Abstract
A controller for a hybrid vehicle (HV) idles first an internal combustion engine (ICE) when it is determined in advance that a load on the HV or a motor will increase, and thereafter switches to a travelling mode in which the ICE is used. Based on output of a vehicle weight sensor, a gradient sensor, a towing sensor, a start/power mode switch and other on-board sensors or switches, it is determined in advance that a load on the HV or the motor will increase. Otherwise, based on information obtained from a navigation system or from another vehicle to be towed, it is determined in advance that a load on the HV or the motor will increase. Based on a difference of output between an open air temperature sensor and a cabin temperature sensor, a load on an on-board appliance is detected, and based on the detected load, it is determined in advance that a load on the HV or the motor will increase. Thus, a delay in following the ICE in response to the switching of travelling modes can be decreased or remedied.
