Abstract
Aspects of the present invention relate to a control system and method for controlling a state of charge of energy storage means of a hybrid electric vehicle, the control system comprising one or more electronic controllers, the one or more electronic controllers configured to: receive destination data; determine a route to be travelled by the vehicle, the route comprising one or more characteristics, in dependence on the received destination data; and control the state of charge of the energy storage means in dependence on the route to allow the vehicle to travel an end portion of the route in an electric-only mode.
Claims14
A control system for controlling a state of charge of energy storage means of a hybrid electric vehicle, the control system comprising one or more electronic controllers, the one or more electronic controllers configured to:
- receive destination data;
- determine a route to be travelled by the vehicle, the route comprising one or more characteristics, in dependence on the received destination data;
- control the hybrid electric vehicle to maintain a charge sustain threshold, wherein the charge sustain threshold is a value at which the energy storage means is not permitted to fall below;
- and
- control the state of charge of the energy storage means in dependence on the route to allow the vehicle to travel an end portion of the route in an electric-only mode;
- wherein controlling the state of charge of the energy storage means comprises controlling an electrical energy storage of the vehicle;
- wherein controlling the electrical energy storage of the vehicle comprises allowing the state of charge of the energy storage means of the vehicle to fall below the charge sustain threshold of the vehicle to allow the vehicle to travel the end portion of the route in electric-only mode;
- and
- wherein controlling electrical energy storage of the vehicle comprises allowing the state of charge of the energy storage means of the vehicle to fall below the charge sustain threshold in dependence on the availability of at least one vehicle charger at the end of the route.
A method for controlling a state of charge of energy storage means of a hybrid electric vehicle, the method comprising:
- receiving destination data;
- determining a route to be travelled by the vehicle, the route comprising one or more characteristics, in dependence on the received destination data;
- controlling the hybrid electric vehicle to maintain a charge sustain threshold, wherein the charge sustain threshold is a value at which the energy storage means is not permitted to fall below;
- and
- controlling the state of charge of the energy storage means in dependence on the route to allow the vehicle to travel an end portion of the route in an electric only mode;
- wherein controlling the state of charge of the energy storage means comprises controlling an electrical energy storage of the vehicle;
- wherein controlling the electrical energy storage of the vehicle comprises allowing the state of charge of the energy storage means of the vehicle to fall below the charge sustain threshold of the vehicle to allow the vehicle to travel the end portion of the route in electric-only mode;
- and
- wherein controlling electrical energy storage of the vehicle comprises allowing the state of charge of the energy storage means of the vehicle to fall below the charge sustain threshold in dependence on the availability of at least one vehicle charger at the end of the route.
