To ensure emission purification performance while curbing waste of power.SOLUTION: An on-vehicle device is mounted on a vehicle which has an internal combustion engine and an electric motor and travels using at least either the internal combustion engine or the electric motor as a power source. The on-vehicle device has an acquisition section, a calculation section, and a setting section. The acquisition section acquires a situation of the vehicle. The calculation section calculates a probability of start-up of the internal combustion engine on the basis of the situation acquired through the acquisition section. The setting section sets a target temperature of a catalyst installed in an exhaust passage of the internal combustion engine on the basis of the probability of start-up calculated by the calculation section so that the catalyst is preheated to the target temperature.SELECTED DRAWING: Figure 2
【課題】電力の浪費を抑えつつ、エミッション浄化性能を確保すること。【解決手段】実施形態に係る車載装置は、内燃機関および電動機を有し、かかる内燃機関および電動機の少なくともいずれかを動力源として走行する車両に搭載された車載装置であって、取得部と、算出部と、設定部とを備える。取得部は、車両の状況を取得する。算出部は、取得部によって取得された状況に基づいて内燃機関の始動確率を算出する。設定部は、算出部によって算出された始動確率に基づき、内燃機関の排気経路に設けられた触媒の目標温度を設定し、かかる目標温度となるように触媒を予熱させる。【選択図】図2
