Abstract
Aspects of the present invention relate to a control system (100) comprising one or more controllers (105), the control system comprising input means (130) to receive a temperature signal (135) indicative of a temperature of a transmission (160) associated with a traction electric machine (150) of a vehicle, output means (140) to output a control signal (145) for causing a fluidic communication of thermal energy from a heat source to a transmission heat exchanger (190) for heating the transmission, and processing means (110) arranged to control the output means to output the control signal in dependence on the temperature signal.
Claims18
A control system comprising one or more controllers, the control system comprising:
- an input arranged to receive a temperature signal indicative of a temperature of a transmission associated with a traction electric machine of a vehicle;
- an output arranged to operably output a control signal for causing a fluidic communication of thermal energy from a heat source to a transmission heat exchanger for heating the transmission;
- and
- an electronic processing device arranged to control the output to output the control signal in dependence on the temperature signal.
A system for an electric vehicle, comprising:
- a fluid communication system for fluidlicy communicating thermal energy from a heat source to a transmission heat exchanger for heating a transmission associated with a traction inverter and traction electric machine of the vehicle;
- temperature sensing device arranged for outputting a temperature signal indicative of a temperature of at least a portion of the transmission;
- and
- a control system comprising an input arranged to receive the temperature signal, an output arranged to operably output a control signal for causing circulation of the fluid in the fluid communication system, wherein the control system is arranged to output the control signal in dependence on the temperature signal.
A method, comprising:
- determining a temperature of a transmission associated with a traction electric machine of a vehicle;
- and
- causing fluidic communication of thermal energy from a heat source to a transmission heat exchanger for heating the transmission in dependence on the temperature of the transmission.
