摘要： Embodiments of the present invention provide An oxygen sensor (160) control module (100) for a vehicle, comprising input means (130) for receiving one or more signals (135) indicative of a likelihood of future engine cranking, an output means (140) to provide an output signal (145) to cause activation of a heater (150) associated with the oxygen sensor, and processing means (110) arranged to control, in dependence on the one or more signals (135) indicative of the likelihood of future engine cranking, the output means (140) to provide the output signal (145) to cause activation of the heater (150) associated with the oxygen sensor (160) prior to the engine cranking.

摘要： A control system for a vehicle, the control system comprising one or more controllers, the control system being arranged to: determine a prediction of an end of a current driving cycle of the vehicle, determine a likelihood of slippage from an emissions trap of the vehicle in a next driving cycle of the vehicle in dependence on the prediction of the end of the current driving cycle, and control purging of the emissions trap prior to the prediction of the end of the current driving cycle in dependence on the likelihood of slippage.

摘要： A control system for a vehicle, the control system having one or more controllers, the control system being arranged to: determine a likelihood of a NOx adsorber trap of a vehicle requiring purging; determine an efficiency of purging the NOx adsorber trap; determine an operating efficiency of a selective catalyst reduction system of the vehicle; determine a schedule for purging of the NOx adsorber trap of the vehicle in dependence on the likelihood of the NOx adsorber trap requiring purging, the efficiency of purging the NOx adsorber trap, and the operating efficiency of the selective catalyst reduction system; and control purging of the NOx adsorber trap according to the schedule.
