deceleration of the hybrid vehicle; (b) determining, via the controller, vehicle operating conditions in which a hybrid powertrain is allowed to operate in a regenerative state based, at least in part, on the magnitude and direction of the lateral acceleration, longitudinal acceleration, and longitudinal deceleration of the hybrid vehicle; and (c) commanding, via the controller, the hybrid powertrain to operate in the regenerative state when the hybrid vehicle is operating in the determined vehicle operating conditions. The vehicle operating conditions depend, at least in part, on operator commands and the current SOC of the energy storage system.

1. A method of controlling a hybrid vehicle, the hybrid vehicle including a hybrid powertrain, the hybrid powertrain including an energy storage system, a driveline, an internal combustion engine, and an electric machine electrically connected to the energy storage system, the method comprising:
monitoring, via a controller, a magnitude and direction of lateral acceleration, longitudinal acceleration, and longitudinal deceleration of the hybrid vehicle; determining, via the controller, vehicle operating conditions in which the hybrid powertrain is allowed to operate in a regenerative state based, at least in part, on the magnitude and direction of the lateral acceleration, longitudinal acceleration, and longitudinal deceleration of the hybrid vehicle, wherein, when the hybrid powertrain operates in the regenerative state, torque is transferred from the driveline to the electric machine, the electric machine operates as a generator in order to convert kinetic energy received from the driveline into electric energy, and the electric machine transmits the electric energy to the energy storage system; and commanding, via the controller, the hybrid powertrain to operate in the regenerative state when the hybrid vehicle is operating under the determined vehicle operating conditions.
