A controller 140 operates a powertrain of a hybrid vehicle 100 so as to avoid one or more undesirable combinations of values of generator 123 torque load, driveline speed parameter and driveline ratio parameter. The driveline speed corresponds to a speed Wtx of an output portion 124S of a transmission 124 and the driveline ratio parameter corresponds to a gear ratio TG selected in the transmission 124. Controller 123 uses Wtx and TG in a look-up table to produce an upper limit of allowable CIMG 123 charging torque TQ(maxcharge). If CIMG 123 torque exceeds TQ(maxcharge) the controller 140 commands the CIMG 123 to deliver a value of torque corresponding to TQ(maxcharge). In some embodiments the controller 140 is configured to force the transmission 124 to change gear whenever a value of CIMG 123 torque exceeds or is at risk of exceeding TQ(maxcharge). Reference is also made to a method of controlling a hybrid vehicle and to a hybrid vehicle. |
